On Friday April 14 &15,2005,David Lockard of the Alaska Energy Authority/Rural Energy Group (AEA/REG)and John Dickerson of Alaska Energy and Engineering (AE&E)performed a site investigation to determine community energy related needs in Gustavus.A meeting was held at 9:00 AM on 4/15/05 with Gustavus Mayor Sandi Marchbanks and Richard Levitt to discuss potential energy infrastructure projects. The GDI tank farm,the GDI gas station dispensing tanks and the GEC power plant fuel tanks are all non-code compliant,in poor condition,and in need of replacement.All of these existing fuel storage facilities will be replaced with new fuel tanks located to provide adequate area and set-backs.A gasoline and diesel marine dispensing facility will be installed on a new City-provided fuel float at the Gustavus dock. None of the existing tanks are suitable for reuse.Five new single wall bulk tanks located at the tank farm site,three new single wall dispensing tanks located at the gas station site and one double wall intermediate tank located at the new modular power plant site will be provided to meet the projected fuel storage and dispensing requirements for the community.The new bulk tank farm will have a gross storage (tank shell)capacity of 50,000 gallons of #2 diesel fuel,30,000 gallons of #1 diesel fuel,60,000 gallons of unleaded gasoline and 10,000 gallons of avgas for a combined gross storage capacity of 150,000 gallons.The gas station will receive new 3,000 gallon dispensing tanks for #2 diesel,#1 diesel and unleaded gasoline for a combined gross storage capacity of 9,000 gallons.The power plant intermediate tank will have a gross storage capacity of 3,000 gallons.Fuel will be Gustavus Energy Infrastructure Projects November 14,2005 Concept Design Report Alaska Energy and Engineering delivered to the bulk tank farm by barge.The gas station and power plant intermediate tank will have truck delivery.A new one-half mile long single-phaseburieddistributionextensionwillberuntothetankfarmandGustavusdocksites. The existing Gustavus Electric Company power generation equipment is in poor condition and in need of replacement.A new prefabricated modular diesel power plant will be located near the existing power 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.The RPSU project will also include switchgear at the Falls Creek hydroelectric powerhouse and buried fiber optic communication cable between the Falls Creek powerhouse and the new Gustavus modular diesel power plant. Power distribution upgrades will include new automatic sectionalizing equipment for integration of proposed hydroelectric generation into the existing Gustavus distribution system and to feed the proposed Bartlett Cove intertie.A new community feed step-up transformer will be installed at the new power plant. The proposed Falls Creek hydroelectric facility received FERC permitting in 2005. Once completed,the Falls Creek hydroelectric generation plant will be the primary source of electric power for the community of Gustavus and the NPS facility at Bartlett Cove (provided the proposed intertie is constructed).The hydroelectric facility will have a minimal storage dam and will operate essentially as a run of the river system.The project will include access roads,a diversion/intake structure,a piped water conveyance system,a pre-engineered metal powerhouse building,a single 800kW capacity turbine powered generator and a 5 mile long transmission line to the GEC diesel power plant. The proposed Bartlett Cove Intertie project consists of the construction of an eight mile long buried cable "express feeder”intertie along Gustavus Road from the GEC power plant to the furthest eastern extent of the existing Bartlett Cove distribution system. The proposed project schedule calls for design and permitting of the BFU and RPSU projects to occur simultaneously and to be completed by fall 2006. Construction will occur during summer 2007 with the facilities fully functional by fall 2007.The hydroelectric project design will be completed in phases,with the architectural/civil design to be completed by late winter 2005 and the mechanical/electrical/power distribution design to be completed by summer 2006. The hydroelectric project will be constructed over the course of the 2006 and 2007 construction seasons.It is to be completed and fully functional by the fall of 2007. The Bartlett Cove intertie project design will be completed by fall 2006,with construction occurring during the 2007 construction season.It is to be completed and fully functional by the fall of 2007. The estimated cost of the BFU portion is $1,683,579,which equates to a unit cost of $10.59 per gallon based on a gross storage capacity of 159,000 gallons.This Gustavus Energy Infrastructure Projects November 14,2005 . Concept Design Report Alaska Energy and Engineering is within the Denali Commission benchmark cost range of $12.00 to $9.50 per gallon for 100,001 gallon to 200,000 gallon capacity tank farms. The estimated cost of the RPSU portion is $1,597,782 which equates to a unit cost of $2,250.40 per kW based on a total installed capacity of 710kW.This 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 estimated cost of the Falls Creek hydroelectric project is $5,425,000.The hydroelectric facility is expected to provide an average of approximately 2 million kWh of electricity annually to the community of Gustavus for the near term future. The primary benefit of this project will be the avoided fuel cost.Assuming a diesel generation efficiency of 12kWh/gallon of fuel,this represents an equivalent of 167,000 gallons of diesel fuel saved.Based on an estimated fuel price of $2.50/gallon,the annual savings from decreased fuel purchases are estimated to be approximately $417,500. The estimated cost of the Bartlett Cove Intertie project is $2,432,342.The intertie is expected to provide Bartlett Cove with an average of approximately 1.2 million kWh of hydroelectrically generated power annually for the near term future.The primary benefit of this project will be the avoided fuel cost.Assuming a diesel generation efficiency of 12kWh/gallon of fuel,this represents an equivalent of 100,000 gallons of diesel fuel saved.Based on an estimated fuel price of $2.50/gallon,the annual savings from decreased fuel purchases are estimated to be approximately $250,000.

