Terror Lake Hydroelectric Project, FERC Project No. 2743   June 2015  Initial Statement  Before the Federal Energy Regulatory Commission  Application for Non‐Capacity Amendment to License    The Initial Statement is presented herein that addresses the FERC regulation 18 CFR 4.201(a).     (1) Kodiak Electric Association, Inc. (KEA) applies to the Federal Energy Regulatory Commission for a  non‐capacity amendment to license for the existing Terror lake Hydroelectric Project, FERC Project  No. 2743, as described in the attached exhibits.      (2) The exact name, business address and telephone number of the applicant are:    Kodiak Electric Association, Inc.  PO Box 787  Kodiak, Alaska 99615‐0787  907‐486‐7700    The exact name, business address, telephone number and e‐mail address of each person  authorized to act as agent for the application in this application are:    Darron Scott, President/CEO  Kodiak Electric Association, Inc.  PO Box 787, Kodiak, Alaska 99615‐0787  907‐486‐7707; dscott@kodiak.coop    Jennifer Richcreek, Regulatory Specialist  Kodiak Electric Association, Inc.  PO Box 787, Kodiak, Alaska 99615‐0787  907‐654‐7667; jrichcreek@kodiak.coop    (3) The applicant is a not‐for‐profit 501(c)12 rural electric cooperative, licensee for the water power  project, designated as Project No. 2743 in the records of the Federal Energy Regulatory  Commission, issued on the 5th day of October, 1981.    (4) The amendment of license proposed and the reason(s) why the proposed charges are necessary,  are:    To enable the construction and operation of a new diversion in a location where there is no existing  dam or diversion.  The Upper Hidden Basin Diversion (UHBD) would supplement the available  water supply for the existing Project by capturing additional snow melt and rain in the upper  reaches of the Hidden Basin watershed and conveying it westward through a mountain ridge to the  existing Terror Lake reservoir.  Once the additional water resource from the UHBD flows into the  Terror Lake reservoir, hydropower would be generated from the existing Project powerhouse and  fed directly into KEA’s existing grid without any operational changes or any other capacity‐related  modifications.  This new diversion would enhance the existing Project and allow KEA to provide a  continuous supply of renewable energy to the communities of Kodiak as electrical demand  continues to grow.  FERC License Amendment Application ‐ Upper Hidden Basin Diversion Initial Statement

(b) Exhibit A is a description of the Project.     Kodiak Electric Association, Inc. (KEA or Licensee) received an Order Issuing Major License and  Approving Joint Offer of Settlement (Order Issuing License) for the Terror Lake Project, FERC Project No.  2743 (Project) issued by the Federal Energy Regulatory Commission (FERC or Commission) on October 5,  1981 with an effective date of November 1, 1981.  License amendments were issued in 2004, 2008, and  2012 for tailrace remediation, Terror River instream flow averaging, and installation of a third turbine‐ generator unit, respectively.      The Project is a trans‐basin diversion development, capturing water from the Terror River Basin drainage  and the Kizhuyak River Basin and transporting it by means of an un‐pressurized tunnel to a powerhouse  located in the Kizhuyak River Basin. The existing principal features of the Project include: a 193 foot high  rockfill dam with an asphaltic concrete face constructed across the natural outlet of the existing Terror  Lake; a reservoir with a surface area of 1,020 acres at the normal maximum water surface elevation of  1,420 feet and 108,000 acre‐feet of usable storage between elevation 1,250 and 1,420 feet and 136,794  acre‐feet of gross storage capacity; five mile long power tunnel; three additional diversion structures on  tributaries of the Kizhuyak River which provide additional flows; a 3,400 foot long steel penstock; a  powerhouse at elevation 115 feet containing three 11.25 MW generating units, and a valve house at the  dam containing a 10 kW generating unit; a 2,200 foot long tailrace channel conveying flows from the  powerhouse to the main stem of the Kizhuyak River; a 13.8/138 kV switchyard; a 17.3 mile, 138 kV  transmission line from the powerhouse switchyard to a substation located on US Coast Guard property  near the City of Kodiak; and appurtenant facilities.    (1) The physical composition, dimensions, and general configuration of any dams, spillways, penstocks,  powerhouses, tailraces, or other structures, whether existing or proposed, to be included as part of the  project;     Proposed Modifications  KEA proposes to construct two new concrete face rockfill dams approximately 30 feet high and 250  feet wide within an eastern and western tributary branch of the West Fork of Hidden Basin Creek,  approximately six miles upstream of Hidden Basin Lagoon and Ugak Bay on the eastern side of Kodiak  Island, Alaska.  Surface water from the diversion dam on the eastern tributary (D‐East) would flow  through a half‐mile long, five foot diameter underground pipe to the diversion dam on the western  tributary (D‐West).  From there, surface water from both diversion dams would flow by gravity  through a 1.2 mile long, 12 foot diameter tunnel through a mountain ridge to Terror Lake, the main  reservoir for the Project.  The proposed diversion dams would include broad crested weir sections  that would provide adequate spillway capacity during periods of heavy rain and snow melt in excess  of the diversion’s conveyance pipe and tunnel hydraulic capacity.  Water flow in excess of the UHBD  conveyance pipe and tunnel capacity would be spilled downstream over the diversion dam spillways  into the West Fork of Hidden Basin Creek.  The proposed UHBD would also include a four mile long  spur road off of an existing road to provide access for constructing and maintaining the new diversion.       FERC License Amendment Application ‐ Upper Hidden Basin Diversion Exhibit A – Page 2  Kodiak Electric Association, Inc.  Pre‐Application Document  Terror Lake Hydroelectric Project, FERC Project No. 2743   June 2015  (2) The normal maximum surface area and normal maximum surface elevation (mean sea level), gross  storage capacity, and usable storage capacity of any impoundments to be included as part of the project;    No Changes to Impoundment  The proposed UHBD is a passive water conveyance design with minimal storage capacity behind two  minor diversion dam structures.  The proposed UHBD involves no change to the Terror Lake reservoir,  dam or spillway design.  The proposed UHBD would supply additional water resources to the Terror  Lake reservoir, but the normal maximum surface area (1,020 acres), normal maximum surface  elevation (1,420 EL), and usable storage capacity (108,000 acre‐feet) remain unchanged.        (3) The number, type, and rated capacity of any turbines or generators, whether existing or proposed, to  be included as part of the project;    No Changes to Powerhouse  There would be no changes to the existing powerhouse, turbines or generators.      (4) The number, length, voltage, and interconnections of any primary transmission lines, whether existing  or proposed, to be included as part of the project (see 16 U.S.C. 796(11));    No Changes to Transmission Lines  There would be no changes to the existing 138 kV transmission line.      (5) The specifications of any additional mechanical, electrical, and transmission equipment appurtenant  to the project; and    No Changes to Appurtenant Project Equipment  There would be no changes to the mechanical, electrical, and transmission equipment appurtenant to  the project.      (6) All lands of the United States that are enclosed within the project boundary described under  paragraph (h) of this section (Exhibit G), identified and tabulated by legal subdivisions of a public land  survey of the affected area or, in the absence of a public land survey, by the best available legal  description. The tabulation must show the total acreage of the lands of the United States within the  project boundary.    The proposed UHBD will require an expansion to the existing Project Boundary as shown in Exhibit G.      Proposed Change to Project Boundary   Current Project Use of Federal Lands Proposed Project Use of Federal Lands  Exclusive of Transmission Lines 4,146 acres Exclusive of Transmission Lines 4,148 acres Transmission Lines 136 acres Transmission Lines 136 acres Total Lands of the United States 4,282 acres Total Lands of the United States 4,284 acres   The Project’s licensed boundary currently occupies 4,282 acres of federal lands.  Of that total amount,  4,146 acres of the Project boundary is for the Terror Lake reservoir and western portions of the Project  access road and tunnel on federal land administered by the Kodiak National Wildlife Refuge.  The    FERC License Amendment Application ‐ Upper Hidden Basin Diversion Exhibit A – Page 3  Kodiak Electric Association, Inc.  Pre‐Application Document  Terror Lake Hydroelectric Project, FERC Project No. 2743   June 2015  remaining 136 acres is for the transmission line corridor on federal land administered by the US Coast  Guard and Bureau of Land Management.    Most of the UHBD would be constructed on lands owned by the State of Alaska.  By necessity of  connecting the water to the existing Terror Lake reservoir, some of the new UHBD would need to be  constructed on federal land already occupied by the Project and administered by the Kodiak National  Wildlife Refuge.  A portion of the proposed UHBD tunnel corridor would need to occupy 1.9 additional  acres of federal land administered by the Kodiak National Wildlife Refuge outside the current Project  boundary.  This 1.9 acre corridor of expanded Project boundary on federal land would be a subterranean  tunnel, completely underneath a mountain ridge.    FERC License Amendment Application ‐ Upper Hidden Basin Diversion                 Exhibit B – Page 1  Kodiak Electric Association, Inc.                  Pre‐Application Document  Terror Lake Hydroelectric Project, FERC Project No. 2743             June 2015    Exhibit B – Project Operation and Resource Utilization    Exhibit B is presented herein and addresses the FERC regulation 18 CFR 4.51 (c).      (1) A statement whether operation of the powerplant will be manual or automatic, an estimate of the  annual plant factor, and a statement of how the project will be operated during adverse, mean, and high  water years;    No Changes to Project Operation  There would be no changes to the Terror Lake Hydroelectric Project (Project) powerhouse equipment  or operations with the addition of the Upper Hidden Basin Diversion (UHBD).  The Project has  personnel on site continuously and the plant is controlled by the system dispatchers in Kodiak Electric  Association, Inc.’s (KEA’s or Licensee’s) Dispatch Center, located within the City of Kodiak.  The Project  will remain to be KEA’s primary source of electric power during adverse, mean and high water years.      The total plant capacity will remain to be 33,750 kilowatts (kW). A 100% plant capacity factor equates  to 296 million kilowatt‐hours (kWh).  The Project currently generates 135 million KWh annually.  The  new UHBD would add 30,000 acre‐feet of new water resources to the Project annually, equating to 33  million kWh of new energy production made available to the Project.  Therefore, the UHBD boosts the  annual plant capacity factor by making more hydropower resources available to the unchanged  Project powerhouse.   Current Plant Capacity Factor Proposed Plant Capacity Factor  46 % 56 %    (2) An estimate of the dependable capacity and average energy production in kilowatt‐hours, supported  by the following data:    No Change to Project Capacity  There would be no changes to the existing powerhouse, turbines or generators.  The total generating  capacity of the Project remains unchanged at 33.75 megawatts (MW).  Proposed Increase to Annual Energy Production  The Project’s average generating efficiency is 1,100 kWh per acre‐foot of water.  This generating  efficiency rate will remain unchanged because there would be no changes to the existing  powerhouse, turbines and generators.  The Terror Lake reservoir, Shotgun Creek Diversion, Falls  Creek Diversion, and Rolling Rock Creek Diversion (all to remain unchanged) currently provide on  average 123,000 acre‐feet of water resources annually to the Project for 135 million kWh of energy  production annually.  The proposed UHBD would provide an additional 30,000 acre‐feet of water to  the Project each year; therefore providing an additional energy resource equivalent to 33,000,000  kWh of annual energy production.  Current Annual Production Proposed Annual Production  135,000,000 kWh 168,000,000 kWh          FERC License Amendment Application ‐ Upper Hidden Basin Diversion

Kodiak Electric Association, Inc.                  Pre‐Application Document  Terror Lake Hydroelectric Project, FERC Project No. 2743             June 2015    Based upon Terror Lake current area‐capacity curve (Figure B‐4), historical and projected inflows to  Terror Lake (Figure B‐3), and KEA’s future projected load growth (Figure B‐7), the Terror Lake reservoir is  expected to provide ample storage capacity for utilizing the additional inflows provided by the new  UHBD.        During the very wet years, there is always the potential for lake spill if the Project’s available water  supply outpaces KEA’s hydropower production demand.  In those wet year situations, the Terror Lake  spillway has ample spillway capacity to pass excess water resource as needed, including the additional

There would be no changes to the existing powerhouse, turbines, generators, penstock, or Terror  Lake reservoir.     (3) A statement, with load curves and tabular data, if necessary, of the manner in which the power  generated at the project is to be utilized, including the amount of power to be used on‐site, if any, the  amount of power to be sold, and the identity of any proposed purchasers; and    With the exception of station service and transmission losses, all Project power is sold to KEA’s  Cooperative members.      KEA’s Pillar Mountain Wind Project provides on average 26 million kWh of wind energy production  annually.  Current conditions of the Project provide on average 135 million kWh of hydropower production  annually.  That brings KEA’s current renewable hydro‐wind power production portfolio to a total of 161  million kWh annually.  By 2020, KEA’s load growth demand is expected to exceed 179 million kWh,  requiring additional power beyond KEA’s current hydro‐wind power production levels.  The proposed  UHBD would provide additional water resources to the Project so that an additional 33 million kWh of  annual hydropower production may be added to KEA’s grid.  The full contribution of the UHBD is expected  to be fully utilized by 2025.

FERC License Amendment Application ‐ Upper Hidden Basin Diversion Exhibit D – Page 1  Kodiak Electric Association, Inc.  Pre‐Application Document  Terror Lake Hydroelectric Project, FERC Project No. 2743   June 2015    Exhibit D – Statement of Costs and Financing    Exhibit D is presented herein and addresses the FERC regulation 18 CFR 4.51 (e).     (e) Exhibit D is a statement of costs and financing.    (1)  N/A ‐ This is not an application for an initial license.      (2) N/A ‐ This is not an application for a new license.      (3) If the application includes proposals for any new development, a statement of estimated costs,  including:    (i) The cost of any land or water rights necessary to the new development    Most of the Upper Hidden Basin Diversion (UHBD) would be constructed on lands owned by the State of  Alaska, administered by the Department of Natural Resources (DNR).  The purchase of land is not  necessary for the new development.  Kodiak Electric Association, Inc. (KEA or Licensee) initiated the  application process with DNR in April, 2015 for securing land use and water use rights necessary to  construct and operate the UHBD.  As per the guidance of DNR staff, the exact cost of the land and water  rights associated with the proposed UHBD is not determined until after the UHBD is built and  operational.  Therefore, the cost of land and water rights necessary to the new development are not  known at this time.      (ii) The cost of the new development, with specification of:  (A) Total cost of each major item;   (B) Indirect construction costs such as cost of construction equipment, camps and commissaries;   (C) Interest during construction;    (D) Overhead, construction, legal expenses, taxes, administrative and general expenses, and  contingencies.      The total cost to develop the UHBD is estimated at $79,992,000, as itemized in the table below.    FERC  Account Major Item Total Cost  332 Diversion Dams & Conveyance $15,449,038  332 Tunnel $36,914,000  336 Access Road $4,923,000  Construction Subtotal $57,286,038  Escalation for Inflation 2015 – 2019 $9,855,962  Direct Construction Cost $67,142,000  Licensing Cost $2,500,000  Engineering and Owner Administration  $10,350,000  Total Construction Cost Estimate  $79,992,000    Indirect construction costs, such as construction equipment, are imbedded within the construction costs  listed above.  Interest during construction costs are not factored into the development cost at this time.   Infrastructure support for the construction, such as the construction camp with utilities, already exists at    FERC License Amendment Application ‐ Upper Hidden Basin Diversion Exhibit D – Page 2  Kodiak Electric Association, Inc.  Pre‐Application Document  Terror Lake Hydroelectric Project, FERC Project No. 2743   June 2015    the Terror Lake Hydroelectric Project (Project) site.  Building materials and associated equipment  needed to construct the UHBD would be transported to the Project’s existing jetty dock, transported on  the Project’s existing access road, and stored in the Project’s existing warehouse.  The electric energy  derived from the additional water resources supplied by the UHBD to the Terror Lake reservoir will be  generated by the Project’s existing infrastructure.  Operating the UHBD incurs no additional cost to the  current Project facilities (i.e., powerhouse, turbines, generators, switchyard, and transmission line).      (4) A statement of the estimated average annual cost of the total project as proposed specifying any  projected changes in the costs (life‐cycle costs) over the estimated financing or licensing period if the  applicant takes such changes into account, including:    (i)  Cost of capital (equity and debt);     The most recently received interest rate quote from KEA’s financing institutions was at 3.87%.  If  financing is provided by CoBank ACB, a member‐owned cooperative financing institution that returns  capital credits (dividends) on its loans, then the capital credits would provide approximately a 1%  interest rate reduction in the form of cash and credit back.  These capital credits are not factored into  the NPV or UHBD savings at this time.    (ii) Local, state and Federal taxes;     KEA is the sole owner of the Project, and is a generation, transmission and distribution not‐for‐profit  rural electric cooperative.  As a 501(c)12 not‐for‐profit organization, KEA is exempt from local, state, and  federal taxes.    (iii) Depreciation and amortization;     The industry average annual depreciation rate applied to hydroelectric facilities, and the RUS standard  under which KEA is governed, is 2%.  This equates to a 50‐year facility life.  When the total construction  cost estimate ($79,992,000) is divided by a 50‐year term, the annual depreciation expense of the UHBD  comes to $1,599,840.    Based upon KEA’s experience with its financing institutions, it is highly probable that the amortization of  the UHBD loan would be set at 30 years.  At a 3.87% interest rate, this provides for an annual interest  and principal payment of $4,518,764.  If financing is provided by CoBank ACB, a member‐owned  cooperative financing institution that returns capital credits (dividends) on its loans, then the capital  credits would provide approximately a 1% interest rate reduction in the form of cash and credit back.   These capital credits are not factored into the NPV or UHBD savings at this time.     (iv) Operation and maintenance expenses, including interim replacements, insurance, administrative and  general expenses, and contingencies; and    The UHBD components would be a basic, non‐mechanical design intended for un‐manned water  conveyance.  KEA has been operating and maintaining three other similar diversions at the Project for 30  years.  The cost to maintain these types of diversion structures is low.  No additional personnel would be  necessary to operate or maintain the UHBD.  Annual maintenance activities for the UHBD would consist  of an annual or biennial clearing of accumulated rock or silt debris behind the two diversion dams, which  is estimated to cost $150,000 in 2020.  KEA’s UHBD budget assumes a maintenance cost inflation rate of  3%.    FERC License Amendment Application ‐ Upper Hidden Basin Diversion Exhibit D – Page 3  Kodiak Electric Association, Inc.  Pre‐Application Document  Terror Lake Hydroelectric Project, FERC Project No. 2743   June 2015    (v) The estimated capital cost and estimated annual operation and maintenance expense of each  proposed environmental measure.    No proposed environmental measure costs are included in this proposal.    (5) Statement of the estimated annual value of project power based on the estimated average annual  cost of obtaining an equivalent amount of power (capacity and energy) from the lowest cost alternative  source, specifying any projected change in the cost of power from that source over the estimated  financing or licensing period if the applicant takes such changes into account.       If the UHBD were not built, the only other alternative source of viable power available to meet KEA’s  growing load demand is diesel fuel.  KEA is already pushing the technologic edge for wind penetration  with battery and flywheel energy storage system integration, and cannot add any more wind generation  to its grid.  The only other alternative for obtaining an equivalent amount of power is diesel‐based  generation.  KEA’s diesel‐generation efficiency is 14.2 kilowatt‐hours per gallon of diesel fuel.  KEA’s  historical average cost of diesel fuel is $3.14 per gallon.  In addition to the direct cost of diesel fuel,  diesel engine maintenance costs average 4¢ per kWh.  KEA’s UHBD Budget assumes a fuel and  maintenance cost inflation rate of 3%.    KEA proposes to have the UHBD operational by 2020.  KEA’s system load demand in 2020 is expected to  be 18 million kilowatt‐hours (kWh) greater than KEA’s currently available hydropower and wind energy  supply.  Therefore, without the additional water resources provided by the UHBD, the 18 million kWhs  of additional load demand would require diesel‐generated power.  Based on the diesel generation  efficiency rates and 3% inflation rates on fuel and maintenance costs, the direct fuel costs for generating  that amount of electricity without the UHBD is approximately $4.5 million, plus $818,825 in diesel  engine maintenance cost.  (See table below.)    Because the only other feasible alternative to power generation on Kodiak Island is diesel, the value of  the UHBD is exceptionally high.  Even with the expenses of constructing this new diversion, including  debt and maintenance costs, the first year benefits of the UHBD would be net positive at $676,666 in  savings.      Year 1 Costs Year 1 Savings  Debt cost $4,518,764 Savings from avoided fuel cost $4,526,605   Maintenance cost $150,000 Savings from avoided engine maintenance $818,825 Total Cost in Year 1 $4,668,764 Total Savings in Year 1 $5,345,430 NET SAVINGS in Year 1 = $676,666      The cost‐saving benefits of hydropower continue to escalate to $5.7 million in Year 5 of UHBD  operation.  Over the 30‐year financing term, a total of 66,947,372 gallons of diesel fuel are expected to  be saved from the additional hydropower production made possible by the water resources of the  UHBD.  The direct savings from the avoided fuel cost is $380 million, plus the additional $69 million in  savings from avoided diesel engine maintenance cost.      Compared to the diesel alternative, the net present value (NPV) at a 5% discount rate for the UHBD is  over $129 million.  That is a significant savings for the Kodiak community.      FERC License Amendment Application ‐ Upper Hidden Basin Diversion Exhibit D – Page 4  Kodiak Electric Association, Inc.  Pre‐Application Document  Terror Lake Hydroelectric Project, FERC Project No. 2743   June 2015    Other unquantifiable benefits of this project, such as the stabilized cost of power, energy independence,  reduction in pollution and greenhouse gasses, and the renewable energy marketing opportunities  provided to Kodiak’s business community are not included in this economic analysis; however, it should  be noted that those aspects of the project also increase the value of the UHBD and overall Terror Lake  Hydroelectric Project for the long‐term sustainable health of Kodiak.    (6) A statement specifying the sources and extent of financing and annual revenues available to the  applicant to meet costs identified in paragraphs (e)(3) and (4) of this section.      If KEA does not receive augmented financing or grants from a State or Federal renewable energy  initiative program, then KEA is prepared to take responsibility for the direct financing of the total  construction cost.  KEA is a rural electric cooperative with a long history with lending institutions able to  provide KEA with direct financing:  CoBank, ACB, National Rural Utilities Cooperative Finance  Corporation (NRUCFC), and US Department of Agriculture’s Rural Utilities Service (RUS).      KEA is held to specific financial standards with its Equity levels, Debt Service Coverage (DSC) and Times  Interest Earnings Ratios (TIER) as a condition of borrowing capacity.  KEA is a self‐regulated utility that  has the ability to adjust rates to ensure that revenue will continue to meet cost if necessary; however  the benefits that the UHBD  provides to the KEA membership through the reduction in costly diesel‐ powered generation is the justification and purpose of this project.  Once the capital expenditure is paid,  the long‐term savings provided by the UHBD are expected to reduce KEA’s overall revenue  requirements.    (7) An estimate of the cost to develop the license application;     The estimated cost to develop the FERC license application is $2,500,000.  This cost is included in the  total construction cost estimate of $79,992,000.    (8) The on‐peak and off‐peak values of project power, and the basis for estimating the values, for  projects which are proposed to operate in a mode other than run‐of‐river; and    The concept of on‐peak and off‐peak values of project power are not applicable to this proposal.  KEA is  the only electric utility in Kodiak and there would be no power purchase agreements.      The electric energy derived from the additional water resources supplied by the UHBD to the Terror  Lake reservoir will be generated by the Project’s existing infrastructure and would go straight into the  KEA grid.  Likewise, the project savings would go straight to the members of the Cooperative.  The  community would experience a lower cost of power from decreased diesel fuel consumption.  The high  value of the UHBD is described in further detail above.    (9) The estimated average annual increase or decrease in project generation, and the estimated average  annual increase or decrease of the value of project power, due to a change in project operations (i.e.,  minimum bypass flows; limits on reservoir fluctuations).      The proposal would not change the authorized installed capacity of the Project; however, the additional  water resources added to Terror Lake from the UHBD is expected to increase average annual generation  by an additional 33 million kilowatt‐hours.

Submitted to:  Federal Energy Regulatory Commission      Prepared and Submitted by Project Licensee:  Kodiak Electric Association, Inc.  Kodiak, Alaska                    June 2015    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page ii  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  Executive Summary  On October 5, 1981, the Federal Energy Regulatory Commission (FERC or Commission) issued a license  to Kodiak Electric Association, Inc. (KEA) for the Terror Lake Hydroelectric Project, FERC Project No. 2743  (Project). The Project is located in north central Kodiak Island in the Kodiak Island Borough  approximately 25 miles southwest of the City of Kodiak. The license was issued on October 5, 1981, with  an effective date of November 1, 1981.   The Project commenced commercial operation in 1985, and it  remains to be the primary source of KEA’s energy supply.    KEA is a rural electric cooperative that provides electricity to approximately 6,000 meters on Kodiak  Island, Alaska in a service area that includes the region in and around the City of Kodiak, Bells Flats,  Chiniak, Pasagshak, Port Lions, and the nation’s largest US Coast Guard Base.  The Terror Lake  Hydroelectric Project is the cornerstone to KEA’s award‐winning renewable energy system.  On an  annual average, KEA’s electric grid is powered with 80% hydropower from the Terror Lake Hydroelectric  Project and 20% wind energy from the Pillar Mountain Wind Project.  For 2014 and 2015 year‐to‐date,  KEA’s electric grid achieved a 99.7% renewable energy portfolio, with a 99.9% reliability factor.  KEA’s  success in developing its innovative hydro‐wind electric grid has eliminated diesel fuel as the  community’s primary power supply.    Annual energy production requirements for KEA’s grid in 2014 were 159 million kilowatt‐hours (kWh).   By 2020, KEA’s system‐wide load growth demand is expected to surpass 179 million kWh due to  expansions of Kodiak’s seafood processing sector, the repowering of the City’s shipping port crane,  numerous new building construction projects, and an overall community‐wide shift of energy sourcing  from diesel fuel to renewable electricity.  KEA’s isolated grid system is currently able to supply 161  million kWh of renewably generated electricity annually.  Without additional sources of renewable  energy to meet the upcoming load demand, KEA will need to revert back to diesel‐based generation.   Returning to a reliance on expensive, barged‐in diesel fuel is not an acceptable option for the future  viability of Kodiak’s economy and environment.    KEA’s vision is to maintain 95% of energy sales with cost effective renewable power solutions for the  future of their Cooperative members and the Kodiak community.  Optimizing KEA’s existing hydropower  resources is the solution to achieve this renewable energy vision.    There is a limited amount of water available within the Terror Lake reservoir, and when that available  energy supply is drawn down to low lake levels, more energy is needed to continue powering KEA’s  growing loads. KEA cannot add any more wind generation to the KEA grid, as it is already pushing the  technologic edge for its high levels of wind penetration with a unique energy storage system involving  both battery and flywheel technology.  Tidal and wave energy generation technology remains in the  pilot testing phase, and is not yet ready for utility‐scale deployment and operation.  Adding more water  to Terror Lake would be the most cost‐effective, and minimally‐invasive approach for adding more  renewable energy onto KEA’s isolated micro‐grid.    The Upper Hidden Basin Diversion (UHBD) is the most feasible energy project available to KEA.  This  diversion provides the KEA grid with the energy it needs, and it can be achieved through a straight‐ forward approach that utilizes existing power generation equipment.  KEA is ready to move forward  with this next step in our renewable energy vision.          Proposed Action  This Draft Application for Non‐Capacity Amendment to License, including the Preliminary Draft  Environmental Assessment (PDEA) (Draft Amendment Application) provides information in support of    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page iii  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  KEA’s proposed construction of the UHBD.  This new diversion would supplement the Project’s available  water supply by capturing additional snow melt and rain in the upper mountain tributaries of the West  Fork of Hidden Basin Creek and conveying it westward through a mountain ridge to the existing Terror  Lake reservoir.  The diversion components would be a basic, non‐mechanical design intended for un‐ manned water conveyance.  Once the additional water resources from the UHBD flow into the Terror  Lake reservoir, hydropower would be generated from the existing Project powerhouse and fed directly  into KEA’s existing grid without any operational changes or any other capacity‐related modifications.      The proposed UHBD would be located above 1,400 foot elevation in the mountainous uplands of Kodiak  Island, approximately six miles upstream of the Hidden Basin lagoon that flows into Ugak Bay on the  eastern side of Kodiak Island, Alaska.  The upper catchment area of the Hidden Basin watershed is  estimated to convey 30,000 acre‐feet of snow melt and rain.  The UHBD would add this 30,000 acre‐feet  of water to the Terror Lake reservoir by constructing two concrete‐face rockfill dams within an eastern  and western tributary branch of the West Fork of Hidden Basin Creek. Surface water from the diversion  dam on the eastern tributary (D‐East) would flow through a half‐mile long, five foot diameter  underground pipe to the diversion dam on the western tributary (D‐West).  From there, surface water  from both diversion dams would flow by gravity through a 1.2 mile long, 12 foot diameter tunnel  through a mountain ridge to Terror Lake.  Water flow in excess of the UHBD conveyance pipe and tunnel  capacity would be spilled downstream over the diversion dam spillways into the West Fork of Hidden  Basin Creek.  The proposed UHBD would also include a four mile long spur road off of an existing road to  provide access for constructing and maintaining the new diversion.  The proposal would not change the  authorized installed capacity of the Project; however, the additional water resources added to Terror  Lake from this diversion are expected to increase average annual generation by 33 million kWh.    Alternatives Considered  The UHBD is the most feasible and cost‐effective approach to supplying electric power in Kodiak.  KEA’s  load demand is growing because the community is switching its source of energy from fossil fuels to  locally‐ and renewably‐generated electricity.  It may seem counter‐intuitive that conservation efforts are  creating higher electric loads, but it is because of KEA’s success in providing its members with affordable  renewable energy that electricity makes better overall sense and savings per British Thermal Unit (BTU)  than fossil fuels.    KEA operates on a remote, completely isolated electric grid unconnected to any other electric system.   There are no local sources of natural gas, coal, or nuclear power on Kodiak Island, nor would it be  feasible to import any of those fuel sources to Kodiak due to transportation logistics, high cost, pollution  controls and safety requirements.  KEA is already pushing the technologic edge for variable wind energy  penetration on its isolated micro‐grid with battery and flywheel energy storage system integration, and  cannot practically engineer any more intermittent source energy, such as wind or solar, onto its system.   Tidal and wave energy generation technology remains in the pilot testing phase and is not yet ready for  utility‐scale deployment and operation.  Developing an entirely new hydropower facility separate and  redundant to the existing Project is not practical.  The only other alternative for obtaining an equivalent  amount of power other than the UHBD would be diesel‐based generation.  However, reverting back to a  dependence on barged‐in diesel fuel for local electric generation is not reasonable, due to both  economic and environmental costs.  The UHBD is the most viable option for supplying continuous  renewable power to KEA’s remote electrical grid.

Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  1. Introduction  On October 5, 1981, the Federal Energy Regulatory Commission (FERC or Commission) released an  Order Issuing Major License and Approving Joint Offer of Settlement (Original License) for the Terror  Lake Hydroelectric Project – FERC Project No. 2743 (Project) to Kodiak Electric Association, Inc. (KEA)  with an effective date of November 1, 1981.  The Project commenced commercial operation in 1985,  and it remains the primary source of KEA’s energy supply.   The Terror Lake Hydroelectric Project is a trans‐basin development, capturing water from the Terror  watershed and Kizhuyak River drainage and transporting it by means of tunnel to a powerhouse located  on the west bank of the Kizhuyak River.  (Refer to Figure A‐3, Conceptual Project Layout.)  The  powerhouse contains three 11.25 megawatt (MW) turbine‐generator units; each unit comprises a  vertical shaft 6‐jet Pelton turbine and synchronous generator. Two units were authorized in the Original  License issued on October 5, 1981, and the third unit was authorized in a Capacity Amendment to  License issued on February 17, 2012.    This Draft Application for Non‐Capacity Amendment to License, including the Preliminary Draft  Environmental Assessment (PDEA) (Draft Amendment Application) provides information in support of  KEA’s proposed construction of the Upper Hidden Basin Diversion (UHBD) located on the upper  tributaries of the Hidden Basin watershed.  KEA proposes to expand the Project with the addition of a  water conveyance diversion that brings water resources from the upper reaches of the Hidden Basin  watershed to the Terror watershed.  The UHBD components would be a basic, non‐mechanical design  intended for un‐manned water conveyance.      1.1 Purpose of and Need for Action   1.1.1 Purpose of Action  The Project is the primary source of KEA's energy supply, and is the cornerstone to KEA's renewable  wind‐hydro energy generation system. This Draft PDEA addresses construction of the UHBD.  This new  diversion would supplement the Project’s currently available water supply to boost hydropower  production at the existing facility so that KEA’s growing load demand can continue to be powered with  renewable energy.   The proposal would not change the authorized installed capacity of the Project;  however, the additional water resources added to Terror Lake from the UHBD are expected to increase  average annual generation of the Project by an additional 33 million kilowatt‐hours (kWh).  Diverting water from the Hidden Basin watershed was considered during the original design and  construction of the Project.  The 1978 Terror Lake Hydroelectric Project’s Definite Project Report stated:    “The Hidden Basin Creek diversion works are not included in the recommended development of  the Terror Lake Project at this time [1978].  However, this scheme is the most economical means  of increasing the output of the development above its presently projected level, and it can be  built whenever the growth in power demand in Kodiak justifies it.  Therefore, the scheme is  included in the present report as a recommended future development.”   KEA is familiar with the ground conditions and Project operation in this remote area of Kodiak Island.   KEA already operates and maintains three other diversions at the Project as part of the existing  hydropower system.  The proposed UHBD area is adjacent to existing Project lands, east of the Terror  Lake reservoir and south of the Shotgun Creek Diversion.  The proposed UHBD tunnel would run though  the same stable granitic ridge as the Terror Lake power tunnel. Based on KEA’s familiarity with this  region of Kodiak Island and observations from recent field surveys, KEA does not anticipate any  technological barriers to the development of this project.      FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 2  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  Adding more water to the existing Project would be the most cost‐effective and minimally‐invasive  approach for adding more renewable energy onto KEA’s isolated grid.  The UHBD is the next step  necessary for KEA to achieve its vision statement: “Endeavor to maintain 95% of energy sales with cost  effective renewable power solutions for the future of our members and the community.” Enhancing KEA’s  wind‐hydro system with the additional hydro resource of Upper Hidden Basin makes it possible for KEA  members to displace diesel fuel as an energy and heat source in their homes and businesses, and it  supports Kodiak’s economic growth in the global seafood industry.  The energy independence provided  by KEA’s wind‐hydro system is a significant benefit for the remote island community of Kodiak.  With the  UHBD, Kodiak can continue to rely on affordable, locally‐generated, clean energy as the foundation for  the community’s quality of life.      1.1.2 Need for Action  KEA provides electricity to approximately 6,000 meters on Kodiak Island, Alaska in a service area that  includes the region in and around the City of Kodiak, Bells Flats, Chiniak, Pasagshak, Port Lions, and the  nation’s largest US Coast Guard Base.  KEA's system operates in a remote island environment with no  interconnections to outside sources of power.  (Refer to Figure A‐2, KEA Service Area.)    The Terror Lake Hydroelectric Project is the cornerstone to KEA’s renewable wind‐hydro energy system.   On an annual average, KEA’s electric grid is powered with 80% hydropower from the Project, and 20%  wind energy from the Pillar Mountain Wind Project.  KEA’s renewable hydro‐wind generation system is  currently able to supply 161 million kWh of electricity annually to its isolated grid.  Annual energy  production requirements for KEA’s grid in 2014 were 159 million kWh, and this energy demand was  powered by KEA’s 99.7% renewable energy portfolio.  However by 2020, KEA’s system‐wide load growth  demand is expected to exceed 179 million kWh due to expansions of Kodiak’s seafood processing sector,  the repowering of the City’s shipping port crane, numerous new building construction projects, and an  overall community‐wide shift of energy sourcing from diesel fuel to renewably‐generated electricity.  Without additional sources of renewable energy to meet the growing load demand, KEA reverts back to  diesel‐based generation.  Returning to a reliance on expensive, barged‐in diesel fuel is not an acceptable  option for the viability of Kodiak’s economic and environmental future.    KEA’s load demand is growing because the community is developing new infrastructure based on  renewable electricity as the local energy solution.  It may seem counter‐intuitive that conservation  efforts are creating higher electric loads, but it is because of KEA’s success in providing its members with  affordable renewable energy that electricity makes better overall sense and savings per British Thermal  Unit (BTU) than fossil fuels.  KEA does not want to fall into the same dilemma other Alaskan utilities  have faced when growing loads outpace the supply of renewable energy.    There is a limited amount of water available within the Terror River watershed, and when available  energy supply is drawn down to low reservoir levels, more energy is needed to continue powering KEA’s  growing loads.  KEA’s grid cannot integrate additional wind energy at this time.  Stably integrating 80%  wind penetration rates on an isolated micro‐grid is an unprecedented electrical engineering feat that  KEA achieved by building its innovative electrical infrastructure to balance the variability of high  penetration wind energy with stored energy injections from flywheels, battery arrays, and hydropower.   KEA is already pushing the technologic edge for integrating its current levels of wind energy.  The  additional energy needed on KEA’s system will not come from wind.  KEA continues to examine the  potential for other forms of renewable resource development such as solar, tidal, run‐of‐the‐river, and  wave energy; however, those forms of energy are also variable and intermittent like wind energy.  The  stable integration of these variable forms of energy on KEA’s isolated micro‐grid has reached its  maximum under KEA’s current conditions.  Further, tidal and wave energy generation technology    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 3  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  remains in the pilot testing phase, and is not yet ready for utility‐scale deployment and operation.  There  are no local sources of natural gas, coal, or nuclear power on Kodiak Island.  It would not be feasible to  import natural gas, coal, or nuclear fuel to Kodiak due to transportation logistics, high cost, safety  precautions, and pollution control requirements.  Developing an entirely new hydropower facility  separate and redundant to the existing Project is not practical.  The only other alternative for obtaining  an equivalent amount of power is diesel‐based generation.  However, reverting back to a dependence  on barged‐in diesel fuel for local electric generation is not reasonable, due to both economic and  environmental costs.    Enhancing existing hydropower assets with a new diversion that brings more water to the Project is the  most practical, cost‐effective and minimally‐invasive option available for adding renewable energy to  KEA’s electrical grid system.  The UHBD is the most viable option for supplying continuous renewable  power to KEA’s remote electrical grid.        1.2 Description of the Application Process  This Draft Amendment Application, including the Draft PDEA, involves KEA’s request to construct and  operate a new diversion in a location where there is no existing dam or diversion as part of the existing  FERC License No. 2743.  When a licensee proposes to add a new diversion to an existing project, the  Commission’s regulations and terms of the license require that the licensee file an application for  amendment for Commission approval.    1.2.1 Applicant   KEA is a not‐for‐profit 501(c)12 rural electric cooperative and is not claiming preference under section  7(a) of the Federal Power Act (FPA). KEA owns and operates the existing Project.    1.2.2

Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  2. Proposed Action and Alternatives   Construction and operation of the UHBD is not anticipated to result in significant environmental impact.  The purpose of the proposal is to divert a small portion of water resources from the upper reaches of  the Hidden Basin watershed to the Terror watershed for renewable energy production.  The UHBD  would be similar to existing diversion structures currently in operation at the Project.  For the past 30  years, KEA has proven that it can successfully and responsibly construct and operate these types of  structures in this environment without adverse effects.    The UHBD comprises only 15% of the overall Hidden Basin watershed size, and is located above two  large waterfalls in a mountainous tundra area where no fish have been observed.  No threatened or  endangered species are located within the vicinity of this area.  There would be minimal change in the  facility’s aesthetic appearance, and there is no recreational or other public use at the site.    Constructing the new diversion dams and access road will require structures to be placed within  tributary creeks and wetlands; however, this activity is routinely authorized under license and permit  terms and conditions that specify best management practices requirements to minimize potential  impacts to the aquatic and terrestrial environments for this type of activity.  The minor impacts incurred  by temporary construction activities are far outweighed by the long‐term benefits associated with  minimizing the pollution associated with fossil fuel consumption achieved by enhancing renewable  energy infrastructure with this hydropower diversion.    KEA initiated field studies of the proposed UHBD and the downstream Hidden Basin Creek area in 2013.   The scope of studies completed to date include surface water stream gauging; watershed hydrology; fish  presence, absence and distribution; preliminary wetland assessment; cultural resources; conceptual  engineering design; and conceptual construction cost estimate.  The scope of studies currently in  progress for 2015 include ongoing surface water stream gauging; watershed hydrology; fish presence,  absence and distribution; and surveying and mapping.  Historical data are available from surface water  gauging of Hidden Basin Creek conducted by the US Geologic Survey (USGS) from 1982 to 1984.    The following Table 2‐1 provides an overview of the resource issues identified to date and provides  clarifying statements regarding whether a particular resource would be affected.  The table also  provides proposed measures that KEA would implement to avoid any adverse environmental effects  during the construction and operation of the UHBD.      Table 2‐1 Overview of Resource Issues

the upper reaches of the Hidden Basin watershed to the Terror watershed.  The UHBD components  would be a basic, non‐mechanical design intended for un‐manned water conveyance.  KEA proposes to construct two new concrete face rockfill dams approximately 30 feet high and 250 feet  wide within an eastern and western tributary branch of the West Fork of Hidden Basin Creek,  approximately six miles upstream of Hidden Basin Lagoon and Ugak Bay on the eastern side of Kodiak  Island, Alaska.  Surface water from the diversion dam on the eastern tributary (D‐East) would flow  through a half‐mile long, five foot diameter underground pipe to the diversion dam on the western  tributary (D‐West).  From there, surface water from both diversion dams would flow by gravity through  a 1.2 mile long, 12 foot diameter tunnel through a mountain ridge to Terror Lake, the main reservoir for  the existing Project.  The proposed diversion dams would include broad crested weir sections that would  provide adequate spillway capacity during periods of heavy rain and snow melt, and any amount water  flow that exceeds the capacity of the UHBD conveyance pipe and tunnel would be spilled into the West  Fork of Hidden Basin Creek.  The proposed UHBD would also include a four mile long spur road off of an  existing road to provide access for constructing and maintaining the new diversion.  (Refer to Figure A‐4,  Conceptual UHBD Layout.)    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 13  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  The proposal would not change the authorized installed capacity of the Project or any other feature of  the existing Project; however, the additional water resources added to Terror Lake from this new  diversion are expected to increase average annual generation by an additional 33 million kWh.  2.1.1 Project Location  Kodiak Island, located in the Gulf of Alaska, is the largest island in Alaska and second largest island in the  United States (US).  It is 252 air miles south of Anchorage, Alaska (a 45‐minute flight) and a 4‐hour flight  from Seattle, Washington. Kodiak Island contains the Kodiak National Wildlife Refuge which  encompasses nearly 1.9 million acres of land on Kodiak and Afognak Islands.  The largest city on Kodiak  Island is the City of Kodiak (City), located within the Kodiak Recording District and Kodiak Island Borough  (KIB) near the northeastern tip of Kodiak Island.  The Terror Lake Hydroelectric Project is located  approximately 25 air miles southwest of the City.  (Refer to Figure A‐1, Site Location Map and Figure A‐2,  KEA Service Area.)  This Draft Amendment Application involves a new diversion in the mountainous uplands of the Hidden  Basin watershed, east of the existing Terror Lake reservoir on Kodiak Island at approximately 57˚ 36’ 30”  North, 153˚ 0’ 10” West.  The proposed UHBD would be located on upper tributaries of the West Fork of  Hidden Basin Creek, approximately six miles upstream of Hidden Basin Lagoon and Ugak Bay.  Most of the UHBD would occupy land owned by the State of Alaska.  The proposed action’s new road  and conveyance structures would add approximately 160 acres to the existing FERC licensed boundary  of the Project.  Of this 160 acres, approximately 140 acres would encompass a new access road that  would connect the existing Project access road to the proposed UHBD site for construction, and  subsequent inspection and maintenance.  Approximately 15 acres of the proposed Project boundary  expansion would encompass the two diversion dam structures on State land, and the remaining 5 acres  would encompass a subterranean tunnel that would connect the UHBD dams to the Terror watershed.   The tunnel outlet portal on the Terror Lake side of the mountain ridge would be located in an area  already encompassed by the existing FERC licensed Project boundary.    A detailed map of the proposed revisions to the FERC‐licensed Project boundary are provided in Draft  Exhibit G – Project Map.     2.1.2 Use of Existing Facilities   The electric energy derived from the additional water resources supplied by the UHBD to the Terror  Lake reservoir will be generated by the Project’s existing infrastructure.  KEA’s current infrastructure is  already able to utilize the water resources provided by the UHBD to generate the additional hydropower  and deliver the renewable electricity to KEA’s service area.  The existing infrastructure associated with  the Project will continue to operate in the same manner without design or engineering changes.   Specifically,    There would be no changes to the Terror Lake dam, spillway, intake structure, Terror River  outlet works, power tunnel or penstock;    There would be no changes to the Shotgun Creek, Falls Creek, or Rolling Rock Creek Diversions;      There would be no changes to the existing powerhouse, turbines, generators or tailrace;     There would be no changes to the existing 138 kilovolt transmission line; and     There would be no changes to any other mechanical, electrical, or transmission equipment  appurtenant to the Project.      FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 14  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  The Project is remote, and is not accessible via the Kodiak road system.  Access to the Project site is only  possible by floatplane, helicopter, or boat.  KEA maintains the Project’s existing dock/jetty area, located  at the head of Kizhuyak Bay for transporting material and personnel to and from the Project.  The  dock/jetty area would be used to accommodate delivery of equipment and material for the construction  of the UHBD.  Material would be offloaded at the dock/jetty area and trucked to the UHBD site using the  Project’s existing access road.  The length of road from the dock/jetty to the area where a new UHBD  spur road would be constructed is approximately ten miles.  A new access road spur would connect this  existing road to the new D‐West and D‐East diversion dams of UHBD.    Infrastructure support for temporary construction personnel already exists at the Project.   A fully‐ functioning single‐family home can house a small construction crew, up to eight people.  For larger sized  construction crews up to 30 people, an additional contractor camp is available onsite with hook‐ups for  electricity, potable water, and sewer.  Once the UHBD is built, no additional KEA staff would be  necessary to operate or maintain the UHBD.    As a requirement for all contractor work conducted at the Project site, KEA employs standard Contract  Terms and Conditions ‐ Special Provisions Related to Safety and Environmental Protection (Contract  Terms and Conditions) to advise contractor personnel that they shall comply with all environmental

The Project’s total plant capacity will remain unchanged at 33.75 MW.  A 100% plant capacity factor  equates to 296 million kWh.  The Project’s average generating efficiency is 1,100 kWh per acre‐foot of  water.  This generating efficiency rate will remain unchanged because there would be no changes to the  existing powerhouse, turbines and generators.  The Terror Lake reservoir, Shotgun Creek Diversion, Falls  Creek Diversion, and Rolling Rock Creek Diversion (all to remain unchanged) currently provide on  average 123,000 acre‐feet of water resources annually to the Project for producing 135 million kWh of  energy.  The proposed UHBD would provide an additional 30,000 acre‐feet of water to the Project each  year, equating to 33 million kWh of new energy production available for the Project.  Therefore the  UHBD boosts the annual plant capacity factor by delivering additional water resources to the unchanged  Project powerhouse.    The proposed UHBD involves no change to the Terror Lake reservoir, dam or spillway design.  With the  Terror Lake dam and spillway unchanged, the Project’s gross storage capacity and usable storage  capacity provided by the Terror Lake reservoir remains unchanged.  The proposed UHBD would supply  additional water resources to the Terror Lake reservoir, but the normal maximum surface area (1,020  acres), normal maximum surface elevation (1,420 EL), and usable storage capacity (108,000 acre‐feet) of  the Terror Lake reservoir would remain unchanged.  The current volume of the Terror Lake reservoir is  Falls Creek Diversion Terror Lake Shotgun Creek Diversion Rolling Rock Creek Diversion Powerhouse Tailrace Kizhuyak River Terror River Proposed UHB Diversion   FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 17  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  adequate to utilize the additional inflows provided by the proposed UHBD under future projections of  electrical load demand.  The Project has no license‐mandated lake level elevation rule curve.  Terror  Lake’s minimum lake level elevation is 1,250 feet.  Maximum lake level elevation is 1,420 feet, which is  the elevation of the Terror Lake dam spillway.  The Project’s lake levels would continue to be managed  to ensure compliance with its Terror River instream flow requirements as per FERC License Article 43.   On average, the total future inflows to Terror Lake with the new inflows contributed by the proposed  UHBD are expected to be fully utilized by 2025.  Kodiak’s electric load demand is growing, additional  hydropower production is needed, and the Terror Lake reservoir provides usable storage capacity.   Terror Lake’s lake level elevation is expected to be drawn down lower in the future than current lake  levels due to growing load demand and the need for the Project to provide usable storage capacity for  the UHBD inflow, but the minimum lake level would not be drawn down below the 1,250 EL minimum  and the maximum lake level would remain 1,420 EL.  During the very wet years, there is always the  potential for lake spill if the Project’s available water supply outpaces KEA’s hydropower production  demand.  In those wet year situations, the Terror Lake spillway has ample spillway capacity to pass  excess water resource as needed, including the additional inflows provided by the proposed UHBD.  The  maximum inflow from the proposed UHBD to the Terror Lake reservoir would be limited by the  hydraulic capacity of the UHBD tunnel size, which at this stage of the conceptual design is estimated at  950 cubic feet per second (cfs).  Any future change to Terror Lake’s annual lake level drawdown,  recharge, or spill rates has no impact to any of the Project’s license‐mandated compliance obligations.    With the exception of station service and transmission losses, all power generated by the Project is sold  to KEA’s Cooperative members.  The full contribution of the UHBD inflows are expected to be fully  utilized by 2025.    At this time, KEA has no plans for additional Project developments other than the UHBD.       2.1.4 Project Benefits  The benefit of the UHBD is the supply of additional hydroelectric generation to KEA’s existing renewable  generation system with minimal equipment and infrastructure.  This diversion is estimated to add 33  million kWh of energy annually to the Project, which goes straight into the KEA grid for the direct benefit  of KEA’s Cooperative Member‐Owners.  This additional hydroelectric generation would allow KEA to  continue meeting growing loads, power a community‐wide shift in energy consumption from diesel fuel  to renewable electricity, and support Kodiak’s waterfront as the regional processing hub for Alaska’s  seafood industry.    The Pillar Mountain Wind Project and the Terror Lake Hydroelectric Project currently provide 99% of  KEA members’ electric needs with renewable wind and hydropower; however, KEA’s load growth has  intensified as the community displaces costly diesel fuel with clean, affordable electricity.  A trend is  emerging with replacing old petroleum‐based furnaces to new electric‐based systems for space and  water heat.  New home construction in town and on the US Coast Guard Base is installing electric‐based  systems for their water and space heating needs.  Additionally, Kodiak’s seafood industry is poised for  significant expansion as Kodiak becomes a regional processing hub for Gulf of Alaska commercial  fisheries.  A new seafood processing plant and a new electric‐powered port crane currently under  construction on Kodiak’s waterfront will become major sources of new load growth.  Now is the time to  plan for adding more renewable energy to KEA’s system so these growing loads can continue to be met  with renewable sources of energy instead of diesel‐powered generation.  Moving forward with the  UHBD development now allows KEA to be prepared for Kodiak’s future electrical demand by 2020.          FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 18  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  The UHBD would provide 30,000 acre‐feet of additional water resources to an existing hydropower  generating facility for KEA to provide a continuous supply of renewable energy to the Kodiak’s growing  electrical demand.  Once the water resource from the UHBD flows into the existing Terror Lake  reservoir, an additional 33 million kWh of hydropower could be generated from the existing Project  powerhouse and fed directly into KEA’s existing grid without any operational changes or any other  capacity‐related modifications.    A detailed analysis of the economic savings and value the UHBD provides to KEA’s electric system is  presented in Draft Exhibit D – Statement of Costs and Financing. An analysis of the overall power and  economic benefits of the UHBD is provided in Section 4 ‐ Developmental Analysis of this PDEA.     2.2 Alternatives   There are only two sources of energy that can be added to KEA’s grid at this time:  diesel fuel (the no‐ action alternative) and hydropower (the proposed action).  The no action alternative (use of diesel fuel  for additional energy) is discussed below along with alternatives considered but eliminated from further  analysis.  Due to constraints of fuel availability and air quality regulations associated with burning diesel fuel,  diesel‐based generation is not a reasonable alternative for supplying electricity in a manner as  practicably as the UHBD.  In light of this unique situation, KEA has determined that there are no other  reasonable alternatives to accomplish the stated purpose of adding more energy to KEA’s isolated grid  other than supplementing the available water supply at the Project with the UHBD.      2.2.1 No‐Action Alterative   Under the no‐action alternative, the Commission would deny the proposed construction and operation  of the UHBD.  The Project would continue to operate under the conditions of the existing license.    The no‐action alternative would impair the ability of KEA to provide a continuous supply of renewable  energy for the benefit of the Kodiak community.  Denial of the proposed UHBD would require KEA to  burn fossil fuel in its diesel generator units with the consequences of continued air emissions and  exposure of KEA members to high costs associated with diesel‐based generation.  Denial of the  proposed UHBD would negate the efforts of the local community to modernize its energy infrastructure  with renewable energy and eliminate dependence on diesel fuel.    Reverting back to a dependence on barged‐in diesel fuel for local electric generation is not reasonable,  due to both economic and environmental costs.  The future vision for the Kodiak community is to reduce  diesel fuel consumption, not return to it.  Other renewable sources of energy are not feasible for KEA,  per the discussion in Section 2.2.2 below.      2.2.2 Other Alternatives Considered but Eliminated from Further Analysis  Other alternatives considered were: curtailing electric load demand, additional wind sources, new  hydropower generation facilities, new renewable energy sources (solar, tidal, run‐of‐river, and wave),  natural gas, coal, and nuclear power.  These alternatives were not found to warrant further analysis for  the following reasons:   Curtailing electric load demand to below KEA’s 161 million kWh of available renewable energy  supply through conservation measures is not a reasonable solution to Kodiak’s specific energy

Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  circumstances, as it disregards the community‐wide shift away from diesel fuel consumption as  well as the growth occurring in the community’s industrial sector.     KEA is already pushing the technologic edge for wind energy penetration on its isolated micro‐ grid with battery and flywheel energy storage system integration, and cannot practically  engineer any more wind energy additions to its system.     KEA has investigated other potential sites on Kodiak Island for hydropower development;  however, it was determined not practical or cost‐effective to license, build and operate an  additional hydropower facility redundant to the existing generation and transmission  infrastructure of the Project.   There are no other viable diversion sites within the vicinity of the Project able to supply water  resources to the Project powerhouse.     The stable integration of variable energy forms such as solar, tidal, run‐of‐river hydroelectric,  and wave energy on KEA’s isolated micro‐grid has reached its maximum under KEA’s current  conditions.  Further, tidal and wave energy generation technology remains in the testing phase,  and is not yet ready for utility‐scale deployment and operation.     There are no local sources of natural gas, coal, or nuclear power on Kodiak Island.  It would not  be feasible to import natural gas, coal, or nuclear fuel to Kodiak due to transportation logistics,  high cost, safety precautions, and pollution control requirements.             FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 20

