May 26,2004,David Lockard of the Alaska Energy Authority/Rural Energy Group(AEA/REG)and Steve Stassel &John Dickerson of Alaska Energy and Engineering (AE&E)performed an initial site investigation to determine community energy related needs in Pelican.A second trip was made by David Lockard and John Dickerson on 4/12-13/05 to gather additional field data.A meeting was held at 7:00 PM on 4/12/05 with local officials and interested community residents to discuss potential energy infrastructure projects.Additionally,Bob Butera,P.E.of HDR,Inc.traveled to Pelican on 4/27-28/05 to assess the condition of the hydroelectric facilities. The City tank farm is in poor condition and in need of replacement.The existing tank farm site will be abandoned and a new site will be developed at the old school reserve (rock quarry)site to provide adequate area and set-backs for construction of the new tank farm.The fuel dock has adequate area and set- backs for gasoline dispensing and marine diesel transfer facilities. None of the existing tanks are suitable for reuse.Four new double wall bulk tanks located at the tank farm site,one double wall intermediate tank located at the new modular power plant,one double wall intermediate tank located at the freezer plant,and one single wall day tank located at the school will be provided to meet the projected fuel storage and dispensing requirements for the community.The City bulk tank farm will have a gross storage (tank shell)capacity of 40,000 gallons of #2 diesel fuel,20,000 gallons of #1 diesel fuel,and 12,000 gallons of gasoline for a combined gross storage capacity of 72,000 gallons.The intermediate tanks will have a gross storage (tank shell)capacity of 6,000 gallons each and the school day tank will have a capacity of 1,000 gallons.Fuel will be delivered to the bulk tank farm by barge.The intermediate tanks will have piped delivery.The school day tank will have truck delivery. The existing Pelican Seafoods cold storage power generation equipment is in poor condition and in need of replacement.A new prefabricated modular diesel power plant will be located near the freezer plant.The new power plant will include three new generators,programmable automatic paralleling switchgear,a fire suppression system,critical grade exhaust silencers,as well as all required engine coolant piping and ventilation equipment. Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering The existing turbine governor controls will be upgraded to allow the hydroelectric system to be integrated into the new diesel plant controls.This will include a new automated governor on the main turbine,new overhead fiber optic communication cable between the new diesel power plant and existing hydroelectric powerhouse as well as other miscellaneous integration and controls upgrades.These improvements will maximize utilization of available hydro generated power. Existing power distribution will be upgraded to improve service at the far eastern edge of the community.A new community feed step-up transformer will also be installed at the new power plant. The existing Pelican Creek hydroelectric facility was originally constructed in 1941. While it is presently operating,several portions are at the end of their useful life and in need of immediate replacement.Upgrades to the facility will include:a new intake structure,a new head box,a new steel pipe water conveyance system (replaces wooden flume),a new 36"diameter steel pipe penstock;trestle repairs, minor power house repairs;and a turbine evaluation. The proposed project schedule calls for design and permitting of the BFU and RPSU projects to occur simultaneously and to be completed by the winter of 2005/2006 and for construction in the summer of 2006 with the facilities fully functional by the fall of 2006.Design and permitting of the hydroelectric infrastructure upgrade project will be completed by the summer of 2006 for construction during winter of 2006/2007 with the facilities fully functional by the spring of 2007. The estimated cost of the BFU portion is $1,171,951 which equates to a unit cost of $13.79 per gallon based on a gross storage capacity of 85,000 gallons.This is within the Denali Commission benchmark cost range of $14.00 to $12.00 per gallon for 50,001 gallon to 100,000 gallon capacity tank farms. The estimated cost of the RPSU portion is $1,540,557 which equates to a unit cost of $2,170 per kW based on a total installed capacity of 710kW.This is withintheDenaliCommissionbenchmarkcostrangeof$2,400 to $1,900 per installed kW for 601kW to 800kW capacity power plants. The estimated cost of the hydroelectric upgrade portion is $1,291,514 which equates to a unit cost of $1,987 per kW based on a total installed capacity of650kW.This is within the Denali Commission benchmark cost range of $2,400 to $1,900 per installed kW for 601kW to 800kW capacity diesel power plants.In addition,the hydroelectric facility provided an average of approximately 2.5 million kWh of electricity for FY 2001 and 2004.Assuming a diesel generation efficiency of 12kWh/gallon of fuel,this represents an equivalent of 208,000 gallons of diesel fuel saved.Based on an estimated fuel price of $2.50/gallon,the annual operation savings are estimated to be approximately $520,000.The upgrade is necessary to ensure continued long term operation of the hydro facility.

INTRODUCTION This report has been prepared by Alaska Energy and Engineering,Inc.(AE&E) for the Alaska Energy Authority /Rural Energy Group (AEA/REG).The purpose of this study is to provide a concept design and construction cost estimate for the following potential energy infrastructure improvement projects for the City of Pelican: e Bulk Fuel Upgrade (BFU)-New bulk fuel storage and fuel handling facilities. e Rural Power System Upgrade (RPSU)-New modular power plant,new automated controls for existing hydroelectric powerhouse,and miscellaneous power distribution upgrades. e Hydroelectric Project -Hydroelectric facility water conveyance and powerhouse infrastructure upgrades. For the purpose of this study,the term "diesel fuel”refers to all fuel oil products used for space heating,electrical generation,and heavy equipment operation. Participants in the project include the City of Pelican (City),Pelican Seafoods, and Pelican Utilities.Pelican Seafoods and Pelican Utilities are subsidiaries of Kake Tribal Corporation. 1.1.Program Overview The Alaska Energy Authority (AEA),Rural Energy Group is pursuing grant funds to upgrade rural bulk fuel tank farms and electric power systems.All project components are dependent on available funding.Following is a brief outline of the program: e Most of the funds are federal and provided through the Denali Commission (DC).Other federal funding may be available from HUD (ICDBG)and the Environmental Protection Agency (EPA).Additional funds may be available from the State of Alaska,through the Department of Environmental Conservation and the Department of Education. e In order to receive grant funds,each community must demonstrate that the proposed facility will be sustainable by accepting a business plan.The business plan shall describe who will own the facility,and how it will be operated,maintained and replaced. e New energy projects are funded,designed,and constructed in three phases: Phase 1,Conceptual Design;Phase 2,Design Completion;and Phase 3, Construction. e During Phase 1,Conceptual Design,staff from AEA will visit a community, discuss the program,and work with residents and the local government to select sites for the new facilities. e At the completion of Phase 1 Conceptual Design,the community will be requested to review and approve the location,capacity,and basic configuration of the facilities as well as a draft business plan. e During Phase 2,Design Completion,the design for the new energy projects will be completed.An environmental assessment will be prepared and site control documented.A business plan will be prepared for signing. 1 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering e Each community will be requested to provide "in kind”contributions by providing the land for the new tank farm and free use of local heavy equipment.The grant funds pay for equipment fuel,maintenance,and repairs of equipment during construction. e Project may include local hire and construction trade training programs, subject to Denali Commission funding. e If construction funding is awarded then the business plan will be sent for signature and construction procurement will start. e Ineligible Projects:Funding is not available through AEA for buildings, propane facilities,fuel tank trucks or trailers,fuel to fill the tank farm, operation &maintenance costs,or residential tank upgrades.Loans for fuel tank trucks and trailers may be available through USDA. e Training Available:AEA has several training programs available for communities. 1.2 (Community Description Pelican is located on the northwest coast of Chichagof Island,on the east shore of Lisianski Inlet.It lies 70 miles west of Juneau,and 80 miles north of Sitka.It lies at approximately 57.96°North Latitude and 136.22°West Longitude.(Sec. 19,T045S,RO57E,Copper River Meridian.)The area encompasses 0.6 square miles of land and 0.1 square miles of water.Pelican has a maritime climate with cool summers and mild winters.Summer temperatures range from 51 to 62; winters 21 to 39.The highest recorded temperature is 84,and the lowest recorded temperature is minus 3F.Total precipitation averages 127 inches a year,with 120 inches of snow.The population was estimated at 118 residents in 2004.Pelican is a first class city and is not a federally recognized native village. Pelican is located in the Sitka Recording District and the Pelican City Schools District (PCSD). 1.3 Site Investigations An original site investigation was performed by David Lockard of the Alaska Energy Authority/Rural Energy Group (AEA/REG)along with Steve Stassel and John Dickerson of Alaska Energy &Engineering,Inc.(AE&E)on May 26,2004. The purpose of our site visit was to observe the existing energy related infrastructure and to gather reconnaissance level information to 'identify community energy related needs. A second site investigation was performed on April 12-13,2005 by David Lockard and John Dickerson.The purpose of the second site visit was to meet with local residents to discuss the scope of potential energy infrastructure projects and to locate potential tank farm and power plant sites within the community.Additional field data was gathered on existing community power generation and distribution as well as existing fuel handling facilities.At 7:00 p.m.on April 12 a meeting was held with local officials and interested community residents to discuss potential energy infrastructure projects. Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering On April 27-28,2005 hydroelectric generation specialist Bob Butera,P.E.of HDR,Inc.traveled to Pelican.The purpose of his trip was to assess the general condition of the dam,intake,flume,penstock and powerhouse.This included wood coring of the flume and penstock trestle timbers.A memorandum containing his findings and analysis is included in Appendix E of this report. In addition to the field investigations,available information was obtained and analyzed from the following sources: e State of Alaska Department of Community and Regional Affairs (DCRA)Bulk Fuel Community Database e Pelican Power Alternatives Feasibility Study,USKH,1983 e Pelican Utilities Study,HDR Alaska,August 1996 e Pelican Creek Hydroelectric Intake and Dam Upgrade Design,Polar Consult Alaska,Inc.,March,1991 e Pelican Seafoods Power Plant Penstock Replacement Project,Polar Consult Alaska,Inc.,July,2001 Pelican Waterfront Plan,PND Inc.Consulting Engineers,August,2004 Pelican ,survey plats Pelican Power Cost Equalization (PCE)fuel use data,1995-1996 Corps of Engineers wetlands and flood information Other relevant data. Additional information and input was obtained from the following individuals: e Patricia Phillips,Mayor,City of Pelican 735-2204 e Allen Stewart,Public Works Director,City of Pelican 735-2204 e Betty Bean,Clerk/Treasurer,City of Pelican 735-2204 e Tom Whitmarsh,Pelican Utility Co.735-2202 e Paula Burgner,Pelican Seafoods 735-2202 e Bob Butera,P.E.,HDR Alaska 644-2000 e Deenie Wilson,Petro Marine Services,Anchorage 562-5000 e Lee Hanson,Hanson Maritime,Sitka 747-1055 e Alaska Marine Lines,Seattle 206-764-8346 e Northland Services,Seattle 1-800-426-3113 e Marcy Johnson,Channel Construction,Juneau 789-0200 e Doug Trucano,Trucano Construction 586-2444 1.4 Code Analysis Prior work performed by the State of Alaska Division of Energy (DOE)included a code evaluation of existing facilities and preparation of a database summarizing results.The existing facilities were reviewed and information in the database verified.The following is a summary of existing facility deficiencies observed: e Improper Secondary Containment (Diking) Tanks (bottoms)are not within a proper liquid tight secondary containment system of adequate capacity as required by the Fire Code and EPA regulations. Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering e No Emergency Vents -None of the tanks have emergency vents,in violation of the Fire Code. e No Security Fence -Some tanks are currently accessible to the general public with no security fencing.This presents a hazard to the community as well as increasing the chance of a spill or fire due to vandalism and theft. e Improper Piping and Valves -Existing piping systems consist of steel piping with a combination of welded and threaded joints.The threaded joints are particularly prone to leaking.Some valves are made of bronze,in violation of the Fire Code. e Gravity Dispensing -Code requires that all fuel dispensing be by pump. e Above-Ground Dispensing Tank Capacity -State Fire Marshall requirements stipulate that the maximum size of an above ground dispensing tank is 12,000 gallons. e Dispensing From Above-Ground Tanks Without Protective Systems -State Fire Marshall requirements stipulate protective devices and piping systems to prevent a gravity discharge of fuel in the event of a failure of the dispenser or piping.No protective devices are installed. e Improper Site Location -The existing bulk tanks do not meet Fire Code minimum separation distance requirements from adjacent public ways and property lines for unprotected tanks. e Improper Foundation -Horizontal tank resting directly on ground with no foundation. The combination of deficiencies poses a significant threat to public safety and the environment.A major project is required to construct a new code and regulation compliant tank farm to meet the long-term needs of Pelican. The concept design for the new facility has been prepared to meet current code and regulatory requirements which include: e The 2003 Edition of the International Fire Code,including State of Alaska Amendments e The 2002 Edition of the National Electrical Code e 40 CFR,Part 112.1-12,U.S.Environmental Protection Agency Spill Prevention Requirements e 33 CFR,Part 154.30 &154.1030,U.S.Coast Guard Spill Prevention Requirements The design also incorporates appropriate industry standards such as National Fire Protection Association (NFPA)and American Petroleum Institute (API)as well as proven methods and materials that have been used successfully on other rural bulk fuel facilities in similar locations and climates. Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering 2.0 EXISTING FUEL STORAGE FACILITIES -FUNCTION AND CAPACITY The tank farm number below corresponds to the number assigned in the DOE database.The facility was evaluated to determine specific needs and deficiencies.Tanks were visually examined to determine suitability for re-use. The following paragraphs summarize findings for the tank farm: Pelican Seafoods -Tank Farm (#1).The Pelican Seafoods bulk fuel storage facility consists of six in-service vertical steel bulk storage/dispensing tanks,a three product marine header,a three product marine dispenser,a #1/#2 diesel bulk transfer (truck loading)hose connection,and multiple above ground distribution and transfer pipelines.The tank farm is located on the hillside above and to the east of the fuel dock.Tank farm access is by a covered wooden stairway from the main city boardwalk.The facility provides storage for virtually all the #2 diesel,#1 diesel,and unleaded gasoline received by the community. The fuel is used to generate power when required to augment the hydro electric plant,to provide for Pelican Seafoods in-house operations,as well as to dispense fuel to the fishing fleet and general public.All dispensing and bulk transfers are by gravity. The total gross shell capacity of the six in-service bulk storage/dispensing tanks is approximately 60,000 gallons of #2 diesel,40,000 gallons of #1 diesel and 20,000 gallons of unleaded gasoline.The tanks are approximately 50 years old but appear to be well maintained,with good paint except for some loose paint and rust along the bottom seams.The condition of the tank bottoms is suspect due to the age of the tanks but no thickness testing has been performed on them to date.The tanks are equipped with normal vents and manways.They have 3" flanged bottom connections with flanged steel plug valves and 1"threaded steel PRV jumpers for pipeline pressure relief.The manifold piping appears to be in good condition and is well supported but there were no flexes between tank connections.The tanks are supported on concrete bases within a 98'long x 20' wide x 2'-8”"high heavy timber dike.In the late 1990's the dike floor was covered and sealed to the base of the tanks with an application of "Fusion Crete",a lightweight cement material.A dike membrane liner was installed on the vertical dike walls and sealed to the dike floor with metal flat bar,sealant and stud anchors.The dike appears to be liquid tight but does not provide secondary containment for the tank bottoms. There are three each 3"diameter HDPE coated welded steel barge fill/distribution pipelines that run from the marine header to the tank farm, supported above grade on the dock,boardwalk and tank farm access stair structures.The HDPE coating appears to be in good condition.All elbows and pipe joints appear to be well sealed with heat shrink tape. The three product marine header is located on the end of the fuel dock.Each barge connection has a 3”quick disconnect hose coupling,a 3"flanged steel check valve,and a 3"flanged steel plug valve.There is a single aluminum drip pan that serves all three marine header fill connections and appears to have adequate capacity to meet the 84 gallon containment requirement.The marine 5 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering dispensers are also located on the face of the fuel dock and are gravity fed with 2"welded steel branch pipelines off of the main 3"barge fill/distribution pipelines. There is a bulk transfer hose and meter located along the main boardwalk near the fuel dock that allows for bulk loading #1 or #2 diesel into drums and portable tanks for distribution within the community.A 2"bulk transfer pump with meter located in a small enclosure on the fuel dock is used for transferring #1 or #2 diesel to 500 gallon residential style day tanks at several buildings as well as to a 6,000 gallon day tank at the power plant.These various tanks are supplied by a network of welded and threaded steel pipelines from 1"to 2"in diameter routed along the main boardwalk and building stairways. Pelican Seafoods -Power Plant Day Tank (#2).There is a 6,300 gallon single wall welded steel diesel storage tank located behind the seafood plant.This tank is pipeline filled from the transfer pump located on the fuel dock.It feeds the generators through an insulated,heat-traced 1-1/4"welded steel pipeline. For winter operations,#1 and #2 diesel fuel are mixed in this tank for winter blend fuel.This tank also provides fuel for space heating of the store and bunk house through copper fuel oil supply and return lines.The tank is supported on heavy timbers and is contained within an old cement building foundation.There is no dike liner,emergency vent or security fencing.The tank is in poor to fair condition with some blistering and peeling paint.A fuel spill of between 300 and 750 gallons (approximately 100 gallons unrecovered)occurred at this tank in March,2004.The spill was caused by open valves in the gravity feed supply line. Pelican School -Fuel Tank (#3).A 2,000 gallon single wall welded steel diesel storage tank is located adjacent to the covered play area and across the boardwalk from the elementary school.This tank is truck filled.It provides fuel for space heating of the school buildings through buried copper fuel oil supply and return lines.The tank rests directly on the ground,with no foundation, saddles or cribbing.There is no secondary containment,emergency vent or security fencing.The tank is in very poor condition with poor paint and severe surface rust. 2.1.Existing Equipment Suitable for Reuse All of the tanks,associated piping systems and equipment are in marginal condition and would not be cost effective to renovate. 2.2 Demolition of Existing Tanks The scope of this project will also include removal from service of all existing tanks.All abandoned tanks will be drained of product,the piping will be removed,and the tank connections will be plugged or blind flanged in accordance with current AEA standards and procedures. Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering 3.0 CURRENT FUEL CONSUMPTION Pelican Seafoods imports virtually all the fuel used by the community of Pelican. Therefore fuel purchase records were obtained from Pelican Seafoods for 2002 and 2003 in order to determine community fuel use quantities.The following table summarizes average consumption and existing storage capacity.All capacities are in gallons.Net capacity is calculated as 90%of the tank gross (shell)capacity. CURRENT CONSUMPTION VERSUS EXISTING COMMUNITY CAPACITY Product Average Existing Existing Annual Net Gross Use (1)Capacity Capacity #2 Diesel Fuel 128,000 54,000 60,000 #1 Diesel Fuel 76,000 36,000 40,000 Unleaded Gasoline 28,000 18,000 20,000 Existing Total 232,000 108,000 120,000 (1)Two year average for 2002 and 2003 3.1.Planned Infrastructure Improvements It is important to evaluate the impact of planned near-term infrastructure improvement projects on existing utility systems.New construction and other community improvements can adversely impact the adequacy of existing utilities. The City of Pelican has recently taken ownership of the water utility and a new water plant and distribution system with freeze protection is currently being designed by HDR Alaska,Inc.Due to recent declines in commercial fishing the local population is in decline.so there is no expected near term residential construction.There are no other known construction projects that are likely to affect community fuel consumption.Following is the estimated impact these factors on future fuel consumption: e New water utility heating -7,000 gallon annual increase in #2 diesel use. e New seasonal tourists and charter fishing operations resulting in an increase in gasoline consumption -allow 4,000 gallon increase in city gasoline sales during summer months. 3.2.Alternative Energy/Efficiency Improvements An analysis of a proposed hydroelectric generation upgrade project is included in Section 5.3.The proposed hydroelectric upgrades are primarily intended to extend the life and reliability of the existing facility and are not expected to have much impact on annual fuel use in Pelican. Pelican Energy Infrastructure Projects September 13,2005 Concept Desiqn Report Alaska Energy and Engineering In section 5.2 there is a description of a proposed upgrade to the hydroelectric generator controls.The primary purpose of the upgrade is to improve the coordination between the new diesel plant and the existing hydro plant and to automate some of the functions.The net result of the improved coordination should be better utilization of available hydro power and a resultant reduction in diesel consumption. Diesel generation will still be required when hydro power is not available and also to meet peak demands during periods of reduced hydro output.Careful sizing and selection of new diesel-electric generators in conjunction with the installation of fully automatic paralleling switchgear and distribution improvements will result in optimum community power generation fuel efficiency. There are no identified facilities,such as a school or public building,within a practical distance of the proposed power plant location that could benefit from recovered engine heat.In addition,since the run time of the diesel generators is minimal (approximately 1,500 hours per year)it is doubtful that heat recovery could ever be cost effective.Based on this combination of factors there are no plans to install heat recovery equipment in the new power plant module. The Alaska Energy Authority/Alaska Industrial Development and Export Authority published a draft Rural Alaska Energy Plan dated December 31,2002 as a follow-up report to the previously released Screening Report of Alaska Rural Energy Plan dated April 2001.The Screening Report evaluated a dozen alternative energy technologies other than diesel engine heat recovery.Only wind energy was identified as alternative energy technology warranting further evaluation in the draft Rural Alaska Energy Plan.According to the Wind Energy Resource Atlas of the United States the community of Pelican is located within a class 3 wind regime and is not a viable candidate for a wind energy program using currently available technologies. An energy audit was performed and a series of energy efficiency measures were recommended by the Alaska Energy Authority in the spring of 2001.These suggested improvements included replacement of existing lighting fixtures,the -- installation of storm windows,additional attic and floor insulation,new door weather stripping,replacement of electric water heaters with oil-fired units or demand electric heaters,replacement of electric baseboard heat with Monitor- style heaters,as well as other suggested energy efficiency improvements in community buildings.A report is available from AEA on these suggested measures,including an analysis of the predicted savings. There are no other known practical energy sources,such as solid fuel or natural gas,currently available at Pelican.At this time,it appears that supplemental hydroelectric generation and possibly additional end-use conservation are the only viable energy reduction technologies available for Pelican. Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering 3.3.Tank Capacity Requirements Pelican is located on a year round ice-free port with a deep water dock capable of receiving ocean-going fuel barges.Fuel barges are scheduled to be in the area at least every two to three weeks.In communities that have limited barge access it is standard to size the bulk fuel storage facility for a thirteen month supply of fuel.In this case the community has averaged approximately fourteen barge deliveries per year,spaced from 2 weeks to two months apart.Therefore a different approach was taken in determining required tank capacity.The local fuel barge delivery service offers a $0.05 discount on fuel when the total quantity of all products delivered per trip exceeds 20,000 gallons.Based on this delivery schedule and price structure,the facility has been sized to hold an approximate two months supply of each product and to have at least 20,000 gallons of total available capacity per scheduled delivery with an adequate reserve margin. During peak fuel sales periods,such as commercial fish openings,additional deliveries can be scheduled as required.The following table compares the anticipated future annual and 2 month use for each product to the proposed net useable tank capacity for the new facility: CONSUMPTION VERSUS CAPACITY Product |Est.Est.Proposed |%of %of |Proposed Future Peak 2 Net Est.2 |Est.Gross Annual Month Capacity Month |Annu |Capacity Use in Use in in Gallons |Use al in Gallons Gallons(1)|Gallons |(2)Use Gasoline 32,000 8,000 10,800 135%|25%12,000 #1 Diesel 76,000 |15,000 18,000 120%|24%20,000 #2 Diesel 137,000 |30,000 46,800 120%|26%|53,000 (3) Prolect 245,000 |53,000 75,600 |158%|34%|85,000 (1)Current average plus near-term future increases.

Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering 4.1 Tank Farm Site The Tank Farm site shown in Appendix A,Site Plan Sheet M3 was selected as the preferred site for a bulk fuel storage facility by the Pelican City Council.This site is entirely contained within Block 8,US Survey No.2861.It is a City-owned 200"x 200°(40,000 square feet)parcel.It was originally designated as school reserve.property but is no longer required for that purpose since a different location was selected when the school was constructed.A portion of this site has been used in the past as a rock quarry.This has resulted in a relatively level area measuring approximately 60'x100'surrounded by uneven terrain with bedrock outcroppings and thick brush.Aerial photography generated contours have been used for a conceptual layout of a facility at this site.From on-site measurements and photos it appears that the existing level bench provides adequate area for placing the tanks.A detailed topographic/geotechnical survey will need to be performed at the site to establish property corners,elevation bench marks,provide detailed surface contour elevation data and to establish the depth of bedrock by probe for final design.These tasks will need to be performed early in the design phase. Site access is by Coho Way,an existing gravel road that also provides access to the community solid waste landfill.Access along Coho Way can be difficult at times during the winter season due to slippery conditions and the steep grade as the road climbs the hill from the boardwalk. The tank farm site is well above the level of Pelican Inlet and there is no threat of flooding there.According to the Corps of Engineers,Alaska Communities Flood Hazard Data,June 2000,there is no flood hazard in Pelican. 4.2 Power Plant Site The Power Plant site shown in Appendix A,Site Plan Sheet M3 was selected as the preferred site for a new modular power plant by the Pelican City Council. This site is owned by Pelican Seafoods,Inc.and is contained entirely within the property defined by Lot 2,Pelican Seafoods Subdivision.The proposed power plant site is located approximately 40'north of the existing Pelican Seafoods diesel-electric power plant building and approximately 50'down-slope from the existing 6,000 gallon power plant day tank.The area proposed for the new modular power plant installation appears to consist of mostly undisturbed soil with heavy brush cover and shallow bedrock.The southern edge of the site slopes steeply down to the existing power plant while the majority of the site slopes toward a short,rocky bluff overlooking Lisianski Inlet,approximately 60'to the west.Due to the long history of continual industrial use and at least one reported oil spill from the existing day tank,a below surface geotechnical and environmental assessment of this site should be scheduled early in the design phase.The results of the investigation will determine the site work required prior to beginning construction on this site and will determine the appropriate foundation design for the modular power plant.Site access is by Salmon Way, an existing gravel road that also provides access to residences along the coast to the north of the Seafood Plant. 10 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering Aerial photography generated contours and on site observations indicate that the top of the rocky bluff is approximately 15'above the high tide mark and the proposed Power Plant site is approximately 12'in elevation above that point.A detailed topographic survey will need to be performed at the site to establish property corners,elevation bench marks and to provide detailed surface contour elevation data.These tasks will need to be performed early in the design phase. 4.3.Truck Loading Site A truck loading area shown in Appendix A,Site Plan Sheet M3 will be constructed along Salmon Way (boardwalk)in the area of the existing truck fill hose stand near the intersection of the fuel dock and boardwalk.The footprint of this facility will be kept to a minimum to prevent any intrusion into the boardwalk.The IFC requires that the hose stand be a minimum of 15'from combustible materials,buildings and property lines which are or can be built upon.A detailed as-built survey of this area will need to be performed prior to final design to establish the exact location of the boardwalk,the road right-of- way,and all existing structures in order to come up with a placement that will meet all code required set backs and separations. 4.4 Fuel Dock The marine header,retail gasoline dispenser,#1/#2 diesel marine fueling station, and portions of the barge fill/distribution pipelines will be located beside and under the existing fuel dock,as shown in Appendix A,Site Plan Sheet M3. 4.5 Hydroelectric Upgrade Project Site The entire hydroelectric generation facility,including dam,flume,penstock and powerhouse is encompassed by an approximately 200'wide x 1,200'long utility easement that runs just north of Pelican Creek near the southern end of town,as shown in Appendix A,Overall Community Site Plan Sheet M1.The hydroelectric utility easement lies entirely within the Pelican City corporate boundary. 4.6 School Site The Pelican School facility is located within Block 14,U.S.Survey 2861,as shown in Appendix A,Overall Community Site Plan Sheet M1.The property is reported to belong to the City of Pelican. 4.7 Site Control A Certificate to Plat was issued by First American Title of Alaska effective July 5, 2005.Acopy of the Certificate to Plat is included in Appendix C. The proposed new tank farm site is located within Block 8,U.S.Survey 2861. This property was originally designated as a school reserve and is vested in the City of Pelican. The proposed new power plant site is located within Lot 1,U.S.Survey 2819. This property is vested in the Kake Tribal Corporation.The property will need to 11 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering be subdivided to provide a small parcel for the power plant,and a long term lease or deed secured to provide site control to the City. The truck loading facility is located within a section of the Salmon Way right of way within U.S.Survey 2861 and owned by the City of Pelican.An easement will be delineated for installation of public utilities including fuel pipelines and fuel handling facilities. The barge header,gasoline dispenser,and diesel bulk transfer facility are located on the southern end of the fuel dock.The fill/distribution pipelines from the barge header to the tank farm site will be routed beside the dock,under the boardwalk and then buried within the Coho Way right-of-way.The dock is located on Lot 3,Block 17 Alaska Tidelands Survey No.12,which is vested in Kake Tribal Corporation.Coho Way is also located within U.S.Survey 2861, Pelican Townsite and is owned by the City of Pelican.An easement will be delineated for installation of public utilities including fuel pipelines and fuel handling facilities. The existing hydroelectric facility is located within utility easement FSRP 101771 as defined in Alaska Power Project No.10198 (AA-57996)and is vested in the United States of America. 5.0 PROPOSED FACILITY DESCRIPTION The following proposed facility description is separated into three sections: Section 5.1,"Bulk Fuel Upgrade",describes the proposed new community fuel storage and handling facility;Section 5.2,"Power System Upgrade",describes the proposed new diesel-electric power plant as well as upgrades to the existing electrical distribution system;and Section 5.3,"Hydroelectric Project",describes the proposed Pelican Creek hydroelectric upgrades. The availability of reliable year-round power generation and access to fuel are basic requirements for the community of Pelican.The Pelican Creek hydroelectric facility provides the major portion of community power generation and has reduced energy costs significantly over its lifetime.However,it cannot be relied upon as the sole source of electrical generation due to both predicted and possible unpredicted water flow restrictions.Permitting,design and construction logistics are compatible for the proposed Bulk Fuel Upgrade (BFU) and Rural Power System Upgrade (RPSU)projects.However,the time-line for permitting and design for the hydroelectric upgrade project is likely to take longer.In addition,the power generation work will need to be separated to limit interruptions of power service in the community.Therefore,it is assumed that the BFU and RPSU projects will be constructed simultaneously and the Hydroelectric project will be constructed separately as a stand-alone project.All cost estimating and construction scheduling will be based on the separation of BFU/RPSU work from the Hydroelectric Project work. 12 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering 5.1.Bulk Fuel Upgrade The BFU project will consist of replacing the existing tank farm,pipelines and associated fuel handling equipment in their entirety.In addition,new intermediate tanks will be installed at the new City modular power plant and at the existing Pelican Seafoods powerhouse.A new day tank will also be installed at the school. The proposed new City tank farm will be located on the hillside above town on Coho Way and will provide storage for virtually all of the diesel fuel and gasoline received by the community of Pelican.The new tank farm will include one 20,000 gallon bulk storage tank for #1 diesel,two each 20,000 gallon bulk storage tanks for #2 diesel,and one 12,000 gallon gasoline dispensing tank.A security fence will enclose the tanks.See Appendix A,Tank Farm Site Plan Sheet M4. The fuel dock renovation will include new marine fueling stations for #1 and #2 diesel fuel as well as an unleaded gasoline dispenser.The diesel fueling stations and gasoline dispenser will have separate custody transfer meters,hose reels,and nozzles for each product.The installation will also include a new three product marine header as well as fill/distribution pipelines for #1 diesel,#2 diesel, and gasoline.The pipelines will route beside the dock,then cross under the boardwalk and finally below grade within the Coho Way right-of-way up to the tank farm site. A truck loading area will be constructed along the boardwalk near the intersection with the fuel dock.This facility will be used only for filling the local fuel delivery truck and other portable tanks with #2 or #1 diesel.A custody transfer meter and hose stand will be installed within a small security enclosure. 5.1.1 Secondary Containment The International Fire Code and E.P.A.regulations require fuel tanks to have secondary containment.The regulations include provisions that allow for secondary containment utilizing double wall tanks with redundant overfill protection equipment.Secondary containment requirements for all bulk fuel storage for this project will be met by using double wall tanks equipped with the required overfill protection devices.The gasoline dispensing tank will also be required to be two hour fire-rated due to the close proximity to property lines. Truck loading facilities are required to have secondary containment capable of holding the contents of the largest tanker truck to be filled.The proposed truck loading facility in Pelican will be used for filling the local 300 gallon fuel delivery truck as well as other portable tanks.Secondary containment requirements for this facility will be met by utilizing a drive-in/drive-out portable containment berm placed on the boardwalk during fuel transfers. 5.1.2 Tanks A total of three bulk storage tanks,two intermediate tanks and one day tank will be required.The three bulk storage tanks are 20,000 gallon gross shell capacity 13 Pelican Energy Infrastructure Projects September 13,2005 Concept Desiqn Report Alaska Energy and Engineering tanks for diesel storage,one for #1 diesel and two each for #2 diesel.The two intermediate tanks will have a gross shell capacity of 6,000 gallons each and will be used for on-site storage of #2 diesel for diesel-electric generation.The day tank will have a gross shell capacity of 1,000 gallons and will be used for on-site storage of #2 diesel for school space heating.The bulk storage and intermediate tanks will be shop built double wall horizontal welded steel tanks built and labeled in accordance with UL 142 and equipped with overfill protection. A single gasoline dispensing tank with a gross shell capacity 12,000 gallons will be required.This tank will be a two hour fire rated double wall horizontal welded steel tank built and labeled in accordance with UL 2085.It will also be equipped with overfill protection. All tanks will be equipped with level gauges,pressure/vacuum whistle vents, emergency vents,manholes and water draws.The tanks will have steel skid foundations which will be placed on concrete footings sized to limit soil bearing pressure to 1,500 pounds per square foot.The tanks will be coated with an inorganic zinc primer and two layers of epoxy for corrosion protection. 