New construction and other community improvements can adversely impact the adequacy of existing utilities.The following infrastructure projects have beenidentifiedforthecommunityofGustavus. Gustavus Dock -The Gustavus dock was built in 1955.It is of timber construction and is supported on wooden piles.There is a 10'wide access pier that extends approximately 1,200 feet from the beach to a 50°wide x 75'longmaindockarea.A series of floats accessed by a ramp from the main dock area extend approximately 125 feet to the east of the main dock.The long,narrowaccesspierallowsforone-way traffic only and space on the main dock is verylimited.|Because of these limitations the dock is highly congested during the 6 Gustavus Energy Infrastructure Projects November 14,2005 Concept Design Report Alaska Energy and Engineering - summer months with recreational boaters,fishing guides,commercial fishermen, and tour operators all attempting to stage activities over the dock simultaneously.The City is actively pursuing funding for a new dock facility.Increased access for recreational and other boating activities resulting from an improved dock facility would have a long term impact on summer season fuel use quantities in Gustavus. Marine Dispensing -There are many private boat owners and sport fishingcharteroperatorsaswellasafewremainingcommercialfishermenoperatingoutofGustavus.There is no local low tide accessible boat harbor so that during thesummerboatingseasonasmanyassixtyvesselsmaybemooredinthearea near the Gustavus dock at any given time.The nearest marine dispensingfacilityisattheNPSBartlettCovedock,a distance of approximately 15 milesonewaybyboat.Therefore most local boat owners opt to fuel their vessels from the Gustavus dock using small truck mounted fuel tanks..Because of the long,narrow dock access ramp and limited space available on the dock,this activitycancauseextremecongestionduringthebusysummertouristseason. Due to the inconvenience and inherent risks associated with this current method of fueling vessels,there is strong public support for a marine dispensing facility.However,the State Fire Marshall has denied a previous permit application toinstallfuelingequipmentonthedockduetheInternationalFireCode(IFC)requirement that marine dispensing must be from a dedicated dock or float. Code also requires that all fuel dispensing be done by pump (no gravitydispensing)and there is currently no electrical service at the Gustavus dock or nearby bulk fuel tank farm.Either the construction of a new dock facility withdedicatedfuelingareaortheinstallationofadditionalpilingsattheexistingGustavusdocktosupportadedicatedfloatonwhichtomountamarine dispensing facility will be necessary in order to meet this code requirement.Design and installation of the new dock or new piles and float must be providedtotheprojectbythecommunityduetothefundingconstraintsoftheBFU program.A conceptual design and cost estimate of required mechanical andelectricalsystemsforanewfloat-mounted dual product marine dispensingfacilityisincludedinSection5.1 of this report. The improved convenience and availability of fuel at a new marine dispensingfacilitywouldlikelyincreasetheseasonaldemandofbothgasolineand#2 dieselbymakingitpossibleforboatsfromJuneauandothersoutheastcommunitiestoacquirefuelinGustavusaswellasmakingfuelingmoreconvenientforlocals. Following are all estimated impacts of near term future growth on fuelconsumptionduringthepeak2-month delivery period for each product: e Increased seasonal marine fueling and other tourist activity -10,000 gallon increase in unleaded gasoline sales during peak summer season (20,000gallonannualincreasefromtourismandpopulationgrowth). e Also allow for 2,500 gallon increase in avgas sales during peak summerseason.(3,000 gallon near-term future annual increase). e Continued steady increase in local residential population -5,000 gallonincreasein#1 diesel sales during peak winter heating season and 5,000 gallon increase in peak summer season Jet A sales due to increased jettraffic(20,000 gallon near-term future annual increase). Gustavus Energy Infrastructure Projects November 14,2005 Concept Design Report Alaska Energy and Engineering 3.2 Alternative Energy/Efficiency Improvements A description of the proposed Falls Creek hydroelectric project is included inSection5.3 and a description of the proposed Bartlett Cove Intertie project isincludedinSection5.4.In 2004 Gustavus Electric Company and the National Park Service at Bartlett Cove used a combined 217,908 gallons of diesel fuel forpowergeneration.If constructed and operated as proposed,it is anticipated thatthehydroelectricfacilitywillsupplyapproximately90%of the total electricdemandforbothlocations,provided that the Bartlett Cove intertie is constructed. At 2004 electrical consumption levels this would result in annual savings ofapproximately130,000 gallons of #2 diesel for GEC,with an additional savingsofapproximately65,000 gallons at Bartlett Cove. 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 sizingandselectionofnewdiesel-electric generators in conjunction with the installationoffullyautomaticparallelingswitchgearanddistributionimprovementswillresultinoptimumcommunitypowergenerationfuelefficiency. There are no identified facilities,such as a school or public building,within apracticaldistanceoftheproposedpowerplantlocationthatcouldbenefitfrom recovered engine heat.In addition,since the average annual run time of thedieselgeneratorsisexpectedtobeminimal(less than 1,000 hours per year)it isdoubtfulthatheatrecoverycouldeverbecosteffective.Based on thiscombinationoffactorstherearenoplanstoinstallheatrecoveryequipmentinthenewpowerplantmodule. The Alaska Energy Authority/Alaska Industrial Development and Export AuthoritypublishedadraftRuralAlaskaEnergyPlandatedDecember31,2002 as a follow-up report to the previously released Screening Report of Alaska RuralEnergyPlandatedApril2001.The Screening Report evaluated a dozen alternative energy technologies other than diesel engine heat recovery.OnlywindenergywasidentifiedasalternativeenergytechnologywarrantingfurtherevaluationinthedraftRuralAlaskaEnergyPlan.According to the Wind EnergyResourceAtlasoftheUnitedStatesthecommunityofGustavusislocatedwithin a class 3 wind regime and is not a viable candidate for a wind energy programusingcurrentlyavailabletechnologies. An energy audit was performed and a series of energy efficiency measures wererecommendedbytheAlaskaEnergyAuthorityinthespringof2001.Thesesuggestedimprovementsincludedreplacementofexistinglightingfixtures,the installation of storm windows,additional attic and floor insulation,new door weather stripping,replacement of electric water heaters with oil-fired units ordemandelectricheaters,replacement of electric baseboard heat with Monitor- style heaters,as well as other suggested energy efficiency improvements incommunitybuildings.A report is available from AEA on these suggestedmeasures,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 Gustavus.At this time,it appears that supplementalhydroelectricgenerationandpossiblyadditionalend-use conservation are theonlyviableenergyreductiontechnologiesavailableforGustavus. 3.3.Tank Capacity Requirements Gustavus is located on a year round ice-free port with a deep water dockcapableofreceivingocean-going fuel barges.In interior and northern Alaskan 8 November 14,2005GustavusEnergyInfrastructureProjects Alaska Energy and EngineeringConceptDesignReport 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 communityhashistoricallyaveragedeighttotenbargedeliveriesperyear,spaced from onemonthtotwomonthsapartandfuelbargesarenormallyscheduledtobeintheareaatleasteverythreetofourweeks. Due to limited existing fuel storage capacity and increasing demand,bargedeliveriesareoftennowrequiredatonemonthintervalsduringthepeakseasonaluseperiodsforunleadedgasoline(summer)and #1 diesel fuel (winter).Requiring fuel deliveries on such short intervals makes the community's fuelsupplyvulnerabletoanyunforeseendisruptioninbargeserviceandalsoincreasestheamountoffuelhandlingrequired,thereby increasing the chancesofafuelspill.Therefore,the proposed new facility has been sized to hold anapproximatetwomonthssupplyofeachproductbasedonthepeakuseperiodforthatproduct. 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 onthispricestructure,the facility has been sized to have at least 20,000 gallons oftotalavailablecapacityperscheduleddelivery.During abnormally high fuel useperiods,such as during a major road construction project,additional fueldeliveriescanbescheduledasrequired. The annual community consumption of #2 diesel fuel has the potential to bedramaticallyreducedwhenthehydroelectricfacilityisconstructed.However,thispotentialreductionwillbeignoredforthepurposeofcalculatingtherequired#2dieselfuelstoragecapacityfortheBFUproject.This is done to ensureadequatefuelstoragefordiesel-electric power generation for the proposed twomonthfuelbargedeliveryscheduleintheeventofanunforeseenlong-termoutageatthehydroelectricfacility.