Environmental Analysis  Information presented in this Section addresses the requirements of the NEPA Environmental  Assessment and the FERC regulation for the Environmental Exhibit E [18 CFR 4.51(f)].  Information  provided within this Section is based on KEA’s understanding of the resources at the pre‐filing stage of  consultation.  Following the Joint Public/Agency Meeting on July 21, 2015 and comments received  during the period of public notice for this Draft Amendment Application, KEA will revisit and revise this  Section as necessary.      3.1 General Description of the Area Affected by the Proposed Action  3.1.1 Climate  Kodiak Island is known for its maritime climate, which is mild by Alaska standards.  The climate is  dominated by a strong marine influence that produces frequent cloudy skies, moderately heavy  precipitation, and relatively cool mild temperatures year round.   In general, temperature patterns are characterized by cool summers and, compared to the rest of south  central Alaska, warm winters.  The range between mean annual maximum and mean annual minimum  temperatures is small throughout the region.  The average summer maximum temperatures occur in  July or August and range from 14 to 16 degrees Celsius (C). The coldest average winter minimum  temperatures drop to ‐5 to ‐7 degrees C in December.  Average temperature differences between air  and water are greatest during fall and winter when the air is as much as 4 degrees C colder than the  water. This unstable condition results in air near the water surface being warmed, maintaining clouds at  a higher level than during spring and summer months when the air is warmer than the water.  Average rainfall is 67.6 inches per year and average snowfall is 78.7 inches per year.   Precipitation  during periods of 24 hours or less can be heavy enough to cause flooding.  February is the month with  the highest storm frequency and the greatest intensity of the Aleutian Low (a persistent low pressure in  the outer Aleutian Islands area), and July is the month with the lowest storm frequency and least  intensity of storms. Due to its elevation, steepness and terrain shading, snow can remain in the UHBD  area well into the month of June.   The hydrology in Hidden Basin Creek is characterized by a spring snowmelt as well as flashy, short  duration high flow events associated with heavy precipitation throughout the year. This is evident on  the hydrographs as steep spikes with very little ascending or descending lag time prior to or after the  peak flow. Persistent rain throughout the year saturates the soil and underdeveloped flood plains  through much of the basin resulting in an abrupt increase in the surface water discharge shortly  following precipitation events. During the early spring months it is not uncommon to receive heavy rain  on a deep snow pack, accelerating the rate of snow melt with latent heat of precipitation.  Detailed  hydrographs of the Hidden Basin watershed are presented in ERM’s report, Hidden Basin Creek  Hydrology and Fisheries Report, Technical Report February 2015 which is provided in Appendix C –  Technical Reports.    3.1.2 Air Quality and Noise  Alaska is a State Implementation Plan‐approved state with jurisdiction over the national air quality  standards required by the Clean Air Act.  The ADEC Air Permit Program has classified the air quality  surrounding the Project area as in attainment or unclassified with respect to the National Ambient Air  Quality Standards for particulate matter smaller than 10 micrometers, sulphur dioxide, nitrogen dioxide,    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 21  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  and carbon monoxide.  Federal Prevention of Significant Deterioration and Alaska air quality regulations  designate the Project area as a Class II area. (ADEC, 2015).  There is no noise monitoring data available and no monitoring is currently being collected.  Due to the  remote site and the lack of development, there is no noise pollution within the Project area (FERC,  1981).  3.1.3 Topography  The landscape of northwest Kodiak Island is characteristic of glaciation as evidenced by long, narrow  fjords, and u‐shaped valleys. The Hidden Basin watershed in northcentral Kodiak Island originates in a  mountainous area east of the Terror Lake reservoir.  Hidden Basin Creek is short and steep, originating  at an elevation of 2,500 EL and flowing south six miles into Hidden Basin, a natural saltwater lagoon,  before discharging into Ugak Bay and the Gulf of Alaska.   The proposed UHBD area would be located in the headwaters of the West Fork of Hidden Basin Creek.  (Refer to Figure A‐8, Hidden Basin Watershed.)  The upper tributary geomorphology of Hidden Basin  Creek is characterized by high gradient step‐pool morphology, large boulder/bedrock substrate, rapids,  and waterfalls interspersed with pools and undercut banks. The proposed UHBD dams would be located  in this steep headwater area at approximately 1,530 EL where the tributaries are approximately 2,000  feet apart.  Downstream and below the proposed UHBD, the gradient steepens and drops over a waterfall canyon.   Below this sharp drop, the gradient flattens and the valley broadens in a meadow area. (Refer to Photo  B‐16, Aerial View of Upper Meadow.)  The creek bed in this meadow area braids through fluvial  floodplains and surface flows are dominated by riffles over a smaller boulder/cobble substrate. Several  tributaries converge in this meadow, each contributing to surface flows. A tributary entering from the  southwest originates in glaciated mountains and contributes flow to the drainage year round.   Downstream of the meadow, the gradient steepens again through the lower canyon section of the West  Fork of Hidden Basin Creek and drops again over another tall vertical waterfall where the surface waters  are confined by steep bedrock cliff walls. (Refer to Photo B‐17, Lower Waterfall Barrier.)  The gradient  substantially flattens again before exiting the canyon, transitioning from a boulder/bedrock step‐pool to  boulder/cobble riffle morphology.   The Middle, East and West Forks of Hidden Basin Creek join at the canyon mouth forming the mainstem  of Hidden Basin Creek.  (Refer to Photo B‐18, Convergence of West, Middle and East Forks of Hidden  Basin Creek; and Photo B‐19, Aerial View of Mainstem of Hidden Basin Creek.)  Several unnamed  tributaries provide additional surface water inputs along the three mile length of the mainstem. Two of  these mainstem tributaries contain lakes in their headwaters which provide storage to help maintain  base flows in the lower reaches of Hidden Basin Creek. The mainstem of Hidden Basin Creek has a  relatively flat gradient characterized by a meandering channel with multiple channel braids.  The  substrate is dominated by alluvial materials consisting of small gravels interspersed with large cobbles  and boulders transported during peak flow events. The outfall is an inter‐tidal estuary where channel  depth varies dramatically between high and low tide.3  (Refer to photo B‐22, Aerial View of Mainstem  and Intertidal Reach of Hidden Basin Creek.)

Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  3.1.4 Vegetative Cover  Tundra occurs above 1,500 EL and consists primarily of two closely related vegetative community types.   The more prevalent of these is a carex‐forb meadow found on moist slopes.  Characteristic species are  carex sedges, artic bluegass (Poa arctica), lutkea (Luetkea pectinata), sweet coltsfoot (Petasites  hyperboreus), lupine (lupines sp.), coastal fleabane (Erigeron peregrinus), and Indian paintbrush  (Castilleja sp.).   Ridgetops with well‐drained soil and barren, rocky patches support the fell field  community that has many of the same species as the carex‐forb meadow, but can be distinguished by  the presence of such plants as crowberry (Empetrum nigrum), alpine azalea (Kalmia procumbens),  Kamchatka rhododendron (Rhododendron camtschaticum), Alaska moss heath (Polytrichum sp.), and  blueberry (Vaccinium sp.).  (FERC, 1981).   3.1.5 Land Development and Population Size  The Project is located in a remote area of northcentral Kodiak Island in the KIB approximately 25 miles  west of the City.  (Refer to Figure A‐1, Site Location Map and Figure A‐2, KEA Service Area.)  According to  the KIB GIS records (KIB GIS Website, 2015) there are seven privately owned lots equipped with tax‐ assessed buildings along the southwestern shores of Hidden Basin lagoon at the mouth of Ugak Bay  (Refer to Photo B‐24, Aerial View of Southwestern Shore of Hidden Basin Lagoon).  These lots are  located west and south of the Hidden Basin Creek delta.  The Alaska Community Database Community Information Summaries (DCED, 2015) lists the 2010  Certified Population for the Borough as 13,592; of which the City population is 6,130, the US Coast  Guard Base is 1,301 and Port Lions is 194. The City is the eighth largest city in Alaska in terms of  population.   3.2 Scope of Cumulative Effects Analysis    Pursuant to the Council on Environmental Quality regulations for implementing NEPA at 40 CFR 1508.7,  cumulative effect is the impact on the environment which results from the incremental impact of the  action when added to other past, present, and reasonably foreseeable future actions regardless of  which agency (federal or non‐federal) or person undertakes such other actions.  Cumulative impacts can  result from individually minor, but collectively significant, actions taking place over a period of time.  Actions to be considered include both hydropower and other land and water development activities in  the vicinity of the UHBD.   The UHBD area is remote and undeveloped.  There are no developments in the Hidden Basin watershed.   There are no towns located within 15 miles of the Project.  The only activity in the vicinity of the Project  are KEA staff who operate and maintain the Project equipment and facilities. There are no past land use  activities that have contributed to cumulative effects in the vicinity of the UHBD area.  KEA is not aware  of any activities that may be potential actions qualifying as past, present, or reasonably foreseeable  future actions to be analyzed under this cumulative effects analysis.    The additional hydropower production made possible by the water resources of the UHBD saves 23,744  metric tons of greenhouse gas (GHG) from being emitted to the atmosphere each year by diesel‐ powered generation (no‐action alternative).  The proposed UHBD is a reasonable approach to pollution  prevention and resource protection measure for climate and ocean acidification.       FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 23  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  3.3  Proposed Action and Alternatives  3.3.1 Geology and Soils  There are two general rock types in the UHBD area: the light‐colored granitic rocks of the Kodiak  Batholith, and the darker‐colored metamorphic rocks of the Kodiak Formation. (Refer to Photo B‐15,  Geologic Contact.)  The Kodiak Batholith forms the high mountain ridge between the Terror Lake reservoir and the  proposed UHBD area.  The proposed UHBD tunnel would cross directly through the Kodiak Batholith  ridge, and most of the tunnel excavation would be in the granitic rocks.  (Refer to Figure A‐5, Geologic  Map of Project Area.)  The granitic rocks of the Kodiak Batholith are strong and resistant to erosion.    The proposed UHBD tunnel would be inclined on a 1% slope from east to west, and is approximately 1.2  miles in length.  The maximum rock cover above the tunnel would be approximately 1,060 feet. The  upstream portal would be located immediately west of the D‐West diversion dam with the invert at  approximately 1,530 EL. The downstream portal would be located adjacent to the southwest end of the  Terror Lake reservoir with an invert at approximately 1,467 EL.  The tunnel size would be 12 feet in  diameter to convey up to 950 cfs of flow from the UHBD to the Terror Lake reservoir.    The area east of the mountain ridge is underlain by the somewhat weaker metamorphic rocks of the  Kodiak Formation. The Kodiak Formation rocks were originally fine‐grained sediments deposited  underwater that have been buried, compressed, densified, folded, and faulted during regional tectonic  deformation of Kodiak Island and intrusion of the Kodiak Batholith.  Exposures of these rocks in the  UHBD area vary from highly foliated and fractured shale and slate to more blocky, quartz and feldspar‐ rich meta‐sandstones, greywackes, and argillites. In the highly fractured meta‐sedimentary rocks,  fracture spacing appears to be as little as inches apart, while the more blocky rocks have fracture  spacing of about a foot or more.  Crown Mountain is a granite mountain ridge that forms the eastern edge of the Hidden Basin  watershed.  The contact between the granitic rocks of the Kodiak Batholith and Crown Mountain, and  the adjacent meta‐sediments of the Kodiak Formation can usually be identified by a change from light‐ colored to dark‐colored rocks, a change from steep to more gentle topography, and generally less  vegetative cover on the granitic rocks. The exact contact is often covered with soils and rocks which  have slid down the mountainside (colluvium), obscured by stream sediments (alluvium) or buried  beneath old glacial deposits (moraines).  The intrusion of the viscous and hot granitic magma of the  Kodiak Batholith and Crown Mountain severely heated and baked the adjacent Kodiak Formation meta‐ sedimentary rocks in a process called “aureole metamorphism.”  This process actually makes the rocks  denser and harder, although the fracture density may also increase compared to the same materials  outside of the baked zone. The width of the baked zone in the Kodiak Formation is reported to be from  less than a mile wide to over three miles wide regionally. Both the D‐West and D‐East dams and the  water conveyance between them would be either in or near this baked zone.  The proposed location for the D‐East diversion dam is a stream invert of 1,770 EL and the proposed  location for the D‐West diversion dam is a stream invert of 1,530 EL.  These stream channels consist  mostly of gravel and cobbles with occasional large boulders.  The channel banks consist of occasional  rock outcrops, gravel, cobbles and boulders.  Above the banks, the channel side slopes varied, some  with tundra vegetation (Lachel, 2015).  (Refer to Photos B‐4 and B‐5, D‐East Area.)  The proposed access road alignment would extend approximately four miles through the Kodiak  Formation, from the existing Project access road towards the D‐West and D‐East diversion dam sites.   Surface features range from rugged, mountainous terrain to wetlands. (Refer to photos in Appendix B.)    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 24

Stormwater Permit, and CWA 404 Wetland Permit Authorizations.    As the sole owner and operator of the Project, KEA would be responsible for the overall management of  the UHBD construction process.  KEA would provide an Environmental Compliance Monitor (ECM)  during construction to serve as the primary contact for communications among KEA and interested  entities, including the federal and state resource agencies and other entities as required. The ECM  would be periodically onsite during construction, and be available as needed to communicate with KEA  staff and contractor personnel regarding any identified issues. A description of the duties and authority  of the ECM is provided in Appendix E.   Protection and avoidance measures relating to erosion and sedimentation control are also specifically  addressed in KEA’s Contract Terms and Conditions document provided in Appendix E.     3.3.1.2 Record of Agency Consultation  This section will be completed in the Final PDEA.     3.3.2 Water Use and Quality  The total drainage area of the entire Hidden Basin watershed is 24.86 square miles.  The total drainage  area of the West Fork portion of Hidden Basin Creek is 11.76 square miles, and the proposed UHBD area  in the upper reaches of that West Fork is only 3.82 square miles.  The UHBD would divert 15% of the  overall Hidden Basin watershed drainage area.  (Refer to Figure A‐7, UHBD Water Diversion; Figure A‐8,  Hidden Basin Watershed.)  The upper catchment area of the Hidden Basin watershed is estimated to drain approximately 30,000  acre‐feet of snow melt and rain.  The UHBD proposal is to divert that surface water resource westward  through a mountain ridge tunnel toward the Project’s Terror Lake reservoir for hydropower generation.   The D‐West diversion dam catchment is estimated to provide approximately two‐thirds of the total  available water resources, and the D‐East diversion dam catchment would provide the remaining one‐ third.  The maximum capacity of the conveyance pipe connecting the D‐East diversion dam to the D‐ West diversion would be approximately 250 cfs, and the combined total diversion capacity of the  subterranean diversion tunnel connecting the D‐West diversion dam to the Terror Lake reservoir would  be approximately 950 cfs.  Surface water flow that exceeds the maximum capacity of the UHBD  conveyance pipe and tunnel would be spilled downstream over the diversion dam spillways into the  West Fork of Hidden Basin Creek.    Despite the 2,500 EL change in the watershed topography, diverting water from the upper reaches of  the Hidden Basin Creek would have no effect on surface water temperatures in the lower anadromous  reach of Hidden Basin Creek downstream.  Surface waters flowing in the lower mainstem of Hidden  Basin Creek are actually cooler than the surface waters flowing in the upper watershed area because the    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 25  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  mainstem of Hidden Basin Creek is fed primarily by groundwater, except during peak snowmelt and  large precipitation events.  Groundwater upwelling occurs downstream of the confluence of the West,  Middle and East Forks of Hidden Basin Creek.  Stream temperatures in the proximity of groundwater  upwelling zones are typically cooler than adjacent surface water and exhibit less fluctuation over a 24‐ hour period.  Detailed information on water temperatures measured at gauging stations along Hidden  Basin Creek is included in ERM’s report, Hidden Basin Creek April 2013 – October 2014 Temperature  Analysis Report, Supplement to the Hydrology and Fisheries Technical Report, June 2015 which is  provided in Appendix C.    The results of ERM’s temperature analysis are consistent with the results of the Project’s post‐licensing  study that examined the effects of the Project’s operation on the surface and intragravel water  temperature of the Kizhuyak River. A report assessing effects from construction and operation of the  Project on the temperature and streamflow (Trihey and Associates, 1992) stated that:   “For all practical purposes, project effects on intragravel water temperatures are the same as  project effects on surface water temperatures.   There are small seasonal differences between the pre‐ and post‐project surface water  temperature near the USGS gaging stations on both [Terror and Kizhuyak] rivers.   In the Kizhuyak River, post‐project water temperatures during summer are generally about one  degree C cooler than pre‐project temperatures.  There is a lesser difference between pre‐and  post‐project stream temperatures during the winter months.   Winter stream temperatures have changed little in the lower 1.5 miles of the Terror and  Kizhuyak rivers where the greatest amount of spawning activity has traditionally occurred.”  KEA operates three other diversion systems at the Project, and these three diversions have not resulted  in adverse effects in water quality downstream.  Post‐licensing studies of the Project indicated that  water quality parameters on the Terror and Kizhuyak Rivers are essentially unchanged from pre‐project  conditions.  Nutrient and sediment levels remained low and dissolved oxygen remained at or above  saturation.  Water quality problems that arise are temporary and typically associated with natural  events such as storm flooding (FERC, 2004).  The proposed UHBD would not involve any changes to Terror Lake, the main reservoir for the Project.   With the Terror Lake dam and spillway unchanged, the Project’s gross storage capacity and usable  storage capacity provided by the Terror Lake reservoir remains unchanged.  Terror Lake’s minimum lake  level elevation is 1,250 feet.  Maximum lake level elevation is 1,420 feet, which is the elevation of the  Terror Lake dam spillway.  The current volume of the Terror Lake reservoir is adequate to utilize the  additional inflows provided by the proposed UHBD under future projections of electrical load demand.   The Project has no license‐mandated lake level elevation rule curve.  The Project’s lake levels would  continue to be managed to ensure compliance with its Terror River instream flow requirements as per  FERC License Article 43.

As a requirement for all contractor work conducted at the Project site, KEA employs standard Contract  Terms and Conditions.  Protection and avoidance measures relating to erosion and sedimentation  control and protection of aquatic resources are included in this document.  A copy of the KEA Contract  Terms and Conditions document is provided in Appendix E.

Prevention, Control, and Countermeasures (SPCC) Plan for the Project.  Separate SPCC Plans specific to  any additional oil containers temporarily brought on‐site for UHBD construction would be required to be  prepared by the contractor, as is specified in the Contract Terms and Conditions document.       3.3.2.2 Record of Agency Consultation  ERM is currently engaged in a surface water stream gauging study in the Hidden Basin watershed.  This  stream gauging activity is authorized under DNR Land Use Permit No. LAS 29042 and ADF&G Fish Habitat  Permit FH 13‐II‐0038 (included in Appendix D – Approvals and Documented Compliance with Federal  Statutes).  KEA will continue to comply with the terms and conditions of these permits.    On April 10, 2015, KEA consulted with DNR Division of Land, Mining, and Water, Land Section and Water  Section staff regarding the process and application for water rights needed for the proposed UHBD.  KEA  received guidance from DNR staff regarding the process and the application, and on May 5, 2015, filed  an Application for Water Rights as per AS 46.15 for approximately 45,000 acre‐feet of surface water to  be diverted by the UHBD to the existing Terror Lake reservoir.  DNR advised KEA to request rights for an  amount of water greater than the amount of water estimated to be diverted because the quantity of  water can be easily adjusted down during the final water rights appropriations process, but it cannot be  easily adjusted up.  Therefore, KEA requested 45,000 acre‐feet of water as a conservative buffer to the  30,000 acre‐feet of water estimated to be available at the proposed UHBD. A copy of the Application for  Water Rights is provided in Appendix D.       Certification pursuant to CWA Section 401 is required as per FERC regulation 18 CFR 4.38(a)(1).  ADEC is  the lead agency for purposes of 401 Water Quality Certifications (WQC) for hydro projects pursuant to  the CWA; however, ADEC typically waives the requirement for the WQC for the type of action KEA is  proposing with the UHBD.  On May 20, 2015, KEA submitted a request to ADEC Division of Water,  Stormwater and Wetlands Program to provide a statement regarding the WQC.  On June 3, 2015, ADEC  issued a letter stating:

Wetlands in the vicinity of the proposed UHBD consist of palustrine emergent or scrub shrub wetlands  characterized by herbaceous vegetation and low or dwarf shrubs; depression bogs and marshes along  creek areas and riverine intermittent stream bottom; riverine upper perennial unconsolidated bottom;  and ponds.  The riverine water channel types are either deep incised canyon channels, alpine rivulets, or  braided gravel bed streams.  Ponds are typically very fine sand or silt substrate, many of which are  periodically dry (ERM, 2014).    The construction of the proposed UHBD will involve the filling of wetlands located in the vicinity of the

On April 29, 2015, KEA consulted with USACE staff in the Alaska Division, Kenai Field Office regarding the  applicable CWA 404 permitting requirements and application process for the proposed UHBD. KEA  received guidance from USACE staff regarding the process and the application and determined that  additional information is required to delineate the area of affected wetlands before an application may  be filed.  KEA intends to gather the necessary information and file a CWA 404 permit application with  the USACE in late 2016.    This section will be further completed in the Final PDEA.  3.3.4 Fishery Resources  No fish have been observed in the proposed UHBD area.  The diversion dams, tunnel, and access road  would be sited in the upland area above two major waterfalls that serve as fish passage barriers.  There  are no fish in the Terror Lake reservoir.  Both the UHBD and Terror Lake reservoir are located in upland  mountainous areas above major waterfalls that serves as a fish passage barriers.   The three‐mile long mainstem section of Hidden Basin Creek is listed as Stream No 259‐41‐10077 in the  ADF&G Catalog of Waters Important for the Spawning, Rearing or Migration of Anadromous Fishes  (AWC).  This reach of the Hidden Basin Creek mainstem is known to support chum salmon  (Oncorhynchus keta), pink salmon (Oncorhynchus gorbuscha), and Dolly Varden (Salvelinus malma). In  2014, minnow trapping associated with KEA’s recent research efforts confirmed coho salmon  (Oncorhynchus kisutch) was another anadromous fish species inhabiting the drainage seasonally.  Coho  were not previously documented in the AWC for the mainstem of Hidden Basin Creek.    The upper limit of the anadromous reach is approximately three miles downstream of the proposed  UHBD area, below the two major waterfalls that separate the mainstem from the UHBD area.  The  mainstem of Hidden Basin Creek forms at a canyon mouth where the West Fork joins with a Middle Fork  and East Fork of Hidden Basin Creek.  This convergence area of the three major forks remains dry the  majority of the time due to downwelling of surface waters to subsurface flow underneath the porous  alluvial substrate.  (Refer to Photo B‐20, Mainstem of Hidden Basin Creek.) Fish distribution is limited  spatially and temporally to intermittent, disconnected pools located on the mainstem of Hidden Basin  Creek, approximately one mile downstream from the confluence of the West, Middle and East Forks.    While renowned for their homing ability, salmon are also highly opportunistic and capable of exploiting  marginal or newly available habitat for their various life stages. The fact that portions of the mainstem  of Hidden Basin Creek experience discontinuous flow during late summer in some years suggests adult  pink and chum salmon (and potentially coho salmon) make use of the system opportunistically for  spawning under suitable flow conditions. Based on the prevailing gradient and substrate, most, if not all,  of this opportunistic spawning likely occurs in the mainstem. Although the West, Middle and East Forks  of Hidden Basin Creek have continuous flow, it is unlikely salmon spawn in them due to the steep  gradient, large boulder substrate and presence of waterfalls a short distance upstream from the  confluence with the mainstem. Spawning may occur at the mouth of the unnamed tributaries entering  the mainstem, but the substrate size and presence of barriers upstream on these tributaries is unknown  at this time. Fish occupying pools in the mainstem of Hidden Basin Creek that are seasonally dewatered  are not likely to survive the winter unless the pool has sufficient depth and food resources.     FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 29  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  The anadromous and resident fish found in the Hidden Basin Creek mainstem have likely adapted to the  stochastic nature of the surface water flows.  Fish habitat in the dry stream channel of the mainstem is  limited spatially and temporally.  During storm events or periods of high run‐off, fish may access the  otherwise dry reaches of the Hidden Basin Creek mainstem opportunistically but are likely to be trapped  in pools with limited resources such as dissolved oxygen or food, making them more vulnerable to  disease, competition, and predation.    The longitudinal movement of anadromous and resident fish in the mainstem of Hidden Basin Creek is  largely restricted to the stream reaches with available surface water.  The last two miles of Hidden Basin  Creek appears to maintain surface water connectivity to the marine tidewaters of Hidden Basin Lagoon.   Water diversions at the UHBD are not likely to impact available fish habitat in this lower reach of the  watershed.  The UHBD comprises only 15 percent of the overall Hidden Basin watershed area which is a  small portion of the surface water reaching the last two miles of the creek.    A small, isolated population of resident Dolly Varden has been observed in small numbers in the  meadow area located between the two large waterfalls on the West Fork of Hidden Basin Creek.  Adults  collected at this location in 2014 were relative small in size (150 millimeters). Resident Dolly Varden are  well known to persist in waters above barriers similar to the large waterfall in the West Fork of Hidden  Basin Creek.  Throughout their range, Dolly Varden are often the only species present above fish  migration barriers and likely benefit from the absence of competition for resources.4     3.3.4.1 Resource Protection Measures  KEA employs standard Contract Terms and Conditions to advise them on specific environmental  protection requirements, including terrestrial resource protection measures, while on Project lands.   Contractor personnel are not allowed to use the Project area for recreational purposes, such as hiking,  hunting, or fishing.  Contractor personnel are to confine their activities to the Project area relevant to  the construction of the UHBD.  Protection and avoidance measures relating to aquatic resources are also  specifically addressed.    As the sole owner and operator of the Project, KEA would be responsible for the overall management of  the UHBD construction process.  KEA would provide an ECM during installation to serve as the primary  contact for communications among KEA and interested entities, including the federal and state resource  agencies and other entities as required. The ECM would be periodically onsite during construction, and  be available as needed to communicate with KEA staff and contractor personnel regarding any identified  issues. A description of the duties and authority of the ECM is provided in Appendix E.      3.3.4.2 Record of Agency Consultation  ERM is currently engaged in a surface water stream gaging study in the Hidden Basin watershed.  This  stream gaging activity is authorized under DNR Land Use Permit No. LAS 29042 and ADF&G Fish Habitat  Permit FH 13‐II‐0038.  KEA will continue to comply with the terms and conditions of these permits.    ERM conducted fish presence, absence and distribution surveys along the West Fork and mainstem of  Hidden Basin Creek from the alpine headwaters to the lower mainstem reach.  The 2014 fish collection  activities were authorized under ADF&G Fish Resource Permit No. SF2014‐153.  KEA and ERM fulfilled all  terms and conditions of this permit, including providing ERM’s report, Hidden Basin Creek Hydrology and  4 The above text is primarily excerpted from ERM’s report, Hidden Basin Creek Hydrology and Fisheries Report, Technical Report  February 2015 which is provided in Appendix C.

Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  Fisheries Report, Technical Report February 2015 to ADF&G on February 27, 2015 which detailed the  results of the fish presence, absence and distribution survey.  KEA also nominated the addition of  juvenile coho salmon to Stream No. 259‐41‐10077, Hidden Basin Creek on Kodiak Island due to  observations of its presence in the lower reaches of Hidden Basin Creek during the 2014 study.    As a follow‐up to the 2014 fish presence, absence and distribution survey, ERM will conduct additional  presence, absence and distribution surveys of resident Dolly Varden in the upper reaches of the West  Fork of Hidden Basin Creek.  Fish collection activities associated with this study are authorized under  ADF&G Fish Resource Permit No. SF2015‐145.  KEA and ERM will continue to comply with the terms and  conditions of this ADF&G permit.    On April 1, 2015, KEA met with ADF&G staff in a pre‐filing meeting to discuss KEA’s intention to develop  the UHBD, and to discuss the three‐stage consultation process involved with the Application for Non‐ Capacity Amendment to FERC License No. 2743.    The ERM report, Hidden Basin Creek Hydrology and Fisheries Report, Technical Report February 2015  was provided to NMFS on March 12, 2015.    This section will be further completed in the Final PDEA.    3.3.5 Terrestrial Resources  Six terrestrial mammal species are native to Kodiak Island, or have colonized it since the last glacial  period (5,000 to 10,000 years ago). They are the Kodiak brown bear (Ursus arctos middendorfi), ermine  (Mustela erminea), river otter (Lutra canadensis), red fox (Vulpes vulpes), tundra vole (Mifrotus  oeconomus), and little brown bat (Myotis lucifugus).  All of these species occur in the Terror Lake  Hydroelectric Project area (FERC, 1981).   The primary mammal species of concern is the Kodiak brown bear.  Kodiak’s most well‐known species  appears to be distributed throughout the Island, and generally emerges from denning during the month  of May.  Breeding occurs in the period following emergence and generally ends by late June. Around  mid‐July, bears disperse from their alpine feeding range and move down to the lower elevations of the  Island’s river valleys to feed on fish.  Denning occurs in mid‐November, and the lower Terror River Valley  includes some of the best denning habitat (FERC, 1981).    ADF&G initiated a bear research program in 1982 concurrent with the construction of the Project.  The  primary objective of the bear research program was to document bear activities in the Terror, Kizhuyak,  and Elbow Creek drainages during and immediately after construction.  Results of intensive aerial  surveys conducted in 1987 and 1997 yielded density estimates of 234 independent bears (adults or  subadults) per 1,000 square kilometer (or 0.6 bears per square mile), and 276 independent bears per  1,000 square kilometer (or 0.7 bears per square mile), respectively.  The ADF&G investigation concluded  that KEA’s Project construction had little adverse impact on the local bear population.  It also noted that  as long as salmon resources were conserved, standard bear safety practices were followed, and access  along the Project access roads were carefully managed, operation of the Project was not anticipated to  harm bears (Van Daele, 2010).    Other mammal species have been imported accidentally or purposefully to the Island by man.    Sitka black‐tailed deer (Odocoileus hemionus sitkensis) was first introduced to Kodiak Island in 1934 and  are abundant throughout the Project area. The deer make vertical migration from sea level to alpine  areas in response to climatic conditions and the availability of food.  As fall arrives, the deer generally  migrate from the high elevations to feed on remaining succulent vegetation at lower elevations.  Deer  winter in the lower river drainages, generally below 500 EL (FERC, 1981).    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 31  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  Between the period 1929 to 1931, 23 beavers (Castor canadensis) were introduced to the Island and  released to lakes and streams.  Beaver can be found in habitat throughout the Island, including the  Terror and Kizhuyak river drainages.  Watchout Creek, in the lower Kizhuyak drainage, contains the most  significant sign of beaver habitation (FERC, 1981).  Kodiak Island supports a diversity of waterfowl as well as pelagic and shore birds.  Although no major  waterfowl production areas occur in the Project area, Kodiak Island’s river deltas provide suitable  habitat for numerous bird species. Project personnel report that bald eagles (Haliaeetus leucocephalus)  are observed year‐round in the Terror Lake Hydroelectric Project area, and they occasionally forage in  the Kizhuyak River in late July through September, when pink salmon are present.    3.3.5.1 Resource Protection Measures  KEA employs standard Contract Terms and Conditions to advise contractor personnel on specific  environmental protection requirements, including terrestrial resource protection measures, while on  Project lands.  Contractor personnel are not allowed to use the Project area for recreational purposes,  such as hiking, hunting, or fishing.  Contractor personnel are to confine their activities to the Project  area relevant to the construction of the UHBD.  Contactors may not bring firearms to the Project site,  and there is no motorized wheeled access authorized on Project lands other than official use vehicles.    Encounters with wildlife may occur in the Project area; however, KEA’s Terms and Conditions clearly  stipulate that animals are not to be harmed in any way.  All eagles, their eggs, and nests are protected  from disturbance.  No vehicles or equipment may interfere with beaver dams.    Contractor personnel are required to participate in a Bear Safety Orientation provided by KEA to  mitigate the possibility of conflict between personnel and a bear.  In accordance with KEA’s Bear Safety  Program, no food shall be left outside unattended, garbage handling will be done by incineration, and  there is no feeding of wildlife.  A bear incident reporting form is to be completed upon any significant  and abnormal encounter with a bear in the Project area, which is then forwarded to the ECM for ADF&G  notification.    As the sole owner and operator of the Project, KEA would be responsible for the overall management of  the UHBD construction process.  KEA would provide an ECM during installation to serve as the primary  contact for communications among KEA and interested entities, including the federal and state resource

3.3.5.2 Record of Agency Consultation  This section will be completed in the Final PDEA.      3.3.6 Threatened and Endangered Species   Based on consultation with the USFWS, there are no listed, proposed, or candidate species under the  ESA or their designated critical habitat identified to occur within the vicinity of the proposed UHBD.   Likewise, based on consultation with the NMFS, there are no species under NMFS jurisdiction and listed  as endangered or threatened under the ESA that are known or suspected to occur in the proposed  UHBD area, nor is there designated critical habitat for any such species in the proposed UHBD area.    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 32  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015    3.3.6.1 Resource Protection Measures  Due to the lack of use of the UHBD area by ESA listed, proposed, or candidate species, there are no  proposed measures specific to ESA.  Refer to discussion of other resources for protection and avoidance  measures associated with wildlife protection.      3.3.6.2 Record of Agency Consultation  On March 12, 2015, KEA submitted Requests to be Designated Non‐Federal Representative pursuant to  Section 7 of the ESA to consult with the USFWS and NMFS regarding any listed and candidate species.   On April 17, 2015, FERC issued a letter to USFWS and NMFS informing the agencies of KEA’s designation  as their non‐federal representative for the purpose of conducting informal consultation pursuant to  regulation 50 CFR 402.08 implementing Section 7 of the ESA.  On April 28, 2015, KEA requested species  lists from the USFWS and NMFS.    On June 1, 2015, USFWS staff directed KEA to utilize its automated Information for Planning and  Conservation (IPaC) online system (http://ecos.fws.gov/ipac/) for attaining information on federally  endangered or threatened plant and animal species, as well as plant and animal species of concern that  are known or suspected to occur in the UHBD area.  The automated IPaC system provided KEA with a  report that there are no listed species or designated critical habitat in the proposed UHBD planning  area.  Appendix D includes a copy of KEA’s species request letter to USFWS along with the USFWS IPaC  automated response report.    On June 1, 2015, KEA also received an e‐mail from the NMFS stating that none of the listed species  under the NMFS’ jurisdiction would be found in the proposed UHBD area.  The e‐mail also stated that  the lack of ESA listed species in the area precludes the need to consult informally with NMFS under  Section 7 of the ESA for development of KEA's proposed UHBD as part of the FERC‐licensed Project.   Appendix D includes a copy of KEA’s species request letter to NMFS along with their e‐mail response.    On June 9, 2015, copies of the findings and correspondence related to Section 7 ESA consultation were  filed with the FERC under separate cover.    3.3.7 Cultural Resources   During the Project’s original FERC licensing proceeding, KEA conducted reconnaissance archeological  surveys and test excavations within the proposed Project area of potential effect.  The reconnaissance  surveys at the then‐planned location of the dock/jetty and access road from Kizhuyak Bay to the  powerhouse resulted in discovery of two prehistoric sites (Righter, 1979).  Further test excavations at  KOD‐138 showed it to be a severely eroded, small site covering less than 100 square meters, and with  shallow cultural deposits.  Test excavations at KOD‐190 showed it to be a larger site spread over a 675  square meter area on an outcrop 6 meters above sea level.  Surface indications of ten housepits were  present, as well as indications of a late Kachemak Period occupation, 100 BC to AD 1100, and a later  Koniag occupation, AD 1100 to ca. 1760.  Both sites were interpreted as seasonally occupied fish camps  (Righter and Jordan, 1980).  Test excavations and analysis recommended that site KOD‐138 was not  eligible for listing on the National Register of Historic Places (NRHP).  Site KOD‐190, a stratified, multi‐ component prehistoric site, was recommended by investigators as eligible for the NRHP.    KEA, SHPO, Western Region of the Advisory Council on Historic Preservation (ACHP), and FERC  concurred with the recommendations and a mitigation plan for the sites located along Kizhuyak Bay.    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 33  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  KEA implemented mitigation measures, including moving the planned access road further away from the  sites, relocating the dock/jetty, posting notices to contractor personnel regarding cultural resources, and  periodic monitoring of the site conditions.  The archeological sites are located outside of the Project  boundary on lands owned by the Afognak Native Corporation (ANC).     The cultural resource surveys conducted during the Project’s original licensing studies did not locate any  cultural resources in the vicinity of Terror Lake or Hidden Basin.  The UHBD would be constructed in an  interior location on Kodiak Island at a high elevation, which was difficult to access from coast prior to  the Project’s road construction.  There are few resources to attract human use of this remote area, and  salmon cannot reach the area.    Northern Land Use Research, Inc. (NLUR) prepared the report, Review of Cultural Resources in Vicinity of  Kodiak Electric Association Terror Lake Project – FERC No. 2743 Upper Hidden Basin Diversion Project at  the request of KEA.  The report describes the locations of the protected sites, presents an overview of  the proposed UHBD, and makes recommendations for measures appropriate to the proposed action.   The report was provided to SHPO on May 1, 2015 for their review and comment.  The Alaska SHPO  reviewed NLUR’s report and issued a letter dated May 28, 2015 with concurrence that a finding of no  historic properties affected is appropriate for the proposed license amendment for the UHBD.      3.3.7.1 Resource Protection Measures   As recommended in the NLUR report and reiterated by the Alaska SHPO in a letter dated May 28, 2015,  KEA agrees that (1) no cultural resource survey is required for the UHBD area due to the low probability  of encountering cultural resources based on the Project location and the negative findings from previous  research; (2) the existing mitigation measures will remain in place and be updated as necessary in FERC  licensing for the UHBD; (3) KEA will continue using the existing contract language and procedures  regarding the inadvertent discovery of human remains or cultural resources during construction; (4) KEA  will continue to provide contractor personnel training on cultural resources and human remains and the  protections given under state and federal laws; (5) KEA, Alutiiq Museum and Archaeological Repository,  and ANC continue the successful archaeological stewardship monitoring of cultural resource sites;  and  (6) KEA initiate Section 106 consultation with the Alaska SHPO by providing this report and a summary of  measures to be taken during the construction of the UHBD.    KEA will continue its contractor personnel education and cultural resource awareness program.  A copy  of the KEA Contract Terms and Conditions document is provided in Appendix E.  KEA executed a Memorandum of Understanding (MOU) with ANC and the Alutiiq Museum and  Archaeological Repository to conduct the required period monitoring of site KOD‐190. The MOU  provides for periodic monitoring and reporting on the status of KOD‐190 by a qualified archaeologist,  consultations with ANC, and annual reporting on the monitoring program. The MOU is an innovative,  collaborative approach to cultural resource stewardship.  A copy of the MOU is included in Appendix E.  These mitigation measures provide adequate protection to KOD‐190.  Construction and operation  activities associated with the proposed UHBD would not take place anywhere near the KOD‐190 site.   KEA policy, procedures, and training prevent contractor personnel from approaching anywhere near the  site.  Additionally, ongoing periodic monitoring of the site condition would verify that these measures  are working to protect site KOD‐190.  Implementation of these measures would assure that no historic  properties will be adversely affected by UHBD.

Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  3.3.7.2 Record of Agency Consultation  On March 12, 2015, KEA submitted Requests to be Designated Non‐Federal Representative pursuant to  Section 106 of the NHPA to consult with the Alaska SHPO regarding historical properties potentially  affected by the proposed UHBD.  On April 17, 2015, FERC issued a letter to SHPO informing the agency of  KEA’s designation as their non‐federal representative for the purpose of conducting informal consultation  pursuant to the regulation 36 CFR 800.2(c)(4) implementing section 106 of the NHPA.  On May 1, 2015, the NLUR report, Review of Cultural Resources in Vicinity of Kodiak Electric Association  Terror Lake Project – FERC No. 2743 Upper Hidden Basin Diversion Project was transmitted to the SHPO  pursuant to Section 106 of the NHPA as Privileged Information.  SHPO responded in a letter dated May  28, 2015 with agreement that a finding of no historic properties affected is appropriate for the proposed  license amendment for the UHBD.  A copy of this letter is provided in Appendix D.  On June 9, 2015,  copies of the NLUR report and SHPO letter were filed with the FERC under separate cover as Privileged  Information.      3.3.8 Land Use   The UHBD area is located 30 miles west of the City. There are no towns located within 15 miles of the  Project, or any other developments in the Terror or Kizhuyak watersheds. The only activity in the vicinity  of the Project are KEA staff who operate and maintain the Project equipment and facilities.  According to  the KIB GIS records, there are seven privately owned lots equipped with tax‐assessed buildings along the  southwestern shores of Hidden Basin Lagoon located at the mouth of Ugak Bay.  This area is over six  miles south of the proposed UHBD area, on the shores of marine tidewaters to the west of the Hidden  Basin Creek delta outlet. (Refer to Photo B‐24, Aerial View of Southwestern Shore of Hidden Basin  Lagoon.)  The Project occupies land owned by ANC, KEA, KIB, State of Alaska, and Kodiak National Wildlife Refuge.   (Refer to Figure A‐6, Land Ownership Map.)  ANC owns lands occupied by the Project’s existing  dock/jetty and portions of the Project’s existing access road.  KEA is authorized to access these areas  with an easement lease granted by ANC for a term of 50 years (April 2, 1982 – April 2, 2032), extending  beyond the November 1, 2031, expiration date of the FERC license. This easement lease was filed with  FERC on April 24, 1986.  KEA and KIB own lands occupied by the Project’s powerhouse facilities.  KEA is  authorized to access KIB lands in accordance with the agreement, Authorization to Enter on Kodiak  Island Borough Land to Design, Construct and Maintain the Terror Lake Hydroelectric Project signed on  March 26, 1982.  The State of Alaska owns the submerged lands at the Project’s existing dock/jetty, and  KEA is authorized to use those submerged lands with DNR lease agreement ADL No. 206462.  The  remaining portion of the Project east of the Terror watershed (with exception of 136 acres for the  portion of the transmission line corridor near the City of Kodiak), is owned by the State of Alaska.  KEA is  authorized to occupy these State lands with DNR lease agreement ADL No. 204024.    The Project’s licensed boundary currently occupies 4,282 acres of federal lands.  Of that total amount,  136 acres of the Project boundary encompass lands occupied by the Project’s transmission line  connecting Project power to the City of Kodiak.  The other 4,146 acres of the federal land within the  Project boundary encompass the Terror Lake reservoir and western portions of the Project access road  and tunnel.    The majority of the proposed UHBD area is located on lands owned by the State of Alaska, managed by  the DNR.  By necessity of connecting the UHBD water resources to the existing Terror Lake reservoir,  some of the new UHBD would need to be constructed on federal land already occupied by the Project  and administered by the Kodiak National Wildlife Refuge.  A portion of the proposed UHBD tunnel    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 35  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  corridor would need to occupy 1.9 additional acres of federal land administered by the Kodiak National  Wildlife Refuge outside the current Project boundary.  This 1.9 acre corridor of expanded Project  boundary on federal land would encompass a subterranean tunnel, completely underneath a mountain  ridge.    A detailed map of the proposed revisions to the FERC‐licensed Project boundary, including the location  of the 1.9 additional acres of federal land, are provided in Draft Exhibit G – Project Map.      3.3.8.1 Resource Protection Measures  KEA intends to acquire all necessary land use authorizations for the proposed UHBD activities prior to  filing the Final Amendment Application.  KEA will comply with the terms and conditions of these land  use authorizations.      As a requirement for all contractor work conducted at the Project site, KEA employs standard Contract  Terms and Conditions to advise them that they shall comply with all environmental protection  requirements while on Project Lands. A copy of the KEA Contract Terms and Conditions document is  provided in Appendix E.     3.3.8.2 Record of Agency Consultation   ERM is currently engaged in a surface water stream gaging study in the Hidden Basin watershed.  This  stream gaging activity is authorized under DNR Land Use Permit No. LAS 29042.  KEA will continue to  comply with the terms and conditions of this Land Use Permit.  On April 10, 2015, KEA consulted with DNR Division of Land, Mining, and Water, Land Section and Water  Section staff regarding the process and application for land access needed for the proposed UHBD.  KEA  received guidance from DNR staff regarding the process and the application, and on April 14, 2015, filed  an Application for Easement as per AS 38.05.850 for the portions of the proposed Upper Hidden Basin  Diversion located on State land.  A copy of the Application for Easement is provided in Appendix D.       On April 22, 2015, KEA consulted with USFWS Kodiak National Wildlife Refuge staff regarding the  process for land access needed for conducting pre‐filing geotechnical studies and for constructing the  tunnel that would connecting the water resource of the proposed UHBD to the Terror Lake reservoir.      This section will be further completed in the Final PDEA.    3.3.9 Recreation and Aesthetic Resources  There is minimal recreational demand in the Project area due to difficult access and concerns over  minimizing brown bear and human conflicts.  Public use of the Project area is essentially non‐existent  because there are ample opportunities for recreation at other more accessible areas of Kodiak Island  (Refer to Figures A‐9, Recreation Sites Near Project; and Figure A‐10, Existing Recreation on Kodiak  Public Road System.)  FERC exempted the Project from filing the Hydropower Development Recreation Report, FERC Form 80,  because of the lack of recreational use at the Project.  Due to its low hazard potential and remote  location, KEA has also remained exempt from Emergency Action Plan requirements since its original  construction.      FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 36  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  3.3.9.1 Resource Protection Measures  For the rare instances that the public approaches the Project area, an informational kiosk and sign‐in  book are located at the entrance of the access road from the Kizhuyak Bay dock/jetty on lands owned by  the ANC.  The information presented at the kiosk was developed in consultation with ANC staff.    Public Safety devices utilized in the Project area consist of gates, signs, and fences.  These devices are  not specifically relevant to the UHBD area, but to the overall Project area.  A copy of the Project’s Public  Safety Plan, written in accordance with 18 CFR 12.4 and 18 CFR 12.42 is provided in Appendix E.     Due to the remote location of the Project and lack of public use, no aesthetic resource measures are  proposed.      3.3.9.2 Record of Agency Consultation   In correspondence dated June 17, 1997, FERC acknowledged that available information indicates there is  little or no potential for recreational use at the project. Therefore, in accordance with 18 CFR 8.11(c),  FERC has exempted KEA from further filing of the Form 80 for the above‐cited project, until further  order of the Commission.     3.3.10 Socioeconomic Resources    The City is the economic, transportation, and governmental center of the island archipelago area.  It is a  Home Rule City with an elected Mayor and Council, which employs a City Manager.  The City ranks  eighth in terms of population, in comparison to other boroughs and unified municipalities of Alaska. The  KIB is a second‐class borough incorporated September 24, 1963, and operates under a Manager form of  government with an elected Assembly.  Access to Kodiak Island is by air or water. Alaska Airlines and Ravn Air provide regular scheduled service.  Andrew Air, Island Air and Servant Air also provide scheduled air taxi flights to outlying communities,  and charter services are available.  Float plane facilities are also prevalent in Kodiak, as airport facilities  or landing strips throughout the archipelago are not widely available. The road system on the Island  follows the coastlines from Cape Chiniak and Narrow Cape north through the City of Kodiak to  Monashka Bay. There is no rail service. The Alaska Marine Highway System provides passenger, vehicle  and cargo ferry service connecting Kodiak to Alaska’s mainland road system.  Ferry transit from the City  to the nearest mainland ferry terminal in Homer, Alaska is typically eight hours in duration during calm  weather and smooth seas.    Marine terminals in Women’s Bay provide service to several freight carriers, freight forwarders and  consolidators, construction contractors, and the fishing fleet. The terminal has warehousing, yard storage,  and crane services.  The cost of shipping to Kodiak is a significant factor in the overall cost of living for the  region, and improving the affordability and reliability of shipping in Kodiak is essential to the region’s  economy.  Pier III is the primary cargo freight port facility for the Kodiak Island region with nearly every  commodity imported or exported from Kodiak Island’s communities’ passing across Pier III.  KEA has  partnered with the City to repower Pier III’s inefficient diesel‐powered crane with a new electric crane.  The older diesel‐powered crane was restricting the loading capabilities of Pier III to smaller specialized  vessels, and kept the region vulnerable to limited transportation options and inflated shipping costs. KEA’s  efforts to help modernize Kodiak’s regional port hub with a bigger, faster, more energy‐efficient electric  crane allows more local seafood products to be exported to the global market, and better food and  building materials to be brought into Kodiak’s remote island communities.      FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 37  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  The majority of the KIB population resides in the area directly within or adjacent to the City.  KEA  provides electricity to approximately 6,000 meters on Kodiak Island (Refer to Figure A‐2, KEA Service  Area.)  The availability of electric power generated primarily by KEA’s integrated hydro‐wind generation  system provides electric service at a cost that is buffered against the extreme swings in diesel fuel cost.   KEA’s load demand is growing because the community is developing new infrastructure based on KEA’s  renewably‐generated electricity as the local energy solution.  The direct benefit to the membership is  not only in fuel‐free, emission‐free renewable power, it is in the stable, predictable cost of electric  energy. While other utilities around the nation are struggling with rate increases, KEA provides stable, or  slightly lower, electric rates to its Cooperative membership.  The US median rate for electric revenue per  kWh sold from 2000 to 2013 has increased 49%, while KEA’s has seen a mere 1% increase. The US  Median electric revenue per kWh has increased 18.9% from 2007 to 2013, while KEA’s has decreased  10.4% during that same period (NRUCFC KRTA, 2007‐2013).  The economic benefits of KEA’s renewable  energy vision are substantially positive for the Kodiak community.   The Port of Kodiak is home to Alaska’s largest and most diversified fishing fleet and is constantly ranked  in the top three largest fishing ports in the US in terms of value landed.  It has more than 650 boat slips  and three commercial piers that can handle vessels up to 1,000 feet.  More than one‐third of the jobs in  Kodiak are directly related to the fishing industry, in either the harvesting or processing sectors.  There  are 789 active permit holders in the local commercial fisheries.  Landings to the Port of Kodiak in 2012  were 382 million pounds, with a wholesale value of $178.6 million.  Groundfish, primarily pollock and  cod, is the largest segment of Kodiak’s fisheries in terms of volume and wholesale value, accounting for  approximately 75% of the region’s commercial catch and 49% of the region’s total wholesale value.  Salmon is the next largest with about 29%; halibut at 17%; crab at 3%; and herring at 2%.  Kodiak’s  seafood processing plants employ approximately 3,226 people with a combined payroll of over $47  million.  The largest shoreside seafood processors include Trident, International Seafoods of Alaska,  Ocean Beauty, and North Pacific Seafoods.  Subsistence and sport fishing are also prevalent in the region  (Kodiak Chamber of Commerce, 2013).  The electricity required to process and freeze seafood products drives KEA’s electrical load demand.  Now that the local seafood processing industry is powered with KEA’s affordable and stably‐priced  electricity, Alaskan seafood companies are choosing Kodiak as their regional processing hub to expand  their operations.  KEA is pleased to support the growth of Kodiak’s primary commercial industry as these  expanded facilities bring more jobs and revenue into the local community.    Kodiak’s role as a major commercial fishing port and one of the nation’s largest producers of seafood is  complemented by it being a regional center for transportation, governmental offices, timber, and  tourism.  The local hospital ranks among the top employers, and the City, KIB, state, and federal  agencies also provide local employment.  Kodiak Island is also home to the nation’s largest US Coast  Guard (USCG) Base equipped with both aviation and maritime fleets. KEA is proud to assist the USCG in  their efforts to meet their federal facility renewable energy requirements. KEA allocates Renewable  Energy Credits to the membership, including the USCG Base without additional costs.  As a Cooperative,  KEA’s membership already owns the renewably‐powered electric grid and it is KEA’s honor to share all  of the value‐added benefits and renewable energy credits with the member owners it serves.    KEA’s goal is to continue using renewable wind and hydro energy resources for 95% of the community’s  electricity needs.  To illustrate how integrated the local community is in KEA’s vision statement, the  Kodiak Chamber of Commerce embarked on an Economic Development Project “salmon wind water”  branding campaign in 2011 to redefine sustainable seafood. The local salmon processors are proud to be  part of an electric grid that is embracing clean energy and moving away from reliance on fossil fuel‐ based power. In July 2010, a local fish processing plant in Kodiak also began marketing its product by  touting its connection to sustainable energy via Kodiak’s Pillar Mountain wind farm on its packaging.     FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 38  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  KEA’s success with implementing sustainable, renewable energy solutions has drawn the attention of  numerous media outlets that travel to Kodiak to learn how a small rural electric cooperative could make  such a huge difference in renewable energy and micro‐grid technology development.  Numerous  magazine and news articles have been written about KEA’s leadership and success in laying out a  strategy to move the local community away from fossil fuels and toward cost effective renewable  energy solutions.  KEA has been awarded the 2014 State Leadership in Clean Energy Award by the Clean  Energy States Alliance; the 2014 Clean Energy Innovator of the Year Award by the Renewable Energy  Alaska Project; the 2009 Wind Cooperative of the Year Award by the National Rural Electric Cooperative  Association and US Department of Energy; the 2009 Cornerstone Award by the Kodiak Chamber of  Commerce; and was a nominee for the Utility Scale Innovation 2013 Award from the Energy Storage  North America.   The proposed action would have no direct impact on local government revenues.  KEA is a rural electric  cooperative, and as a 501(c)12 not‐for‐profit organization, KEA is exempt from local, state, and federal  taxes.  Boosting the Project’s power production with additional water resources provided by the  proposed UHBD would, however, indirectly benefit the local governments by enhancing the Kodiak  economy as a whole with stable cost of renewable power and continuation of marketing opportunities  associated with renewable energy.  When the cost of power is more stable and predictable with  renewable sources of energy, KEA’s cooperative members, including the City and KIB, remain in a better  position to plan and budget for their power costs.  KEA’s renewable energy portfolio provides marketing  opportunities for Kodiak businesses that use KEA’s electricity to manufacture their products, and if these  new marketing campaigns result in increased business, then the proposed action could boost Kodiak’s  local government tax revenue.  Enhancing the existing Project with the UHBD would have a direct  positive effect on the community and future sustainability of Kodiak Island.   The proposed action would have no direct impact on local government expenditures.  There are no  municipal services, such as road, police, fire or medical services at the remotely located Project site.   Infrastructure support for temporary construction personnel already exists at the Project.  As the sole  owner and operator of the Project, KEA is responsible for maintaining and repairing the Project’s  infrastructure including the dock/jetty, access roads, buildings, utilities, and fire protection systems.  A  fully‐functioning single‐family home can house a small construction crew up to eight people.  For larger  sized construction crews up to 30 people, an additional contractor camp is available onsite with hook‐ ups for electricity, potable water, and sewer.  KEA staff and hired contractor personnel at the Project  site are responsible for conducting themselves in a safe and professional manner.  If a medical  emergency were to arise at the Project, flight evacuation to a hospital or other treatment facility would  be provided at KEA’s expense.  Construction of the UHBD is a temporary process that would not result in  a significant change to Kodiak’s population.  Once built, the UHBD would not require additional KEA staff  to operate at the existing Project.      3.3.10.1 Resource Protection Measures  As the sole owner and operator of the Project, KEA would be responsible for the overall management of

Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  4. Developmental Analysis  4.1 Power and Economic Benefits of the Project    The UHBD provides substantially positive benefits to the Kodiak community because the only other  available alternative for power generation is diesel fuel.  Economic benefits of the UHBD are therefore  determined by comparing the costs to produce the amount of power made available by the water  resources of the proposed UHBD versus diesel‐based generation.  Compared to the diesel alternative,  the net present value (NPV) for the UHBD is over $129 million.  Considering the relatively small size and  scope of the proposed project that level of benefit is highly material, and is a significant value for the  Kodiak community.   KEA proposes to have the UHBD operational by 2020.  KEA’s system load demand in 2020 is expected to  be 18 million kWh greater than KEA’s currently available hydropower and wind energy supply.   Therefore, without the additional water resources provided by the UHBD, the 18 million kWh of  additional load demand would require KEA to revert back to diesel‐generated power.  KEA’s diesel‐ generation efficiency is 14.2 kWh per gallon of diesel fuel.  KEA’s historical average cost of diesel fuel is  $3.14 per gallon.  In addition to the direct cost of diesel fuel, diesel engine maintenance costs average  4¢ per kWh.  KEA’s annual budget assumes a fuel and maintenance cost inflation rate of 3%.  Based on  these diesel generation efficiency rates and costs, the direct fuel costs for generating 18 million kWhs  without the UHBD is approximately $4.5 million, plus an additional $818,825 in diesel engine  maintenance cost.      Table 4‐1 Summary of UHBD Costs and Savings Incurred within First Year of Operation  Year 1 Costs Year 1 Savings

