This Supplemental Report is intended to provide the essential elements of the Preliminary Design Report for agency review and management decision making. The results of the analysis and 65 percent level Preliminary Design are presented in the detailed report. It is anticipated that a Non-Capacity Amendment to the Bradley Lake Project License (FERC No. P-8221) will be filed with the Federal Energy Regulatory Commission (FERC) by the Alaska Energy Authority (AEA) for the proposed diversion project. 2 SUMMARY This Supplement to the Preliminary Design Report for the proposed Battle Creek Diversion project summarizes the basis for the design of a diversion structure to be placed in the West Fork Upper Battle Creek, the associated conveyance structure(s) to conduct diverted flows to Bradley Lake and roads to support construction and maintenance. It is the intent of the Battle Creek Diversion Project to collect all surface drainage from precipitation draining from the intercepted slopes and drainages between the West Fork Upper Battle Creek and the existing Upper Battle Creek Diversion to Bradley Lake. The project will provide an additional water source for the Bradley Lake Hydroelectric Project by diverting water from the adjacent Battle Creek watershed that presently drains to the central portion of the Battle Creek basin and flows west to Kachemak Bay. Specifically, the design capture area is the area drained by the West Fork Upper Battle Creek and the area intercepted by the proposed conveyance canals from the diversion site to the existing Upper Battle Creek Diversion to Bradley Lake. According to a report by Stone and Webster dated December 20, 1990, the average energy value of the additional water diverted to Bradley Lake is approximately 975 kW-hr / Acre-Foot of water. This value varies depending on many factors, one being the Bradley Lake surface elevation. Based on analysis using USGS Water-Resources Investigations Report 93-4179, the rainfall specific to this basin ranges from 46,150 to 70,100 Acre-Feet per annum. Approximately 92% can be captured for power generation based on diversion operation from May through October each year. Assuming a value of $0.069/kW-hr, this yields an estimated value of the water diverted to Bradley Lake by the Battle Creek Diversion Project in the range of $2.9 to $4.3 million per year, depending on the weather cycle. 3 LOCATION The proposed Battle Creek Diversion Project is located on the south end of the Kenai Peninsula near the Bradley Lake Dam, which is the impoundment structure for the Bradley Lake Hydroelectric Project. R&M CONSULTANTS, INC. 4 Summary Level Supplement to Preliminary Design Report Water flows from an intake at the Bradley Lake Dam through a power tunnel to the powerhouse located on the south shore near the head of Kachemak Bay. There are no roads connected to the local or State highway system, thus access to the facility is limited to aircraft or marine vessels. Personnel travel to the site is generally by air from Homer airport 21 miles away. 151°30,000'W__151°23,000'W__151°16,000'W__151°09,000'W _151°02.000'W __150°55,000'W _150°48.000'W _150°41.000' W__ WGS84 150°30.000' W 59°50.000' N 59°47,000' N 2 2 8 g 8 & a '59°35.000' N '59°35,000' N 151°30.000" . . .000" 151°02.000'W —-150°55.000'W —-150°48.000' W —150°41.000' W__ WGS84 150°30.000' W NATIONAL —— “= GEOGRAPHIC Re 1yayin Figure 3- 1 General Location Map R&M CONSULTANTS, INC. 5 Summary Level Supplement to Preliminary Design Report 4 PROJECT DESCRIPTION 4.1 General The feasibility study/preliminary design identifies: e Anappropriate diversion point in the West Fork Battle Creek, The most efficient alignment for the conveyance canals, Appropriate access routes for construction/maintenance roads, and, Rough Order of Magnitude estimated cost of survey, geotechnical evaluation investigations, final design, construction management and construction of the proposed facilities. 