There are four generators installed in the power plant.Unit #1 is a 250kWCumminsKTA19-G2,unit #2 is a 300kW Caterpillar D353E-TC,unit #3 is a100kWCaterpillarD342-6 and unit #4 is a 500kW Cummins VTA12-800GS. Unit #1 has over 30,000 total hours.Units #2 and #3 are high-hour antiquatedmodelsthatarenolongerinproduction.Unit #4 is a low hour unit that was purchased used several years ago and is seldom in service as it is somewhat oversized for existing community loads. Generators #1 and #3 are on a common cooling manifold with two remote radiators.Generator #2 has a skid-mounted radiator with belt-driven fan. Generator #4 is on a stand-alone cooling system with one remote radiator. Power generation from unit #1 is at 480V 3-phase,which is then stepped up to2,400 volts through an exterior transformer bank prior to being routed to theswitchgear.Power generation from units #2 through #4 is at 2,400V 3-phase.There is a 2,400V to 12.47/7.2kV distribution step-up transformer bank within the fenced area adjacent to the power plant.The manual paralleling switchgear is a combination of cabinets of various makes and models that were purchased used and field modified as needed for installation. 5.2.2 New Modular Power Plant The proposed new modular power plant will contain three generators sized incombinationtomeetpeakcommunityloads,including an allowance for neartermfuturegrowth,as well as to efficiently meet anticipated peak-adding loadsforaugmentinghydroelectricpowerwhenrequired.The proposed power plant 15 Gustavus Energy Infrastructure Projects November 14,2005 Concept Design Report Alaska Eneray and Engineering will also include programmable automatic paralleling switchgear,a fire suppression system and critical grade exhaust silencers as well as all requiredenginecoolantpipingandventilationequipment.It will come pre-assembled in a15'-8"W x 41'-8"L modular skid-mounted building.The engine cooling systemwillconsistof3"copper coolant supply and discharge piping manifolds and dualremoteradiatorswithvariablespeedcontrol.A new automatic fill 100 gallon fueloildaytankwillbeinstalled.It will be equipped with redundant overfill protectionandalarmsystems,a hand priming pump,and a totalizing meter.Welded steelfuelpipingwillbeinstalledwithintheplant.The modular power plant layout isshowninAppendixA,Power Plant Plan Sheet E1. A 3,000 gallon double wall intermediate tank equipped with required overfillprotectiondeviceswillbelocatedapproximately5'from the module andconnectedtothedaytankwith1"welded steel supply and pump-down pipelines.The supply pipeline will include a flanged 1"actuated ball valve located at the tank connection for automatic isolation of the tank between day tank fill cycles.The EPA requires surface flow containment around a fuel truck during fueltransferstoaregulatedfacilityinordertopreventfuelspillsfromenteringnavigablewaters.Surface flow containment requirements for the power planttankwillbemetbygradingthetruckstagingareaawayfromthedrainageditchthatrunsbehindthepowerplantproperty.The power plant site is shown inAppendixA,Gustavus Electric Power Plant Site Plan Sheet M8. 5.2.3 Generation Equipment PCE data for GEC from 2001 through 2004 was analyzed to determine currentcommunitypowerdemand.During this period the peak operator observeddemandinGustavuswas320kWinJulyof2002.Power monitoring andrecordingequipmentwasinstalledinthepowerplantinAugust,2005 in order tomoreaccuratelydeterminetheelectricaldemandprofileforthecommunity.Thisloaddatawillbeusedforfinalverificationofgenerationequipmentsizingforthenewpowerplant.The GEC power plant generation capacity will not be affectedbytheproposedBartlettCoveintertiebecauseitisassumedthatBartlettCove would revert to self generation if available hydroelectric power generation fellbelowtheGustavusdemandorwasinterruptedforanyreason.The GustavusPCEdataaswellasavailableBartlettCovedataisincludedinAppendixD. Because the diesel power generation will only operate a small percentage of theyear,it is acceptable to parallel two units to meet the peak load.Ideally the newpowerplantshouldhavethreegeneratorssizedsothatanytwowillhave sufficient combined capacity to meet normal peak community loads.One of thegeneratorswillbesmallerthantheothertwotoallowformoreefficientoperationwhendeceasedamountsofdieselpowerisrequiredtomeetpeaksduringpeak- adding periods.It is proposed that a pair of 260kW prime rated generators and a single 190kW prime rated generator be installed,for a total installed capacity of 710kW. The new diesel plant switchgear will have a total of 4 sections -one for each diesel generator and one for master control,distribution and metering.Theswitchgearwillbefullyautomaticwithparallelingcapabilityandwillutilizeaprogrammablelogiccontroller(PLC)to automatically match the runninggenerator(s)to the community load,including for hydroelectric peak adding.Thedistributionsectionwillincludetwo480Vfeeders,each with separate circuit breakers and metering -one for power plant station service and one for GECdieselpowerdistributionthroughthepad-mounted step up transformer banklocatedadjacenttothepowerplant.Relays will be included as required to 16 Gustavus Energy Infrastructure Projects November 14,2005 Concept Design Report Alaska Energy and Engineering remotely control the hydroelectric distribution sectionalizing cabinet,also locatedadjacenttothepowerplant.A data communication cable from the Falls Creek powerhouse will allow paralleling of the hydro turbine with the diesel generators as well as remote monitoring of hydroelectric generation.Totalizing meters willbeinstalledinthedistributionsectiontorecordGEChydroelectricfeederandBartlettCoveIntertiepowerusage.Final selection of the hydroelectric turbinecontrolschemeanddatacommunicationcablebytheHydroelectricprojectengineersmustbecompletedpriortodieselplantswitchgeardesigninordertoassurecompatibility. 5.2.4 Hydroelectric Controls The hydroelectric powerhouse electronic controls,switchgear and datacommunicationssystemsareincludedintheRPSUprojectscope.This willensurepropercoordinationbetweentheFallsCreekhydroelectricandGustavusdieselpowergeneration/distribution systems.It will also reduce the level ofcoordinationrequiredbetweendesignteamsfortheproductionoffinalFallsCreekhydroelectricandGustavusRPSUdesigns.The installation of a directburial6-pair fiber optic cable with the proposed buried transmission line will allow for hydroelectric data acquisition and provide information to the new diesel plantswitchgearforautomaticstartupofgeneratorsforpeakshavingorprimegenerationasdeterminedbytheloadandwaterflowavailable.The hydropowerhouseswitchgearwillhavesectionsforcontrolandmeteringaswellasforthemainbreakeranddistribution.It will be fully automatic with parallelingcapabilityandwillutilizeaprogrammablelogiccontroller(PLC)to automaticallymatchtheturbineoutputtotheavailablewaterflowandcommunityload.Thedistributionsectionwillincludethemaingeneratorbreaker,potentialtransformers,and a fused switch or circuit breaker for station service power.Power will be stepped up from the 480V generation voltage to a 12.47/7.2kV fordistributiontothecommunityacrossthefivemilelongtransmissionline.On theprimarysideofthestep-up transformer a fused disconnect will be installed for conductor protection and plant isolation. 5.2.5 Distribution Upgrades GEC distribution upgrades will include the following components: e New 500 kVA,3-phase,480V to 12.47/7.2kV pad mount transformer bank to match the new diesel power plant and existing GEC distribution voltages. e New automatic sectionalizing relay/breaker cabinet for hydroelectric power distribution to GEC and Bartlett Cove. 5.3 Hydroelectric Project Once completed,the Falls Creek hydroelectric generation plant will be theprimarysourceofelectricpowerforthecommunityofGustavusandtheNPSfacilityatBartlettCove.The hydroelectric facility will have a minimal storagedamandwilloperateessentiallyasarunoftheriversystem.It will consist of the following components: e 3.6 miles of single lane gravel surface access roads. e Concrete diversion/intake structure with pneumatic spill gates. e 9,400'total length combination HDPE and steel pipe water conveyance power conduit. 