5.1.3 Piping/Valves/Pumps/Accessories All above-grade piping will be schedule 80 steel with a high density polyethylene coating.All below-grade piping will be schedule 80 steel with a high density polyethylene coating and cathodic protection.Above-grade piping will be installed on concrete pads or supported from tanks or structures and secured with steel pipe straps or hangers.All fuel dock piping will be secured with stainless steel strut and pipe straps or hangers.All piping joints will be welded or flanged except for connections to pumps and specialty valves which may be threaded.Sufficient flanged joints will be provided to allow service of pumps and other devices.All connections to pumps and tanks will be made with stainless steel flexible connectors.Each isolated section of piping will be provided with pressure relieving devices to account for thermal expansion of product caused by temperature fluctuations.Provisions for movement of the piping caused by thermal expansion and contraction will also be included.All valves will be steel body industrial grade valves intended for use with fuels. Three 3”diameter fill pipelines will be routed from a new marine header approximately 750°feet to the tank farm.A drip pan will be provided at the termination of the fill pipelines (marine header). A truck loading facility will be provided to allow the local tanker truck and portable tanks to be filled with #1 or #2 diesel from the City bulk storage tanks.The truck loading equipment will include submersible pumps on the #1 and #2 diesel bulk tanks,a filter,a custody transfer meter,a section of 1"hose,a 1”bulk transfer nozzle,and a static grounding line. A marine fueling facility will be provided on the fuel dock to allow bulk transfers of #1 and #2 diesel to marine vessels.The marine fueling equipment will include:a submersible pumps on the #1 and #2 diesel bulk tanks;two each actuated ball valves for submersible pump anti-siphon protection;two each filters;two each 14 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering é custody transfer meters;a manual rewind 3/4"hose reel and nozzle for #1 diesel;and a manual rewind 1-1/4"hose reel and nozzle for #2 diesel. A gasoline dispenser will be provided on the fuel dock to allow dispensing of gasoline to marine vessels as well as into vehicles and small containers on the dock.Gasoline dispensing equipment will include:a submersible pump on the gasoline dispensing tank;an actuated ball valve for submersible pump anti- siphon protection;a filter;a custody transfer meter;and a manual rewind 3/4” hose reel and nozzle. 5.1.4 Security The tank farm will be enclosed by a 6'tall chain link fence with a 1'high barbed wire top.A pair of 3'wide access gates will be provided into the fenced enclosure.All valves will be provided with lockable handles to prevent theft and vandalism.Pump controls will be installed within fenced security areas or buildings.Area lighting will be provided at the tank farm for security and spill detection and to enhance winter operation. 5.2 Power System Upgrade The RPSU project will consist of:1)installing a new modular diesel power plant; 2)installing new instrumentation and controls in the existing hydro powerhouse; 3)installing an overhead fiber optic communication cable between the new modular power plant and existing hydro powerhouse for remote monitoring and control of the hydroelectric generators and;4)a few minor distribution upgrades within the community. 5.2.1 Existing Cold Storage Power Plant Much of the existing generation and distribution equipment at this facility was originally installed in the 1960's and is in immediate need of upgrade or replacement.The facility consists of five antiquated Caterpillar generators (four operational,one out of service)located in the engine/refrigeration room at the Pelican Seafoods cold storage plant as well as switchgear and a two-way transformer bank distribution connection.In addition to providing power for all of the freezer plant's electric motor driven refrigeration equipment,these units are used to supplement community power generation during periods of low hydroelectric production.The gensets range from 100kW to 400kW,with a combined nominal capacity of 1,360kKW (approximately 1,000kW currently usable).All units run at 1,800RPM and power generation is at 480V 3-phase. Switchgear is manually operated and includes a section for each generator and a distribution section.The system allows the diesel generators to be run in parallel with the hydroelectric turbines as required.Power from the gensets is routed to a step up transformer bank adjacent to the seafood plant for conversion to 2,400/4,160V 3-phase for distribution.When the freezer plant generators are not running,480V 3-phase power is fed back to the freezer plant station service through the same transformer bank. 15 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering 5.2.2 Community Power Demand PCE data is only available through 1999,the last year that Pelican participated in the PCE program.Pelican Utility Company operator logs were also obtained for 2001 and 2004.This combined data is included in Appendix D. According to the available data,peak demand in Pelican fell from approximately 1,000kW in 1995 to approximately 400kW in 2004,and average annual demand fell from 400kKW to 220kW over the same period.These levels represent the sum of Pelican Seafoods fish plant loads and community loads with peaks occurring during the summer fishing season.The fall in electrical demand was largely due to the decline of commercial fish processing in Pelican,a result of major changes in both commercial fish management and world markets.Due to these difficult financial conditions,major buying and freezing operations at the fish plant were closed after the 2001 season.Since that time the plant has been used only for fresh-pack operations,which requires ice making and cold storage but with much less refrigeration capacity requirements than in the past due to the limited amount of blast freezing required.The highest recorded "summer fishing season"load in the 2004 operator logs was 390kW on July 27.The highest recorded "winter season"load in the 2004 operator log was 340kW on February 14.It is anticipated that community loads will remain constant or grow only slightly over the next ten years. If ownership of Pelican Utilities is transferred to the City and/or if Pelican Seafoods is sold to a new party there may be no long term obligation to continue maintaining and operating the existing cold storage power plant for community power generation.The seafood plant is currently for sale and based on information from Pelican Seafood management,potential buyers of the plant have expressed the preference of purchasing power from the electric utility rather than to continuing to operate this antiquated equipment.The new modular power plant should have adequate capacity to meet current peak community loads in case of the temporary total loss of hydroelectric generation. This would not include any future full scale blast freezing operations at the fish plant since these have not occurred since 2001 and there is no assurance that this type of operation will occur again in the future.If the need to operate a large scale blast freezing operation should arise in the future,the seafood plant could install new generation equipment or diesel powered refrigeration compressors to meet additional demand at that time.Other options,such as solid state soft-start controls and smaller,more efficient rotary or screw type _refrigeration compressors could also be investigated at that time. The hydroelectric facility provided approximately 85%of the power generation in Pelican in 2004 and total combined diesel generator run time was approximately 1500 hours.There are typically one to two months during the winter season of diminished or non-existent hydroelectric power supply due to low water in the reservoir.Peak demand during this period is likely to be between 300kW and 350kW,with average loads between 200kKW and 250kW.Power recording equipment was installed in the hydroelectric powerhouse and cold storage diesel 16 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering plant on August 8,2005 to monitor the electrical demand.The load data will be used to size generation equipment for the new power plant. 5.2.3.New Modular Power Plant The proposed new power plant will include three new generators,programmable automatic paralleling switchgear,remote radiators with variable speed control,a fire suppression system,critical grade exhaust silencers and an automatic fill day tank as well as all required engine coolant piping and ventilation equipment.It will come pre-assembled in a 15'-8"W x 41'-8"L modular skid-mounted building. The engine cooling system will consist of 3"copper coolant supply and discharge piping manifolds and dual remote radiators with variable speed control.A new automatic fill 100 gallon fuel oil day tank will be installed.It will be equipped with redundant overfill protection and alarm systems,a hand priming pump,and a totalizing meter.Welded steel fuel piping will be installed within the plant. 5.2.4 Generation Equipment Because the diesel power generation will only operate a small percentage of the year,it is acceptable to parallel two units to meet the peak load.Ideally the new power plant should have three generators sized so that any two will have sufficient combined capacity to meet normal peak community loads.One of the generators should be smaller than the other two to allow efficient operation when a small amount of diesel power is required to meet peaks during wintertime low water flow periods.It is proposed that a pair of 260kW prime rated generators and one 190kW prime rated generator be installed,for a total installed capacity of 710kW. Automatic paralleling switchgear in the diesel plant,new data acquisition instrumentation and governor controls at the hydro powerhouse,and an overhead fiber optic communication cable between the hydro powerhouse and the new modular power plant will allow any combination of generators to be operated in parallel as required to meet the demand and provide the most efficient generation. The new switchgear will have a total of 4 sections -one for each diesel generator and one for master control and distribution.The switchgear will be fully automatic with paralleling capability and will utilize a programmable logic controller (PLC)to automatically match the running generator(s)to the community load.Optimum fuel efficiency will be achieved by matching the generator to the load.This style of switchgear has been used successfully on several recent Energy Authority projects.The distribution section will include two feeders each with separate circuit breakers and metering -one for power plant station service and one for the community distribution.A totalizing meter will also be installed to record the total power generated. 5.2.5 Hydroelectric Controls Upgrades The existing turbine governor controls will be upgraded to allow the hydroelectric system to be integrated into the new diesel plant controls.This will allow the new 17 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering diesel generators and the existing hydro generator to be used in the most efficient manner to get maximum benefit from the available hydro resources without jeopardizing the electrical power supply.Upgrades to the governor controls will consist of the following: Installation of a new remote terminal unit (RTU)inside the hydro plant powerhouse.The new RTU will operate as remote input/output (I/O)for the diesel plant PLC.The RTU will be provided with provisions for local control in the event the main PLC is down or the communication link between the diesel plant and the hydro plant is lost.In addition to generator monitoring and governor control the RTU will also monitor a new level indicator on the surge tank,hydro generator breaker position,and other inputs that may be required. Installation of a new power meter on the existing hydro generator in the existing switchgear.The new power meter will monitor load parameters on the hydro generator such as three-phase amps,three-phase voltage,watts, vars,and power factor,and provide that information to the RTU. Modification of the existing switchgear.The existing switchgear will be modified as required to provide remote open and close of both existing generator breakers from the new RTU. Installation of fiber optic cable.Communication between the diesel plant PLC and the hydro plant RTU will be provided by a new single-mode fiber optic link.This will be accomplished by installing a "Figure 8”6-pair fiber optic cable on the existing overhead distribution system poles.Ethernet switches with fiber optic ports will be provided at both the diesel and hydro plants. Installation of a new continuous level indicator on the surge tank.To maximize utilization of the hydro generator,knowledge of the water level in the surge tank is required.The new level indicator will be a pressure transducer suspended from the top of the surge tank to a point near the bottom.The level indicator will be weighted to keep it in place and will be provided with adequate length of cable to reach from the transmitter to the new RTU. Replacement of the hydro turbine governor.The existing governor controller is a mechanical governor,Woodward model UG-8 8520-383,UG-HT size 2. The existing governor controller is not upgradeable so the existing governor will be replaced with a new electronic governor control system. Modification of the existing 100 kW induction generator turbine valve. Modifications will be made to incorporate control of the existing induction generator in the overall generation system. 5.2.6 Distribution Upgrades Proposed community power distribution upgrades include: New community step up transformer bank. New secondary service to seafood plant for base operations. 18 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering e Existing power feeder from the seafood plant powerhouse to the distribution system to remain. e Replacement of the final four power poles at the east end of town with regulation height poles. e Installation of new 3 phase primary conductors on the new poles. e Installation of a new transformer and secondary service to customers affected by 3 phase upgrade (approximately four services). e Extension of distribution (buried)to the new tank farm site. e Coordinate with VSW provide secondary service to new water plant. 