Total Cost in Year 1 $4,668,764 Total Savings in Year 1 $5,345,430  NET SAVINGS in Year 1 = $676,666      Even with the expenses of constructing this new diversion, including debt and maintenance, the first  year benefits of the UHBD would net $676,666 in savings.  While this is very positive, it is the lowest year  of net savings due to it being the lowest production needed from UHBD to supplement KEA’s growing  loads.  The annual cost‐saving benefits of hydropower continue to escalate from $676,666 in Year 1, to  $5.7 million in Year 5 of UHBD operation as KEA’s electrical load grows.  This is due to the hydropower  being basically a fixed‐cost asset while diesel fuel prices continue to inflate.  The expected continual  growth in savings provided by the UHBD is illustrated in Figure 4‐1.                  FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 41  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  Figure 4‐1 Annual Savings Provided by UHBD     UHBD’s project life is 50 years; however, based upon KEA’s experience with its financing institutions, it is  highly probable that the amortization period for financing the UHBD would be 30 years.  Therefore, the  economic projection is set at 30 years.  Even at that limited time frame, the simple payback will occur  before 15 years of operation has occurred.  There is very little operation and maintenance cost for the  UHBD as it is simply a water conveyance diversion.  It utilizes the Project’s existing Terror Lake reservoir,  main power tunnel, penstock, powerhouse, substation, and transmission line.   Figure 4‐2 illustrates the cumulative benefit of the UHBD in its lower and stable cost of power versus the  high cost of diesel power, which is the no‐action alternative.  By Year 15, the cost of diesel is three times  more expensive than the hydroelectric power made available by the water resources of UHBD.      Figure 4‐2 Cost of Power Comparison ‐ UHBD Hydropower vs. Diesel‐Based Generation   $0 $2,000,000

Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  The power and economic benefits provided by UHBD and the overall Project have a significant  cumulative positive effect over time.  Over the 30 year financing term, a total of 66,947,372 gallons of  diesel fuel are expected to be saved from the additional hydropower production made possible by the  water resources of the UHBD.  The direct savings from that avoided fuel cost are $380 million, plus the  additional $69 million in savings from avoided diesel engine maintenance cost.  Not only does the UHBD  supply stable‐cost power for the community for years to come, it supplies an extremely cost‐effective  source of power that becomes even more cost‐effective every year after its first year of operation.      4.1.1 Operation of Project with Upper Hidden Basin Diversion   A significant benefit of this UHBD is the simplicity of its operation.  It is a diversion that utilizes all  existing aspects of the Project with no moving parts.  In 1978, the original engineers of the Project  recommended this diversion as a future development as it was found to be the most economical means  of increasing hydropower production whenever the growth in power demand in Kodiak justified it  (Retherford, 1978).  The Project already has three other diversions:  Shotgun Creek Diversion, Falls Creek  Diversion, and Rolling Rock Creek Diversion.  KEA has 30 years of experience successfully operating and  maintaining these low maintenance features.    KEA is in full compliance with all requirements of Part 12 of the Commission’s dam safety regulations.   The Project has been operating for 30 years under the terms and conditions of the existing license.   During this time, Commission staff has conducted operational inspections focusing on the continued  safety of the structures, efficiency, and safety of operations, compliance with terms of the license and  proper maintenance.  In addition, the Project has been inspected and evaluated every 5 years by an  independent consultant; most recently in August 2010 with a consultant’s safety report filed on  December 10, 2010.  As a required part of the project development and review process for the proposed  UHBD, KEA will provide the final engineering design and associated construction quality control and  Project safety plans to the FERC PRO Division of Dam Safety and Inspections for their approval prior to  finalizing construction contracts.  The final engineering design and associated construction quality  control plans are expected to be ready for FERC PRO review in 2017.    With the exception of station service and transmission losses, all Project power is sold to KEA’s  Cooperative members.  The full contribution of the UHBD is expected to be fully utilized by 2025.    Refer to Section 2.1.3 for additional discussion of how the UHBD would be operated with the UHBD.  A  detailed analysis of how the additional inflows provided by the UBH diversion will be utilized by the  Project is also presented in Draft Exhibit B – Project Operation and Resource Utilization.     4.2 Comparison of Alternatives    4.2.1 KEA's Proposal  The UHBD will divert water from the upper reaches of the Hidden Basin watershed to the existing Terror  Lake reservoir for additional hydropower production at the existing Project powerhouse.  The UHBD  boosts KEA’s renewable energy supply by utilizing existing infrastructure and enhancing its potential for  annual energy generation.  The proposal would not change the authorized installed capacity of the  Project; however, the additional water resources added to Terror Lake from this diversion are expected  to increase average annual generation by an additional 33 million kilowatt‐hours.  KEA proposes to construct two new concrete face rockfill dams approximately 30 feet high and 250 feet  wide within an eastern and western tributary branch of the West Fork of Hidden Basin Creek,  approximately six miles upstream of Hidden Basin Lagoon and Ugak Bay on the eastern side of Kodiak    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 43  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  Island, Alaska.  Surface water from the diversion dam on the eastern tributary (D‐East) would flow  through a half‐mile long, five foot diameter underground pipe to the diversion dam on the western  tributary (D‐West).  From there, surface water from both diversion dams would flow by gravity through  a 1.2 mile long, 12 foot diameter tunnel through a mountain ridge to Terror Lake, the main reservoir for  the Project.  The proposed diversion dams would include broad crested weir sections that would provide  adequate spillway capacity during periods of heavy rain and snow melt in excess of the diversion’s  conveyance pipe and tunnel hydraulic capacity.  Any amount water flow that exceeds the capacity of the  UHBD conveyance pipe and tunnel would be spilled downstream over the diversion dam spillways into  the West Fork of Hidden Basin Creek.  The proposed UHBD would also include a four mile long spur road  off of an existing road to provide access for constructing and maintaining the new diversion.   The total cost of the project is estimated at $79,992,000.  KEA’s annual debt and maintenance for the  UHBD Project is $4,668,764, with the significant majority being the debt service.  Based on KEA’s 30‐year  operation of three other similar diversion structures already in operation at the Project, there is very  little annual maintenance required for the proposed UHBD.  Once the UHBD is built and fully utilized,  the annual savings will exceed $6.5 million.  The economic benefits provided by the UHBD for the  communities of Kodiak are significantly positive.    4.2.2 No‐Action Alternative  Under the no‐action alternative, the Commission would deny the proposed construction and operation  of the UHBD.  The Project would continue to operate under the conditions of the existing license.   Denial of the proposal would effectively close the door on KEA’s renewable energy innovations and  negate the substantial, community‐wide efforts to reduce consumption of fossil fuels.  The no‐action  alternative would impair the ability of KEA to provide a continuous supply of renewable energy to power  the community’s growing energy needs, thereby hindering the modernization of Kodiak’s infrastructure.   Denial of the UHBD proposal means that KEA must revert back to burning fossil fuels in its diesel units to  power its growing electrical load and expose its Cooperative members to the consequences of  increasing air emissions and high energy costs.      4.3 Cost of Environmental Measures   No environmental measure costs are proposed for the UHBD.    Construction and operation of the UHBD is not anticipated to result in significant environmental impact.  The purpose of the proposal is to divert a small portion of the watershed’s resources from the upper  reaches of the West Fork of Hidden Basin Creek for renewable energy production.  The UHBD would be  similar to existing diversion structures currently in operation at the Terror Lake Hydroelectric Project,  and for the past 30 years KEA has proven that it can successfully and responsibly construct and operate  these types of hydropower facility components in this environment without adverse effects.    The UHBD comprises only 15% of the overall Hidden Basin watershed size, and is located in an upper  alpine area where no fish have been observed.  The diversion of water from the upper portions of the  Hidden Basin watershed is not likely to have an impact on the anadromous habitat located three miles  downstream, below two major waterfall barriers.  No threatened or endangered species are found in  the proposed UHBD area.  There would be minimal change in the facility’s aesthetic appearance, and  there is essentially no public use in the Project vicinity.    Constructing the new diversion dams and access road will require structures to be placed within  tributary creeks and wetlands; however, this activity is routinely authorized under license and permit    FERC License Amendment Application ‐ Upper Hidden Basin Diversion    PDEA  – Page 44  Kodiak Electric Association, Inc.        Draft  Terror Lake Hydroelectric Project, FERC Project No. 2743       June 2015  conditions that specify best management practice requirements to minimize potential impacts to the  aquatic and terrestrial environments.  The minor impacts incurred by temporary construction activities  are far outweighed by the long‐term benefits associated with enhancing renewable energy  infrastructure with this hydropower diversion.      4.4 Greenhouse Gas Reduction   Diesel‐powered generation is a source of carbon dioxide (CO2) pollution that contributes to climate  change and ocean acidification.  The more gallons of diesel fuel KEA burns for electric power generation,  the more carbon pollution is introduced into the global atmosphere.  The purpose of constructing and  operating the UHBD is to reduce KEA’s consumption of diesel fuel.    KEA’s diesel‐generation efficiency is 14.2 kilowatt‐hours per gallon of diesel fuel, which means that the  amount of renewable energy provided by the proposed UHBD (33 million kWh) equates to 2.3 million  gallons of diesel fuel that otherwise would have to be burnt annually to generate an equivalent amount  of power with diesel‐fired power generators.  Based on the Environmental Protection Agency’s (EPA)  emission factor for CO2 as specified in 40 CFR 98.33, burning 2.3 million gallons of diesel fuel would  release 23,744 metric tons of GHG emissions to the atmosphere.  The additional hydropower production made possible by the water resources of the UHBD therefore  saves 23,744 metric tons of CO2 from being emitted to the atmosphere each year.  To help put that  amount of pollution into context, Kodiak would have to remove 4,999 passenger vehicles5 or more than  two‐thirds of all passenger vehicles registered in Kodiak6 off the road to achieve the same level of  carbon emission reduction.  The benefits of the proposed UHB are not just economical savings, it is a  reasonable approach to pollution prevention.      It is KEA's responsibility to supply reliable and affordable electricity to a community that prides itself on  living in harmony with its surrounding environment.  KEA’s grid is experiencing an increase in load  demand because the community is switching its source of energy from fossil fuels to locally‐ and  renewably‐generated electricity.  KEA strives to continue powering Kodiak’s future energy needs with  renewable energy.  The UHBD is the most cost‐effective and feasible approach for KEA to achieve its  vision:  Endeavor to maintain 95% of energy sales with cost effective renewable power   solutions for the future of our members and the community.   5 Based on EPA’s online greenhouse gas equivalency calculator, www.epa.gov/cleanenergy/energy‐resources/calculator.html.

The study quantified the cumulative volume of surface water available in the 2014 water year (WY) for the proposed Upper Hidden Basin Diversion Project. The Upper Hidden Basin Diversion Project would supplement the available water supply for the Terror Lake Hydroelectric Project by diverting surface water in the upper reaches of the HBC watershed and convey it to the existing Terror Lake reservoir. The study also quantified the volume of surface water at additional gage locations distributed longitudinally in Hidden Basin Creek (HBC) from the alpine headwaters near the proposed hydropower diversion area to the creek’s lowland mainstem approximately one mile (mi) from the marine environment. Lastly, the study documented the presence / absence of fish species longitudinally near the respective gage locations and relative to two waterfalls in Upper HBC serving as potential barriers to upstream fish migration. Prior to this study effort, little was known about the hydrology, fish habitat, and fish distribution in HBC. The study succeeded in improving the local knowledge and understanding of the HBC hydrology and fish distribution in the drainage. Four stream gaging stations were established longitudinally in HBC from the headwaters to the mainstem reach upstream of the confluence with the marine environment. Gage D-West is located on the main reach of Upper HBC (West Fork Upper HBC) near an initially proposed location for the D-West Diversion dam. This reach of stream is characterized by a step-pool high gradient slope, steep bedrock banks, and large boulder/bedrock substrate. Gage D-East is located on a tributary to the main reach of Upper HBC (East Fork Upper HBC) approximately 650 feet (ft) in elevation below the D-East Diversion dam. The stream reach where D-East Diversion is located is characterized by a step-pool high gradient slope, steep undercut banks with overhanging vegetation, and large boulder/bedrock substrate. Gages 2 and 3, located downstream in the West Fork of HBC and the mainstem, respectively, were established to quantify the proportion of water remaining in lower HBC to assess the potential impact of diverting water at the Upper Hidden Basin Diversion Project to Terror Lake. Periodic field discharge measures were used to build stage–discharge rating curves for each gage location. Rating curves were then used in conjunction with continuous surface water elevation measurements to build hydrographs representing the real-time surface water discharge at each of the four gage locations. This report includes surface water data collected from April 23, 2013 to October 8, 2014. The surface water discharge data measured in Upper HBC at Gage D-East and Gage D- West was used to calculate the annual available water resources for the proposed Upper Hidden Basin Diversion Project. Gage D-East and Gage D-West are located at a mean elevation of 1,420 ft and have drainage areas of 1.26 square miles (mi2) and 3.42 mi2, respectively, comprising approximately 19% of the total HBC watershed. Following Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 2 2/11/2015 initial engineering analysis and field surveys, the location of the diversion dams was moved upstream of the gage locations causing an overall decrease in the total catchment area size from 4.7 mi2 to 3.8 mi2 or 15% of HBC watershed. The cumulative water yield available for the Upper Hidden Basin Diversion Project delivery to Terror Lake was approximately 29,503 acre feet (ac ft) for the full 2014 WY. Much of the data used to generate the water yields at the Upper Hidden Basin Diversion Project were collected at adjacent gaging stations and extrapolated to the respective diversion locations using the proportion of catchment area size. This approach was validated by comparing initial discharge data to historic United States Geological Survey (USGS) gage data. The magnitude, frequency, and duration of mean daily discharge were similar between the USGS data and the Gage D-West locations. Surface water discharge does not increase in a downstream direction between the headwater tributaries and the mainstem of HBC despite a substantial increase in catchment area including the ungaged inputs from the Middle and East Forks of HBC along with several unnamed tributaries. The proportion of surface water discharge contributed directly from the Upper Hidden Basin Diversion Project to the mainstem of HBC cannot be accurately quantified through surface water stream gaging alone due to the porous substrate in the mainstem of HBC causing a longitudinal decrease in surface flows compared to upstream locations. Several ungaged catchments contribute both surface water and groundwater to the mainstem HBC. The Middle and East Forks of HBC comprise substantial drainage areas along with several unnamed tributaries not accounted for in the surface water measurements alone. An alternative approach was used to compare the proportion of discharge contributed from each headwater area in HBC by calculating the discharge based on drainage area size for each catchment. Mean daily discharge for USGS Gage 15297100 and 15297110 was used to synthesize hydrographs for the ungaged catchments in HBC for longitudinal comparisons of surface water yields. Surface water discharge in the synthesized hydrograph is typically 2.5 times greater at Gage 2 compared to discharge measures for the Upper Hidden Basin Diversion Project. Likewise, the synthesized discharge at Gage 3 further downstream is an additional 2 times greater than Gage 2 throughout the year. The addition of the Middle Fork and East Fork in the discharge yield analysis indicates the Upper Hidden Basin Diversion Project comprises a much smaller percentage of the overall water yield for Gage 3. The surface water data collected in 2013 and 2014 did not include the Middle and East Forks in the overall hydrology balance sheet. Surface water measures at Gage 3 in 2013 and 2014 also failed to quantify the contributions from the Middle and East Forks because much of the contribution from these catchments, like the West Fork, go subsurface and are not measurable using surface water sensors alone. Along with surface water hydrology, a fish presence / absence study was conducted in 2014. Minnow traps were set at each stream gage location in May, July, August, and October to better understand the longitudinal distribution of fish in HBC. In addition, Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 3 2/17/2015 adult distribution was documented through helicopter flights and ground observation for adult spawners. Potential fish passage barriers were documented through aerial reconnaissance. Fish passage barriers in the drainage include two waterfalls and the mainstem regularly dewatered except during peak flow events following storms and spring run-off. Waterfall A is approximately 50 ft high located between Gage 2 and field discharge Site 1b. Waterfall B is a smaller and is located directly upstream of the confluence with Upper East Fork and Upper West Fork of HBC. The dewatered stream channel occurs in the mainstem between Gage 2 and Gage 3. In May 2014 a total of 5 fish were collected in minnow traps consisting of Dolly Varden and a sculpin species. All fish collected in May 2014 were downstream of Waterfall A. In July 2014, a total of 19 Dolly Varden were collected, two were trapped above Waterfall A at Site 1b. In August 2014, 17 juvenile coho salmon and 42 Dolly Varden were collected. Only one Dolly Varden was collected above Waterfall A at Site 1b. In October 2014, 39 juvenile coho salmon and 66 Dolly Varden were collected at Gages 2 and 3. No fish were collected upstream of Waterfall A in October. No fish were collected or observed at the Gage D-West or Gage D-East on any of the sampling events. Fish distribution in the West Fork of HBC is influenced by the waterfall located in the lower reach of the West Fork (Waterfall A) as well as the fragmented habitat in the mainstem due to subsurface flows. Fish habitat between Gage 2 and Gage 3 is limited spatially and temporally. The dry stream channel in this reach presents a migration barrier for adults and juveniles. During storm events or periods of high run-off, fish may access the mainstem of HBC between Gage 2 and Gage 3 opportunistically but are likely to be trapped in pools with limited resources (dissolved oxygen, food) making them more vulnerable to disease, competition, and predation. Anadromous and resident fish are predominantly found in the reach downstream of Gage 3 with continuous surface water connectivity all the way to the marine confluence at Hidden Basin Bay. Water diversions at the Upper Hidden Basin Diversion Project are not likely to impact available fish habitat in the reach below Gage 3. The Upper Hidden Basin Diversion Project comprises only 15 percent of the overall HBC watershed area. Surface water flows downstream of Gage 3 are continuous.

INTRODUCTION This report summarizes a two-year study of Hidden Basin Creek (HBC) focusing on the hydrology longitudinally from headwaters to the lower elevation mainstem as well as fish presence / absence longitudinally in the watershed relative to potential upstream migration barriers. Kodiak Electric Association, Inc. (KEA) initiated a preliminary hydrology study in 2013 to assess the potential water resource for a proposed hydropower diversion from the upper portion of the HBC watershed to Terror Lake. The diverted water would supplement Terror Lake’s water supply and be used to generate power from the existing Terror Lake Hydroelectric Project, (Federal Energy Regulatory Commission Project No. 2743). The hydrology study quantifies annual flows in the HBC system allowing KEA to evaluate the quantity of water, and generating capacity to assess the viability of the Upper Hidden Basin Diversion Project. The hydrology assessment includes the following components: 1) installation and servicing of continuous-recording stage (water surface elevation) monitoring devices at four gaging locations longitudinally in HBC; 2) measurement of stream discharge associated with these gages; 3) construction of a rating curve from which continuous stage measurements were used to construct a stream flow record; 4) annual hydrographs ; and 5) the development of cumulative water yields for calculating power generation potential. In 2013, three continuous recording stream gaging stations were established in HBC to measure discharge longitudinally. In 2014, the upper most stream gage was moved 1.5 miles (mi) downstream. A fourth gage was added in 2014 in upper HBC to document flows in a tributary. A fish presence / absence study was initiated in the 2014 study season using minnow traps deployed at each of the stream gage locations in combination with aerial and foot surveys to document adult spawning distribution. Potential barriers to upstream fish migration were documented through aerial reconnaissance and photographs. This report provides an analysis of the available hydrology resource available for hydropower development based on the field work completed in 2013 and 2014 and subsequent hydrology data analysis for those respective gage locations including rating curves, surface water discharge, and cumulative water yields. The hydrology analysis also incorporates available data from the United States Geological Survey (USGS) data record, which was found to correlate well with recently collected data, as well as surface water estimates based on watershed size. The report also includes a summary of the fish habitat conditions longitudinally in HBC based on the presence / absence study conducted in 2014. 1.1. Project Description KEA conducted the hydrology and fisheries resource assessment to evaluate the potential for constructing a diversion system on the upper reaches of the West Fork of Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 5 2/11/2015 HBC. The Upper Hidden Basin Diversion Project would supplement the available water supply for the Terror Lake Hydroelectric Project by capturing additional snow melt and rain in the upper reaches of the HBC watershed and convey it to the existing Terror Lake reservoir. Structural components for the proposed project would consist of two dam embankments connected by a channel or pipe, an intake structure connected to subterranean tunnel that would run through a mountain ridge, and a gravel road for construction and future maintenance access. The diversion components would be a simple, non-mechanical design intended for un-manned water conveyance. Combined total diversion capacity from the D-West diversion and D-East Diversion would be approximately 900 to 950 cfs. Surface water flow that exceeds the capacity of the Upper Hidden Basin Diversion Project conveyance and tunnel will be spilled downstream over the diversion dams into the West Fork of HBC. Once the water from the Upper Hidden Basin Diversion Project flows into the Terror Lake reservoir, the additional hydropower would be generated from the existing Terror Lake Hydroelectric Project and fed directly into the KEA grid. KEA provides electricity to approximately 5,800 meters on Kodiak Island in a service area that includes the region in and around the City of Kodiak, the U.S. Coast Guard Base, Bell’s Flats, Chiniak, Pasagshak, and Port Lions. The Terror Lake Hydroelectric Facility is the primary source of KEA’s energy supply. It is located approximately twenty mi southwest of Kodiak. Water is diverted from the Terror Lake reservoir to the generating facility through an approximately five-mile long power tunnel. The Terror Lake powerhouse contains three vertical axis impulse Pelton-type turbine generator units for a total generating capacity of 33.75 megawatts. Enhancing water availability to Terror Lake with a new diversion would allow KEA’s future electrical load growth to be continually powered with renewable energy. KEA is committed to pursuing renewable energy sources, and the project will help Kodiak’s goal to have 95% of their electrical needs supplied by renewable energy. KEA’s renewable energy vision drives the pursuit of the Upper Hidden Basin Diversion Project as the next step for KEA’s expansion of available renewable energy supply to meet Kodiak’s future energy needs. 1.2. Study Area The landscape of Northwest Kodiak Island is characteristic of glaciation as evidenced by long, narrow fjords, and u-shaped valleys. The HBC drainage in the Northern portion of Kodiak Island originates in a mountainous area East of Terror Lake. HBC is short and steep, originating at an elevation of 2,500 ft above mean sea level. The stream flows in a predominantly south and southwest direction for approximately six miles before discharging into Hidden Basin which is at the northwestern end of Ugak Bay. Due to its elevation, steepness and terrain shading, snow can remain in the headwaters area well into the month of June. Kodiak Island is known for its maritime climate which is mild by Alaska standards. Average rainfall is 67.6 inches (in) per year and average snowfall is 78.7 in per year (National Oceanic and Atmospheric Administration (NOAA) 2003). Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 6 2/11/2015 The Upper Hidden Basin Diversion Project is located in the headwaters of the West Fork of HBC referred to as Upper HBC. The Upper HBC catchment area includes the Upper West Fork and Upper East Fork of the West Fork HBC. Upper HBC is characterized by high gradient step-pool morphology, large boulder/bedrock substrate, and cataracts (rapids and waterfalls) interspersed with pools and undercut banks. The proposed Upper Hidden Basin Diversions are located in this steep headwater area at a mean elevation of 1,530 ft where the two forks (the Upper West Fork and Upper East Fork of the West Fork) are approximately 2,000 ft apart. Downstream of Waterfall B, below the proposed Upper Hidden Basin Diversion Project, the gradient flattens and the valley broadens in an upper meadow area. The creek bed in this meadow area braids through fluvial flood plains and surface flows are dominated by riffles over a smaller boulder/cobble substrate. Several tributaries converge in this meadow, each contributing to surface flows. A tributary entering from the southwest originates in glaciated mountains and contributes flow to the drainage year round. Downstream of the upper meadow, the gradient steepens through the lower canyon section of the West Fork of HBC and drops again over a 50 ft vertical waterfall where the surface waters are confined by steep bedrock cliff walls. The gradient substantially flattens again before exiting the canyon, transitioning from a boulder/bedrock step-pool to boulder/cobble riffle morphology. The Middle Fork and East Forks of HBC join together with the West Fork of HBC at the canyon mouth forming the mainstem of HBC. Several unnamed tributaries with steep gradients also provide surface water inputs along the 3.1 mile (mi) length of the mainstem. Two of these tributaries contain lakes in their headwaters which provide storage to help maintain base flows. The HBC mainstem has a relatively flat gradient characterized by a meandering channel with multiple channel braids. The substrate is dominated by alluvial materials consisting of small gravels interspersed with large cobbles and boulders transported during peak flow events. The outfall is an inter-tidal estuary where channel depth varies dramatically between high and low tide. HBC flows south six miles into Hidden Basin, a natural saltwater lagoon, before discharging into Ugak Bay (Figure 1-1). The total drainage area for HBC from the confluence with the marine environment is approximately 25.5 square miles (mi2). The Upper Hidden Basin Diversion Project would divert surface water from 3.8 mi2 of the Upper HBC drainage into Terror Lake. This comprises only 15% of the total watershed area in HBC (Figure 1-2).