17 Gustavus Energy Infrastructure Projects November 14,2005 Concept Design Report Alaska Energy and Engineering e 30'x 45'metal powerhouse building with reinforced concrete foundation. e Single 1,100 HP turbine with 800kW capacity generator. e 5 mile long buried 3-phase 12.47/7.2kV transmission line. e Data communication line co-buried with transmission line to GEC diesel power plant. A more complete description of the proposed Falls Creek Hydroelectric projectalongwithpreliminaryplansisincludedinAppendixEofthisreport.ThisinformationistakenfromExhibitsAandFoftheGEChydropowerlicenseapplicationassubmittedtotheFederalEnergyRegulatoryCommission(FERC)in 2001. 5.4 Bartlett Cove Intertie Project GEC currently serves approximately 200 customers in Gustavus with an annual average community load of around 200kW and a peak load of around 350kW.The proposed Falls Creek hydroelectric facility will be capable of generating upto800kW,well in excess of the current peak GEC demand The National ParkService's (NPS)Glacier Bay National Park and Preserve facility at Bartlett CoveisapproximatelytenmilesfromGustavus.The NPS operates a powergenerationanddistributionsystematBartlettCovewithanannualaverageloadofaround122kWandapeakannualloadofapproximately180kW.BartlettCoveisnotcurrentlyconnectedtotheGECgrid.The engineering firm of D.Hittle &Associates recently prepared a report for the NPS analyzing the longtermcostofselfgeneratingversusthecostofpurchasingpowerfromGEC,assuming that the Falls Creek hydro project is constructed.The reportconcludesthatthemostcosteffectivelongtermoptionwillbefortheNPStopurchasehydroelectricpowerfromGEC.The economic analysis of the preferredoptionisbasedontheconstructionofaneightmilelong"express feeder”intertiealongGustavusRoadfromtheGECpowerplanttothefurthestextentofthe existing Bartlett Cove distribution system.At this time there have been no direct negotiations between GEC and NPS regarding a future power agreement. The conceptual design is based roughly on the "Express Feeder"option in the D.Hittle report and consists of the following components: e Connection to a hydroelectric padmount sectionalizing cabinet with vacuumswitchesandprotectiverelayinglocatedintheGECpowerplantyardandcontrolledbytheGECpowerplantswitchgear. e Approximately eight miles of buried 3-phase12.47/7.2kV transmission line. e A total of nine reactors with three located at each end and three located atthemidpointoftheburiedtransmissionlineforpowerfactorcorrectiondueto buried conductor capacitance. e An automatic disconnect cabinet located at the connection to the existingBartlettCovedistributionsystem.This disconnect provides for completeisolationoftheeightmilelongburiedtransmissionlineonlossofpowerfromGECandwillpreventlossesassociatedwithenergizingthetransmissionlinewhenBartlettCoveisselfgeneratingwithdieselpower. e Minor protective and control renovations to the Bartlett Cove power plant. The proposed intertie does not include data communication between the GECandBartlettCoveswitchgear,nor does the transmission line run all the way to 18 Gustavus Energy Infrastructure Projects November 14,2005 Concept Design Report Alaska Eneray and Engineering the Bartlett Cove power plant switchgear.Because of these limitations,it will not be possible to parallel GEC power with a hot Bartlett Cove distribution system.Therefore it will always be necessary to black out the community of Bartlett Covepriortoenergizingtheintertie.This should be a rare occurrence and could easilybescheduledfortimethatwouldcauseminimumdisruptions. With minor renovations to the Bartlett Cove power plant it should be possible toparallelBartlettCovegeneratorstothedistributionsystemwhenalreadyenergizedfromtheGECintertie.Therefore a planned disconnection of the intertie may not require a Bartlett Cove black out. 5.5 Proposed Operating Scenario A long term agreement between Gustavus Electric Company,Gustavus Dray,Inc.and the City of Gustavus (potential grantee of construction funding)will needtobedraftedinordertodefineownershipandoperatingagreementsfortheFallsCreekhydroelectricfacility,diesel power plant,power distribution improvements,bulk fuel storage facility,gas station improvements,and marine dispensingfacility.This agreement must be in place prior to drafting the business plan andbeginningthefinalprojectdesign. Management responsibilities of the new tank farm include:maintenance and operation of all tanks,pumps,and piping systems;annual pressure testing ofpipelines;maintenance and replacement of spill response equipment andsupplies;and snow removal.These operating costs should be determined on apergallonofthroughputbasis(as part of the required Denali Commission FacilityBusinessPlan)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 will besubjecttoRegulationsofbothStateandFederalagenciesincludingtheAlaskaCoastalManagementProgram,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.ArmyCorpsofEngineers,the State Historic Preservation Office,and other divisions within the Alaska Department of Natural Resources may become involved.In addition,the hydroelectric facility will be constructed and operated under an existing license from the Federal Energy Regulatory Commission (FERC). 6.1 Environmental Assessment An Environmental Assessment (EA)will be completed prior to construction of theproposedproject.An EA is required for all projects that are federally funded orrequireafederalpermit(such as a Corps of Engineers Wetlands Permit).TheEAdetermineswhetherthereisasignificantimpacttotheenvironmentcaused by the project.As part of the EA,a Coastal Zone Management ProjectQuestionnairewillbecompletedandsubmittedtotheAlaskaCoastal Management Program.The Coastal Zone Management Project Questionnairewillhelpidentifystateorfederalpermitsthatmayberequired.A Corps ofEngineerswetlandspermitshouldnotberequiredforconstructionasallfillmaterialwillbeplacedinuplandsandnotinnavigablewaters.However,theneedforapermitwillbeinvestigatedfurtherwiththeCorpsofEngineersearlyin the permitting phase. 6.2 Fire Code 19 Gustavus Energy Infrastructure Projects November 14,2005 Concept Design Report __.Alaska Energy and Engineering A Plan Review permit from the State Fire Marshal is required for the bulk fuel and power generation systems.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 codesincludingtheInternationalBuildingCodeandtheNationalElectricalCode.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 isallowedtoproceedpriortoapprovalbutthepermitmustbeinplacepriortoplacementoftanksorsimilarinstallation.Plans should be submitted byDecemberorJanuarytoensureapprovalintimeforspringconstruction. 6.3.Spill Response Because the new City bulk tank farm will have oil storage tanks in excess of1,320 gallons and will receive delivery by marine vessel,it will be subject to U.S.Environmental Protection Agency and U.S.Coast Guard regulations.AnOperationsManualandLetterofIntentwillbepreparedandsubmittedtotheCoastGuard.An Oil Spill Response Plan will be prepared and submitted to boththeCoastGuardandtheEPA.The tank farm will require preparation of a SpillPreventionControlandCountermeasures(SPCC)plan.This plan will addressalltankswithacapacityof55gallonsorgreater.The gas station and powerplantwillnotreceivemarinedeliveriesandarethereforenotsubjecttoCoastGuardregulationsbutwillrequireSPCCplans.The required Coast Guard andEPAplanswillbeprepareduponcompletionoffacilityconstructionasacoordinatedpackage.