4.2 Physical Structures The diversion dam and canal head works structure on the West Fork of Upper Battle Creek will be constructed of reinforced concrete and will include spill and control crest gates such as the commercially available Obermeyer Gate. This design has minimal moving parts and no mechanical operating systems. A jib crane will be provided on the crest of the dam for handling stoplogs and for use in maintenance/repair of the Obermeyer crest gate and general maintenance hoisting operations. A small service/utility building located just downstream from the dam at the left abutment area will house the air compressor, electric power and communications equipment appurtenant to the diversion dam , and canal head works gates and instrumentation. The total length of the canal is approximately 9,000 feet and comprises two sections; an upper canal and a lower canal. The upper and lower canals will be constructed at a relatively flat channel slope. The upper canal will discharge to a canal transition section comprised of an overland chute/cascade over a natural steep slope with a drop of approximately 350 feet from the upper canal to the lower canal. The energy of the flowing water will be dissipated and controlled at a stilling basin/control structure before it enters the lower canal to flow on to Bradley Lake. The canal transition section over the natural rock slope surface may require a minor amount of remedial rock excavation down the natural rock slope to ensure the water flows where intended. The canal sections will include strategically places stop-log structures to allow isolating areas within the canal sections for maintenance and repair. 4.3 Operation of Diversion Water will be diverted by the diversion dam into the upper canal. Stream flows at the diversion dam that exceed the canal capacity will be allowed to flow through the spillway by lowering the Obermeyer gate . Sluicing accumulated bedload from the forebay will be accomplished by opening the sluice gate from time to time during higher flows. The spillway may be operated to remove upper layers of accumulated bedload as well. Flow into the upper canal will be regulated by the canal inlet Obermeyer gate. At the Stilling Basin accumulated sediment will be sluiced from the Stilling Basin by opening the sluice gate. Opening the Stilling Basin Obermeyer gate will allow the released flow to remove upper layers of accumulated bedload. Bedload will be discharged into Battle Creek to allow continuation of natural stream fluvial processes as the main Battle Creek flows to Kachemak Bay. The water diverted from West Fork Upper Battle Creek is glacial melt water and lower temperature water than that in the lower Battle Creek.

EAST FORK UPPER BATTLE CREEK — Is the branch of the Upper Battle Creek system that is nearest to Bradley Lake and is diverted to Bradley Lake via an existing diversion structure and natural channel. This diversion point is where the LOWER CANAL will discharge into the existing Upper Battle Creek Diversion conveyance channel to Bradley Lake. EXISTING UPPER BATTLE CREEK DIVERSION STRUCTURE — Is a structure at the bottom of the falls of the EAST FORK UPPER BATTLE CREEK that is currently diverting flows into Bradley Lake by way of a conveyance channel. This structure is the intended location of the LOWER CANAL terminus. LOWER CANAL - This is the portion of the diversion system that conveys water from the STILLING BASIN located in the MIDDLE FORK UPPER BATTLE CREEK to the EXISTING UPPER BATTLE CREEK DIVERSION tailwater pool. MIDDLE FORK UPPER BATTLE CREEK — Is located near the center of the project and is the feature selected to convey flows from the UPPER CANAL to the LOWER CANAL. OUTLET ACCESS ROAD -— Provides access to the EXISTING UPPER BATTLE CREEK DIVERSION STRUCTURE. This is the location where the EAST FORK UPPER BATTLE CREEK is diverted to Bradley Lake and where the LOWER CANAL discharges into the existing Upper Battle Creek diversion conveyance channel to Bradley Lake. SECONDARY DIVERSION CANAL - Is a smaller canal/collection ditch that will collect water on the escarpment below the UPPER CANAL and just above the DIVERSION ACCESS ROAD. STILLING BASIN — This structure helps dissipate energy generated from the change in elevation from the UPPER CANAL to the LOWER CANAL and conveys water to the LOWER CANAL inlet. STILLING BASIN ACCESS ROAD — Begins midway along the DIVERSION ACCESS ROAD and continues to the STILLING BASIN located in the MIDDLE FORK UPPER