On September 22,2004,David Lockard of AEA/REG,John Dickerson of AE&E,and Vince Webster of LPSD traveled to Levelock to meet with local residents and tour the community.The purpose of the site visit was to observe the existing energyrelatedinfrastructureandassessthefuelandpowerneedsofthecommunity.After a complete tour of the school mechanical building,power plant and all communitybulkfuelfacilities,a meeting with members of the Village was held.Trevor Krupa ofAE&E made an additional site visit on January 23 and 24,2006.While on site,Mr. Krupa met with council vice-president and school maintenance person Greg Andrew Jr. The Village tank farm is in poor condition and in need of replacement.The proposedVillagetankfarmsitehasadequateareaandsetbacksforconsolidationofall required Village fuel storage,bulk transfer,and fuel dispensing. None of the existing Village tanks are suitable for reuse.Six new tanks will be required to meet the projected fuel storage and dispensing requirements for thecommunity.The Village bulk tank farm will have a gross storage (tank shell)capacityof120,000 gallons of diesel fuel,and 18,000 gallons of gasoline for a combined gross storage capacity of 138,000 gallons.Fuel will be delivered to the bulk tank farm by barge via a marine header and fill pipelines. The Utility power plant is centrally located in the town site near the school.There is an existing power generation heat recovery system with pipelines to the school complex.The power generation and heat recovery equipment are in poor conditionandinneedofreplacement.The renovation will include the purchase and installation of three new generators,new switchgear,new engine cooling system andnewheatrecoveryequipment,as well as miscellaneous mechanical and electrical work.The power plant building is approximately 20 years old and appearsstructurallysoundbutwillrequirenewsiding,new roofing and a complete interior renovation. The proposed project schedule calls for design and permitting to be completed bythewinterof2006/2007,construction from April through August 2007,and the facilityfullyfunctionalbySeptember2007. The total project cost including all design,supervision,inspection,permitting,and a15%contingency is estimated to be $2,520,158.The estimated cost of the bulk fuelupgradeportionis$1,342,319 which equates to a unit cost of $9.00 per gallon basedonagrossstoragecapacityof138,000 gallons (design and _constructionadministrationcostsnotincludedincostpergallonofnetcapacityandDenaliCommissionbenchmarkcosts).This is below the Denali Commission benchmarkcostrangeof$12.00 to $9.50 per gallon for 100,001 gallon to 200,000 galloncapacitytankfarms.The estimated cost of the electrical upgrade portion is$1,177,839 which equates to a unit cost of $4,097.55 per kW based on a totalinstalledcapacityof254kW(heat recovery upgrades,and design and construction administration costs not included in cost per KW of installed capacity and Denali Commission benchmark costs).This is above the Denali Commission benchmarkcostrangeof$3,500 to $2,900 per installed kW for 201kW to 400kW capacity power plants.

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 Community of Levelock: e Diesel power plant renovation. e Power distribution upgrades. e Generation heat recovery system upgrades. e Upgrades to existing bulk fuel storage and handling facilities. Participants in the project include the Levelock Village Council (Village)and Levelock Electric Cooperative (Utility). 1.1 Program Overview The AEA/REG 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 Community Development Quota program (CDQ),the State of Alaska,USDA,and loan financing. 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. e Each community will be requested to provide "in kind”contributions as available. Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering e Project may include local hire and construction trade training programs, subject to Denali Commission funding. e If the Denali Commission approves the business plan it will be circulated for signature and construction procurement will start. e Ineligible Projects:Funding is not available through AEA/REG 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/REG has several training programs available for communities which include:advance power plant operator,bulk fuel bookkeeper,bulk fuel operator,bulk fuel manager,hydro facilities operations, itinerant bulk fuel operator,power plant operator,and utility clerk.Contact Monica Moore,AEA/REG Training Program Manager,toll free at (888)-300- 8524 for more information. 1.2 |Community Description Levelock is located on the west bank of the Kvichak River,10 miles inland from Kvichak Bay.It lies 40 miles north of Naknek and 278 air miles southwest of Anchorage.It lies at approximately 59.12°North Latitude and -156.86°West Longitude (Sec.28,T012S,RO45W,Seward Meridian).Levelock is in a climatic transition zone;it is primarily maritime,although the continental climate also affects the weather.Average summer temperatures range from 30 to 66 degrees Fahrenheit;winter temperatures average from 4 to 30 degrees Fahrenheit.Annual rainfall is 26 inches,with 70 inches of snow.The population was estimated at 54 residents in 2005.Levelock Village is a federally recognized native village,and the community is in the Kvichak Recording District and the Lake and Peninsula Schoo!District (LPSD). 1.3 Site Investigation On Wednesday,September 22,2004,David Lockard of AEA/REG,John Dickerson of AE&E,and Vince Webster of LPSD traveled to Levelock to meet with local residents and tour the community.The purpose of the site visit was to observe the existing energy related infrastructure and assess the fuel and power needs of the community. Mr.Lockard,Mr.Dickerson,and Mr.Webster arrived in Levelock by plane at approximately 10:30 AM.Upon arrival they were met by Dan Salmon of the Igiugig Village Council and Iliamna Lake Contractors,who was acting as consultant to the Village.After a complete tour of the school mechanical building,power plant and all community bulk fuel facilities,a meeting with members of the Village was held. On January 19,2006,a conference call was held including Mr.Lockard of AEA/REG,Trevor Krupa of AE&E,and the Village regarding the status of the project.Mr.Krupa of AE&E made an additional site visit on Monday and Tuesday,January 23 and 24,2006,to obtain as-built information on the power plant,investigate a route for new electrical distribution line to a proposed fish 2 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering processing plant,and identify a route for new marine fill pipelines to the barge landing.While on site,Mr.Krupa met with council vice-president and school maintenance person Greg Andrew Jr. Prior to the field investigations,available information was obtained and analyzed, including aerial photographs,community profile,survey plats,PCE data,Corps of Engineers wetlands and flood information,and other relevant data.During the field investigations,the Utility electrical distribution system drawings,power generation operator logs,and community fuel use records were obtained. Additional information and input was obtained from the following individuals: e Howard Nelson,President (former),Levelock Village Council,287-3030 e George Wilson,Jr.,President,Levelock Village Council,287-3030 e Jennie (Mary)Apokedak,Administrator,Levelock Village Council,287-3030 e Marvis Dobkins,Manager,Levelock Electric Cooperative,287-3058 e Peter Apokedak,Jr.,Plant Operator,Levelock Electric Coop.,287-3058 e Brian Apokedak,Plant Operator,Levelock Electric Coop.,287-3058 e Vince Webster,Facilities &Maintenance Director,LPSD,246-4280 e Dave McClure,Bristol Bay Housing Authority,842-5956 e Kelly Leseman,ANTHC,729-3551 e Shaen Tarter,Yukon Fuel Co.,777-5576 e Mark Smith,Crowley Marine Services,278-4978 e Cameron Libby,Accounting Coordinator,Crowley Marine Services,777-5532 e Endil Moore,Crowley Marine Services,832-5505 e Pete LaPlante,Delta Western,246-6174 e Dan Salmon,Project Consultant,Igiugig Village Council,533-3211 e Kevin Degler,Alcan Electrical &Engineering,563-3787 1.4 Code Analysis &Deficiencies The following is a summary of existing power plant,and fuel system code analysis and deficiencies observed during the site investigations. Power Plant: e Antiquated /inefficient diesel gensets -expensive to maintain and operate. e Older automatic paralleling switchgear that does not respond properly to current community demand profile. Fuel Systems: e Improper Secondary Containment (Diking)-Many of the tanks are not within a proper liquid tight secondary containment system of adequate capacity as required by the Fire Code and EPA regulations. 3 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering e Improper Tank Foundations -Some tanks are installed on improper foundations,in violation of the Fire Code. e Improper Fencing -Tanks are currently accessible to the general public through unlock gates or missing sections of fence.