granteeactingastheemployerandutilizingprimarilylocallabor.This method tends toachieveahigherpercentageoflocalhireandisstronglysupportedbymanycommunitiesandfundingagencies.The highly technical nature of tank farm and power generation projects requires a limited number of workers with specificexperienceandexpertisetobebroughtinfortheprojectwhennotavailable 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 skilledcraftsmenwithappropriatecertifications.An experienced construction manager will be required to recruit the necessary skilled labor,coordinate the constructionteam,and oversee procurement and project logistics.The design engineer will provide quality control through communication with the construction managerandperiodicon-site inspections. 7.1.Local Job Skills An inquiry was made to the

The estimated cost of the RPSU portion is $1,597,782,which equates to a unitcostof$2,250.40 per kW based on a total installed capacity of 710kW.This iswithintheDenaliCommissionbenchmarkcostrangeof$2,400 to $1,900 perinstalledkWfor601kWto800kWcapacitypowerplants. The estimated cost of the Falls Creek hydroelectric project is $5,425,000.The hydroelectric facility is expected to provide an average of approximately 2 million kWh of electricity annually to the community of Gustavus for the near term future.The primary benefit of this project will be the avoided fuel cost. Assuming a diesel generation efficiency of 12kWh/gallon of fuel,this represents an equivalent of 167,000 gallons of diesel fuel saved.Based on an estimated fuel price of $2.50/gallon,the annual savings from decreased fuel purchases are estimated to be approximately $417,500. 24 Gustavus Energy Infrastructure Projects November 14,2005 Concept Design Report .Alaska Energy and Engineering The estimated cost of the Bartlett Cove project is $2,432,342.The intertie is expected to provide Bartlett Cove with an average of approximately 1.2 million kWh of hydroelectrically generated power annually for the near term future.The primary benefit of this project will be the avoided fuel cost.Assuming a diesel generation efficiency of 12kWh/gallon of fuel,this represents an equivalent of 100,000 gallons of diesel fuel saved.Based on an estimated fuel price of $2.50/gallon,the annual savings from decreased fuel purchases are estimated to be approximately $250,000. 25 7APPENDIX A

Review A detailed cost estimate for this project was obtained from Larry Coupe of Alaska Power and Telephone (AP&T).This estimate was prepared by Mr.Coupe in 2001 and was the basis for the cost estimate included in the license application.Mr.Coupe noted that the cost estimation for the road came from directly from GEC,who had a road contractor provide an estimate.The total of this 2001 estimate was $4,130,000.This estimate is very detailed and while not reviewed in detail,appears sound. 'Mr.Coupe updated this estimate with a memo in July 2005 to provide a preliminary assessment of the cost increases associated with the recent spike in materials prices.This assessment increased the estimated cost of the project by $275,000.This assessment was based on recent bid prices and appears sound. Mr.Coupe also noted that the cost estimate for the license application included the following amounts which are not shown in the FERC summary sheet: 'Escalation from 2001 to 2005 $520,000 Interest during construction $380,000 Financing costs $120,000 The escalation from 2001 to 2005 was based on a 3%annual inflation rate.In comparison,the ENR tonstruction cost index increased by 19%for this period.When the $520,000 escalation is added to the '$275,000 escalation due to materials,the total escalation is approximately equal to the escalation estimated by the ENR index ,so this number was also judged to be sound. Summary A summary of the cost estimate is as follows 2001 construction cost estimate $4,130,000 2005 materials price increases $275,000 Escalation from 2001 to 2005 $520,000 2005 construction cost estimate $4,925,000 Interest during construction $380,000 Financing costs __$120,000 Total (2005 dollars)$5,425,000 HDR Alaska,Inc.2525 C Steet Phone (907)644-2000 Page 1 of1Suite305Fax(907)644-2022 Anchorage,AK 99503 www.hdrine.com EXHIBIT A PROJECT DESCRIPTION 1.INTRODUCTION The Falls Creek Hydroelectric Project (Project)will be located approximately 5 miles east of Gustavus,Alaska,as shown in Exhibit G.The Project will utilize a portion of the flow and head of Falls Creek,which is also known as the Kahtaheena River. The Project will be a run-of-river project,generally consisting of 3.6 miles of access road,a diversion/intake structure at about El 670,a single-unit power plant with an installed capacity of 800 kW,a pipeline and penstock system approximately 9,400 feet long,and 5.0 miles of buried transmission line.Details of these facilities are presented below and in Table A-1.Preliminary design drawings are presented in Exhibit F,including a general plan in Exhibit F-1.The expected cost of the project,the proposed mode of operation,and the expected utilization of the generation are also described in this Exhibit. 2.PROPOSED PROJECT FACILITIES 2.1 Access Roads The alignment of the proposed access road is shown in Exhibit G.The access road will start from the end of the existing road system (Rink Creek Road),and is generally aligned to avoid sensitive wildlife habitat near tidewater.At about El 650 (1.7 miles from the start),the road will branch,with one branch proceeding 0.5 miles north to the diversion/intake structure and one branch proceeding 1.4 miles south to the power plant. The access road will be a single-lane gravel-surfaced road with turnouts,similar to a logging road.A locked gate will be located at the start of the road to limit access by non-project vehicles.The grade of the road will generally be less than 6%.Short segments will be steeper. In particular,the 600-foot long section above the powerhouse will have a grade of nearly 20%. Most of the road will be constructed with a balanced cut-and-fill cross section.In unstable or steep areas,the road will be constructed with a full-bench excavation to minimize loading on the downslope.Typical road cross-sections are shown in Exhibit F-2. 2.2 Diversion/Intake Structure The diversion/intake structure will be located 2.39 miles upstream of the mouth of Falls Creek (SM 2.39)where the stream is confined by rock abutments and drops several feet in a short distance.The structure will include a gated section 36 feet long centered over the existing stream channel,a concrete wall on the left abutment (looking downstream),and the intake on the right abutment.The preliminary design of the diversion/intake structure is shown in Exhibits F-3 and F-4. Falls Creek Hydroelectric Project A-]Application for License FERC Project No.11659 October,2001 The gated portion of the diversion structure will be sized to provide a spill capacity equal to or greater than the 100-year frequency flood.It will also provide a means of flushing accumulated sediment from the diversion pond.It will consist of:- e Aconcrete gate foundation and stilling basin; e A 36 feet long steel gate,which will raise the water 5 feet above the gate foundation (to El 665).The gate will include two independently-operated panels.The panels will be raised and lowered by air pressure in large rubber "pillows”.The control system will automatically operate the gate to maintain a constant water surface. e Concrete retaining walls on each end of the gate. The intake structure will be located adjacent to the west end of the diversion gate.It will utilize a modified 20-foot shipping container initially installed as a flume for diversion of the stream during construction of the gate.It will subsequently be fitted with a trashrack,fishscreen, instream flow