METHODS This section describes the gage locations, gage installation, field discharge measurement methods, and the development of the discharge rating curves and discharge calculations using continuous measurement water level sensors. This section also describes the methods used to document fish presence / absence longitudinally in HBC. Data were obtained, managed, and analyzed using scientifically appropriate and widely accepted and repeatable sampling techniques. 2.1. Gage Site Selection Stream gaging stations were established in HBC to measure surface water discharge longitudinally. Stream gaging stations provide the foundation for the collection of continuous surface water elevation (stage) data that is later converted to a discharge volume using a rating curve that plots the relationship of surface water stage height to discharge. Three surface water gaging stations were established longitudinally in HBC in 2013 to quantify surface water flows from the headwaters to the lower reaches of the creek. The longitudinal placement of gaging stations was selected to evaluate the proportional contribution from catchment areas in a downstream progression. The field location of each gage was recorded using a global positioning system (GPS). A helicopter field reconnaissance was performed on April 22, 2013 to determine accessibility and gage site selection for proper gage installation. Gage 1 was installed on June 14, 2013 located at a pool tail-out on the West Fork of Upper HBC at approximately 2,000 feet of elevation. The Gage 1 site was selected to quantify water yields available for power generation in the Upper HBC in the vicinity of the proposed diversion. Gage 1 site selection was also influenced by potential avalanche conditions during the initial installation. Gage 1 was established June 14, 2013 once significant dangers presented by avalanche conditions subsided. During the initial April 2013 field work, when the Gage 1 location was not accessible due to snow pack, a temporary surface water discharge location (Field Discharge Measure 1b) in a location just upstream of the lower canyon section was established. Field Discharge Measure 1b was intended to serve as a surrogate discharge site until the Gage 1 location was installed. Discharge measures at Gage 1 in the 2013 water year indicated sufficient surface water yields for power generation warranting further investigation in 2014. In 2014, following a year of planning discussions and a better understanding of diversion dam locations, Gage D-West and Gage D-East were established. Gage D-East and Gage D-West were installed prior to the engineering team’s site visit and conceptual design. As a result, the gage locations are a short distance downstream of the proposed diversion dam locations for D-East Diversion and D-West Diversion. The gages are in relatively close proximity to the proposed diversion dam locations and are representative of the available surface water in the area. The Gage 1 site, established in Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 10 2/11/2015 2013, was no longer necessary with the establishment of Gage D-East and Gage D-West and was decommissioned in July of 2014. Gage D-West was installed on May 16, 2014. This gage station was established at 1,420 ft elevation on the West Fork of Upper HBC just downstream of the confluence of a south and east flowing unnamed tributary but downstream of the proposed diversion location. Initially, at the time of installation, Gage D-West was thought to be the proposed diversion location, but was since relocated upstream based upon further engineering study. Gage D-West therefore includes surface water from an additional tributary that would not be diverted as part of the Upper Hidden Basin Diversion Project. Gage D-East was installed on the February 6, 2014 in the East Fork of Upper HBC. Unseasonably warm weather and the lack of snow cover during the winter of 2014 in Upper HBC made it possible to conduct field work so early in the season. Upon investigation of the site at the proposed diversion (~1,500 ft elevation) field hydrologists determined that the steep stream gradient and difficult access necessitated moving the gage station downstream. As a result, the stilling well and gage was installed at approximately 1,200 ft elevation where access and stream gradient was more practicable for a stream gage. There are no tributaries or additional direct surface water contributions between the proposed diversion site and where the gage was ultimately located. As a result, the data gathered in this location accurately estimates the surface water available for diversion at the D-East Diversion site. Gage 2 was installed to quantify the amount of surface water delivered from the West Fork of HBC before the contributions of the Middle and East Forks join the HBC mainstem. This gage was installed on April 25, 2013. Gage 2 was placed immediately above the confluence of the West Fork of Upper HBC with two major tributaries (Middle and East Forks of HBC). The Gage 2 location coincides with USGS No. 15297110 (Hidden Basin C Nr Mouth near Kodiak AK). The period of record for the USGS gage operation was March 1, 1983 and January 31, 1984. Gage 3 was installed on April 25, 2013 to measure surface water discharge at the mid- point of the mainstem of HBC. Gage 3 was selected because it is the best “choke point” to measure discharge in the mainstem which for most of its length is a wide, meandering, braided, alluvial channel. For much of its length from the confluence with the West, Middle and East Forks to Gage 3, surface water is absent due to downwelling resulting in disconnected pools interspersed with sections of dry stream channel. Surface water connects these pools during peak spring run-off conditions and peak flows during large storm events. Stilling wells were established at each gage location housing pressure transducers. Gage sites were selected in locations containing a suitable location to anchor a stilling well (bedrock cliff walls or large boulders) and offering protection from high flow events. Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 11 2/11/2015 2.2. Stream Gage Station Design Stream gaging stations were established to continuously record surface water elevations which were then converted to discharge volumes. Each stream gage location contains a stilling well, a pressure transducer recording water height and an analog staff gage. The stilling well functions as housing for the pressure transducer (Solinst 3001 LT Levelogger Edge, M5/F15) data logger that records real-time fluctuations in water surface elevation (stage) when compensated for atmospheric pressure. Solinst 3001 LT Barologger Edge (M1.5/F5) sensors were deployed at the Gage 1 and Gage 3 locations in 2013 to allow compensation for real time atmospheric pressure fluctuations at each site. Two separate barologgers were installed to account for elevation differences longitudinally in HBC between gaging stations. In February 2014, a third barologger was installed at D-East coinciding with installation of the stream gaging equipment there. An analog staff gage was mounted to the outside of the stilling well for redundancy and to provide hydrologists with a check for adjusting pressure transducer stage height if necessary. The stilling well was constructed with 2-in galvanized steel pipe or schedule 40 PVC. The pipe or PVC was secured to existing stable features in the stream channel such as bedrock or large boulders using 3/8 in x 5 in concrete anchor bolts and 1/8 in x 1 in pre-drilled steel hanger strap or a Unistrut system. The stilling wells were located in areas of the channel that were protected from high velocities and debris. To the extent possible pressure transducers were installed such that they would capture data at all flow levels (Photograph 2-1). The analog staff gage consisted of a 3.33 ft gage plate attached to a suitable backing and anchored to or adjacent to the pressure transducer housing for analog recording during site visits and subsequent calibration of the pressure transducer. At Gage 3, a second analog staff gage (3.33 - 6.67 ft gage plate) was attached to a T-style fence post to record stage heights exceeding the 3.33 ft gage. In order to correlate discharge with water level height at each gage station on an ongoing basis, the elevations of the staff gage and pressure transducer were surveyed using a Transit level and referenced to two permanent benchmarks established at each of the gaging sites. Benchmarks were established using either an expandable rock anchor bolt drilled into the bed rock above the gage location or rebar driven into the river bank above the high water mark. The initial benchmark was arbitrarily set to 100.00 ft and the elevation of all other survey points were relative to this point. A Kevlar tape measure was used to establish horizontal stations across cross sections. Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 12 2/11/2015 PHOTO 2-1. GAGE D-WEST STILLING WELL AND TYPICAL GAGE INSTALLATIONS 2.3. Discharge Measurement Discharge was measured during each site visit to develop a correlation between surface water elevation and water volume. Discharge was measured at a representative cross section, which was defined using a tagline stretched across the active channel perpendicular to flow. Cross sections were established in a relatively straight portion of the channel in an area where flow was distributed as uniformly as possible across the channel. Standard guidelines for cross section selection and placement were followed. Meander bends were avoided, as were obstructions such as boulders and areas of the channel that narrowed or widened appreciably. Discharge at each gage site was measured using the USGS midsection method. The method is based on protocols developed by the USGS (Buchanan et al. 1969; Rantz et al. 1982; and Nolan et al. 2007). The midsection method divides the stream into a number of rectangular partial sections across the channel and assumes that the velocity measured in each partial section represents the mean velocity of that section. The width and depth of each partial section is multiplied by the average velocity in that section such that a discharge for each partial section is calculated. The summation of the calculated discharges for all the individual partial sections is the total discharge for the stream (Figure 2-1). Velocity in each partial section was measured using a Marsh-McBirney velocity meter mounted on a top setting wading rod. The width of the active channel was measured using a Kevlar tape to define the total cross section width as well as individual partial Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 13 2/11/2015 sections. The spacing of the partial sections along the tape was calculated based on the width of the active channel, and the number of partial sections needed. The USGS midsection method stipulates that the ideal measurement will have less than five percent flow in any single partial section, thus the cross section was typically divided into 25 to 30 partial sections. Flow depth and velocity was measured at stations along the tape that represent the midpoints of the partial sections using the wading rod and velocity meter. At each partial section, if water depth was less than or equal to 2.5 ft, mean velocity of the section was determined using a single velocity measurement at 0.6- depth below the water surface. If the water depth was greater than 2.5 ft, velocity was measured at 0.2 and 0.8 of the observed depth below the surface then averaged to calculate the mean velocity of the subsection. Discharge notes for each of the partial sections were recorded in the field notebook. Total discharge and other pertinent parameters were then calculated in an electronic spreadsheet using the field measurements. FIGURE 2-1: USGS MID-SECTION METHOD 2.4. Stage-Discharge Rating Curve Development A rating curve was developed for each gage location to correlate surface water elevations recorded continuously by the pressure transducer to a discharge volume. The field discharge measurements collected at each gage station in 2013 and 2014 provided an instantaneous flow rate and a corresponding staff gage height. Field discharge, pressure transducer measurements, and staff gage readings were plotted graphically. A mathematical regression was applied to create a discharge rating of the stage–discharge relationship. The resulting rating curve formula was specific to each gage location accounting for the unique channel shape and controls at each site. A regression formula was calculated for each gage site location. Either a power function or a 2nd order polynomial was used to establish the rating curve at each of the four gage sites. The use of either a power function or a 2nd order polynomial was determined by evaluating which function best fit the data. The function with a correlation coefficient, the R- Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 14 2/11/2015 squared value, closest to 1.0 represents the best fit. Rating curves and correlation coefficients for respective gage locations are provided in Appendix A. The discharge rating curve function was used to calculate discharge based on stage data continuously recorded by the pressure transducers housed in the stilling wells. The stage data downloaded from the pressure transducer was corrected using the barometric pressure data from the nearest barologger and then multiplied by the rating curve function to produce a discharge measurement calculation for each data point. 2.5. Catchment Area Size In order to quantify the proportion of water diverted at the Upper Hidden Basin Diversion Project relative to downstream locations, particularly the mainstem downstream of Gage 3, catchment area sizes were calculated using geographic information system (GIS) tools. The USGS National Hydrography Dataset Watershed Boundary Dataset, HUC 12 level was used for the HBC watershed. Sub-catchment drainage areas within HBC watershed were digitized from USGS 63K (1 inch = 1 mile) topographic map contours provided by the Geographic Information Network of Alaska (GINA) webmap service. 2.6. Synthesized Hydrographs for Ungaged HBC Catchments The loss of surface water to subsurface flows at Gage 3 eliminated the ability for straightforward analysis of the proportion of surface water flow measured at Gage 3 originating in Upper HBC. Furthermore, the loss of surface to subsurface flows at Gage 3 eliminated the ability to quantify the contributions from the Middle Fork and East Forks of HBC as well as unnamed tributaries relative to the West Fork of HBC. In order to quantify the contributions of each catchment area to the overall water yield, surface and subsurface flows, in the mainstem of HBC, hydrographs were synthesized using average daily discharge data from USGS gages located in HBC. Hydrographs for ungaged catchments in HBC were synthesized using the drainage-area ratio method (Hirsch 1979) extrapolated from the average daily discharge data at the USGS gages. The drainage-area method assumes that within a given area, discharge is directly proportional to drainage area. The accuracy of this method requires that gages be within a similar or the same hydrologic area, and increases with the redundancy of gages over a given period. For longitudinal comparison purposes using similar water year characteristics, hydrographs were synthesized for Gage D-East, Gage D-West, Gage 2 Gage 3, the Middle Fork of HBC and the East Fork of HBC as well as unnamed tributaries entering the mainstem. Two USGS gages located in the West Fork of HBC contained discharge data over the same period of time in the 1980’s from which to construct synthesized hydrographs. These gages were the USGS No. 15297100 (Hidden Basin C near Port Lions AK) and USGS No. 15297110 (Hidden Basin C Nr Mouth near Kodiak AK). The period of record for both gages was between March 1, 1983 and January 31, 1984. This comprises nearly Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 15 2/11/2015 an entire year’s worth of data, excluding February. The period of record for USGS No. 1527100 was longer (between August 1, 1982 and January 31, 1984). Drainage areas for the entire HBC (to its mouth at Hidden Bay) and all sub-catchments of interest were delineated from topographic layer data (GINA), best data layer web mapping service Extras, and hill shaded digital raster graphic using GIS. Two sets of average daily discharge values were calculated for the entire HBC drainage by applying the drainage-area ratio method to the two USGS gage data sets independently. These values were then averaged to calculate an average daily discharge value based on the combined USGS data sets. Further application of the discharge-area ratio method produced average daily discharge values for each sub-catchment of interest as respective percentages of the larger HBC basin quantities. 2.7. Fish Presence / Absence in HBC In 2014, KEA initiated a fish presence / absence study at the established gage locations as well as Site 1b directly upstream of a large waterfall in the West Fork of HBC. Prior to this study, little was known about fish distribution in the drainage and habitat available for various life stages of fish. This initial effort to document fish presence / absence at respective gage locations combined with aerial flights to document spawning adults coupled with ground documentation provided insights on fish distribution relative to the mainstem and West Fork of HBC. Minnow traps were set at each gage locations in HBC. The objective of the fish trapping program was to document the presence or absence of fish longitudinally. Wire-mesh minnow traps have demonstrated effectiveness sampling juvenile salmon in difficult to access habitat such as deep pools or dense cover (Swales 1987). Adult fish distribution was documented using aerial flights and observations by foot. The lower 3 miles of HBC, the mainstem of HBC below Gage 2, is designated an anadromous waterway in the Catalog of Waters Important for the Spawning, Rearing or Migration of Anadromous Fishes (Johnson and Coleman 2014) otherwise known as the State of Alaska Anadromous Waters Catalogue (AWC). This reach is listed as supporting chum and pink salmon, as well as Dolly Varden. Passive capture techniques such as minnow trapping are appropriate methods for detecting the presence or absence of fish (Royle and Nichols 2003) when used during a time of year when fish species and specific life stages are most likely to be present in the area sampled. Minnow trapping can provide reasonable indices of change in stock abundance over time when they are fished in a similar manner, location, and time of year (Hubert 1996). Minnow traps were used for the capture and collection of fish at respective gage locations under Alaska Department of Fish and Game (ADFG) Fish Resource Permit #SF2014-153 received on April 3, 2014. Traps were placed in areas considered to be good juvenile salmonid habitat: areas with a relatively low velocity and ample cover if Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 16 2/11/2015 available. In complex habitats (e.g. frequent cover opportunities, many side channels, etc.) traps were set more closely, while more homogeneous habitats required greater spacing between traps. Galvanized minnow traps with 0.32 centimeter (cm) size mesh and two 1.90 cm funnel openings were baited with salmon roe. Overall trap dimension was 44 cm length by 23 cm width. All traps were set such that at least one entry funnel was fully submerged. Approximately two ounces of betadine-cured salmon roe was placed in a nylon stocking and suspended from the middle of each trap. The traps were set for approximately 24 hours. A total of 15 traps were deployed during each trapping event in May, July, August, and October. Three minnow traps were placed at each of the four stream gage locations. A fifth minnow trapping site was located upstream of a large waterfall (Waterfall A) thought to act as an upstream fish migration barrier. This site corresponds to the location of field discharge measurements at Site 1b in Upper HBC in the shallower gradient meadow area. Photograph 2-2 illustrates a typical minnow trap set at the margin of the creek, under overhanging cover, and in an area of low stream velocity. The three minnow traps per gage were placed directly upstream or downstream of the respective stream gage location in suitable stream habitat for juvenile fish. Traps were labeled according to gage location and location relative to one another. Gage and locations were abbreviated as follows: G3 = Gage 3; G2 = Gage 2; 1b = Site 1b; DE = Gage D-East; DW = Gage D-West. The stream gage number was followed by a number from one to three with the furthest downstream trap receiving the lowest number. For example, Trap DW-2 was set at Gage D-West and located between DW-1 and DW-3 in the stream channel. After traps were set they were photographed and their GPS locations were recorded. All living organisms collected in the traps were transferred to a five-gallon bucket filled with freshwater. Fish were placed in a separate three-gallon bucket containing a 25 mg/L clove oil solution to anesthetize them for accurate measurements and identification. Fish were identified to species (except for sculpin), measured to the nearest millimeter (mm) total length, weighed to the nearest 0.1 gram (g), and photographed. After identification and measurement were completed, the fish were placed in a five-gallon bucket of freshwater until they resumed active behavior, then were returned to the stream location from which they were collected. All data was recorded in “Rite in the Rain” notebooks. Throughout the course of this study no fish specimens were retained for identification and no fish mortality occurred.

RESULTS This section describes the field work completed in 2013 and 2014 including field discharge measurements and fish presence / absence and data analysis necessary for developing site specific hydrographs including rating curves for Gage D-West, Gage D- East, and Gages 2 and 3 as well as calculating water yield for the Upper Hidden Basin Diversion Project. 3.1. Stage-Discharge Relationship Table 3-1 presents a summary of installation dates and field discharge measurements for each gage station in the HBC watershed in 2013 and 2014. The data described in this section was used to develop the stage-discharge rating curve applicable for each stream gage. The rating curves (Appendix A) were then used to build the hydrographs for each location based on water levels continuously recorded by pressure transducers at each stream gage location. Each gage locations as well as the watershed characteristics are documented in photographs contained in Appendix B. Gage 1 3.1.1. Surface water discharge at Gage 1 was measured four times in 2013 and once in 2014 prior to decommissioning. Measured discharge ranged from a low of 12.6 cfs in July 2014 to a high of 54.8 cfs in June 2013. Indicative of the flashy nature of the drainages on Kodiak Island, discharge measured on October 3, 2013 (50.4 cfs) was over three times the discharge measured the following day (15.4 cfs). Discharge measured on October 3, 2013 was associated with 1.84 in of rain recorded at the National Weather Service Station in Kodiak (PADQ). Gage D-West 3.1.2. Surface water discharge at Gage D-West was measured during four site visits in 2014; May, July, August and October. In total, 9 field discharge measurements were made ranging from a low of 3.4 cfs in October to a high of 90.7 cfs in May. All flow measurements were taken from the same cross section of the stream channel to ensure correlation between visits. Gage D-West is located in a stream reach dominated by large boulder substrate and stable bank configuration. Gage D-East 3.1.3. Surface water discharge was measured at Gage D-East during five site visits in 2014; February, May, July, August and October. In total, 10 field discharge measurements were made at D-East resulting in surface water discharges ranging from a low of 1.3 cfs measured in October to a high of 37.2 cfs measured in May. All flow measurements were taken from the same stream channel cross section to ensure correlation between visits. Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 19 2/11/2015 Gage 2 3.1.4. Surface water discharge was measured three times in 2013 at Gage 2, ranging from a low of 16.6 cfs on April 23, 2013 to a high of 78.4 cfs on July 24, 2013. In 2014, discharge was measured nine times ranging from a low of 9.1 cfs measured on October 7, 2014 to a high of 104.3 cfs measured on July 14, 2014. High flows on May 17, 2014 prevented safe measurement of discharge at this location. High flow events in 2013 destroyed Gage 2 in mid-August of that year. Substantial bedload movement leading to changes in channel geometry occurred between the August 2013 and October 2013 site visits at Gage 2. Gage 2 was re-installed May 17, 2014. Surveys of the channel cross section illustrate the change in channel shape from April 2013 to July 2014 (Figure 3-1). In 2014, the channel was one ft deeper compared to April 2013. Because of the high flow event destroying Gage 2, continuous discharge data was not recorded for this location from July 24, 2013 to May 17, 2014. In order to perform longitudinal comparisons between gage locations, discharge data from the USGS gage No. 15297110 adjacent to the Gage 2 location was used in the hydrology analysis using synthesized hydrographs. FIGURE 3-1: GAGE 2 CHANNEL CROSS SECTION COMPARISONS, 2013 AND 2014. Gage 3 3.1.5. In 2013, Gage 3 discharge was measured four times ranging from a low of 1.1 cfs on April 25, 2013 to a high of 478.2 on June 15, 2013. In 2014, Gage 3 discharge was measured six times ranging from a low of 13.1 cfs on August 28 to 447.9 cfs on May 18, 2014. The only flows present at Gage 3 during the October 2014 site visit were from a 91 92 93 94 95 96 97 98 99 100 101 0 20406080100120Relative Elevation (ft)Station (ft)Apr-13 Jul-14 Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 20 2/11/2015 small tributary drainage entering the main channel on the river right bank approximately 250 ft upstream of the gaging location and were estimated at 0.1 cfs. The mainstem of HBC upstream of Gage 3 was dry during this October 2014 site visit. During the October 2013 site visit, it became apparent that the channel geometry had changed substantially at Gage 3, likely the result of the same high flow events in August 2013 that destroyed Gage 2. Figure 3-2 documents the channel bed changes between April 2013 and August 2014. As a result of the change in channel geometry, the rating curve at Gage 3 used for calculating surface water discharge from the pressure transducer stage recordings was valid through August 05, 2013 only. A new rating curve was developed in 2014 after additional surveys of the channel geometry along with discharge and corresponding stage height measurements in 2014. Gage 3 was winterized in October 2013. The pressure transducer data recorded between October 2013 and May 2014 was not considered accurate due to changes in the channel geometry altering the stage - discharge relationship. As a result, the data for that time period was not used in this report. There were several significant weather systems over the period of months between October 2013 and May 2014. One particular system dropped 6.64 in of rain over the course of five days in January. Events like these, besides having an impact on channel geometry and surface water controls, mobilize fine material in the stream that settles inside the stilling well and around the pressure transducer. As a result, stage readings can be falsely elevated and return unrealistic discharge volumes when calculated with the discharge rating curve. These false readings were removed during data review process. The mainstem of HBC contains a dynamic stream channel that changes shape and location during large precipitation events that mobilize the alluvial bedload. The downwelling of surface water to subsurface flows in this reach further increases the difficulty of measuring the total contributions from upper HBC. The regularly shifting channel shape in the mainstem reach makes maintaining a relevant stage–discharge relationship throughout the year challenging.

Catchment Area Size Comparisons Drainage area size was calculated for each gage location as well as ungaged catchments (Table 3-2). For comparison purposes, the catchment area size was also expressed as a percentage relative to the size of the entire HBC drainage. Gage 1 was located at 2,000 ft in the mainstem of West Fork of Upper HBC and has a catchment area of 1.29 mi2 or 5.2% of the total catchment of HBC (Figure 3-3). Gage D-East is located at 1,200 ft elevation in the upper reaches of the valley on a tributary to the West Fork of Upper HBC and has a catchment area of 1.26 mi2 or 5.1% of the total catchment of HBC. Gage D-West is located at 1,420 ft elevation at the initially chosen site for the proposed diversion dam location on the main reach of the West Fork of Upper HBC and has a catchment area of 3.42 mi2 or 13.8% of the total catchment of HBC. The drainage area of Gage D-West and Gage D-East combined is 4.69 mi2 comprising 18.9% of the total area of HBC. The D-East and D-West Diversions are located upstream of the respective stream gages at D-East and D-West. The respective diversion locations were located upstream after the initial engineering analysis and survey determined it was necessary to relocate upstream to higher elevations to provide the proper grade for delivering water to Terror Lake. As a result, the total catchment area of the proposed diversion project is 3.82 mi2 or 15.4% of the total area of HBC. Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 24 2/11/2015 Gage 2 is located at 200 ft elevation at the mouth of the lower canyon upstream from the confluence with the Middle and East Forks of HBC. Gage 2 catchment area is 11.76 mi2 or 43.7% of the total catchment of HBC. Gage 2 captures three times more area than the proposed diversion project. Gage 3 is located at approximately 100 ft elevation 1.5 mi from the mouth of the creek where it discharges into Hidden Basin. The catchment area at Gage 3 location is 21.70 mi2 or 87.3% of HBC. Gage 3 captures 5.7 times more area than the proposed diversion project. Upstream of Gage 3 and downstream of Gage 2 two additional major tributaries (Middle Fork and East Fork) converge with the West Fork of HBC. The Middle Fork has a drainage area of 4.63 mi2. The East Fork has a drainage area of 2.17 mi2. Together these tributaries comprise 27.3% of the total drainage area of HBC. TABLE 3-2: DRAINAGE AREA (MI2) FOR EACH GAGE LOCATION.

Hidden Basin Creek Hydrology The hydrology in HBC is characterized by a spring snowmelt hydrograph overlaid by flashy, short duration high flow events associated with heavy precipitation events throughout the year. This is evident on the hydrographs as steep spikes with very little ascending or descending lag time prior to or after the peak flow. Persistent rain throughout the year saturates the soil and underdeveloped flood plains through much of the basin resulting in an abrupt increase in the surface water discharge shortly following precipitation events. During the early spring months it is not uncommon to receive heavy rain on a deep snow pack, accelerating the rate of snow melt with latent heat of precipitation. Monthly mean, maximum, and minimum flow statistics for gaged sites are presented in Table 3-3. This table illustrates the differences between the discharge observed in the upper reaches relative to the mainstem of HBC. Maximum flows recorded per month provide a foundation for size of the water conveyance pipe. Representative hydrographs for HBC are included in this section. Hydrographs were plotted for respective years of data collection and displayed on a generic water year axis (October 1 through September 30) for comparison between years. 2013 and 2014 Discharge 3.3.1. Surface water discharge in HBC was reported for the D-West Diversion, Gage D-West and Gage D-East (Figure 3-4) by water year. Gage 1 discharge measured from June 14, 2013 – May 15, 2014 was extrapolated based on catchment area size ratios to the D-West Diversion to illustrate the quantity of water available for power generation. Gage D- West was installed on May 16, 2014. Discharge data collected at Gage D-West from May 16, 2014 to October 8, 2014 was extrapolated to the catchment area of D-West Diversion Gage D-East data was determined to be representative of surface water conditions at the D-East Diversion since no tributaries enter this reach between the proposed diversion and Gage D-East. Peak discharge events coincide with large precipitation events that elevate the stage of the water in the creek. During much of the year, maximum monthly peak flow in HBC for respective locations exceeds the minimum monthly flow by two to three orders of magnitude (Table 3-3). These peak flow events contribute substantially to the mean monthly water yield. Local precipitation data for 2014 was obtained from the National Weather Service (NWS). At the D-West Diversion location, the peak flow in 2013 was recorded on August 6th at 862.9 cfs. This peak flow at D-West Diversion was based on discharge data recorded at Gage 1 extrapolated to the D-West Diversion location. The peak flow coincided with 1.72 in of rain recorded at PADQ. In 2014, the D-West Diversion peak flow was 1,285.7 cfs recorded on January 17, 2014. Again, this peak flow was based on Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 27 2/11/2015 TABLE 3-3: HIDDEN BASIN CREEK HYDROLOGY STATISTICS Mean Max Min Mean Max Min Mean Max Min Mean Max Min Mean Max MinMarch---------------April---------17.040.50.20.81.20.4May---------63.1222.16.749.4549.80.7June ------126.5214.377.5174.3277.9112.0537.61545.3175.8July------93.4248.321.3123.7277.271.3188.7933.511.4August------39.3862.90.6---320.22156.221.8September------25.6 491.9 0.2 - - ----October------26.1723.50.6------November------6.7219.40.4------December------17.5397.50.3------January------57.71285.70.8------February6.9 105.5 0.9 - - - 7.0 78.0 1.5------March0.51.60.1---11.6570.6------April0.30.80.1---6.610.03.8------May17.0 73.3 0.4 94.6 249.9 45.3 76.6 202.4 36.7 124.9 251.5 77.2 208.8 1298.2 41.0June 30.7 191.6 12.6 84.8 342.0 41.3 68.7 277.0 33.5 118.7 349.5 69.5 264.7 4205.7 34.8July16.4 45.9 2.3 39.0 134.7 8.5 31.6 109.1 6.9 81.7 163.2 35.6 89.9 503.7 3.1August10.6 66.8 2.9 30.4 238.9 7.4 24.6 193.5 6.0 72.7 250.5 24.1 65.7 955.6 2.9September9.0 116.1 1.3 32.3 458.3 5.0 26.2 371.2 4.1 66.1 1149.6 9.4 211.9 13347.1 2.12015October1.5 2.3 1.0 5.1 9.2 4.2 4.1 7.5 3.4 8.1 13.8 4.1 2.3 4.8 1.2NOTES: D-East data includes Feb 6 - Oct 8, 2014; D-West data includes May 16 - Oct 8, 2014; Gage 1 data collection starts on June 14, 2013Extrapolated data: Gage 1 data was used from June 14, 2013 - May 16, 2014.