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 Dispensing From Aboveground 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 Missing Signage -Required signage missing,including emergency switch and DEC spill information signs. e Improper Tank Labeling -Tanks are required to be labeled with product and capacity. 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 Levelock The concept design for all energy infrastructure projects have been prepared to meet current code and regulatory requirements,which include: e The 2003 Edition of the International Building Code (IBC). e The 2003 Edition of the International Fire Code (IFC)and currently adopted Alaska State Fire Marshal Fire and Safety Regulations. e The 2005 Edition of the National Electrical Code (NEC). e The 2002 Edition of the National Electrical Safety Code (NESC). 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. Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering 2.0 EXISTING FACILITIES The existing community energy infrastructure was evaluated to determine specific needs and deficiencies.The power plant,distribution system,heat recovery system and fuel storage were visually examined to determine suitability for re-use.The following paragraphs summarize findings for the community. 2.1 Power Plant The existing power plant and distribution system are owned and operated by the Utility,a subsidiary of the Village.The power plant building is located approximately 160'west of the school mechanical building.It is a 30'x40'pre- engineered steel frame structure with a concrete slab-on-grade foundation that was built approximately 20 years ago.The exterior siding and roofing is metal with fiberglass batt insulation.The building is partitioned to include an 11'x9' office area and a 19'x9'storage area.The building structure and concrete slab appear to be in good condition.The fiberglass insulation is oily and the metal siding and roofing are getting old. There are three diesel generators installed in the existing Utility power plant. Units #1 and #2 are John Deere model 6076A generators,each with a capacity of 130kW.Unit #3 is a John Deere model 6056T generator,with a capacity of 100kW.During the January,2006,site visit,it was noted that Unit #1 was out of service and disassembled with a damaged crank.Unit #1 is still currently out of service.Unit #2 had approximately 25,000 hours on it since its last major overhaul.Unit #3 had approximately 28,275 total engine hours.All units are near the end of their useful life. Engine cooling is with two remote radiators located outside on the east side of the power plant.All three generators are on a common cooling manifold with the two remote radiators.All of the existing engine cooling equipment appears to be original equipment and is near the end of its useful life. 2.2 Power Distribution Power generation is at 480V 3-phase.The existing manual paralleling switchgear includes a section for each of the three generators.The switchgear was originally installed in the 1980's and is due for replacement. Located adjacent to the power plant are three each 50kVA pole-mount,single- phase,480V transformers which step-up power to 7.2/12.47kV.Overhead electrical distribution is 12.47kV 3-phase throughout the core of the community with 7.2kV single-phase overhead extensions and 120/240V_single-phase overhead service drops. Alcan Electrical &Engineering performed maintenance and upgrade work on the distribution system in 2002.Alcan reported that with the exception of the existing switchgear,and existing pushmatics in meter loops,the distribution system is in good condition.Additionally,the plant operator reported no known problems with the distribution system with the exception of some fuses on top of the poles blowing due to nesting squirrels. Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering 2.3.Heat Recovery System The LPSD school facility is currently served by generation heat recovery from the Village power plant.Buried 3"copper supply and return pipelines run between a flat plate heat exchanger in the power plant and a brazed plate heat exchanger in the school mechanical building,approximately 180 feet away.Thermostatic valves are installed on each individual engine discharge line in the power plant cooling system,which is not standard on modern AEA/REG generation heat recovery systems.All of the existing heat recovery equipment appears to be original equipment and is near the end of its useful life. 2.4 Fuel Storage The existing fuel storage facilities are located at four separate sites.Tank farm numbers below correspond to the numbers assigned in the DOE database. Each individual 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 each tank farm: Village Diesel Storage -Tank Farm (#1).The Village owns three tanks located near the power plant.This facility receives and stores virtually all of the diesel fuel imported into the community.The fuel is used for community power generation,heavy equipment operation,and space heating requirements throughout the community.All three tanks are ex-military domed end heavy wall lapped steel tanks that had previously been installed belowground.Two of the tanks have a capacity of 50,000 gallons each and the third has a capacity of 25,000 gallons.The tanks all have heavy surface rust and poor paint condition. They are supported directly on the ground within a shallow lined earthen berm dike that does not appear to be liquid tight.The tanks are connected by a combination of threaded and welded black steel pipe.A centrifugal transfer pump is used for bulk transfers of diesel to the Village tanker truck for delivery throughout the community and for filling heavy equipment.The tanks are barge- filled by dragging the barge hose through town from the landing site,a distance of approximately 1,000 feet. School -Tank Farm (#2).The old school tank farm,formerly designated as DOE Tank Farm #2,consists of two vertical steel tanks with a total combined capacity of 31,500 gallons.These tanks are approximately 50 years old and were previously abandoned by the school.The old tanks were put back into service by the Village to provide extra fuel storage during the construction of the new airport.In September 2004,there was some residual fuel remaining in one of the tanks but the Village no longer uses them.The old tanks were taken out of service after all remaining fuel was removed.The new school tank farm is fully code compliant and consists of a single 12,000 gallon gross shell capacity horizontal skid mounted double wall tank in a lined timber tertiary containment dike.The tank is either truck-filled or filled directly from the barge hose.The fuel is used to provide space heat and emergency power generation for the school. Village Gasoline Storage -Tank Farm (#3 ).The Village owns three tanks located approximately 1,000 feet south of Tank Farm #1,near the bank of the 6 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Desiqn Report Alaska Energy and Engineering Kvichak River.This facility receives and stores virtually all of the gasoline imported into the community.The gasoline is used for community retail dispensing.All three gasoline bulk storage tanks are 10,000 gallon BIA style vertical steel tanks.They are supported on wood frame platforms within a shallow lined earthen berm dike that does not appear to be liquid tight.There is no manifold,fill or distribution piping.The gasoline is gravity transferred by fuel hose to a 1,000 gallon dispensing tank located approximately 200 feet away, near the abandoned community store.The bulk tanks are barge-filled. 3.0 COMMUNITY ENERGY DEMANDS 3.1 Current Power Demand Power plant generation and fuel use data was obtained from power plant operator's logs as well as from PCE reports and are included in Appendix D. The operator logs consist of three observations per day from June 2003,through December 2005.Between the months of September 2003,and April 2004, weekly peak recorded loads for the community ranged between 60kW and 100kW with weekly minimum recorded loads between 30kW and 60kW.The weekly recorded peak and recorded minimum loads for the same months one year later were 6OkKW to 90kW peak,and 20kW to 55kW minimum.From May through August the weekly peak recorded load range was between 35kW to 75kW with weekly minimum recorded loads ranging between 15kW and 40kW. The weekly recorded peak and recorded minimum loads for the same months one year later were 30kW to 6O0kW peak,and 5kW to 40kW minimum. According to PCE power sales data,the average annual load for the community during fiscal year 2003 was 50kW,,for fiscal year 2004 it was 47kW,and for fiscal year 2005 it was 45kW,all appear to correlate well with the operator log data. 3.2 Current Fuel Usage Fuel use records were obtained from the facility owners and fuel carriers for 2000 through 2005.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.