release facility,square-to-circular transition,and butterfly-type shutoff valve.The trashrack will be raked manually when needed,based on continuous monitoring of the head loss across the rack. An additional 20-foot shipping container will be stacked over the intake to house the power, control,and monitoring equipment.The intake and control containers will be encapsulated in concrete for protection from the elements. The fishscreen will consist of two vertical panel screens oriented in a V shape,with the panels aligned 30°to the direction of flow.The panels will have 3/32-inch perforated plate faces in accordance with NMFS criteria for fry-sized salmonids.At the apex of the V will be the entrance to the bypass,which will include an upward sloping ramp,an overflow control gate,a downwell,and a 10”bypass conduit discharging into the spillway stilling basin.The screens will be cleaned by an automatically-controlled motor-operated brush system. The diversion/intake structure will create a small pond with a surface area of about %acre and a maximum depth of 5 feet.The incremental surface area will be only 4 acre.Because of the proposed run-of-river operation,there will be no active storage in the diversion pond. 2.3.Power Plant The power plant will be located 0.45 miles upstream from the mouth of Falls Creek,and 0.21 miles downstream of an 80-foot high waterfall known as the Lower Falls.The preliminary design for the power plant is shown in Exhibits F-5 and F-6.The power plant will include: e A 30-foot-by-45-foot metal building and concrete foundation, e One generating unit that includes a 20-inch butterfly-type turbine shutoff valve,a 1100- HP two-jet horizontal axis impulse turbine,a direct-connected 800-kW generator,and a flywheel.Rotational speed will be 600 rpm.The turbine centerline will be at El 75, which will provide 590 feet of gross head.The hydraulic capacity of the turbine will be 23 cfs.The minimum discharge capability of the turbine will be about 2 cfs. e A synchronous bypass,consisting of a branch off the power conduit upstream of theturbineshutoffvalve,a 14-inch butterfly type guard valve,and a 14-inch multi-port sleeve valve.Hydraulic capacity of the bypass will be about 20 cfs. e A control system for local manual,local automatic,and remote automatic startup, synchronization,and operation. Falls Creek Hydroelectric Project A-2 Application for License FERC Project No.11659 October,2001 e A switchyard consisting of a pad-mounted 1000-kVA transformer and pad-mounteddisconnectswitch. e A tailrace system for carrying discharge from the power plant approximately 800 feetupstream.The tailrace will consist of a headbox to collect flow from the turbine and synchronous bypass,a 36-inch diameter HDPE pipeline,and an outlet structure discharging 10 feet above the normal high water level. e Miscellaneous power,lighting,hoisting,sanitation,heating,and ventilation systems. 2.4 Power Conduit The power conduit will be a pipeline and penstock system 9,400 feet long carrying water from the diversion/intake structure to the power plant.The alignment for the power conduit is shown in Exhibit F-1,and a profile is shown in Exhibit F-7.There will be five distinct segments of the power conduit,as described below: e A 3,150-foot long segment below the diversion/intake structure where the conduit will generally be buried adjacent to the access road along the side of the Falls Creek valley. The grade in this section will be very small (0.33%),and the pipe will 30-inch diameter SDR 32.5 HDPE.Approximately 700 feet of this segment will be buried up to 12 feet deep where the alignment crosses a broad ridge near the Upper Falls. e Once the conduit emerges from this broad ridge it will leave the Falls Creek valley and follow along the side or top of a plateau at about the 600-foot contour.The length of this section will be about 2,170 feet,the grade will be 0.5%,and the pipe will be 28-inch diameter SDR 26 HDPE.For most of this segment the pipe will be adjacent to the access road and buried. e At about El 600,the pipe will change to 24-inch diameter SDR 17 HDPE.The pipe will generally be adjacent to the access road and exposed,and the grade will be about 10%. The length of this segment will be about 1,090 feet. e At about El 500,the pipe will depart from the road alignment and proceed directly downhill for approximately 1,270 feet.The grade in this section will be about 15%,and the pipe will be 24-inch diameter SDR 11 HDPE.The pipe generally will be laid on the existing forest floor in this segment. e At about El 310,the pipe will change to 20-inch diameter steep pipe supported by concrete or wood saddles.The pipe will again be adjacent to the access road and exposed,and the grade will be vary from 7%to 65%,with the steep grade at a 200-foot long section immediately above the power plant.Thickness of the pipe will be about 3/16 inch,and the length will be 1,720 feet. Where the HDPE pipeline is exposed,it will be laid with continuous slight bends to provide for thermal expansion and contraction.The exposed steel pipe section will include thrust blocks and sleeve-type expansion joints at each change in alignment to allow thermal expansion and contraction. 2.5 Transmission Line The transmission line will be 5.0 miles long from the power plant to an interconnection with the existing system at the diesel power plant substation.The transmission line will be buried for its entire length,3.0 miles in or adjacent to the proposed access road and 2.0 miles adjacent to an Falls Creek Hydroelectric Project A-3 Application for License FERC Project No.11659 October,2001 existing undeveloped ORV trail.Cable will be C-L-X Type MV-105 15 kV shielded powercable,and the voltage will be 12470/7200 grndY. 2.6 Environmental Measures The Applicant proposes to incorporate the following measures into the project development toavoid,reduce,or mitigate potential environmental impacts: e Locate the powerhouse to return flow to Falls Creek rather than directly to tidewater. This preserves most of the anadromous fish habitat in Falls Creek,but increases the length of the power conduit and access roads,and makes the powerhouse more difficult to construct.The approximate cost of this change is $1,200,000. e Locate the intake about 300 feet downstream of The Islands area to avoid impacts to that productive Dolly Varden habitat.The cost of the intake structure is approximately the same,but there is less head which results in a loss of generation that over the life of the project could have a present worth of as much as $57,000. e Raise the powerhouse and install the tailrace pipeline to return flow to the base of the Lower Falls in order to avoid any bypass of anadromous fish habitat.This results in increased construction costs for the powerhouse of approximately $155,000 and a loss of generation that over the life of the project could have a present worth of as much as $51,000. e Install a synchronous bypass at the powerhouse to allow load-following generation without causing harmful stage fluctuations in the anadromous fish habitat below the tailrace.The synchronous bypass also provides a redundant flow continuation capability to avoid dewatering of the anadromous fish habitat during a forced outage event.The construction cost of the synchronous bypass is estimated to be $100,000. e Provide minimum instream flows in the bypass reach varying from 5 cfs to 7 cfs to maintain a small population of Dolly Varden char in the bypass reach.This results in a loss of generation that over the life of the project could have a present worth of as much as $1,110,000. e Provide a fishscreen and bypass system suitable for exclusion and downstream passage of fry-sized salmonids.The increased cost associated with the fishscreen and bypass is $61,000. e Access project facilities almost exclusively via upland routes to avoid impacts to wildlife habitat in the beach area.This will increase the construction cost by approximately $360,000. e Backhaul all road cut material out of the stream canyon to reduce the possibility of mass wasting.This will increase the construction cost by approximately $215,000. The total cost of these mitigation measures in increased construction costs and the cost of lost generation is $3,154,000.This does not includes costs for additional mitigation and monitoring that may be required by conditions of the license. Falls Creek Hydroelectric Project A-4 Application for License FERC Project No.11659 October,2001 3.ESTIMATED COST OF THE PROJECT 3.1 Construction Cost The estimated construction cost is $4,130,000,as shown in Table A-2.To achieve this cost,the Applicant intends to use force-account labor as much as possible,and to purchase materials as economically as possible.The construction duration will be about two years. 