5.3.Hydroelectric Project The primary electric power source for Pelican is a hydroelectric generation plant. This facility was originally constructed in 1941.Some portions of the system are still original construction while others have been replaced.The facility has a minimal storage dam and operates essentially as a run of the river system.It consists of the following components: e Low height rock-filled timber crib dam that was rebuilt between 1996 and 2002 and is in good condition. e Concrete intake structure that is in marginal condition. e Timber construction open flume 727'in length that is in poor condition.The flume is installed on timber trestles.The upper portion of the trestle is in poor condition but the lower portion is in fair condition. e Timber surge tank with screens in marginal condition. e Wood stave penstock 330'in length that is in poor condition. e Powerhouse building that was rebuilt in 1982 and is in good condition. e Apair of turbine generators of 550kW and 100kW capacity. All available hydroelectric facility infrastructure data and information gathered on all site visits was forwarded to hydroelectric generation specialist Bob Butera, P.E.of HDR,Inc.Mr.Butera also visited the site on April 27-28,2005 to inspect the hydroelectric facility.An analysis of his findings and a proposed scope of hydroelectric infrastructure renovation work is included in Appendix E of this report.Following is a summary of the proposed repairs and upgrades: e Replace concrete intake structure with new steel pipe and head box.Install new slide gate,screens,and screen cleaners. e Replace open wooden flume with new steel pipe pressure conduit.Install on existing trestle supports.Replace trestle on upper portion and repair trestle on lower portion. 19 Pelican Energy Infrastructure Projects September 13,2005 Concept Desiqn Report Alaska Energy and Engineering e Replace wooden surge tank with new steel tank to handle increased head from the pressure conduit. e Replace wood stave penstock with new steel pipe.Install on existing trestle supports.Replace walkway with new steel walkway. e Perform an evaluation of turbine operation including draft tube vent and modify as required. e Perform minor upgrades to the powerhouse. e Coordinate with VSW to provide support for new community water utility lines on penstock support trestles. While the existing facility has provided reliable service for a number of years the condition of many components makes its future service questionable.The effect of these repairs and upgrades will be to enable the system to provide long-term reliable service and to improve the overall efficiency and output.Additional modifications to the hydro control system are listed under section 5.2.5.This is because the control upgrades are required for proper interface with the new diesel generators. 5.4 Proposed Operating Scenario A long term agreement between Kake Tribal Corporation (current private owner of Pelican Utilities and Pelican Seafoods),and the City of Pelican (potential grantee of construction funding)will need to be drafted in order to define ownership and operating agreements for the new modular power plant,upgraded hydroelectric facility,and power distribution system as well as for the new fuel storage and handling facility.This agreement must be in place prior to drafting the business plan and beginning the final project design. Management responsibilities of the new tank farm include:maintenance and operation of all tanks,pumps,and piping systems;annual pressure testing of pipelines;maintenance and replacement of spill response equipment and supplies;and snow removal.These operating costs should be determined on a per gallon of throughput basis (as part of the required Denali Commission Facility Business Plan)and the price of fuel adjusted to cover the facility operating costs. 6.0 PERMITTING AND SPILL RESPONSE The proposed new tank farm,power plant and hydroelectric facility upgrades will be subject to Regulations of both State and Federal agencies including the Alaska Coastal Management Program,the Division of Fire Prevention,and the U.S.Environmental Protection Agency.Depending upon local conditions, additional permitting agencies including the U.S.Fish and Wildlife Service,the U.S.Army Corps of Engineers,the State Historic Preservation Office,and other divisions within the Alaska Department of Natural Resources may become involved.In addition,the hydroelectric facility operates under a license from the Federal Energy Regulatory Commission (FERC).Upgrade to the hydro plant will require review and approval by FERC. 20 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Engineering 6.1 Environmental Assessment An Environmental Assessment (EA)will be completed prior to construction of the proposed project.An EA is required for all projects that are federally funded or require a federal permit (such as a Corps of Engineers Wetlands Permit).The EA confirms there is no significant impact to the environment caused by the project.As part of the EA,a Coastal Zone Management Project Questionnaire will be completed and submitted to the Alaska Coastal Management Program. The Coastal Zone Management Project Questionnaire will help identify state or federal permits that may be required.A Corps of Engineers wetlands permit should not be required for construction as all fill material will be placed in uplands and not in navigable waters.However,the need for a permit will be investigated further with the Corps of Engineers early in the permitting phase. 6.2 Fire Code A Plan Review permit from the State Fire Marshal is required.Final stamped design drawings will be submitted for review and approval prior to construction. Plans will be reviewed for conformance with the International Fire Code and portions of related codes including the International Building Code and the National Electrical Code.In prior years the review process has only taken 3 to 4 weeks;however,recent projects have taken over 6 months.Generally site work and mobilization is allowed to proceed prior to approval but the permit must be in place prior to placement of tanks or similar installation.Plans should be submitted by December or January to ensure approval in time for spring construction. 6.3 Spill Response Because the new City bulk tank farm will have oil storage tanks in excess of 1,320 gallons and will receive delivery by marine vessel,it will be subject to U.S. Environmental Protection Agency and U.S.Coast Guard regulations.An Operations Manual and Letter of Intent will be prepared and submitted to the Coast Guard.An Oil Spill Response Plan will be prepared and submitted to both the Coast Guard and the EPA.The tank farm will require preparation of a Spill Prevention Control and Countermeasures (SPCC)plan.This plan will address all tanks with a capacity of 55 gallons or greater.The required Coast Guard and EPA plans will be prepared upon completion of facility construction as a coordinated package. Spill response gear including sorbent material and protective safety gear will be purchased and left on-site upon project completion along with a refurbished existing tank to serve as oil-spill contingency storage. 7.0 CONSTRUCTION PLAN The AEA/REG has a history of administering similar projects on a "modified" force-account basis.Force-account construction involves the owner or grantee acting as the employer and utilizing primarily local labor.This method tends to achieve a higher percentage of local hire and is strongly supported by many 21 September 13,2005 Alaska Energy and Engineering Pelican Energy Infrastructure Projects Concept Design Report communities and funding agencies.The highly technical nature of tank farm and power generation projects requires a limited number of workers with specific experience and expertise to be brought in for the project when not available locally.All work must be supervised and managed by a superintendent with extensive experience in the construction of rural fuel facilities.All specialty work, such as pipe welding and electrical installation must be performed by skilled craftsmen with appropriate certifications.An experienced construction manager will be required to recruit the necessary skilled labor,coordinate the construction team,and oversee procurement and project logistics.The design engineer will provide quality control through communication with the construction manager and periodic on-site inspections. 7.1 Local Job Skills An inquiry was made to the City for information regarding the availability of specialty skilled labor in Pelican.The table on the following page summarizes the results: Skilled Trades Number Available Certified Welder 0 Welder Helper Journeyman Electrician Electrician Helper Heavy Equipment Operator NM}NM]OO]NM]wMechanic/Helper In addition to the specialty trades listed,there are a number of local residents with general labor experience in various types of construction.It appears that at a minimum a project superintendent,a pipe welder/mechanical foreman,and a journeyman lineman will need to be brought into Pelican for this project. 7.2 The City provided the following inventory of locally available heavy equipment: Heavy Equipment Unit /Owner Make /Model #j}Year/Condition 1-1/2 ton flatbed-dump /City Ford F-350 2002 /good dozer /City John Deere 450 1979 /good excavator /James Phillips (see note)Hitachi EX100 n/a /good skid-steer with hoe,forks &bucket /City Case 1845C n/a /good 3 ton boom truck/Pelican Seafoods n/a n/a All of the equipment will need to be evaluated and serviced by a mechanic prior to the start of construction.Note that the excavator is located on the opposite end of the community from where the work will occur and will probably not be 22 Pelican Energy Infrastructure Projects September 13,2005 Concept Desiqn Report Alaska Energy and Engineering able to be used on this project.A loader/backhoe will probably need to be brought into Pelican for the duration of the project.The buried pipeline installation will likely require extensive trenching through bedrock.A rock saw should be brought in for this operation.In addition,the fence installation and modular power plant foundation construction will likely require drilling into bedrock rock so a rock drill will need to be brought in as well. 7.3 Material Sources Every effort will be made to minimize the quantity of gravel required due to the lack of a local borrow source and the difficulty of access to the site.However it is estimated that up to 500 cubic yards of gravel will be required for BFU gravel pad leveling and for buried pipeline bedding/backfill material.It is assumed that all of the gravel required will be barge delivered from Sitka or Juneau.Gravel can typically be delivered to the dock in Sitka or Juneau for approximately $20/yard. The cost of barging to the community is an additional $20/yard or more depending upon the size of the load.Proper coordination of the project can minimize delivery costs by bring in gravel with heavy equipment on the initial mobilization.Dump trucks should be brought in with the material so the gravel can be hauled and placed at the tank farm site at the time of mobilization. 7.4 Site Access &Delivery The second barge mobilization will need to include equipment capable of moving and placing the heavy power plant module and the tanks.The 15'-8"Wx41'-8"L power plant module will weigh approximately 65,000 pounds and will be the heaviest single item to be moved and placed.The 12,000 gallon fire rated gasoline dispensing tank,which will weigh approximately 35,000 pounds,will be the heaviest item to be moved up the steep grade along Coho Way to the proposed tank farm site.The normal barge landing site in Pelican is on the end of the breakwater at the eastern edge of the boat harbor.Large equipment cannot be moved across land from this area to the proposed project sites due to the size and weight restrictions of the boardwalk.Offloading the power plant module,fuel tanks,heavy equipment,gravel,and supplies from a barge in the vicinity of the proposed project work sites will be difficult due to limited beach access in this area.The water approach to the proposed modular power plant site is reported to be clear of rocks and accessible by barge.However,access to the construction site from this section of beach is restricted by a rock bluff that is approximately 15'high.A potential solution for staging at this location would be to use a high deck barge with long ramp to directly access the bench above the beach.However,a preliminary investigation indicates that the bluff height of 15'may be too tall for locally available ramp barges.It may be possible to place the module on this site by crane even if the other equipment,tanks and supplies must be offloaded elsewhere.Another potential barge offloading area is inside the harbor on the beach near the intersection of Coho Way and the main boardwalk (Salmon Way).However,this would require crossing the main boardwalk which supports the community water and sewer lines.In order to drive heavy equipment and to skid tanks across the boardwalk in this area the 23 Pelican Energy Infrastructure Projects September 13,2005 Concept Design Report Alaska Energy and Enqineering hand rails would have to be removed and the boardwalk will need to be heavily reinforced or protected with a ramp. 8.0 SCHEDULE The proposed project schedule is separated into two sections:Section 8.1,"BFU &RPSU Project Schedule",and Section 8.2,"Hydroelectric Project Schedule". 8.1 BFU &RPSU Project Schedule The following schedule has been developed on the basis of performing the majority of the work for the BFU and RPSU projects during spring/summer 2006. This schedule is contingent on timely approval of the plan by the project participants and Denali Commission as well as on funding availability.