(3)Based on fuel use data from 2003 through 2005. 7 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering 3.3.Planned Community 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 following summarizes possible near-term future growth that may impact the community annual fuel consumption and power demand: e The Bristol Bay Housing Authority has plans to construct seven new HUD homes in Levelock for summer of 2006 -increase of 7,000 gallons in retail sales of diesel fuel for space heat,and increase of 1,400 gallons in retail sales of gasoline for new residents to fill new homes. e The Village commissioned Indian Valley International,Inc.to produce a study to determine the feasibility of a commercial fish and meat processing plant - increase of 5,500 gallons of diesel fuel at the power plant to meet added electric load,and increase of 6,000 gallons of diesel fuel in retail sales for plant heat.The anticipated peak electrical demand of the fish plant is 75kW. The proposed tank farm configuration provides capacity for the storage of either #1 or #2 diesel fuel.It is assumed that additional fuel consumption as a result of this facility would utilize #2 diesel. e ANTHC in conjunction with the Denali Commission is in the planning phase for a new Clinic -increase of 1,500 gallons in retail sales of diesel fuel for space heat. e The majority of the homes,school,and community buildings are on individual wells and septic tanks,ANTHC indicated there is no water or sewer project planned for the community. e The Village commissioned BRK Consulting to produce a business plan for a new boat dock,haul-out,and storage facility.The Village typically receives one fuel delivery per year in the spring.It was assumed that any increase in Village retail sales as a result of this project could be met with a second fuel delivery in the fall.It is assumed that additional fuel consumption as a result of this facility would utilize #2 diesel. e LPSD has tentative plans to renovate the school heating system.The renovations are anticipated to decrease fuel consumption at the school.No other upgrades or additions to the school are planned. e Alaska Department of Transportation completed an airport improvement and expansion project in 2003 and no additional airport modifications are planned. 3.4 Alternative Energy/Efficiency Improvements The existing Utility power plant generators are nearing the end of their useful service lives.The current manual switchgear in the power plant does not allow for automatic paralleling of generators.Careful sizing and selection of new generators in conjunction with the installation of new fully automatic paralleling switchgear and distribution improvements will likely result in an increase in community power generation fuel efficiency. Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering There is an existing heat recovery system installed in the Utility power plant that serves the school,located approximately 180 feet away.However,the power plant's existing engine cooling system is not designed to maximize generation heat recovery.According to LPSD maintenance superintendent Vince Webster the amount of heat received by the school has always been less than expected based on the school district's experience with generation heat recovery in other communities and has appeared to decrease on an annual basis based on increased school fuel consumption over time.The Levelock School has used an average of approximately 9,300 gallons of diesel annually for facility heating between 1999 and 2005.This is considerably higher than the average fuel consumption of other LPSD schools with properly functioning generation heat recovery systems.The high fuel use may be partially explained by the age,poor condition and additions/alterations to the original school heating system.During the September 2004,site visit it was observed that the school boiler was firing often even though it was a very mild day.This appears to verify the opinion of both school district and village personnel that the existing heat recovery system is not operating efficiently. Based on PCE fuel use records,it is estimated that the Utility power plant rejected the equivalent of approximately 5,700 gallons of heating fuel to the engine cooling system during heating season September 2003 through May 2004.Assuming that approximately 2/3 of the available heat should be able to be recovered and utilized,the utility should be able to provide recovered heat equivalent to approximately 4,000 gallons of heating fuel with a properly designed heat recovery system.Use of marine generators with wet manifolds could further increase the quantity of recovered heat. AIDEA published a Rural Alaska Energy Plan dated July 6,2004 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 Levelock is located within a class 3 wind regime and is not a viable candidate for a wind energy program using currently available technologies. There are no other known practical energy sources,such as solid fuel or natural gas,or hydroelectric currently available at Levelock.At this time it appears that new more efficient diesel generators,improved heat recovery,and possibly additional end-use conservation are the only viable fuel-saving technologies available for Levelock. 3.5 Fuel Storage Capacity Requirements The tank farm must be designed to meet the needs of the entire community with sufficient capacity to accommodate future growth.The following table compares the peak annual use of each product to the proposed net useable tank capacity for the new facility: Levelock Energy Infrastructure Upgrade Project Concept Design Report July 12,2006 Alaska Energy and Engineering ESTIMATED CONSUMPTION VERSUS PROPOSED CAPACITY Owner/Product Current Estimated Proposed |Proposed Peak Future Net Gross Annual Use |Average Capacity Capacity Annual Use Village #1 Diesel 79,900 (1)99,400 |108,000 (2)|120,000 (3) Village Gasoline 9,700 11,100 16,200 18,000 Proposed Total 124,200 138,000 (1)LPSD purchases ail fuel from LVC;includes peak School consumption. (2)Net capacity (90%of gross shell capacity) (3)The proposed tank farm configuration provides capacity for the storage of either #1 or #2 diesel fuel.It is assumed that additional summer time fuel consumption would utilize #2 diesel. LPSD purchases all fuel from the Village and stores it in its existing code- compliant 12,000 gallon gross capacity tank at the school.When calculating Village tank farm capacity requirements,it was assumed that the entire 10,700 gallon LPSD peak annual fuel use would be supplied from the Village tank farm. It is likely that the school tank will be filled during barge deliveries,thus providing some excess capacity in the tank farm for Village use.These quantities should be adequate to meet Village future growth requirements.Should future demand exceed this capacity for any product,the Village can receive two deliveries of fuel per year instead of the one. 4.0 PROPOSED ENERGY INFRASTRUCTURE PROJECT DESCRIPTIONS The following proposed project work is separated into six sections:Section 4.1, "Power Plant Renovation",describes proposed upgrades to the existing power plant;Section 4.2,"Distribution Upgrades",describes proposed current and future upgrades to the existing community electrical distribution system;Section 4.3,"Heat Recovery Upgrades",describes proposed upgrades to generation heat recovery and delivery systems;Section 4.4,"Tank Farm Upgrades", describes proposed upgrades to the Village tank farm;Section 4.5 "Demolition of Existing Tank Farm"describes the extend of demolition work to be done at the existing bulk fuel facilities as part of this project;and Section 4.6 "Proposed Operating Scenario"describes the proposed operational responsibilities at the finished facilities. 4.1 Power Plant Renovation The power system upgrade portion of the project consists of renovating the existing power plant building as well as installation of three new generators, automatic paralleling switchgear,engine coolant system,fire suppression system,automatic fill day tank system with used oil blending,ventilation,lighting, and new electrical station service. The nearby school complex is the largest single point heating demand and is already served by a heat recovery system.The proposed new bulk fuel facility will be located in close proximity to the existing power plant.Based on this,the existing power plant site is the most practical location for community power 10 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering generation.In addition,the existing 3-phase 7.2/12.47kV overhead power distribution system originates from this location and would not need to be modified if the power plant remains on this site. The existing steel structure will remain intact.All exterior siding,roofing,and insulation will be removed and replaced with metal clad foam panels.The interior partitions will be demolished and new partitions will be constructed as shown on attached drawing M7.The renovated power plant will also be provided with new ventilation,new station service electrical systems,and a fire alarm and suppression system. The new system will have two generators each sized to handle the community's normal peak load alone,and one generator sized to handle the nighttime and summer load.The automatic paralleling switchgear will allow any combination of generators to operate in parallel to meet community peak load plus the fish processing plant load.Based on the preliminary data available it is proposed that two each 95kW prime capacity and one each 64kW prime capacity generators be installed.These generators are available in a marine configuration with wet exhaust manifolds,which significantly