3.2 Annual Cost The estimated annual cost for the hydro project for the first year of operation (expected to be 2007)is $487,000,as shown in Table A-3.An additional $89,000 is estimated to be required for supplemental diesel generation,for a total production cost of $575,000.The estimated load during the first year is expected to be 4,005 MWh,which results in a production cost of 14.4 ¢/kWh.That is slightly less than the 14.6 ¢/kWh expected production cost from the existing diesel generators,assuming reasonable rates of increase in the cost of diesel fuel.The production cost with the hydro project will increase at a much slower rate than the diesel generation because much of the hydro project's cost is fixed,while the cost of diesel generation will increase due to escalation in the cost of diesel fuel. 4.PROPOSED MODE OF OPERATION 4.1 Mode of Operation The project will operate as a run-of-river project.During approximately six months of the year from May through October,there will nearly always be enough flow in Falls Creek to supply the proposed instream flow release and to generate sufficient power to meet the loads of GEC and the Glacier Bay National Park headquarters located in nearby Bartlett Cove.During this period, the project will divert at a nearly constant rate sufficient to meet the expected peak load.A portion of this diversion will by routed through the synchronous bypass at the power plant in order to avoid peaking-type variations in the diversion rate.The amount of bypass flow will vary continuously as necessary to meet the continuously varying loads.The diversion rate will be adjusted approximately weekly,and the adjustment will be made to prevent hydraulic transient conditions in the power conduit and to limit the water level change downstream of the power plant to less than 1 inch per hour. During the remaining six months of the year,there will frequently be less flow in the stream than necessary to meet all GEC loads.During those periods,the project will divert all flow in excess of the instream flow requirement.The diversion rate will be adjusted automatically to maintain a constant diversion pond level.The adjustments to the diversion rate will be made slowly to limit the water level change downstream of the power plant to less than 1 inch per hour. 4.2 Instream Flow Requirements The Applicant proposes to release flow from the diversion/intake structure to maintain a population of Dolly Varden char in the bypassed reach.As described in the accompanying PDEA,the Applicant has considered several factors in developing its proposed instream flow schedule.The proposed instream flow schedule is shown below,and is considered to provide an optimal balance between generation requirements and aquatic biology needs. Falls Creek Hydroelectric Project A-5 Application for License FERC Project No.11659 October,2001 Applicant's Proposed Instream Release Schedule Month Instream Release,cfs Month Instream Release,cfs January 5 July 7 February 5 August 7 March 5 September 7 April 7 October 7 May 7 November 7 June 7 December 5 4.3 Hydrology The Applicant has funded the installation of stream flow gages by the U.S.Geological Service at two locations on Falls Creek.One gage near the power plant location was in operation from October,1998 to March 2001 (USGS gage 15057590),and the other near the diversion site has been in operation since October,1999 (USGS gage 15057580).Drainage areas for the two gages are 10.7 and 10.1 square miles,respectively. Since two years of streamflow data does not provide an adequate basis for estimating potential generation by the project,the Applicant conducted two studies to extend the hydrologic record. One study estimated streamflows from precipitation records and snowmelt calculations,by which a 19-year record of average daily streamflows was synthesized.The second study extended the 2-year record to 33 years by correlating the actual gaged flows on Falls Creek with those on the Kadashan River near Tenakee Springs (USGS gage number 15106920).The drainage area of the Kadashan River gage is 10.2 square miles. Although each record has its problems,the 33-year record developed by correlation with the Kadashan River is considered by the Applicant and the agencies to be superior,and has been used to estimate generation by the project and as one basis for establishing instream flow requirements.The 33-year record of average daily streamflows was developed by application of the following equations: For November-April:Qrc=0.59*Qx«° For May-October:Qrc=2.82*Q«°>? Where Qrc=Flow in Falls Creek in cfs/mi? Qx=Flow in Kadashan River in cfs/mi2 Various forms of equations were tried,and the two shown above were determined to provide the best correlation.Use of equations for different time periods is appropriate because Falls Creek is influenced by snowfall and snowmelt more than the Kadashan River,which is influenced primarily by rainfall. Average monthly flows for the 33-year record are shown in Table A-4,and a flow duration curve is shown in Figure A-1.The estimated average annual flow is 50.8 cfs.The Applicant will continue to collect flow data to allow refinement of the hydrologic record. 5.UTILIZATION OF THE PROJECT GENERATION All of the Project generation will be utilized to serve the loads of the Applicant,which provides service to the community of Gustavus.Currently,the Applicant uses diesel generators to meet Falls Creek Hydroelectric Project A-6 Application for License FERC Project No.11659 October,2001 the loads,as does the independent Glacier Bay National Park system located nearby in Bartlett Cove.The Applicant is negotiating with the National Park Service to interconnect and supply the National Park Service loads as well when the project becomes operational. The Applicant had a load forecast prepared in 1999.Forecast loads for 2007,2010,2013,and 2016 are shown in Table A-5 (2007 is the earliest year that the project is expected to be operational).Also shown are forecast loads of the independent Glacier Bay National Park system. Generation by the Project will depend on both the available streamflow and the loads of the interconnected community.As described above,during normal and high flow periods,there will be sufficient streamflow to generate all of the expected loads,but during low flow periods the streamflow will control the amount of generation. Generation estimated by the Project for the loads shown in Table A-S (i.e.,in years 2007,2010, 2013,and 2016)is shown in Table A-5.These generation values are for an average water condition,and could vary due to higher or lower streamflows.The greatest potential average annual generation by the project (i.e.,not restricted by loads)is estimated to be 5,500 MWh.