BATTLE CREEK. UPPER CANAL — Conveys water from the DIVERSION STRUCTURE in the WEST FORK UPPER BATTLE CREEK to the CANAL TRANSITION located in the MIDDLE FORK UPPER BATTLE CREEK. WEST FORK UPPER BATTLE CREEK — Is the fork of the UPPER BATTLE CREEK system that conveys the majority of the flows that will be diverted to Bradley Lake by the Project. It is in this fork that the DIVERSION STRUCTURE is to be located that diverts flows to the UPPER CANAL. R&M CONSULTANTS, INC. 8 Summary Level Supplement to Preliminary Design Report 5 HYDROLOGY The Kenai Peninsula is known for heavy rainfall and dramatic variability in climate over short distances and small changes in elevation. Micro-climates are common and can cause one area to receive heavy rains and snows, while another adjacent basin with different characteristicsremains drier and un glaciated. Figure 5-1 — Basin Boundaries shows the boundaries of the basins from which flow will be diverted to Bradley Lake. Figure 5-2 - Average Monthly Rainfall is developed from the records of the National Weather Service. The blue-colored bars indicate the months during which the diversion will operate, with virtually all flow from the West Fork of Upper Battle Creek above the diversion location and along the conveyance route being routed to Bradley Lake. Table 5-1 shows the 2-year precipitation event based on analysis by the USGS method and NRCS method for the areas shown on Figure 5-1.

The geotechnical investigations and final report from the Bradley Lake Dam construction have been used for preliminary design of the diversion project. A thorough understanding of the rock properties and structure will be necessary for successful design and construction. The rock structure and the characteristics of discontinuities within the rock mass are expected to be primary factors in the analysis of seepage and slope stability. A detailed rock mapping program covering the entire project area, along with boreholes and test pits at specific locations will provide the data necessary for final geotechnical design recommendations. The project is located in an area of steep, mountainous terrain, and receives high snowfall. Avalanches are likely in the project area. The potential impact to the diversion project will need to be evaluated. It is recommended that a detailed avalanche hazard assessment be performed. The assessment should include: e Mapping of potential avalanche areas; e The potential for avalanches to impact the proposed structures; e The potential for late season avalanches to impact operations. R&M CONSULTANTS, INC. 11 Summary Level Supplement to Preliminary Design Report 7 CONVEYANCE Conveyance of the diverted water will be by a system of canals constructed to lead from the diversion dam location to the existing Upper Battle Creek Diversion. The proposed canals are anticipated to be primarily in bedrock and will be constructed by drilling and blasting the bedrock for excavation of the channel. The design of the canal cross section takes advantage of the bedrock by using 0.25 to 1 side slopes. In case the canal cross section is fully or partially constructed in colluvium, the cross section will be modified to accommodate the foundation conditions. The canals will be suitably lined for whatever distance is required in colluvium between bedrock excavation sections. Calculated design flows for canal hydraulic design were developed using the USGS linear regression method. It is estimated that 92% of the flows will be available for capture by opening the canal system in mid-May and continuing operation until the end of October (See Figure 5-2 Average Monthly Rainfall). The Upper Canal has a design flow of 850 cfs based on estimated flows at the diversion dam which, for a fixed top width of the canal, requires a depth of approximately 8 feet (Figure 7-1). The Lower Canal has a design flow rate of 1,000 cfs to carry the primary diversion flows plus accretion from overland flows and minor stream interceptions along the lower canal route. This requires a channel depth of approximately 9 feet if the top width is maintained as 20 feet (Figure 7-2). These depths result in a velocity just over 6 feet per second at the design channel slope.