increase the recoverable heat.Prior to final selection of generation equipment,power monitoring and recording equipment should be installed in the power plant to more accurately determine the electrical demand. New switchgear will be installed in the new power plant control room.There will be a total of 4 sections,one for each generator,and one for the 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 is achieved by matching the generator to the load.This style of switchgear has been used successfully on several recent Energy Authority projects.New meters will be installed to record the total power generated as well as station service power consumption. If the proposed future fish processing plant is constructed according to the preliminary design provided in the feasibility study,it will have a peak electrical load of approximately 75kW when under full production.Due to the fact that processing will occur during the normally low-demand summer season and the new plant will be capable of operating any combination of generators in parallel, there should be sufficient generation capacity available to power the processing plant.By providing a separate dedicated feeder,the power plant operators will be able to ensure that adequate generation capacity is on line prior to energizing the processing plant. The existing power plant engine cooling system will be completely replaced.The new system will consist of copper engine coolant supply and discharge piping manifolds,a single thermostatically controlled 3-way (Amot)valve,and dual remote radiators with variable speed control. A new 100 gallon day tank will be installed.It will be equipped with redundant overfill protection and alarm systems,a hand priming pump,and a totalizing meter.A used oil blender will also be installed to automatically mix used 11 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering lubricating oil with diesel fuel in the day tank.New buried welded steel distribution piping will be installed to the bulk tanks in the new tank farm.All new welded steel fuel and lube oil piping will be installed in the power plant. 4.2.Power Distribution Upgrades As previously discussed there are no major problems with the existing community overhead power distribution system.However,the current distribution system would not be adequate to support the proposed future seafood processing plant.If constructed,the seafood plant will have large refrigeration compressors with high-inductive startup loads that can cause brownouts and/or power outages in the community if operated without adequate online spinning reserves.In order to isolate the seafood plant from the community power supply it is proposed to provide three feeders with separate circuit breakers and metering in the new power plant switchgear distribution section -one for power plant station service,one for the Village distribution,and one for a future dedicated 3 phase,480 volt feeder to the proposed fish processing plant (see Sheet M1). 4.3.Heat Recovery System Upgrades All new generation heat recovery equipment including brazed plate heat exchangers,pumps,instrumentation,energy meter,thermostatic valve,and arctic piping will be installed to serve the school.The arctic piping will be welded steel carrier pipes with polyurethane insulation and an HDPE jacket and will be installed below grade. 4.4 Tank Farm Upgrades All of the existing tanks,associated piping systems and equipment are in marginal condition and would not be cost effective to renovate.Therefore it is proposed to replace all existing fuel storage facilities with a new Village tank farm that will provide room for storage of all diesel fuel required for Village space heating,heavy equipment operation,electrical generation,and bulk transfer operations,as well as provide gasoline for retail sales.The design provides for a new lined timber wall dike to contain all of the bulk storage and dispensing tanks. The dike will contain four diesel fuel bulk storage tanks of 30,000 gallons capacity each,one gasoline bulk storage tank of 12,000 gallons capacity,and one single product 6,000 gallon double wall fired rated gasoline dispensing tank. The diesel fuel bulk transfer area will consist of a concrete pad sloping into the tank farm secondary containment for filling fuel trucks and portable tanks.A single product gasoline dispenser will be provided for retail sales.Security fencing will enclose the dike,bulk transfer area,and dispenser.All work is shown on attached drawing M2. The International Fire Code and E.P.A.regulations require fuel tanks to be installed within a secondary containment structure that is capable of holding the contents of the largest tank plus sufficient freeboard to hold accumulated precipitation.The Lake and Peninsula Borough Coastal Management Plan requires the secondary containment to be capable of containing 115%of the capacity of the largest tank plus 12"of freeboard for precipitation.Based upon 12 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering local soils conditions and the absence of locally available gravel,a heavy timber wall dike with a membrane liner was determined to be the most practical means of providing secondary containment. The Village tank farm secondary containment will be sized to contain 115%of the facility storage capacity plus 12”of freeboard for precipitation.The timber wall dike will provide secondary containment for the 30,000 gallon diesel fuel bulk tanks and the 12,000 gallon gasoline bulk tank.The 6,000 gallon tank will be a fire rated double wall tank with integral secondary containment.The dike will provide tertiary containment for the fire rated double wall tank.The timber wall dike will be lined with a membrane liner compatible with both diesel fuel and gasoline.A non-woven geotextile fabric will be installed above and below the liner to minimize the risk of puncture and damage and an 8”deep layer of gravel cover will be placed over the liner.Sheet metal covers will be installed over the liner and non-woven geotextile on the inside of the vertical walls.A drainage sump will be provided for storm water removal via a siphon hose or portable pump. The new Village tank farm diesel and gasoline bulk storage tanks will be a shop built single wall horizontal welded steel tank built and labeled in accordance with UL 142 and equipped with steel saddle and skid foundations.The new gasoline dispensing tank is required to be a two-hour fire rated tank due to its proximity to property lines and road right-of-ways and will be built and labeled in accordance with UL 2085.This type of tank is only available in a horizontal double wall configuration and will be equipped with an overfill protection device.All tanks will be equipped with level gauges,pressure/vacuum whistle vents,emergency vents,manholes,and water draws.The new single wall bulk storage tanks will be equipped with a flanged tank bottom connection.All tank skids will be placed on concrete footings sized to limit soil bearing pressure to 1,500 pounds per square foot. All 3”piping within dikes will be schedule 40 pre-primed and painted steel.All other above grade piping will be schedule 80 pre-primed and painted steel.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 buildings and secured with steel 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. One 3”diameter diesel fuel pipeline and one 2”diameter gasoline fill pipeline will be routed together below grade 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).Separate manifold piping will be provided for diesel 13 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering fuel and gasoline.Manifold piping will be connected to the fill pipelines with isolation and check valves. A bulk fuel transfer area with secondary containment will be provided at the Village tank farm to allow portable tanks and tanker trucks to be filled with diesel fuel from the Village bulk storage tanks.The bulk transfer equipment will include a centrifugal pump for diesel,pipeline filter,custody transfer meter,hose,bulk transfer nozzle,and static grounding line. A service station style single product gasoline dispenser will be installed in a security enclosure near the Village tank farm.A key-access type inventory control system will be installed to allow local residents access to gasoline without requiring a Village employee to oversee sales.This system has separate keysforeachparty(family or business).A key is required to activate the dispensing system.Adjacent to each key switch is a mechanical totalizing meter that maintains a permanent total of gasoline dispensed by each party. A 6'tall chain link fence with a 1'high barbed wire top will enclose the Villagetankfarmdikeandbulktransferarea.Three 3'wide personnel access gates andtwo12'wide vehicle access gate will be provided into the fenced enclosure.The gasoline dispenser will be installed within a post structure with concrete floorslab,metal roof,and full-height chain link fence walls.All valves will be providedwithlockablehandlestopreventtheftandvandalism.Pump controls will be installed within fenced security areas or buildings.Area lighting will be providedatthedispensers,pump controls,and dike for security and spill detection and to enhance winter operation. 4.5 Demolition of Existing Village Tank Farms The scope of this project will also include removal from service of all existing Village tanks.All existing 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 State Fire Marshal and EPA standards and procedures. 