This January peak flow event coincided with a heavy precipitation event and warmer air mass. The NWS PADQ Station for January 2014 recorded 6°F warmer than normal temperatures for the month compared to the statistical records and received over six in more rain than average. On January 16th and 17th the PADQ station recorded 4.58 in of precipitation. Gage D-West began recording discharge on May 16, 2014. Discharge data for this analysis runs through October 7, 2014. The peak flow at Gage D-West from May 16, 2014 through October 07, 2014 was 458.3 cfs recorded on September 14 coinciding with 1.99 in of precipitation at PADQ. Gage D-East was installed on February 6, 2014. Discharge data for this analysis runs from the date of installation through October 7, 2014. The peak flow at Gage D-East was 191.6 cfs on June 6, 2014 coinciding with 2.98 in of precipitation at PADQ. The D-East and D-West gages did not peak on the same date in 2014. The D-East Gage is located in a steeper and tighter drainage with more northerly aspects compared to D- West Gage. This may have delayed snow melt in May. The rain on June 6th likely combined with snowmelt resulting in the peak discharge for the D-East Gage for 2014. There was a corresponding peak on the D-West Gage hydrograph on June 6, 2014 but it was not the peak discharge for that location in 2014. Surface water discharge for the West Fork and the mainstem of HBC was reported using data collected at Gage 2 and Gage 3 (Figure 3-5) by water year. The data collected at these locations is incomplete due to peak flow events damaging equipment and altering the channel shape. Gage 2 was forcibly removed from the bedrock wall it was attached to by high flows and bedload movement sometime between the July and October 2013 site visits. The gage station was re-established at an adjacent location May 17, 2014. At Gage 3, changes in the channel shape due to bedload movement during a peak flow event in August 2013 altered the stage-discharge relationship requiring a new rating curve to calculate discharge. Similar flow events over the winter of 2013/2014 between site visits to Gage 3 continued to alter the stage – discharge rating curve. The rating curve was re-established during the May 2014 site visit. Despite the limited data set, the hydrograph for Gages 2 and 3 illustrates the large discharge fluctuations in 2013 and 2014 in the lower reaches of HBC. The hydrograph also illustrates that during base flow conditions in HBC, surface water discharge at Gage 2 often exceeds discharge at Gage 3 confirming the downwelling of water to the subsurface that occurs between these gages in the mainstem. Peak flows at Gage 2 for the period of data collection occurred on September 14, 2014 when NWS recorded 1.99 in of precipitation at PADQ. The peak flow at Gage 2 on September 14, 2014 was 1,150 cfs. The peak discharge measured at Gage 3 between May 18, 2014 and October 7, 2014 was 13,347 cfs in September 2014 coinciding with the precipitation event of 1.99 in. Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 29 2/11/2015 Gage 3 surface water volumes did not increase in a linear pattern relative to longitudinal flow comparisons between upstream gages; Gage D-East, Gage D-West and Gage 2. This is likely due to the fact that surface water flows in the mainstem reach of HBC go below to the subsurface causing the stream channel to dry up between Gage 2 and Gage 3. The subsurface flows partially resurface at a point just upstream of Gage 3, but substantial portions of the mainstem of HBC upstream of Gage 3 remain disconnected with fragmented pools of surface water. In fact, during base flow conditions observed in April 2013, the mainstem of HBC was dry for substantial lengths upstream of Gage 3 despite a discharge of 41.5 cfs measured at Gage 2 on the same day. Similarly, in July 2013 during moderate flow conditions at Gage 2, the mainstem channel between Gage 2 and Gage 3 was dry in places indicating subsurface flow. During base flow conditions observed in October 2013, the mainstem of HBC was dry, with the exception of isolated standing pools upstream and downstream of Gage 3 despite a discharge of 9.1 cfs measured at Gage 2 on the same day. Similarly, on July 14, 2014 during moderate flow conditions at Gage 2 (discharge of 104.3 cfs), the primary channel between Gage 2 and Gage 3 was dry in places indicating subsurface flow. Discharge measured at Gage 3 on the same day was 86 cfs. Due to the subsurface flows in the mainstem channel coupled with contributions from ungaged tributaries downstream of Gage 2, the discharge proportion contributed directly from the Upper Hidden Basin Diversion Project to the Gage 3 location in the anadromous reach cannot be calculated based on surface water discharge measures alone. Accurate quantification of the proportion of surface water derived from the combined the Upper Hidden Basin Diversion Project relative to Gage 3 would require additional surface water gages located on the Middle and East Forks of HBC as well as unnamed tributaries combined with an exhaustive network of groundwater wells and geologic analysis of alluvial deposition to obtain a cumulative volume (surface and subsurface) at Gage 3. Even with this level of effort there would still be a high degree of uncertainty in the total volume of water (surface and sub-surface). Alternatively, analyzing water yields for respective catchments based on drainage area size regardless of flow pathways in the mainstem quantifies the proportion of the water withdrawal from the Upper Hidden Basin Diversion Project relative to specific locations downstream in HBC. The water yield analysis can be combined with knowledge of fish distribution and fish habitat in the mainstem of HBC to assess potential project impacts downstream.

The discharge data collected in Upper HBC in 2013 and 2014 was compared to historical data collected by the USGS in HBC as part of the data validation process and to include all available hydrology data for this report. The USGS installed and maintained two surface water gaging stations on the West Fork of Upper HBC between 1982 and 1984. The upstream station referred to as USGS 15297100 was located just downstream of the proposed D-West Diversion and approximately 300 linear ft upstream of Gage D-West. The downstream station referred to as USGS 15297110 was located at the mouth of the lower canyon on the West Fork of HBC approximately 200 feet downstream of Gage 2 (2013) location and 20 ft downstream of the current location of Gage 2. The 1983 data set represents the only full year of data collection for Gage 2. The USGS 15297100 data collected from 1982–1984 was compared to the discharge data collected at Gage 1 and Gage D-West (Figure 3-6). Surface water discharge collected at Gage 1 and Gage D-West was extrapolated downstream and upstream, respectively, to the USGS 15297100 location using the drainage area proportion of the watershed and normalizing data sets to a generic water year (October 1 through September 30). The magnitude, frequency, and duration of extrapolated surface water discharge data from Gage 1 and Gage D-West respectively are comparable to discharge measures recorded at USGS 15297100. The peak flows and elevated winter discharge observed for the Gage 1 (WY 2014) data is likely due to the 6°F above average winter air temperatures coupled with heavy precipitation events. The lower discharge during the mid-summer period in 2014 is likely due to the lack of mountain snowpack during the 2014 water year (personal observation and conversations). Synthesized Hydrographs for Ungaged Catchments 3.3.3. Mean daily discharge for USGS Gage 15297100 and 15297110 was used to synthesize hydrographs for ungaged catchments in HBC, as well as to compare gaged locations with discontinuous discharge data sets. Figure 3-7 illustrates a longitudinal hydrograph for the combined D-East and D-West Diversion, Gage 2, Gage 3, and the mouth of HBC at Hidden Basin. The hydrograph demonstrates the proportional increase in daily mean discharge as catchment area increases in a longitudinal fashion downstream assuming no water is lost to subsurface flow. Surface water discharge in the synthesized hydrograph is typically 2.5 times greater at Gage 2 compared to Gage D-East and the D- West Diversion (Table 3-4). Likewise, the synthesized surface water discharge at Gage 3 is nearly 2 times greater than Gage 2 throughout the year. Annual maximum flows for respective gage locations are lower in the data synthesized from the USGS data compared to surface water discharge measured in 2013 through 2014 due, in part, to the fact that the USGS data was daily mean flows as opposed to continuous recording discharge. This could also be a reflection of inter annual variation in precipitation between water years.

Data collected for the D-West Diversion covers the period from June 14, 2013 through October 8, 2014. For Gage D-East, data was extrapolated from the Gage 1 data collected from June 14, 2013 - February 6, 2014. After February 6, 2014, discharge data measured directly at Gage D-East was used for the calculations through October 8, 2014. A full year of discharge was measured in WY 2014. The total amount of water available for diversion into Terror Lake in WY 2014 was 29,585 ac ft (Table 3-5). The total amount of water available for diversion to Terror Lake during the partial year of measurement in WY 2013 was 19,954 ac ft. Generally, the contribution from the larger catchment area at D-West Diversion exceeds the contribution from D-East Diversion by a factor ranging between two and three depending on the month. For WY 2014, D-East Diversion comprises 28% of the total water available for diversion to Terror Lake. D-West Diversion provides the remaining 72% in WY 2014.

Fish Presence / Absence in HBC This section summarizes the results of the fish presence / absence observations made during site visits. Juvenile fish presence / absence was documented using triplicate minnow traps at four gage locations plus an intermediate field discharge location above a perceived fish migration barrier in 2014. Adult fish distribution was documented using helicopter flights combined with documentation on the ground. Anadromous spawners were observed in the mainstem of HBC as far as Gage 3, but were not found upstream of that point due to the dry stream bed between Gage 3 and Gage 2. Juvenile anadromous fish were collected as far upstream as Gage 2 in the West Fork of HBC.

WY 2014 Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 38 2/11/2015 Varden (Salvelinus malma) were collected in the West Fork of HBC upstream of an approximate 50 ft waterfall (Waterfall A) in a low gradient reach. No fish were collected or observed upstream of a second waterfall (Waterfall B) at Gage D-West or Gage D-East adjacent to the proposed diversion locations. The mainstem of HBC below Gage 2 is designated an anadromous waterway in the AWC. HBC is listed as supporting chum salmon (Oncorhynchus keta) as present in the drainage and spawns in the drainage, pink salmon (Oncorhynchus gorbuscha) as present in the drainage and spawns in the drainage, and Dolly Varden as present in the drainage. The AWC terminates the upstream boundary for anadromous fish distribution at the upstream end of the mainstem, the confluence with the West Fork, Middle Fork, and East Forks of HBC. In 2014, minnow trapping efforts associated with this study confirmed juvenile and adult coho salmon (Oncorhynchus kisutch) were present in the mainstem of HBC. Coho were not previously listed in the AWC for the mainstem of HBC. The results from these fish collection efforts have been presented to ADFG so the AWC can be updated to include coho. The fish presence / absence minnow trapping sites were selected to document fish distribution longitudinally in HBC relative to stream gradients and potential fish barriers (Figure 3-8). Upper HBC is a high gradient stream confined by narrow valley walls and dropping approximately 2,500 ft before reaching the mainstem of HBC. Upper HBC contains multiple cascades and two noteworthy waterfalls that present potential barriers to upstream fish passage, Waterfall A and Waterfall B. Photos documenting both waterfalls are labeled in Appendix B. Waterfall A is located approximately 0.5 mi upstream from the confluence of the West Fork of HBC with the mainstem of HBC and is approximately 50 ft in height. Waterfall B is located at the confluence of the Upper East Fork and Upper West Fork of Upper HBC. As noted, resident Dolly Varden were collected upstream of the first waterfall, Waterfall A, but were not collected above the second waterfall, Waterfall B, despite four sampling trips spread over the spring, summer and fall of 2014. The Dolly Varden above Waterfall A were only collected on two of the four sampling efforts in low numbers; 3 Dolly Varden total. The results of each minnow trapping field effort are described below for each site. Appendix C includes the minnow trapping data and Appendix D contains selected photographs of fish species collected. In May 2014, minnow traps were set on the 18th and retrieved on the 19th. Soak times ranged from a maximum duration of 22 hours 57 minutes at trap 1b-3 to the shortest duration of 15 hours 15 minutes at trap DW-3. A total of five fish were collected in four different traps: four Dolly Varden and one sculpin (Cottus sp.) (Photo D-1). All of the fish collected were trapped adjacent to Gages 2 and 3. Minnow traps were set in May at the three sample sites upstream of Gage 2 (Site 1b, Gage D-West and Gage D-East), but no fish were collected or observed at these three sample sites (Appendix C.1). In July 2014, minnow traps were set on the 15th and retrieved on the 16th. Soak times ranged from 18 hours 40 minutes at DW-1 to 22 hours 49 minutes at G3-1 (Table C.2). A Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 39 2/11/2015 total of 19 fish, all Dolly Varden, were collected in six different traps. Three of the Dolly Varden were trapped at Gage 3, 14 were trapped at Gage 2 and two of the Dolly Varden were caught at Site 1b located upstream of Waterfall A. No fish were collected at the D- West or D-East Sites in July. Surface water flow between Gage 2 and Gage 3 was continuous on July 14, 2014 although very shallow in places. On July 15th, the channel between Gage 2 and Gage 3 had gone dry in places resulting in isolated pools and runs with dry stream channel between. In August 2014, minnow traps were set on the 29th and retrieved on the 30th. Soak times ranged from a maximum duration of 23 hours 37 minutes at 1b-3 to 21 hours 49 minutes at G3-3 (Table C.3). A total of 59 fish were collected from seven different traps including 17 coho salmon and 42 Dolly Varden (Photo D-4). The majority of the fish caught in minnow traps, 58, were collected in traps at Gage 2 and G age 3. A single Dolly Varden was captured at Site 1b upstream of Waterfall A. No fish were collected at Gage D-West or Gage D-East in August. Surface water in the mainstem HBC was not continuously connected during the August site visit. The stream channel was dry at a similar location observed during the July event between Gage 2 and Gage 3. The initial mile of HBC from the marine environment contained a substantial number of spawning adult salmon. Upon further investigation the spawning fish were identified as a combined run of pink and chum salmon (Photo D-5). None of these fish were able to make it above Gage 3 due to the dry channel bed upstream. In October 2014, minnow traps were set on the 7th and retrieved on the 8th. Soak times ranged from a maximum duration of 22 hours 29 minutes at the D-West sites to 20 hours 3 minutes at G2-3 (Table C.4). A total of 105 fish were collected from six different traps located at Gage 2 and Gage 3. Of the 105 fish, 39 were identified as coho salmon and the remaining 66 were Dolly Varden. The most productive trap was located at G3-2 in the mainstem reach of HBC which caught 33 fish. No fish were collected at Site 1b, Gage D- West, or Gage D-East in October. Most of the mainstem reach of HBC in October between Gage 2 and Gage 3 was dry with the exception of isolated pools, including two pools located near Gage 3. One isolated pool in particular contained an estimated 30–40 adult coho salmon and several XY XY #I #I !5 #I #I #I [¡ [¡ [¡ !( !( USGS No. 15297100 USGS No. 15297110Te r r o r L a k eEastForkHiddenBasinCreekMiddleForkHiddenBasinCreekWestFork HiddenBasin Cre e kEastForkUpperHiddenBasinCreekWestForkUpperHiddenBasinCreek Hid d e n BasinCreekH I D D E N B A S I N B A Y D-West D-East G3 G2 1b DE DW Waterfall A Waterfall B Gage 3 Gage 2Field Discharge Site 1b Gage 1 Gage D-East Gage D-West M:\GIS\0197228_KEA_Hidden_Basin_Hydro_Study\mxd\2014_Report\3_9_HBC_Fish_Sampling_Locations.mxdHBC Fish Sampling Locations Sampling Results [¡Anadromous & Resident Fish [¡Resident Dolly Varden !(No Fish Captured #I ERM Gages !5 ERM Discharge Site XY USGS Gages UHB Proposed Diversions National Hydrography Dataset Lake/Pond Ocean Streams HBC Intermittent Reach Hidden Basin Creek, Kodiak, Alaska Source: A WMS-compliant map server provided by the Alaska Mapped program (http://www.alaskamapped.org) and UAF-GINA (http://www.gina.alaska.edu).

On October 7, 2014, the pool was filled with live fish. Upon return on the October 8, 2014, 13 dead coho salmon were observed and the pool size had decreased substantially causing crowding for the remaining fish. Based on field observations, it appears that juvenile fish use the mainstem reach of HBC as rearing habitat, finding refuge at creek margins, in pools and areas of low velocity. During periods of high flow or sufficient water depth adult spawning fish migrate upstream at least to the location of Gage 3, but infrequently if at all upstream as far as Gage 2. No adult fish were observed further more than 200 ft upstream of Gage 3. Adult and juvenile fish become stranded in isolated pools when surface water flow decreases in the mainstem of HBC largely due to downwelling in the porous alluvial materials present between Gage 2 and Gage 3. These pools, if deep enough, provide fragmented overwintering habitat for juvenile fish. The reaches of HBC above Gage 2 contain marginal quality fish habitat due to the high gradient, lack of gravel substrate and limited cover. These reaches are fishless aside from a small resident population of Dolly Varden. The Dolly Varden collected at Site 1b likely colonized the reach during a period when sea levels were high enough to inundate the upstream fish barrier presented at Waterfall A. The resident Dolly Varden at Site 1b apparently adapted to the marginal habitat and are able to withstand being washed downstream during high water events. Site 1b provides the shallowest gradient available in Upper HBC which is predominantly comprised of steep riffles, plunge pools, cascades and waterfalls. The stunted adult Dolly Varden collected at Site 1b coupled with the depressed population indicates a lack of genetic exchange with populations located in the mainstem of HBC. As a result, Waterfall A likely serves as an upstream migration barrier for Dolly Varden located in the mainstem of HBC. No fish were captured or observed upstream of Waterfall B downstream from Gage D-West and Gage D-East suggesting Waterfall B continues to present a barrier to upstream fish passage. It is well documented that Dolly Varden exist in two forms – anadromous and resident (Jonsson and Jonsson 1993). In some cases the resident form is found upstream of a natural barrier that prevents upstream movement of the anadromous form (Ihlenfeldt 2005). Resident forms are not always isolated, however, and their distribution may overlap that of the anadromous form found downstream. Upstream passage barriers may result in isolated populations of resident forms. Limited movement longitudinally may be related to a combination of gradient and discharge combined with physical barriers in Upper HBC. In an unpublished Forest Service Study of fish movement, including Dolly Varden, in relation to stream stage it was discovered that few fish move at very low stream stages (Bryant and Luckey 2004). Other results suggested that movement of Dolly Varden (< 170 mm in fork length) decreased substantially as stream stage increases beyond 1.0 ft and ceases altogether above 2.0 ft (Bryant and Luckey 2004). Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 42 2/11/2015 Resident Dolly Varden prefer spawning areas at the edges of pools in low velocity water with a gravel substrate of 1-4 cm (Ihlenfeldt 2005). Cover (large woody debris, rocks), overwintering areas and low-velocity areas are all important factors to the survival of a resident Dolly Varden population (Ihlenfeldt 2005). It appears these conditions are met, at least marginally, by the stream reaches upstream of Gage 2. If the proposed Upper Hidden Basin Diversions are built it may improve Dolly Varden habitat above Waterfall A by ameliorating the impacts of high flow and high stream velocity during flood events. Instream flows downstream of the proposed diversions will be derived from tributary inputs directly downstream of D-West Diversion continuing to increase longitudinally downstream at Sites 1b and Gage 2. Figure 3-9 illustrates the volume of water diverted at D-West and D-East as well as the tributary flow contributions directly downstream from the D-West diversion. In addition, peak flows in excess of the tunnel diversion capacity (~900 cfs) will be passed over the diversion structures into the section of Upper HBC downstream. Additional tributary inputs downstream of the diversions will contribute peak flows as well. Anadromous species have distinct life history stages (Figure 3-10) triggered by environmental cues such as discharge, water temperature and photoperiod (Bjornn and Reiser 1991). A summary of the life history requirements for coho and Dolly Varden is provided below. Coho salmon Coho salmon are a newly documented anadromous species to the AWC for HBC. The freshwater and overwinter habitat of juvenile coho salmon have been studied extensively (Ruggles 1966; Bustard and Narver 1975; Sandercock 1991; Ebersole et al. 2006; Giannico and Healey 1998; others). Juvenile coho salmon thrive in slow water, pool type habitat where they experience higher growth rates. Large body size confers a competitive advantage over smaller, slow growing conspecifics in the pursuit of food, and decreases predation by gape limited predators (i.e. Dolly Varden). Larger juvenile coho salmon are also better able to maintain their longitudinal position in streams and rivers than are smaller juvenile coho salmon that are vulnerable to downstream displacement due to floods (Giannico and Healey 1998) and competition for prime feeding areas (Ruggles 1966). The presence of pools and other low velocity meso-scale habitats have been demonstrated to increase freshwater residence time (Ruggles 1966), which increases individual size at the time of smolt emigration, and improves ocean survival (Ebersole et al. 2006). Coho salmon were captured in August and October in HBC in 2014. Juvenile coho salmon have a longer freshwater residency time (1 to 3 years) than either of the other two salmon species present in the mainstem of HBC (pink salmon and chum salmon). Pink and chum salmon fry begin to emigrate immediately downstream upon emergence. Based on their size at capture, two age groups of juvenile coho salmon were present in HBC in 2014: age zero, young-of year (YOY) coho salmon and age one coho salmon (fry that emerged in 2013). Juvenile coho salmon exhibit demersal ‘hiding’ behavior and are Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 43 2/11/2015 FIGURE 3-9: UPPER HIDDEN BASIN DIVERSION PROJECT FLOW COMPARISONS 050100150200250300350400450500Apr May Jun Jul Aug Sep OctDischarge (cfs)DateTotal Diverted Flow From Proposed DiversionsTotal Flow Below Diversion Dams Above Waterfall B Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 44 2/11/2015 capable of concealing themselves completely within stream substrate (Swales et al. 1986; Bustard 1986). They have also been documented to undertake both upstream and downstream migrations to and from overwinter and / or refuge habitat as juvenile pre- smolts. The fact that coho salmon were not captured in either the May or July sampling events suggests that the YOY size class had not yet emerged from the gravel or were too small at that stage to be captured, and that the age 1 size class had not yet moved upstream into the portions of HBC where minnow traps were set at Gage 2 and Gage 3. Age 1 coho salmon either wintered at the mouth of HBC or in the unnamed tributary drainages entering the mainstem of HBC. FIGURE 3-10. SALMON LIFE STAGE SUPERIMPOSED ON HBC HYDROGRAPH Dolly Varden The waterfall above Gage 2 (Waterfall A) has a major influence on fish distribution in Upper HBC. The 2014 minnow trapping efforts confirmed the existence of what is likely a small, isolated population of Dolly Varden. Resident Dolly Varden have distinct life stages triggered by environmental cues such as discharge (Figure 3-11). The resident form of Dolly Varden are well known to persist in waters above barriers similar to that observed in the West Fork of HBC. Throughout their range, Dolly Varden are often the only species present above fish migration barriers and likely benefit from the absence of competition for resources.

Low growth rate (Armstrong and Morrow 1980); 4. Genetic isolation (Currens et al. 2003). FIGURE 3-11. RESIDENT DOLLY VARDEN LIFE STAGE SUPERIMPOSED ON HBC HYDROGRAPH The degree of genetic isolation of this sub- population of Dolly Varden from resident and anadromous forms below the falls is not known and would require genetic testing to identify. It is conceivable that some fish located above the barrier falls migrate downstream leading to some mixing between the two populations in the mainstem of HBC (Bryant and Lukey 2004) but genetic exchange does not appear possible in an upstream direction. It has been suggested that the low number of eggs per female Dolly Varden in isolated populations naturally limits population size in these space and resource-restricted habitats (Blackett 1973). Dolly Varden in Alaska are typified by anadromous and resident forms. The anadromous forms overwinter in streams connected to lakes or in some cases overwinter in the ocean (Armstrong and Morrow 1980; Bernard et al. 1995). Using the pattern exhibited in the southern portion of their range in Alaska as a guide (Armstrong and Morrow 1980; Bernard et al. 1995), it is likely that anadromous Dolly Varden inhabit 0 100 200 300 400 500 600 700 800 Oct Nov Dec Jan Feb Mar Apr May Jun Jul Aug Sep Resident Dolly VardenMean Daily Discharge (cfs)Gage 2 / USGS No. 15297110 D-East and D-West Diversions Combined Spawning Intergravel Development Fry Emergence Outmigration Hydrographs Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 46 2/11/2015 the mainstem reaches of HBC during the salmon spawning seasons to feed on salmon eggs. Salmon eggs are likely a major food source for Dolly Varden in the mainstem HBC, judging from the high density of pink salmon and chum salmon spawning activity observed downstream of Gage 3. This food source is not available to the resident Dolly Varden population above the barrier hence the small size of fish captured there. Due to the richness of salmon eggs as a Dolly Varden food source, a portion of the mainstem HBC Dolly Varden population may remain as year-round residents and avoid anadromy altogether. There is an ecologically driven trade-off between the divergent life history patterns (Jonnson and Jonnson 1993) related to delaying maturity to maximize reproductive fitness (anadromous form) or maturing early and reproducing to avoid high ocean mortality (resident form). Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 47 2/11/2015 4. DISCUSSION Diversion of water in Upper HBC is not likely to have an impact on surface water in the mainstem of HBC downstream. The Upper Hidden Basin Diversion Project comprises only 15 percent of the overall HBC watershed area. The majority of the flow delivered from the West Fork of HBC manifests as subsurface flows in the mainstem. In addition, fish distribution in the mainstem of HBC is limited spatially and temporally by the lack of surface water continuity. Surface water discharge was monitored longitudinally in HBC in 2013 and 2014 using continuous recording pressure transducers combined with periodic site visits to measure discharge. The USGS installed and maintained two surface water gaging stations on the West Fork of HBC between 1982 and 1984. The USGS 15297100 data collected from 1982–1984 was compared to the discharge data collected at Gage 1 and Gage D-West in 2013 and 2014. The magnitude, frequency and duration of surface water discharge data from Gage 1 and Gage D-West data are comparable to discharge volumes recorded at USGS 15297100. The peak flows and elevated winter discharge observed in HBC for the 2014 WY was likely due to the increase in winter air temperatures in 2014 coupled with heavy precipitation events. The lower discharge during the mid-summer period in 2014 was likely due to the lack of mountain snow pack in the 2014 WY. The cumulative water yield available for delivery to Terror Lake from the Upper Hidden Basin Diversion Project for the 2014 WY is 29,585 ac ft. The D-West Diversion comprised 72%, 21,172 ac ft, of the water yield while the D-East Diversion delivered the remaining 28%, 8,413 ac ft. The proportion of surface water discharge contributed directly from the proposed Upper Hidden Basin Diversion Project to the anadromous reach of the lower HBC cannot be accurately quantified through surface water stream gaging alone due to the porous substrate in the mainstem of HBC causing flows to go subsurface. Several ungaged catchments also contribute surface water and groundwater to the mainstem HBC. The Middle and East Forks of HBC comprise substantial drainage areas along with several unnamed tributaries not accounted for in the surface water measurements alone. The Upper Hidden Basin Diversion Project comprises 15% of the entire HBC watershed, 3.8 mi2. The West Fork of HBC comprises 47%, 11.8 mi2. The Middle Fork and East Forks of HBC comprise an additional 19% (4.69 mi2) and 9% (2.2 mi2) respectively. The latter two forks of HBC were not gaged for this study and as a result, their proportional contribution was not accounted for at Gage 3 using the surface water measurements alone. An alternative approach was used to compare the proportion of discharge contributed from each headwater area in HBC by calculating the discharge based on drainage area size for each catchment. Mean daily discharge for USGS Gage 15297100 and 15297110 was used to synthesize hydrographs for the ungaged catchments in HBC for longitudinal comparisons of surface water yields. Surface water discharge in the synthesized hydrograph is typically 2.5 times greater at Gage 2 compared to discharge measures for the Upper Hidden Basin Diversion Project. Likewise, the synthesized discharge at Gage 3 is an additional two times greater than Gage 2 throughout the year. The addition of the Middle Fork and East Fork in the discharge yield analysis indicates the Upper Hidden Basin Diversion Project comprises a much smaller percentage of the overall water yield for Gage 3. The surface water data collected in 2013 and 2014 did not include the Middle and East Forks in the overall hydrology balance Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 48 2/11/2015 sheet. Surface water measures at Gage 3 in 2013 and 2014 also failed to quantify the contributions from the Middle and East Forks because much of the contribution from these catchments, like the West Fork, go subsurface and are not measurable using surface water sensors alone. Prior to this study effort, little was known about the fish habitat and use in HBC. The study succeeded in improving the local knowledge and understanding of fish distribution longitudinally in the drainage. The objective of the fish trapping program was to document the presence / absence of fish longitudinally in HBC. Wire-mesh minnow traps were used to sample juvenile and adults less than 200 mm at the four stream gage locations and Site 1b in HBC. Adult spawning fish distribution was documented using helicopter flights combined with ground observations. The lower three miles of HBC, the mainstem, is listed in the AWC and is known to support chum and pink salmon, as well as Dolly Varden. In 2014, minnow trapping efforts associated with this study confirmed coho salmon was another anadromous fish species inhabiting the drainage seasonally. Coho were not previously listed in the AWC for the mainstem of HBC. The results from the 2014 fish collection efforts have been presented to ADFG so the AWC can be updated to include coho. Fish were not present at Gage D-West or Gage D-East. Resident Dolly Varden were collected in small numbers (three individuals) at Site 1b on two out of four sampling efforts in 2014. Site 1b is located upstream of Waterfall A, a presumed barrier to upstream fish migration. No other fish species were observed upstream of Waterfall A. At Gages 2 and 3, juvenile coho, Dolly Varden, and sculpin species were observed throughout the four sampling events in 2014 (May, July, August, and October). Adult pink and chum salmon were observed in August 2014 in the mainstem of HBC downstream of Gage 3. In October 2014, adult coho and Dolly Varden were observed in the mainstem of HBC. No adult fish were observed more than 200 ft upstream of Gage 3. While renowned for their homing ability, salmon are also highly opportunistic and capable of exploiting marginal or newly available habitat for their various life stages (Healey 2009). The fact that portions of the mainstem HBC experiences discontinuous flow during late summer in some years suggests adult pink and chum salmon (and potentially coho salmon) make use of the system opportunistically for spawning under suitable flow conditions. Based on the prevailing gradient and substrate, most, if not all, of this opportunistic spawning likely occurs in the mainstem. Although the Middle, East, and West Forks of HBC have continuous flow, it is unlikely salmon spawn in them due to the steep gradient, large substrate (boulders) and presence of waterfalls a short distance upstream from the confluence with the mainstem. Spawning may occur at the mouth of the unnamed tributaries entering the mainstem, but the substrate size and presence of barriers upstream on these tributaries is unknown at this time. Fish occupying pools in the mainstem of HBC that are seasonally dewatered are not likely to survive the winter unless the pool has sufficient depth and food resources. As referenced above, during the majority of the time, the mainstem of HBC is dry between Gage 2 and Gage 3 with intermittent, disconnected pools. Based on field observations, the dry stream channel between gages 2 and 3 is the more normal condition. The anadromous and resident fish found in the mainstem of HBC have likely adapted to the stochastic nature of the surface water flows. Fish habitat between Gage 2 and Gage 3 is limited spatially and Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 49 2/17/2015 temporally. The dry stream channel in this reach presents a migration barrier for adults and juveniles. During storm events or periods of high run-off, fish may access the mainstem of HBC between Gage 2 and Gage 3 opportunistically but are likely to be trapped in pools with limited resources (dissolved oxygen, food) making them more vulnerable to disease, competition, and predation. Downstream of Gage 3, HBC appears to maintain surface water connectivity to the marine environment at Hidden Basin Bay. The longitudinal movement of anadromous and resident fish in the mainstem of HBC is largely restricted to the stream reaches with available surface water, namely the reach downstream of Gage 3. Water diversions at the Upper Hidden Basin Diversion Project are not likely to impact available fish habitat in the reach below Gage 3. The Upper Hidden Basin Diversion Project comprises only 15 percent of the overall HBC watershed area. Surface water flows downstream of Gage 3 are continuous.