Access roads need to be constructed before the canals simply to gain construction access to the areas the canals will traverse. Some of the rock shot and excavated to construct the canals will be used to construct staging areas at the West Fork Upper Battle Creek Diversion Structure, Stilling Basin and Existing Upper Battle Creek Diversion sites. Most of the shot rock produced during canal excavation will be excess to the needs of the project. Where the slopes downhill of the canal are gradual enough for construction equipment to work safely, the excess shot rock will be consolidated directly downhill from the point at which it is excavated from the canal. On the steeper slopes, the excess shot rock will be dumped on the downhill side where it will come to rest on the existing talus slopes below exposed bedrock faces. R&M CONSULTANTS, INC. 15 Summary Level Supplement to Preliminary Design Report 8 DIVERSION STRUCTURE AND STILLING BASIN The West Fork Upper Battle Creek Diversion Structure consists of a concrete dam approximately 23-feet tall (maximum) with a 115-foot long crest at top elevation 1706 feet. The headworks structure includes a canal intake structure that will divert flows from West Fork Upper Battle Creek into the upper canal. The dam site was selected based on the canal horizontal and vertical alignment considering the minimum invert elevation for the canal profile, site topography to minimize excavation and concrete quantities, accessibility and flow diversion considerations during the construction period. Water control at the Diversion Structure is provided by a spillway with Obermeyer gate and a sluice gate for flushing sediment from the forebay of the dam. A separate bypass bay with stop logs is provided to allow for maintenance diversion of the stream flows away from the canal headworks and sluicing system. A jib crane is provided to use for maintenance and repair activities and to install and remove stoplogs. Flow into the upper canal at the headworks can be controlled by an Obermeyer gate located at the canal intake. The upper canal discharges into a confined channel (canyon-like) of the Middle Fork Upper Battle Creek, exits the confined channel into the canal transition area then flows on to the Stilling Basin. Before water reaches the stilling basin, it will flow through the canal transitiona area, a series of step-pools created by widening the channel cross section and lowering the channel invert. The steps will be created by leaving sections of the 6-foot wide incised channel and stacking boulders in the channel. Large shot rock will also be left in the pools as a means of creating additional turbulence and energy dissipation. The Stilling Basin diversion structure site was selected to balance the stilling basin excavation and diversion structure concrete volumes. After selection of the diversion structure location, the stilling basin was sized to contain the anticipated hydraulic jump that will be created by the flows passing down the confined channel of the Middle Fork Upper Battle Creek. R&M CONSULTANTS, INC. 16 Summary Level Supplement to Preliminary Design Report 9 ACCESS 9.1 General Road access to the Battle Creek Diversion Project will be from the existing Bradley lake Dam access road near the Bradley Lake Dam to a new access road system constructed to provide access to key locations in the diversion project. 9.2 Existing Roads The existing access road system at the Bradley Lake Hydroelectric project facility is open to pedestrian and non-motorized public access. Motorized access by personal vehicles and maintenance/construction equipment is restricted to facilities equipment operated by employees of HEA, or other authorized personnel. 9.3 Proposed Roads To allow for construction, maintenance and operations access to the diversion, 3.9 miles of new access roads will be constructed. The new access road begins at the existing Bradley Lake Dam Access road about 0.25 -mile west of the Bradley Lake Dam. The Project access comprises 3 road sections: e the Outlet Access Road begins at the existing Bradley Lake Dam access road about 0.25 mile from the dam and runs 1.0mile southeast to the existing Upper Battle Creek Diversion and the site of the lower canal outlet; e the Diversion Access Road begins at a point about 0.4-miles along the Outlet Access Road, for 2.5 miles southwest through the Battle Creek Valley, up the escarpment to end at the primary diversion site at elevation 1700 feet on the West Fork of Upper Battle Creek; e the Basin Access Road, a 0.34-mile long spur begins at a point about 1.5 miles along the Diversion Access Road and ends at the site of the Spilling Basin at the base of the transition from the upper canal to the lower canal. 