4.6 Proposed Operating Scenario The Village is currently operating the existing tank farm and is currently providing bulk fuel transfers and gasoline retail fuel sales,and will continue with these responsibilities with the new tank farm facilities.The Utility is currently operating the existing power plant,and will continue to operate the renovated power plant. Management responsibilities of the new tank farm include:maintenance and operation of all tanks,pumps,and piping systems:removal of storm water from the dikes;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. 5.0 SITE SELECTION &CONTROL The majority of all work proposed for the BFU and RPSU project will be restricted to the "Tank Farm/Power Plant Site"and "Marine Header Site”. 14 Levelock Energy infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering 5.1 Tank Farm/Power Plant Site Consolidation of all Village bulk fuel storage,bulk transfers,and retail sales operation will occur at the new Village tank farm site located adjacent to the existing Utility power plant and existing Village tank farm. A new tank farm site was initially selected as shown in a site visit trip report dated September 30,2004.During a January 19,2006,teleconference,the Village council members expressed concern with flooding from snow melt at the proposed site,requested the tank farm facility be relocated as shown on M1. Storage containers with a roof structure that will need to be relocated currently occupy the tank farm site.The site is also currently used as a storage area by the Utility. The proposed tank farm and power plant sites are well above the level of the Kvichak River,and there is no known flooding hazard at the site.According to the Corps of Engineers,Alaska Communities Flood Hazard Data,June 2000, "the community is located on a high bluff well above normal high water”. Geotechnical data on the proposed tank farm site does not exist,but from geotechnical report prepared in conjunction with the airport project,soils at the project site are expected to be 0”to 8”organic material,8”to 20”moist silt,20”to 30”moist sandy silts,30”to 130°of sand.Of the 53 samples taken at the airport, all exhibited similar soil profiles,and no or very sparse gravel was encountered. Levelock area is mapped as underlain by isolated masses of permafrost and is usually found either at considerable depth or near the surface as thin lenses. Community members reported no known spills have occurred at the site,but a geotechnical investigation to include a search for hydrocarbons should be perform early on in the design phase. A topographic survey to locate existing infrastructure and property boundaries as well as to establish elevation bench marks,provide surface contour elevation data,and to locate the propose marine fill pipeline route should also be performed early in the design phase. 5.2 Marine Header Site The existing barge landing site is located on LPSD school site and the marine header was located close to the existing barge landing site.Council members stated the header should remain at least 100'from the river to avoid damage from ice jams.Barge captains were consulted in regards to the marine header location and stated near the existing barge landing was the preferred location. The fill pipeline route from the marine header to the tank farm was selected to remain clear of water wells as is required by the Fire Code. 5.3 Site Control A Certificate to Plat was issued by Pacific Northwest Title of Alaska effective February 1,2006.A copy of the Certificate to Plat is included in Appendix C. The proposed tank farm,dispenser,and bulk transfer area are located on Lot 2, Block 9A,U.S.Survey 4877.The existing power plant is located on Lot 1,Block 9A U.S.Survey 4877.The proposed tank farm,as well as the existing power 15 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering plant is located on lots with interests currently vested in the Levelock Village Council. The proposed marine header and fill pipeline are located on U.S.Survey 914, which is the school lot.The Certificate to Plat indicated interest in the LPSD Levelock School Site is currently vested in the State of Alaska,Department of Natural Resources.An existing deed transferring ownership from the State was recorded in the wrong recording district,the Bristol Bay Recording District.To be able to establish site control,a certified copy of the original deed will need to be recorded in the Kvichak Recording District. 6.0 PERMITTING AND SPILL RESPONSE The proposed new tank farm and power plant upgrades will be subject to regulations of both State and Federal agencies including the Alaska Coastal Management Program,the Lake and Peninsula Borough,the Division of Fire Prevention,the U.S.Environmental Protection Agency,and the U.S.Coast Guard.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. 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 determines whether there is a 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 helps to 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.The need for a wetlands permit will be investigated further with the Corps of Engineers early in the permitting phase. A Development Permit will be required from the Lake and Peninsula Borough to construct the consolidated tank farm.This permit usually requires a public hearing and waiting period.The process is expected to take approximately 3 months and should begin in December to ensure completion in time for spring construction.. 6.2 Fire Code A Plan Review permit from the State Fire Marshal is required for the fuel and power plant portions of the project.Final stamped design drawings will be submitted to the Fire Marshal for review prior to construction.Plans will be reviewed for conformance with the International Fire Code and related codes including the International Building Code and the National Electrical Code.The review process can take anywhere between 3 weeks to 6 months. 16 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering 6.3 Spill Response Because the new Village tank farm will have oil storage tanks in excess of 1,320 gallons,and because it 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 also be required to have a Spill Prevention Control and Countermeasures (SPCC)plan.This plan will address all tanks of 55 gallon or greater capacity.The required Coast Guard and EPA plans will be prepared upon completion of facility construction as a coordinated package. The existing school facility has an SPCC plan.This should be reviewed as part of this project and revised as required to meet current EPA regulation and policy. Spill response gear including absorbent material and protective safety gear will be purchased and left on-site upon project completion.Options for utilizing an existing storage tank for oil spill contingency will be investigated during final design. 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 communities and funding agencies.The highly technical nature of power generation and distribution 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 power generation and distribution systems.Skilled craftsmen with appropriate certifications must perform all specialty work,such as pipe welding and electrical installation.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 Village for information regarding the availability of specialty skilled labor in Levelock.The table on the following page summarizes the results: 17 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering Skilled Trades Number Available Laborer 4 Truck Driver 4 Heavy Equipment Operator 4 Heavy Equipment Mechanic 1 Welder Helper 1 Certified Welder 0 Apprentice Electrician 2 Journeyman Electrician 0 It appears that at a minimum a project superintendent,a pipe welder/mechanical foreman,a journeyman carpenter,and a journeyman electrician will need to be brought into Levelock for this project. 7.2 Local Equipment The Village provided the following inventory of locally available heavy equipment: Unit Make/Model #Year/Condition Dump Truck Dodge Not running Dozer with Backhoe John Deere 450C It runs Loader with Forks &Bucket John Deere 544C It runs Crane Paco Pett Bone 70 Good,it runs All the equipment shown above belongs to the Village.Additional heavy equipment needed include a large loader,and a small skid steer (Bobcat or similar)with various attachments.These could be leased and mobilized to the site for this project.Prior to the start of construction an experienced fleet service mechanic will need to be sent to Levelock to go through the equipment with the local mechanics to ensure that it is all in proper operating condition. 7.3 Material Sources There is no borrow source for gravel within the community.Select gravel for topping the dike liner and for making concrete must be barged into the community from Naknek.A Village owned borrow source for sand/silts is located near the airport.Additionally,the Village indicated the old airport runway has been deeded to the Village,and can be made available to the project for fill material. 18 Levelock Energy Infrastructure Upgrade Project July 12,2006 Concept Design Report Alaska Energy and Engineering 8.0 SCHEDULE Northland Services indicated it does not service Levelock.This makes it necessary for Northland to haul the freight from Seattle or Anchorage into Dillingham and Crowley Marine to take the freight from Dillingham to Levelock. The cost associated with this service is very high at approximately $0.41 per pound for cargo and $58.00 per cubic foot for tanks.A chartered barge out of south-central Alaska may be able to deliver the tanks for less than the tariff rates.Additionally,Crowley Marine indicated they deliver fuel into Levelock in June,and again in August or September,but these fuel barges do not haul freight.The Construction Manager should investigate freight options during the design phase of the project.