Stream temperature monitoring coincided with establishment of stream gages at respective locations beginning in April 2013 at Gage 2 and 3 and June 2013 at Gage 1. Gages D- East and D-West were established on February 06, 2014 and May 16, 2014 respectively. Gage 1 was discontinued on July 14, 2014 due to installation of Gage D-West in closer proximity to the proposed diversion. Damage to Gage 2 from high flow events resulted in intermittent loss of temperature data. In 2013 and 2014, daytime water temperatures were typically warmer in the headwater gage locations (Gage 1, Gage D-West and Gage D-East) compared to the lower elevation gages (Gage 2 and Gage 3). Gage 1 exhibited the broadest annual temperature fluctuations in 2013 compared to Gage 2 and Gage 3 (Figure 1). In 2013, Gage 1 recorded the highest summer water temperatures of the three gages located longitudinally in HBC, 14.9 ◦C on August 24, 2013 (Table 1). In contrast, at Gage 2 and Gage 3 maximum water temperature in 2013 was 11.7 ◦C. In 2014, maximum water temperatures at Gage D-West and Gage D-East were 13.4 and 12.7 ◦C respectively, similar to temperatures recorded at Gage 1. Overall, Gage 3 exhibited the narrowest annual temperature fluctuation in 2013 and 2014 compared to the other gages in the watershed. Surface water flow at Gage 3 is derived primarily from groundwater upwellings just upstream from the gage location except during the peak of the snowmelt hydrograph in June and peak flows during large precipitation events. Stream temperatures in the proximity of groundwater upwelling zones are typically cooler than adjacent surface water and exhibit less fluctuation over a 24-hour period. To further examine stream temperatures, diel fluctuations at the respective gage locations five different 48-hour periods occurring in July and August of 2014 were analyzed. On July 2-3, 2014, Gage 1 located in the headwaters displayed the lowest stream temperatures both day and night compared to the other four gages located further downstream (Figure 2). These low daytime stream temperatures in early July were likely influenced by the close proximity of melting snow. Gage D-West, Gage D-East and Gage 2 all exhibited similar daily maximum temperatures close to 10 ◦C. In contrast, Gage 3 daily maximum was only 8.2 ◦C and had the narrowest diel temperature fluctuation (2.8 ◦C) compared to the other four gages (Table 2). On July 20-21, 2014, diel temperature fluctuations were again more pronounced at Gage D-West, Gage D-East and Gage 2 compared to Gage 3 (Figure 3). The diel temperature range at Gage 3 was 1.4 ◦C during this 48-hr period (Table 3). The Gage 3 maximum temperature during the July 20-21 period was 7.9 ◦C, 4.6 and 3.8 ◦C less than Gage D-West and Gage D-East respectively. On August 3-4, 2014, the contrasts in diel stream temperature fluctuations between Gage 3 and the upstream gages were even more pronounced than July (Figure 4). The daily maximum temperature at Gage 3 was 8.0 ◦C compared to 10.8, 10.4 and 11.1 ◦C at Gage D-West, Gage D-East and Gage 2 respectively. On August 17-18, 2014, diel fluctuations in stream temperatures at Gage 3 exhibited similar but slightly lower values as those at Gage D-West, Gage D-East and Gage 2 (Figure 4). The maximum stream temperature at Gage 3 was 10.0 ◦C Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 2 6/15/2015 (Table 5), substantially greater than other 48-hour periods. The increased stream temperature at Gage 3 August 17-18, 2014 might be due to increased surface water discharge from precipitation falling August 7-16, 2014. Stream temperatures recorded on August 17-18 were likely a reflection of the surface water flows between Gage 2 and Gage 3 overwhelming the water temperatures at Gage 3 typically associated with groundwater. Surface water discharge on August 17 at Gage 3 was 187.9 cfs compared to discharge of 3.1 cfs on August 3, 2014 when differences in stream temperature between Gage 3 and upstream gages were most pronounced. On August 20-21, 2014, Gage 3 stream temperatures were again substantially lower compared to Gage D-West, Gage D-East and Gage 2 (Figure 6). Maximum stream temperature at Gage 3 was 9.2 ◦C compared to 12.4, 12.2 and 11.5 ◦C at Gage D-West, Gage D-East and Gage 2 respectively (Table 6). Analysis of the 48-hour time periods during the summer months indicates that Gage 3 maximum stream temperatures are substantially lower than upstream gage locations except when continuous surface water discharge between Gage 2 and Gage 3 occurs during high precipitation events. The dates selected for the 48-hour periods correspond to the warmest days recorded for the months of July and August, 2014 in Kodiak, AK (Source: http://www.usclimatedata.com/climate/kodiak/alaska/united-states/usak0133). July 2-3 and July 20-21 were the warmest recorded in the City of Kodiak for the summer 2014 (Figure 7). August 2014’s warmest 2-day periods were Aug 2-3 and 17-18. The 2-day period of August 20- 21 was also warm, but not the hottest (Figure 8). Hidden Basin Creek Hydrology and Fisheries Report KEA ERM 3 6/15/2015 FIGURE 1.

INTRODUCTION Kodiak Electric Association (KEA) operates the Terror Lake Hydroelectric Project located approximately 20 miles southwest of Kodiak on the Kizhuyak River. The Terror Lake Hydroelectric Project produces 80% of KEAs electric generation capacity. Water is diverted from the Terror Lake reservoir to the generation plant through an approximately 5-mile-long power tunnel. KEA is proposing to divert additional water from Upper Hidden Basin Creek (UHBC), the drainage to the east of Terror Lake (Figure 1). The diverted water would supplement Terror Lake’s water supply and be used to generate power from KEAs existing Terror Lake Hydroelectric Project (FERC Project No.2743). The proposed diversions would require the construction of an approximately 3 mile long road to access the proposed diversion sites. The road would extend from the existing Terror Lake access road, south to the proposed diversion sites (Figure 1), requiring a Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers (USACE) to place fill into any Waters of the U.S. (wetlands and waters) crossed by the proposed road. Therefore, KEA requested a preliminary assessment of potential wetlands and waters along the potential route that might be subject to a USACE Section 404 permit. This report provides a preliminary assessment of wetlands and waters along the potential road corridor. It is intended to be a cursory assessment with the purpose of guiding initial engineering designs. It is not a formal delineation of wetlands and waters. 1.1. Study Area The study area includes the area between the existing Terror Lake access road in the north, and the proposed diversions (D-East and D-West) in the south (Figure 1). All locations between the steeper valley walls were considered potentially suitable for placement of the access road.

METHODS The preliminary wetlands and waters assessment employed a three step approach: 1) GIS-based desktop pre-mapping; 2) field groundtruthing using visual observations; and 3) GIS-based post-field editing of the desktop pre-mapping. In an effort to guide the desktop mapping a 2000 foot wide mapping corridor was created in ArcGIS using a topographic map. This mapping corridor roughly followed the valley floor (Figure 1). A wetland scientist completed the desktop pre-mapping within the mapping area by manually digitizing all potential wetland or waters features in ArcGIS. The following base layers from the Geographic Information Network of Alaska (GINA, www.gina.alaska.edu) were used to digitize the wetlands and waters: the best available true color aerial orthoimagery, National Hydrography Data layer (NHD), U.S. Fish and Wildlife Service National Wetlands Inventory (NWI) layer, georeferenced topographic maps (100 foot contours), and a hillshade layer displaying terrain contours. Digitized wetlands and waters polygons were classified using the NWI wetlands classification system (Cowardin et al 1979). Two ERM scientists conducted the field groundtruthing of the wetlands and waters pre- mapping on July 17, 2014. They walked from north to south, observing all of the polygons that identified in the pre-mapping exercise. Observations were documented using a handheld GPS unit, photos, field notebook, and edits drawn on the field maps. The field-based observations were then used to update the wetlands and waters mapping in ArcGIS. “Wetlands” were defined as any area with greater than 30% vegetation cover, that lacked a bed and bank, and ordinary high water mark (e.g. non- stream areas), and possessed wetland vegetation (as defined by the USFWS National Wetlands Inventory plant list) and any observable wetland hydrology or hydric soils. Soil pits were not dug during this preliminary investigation. “Waters” were defined as areas having less than 30% vegetation cover, with a distinct channel bed and bank, and indications of an ordinary high water mark (OHWM). Linear features too narrow to be mapped as polygons in ArcGIS (e.g. less than 15 feet wide, including narrow stream channels) were mapped as line features. All other wetlands and waters were mapped as polygons. This resulted in two GIS geodatabase feature classes, polygons and lines. Note that given the lower resolution of the aerial imagery, especially at the southern end of the mapping corridor where the imagery was of very poor resolution, it was not always possible to accurately map potential boundaries in the desktop phase. Further, the field effort was not intended to provide comprehensive groundtruthing and delineation of the entire potential road corridor; rather it was intended to provide a cursory groundtruthing effort suitable for preliminary engineering planning of the road alignment. As such, every effort was made to be conservative towards including questionable area as a wetland or water, rather than excluding it. Lastly, because the purpose of this report was to provide a cursory assessment as part of developing the potential road alignment, total area or linear feet of wetlands and waters was not calculated nor tabulated as part of this report. Wetlands and waters will instead Upper Hidden Basin Creek Access Road Preliminary Wetlands and Waters Assessment KEA ERM 3 8/4/2014 be delineated and quantified as part of the formal wetland and waters delineation for Section 404 permitting for the project. Upper Hidden Basin Creek Access Road Preliminary Wetlands and Waters Assessment KEA 3. RESULTS The ERM field team walked the length of the mapping corridor, from the Terror Lake Access Road in the north, south to the proposed East and West diversions located on Upper Hidden Basin Creek. They were able to groundtruth and confirm potential wetlands or waters for each of the desktop-mapped wetlands and waters polygons on the preliminary field maps. Results of the post-field mapping are presented in Appendix A, Maps 1-6. Due to the poor aerial image resolution at the southern end of the mapping corridor, most of the area depicted on Map 6 was mapped as a single large wetland polygon. This area is likely a mosaic of wetland and non-wetland areas that (as with most of the mapping corridor) will require detailed wetland delineation. Table 1 presents the single wetland type, and the three different waters types that were identified within the wetlands/waters mapping area, as defined by Cowardin et al. (1979). The wetland type was palustrine emergent/scrub shrub, characterized by herbaceous vegetation and low or dwarf shrubs. These wetlands were located along the stream corridors (Figure 2), or as depressional bogs/marshes (Figure 3). Three types of waters were identified, riverine intermittent stream bottom (Figure 4), riverine upper perennial unconsolodated bottom (Figure 5), and palustrine unconsolodated bottom (ponds) (Figure 6). The riverine water channel types were either deep incised canyon channels (Figure 7), alpine rivulets (Figure 8), or braided gravel bed streams (Figure 9). Ponds were typically very fine sand or silt substrate, many of which were dry at the time of the field survey (Figure 10). TABLE 1.

The State of Alaska reserves the right to require additional coverage if, in its discretion, it determines that it may be warranted. Any changes in the approved permit development and operations plan, or the existence of significant claims against the liability coverage, would warrant examination of the insurance by the state to determine adequacy. e) In the event the Permittee becomes aware of a claim against any of its liability coverage, the Permittee shall notify, and provide documentation and full disclosure of the claim to the Southcentral Regional Manager within 20 days.

(KEA), licensee for the Terror Lake Hydroelectric Project, FERC No. 2743 (Project), proposes to file an Application for Amendment to License with the Federal Energy Regulatory Commission (FERC) to enable the construction of the Upper Hidden Bas i n Diversion. The proposed Upper Hidden Basin Diversion is a new diversion in a location where there is no existing dam or diversion; therefore, KEA seeks to engage in the consultation requirements as per 18 CFR 4 .38. The proposed Upper Hidden Basin Diversion is located in the mountainous uplands of Kodiak Island, Alaska , at approximately 57" 36' 30" North, 153• 0' 10" West. Enclosed are maps illustrating the project lo cat ion and conceptual design layout. This new diversion would supplement the available water supply for the existing Project by ca pturing additional snow melt and rain in the upp er reache s of the Hidden Basin watershed and conveying it westward through a mountain ridge to the existing Terror Lake reservoir. Structural components for th e proposed diversio n would consist of two dam embankments co nnected by an approximately 0.6 mile long conveyan ce pipe, a 1.2 mile lon g subterranean tunnel to the Terror Lake reservoir, and a 4 mile long gravel road for construction and future maintenance access. The diversion components would be a basic, non-mechanical design intend e d for un-manned water conveyance. Once the additional water re so urce from the Upper Hidden Basin Diversion flows into the Terror Lake reservoir, hydropower would be generated from the existi ng Project powerhouse and fed directly into KEA's existing grid without any operational changes or any other capacity-related modifications . Thi s new diversion would enhance the existing Project and allow KEA to provide a continuous su pply of renewable energy to the communities of Kodiak as electrical demand co ntinues to grow. In a letter dated April17, 2015, FERC de signated KEA as their non-federa l r epresen t ative for the purpose of conducting informal consultation with the US Fish and Wildlife Service (USFWS) pursuant to the regulation s at SO CFR 402 .08 implementing Section 7 of the Endan ge red Sp ecies Act (ESA). KEA here in requests a copy of the current species list for the Upper Hidde n Basin Diversion area . Specifically, KEA is requesting information on federally endangered or threatened plant and animal species, as well as pl ant and animal sp ecies of concern that are known or susp ect ed to occur in the project area. If possible, it would be very helpful if your office could provide mapped locations of known occurrences of these species and designated critica l habitats, if any, for such species in the region of this project.

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 ). Please note thatet seq. candidate species are not included on this list. We encourage you to visit the following website to learn more about candidate species in your area: http://www.fws.gov/alaska/fisheries/fieldoffice/anchorage/endangered/candidate_conservation.htm New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 ), Federal agencies are requiredet seq. to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 ), and projects affecting these species may requireet seq. development of an eagle conservation plan (http://www.fws.gov/windenergy/eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats. Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm; http://www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/comtow.html. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

I have discussed this project with NMFS' Division of Protected Resources. There are no species under NMFS jurisdiction and listed as endangered or threatened under the Endangered Species Act that are known or suspected to occur in the project area, nor is there designated critical habitat for any such species in the project area. This precludes the need to consult informally with NMFS under Section 7 of the ESA for development of KEA's proposed Upper Hidden Basin Diversion into the Terror Lake Hydroelectric Project, FERC Project No. 2743. Thanks too for sharing the online tool of the USFWS for obtaining species lists. I've shared that with PRD and perhaps NMFS could in the future develop a similar tool to streamline project planning and consultation. Please let me know if there is anything more KEA requires for this project from NMFS.

KEA is a rural electric cooperative that provides electricity to approximately 5,900 meters on  Kodiak Island, Alaska in a service area that includes the region in and around the City of Kodiak,  the US Coast Guard Base, Bells Flats, Chiniak, Pasagshak, and Port Lions.  KEA is a not‐for‐profit  501(c)(12) cooperative organized under AS 10.25 for the purpose of supplying electric energy

Hydropower generated by the Terror Lake Hydroelectric Project is KEA’s primary energy source.   Enhancing water availability to Terror Lake with a new water diversion allows KEA’s future  electrical load growth to be continually powered with renewable energy.  The proposed Upper  Hidden Basin Diversion would supplement the available energy resources for the Terror Lake  Hydroelectric Project by conveying water from the upper reaches of the Hidden Basin  watershed to the existing Terror Lake reservoir.  Once the supplementary water from the Upper  Hidden Basin Diversion flows into the Terror Lake reservoir, more renewable hydropower can  be generated from the existing Terror Lake Hydroelectric Project and fed directly into the KEA  grid.  KEA’s existing powerhouse and electrical grid infrastructure is able to deliver the  additional power to the Kodiak community without any modifications.      The existing Terror Lake reservoir is located in the remote north central area of Kodiak Island,  approximately 30 miles southwest of the City of Kodiak.  The proposed Upper Hidden Basin  Diversion project area is located east of the Terror Lake reservoir on the other side of a  mountain ridge.  This mountain ridge between Terror Lake and the Upper Hidden Basin  watershed serves as the boundary for Federal and State land.  The Terror Lake reservoir is on  Kodiak National Wildlife Refuge lands, and the proposed diversion project is on State lands.   Public use of the area is extremely minimal.    The general location of the easement request is approximately 57⁰ 35’ 37” N; 153⁰ 0’ 59” W.   Attached is a Site Location Map.  The proposed diversion area straddles the edges of USGS  Quadrangle Maps Kodiak C‐3 and C‐4.  A merged version of both USGS maps (scale of 1:  1:63,360) is provided to show the approximately easement request location, noted in blue.  The  exact size and location of the requested easement are approximate at this stage of project  development.  Additional surveying and mapping activities will be conducted in 2015 to define  the exact acreage of State land to be occupied by the proposed project.  That information will  be provided to DNR when it becomes available.       Attached are photographs of the proposed easement area.  This mountainous terrain is  typically inundated with snow from October to June.  Ground cover ranges from bare bedrock  and unconsolidated colluvium to palustrine emergent wetlands and scrub shrub.  There are no  trees in this upland, alpine area.  Access to this remote site is provided by helicopter, or by  backcountry hiking from the existing Terror Lake Hydroelectric Project access road.  The existing  Terror Lake Hydroelectric Project access road is a remote road used exclusively for KEA’s official  use for the operation and maintenance of the existing Terror Lake Hydroelectric Project, and it  is accessible only by floatplane, boat, or helicopter.  Attached is a photograph of the existing  Terror Lake Hydroelectric Project access road and the area where a new diversion access road  would be sited.      Attached is a conceptual layout of the proposed Upper Hidden Basin Diversion.  It is a basic,  non‐mechanical conveyance of water, with spur road accessibility.  Site development would  consists of 4 miles of a pioneer gravel road connecting the existing Terror Lake Hydroelectric  Project access road to two small dam embankments.  The eastern dam embankment (D‐East)  would convey water to the western dam embankment (D‐West) through a buried 0.4 mile pipe.   From the D‐West location, the water would be conveyed to the existing Terror Lake reservoir  through a 1.2 mile subterranean tunnel running underneath the mountain ridge.      This project is currently in the development phase.  To assess the quantity of water available for  diversion, KEA is currently collecting stream gauging data in this watershed as authorized by  Land Use Permit LAS 29042.  The final engineering design for the temporary and permanent  structures, the exact construction methods, and defined inventory of construction equipment  needed to build the road, diversion dams, conveyance pipe and tunnel are not yet determined.   It is KEA’s intent to finalize the engineering design and secure construction contacts in 2018,  initiate construction in 2019, and operate the new diversion by 2020.  The as‐built diversion  and access road will not generate, use, store, transport, dispose of or otherwise come in  contact with toxic and/or hazardous materials.  The as‐built diversion will not involve any  storage tanks, either above or below ground.  There would be no machinery left on site when  construction activities are complete.      The Terror Lake Hydroelectric Project is a federally licensed hydropower facility as Federal  Energy Regulatory Commission (FERC) Project No. 2743.  Adding the Upper Hidden Basin  Diversion to the Terror Lake Hydroelectric Project requires a FERC License Amendment, which is  a formal process of coordinated multi‐agency consultation and public scoping.  Through this  multi‐year FERC License Amendment process, KEA will be refining the diversion project design,  working with stakeholders to identify potential resource impacts, and developing project‐ specific plans and measures to minimize potential impacts.  The Alaska Department of Natural  Resources (DNR) is a key stakeholder in KEA’s FERC License Amendment process.  As the Upper  Hidden Basin Diversion design develops and more information becomes available, DNR will be  notified and provided with that information.    Ka rl u k L ar se n Ba y Ak h i o k Ol d Ha rb o r Pa sa g h a k Ch i n i a k Ko d i a k Ou z i n k iePort L i o n sShelikof St r a i t G ul f of A l a

Completed Application for Water Right Form for the headwater tributaries to Upper Hidden  Basin Creek;   2. FERC License No. 2743, which serves as the possessory interest document for the Terror Lake  Hydroelectric Project, which is where the water will be used;   3. Completed Application for Easement filed with DNR on April 15, 2015 requesting legal access to  the water withdrawal point;   4. Upper Hidden Basin Diversion conceptual project layout drawing;   5. USGS Quadrangle Maps Kodiak C‐3 and C‐4 indicating the location of the headwater tributaries  to Upper Hidden Basin Creek to be diverted; and  6. Hidden Basin Creek Hydrology and Fisheries Technical Report, prepared by ERM in February  2015.    There are items listed in the form’s instructions that are not applicable to this project, and therefore are  not provided.  The Upper Hidden Basin Diversion is a surface water diversion project; therefore there  are no drilled wells associated with the project.  There is no ADEC water or wastewater system  certificate associated with this project.  The headwater tributaries to Upper Hidden Basin Creek area not  anadromous water bodies identified or specified under AS 16.05.871(a); therefore a fish habitat permit  is not applicable.  The Upper Hidden Basin Diversion is not fully developed; therefore a notarized  Upper Hidden Basin Diversion Application for Water Right Page 2 of2 Statement of Beneficial Use of Water form and associated fee is not available. Alaska withdrew from the National Coastal Management Program under the Coastal Zone Management Act and no longer has an Alaska Coastal Management Program (ACMP) as of July 1, 2011; therefore a Coastal Project Questionnaire is no longer applicable. KEA is willing to provide a non-refundable fee for processing this applicati on; however the fee for hydroelectric power generation is not yet defined. As was discussed during our pre-filing consultation meeting on April10, 2015 and on our phone conversation on May 4, 2015, the application fee for this specific water use will be determined after KEA's application is deemed complete. Thank you for providing guidance on how KEA may receive timely water use authorization from the DNR for the development, construction and operation of the Upper Hidden Bas i n Diversion project.

Kodiak Electric Association, Inc. (KEA), licensee for the Terror Lake Hydroelectric Project FERC  No. 2743 (Project), is responsible for notifying the public of potential public safety hazards  within the Project area.  In accordance with 18 CFR §12.4 and §12.42, this document serves as  KEA’s Public Safety Plan.       Project Description  The Terror Lake Hydroelectric Project is the primary source of electricity for KEA’s service area  on Kodiak Island.  It is a remotely‐located, trans‐basin hydropower development that captures  water from the Terror River drainage and transports it by means of an un‐pressurized tunnel to  a powerhouse located in the Kizhuyak River valley.  Power is transmitted to the City of Kodiak  by 17‐mile long transmission line that crosses over a mountain pass.  The Project is the only  development in the area, and is accessible only by floatplane, boat or helicopter.       Within the Project boundary, there are 15 miles of gravel road beginning at the Project’s  dock/jetty area located at the head of Kizhuyak Bay and ending at the Terror Lake reservoir  located up in the mountains.  This Project access road is not connected to any other road  system on Kodiak Island, and all infrastructure associated with the Project is intended for  official use only.      The Terror Lake reservoir and dam are located within the Kodiak National Wildlife Refuge.   Infrastructure located within the vicinity of reservoir includes the main power tunnel’s intake  gate building and the outlet works valve house.  The Terror River valley downstream of the dam  embankment and outlet works valve house is completely undeveloped.      The Project powerhouse is located in the Kizhuyak River valley, approximately 5 miles northeast  of the Terror Lake reservoir. Infrastructure within the powerhouse area includes the substation,  staff housing, warehouse, and mechanic shop building.  The powerhouse contains three 11.25  megawatt turbine‐generator units, and each unit comprises a vertical shaft 6‐jet Pelton turbine  and synchronous generator. Two of these three units were authorized in the Original License  issued on October 5, 1981, and began commercial operation in 1985.  The third unit was  authorized in a license amendment issued on February 17, 2012 and began commercial  operation in 2013.      Public Use  No recreational facilities are located in the immediate Project area, and public use is essentially  non‐existent.  In correspondence dated June 17, 1997, the Commission exempted the Project  from filing the Hydropower Development Recreation Report (FERC Form 80) because of the lack  November 2013

215 Mission Rd., Suite 101  Kodiak, Alaska 99615  Phone (907) 486‐7004      This Memorandum of Understanding (MOU) pertains to the collaborative partnership between Kodiak  Electric Association, Inc. (KEA), Afognak Native Corporation (ANC) and the Alutiiq Museum &  Archaeological Repository (Alutiiq Museum) to conduct periodic monitoring of KOD‐190 through the  Alutiiq Museum’s Site Stewardship Program.       Archeological Site KOD‐190 has been interpreted to be a seasonally occupied fish camp eligible for  inclusion in the National Register of Historic Places.  Based upon KEA’s consultation with the State  Historic Preservation Office (SHPO) under Section 106 of the National Historic Preservation Act, periodic  monitoring of this site through the Alutiiq Museum’s Site Stewardship Program has been approved as an  appropriate measure for monitoring the condition of the site to identify any adverse effects to this  historic property, should that occur.     KOD‐190 is located on land owned by the ANC; it is not within KEA’s Terror Lake Hydroelectric Project  boundary.  Therefore, access to the site must be granted by ANC.  This MOU serves as written  permission from ANC for KOD‐190 to be included in the Alutiiq Museum’s Site Stewardship Program.       The Site Stewardship Program is administered by the Alutiiq Museum.  As partners in this program, a  Registered Professional Archeologist from the Alutiiq Museum will train KEA and ANC representatives in  May 2011 to act as site stewards.  By training staff from both organizations, representatives of either  ANC or KEA would be able to complete an annual site evaluation and report the results to the Alutiiq  Museum for inclusion in the Program Report.  It is the intention of ANC that their organization be  responsible for the periodic monitoring work in future years; however, if ANC representatives are  unable to conduct the work in a future year, then KEA representatives can step in to ensure continuous  monitoring each year.      It is the intention of all parties to continue this arrangement as long as the Site Stewardship Program  exists and all parties desire the collaboration.  For the purpose of administering this agreement, the  term of the MOU shall be for a period of ten years, expiring in the spring of 2021, dependent upon the  Alutiiq Museum’s continuation of their Site Stewardship Program.  If the Alutiiq Museum’s Site  Stewardship Program ceases to exist, then this agreement shall be terminated.       Any party may cancel this agreement by providing a 30‐day notice in writing.     Based upon KEA’s consultation with the SHPO, Howard Valley of ANC, and Amy Steffian of the Alutiiq  Museum, this MOU establishes the following responsibilities for each party.      Kodiak Electric Association:  • Obtain written permission from the Afognak Native Corporation for KOD‐190 to be included in