The electrical upgrade unit cost of $2,170 per kW is within the Denali Commission benchmark cost range of $2,400 to $1,900 per installed kW for 601kW to 800kW capacity power plants. The hydroelectric upgrade unit cost of $1,987 per kW is within the Denali Commission benchmark cost range of $2,400 to $1,900 per installed kW for 601W to 800kW capacity diesel power plants.Without the proposed upgrades and repairs described in Appendix E of this report the hydroelectric facility is in danger of failure.It is assumed that the operation and maintenance costs of the hydroelectric plant are comparable to that of the diesel generators.Therefore, the hydroelectric upgrade project cost should also be compared to the primary benefit,which is the avoided fuel cost.The hydroelectric facility provided an average of approximately 2.5 million kWh of electricity for FY 2001 and 2004,or around 85%of the annual power demand within the community.Assuming a diese!generation efficiency of 12kWh/gallon of fuel,this represents an equivalent of 208,000 gallons of diesel fuel consumed.Based on an estimated fuel price of $2.50/gallon,the annual operation savings are estimated to be -approximately $520,000. 26 APPENDIX A CONCEPT DESIGN DRAWINGS DEMOLITION WORK THIS AREA SEE SHEET M2 FOR SEE SHEET M3 FOR NEW WORK THIS AREA UPGRADES TO PELICAN CREEK HYDROELECTRIC FACILITY SCHOOL SITE - REPLACE EXISTING TANK WITH NEW 1,000 GALLON DAY TANK SEE SHEET M6 FOR State of AloskaCommunityandEconomic DevelopmentDepartzentofSCALE:1"=400' ove:SEPT 05 SHEET DRAWN BY:JTD DESIGNED By:BCG FILE NAME PELI-cDR-M1 |M ] LISIANSKI INLET PELICAN BULK FUEL STORAGE AND POWER SYSTEM UPGRADE JECT: OVERALL COMMUNITY SITE PLAN L EXISTING STANDS TO BE DEMOLISHED FUEL DOCK EXISTING \ DISPENSERS AND MARINE HEADER TO BE DEMOLISHED TRUCK FILL HOSE EXISTING FUEL TANKS TO BE TAKEN OUT OF SERVICE THREE EACH EXISTING 3°6 FUEL PIPELINES TO BE DEMOLISHED BOAT HARBOR \\ LISIANSK]\INLET iPELICANBULKFUELSTORAGEDRAWNBY:UTD SCE:1"=40!Department of comstattyet,tones,AND POWER SYSTEM UPGRADE wescun ov BCG [owe SEPT 05 (Hy Deparypent of CommitSFA Eaenemic DevelopmentALENAMESHEETOFRuralEnergyGroupSALAS KEXISTINGSITE/DEMOLTION PLAN PELI-CDR--M2 M2 6 pris Ne ON cakcenertnorn Lait Bivd,@amm ENERGY AUTHORITY [=A.-phe -=-pe Ty Si1;;' | oy -- C || tor1 =|ure =|ort eo | F Zl urs |Lor2._|:_A o>'toe y LOTSPScanr---4 '1 Q a LOT 4 LOT 3 H{oo :LOT 6 Q |Ay | LOT 2 ;; ' |PROPOSED"ee /THREE|EACHPROPOSEDNEWCITYTHREE |NEW CITY t TANK FARM!|NEW 3 re arent aPLANT|IFARM -SEE SHEET M4 ||||b4----- PROPERTY FOR SITE PLAN |Lor 9 DISTRIBUTIONOWERaa)(oe S INTERMEDIATE -TANK,TYP(2) ad SEAFOOD =RR PLANT ™ ™a"LOT 2 /{Ss \A™,DOCK-MOUNTED WAtot3./3°6 FUEL"PIPELINES AND «NEW GASOLINE /ELECTRICAL WW DIESEL BULK TRANSFER .cA na 1°=120'Ale BOUNDARY NEW MODULAR FOWER|._ SEE SHEET E2 syriMp WAY 1 FOR BARGE _.:_.-__..__FILL,FUEL -_f'\\\Pf tor oca_Loti:LOT 1A 9)en 3 |LOT 4 |TRUCK;FILLSe uss 2861 /7= @ /// Lor 1 &/™. ae fener tenets tie weedoS._|USS 2861 /(or 2 AND rdh t INTERMEDIATE|7 ||TANKS LOT 5 SUPPL',:ROUTE |WITH NEW nT )ELECTRICAL 1 POWER!&-@ |CONTROLmSCONDUIT\7 NEW TRUK \LOADING a Lor 8 \ we USS 281S- aw NEW 2”¢BURIED #2 DIESEL BRANCH PIPELINE FOR &MARINE.HEADER CaN Z i 2 YN Va eS 7:PELICAN BULK FUEL STORAGE AND POWER SYSTEM UPGRADE ”'prawn ey:JTD SCNE 1°=120 State of AlaskaDepartgentofCommunityondEconomic Development NEW WORK PLAN pesicneD ay:BCG ove:SEPT 05 |*AIDEA/AEA*Rural E GrniWisetOF|yA uel Sty Son,(ALASpeti-cor-M3 |M3 -s ae focrorones Noska TANK SCHEDULE TANK|NEW |NEW/|TYPE |FUNCTION |#2 DIESEL |#1 DIESEL |GASOLINE#|OWNER |EXISTING |(2)CAPACITY(1)|CAPACITY(1)|CAPACITY(1) #i_{Ciy_[NEW DW__|BULK 20,000#2 [City |NEW DW [BULK 20,000 #3 [Clty [NEW DW [BULK 20,000 #4 [Cy [NEW FR _[DISPENSING 12,000#5 [City |NEW DW__[INTERMEDIATE 6,000#6 |P.SFDS |NEW DW__|INTERMEDIATE 6,000#7 |PCSD |NEW DW |DAY TANK 1,000 PROJECT STORAGE CAPACITY BY PRODUCT 53,000]20,000 12,000 PROJECT TOTAL GROSS STORAGE CAPACITY 85,000 NOTES:1)ALL CAPACITIES ARE GROSS SHELL CAPACITY IN GALLONS 2)DW =DOUBLE WALL,FR =TWO-HR FIRE RATED \APPROXIMATEEDGEOF x EXISTING !LEVEL PAD, GASOLINE TANK #4 >t 6'HIGH |= ¥CHAIN LINK |° FENCE ;S|#2 DIESEL TANK #3 |SEE i SHEET r !TANK »-b PreeFrAPPROXIMATE#2 DIESEL TANK #2 FARM 3”BURIED $+!!;{{EXISTING ;PIPING DIESEL,#2 1 4}GROUND PLAN DIESEL AND i= !'CONTOUR CASOLNE = +\ \\ELEVATIONS #1 DIESEL TANK #1 FILL/DISTRIBUTION |LtMo:-PIPBLINES o_o oerysayiaaienieieskena |\\an /¢||N N /¢ N /y || |Sv Sone e.''iieeTeeae .\.i y ,det thpeeTeea y _//t v7 il[a Sia ne On ted ,ye"imeOTTroares__"\Y (Yo il!

Background The Pelican Creek hydroelectric project was constructed on Pelican Creek in the early 1940's.The project has a dam,intake,flume,surge tank,penstock,powerhouse and tailrace.Each of these components is described below along with potential recommended improvements.These recommended improvements are summarized and a cost estimated for each.Table 1 summarizes the existing characteristics of the Pelican Creek Hydro Project.

Site Visit The project site was visited by Bob Butera,P.E.on April 27-28,2005.Accompanied by Plant Engineer Tom Whitmarsh the general condition of the dam,intake,flume,penstock,and powerhouse was assessed.Coring of wood structures was done to assess the condition of the wood in the flume and penstock trestles.The turbine and generator were not assessed as they are relatively new.The controls were not assessed as this task was done by others. Dam The existing dam is a rock filled timber crib structure 135 feet long and 22 feet high.It has 3”thick x 8”or 12”wide planking on the lake side of the dam and 3”x 8”hem-fir splined planking on the top surface.It was constructed in 1941.The timbers are yellow cedar.Because of high water at the time of the site visit the timbers were not able to be cored but are expected to be sound based on appearance and coring done in similar timbers in the flume trestle. Dam upgrades were designed in 1993 by Polarconsult and constructed in 1996 to 2002 by Tom Whitmarsh.These upgrades primarily included the installation of steel bracing to support the downstream face of the dam.Earle Ausman of Polarconsult Alaska,Inc.(Polarconsult)stated that the design of this steel structure allows future upgrades to increase the height of the dam by 7 feet. Dam upgrades also included widening the dam spillway,replacing the wing walls on the sides of the spillway and replacing the deck planks and top deck support timbers.These were completed in 2000 to 2002.Planned upgrades were to include replacement of the existing upstream face planking but the planking was found to be sound and only a portion was replaced. Based on the 1991 Polarconsult drawings the dam has an intake elevation of 136.4 feet and a spillway elevation of 142.6 feet.The flashboard elevation was estimated to be approximately 148.6 feet. The existing storage at the dam is minimal and the project is a run of the river project.Surveying would be required to determine the additional storage that might be available if the dam height were increased. Intake The existing intake is a 5 foot wide x 4 foot high concrete box structure that connects to the downstream wooden flume.There is a steel trash rack at the intake.Submergence of the intake is minimal (approximately 2 feet from the top of the intake box)and results in a vortex.At the downstream end of the intake structure there is a 54 inch steel slide gate.The slide gate is the same size as the concrete flume intake,but it only opens for the bottom 18"and operation requires the use of jacks.The intake gate does not seal tightly.The concrete at the interface between the intake structure and the flume is deteriorated. HDR Alaska,Inc.2525 C Street Phone (907)644-2000 Page 2 of 7 Suite 305 Fax (907)644-2022 Anchorage,AK 99503 www.hdrinc.com A design for an intake upgrade was done in 1991 by Polarconsult.This design was reviewed and found to be appropriate.It replaces the existing intake structure with a 54”steel pipe and a headbox with slide gate located 60 feet downstream from the dam.The 54”pipe would fit inside the existing concrete flume and would be grouted in place to avoid disturbing the dam.Power was recently run to the intake area so the slide gate could be electrically operated.The pipe would connect 'to the flume.The head box should be increased in size to accommodate a set of screens and screen cleaners. The reservoir would need to be drained for this installation.There is no reservoir drain so draining of the reservoir would likely be done using multiple small diameter siphons at a low water period of the year. Flume The existing flume connects the dam to the surge tank.Based on the 1991 Polarconsult drawings it is a total of 727 feet long and consists of 113 feet of 5 foot wide x 5 foot deep (inside dimensions) timber flume from the intake to a rock tunnel,91 feet of rock tunnel (dimension unknown,assumed dimensions of 5'x 5”)and 523 feet of 5 foot wide x 4.5 foot deep (inside dimensions)timber flume from the tunnel to the surge tank.The flume is supported on a timber trestle.The overall slope of the existing flume is 0.0022 feet per foot,although the grade is not constant. The 113 feet of flume and trestle from the intake to the tunnel and 95 feet of flume downstream of the tunnel was installed in 1941 and is in extremely poor condition due to rot.The portion of this trestle immediately downstream of the intake spans a gap and the supports are failing.This section of flume and trestle should be replaced. The remaining 428 feet of the wooden trestle was installed in 1941 and is constructed of yellow cedar.A sketch of a bent of this trestle is attached.The trestle legs,cross members and sills were cored and found to be in excellent condition.Six bents of this trestle were washed out when the flume failed in 1988.They were replaced but may need some additional work.Approximately 20% of the diagonal bracing may also need to be replaced. The remaining 428 feet of flume was replaced in 1976-77 but is also in poor condition.The entire flume should be replaced. A number of alternatives have been considered for replacement of the flume.Each must provide a minimum flow equivalent to the combined rated turbine flows of 77.5 cfs plus 3.5 cfs for the City water supply or approximately 80 cfs.The alternatives are as follows: 1.Replace with a pipe supported by rock bolts from the rock wall.This alternative would need to use polyethylene pipe to conform to the existing rock wall.With a pressure pipe system the pipe would be approximately 4 feet diameter.Polyethylene pipe in this size would be difficult to construct due to its weight and the difficulty of butt fusion in this location.Since the existing trestle is in good condition this alternative was not considered further. 2.Replace the wood flume with a new wooden flume.This alternative was rejected because it would have the same leakage issues as the existing flume.The cost of this alternative was previously estimated by Tom Whitmarsh and found to be of greater cost than other flume options. 3.Line the existing wood flume with a fabric liner.This alternative was rejected because the existing wood flume is in a partially decayed state.Preservation of wood is aided by being HDR Alaska,Inc.2525 C Street Phone (907)644-2000 Page 3 of 7 Suite 305 Fax (907)644-2022 Anchorage,AK 99503 www.hdrinc.com continuously saturated with water and installing a liner would dry out the wood and accelerate the decay. 4.Line the existing wood flume with an aluminum liner.This alternative was rejected because the existing wood flume is in a partially decayed state. 5.Replace the wood flume with an aluminum flume.This alternative would replace the existing wood flume with an aluminum half circle flume of equivalent capacity.A 6 foot diameter half circle pipe has the capacity to provide the rated flows to the existing turbines. 