LEVELOCK.AIRPORT RELOCATION PROJECT |! LOCATION |: PROJECT NO.51814 LOCATION MAP SCALE:3/4°=1mile DATA:U.S.G.S. LEVELOCK AIRPORT GEOTECHNICAL INVESTIGATION INTRODUCTION On July 12,1996,the Central Region Materials Section received a request from John Wahl,Project Manager,Aviation Design,for a materials investigation for the planned relocation of the State airport at Levelock.The Central Region geotechnical staff conducted a geotechnical field investigation for the new Levelock Airport from December 5 to 18,1996,under the supervision of Tom Ottley,Engineering Geologist,with the assistance of Jeff Nelson,Driller. We understand the proposed project includes: A new runway embankment 36m x 1144m with 18m x 1000m runway surfacing; A taxiway 24m x 57 m; An Apron area 103.5 mx 115 m; An Access Road 7.5 m x 900 m; An Access Trail 5m x 745 m; A Medium Intensity Light System including power line extension and relocation of power line in runway approach; 7.Taxiway Lights;and 8.A 7mx 14m Snow Removal Equipment Storage Building.AARWNoA Test Pit Location Plan sheet,Test Pit Logs and Preconstruction Sample Summary sheets are attached. LOCATION Levelock is located on the west bank of the Kvichak River,16 kilometers upstream from Kvichak Bay,64 kilometers north of Naknek and 445 kilometers southwest of Anchorage.It is located near the Alagnak Wild and Scenic River Corridor at approximately 59°7'N,156°51'W Sec.28,T12S,R45W,Seward Meridian.The Community area encompasses 4500 hectares of land and 800 hectares of water. Levelock is accessible by air and water.In the winter,travelers use trails to surrounding villages. The State owns a 579 meter lighted gravel runway and 549 meter crosswind runway in Levelock. Scheduled and charter flights are available.Bulk 'Boods are delivered by barge to a 33.5 meterdockandbeachunloadingarea. GENERAL GEOLOGY AND TOPOGRAPHY Levelock is located within the Nushagak Geographic District.The Nushagak District is an area of about 2.2 million hectares in southwestern Alaska that extends northward from Nushagak and Kvichak Bays for a distance of approximately 160 kilometers.The district is comprised of three geographic units that are drained by the Nushagak and Kvichak Rivers.The first geographic unit is the Tikchik Mountains,which form the eastern part of a large mountainous province that constitutes the western part of this district.The Tikchik Mountains form a rugged highland isolated from the main mountain ranges of southern Alaska and bordered on their east side by a system of 12 more or less parallel deep glacial lakes,which now occupy bedrock basins.The second unit is the Nushagak Hills,a group of low rounded hills that form the northeastern part of the district.The third unit is the lowland of the Nushagak and Kvichak Rivers that comprise the eastern and southern part of the district. The Levelock Airport Project is located in the lowland unit.It is partially bounded by the Nushagak Bay to the south,the Tikchik Mountains to the west,and the Nushagak Hills to the north.The soil deposits in this area were formed during the Wisconsin glacial epoch and consist of morainal,glaciofluvial,fluvial,and eolian deposits.Glaciers formerly covered the entire area. The topography is mostly rolling,with many irregular moraine knolls and ridges separated by muskegs.A thick layer of wind-deposited soil mantles the uplands.This soil is a mixture of silt blown from unvegetated flood plains and hills adjacent to the melting glaciers and volcanic ash from the Aleutian Range to the east and south. PERMAFROST The Levelock area is mapped as underlain by isolated masses of permafrost;predominantly in fine-grained deposits.Permafrost in this region is usually found either at a considerable depth as relict permafrost or near the surface as thin lenses of small extent where ground insulation is _high.No permafrost was encountered during this field investigation. CLIMATOLOGY The climate at Levelock is transitional between sub-polar marine and the colder,continental climate of interior Alaska.The temperature inland at Levelock is warmer in summer and colder in winter than along the Bristol Bay coast.Low barometric pressure centers with accompanying storms from the Aleutian Islands sweep up Bristol Bay and across this area from early July through December.During the early part of the year Levelock is more under the influence of cold dry air associated with high-pressure areas coming in from the north. Average summer temperatures range from -2°C to 19°C;winter temperatures average from -16°C to -2°C.Annual rainfall is 650 mm,with 1800 mm of snow.Fog and low clouds are common during the summer.The River is ice-free from June through mid-November.For current,site- specific weather and climate data contact the National Oceanic and Atmospheric Administration at 6930 Sand Lake Road,Anchorage Alaska,or the National Weather Service web page at http://www.alaska.net/ nwsar/. FIELD INVESTIGATION During the field investigation the field crew excavated 30 test pits with a rented John Deere 450- C tractor with backhoe.53 field samples were taken directly from the sidewalls of the test pits at various depths.The samples were tested at the Central Region Materials Laboratory for;1) gradation,2)soil classification,3)moisture content,4)organic content,and 5)moisture-density relationship. The field crew established two base lines (approx.centerline of the proposed runways)using a Brunton compass and cloth tape.The crew referenced test pit locations from these lines and with a Garmin 45 hand-held GPS unit. RUNWAY ALIGNMENTS The locations for main runway,crosswind runway,apron,taxiway and access roads were moved after the field investigation so test pits do not consistently lie within the proposed facilities as shown on the attached Test Pit Location Plan sheet.However,the test pits are spaced widely throughout the planned airport property and do characterize the foundation soils. The field crew excavated eighteen test pits along the proposed runway alignments (T.P.'s 1-12 and 24-29).Test Pit depths ranged from 2.0 to 4.1 meters.The generalized soil profile consists of 0.3 to 1.0 meter of organics and organic silts,over 0.2 to 1.1 meters of silt and sandy silt (with volcanic ash),over sand and silty sand to the maximum tested depth. The surficial organics are typically flat lying to hummocky with occasional depressions up to 2-3 meters in depth.The underlying organic silt and silty organic soil is typically moist to wet and contains occasional thin volcanic ash lenses.The silt layer contains clay and volcanic ash and is moist to wet.When disturbed this layer may flow,resulting in difficult handling.These "overburden”soils typically overlie sand and silty sand observed at depths of 0.4 to 1.7 meters. The sand and silty sand material appears dry to moist and loose.A water table was encountered in 3 of the 18 test pits.The sand and silty sand foundation material contained 0-22%P0.075 and 0.5-2.2%organic.The moisture content ranged between 4.7%and 7.6%(9 samples). PROPOSED RUNWAY SIDE BORROW Twelve test pits were advanced adjacent to the proposed main runway alignment (see T.P.'s 13- 96 thru 23-96 and 30-96)in search of potential borrow material.The soils typically consisted of 0.3 to 1.5 meters of organic,organic silt and silt overburden soils over sand and silty sand soils to the maximum test pit depth of 4.3 meters.No water table was encountered in any of the 12 test pits. The overburden soils were typically moist to wet where thawed.Seasonal frost was typically 0.5 m deep.These soils also contain some volcanic ash.The underlying sand and silty sand is typically loose and dry.Where tested,these granular soils contain 1-8%silt (P0.075mm)with moisture content of 4.3-6.8%.Three moisture-density tests run on a combination of the sand and silty sand material indicated an optimum moisture of 13-14.5%and a maximum dry density of1690-1710 kg/m', GENERAL CONCLUSIONS AND SITE CHARACTERISTICS "1,The materials observed in the proposed side borrow area consist of loose sand and silty sand with a P0.075 of 1-8%.The construction contractor should choose equipment capable of operating on this type of material. 2.Compaction and handling difficulties could arise when working with the clean sands that are prevalent in the vicinity of the new airport.The addition of fines (silt and fine sand)and careful moisture control may be necessary to achieve a well-compacted,stable embankment. 3.Fines containing volcanic ash should not be used as a source of blend material.(Volcanic ash was encountered within and immediately below the organic material on airport property). Blend fines for the crushed aggregate surface course should be obtained from below the organic and organic silt soils. 4,When any moist to wet silt layers containing clay and volcanic ash are disturbed,the material may flow,resulting in difficult handling. 5.No suitable granular materials for the crushed aggregate surface course were found in the vicinity of Levelock. 6.The hummocky terrain at the proposed airport site contains many depressions up to 2-3 meters in depth by 2-3 meters in width.Due to the irregular terrain,careful field survey and cross-sectioning should be done prior to construction,to establish an accurate baseline for quantity measurements.