9.4 Borrow Sites for Access Road Construction Material Approximately 20,000 cubic yards of shot rock will be needed to start construction on the Outlet Access Road. The old batch plant site approximately 0.5 mile west of Bradley Lake Dam will be designated, pending positive evaluation of the site by the geotechnical investigation, as the initial borrow site for road building material. As access road construction progresses, numerous cut sections in bedrock will be encountered. Again, pending positive geotechnical evaluation, each cut section in bedrock will be designated as a potential borrow site. The intent is that if suitable rock is present, the required minimum cut section for the access road can be enlarged to produce additional material for fill sections of the access road. R&M CONSULTANTS, INC. 17 Summary Level Supplement to Preliminary Design Report 10 PROJECT CONSTRUCTION WORK PLAN AND COST ESTIMATE 10.1 Work Plan Discussion In order to develop a sound cost estimate for the Battle Creek Diversion Project at the preliminary design level, work plans and operations sequencing were identified and evaluated to develop a plausible sequence of construction and construction equipment spread.. This sequence may not be the exact sequence any particular construction contractor develops or follows, however, the sequence presented herein is intended to illustrate a practical approach to accomplishing physical construction of the project in a reasonable time frame. Also, the means and methods assumed for the purposes of developing unit costs for the various work items may not be precisely the means and methods of any particular contractor. For purposes of work plan development and the preliminary construction estimate, means and methods were assumed that represent a plausible plan for accomplishing the work, based on the combined experience of the design team and construction engineers. The resulting preliminary cost estimate is considered to be within the range of costs that would be consistent with accepted modern construction practices. Based on historic experience obtained during the construction of the original Bradley Lake Hydroelectric Project, and operating and maintenance experience gained thereafter, the effective construction working season is assumed to begin by early June and run to the end of October. Additional working time in early summer may be gained by removing snow and opening the Bradley Lake Dam access road prior to early June; the costs vs. benefits of such activity are not included in this project work plan analysis and cost estimate. Likewise, the duration of the work season is dependent on the weather and a given contractor’s willingness to work into winter conditions, the onset of which can be estimated, but not predicted with certainty due to variable weather patterns. A major constraint on site clearing restrictions is the effect on migratory bird nesting habitat. For the Bradley Lake area, the “no clearing” window is generally May 1 through July 15, but could extend from as early as April 10 to as late as August 10, depending on habitat and species expected to be present. For the schedule presented in this report, the assumption is that required clearing will be done the season previous to the start of earthmoving activity, even if clearing is the only work done that previous season. 10.2 Construction Sequence By Season First season: e Construct access roads to Existing Upper Battle Creek Diversion, Stilling Basin Site, and new Diversion site. e Build access, pre-split and production blast and excavate Lower Canal. e Construct Stilling Basin and transition between Upper and Lower Canals. e Build access, pre-split and production blast and excavate Upper Canal. Second season: e Erect modular bridges (3). e Construct Diversion Dam and Headworks on West Fork Upper Battle Creek. e Complete blasting, excavation and grading to flowline grade on Lower and Upper Canals. e Install guardrail on access roads. e Produce and place sub-base on access roads. e Produce and place crushed surface course on access roads and along canals. R&M CONSULTANTS, INC. 18 Summary Level Supplement to Preliminary Design Report 10.3 Rough Order of Magnitude Estimated Cost for Battle Creek Project The Rough Order of Magnitude estimated cost for the Battle Creek Diversion Project is based on the 65 percent design developed using a digital terrain model from satellite imagery as the base for roads and the conveyance canals. The topography at the diversion site in the West Fork of Upper Battle Creek was further defined by ground survey methods. Geotechnical evaluation of the area is based on preliminary field evaluation of the geology and no definitive geotechnical program has been performed to date. Table 10-1 presents a summary of the ROM costs estimate. 10.3.1 Pre Construction A full geotechnical program including borings and further engineering geological evaluation is planned for the 2012 summer season and this will be done in concert with additional ground survey along road and canal routes and at structure sites to better define the topography. Final design documents will be completed to 100% for project license amendment process purposes and the cost estimate upgraded based on the definitive information available from the geotechnical, survey and final design results. Upon FERC approval of the application for amendment to the license for Bradley lake Hydroelectric Project, P-8221-AK, the construction documents would be prepared for solicitation of bids. 10.3.2 Construction Assuming FERC approval is received and the bid process can be completed for and award by about March 2013, construction could begin in 2013.