6.Replace the wood flume with an open channel pipe.This alternative would replace the existing wood flume with a steel pipe of equivalent open channel capacity.A 5 foot diameter pipe has the capacity to provide the rated flows to the existing turbines.This alternative was not considered further because if a pipe were to be used,the system should be converted to a pressure conduit to take advantage of additional existing head. 7.Replace the wood flume with a pressure conduit.This alternative would replace the existing wood flume with a pipe with the capacity to handle the rated turbine flow with minimal head loss.A 48 inch diameter pipe would handle the flow with only 2%loss.This alternative would have the immediate benefit of 3%additional generation capacity from the additional 3 feet of head.It would also provide the capability to gain further additional generation capacity if the dam were raised in the future. Alternative 7,replacing the wood flume with a 48 inch diameter pipe was selected as the preferred alternative for the purposes of this technical memo.Further design work should be done to determine the optimum size for the pipe as cost vs.capacity may suggest a different size. Steel pipe with a 0.1875 inch wall thickness and epoxy coating and lining would be the preferred pipe since it is light enough to move 20 foot sticks by helicopter,has high bridge strength and can be easily assembled.HDPE pipe was also considered but HDPE has a high coefficient of thermal expansion which would be difficult to deal with on the existing trestle.HDPE also does not have the favorable bridging capability of steel.Steel pipe is available in either a lap welded slip joint or a rubber gasket joint.Further design should evaluate the constructability of each joint type.For the purposes of this report we have selected the gasketed joint as it will be easier to assemble.In order to resist the small thrust forces that will exist in this pipe the gasketed pipe joints could be skip welded. The new pipe would be placed on the sill beams of the existing trestle.The existing wood flume would be dismantled and salvageable planks would be used to construct permanent and temporary construction walkways on both sides of the pipe.This retrofit is shown on the attached sketch. Since the tunnel may not be competent enough to operate as a pressure conduit,we have assumed that it will be lined with steel pipe.The size of the tunnel should be verified. Surge tank The surge tank connects the flume to the penstock.There is a set of screens with screen cleaner immediately upstream of the surge tank and the surge tank also operates as a settling basin for stones that may get past the screens.Domestic water for the City is taken from the end of the flume where it meets the surge tank where there is a separate set of screens with finer openings. The surge tank was constructed in 1941 and was rebuilt in 1982.The rebuilt surge tank is constructed on the original concrete foundations.The tank is constructed of 2x6 cedar timbers HDR Alaska,Inc.2525 C Street Phone (907)644-2000 Page 4 of 7 Suite 305 Fax (907)644-2022 Anchorage,AK 99503 www.hdrinc.com stacked on the flat with woven corners.It is in good condition although the concrete foundation requires re-pointing. If the flume were converted to a pressure conduit the surge tank height would need to be increased to handle the increased head.Further engineering would need to be done to determine if this were possible.If not possible,the existing wooden surge tank could be replaced with a steel one.This may be the best alternative as it would best provide for a future increase in dam height. Penstock The existing penstock connects the surge tank to the powerhouse.It is a 36 inch inside diameter wood stave pipe approximately 330 feet long with a slope of 36%.The penstock is supported on a wooden trestle. The wooden trestle was installed in 1941.The trestle is constructed of yellow cedar.The trestle legs and sills were cored and found to be in excellent condition.Approximately 10%of the diagonal bracing should be replaced. The existing penstock was installed in 1941 and is in extremely poor condition.It is leaky,eroding and wood tends to peel off along the grain structure.End joints on wood stave pipe are joined with steel H shaped connectors and these can cause turbine damage when they fail.The penstock was not cored so its soundness is unknown.The entire penstock should be replaced. A penstock replacement design was done for Pelican Seafoods by Polarconsult in 2001.This design is for a new 36”diameter steel penstock and a new steel trestle and walkway.An engineer's estimate was not available for this design.The construction sequence for this new penstock would be to demolish the existing wood stave pipeline,construct the new steel pipeline on top of the existing trestle,construct the new steel trestle beneath the new pipeline and then demolish the existing wooden trestle. Because the existing wooden trestle is in sound condition a new steel penstock can be installed without the expense of a new steel trestle.Ring girders and the central anchor block can be included on the pipeline so that if a new trestle is needed in the future it can be connected to the pipeline per the Polarconsult design.The existing walkway would be replaced with a steel one using grip strut plank. Replacing the wood stave penstock with a 36 inch diameter steel pipe and retaining the existing trestle was selected as the preferred alternative for the purposes of this technical memo.Further design work should be done to determine the optimum diameter for the pipe as cost vs capacity mayrecommendadifferentdiameter. Steel pipe with a 0.1875 inch wall thickness was shown in the Polarconsult design.This pipe would be epoxy coated and lined.To limit helicopter loads to 2000 pounds this pipe would need to be ordered in 20 foot lengths.The penstock would need to have welded joints and a lap welded slip joint is preferred as it would be easiest to assemble. Powerhouse The original powerhouse was constructed in 1941 but burned to the concrete foundation in 1982.A new powerhouse building with new mechanical and electric was constructed on the existing concrete foundation in 1982-84.The building is 22'x 33',appears adequate in size and is in good condition. HDR Alaska,inc.2525 C Street Phone (907)644-2000 Page 5 of 7 Suite 305 Fax (907)644-2022 Anchorage,AK 99503 www.hdrinc.com There are two turbines with the characteristics shown in the following table: Characteristic Turbine #1 Turbine #2 Type Francis,horizontal shaft Francis Manufacturer Barber (1984)Cornell (1984) Speed 900 RPM 1800 RPM Rated Net Head 120 feet 120 feet Gross Head 116 feet (108 to turbine centerline,8 feet to |116 feet base of draft tube Flow at Rated Head 55 cfs 12.5 Output at Rated Head |550 kW 100 kW The main generator is a 600 kW unit manufactured by Kato Engineering.The turbine,generator and controls were not inspected in detail but Mr.Whitmarsh stated that they were functioning without problems.The existing draft tube is vented to prevent it from "oilcanning”and making a lot of noise.This venting prevents the turbine from using its full head.Surging was also noted along the penstock.These two observations may be linked and may be due to cavitation or to roughness in the penstock.They should be assessed by a turbine specialist. If the draft tube venting can be resolved this could provide approximately 6%increase in project head. In addition there are a few other minor powerhouse repairs/modifications that should be made. e Self cleaning strainers should be installed for the turbine bearing cooling water.Cleaning the existing strainers is the most frequent reason for plant shutdowns. e Install an auto dialer in the head level alarm system. The entrance boardwalk is nearing the end of its useful life and should be re-planked. The concrete powerhouse foundation is beginning to show some surface deterioration.It should be power washed,repaired in some minor locations and resurfaced using a concrete grout. e The concrete tailrace is beginning to show some surface deterioration.It should be power washed,repaired in some minor locations and resurfaced using a concrete grout. e Relocate the water treatment chlorine injection facility.A chlorine leak could cause corrosion of the mechanical equipment in the powerhouse. Permitting The Pelican Hydroelectric Project is owned by Pelican Seafoods and is licensed by the Federal Energy Regulatory Commission (FERC).It is FERC Project No.10198.The most recent FERC inspection was done in 2002.In the original license to operate FERC requested repairs be done to the dam and intake.The dam repairs have been completed and on October 15,2004 Pelican Seafoods requested a 3 year extension of time to complete their work on the intake and flume between the dam and the tunnel.On February 10,2005 this extension of time was granted. The project has an instream flow requirement of 3 cfs downstream of the dam for fisheries.This flow is not currently measured but is estimated.A bypass pipe from the flume or pipe next to the dam can be sized to provide this instream flow. HDR Alaska,Inc.2525 C Street Phone (907)644-2000 Page 6 of 7Suite305Fax(907)644-2022 Anchorage,AK 99503 www.hdrinc.com Pelican Water Project The City of Pelican is presently completing a Water and Sewer Preliminary Engineering report.The purpose of the report is to plan water and sewer improvements that will bring the City's water system into regulatory compliance and to guide development of necessary and desired water and sewer improvements.This report is being prepared by HDR Alaska. This project is relevant to the hydroelectric project because the existing City water supply is taken from the downstream end of the flume of the hydroelectric project.Domestic water is then conveyed by a separate 12 inch diameter PVC pipe to the City water system.The PVC pipe is attached to the penstock wood trestle.The City has water rights to obtain 3.5 cfs of water from Pelican Creek.Presently they use an average of 500 gallons per minute (approximately 1 cfs).This volume of water is primarily due to water bleeding done to prevent pipe freezing.If the water system is modified to a looped system the domestic water flow rate would decrease greatly. Concept level work assumes that the City water source will remain from Pelican Creek and will continue to be taken from the hydroelectric project flume or pipe upstream of the surge tank (tap location is upstream of surge tank to allow shutdown of the penstock without affecting the City water supply).The 12 inch PVC line will likely be replaced and a new treatment plant will likely be located adjacent to the hydroelectric powerhouse. Because the City water supply is taken from the hydroelectric flume it is critical to the water supply that the flume be rehabilitated. Construction Cost Estimate The estimated construction cost for the primary improvements necessary are summarized in the following table and a detailed cost estimate is attached.We have assumed that the plant would be completely shutdown for a 12 week period of construction and thus have included a cost for replacement diesel generation of power (at a present cost of $2.56 per gallon).We also assumed that the City water supply could be taken from further downstream of the dam on Pelican Creek and temporarily pumped to supply domestic and commercial needs.Labor costs are based on a force account rate of $35 per hour.A 30%contingency is used based on the concept level of this work. Description Estimated Cost Mobilization,replace intake,new head box,replace flume with steel pipe,replace $582,000 surge tank,replace penstock with 3'diameter steel pipe,minor repairs to trestles, minor powerhouse repairs and upgrades and turbine evaluation. Contingency 30%$175,000 Replacement diesel power during construction $136,000 Total project construction cost $893,000 The total project construction cost increases to approximately $1,000,000 if a blended wage rate of $60 per hour is used. Summary The existing hydroelectric plant provides the majority (85-90%)of the power to the community and also is key to the supply of domestic water.It is a well thought out and well operated system but is in danger of failure due to the decrepit conditions of portions of its water conveyance system.Other major components of the project,the dam,flume and penstock supports,powerhouse,turbine, generator and tailrace are generally in good condition.