APPENDIX F MEETING SUMMARY NOTES Alaska Industrial Development and Export Authority 'Alaska Energy Authority February 17,2005 Howard Nelson,President Levelock Village Council P.O.Box 70 Levelock,AK 99625DearMr.Nelson: The Alaska Energy Authority (AEA)began work on a conceptual design report for Levelock energy projects in the fall of 2004.The scope of the report includes an assessment of and recommendations for upgrading the community's fuel storage,power generation and electrical distribution facilities.The design engineer,John Dickerson of Alaska Energy and Engineering (AE&E)and |met with community representatives and residents on September 22,2004,to discuss the community's energy needs.I have attached John's trip report for your review. |recently found population data on the Department of Labor website which indicate that Levelock's population has dropped from 122 in 2000 to 57 in 2004.This is important because the Denali Commission has a policy that addresses population change:the April 2004InvestmentPolicy.|have attached a copy for your reference. Please send me your best estimate of population change in Levelock over the next ten years,as well as the basis for your estimate.Any information you can provide on other factors that may impact energy use,such as a proposed fish processing plant,would also be helpful. During our site visit,we discussed the possibility of a significant local cash match for the energy projects requested by the Council.The Council members present said that the Community Development Quota program may have funds available to Levelock for such projects.If the population data are accurate,|anticipate that a significant match will be necessary to obtain approval and funding of the proposed projects from the Denali Commission. |look forward to working with you and other Council members on this project.

General Policy Commission investments are directed by federal law,by the Commission's Guiding Principles and by specific allocation decisions made by the Commission. Infrastructure needs of rural Alaska are enormous compared to available funding, thus,it is imperative that each dollar be invested in a way that will maximize the sustainable long term benefits to Alaskans. The Commission will promote investment in infrastructure where the promise of sustainability (facility and services)can reasonably be demonstrated both now and in the future.Infrastructure sustainability can be enhanced by adapting available technology and appropriately sizing facilities to meet the particular needs and circumstances of communities. Factors which will influence investment decisions: A.Imminent environmental threats Facilities will be placed so as to be protected from imminent environmental threats such as flooding and erosion.Long term investments generally will not be made in areas that are subject to imminent environmental threats. Denali Commission Investment Policy April 2004 B.Priority to be placed on needs of existing communities | The Commission will give priority to the critical infrastructure needs of existing communities before considering proposals to create new communities unless there is a congressionally directed relocation of an existing community. .Regional support The Commission recognizes that borough and local governments promote equity among Alaskans and that the existence of a state-chartered government increases the probability that basic infrastructure and services provided with Denali Commission funds will be sustained over the long term.The Commission also - recognizes that other regional organizations share both responsibility and capacity to contribute to sustainability.Consistency with a regionally approved plan is a factor lending strength to investing in a particular project.) Proximity/access to existing services and/or facilities in determining the need for a new facility,a careful evaluation of existing access to services or facilities will be performed.Where the needs of two or more communities in close proximity to one another can be adequately and more costeffectivelyservedbyasinglefacility,that option will be selected over separatefacilitiesforeachcommunity.Investments will be made where critical unmet needs| are demonstrated. Renovation versus new construction ° Where existing facilities can be renovated or expanded to adequately meet community needs at significantly lower life-cycle costs than new construction,that option will be favored. Population trends Infrastructure will be sized to meet needs that can reasonably be projected over the design life of the project.If population is increasing,appropriate excess capacity will be provided to accommodate growth.Decreasing population may result in a smaller facility then the current population would dictate.For communities with populations declining 20%or greater over a 10 year census period and where there is indication such trends will continue,special attention will be given to appropriate design and sizing of facilities. .Affordability The Commission will evaluate proponents'capacities to afford the life-cycle costs associated with sustaining proposed services and/or facilities,either through user fees,industry support,government transfer payments or grants from private entities. .Per capita investment While there are many factors which may explain extreme variations in per capita investment in communities,the Commission will compile and review this data to ensure that there is reasonable equity in the distribution of funds across all rural Alaska communities. Denali Commission Investment Policy :April 2004 1.Unit cost Unit cost of construction varies widely across the state for a number of reasons including the technology employed and/or designs utilized.High unit cost tends to work counter to project sustainability.Some of the variables impacting unit cost (project location,soil conditions,etc.)are not controllable,but many others are.The Commission will make every reasonable effort to control unit cost by working with award recipients through its Partners to ensure that the most appropriate technology and designs are applied. -J.Good faith The long term sustainability of Commission investments is highly dependent on the good faith of the recipients of those investments.In evaluating potential investments the Commission will give priority to advocates who have historically demonstrated good faith in making and keeping financial commitments.Previous demonstrations of bad faith,particularly with previous state or federal investments or failure to pay taxes,may preclude additional investments. Implementation The Commission will consider all available information regarding each of the factors identified above and any other relevant information in making investment decisions. In cases where sustainability of an investment is questionable,the Commission, either directly or through its Partners,will work with project proponents to attempt to find workable solutions.It will be incumbent on requestors to provide pertinent information that is not otherwise available and to actively engage in the effort to develop workable solutions.Solutions may involve smaller scale or mobile facilities and may include multi-community or regional management approaches.If no workable sustainable solution is apparent,the Commission or its Partners may suggest alternative means to access critical services. Decisions regarding questionable investments will be made by the Commission'sChiefofStaff.Any decisions made relative to this policy may be appealed first to the Federal Co-Chair and ultimately to the full Commission.

We arrived in Levelock by plane at approximately 10:30 AM.Upon arrival we were met by Dan Salmon of the Igiugig Village Council and lliamna Lake Contractors,who is acting as consultant to the Levelock Village Council (LVC). After a complete tour of the school mechanical building,power plant and all community bulk fuel facilities,we met with members of the LVC.

Power plant generation and fuel use data was obtained from power plant operator's logs as well as from PCE reports (see attachments).The operator logs consist of three discreet observations per day from August 2003 through August, 2004.The log entries were typically recorded at approximately 8:30AM,Noon, and 6:30PM.Between the months of September,2003 and April,2004,weekly peak recorded loads for the community ranged between 60kW and 100kW with weekly minimum recorded loads between 30kW and 60kW.From May through August the weekly peak recorded load range was between 35kW to 75kW with weekly minimum recorded loads ranging between 15kW and 40kW.According to PCE power sales data,the average annual load for the community during fiscal year 2003 was SOkW,which would appear to correlate well with the operator log data. There are a total of three generators installed in the power plant.Units #1 and #2 are John Deere model 6076A generators,each with a capacity of 130kW.Unit #1 has approximately 28,000 hours since its last major overhaul.Unit #2 had a complete overhaul in 1998 and now has approximately 18,000 hours.Unit #3 is a 100kW backup unit with approximately 28,000 total engine hours.Engine cooling is with two remote radiators located outside behind the power plant. Power generation is at 480V 3-phase with a step-up transformer bank for the 7.2kV/12.47kV distribution.The manual paralleling switchgear includes a section for each of the three generators. Page 2 of 6 Levelock Power and Fuel Facilities 9/22/04 Site Investigation Trip Report Generation Heat Recovery System: There is an existing heat recovery system installed in the Village power plant that serves the school,located approximately than 180'away.However,the power plant's existing engine cooling system is not designed to maximize generation heat recovery.According to LPSD maintenance superintendent Vince Webster the amount of heat received by the school has always been less than expected based on the school district's experience with generation heat recovery in other communities and has appeared to decrease on an annual basis based on increased school fuel consumption over time.The Levelock Schoo!has used an average of approximately 8,600 gallons of diesel annually for facility heating between 1999 and 2003.This is considerably higher than the average fuel consumption of other LPSD schools with properly functioning generation heat recovery systems.The high fuel use may be partially explained by the age,poor condition and additions/alterations to the original school heating system.. However it also appears to verify the opinion of both school district and village personnel that the existing heat recovery system is not operating effeciently. Based on PCE fuel use records,it is estimated that the Village power plant rejected approximately 5,700 equivalent gallons of heating fuel to the engine. cooling system during this past heating season (September 2003 through May 2004).Assuming an additional 25%reduction due to parasitic losses,the school's annual fuel use could be reduced by as much as 4,300 gallons with the installation of properly designed engine cooling and heat recovery systems in the Village power plant. Existing Fuel Storage Facilities: The existing fuel storage facilities are located at four separate sites.Tank farm numbers below correspond to the numbers assigned in the DOE database.Each individual 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 each tank farm: e Village Diesel Storage -Tank Farm (#1).The Village owns three tanks located near the power plant.This facility receives and stores virtually all of the diesel fuel imported into the community.The fuel is used for community power generation,heavy equipment operation,and space heating requirements throughout the community.All three tanks are ex-military domed end heavy wall lapped steel tanks that had previously been installed below ground.Two of the tanks have a capacity of 50,000 gallons each and the third has a capacity of 25,000 gallons.The tanks all have heavy surface rust and poor paint condition.They are supported directly on the ground within a shallow lined earthen berm dike that does not appear to be liquid tight.The tanks are connected by a combination of threaded and welded black steel pipe.A centrifugal transfer pump is used for bulk transfers of diesel to the Village tanker truck for delivery throughout the community and for filling heavy equipment.The tanks are barge-filled by dragging the barge Page 3 of 6 Levelock Power and Fuel Facilities 9/22/04 Site Investigation Trip Report hose through town from the landing site,a distance of approximately 1,000 feet. e School -Tank Farm (#2).The old school tank farm,formerly designated as DOE Tank Farm #2,consists of two vertical steel tanks with a total combined capacity of 31,500 gallons.These tanks are approximately 50 years old and - were previously abandoned by the school.The old tanks were put back into service by the village to provide extra fuel storage during the construction of the new airport.There is still some residual fuel remaining in one of the tanks but they are no longer needed by the village.The old tanks are slated to be taken out of service again after all remaining fuel is removed.The new school tank farm is fully code compliant and consists of a single 12,000 - gallon gross shell capacity horizontal skid mounted double wall tank in a lined timber tertiary containment dike.The tank is either truck-filled or filled directly from the barge hose.The fuel is used to provide space heat and emergency power generation for the school. e Village Gasoline Storage -Tank Farm (#3 ).The Village owns three tanks located approximately 1,000 feet south of tank farm #1,near the bank of the Kvichak River.This facility receives and stores virtually all of 'the gasoline imported into the community.The gasoline is used for community retail dispensing.All three gasoline bulk storage tanks are 10,000 gallon BIA style vertical.steel tanks.They are supported on wood frame platforms within a shallow lined earthen berm dike that does not appear to be liquid tight.There is no manifold,fill or distribution piping.The gasoline is gravity transferred by fuel hose to a 1,000 gallon dispensing tank located approximately 200 feet away,near the abandoned community store.The bulk tanks are barge-filled. Current Fuel Consumption: Fuel use records were obtained from the facility owners and fuel carriers for 2000.through 2003.The following table summarizes average consumption andexistingstoragecapacity.All capacities are in gallons.Net capacity is calculatedas90%of the tank gross (shell)capacity.

Page 4 of 6 Levelock Power and Fuel Facilities 9/22/04 Site Investigation Trip Report Local Population Trends: The State of Alaska Online Community Database shows that the population of Levelock has fallen from 122 residents in the year 2000 to a current State Demographer estimate of 71.This population trend raises concerns about the long.term viability of the community if it were to continue.This issue was discussed at the community meeting.Howard Nelson mentioned that the population estimate of 122 in the year 2000 appeared to be excessive,either due to a miscount or to a temporary influx of people at that time.He did agree that the population has dropped over the past several years but attributed the decline to a combination of the depressed salmon fishery,lack of adequate housing,and several recent deaths in the community.The consensus of council members present was that the population of Levelock has stabilized and may now be increasing again.Six new HUD homes scheduled for construction in 2006 will likely encourage a further increase in population.According to Vince Webster the school population has been relatively stable over the past few years,with a current enrollment of 17 students,down from an enrollment of 22 in the year 2000. Planned Projects and Infrastructure Improvements: The Bristol Bay Housing Authority is planning for the construction of six HUD. homes in Levelock for 2006. The Village council recently commissioned Indian Valley International,Inc.to produce a study to determine the feasibility of a commercial fish and meat processing plant in Levelock.The study was funded in part with Mini-Grant Assistance funds through the DCED and the Denali Commission.Due to its status as a CDQ qualified community,the Village Council has also received $200,000 from the Bristol Bay Economic Development Corporation in matching funds for the design and construction of a fish plant.If constructed according to the preliminary design provided in the study,the plant would consume approximately 75kW of electricity when under full production.Due to the full paralleling capability of the power plant switchgear and the fact that processing will occur during the normally low-demand summer season,sufficient generation capacity should be available to power the processing plant.However,care will need to be taken in the design of the processing plant electrical system. Community brown-outs could occur during hard starts of large demand electrical equipment such as refrigeration compressors.Solid state soft start technology should be used in the starting circuitry of all electric motors of 5HP and greater to minimize the effect on the community power grid.Provisions could also be made in the power plant for the future installation of a switchgear feeder section dedicated to the processing plant.This would allow for additional isolation of the processing plant from the village power grid. In conjunction with the fish plant,the Village Council is also actively pursuing funding for design and construction of a freight dock,boat ramp and boat storage facility on the Kvichak River. Page 5 of 6 Levelock Power and Fuel Facilities 9/22/04 Site Investigation Trip Report Proposed Village Tank Farm Site: The village council expressed an interest in locating any potential new fuel storage facility in the same area as existing tank farm #1 and the power plant.A preliminary site plan was developed to show that a new facility could be located on the available village-owned property in this vicinity and meet all code separation and setback requirements (see attachments).According to preliminary data,both lots 1 and 2,block 9A are owned by the Village.