We arrived in Pelican by float plane at 11:30 AM.Upon arrival we went directlytotheCityofficetomeetwithMayorKathleenWasserman.After a brief discussion she directed us to Pelican Seafoods plant engineer Tom Whitmarsh. Mr.Whitmarsh has been the chief plant engineer for 28 years and is responsible for maintenance and operation of Pelican Seafoods cold storage and tank farm as well as the Pelican Utility Company.Both Pelican Seafoods and Pelican Utility Company are subsidiaries of Kake Tribal Corporation.Mr.Whitmarsh gave us a complete tour of the community as well as a thorough overview of the bulk fuel and electric utility facilities. The following summary report includes information on : e Pelican Seafoods Bulk Fuel Storage Facility e Local Power Generation and Distribution e Pelican Utility Company Hydroelectric Plant e Pelican Seafoods Diesel Generatorsand Cold Storage Facility e Pelican School Fuel Storage Tank Pelican Seafoods Bulk Fuel Storage Facility: The Pelican Seafoods bulk fuel storage facility consists of six in-service and oneout-of-service vertical steel bulk storage/dispensing tanks,a three product Pelican Power and Fuel Facilities Site Investigation Trip Report marine header,a three product marine dispenser,a #1 diesel bulk transfer (truckloading)hose connection,and multiple above ground distribution and transferpipelines.The tank farm is located on the hillside above and to the east of thefueldock.Tank farm access is by a covered wooden stairway from the main cityboardwalk.The facility provides storage for virtually all the #2 diesel,#1 diesel,and unleaded gasoline received by the community.The fuel is used to generatepowerwhenrequiredtoaugmentthehydroelectricplant,to provide for PelicanSeafoodsin-house operations,as well as to dispense fuel to the fishing fleet andgeneralpublic.; The total gross shell capacity of the six in-service bulk storage/dispensing tanksisapproximately60,000 gallons of #2 diesel,40,000 gallons of #1 diesel and -20,000 gallons of unleaded gasoline.The tanks are approximately 50 years oldbutappeartobewellmaintained,with good paint except for some loose paintandrustalongthebottomseams.The condition of the tank bottoms is suspectduetotheageofthetanksbutnothicknesstestinghasbeenperformedonthemtodate.The tanks are equipped with normal vents,emergency vents andmanways.They have 3”flanged bottom connections with flanged steel plugvalvesand1"threaded steel PRV jumpers for pipeline pressure relief..Themanifoldpipingappearstobeingoodconditionandiswellsupportedbuttherewerenoflexesbetweentankconnections.The tanks are supported on concretebaseswithina98'long x 20'wide x 2'-8"high heavy timber dike.In the late1990's the dike floor was covered and sealed to the base of the tanks with an application of "Fusion Crete”,a lightweight cement material.A dike membranelinerwasinstalledontheverticaldikewallsandsealedtothedikefloorwith metal flat bar,sealant and stud anchors.The dike appears to be liquid tight butdoesnotprovidesecondarycontainmentforthetankbottoms.. There are three each 3"diameter HDPE coated welded steel bargefill/distribution pipelines that run from the marine header to the tank farm,supported above grade on the dock,boardwalk and tank farm access stairstructures.The HDPE coating appears to be in good condition.All elbows and pipe joints appear to be well sealed with heat shrink tape. The three product marine header is located on the end of the fuel dock.Eachbargeconnectionhasa3"quick disconnect hose coupling,a 3"flanged steelcheckvalve,and a 3"flanged steel plug valve.There is a single aluminum drippanthatservesallthreemarineheaderfillconnectionsandappearstohaveadequatecapacitytomeetthe84galloncontainmentrequirement.The marinedispensersarealsolocatedonthefaceofthefueldockandaregravityfedwith2"welded steel branch pipelines off of the main 3"barge fill/distribution pipelines.There is a bulk transfer hose and meter located along the main boardwalk nearthefueldockthatallowsforbulkloading#1 or #2 diesel into drums and portabletanksfordistributionwithinthecommunity.A 2"bulk transfer pump with meterlocatedinasmallenclosureonthefueldockisusedfortransferring#1 or #2dieselto500gallonresidentialstyledaytanksatseveralbuildingsaswellastoa6,000 gallon day tank at the power plant.These various tanks are supplied by anetworkofweldedandthreadedsteelpipelinesfrom1"to 2"in diameter routed along the main boardwalk and building stairways. Local Power Generation and Distribution: The main source of electricity for the community of Pelican is a hydroelectricfacilityownedandoperatedbythePelicanUtilityCompany.Diesel-electricgeneratorslocatedinthePelicanSeafoodsengine/refrigeration room provideadditionalpowerforthecommunityasrequired.The electric power demand inPelicanvariesgreatlydependingonthestatusofproductionattheseafoodfreezerplant.Due to financial difficulties,all fish buying and freezing operations Page 2 of 4 Pelican Power and Fuel Facilities _Site Investigation Trip Report were terminated last year.The only refrigeration load at the plant for the pastyearhasbeenforsomeiceproductionandasmallamountofproductheldincoldstorage.Including this level of freezer plant activity,the total communitydailypeakelectricalloadhasrecentlybeenaveragingapproximately280kW.Other than during occasional winter season periods of low water flow,this load iswellbelowthepeakcapacityofthePelicanUtilitieshydroelectricplant,which isapproximately550kW.According to Tom Whitmarsh,the hydro plant is currentlysupplyingaround85%of the total annual community electrical demand. Overhead electrical distribution for the main portion of town between the Pelican Seafoods and the hydroelectric plant is 2400V delta-connected 3-phase,with2400Vsinglephaseextensionsbeyond.The current residential rate charged byPelicanUtilitiesis$0.17/KWH.. Pelican Utilities Hydroelectric Plant: The hydroelectric installation consists of a diversion dam,a 1/4 mile long openflume,a trash screen/reservoir,a 36"diameter wood stave penstock,and a hydroelectric plant.The diversion dam is located on Pelican Creek approximately 1/4 mile from the town site.The hydro plant is located directly offthemainboardwalkintheeastpartoftown.The diversion dam,flume,and original hydro plant were constructed in the early 1940's.Heavy timbers milledonsitefromlocalyellowcedarwereusedtoconstructthediversiondamandflume.A considerable amount of maintenance and repair has been done over-the years but much of the original timber construction remains and ranges inconditionfromgoodtopoor.In the 1990's heavy steel Il-beam columns wereattachedtothefaceofthetimberdamandbracedwithsteelI-beam kickers. Many of the flume's original fasteners and cross ties have been replaced withnewhardware.In the 1970's and 80's many of the flume side timbers werereplaced.There are plans to replace some of the remaining original flume withflangedaluminumsectionswhenandifafundingsourcecanbefound.Theopenflumeterminatesintothetopofatimberconstructedreservoirthatwasbuiltinthe1980's.Water enters the reservoir through a trash screen with an auto-clean grate.The original 1940's era wood stave penstock feeds water fromthereservoirdowntothehydroelectricplant.The penstock is in poor condition,with many leaking sections.The interior of the penstock is also starting todelaminate,causing major problems when wood pieces attempt to pass through.the turbine.Polar Consult has prepared a design for a new steel penstock buttheprojectisonholdduetolackoffunding.In the 1980's a separate trashscreen/reservoir with auto-clean grate and 6"diameter HDPE pipeline wasinstalledforthewaterutilitythatisco-located in the hydro plant.The City ofPelicannowownsandoperatesthewaterutilityforthecommunity. The current hydroelectric plant was built in the 1980's when the original plantburnedtotheground.Power generation is 480V 3-phase.The prime hydro unitisagoverned737HP,Type HFSC Barker Hydraulic turbine coupled to aRelianceElectricgeneratorwithanameplatecapacityofGOOkW.The maximumusableoutputofthisunitisrestrictedtoapproximately500kKWduetotheexistingpenstockdiameterandavailablehead.There is also a second ungovernedpumpturbinemountedtoanominal100kWGEInductiongeneratorwithamaximumuseableoutputof94kW.Switchgear includes a section for each turbine and a distribution section.Two each 10kVA dry pack transformersprovidefor120/240V 3-phase station service power. Pelican Seafoods Diesel Generators and Cold Storage Facility: Page 3 of 4 Pelican Power and Fuel Facilities Site Investigation Trip Report There are a total of five Caterpillar generators located in the engine/refrigerationroomatthePelicanSeafoodsfreezerplant.These units range from 100kW to400kWwithacombinednominalcapacityof1,360kW (1,150kW usable).Allunitsrunat1,.800RPM and power generation is at 480V 3-phase.No enginenameplatedataisvisiblebutallofthegeneratorsappeartobeolderunitsinrunningcondition.Switchgear includes a section for each generator and adistributionsection.The system also allows the-diesel generators to be run inparallelwiththehydroelectricturbinesasrequired. There is a 6,300 gallon single wall welded steel diesel storage tank locatedbehindtheseafoodplant.This tank is pipeline filled from the transfer pumplocatedonthefueldock.It feeds the generators through an insulated,heat-traced 1-1/4"welded steel pipeline.For winter operations,#1 and #2 diesel fuelaremixedinthistankforwinterblendfuel.This tank also provides fuel for spaceheatingofthestoreandbunkhousethroughcopperfueloilsupplyandreturnlines.The tank is supported on heavy timbers and is contained within an oldcementbuildingfoundation.There is no dike liner,emergency vent or securityfencing.The tank is in fair condition with some blistering and peeling paint. The freezer plant has a 2-stage ammonia refrigeration system with 5 each highstagereciprocatingcompressorsand4eachboosterstagerotarycompressorslocatedintheengine/refrigeration room.The compressors are all electric motordrivenandhaveacombinedtotalof740horsepower.Under full production,theplanthasthecapabilitytoblastfreeze100,000 Ibs of frozen product and produce75tonsoficeina24hourperiodwhileholdingseveralhundredthousandpoundsoffrozenproductincoldstorage.It is estimated that the peak electricaldemandofPelicanSeafoodsincludingprocessing,blast freezing and coldstorageisinexcessof1,000kW.

Some disadvantages of locating the new tank farm on this site are the limited available - space,the close proximity.of existing buildings/adjacent parcels,vulnerability to tsunamis,and the requirement of constructing three new pipelines (approximately 5,000 _feet total length)through town along the boardwalk to the fuel dock.The Department of - _Transportation (DOT)has de-rated the carrying capacity of the boardwalk structure so that separate pilings would likely have to be driven adjacent tcto the boardwalk iin the tidalareaforsupportofthenewfuelpipelines.;. Of the three sites investigated,the preferred location for the new tank farmis the City-owned school reserve (old quarry)site on the dump road.This site has adequate'-available space and good construction access.It would not require-additionalboardwalk-mounted pipelines for fuel distribution.It is in the vicinity to the fuel dock : andis close enough to the proposed new power plant and the seafoodd plant to allow forpipedfueldelivery.3.Proposed Scope of Hydroelectric Renovation Work:All available hydroelectric data and information gathered on this and previous site Visits_has been forwarded to hydroelectric generation specialist Bob Butera,P.E.of HDR,| Inc..Mr.Butera is also scheduled to visit Pelican in early May,2005 to tour the. hydroelectric facility.An analysis of his findings and a proposed scope of hydroelectric ©renovation work will be included in the Pelican.Energy Infrastructure Upgrade .Conceptual Design Report (CDR).; _.4,Proposed Scope of Power Generation and Distribution Upgrades: -A new power plant with generation capacity to meet peak community loads plus baseloadsattheseafoodplantisproposed.It will include three generators (sizes to be. determined),programmable automatic paralleling switchgear,remote radiators with variable speed control,a fire suppression system,critical grade exhaust silencers andanautomaticfilldaytankaswellasallrequiredenginecoolantpipingandventilationequipment.It will come pre-assembled in a 16'°W X 50°L modular skid-mountedbuilding.-- Page 2 of 3 oo Pelican Energy Infrastructure Projects Preliminary Recommendations: "15.New Power Plant Location Options: |:Proposed community power distribution upgrades include: °feeder from the new power plant to seafood plant|°emergency backup power feeder from the seafood plant generators to the newpowerplant-., ©paralleling capability between the hydro facility and the 1new power plant7_replacement of final three power poles at east end of town with regulation height :'poles . . e extension of 2,400V primary wires to three new poles°e new secondary service transformer and service to customers5 affected by lineextension(approximately four services), °'extension of distribution to new tank farm site + Two potential sites were investigated for the new power plant:1)the breakwater area7.and;2)the bank above the existing diesel power plant at the seafood plant..The breakwater site consideredis on city property in the area of the shop building andwastetreatmentfacility.Some disadvantages of locating the new power plant on this___site are the limited available space,the distance from the preferred tank farm location for piped fuel delivery,vulnerability to tsunamis and distance from existing community_Step up transformer bank.:_The preferred location for the new power plantis on property currently owned byPelicanSeafoods,adjacent to the existing diesel power plant and existing communitystep-up transformer bank.This site has adequate available space and good construction access.Itis close enough to the proposed new tank farm site to allow for..piped fuel delivery.,Please review the issues presented and call David Lockard at 269-4541 to discuss or7 |fax your comments to 269-3044.In order to keep the CDR on schedule we need toreceiveallcommunitycommentsnolaterthanJune1,2004.|look forward to working:awithyouonthisproject.