ELD LaeRICHARD1.LEVIN?PRESIDENT GUSTAVUS ELECTRIC COMPANY GUSTAVUS ELECTRIC COMPANY.FALLS CREEK..HYDROELECTRIC PROJECTAPPLICATIONFORLICENSEFORMINORPROJECT EXHIBIT G-1 PROJECT MAP 2000 SCALE:1"=2000' APPENDIX F MEETING SUMMARY LETTERS Alaska Energy and Engineering Re:Gustavus Energy Infrastructure Projects 4/15/04 Trip Report &Preliminary Recommendations On Thursday April 14,2005,David Lockard of the Alaska Energy Authority /Rural Energy Group (AEA/REG)and John Dickerson of Alaska Energy and Engineering (AE&E)traveled to Gustavus.The purpose of our site visit was to meet with local residents to identify and discuss potential energy infrastructure projects within the community as well as to gather reconnaissance level information for preparation of a Conceptual Design Report (CDR)for any identified projects. We arrived in Gustavus by plane around 6 PM.The next morning at 8 AM we met with Gustavus Mayor Sandi Marchbanks and Richard Levitt,owner of local power utility Gustavus Electric Company and local fuel supplier Gustavus Dray,Inc.Much of the meeting was spent discussing the status and potential future impact of the proposed Falls Creek hydroelectric project.David Lockard also discussed the AEA/REG tural energy programs as well:as Denali Commission (DC)funding requirements.After the meeting Mr.Levitt gave us a tour of the power plant,bulk fuel storage facilities,City dock and gas station. The following summary report is based on information gathered during this site visit.It includes information and preliminary recommendations on: 1)Proposed Falls Creek Hydroelectric Project and Area Power Distribution 2)Existing GEC power plant 3)Proposed new modular power plant 4)Existing bulk fuel storage facility 5)Required fuel capacity 6)Proposed new tank farm 7)Proposed new marine dispensing facility 8)Existing gas station and proposed upgrades 9)Alternative energy This report along with comments from project participants will be the basis for the CDR. 1)Status of Falls Creek Hydroelectric Project and Area Power Distribution: The proposed Falls Creek hydroelectric project is the result of a long term effort by Gustavus Electric Company (GEC)owner Richard Levitt and the community of Gustavus.The proposed project is currently fully designed and permitted.At the time of our site visit the only remaining issues preventing construction of the project were a possible court action by the Sierra Club and ongoing efforts by Gustavus Electric Company (GEC)to secure additional grant funds for construction.The current design is for an 800kW system that is expected to provide approximately 92%of community electrical needs over the next 10 years. The GEC currently serves approximately 200 customers in Gustavus with an annual average load of around 200kW and a peak load of around 350kW.The National Park Service's (NPS)Glacier Bay National Park and Preserve facility at Bartlett Cove is Gustavus Energy Infrastructure Projects Preliminary Recommendations approximately ten miles from Gustavus.The NPS facility is not currently connected to the GEC grid.The NPS power generation and distribution system has a peak annual load of approximately 160kW. D.Hittle &Associates recently prepared a report for the NPS analyzing the long termcostofselfgeneratingversusthecostofpurchasingpowerfromGECassumingthat the Falls Creek hydro project is constructed.The report concludes that the most cost effective option will be to connect to the GEC grid.However,at this time there have been no direct negotiations between GEC and NPS regarding a future power agreement., There is currently no design or funding for either a line extension from Gustavus to the NPS facility at Bartlett Cove or for paralleling switchgear to integrate hydroelectric power into the current GEC generation/distribution system.Based on the assumption that the hydro system will be constructed and the NPS will opt to connect to the GEC grid,it is our recommendation to include a conceptual design and cost estimate for the required switchgear upgrades and NPS line extension as part of the Gustavus EnergyInfrastructureUpgradeProjectCDR.Additional proposed power distribution upgrades include a new step-up transformer bank as well as an approximate one mile extension of buried distribution to the proposed new tank farm site and new marine fueling facility at the city dock. 2)Status of Existing GEC Power Plant: The existing Gustavus power plant is owned by GEC.It is located on a 65'x150'lot on the east side of the paved road near the airport.The building is of metal-sided,pre- engineered steel frame construction with concrete foundation and measures approximately 30'x40".It is over twenty years old and is in fair overall condition. There are four generators installed in the power plant.Unit #1 is a 250kW Cummins KTA19-G2,unit #2 is a 300kW Caterpillar D353E-TC,unit #3 is a 100kW Caterpillar D342-6 and unit #4 is a 500kW Cummins VTA12-800GS.Unit #1 has over 30,000 total hours.Units #2 and #3 are antiquated models that are no longer in production.Unit #4 was purchased used several years ago and is seldom in service as it is somewhat oversized for existing community loads. Generators #1 and #3 are on a common Cooling manifold with two remote radiators. Generator #2 has a skid-mounted radiator with belt-driven fan.Generator #4 is on a stand-alone cooling system with one remote radiator. Power generation from unit #1 is at 480V 3-phase,which is then stepped up to 2,400 volts through an exterior transformer bank prior to being routed to the switchgear.Power generation from units #2 through #4 is at 2,400V 3-phase.There is a 7,200Vdistributionstep-up transformer bank within the fenced area adjacent to the power plant.|The manual paralleling switchgear is a combination of cabinets of various makes and models that were purchased used and field modified as needed for installation. 3)Description of Proposed New Modular Power Plant: It is our recommendation that the existing power plant be abandoned and replaced with a new modular power plant.The preferred location for the new power plant is on the same lot and behind the existing power plant building.The new facility will contain four generators sized in combination to meet peak community loads,including an allowance Page 2 of 6 Gustavus Energy Infrastructure Projects Preliminary Recommendations for near term future growth,as well as to efficiently meet anticipated peak-adding loads for augmenting hydroelectric power when required.The proposed generation capacitywillnotincludetheanticipatedNPSBartlettCovefacilitydemandbecauseitisassumed that Bartlett Cove would revert to self generation if hydroelectric power was offline for any reason.Power monitoring and recording equipment should be installed in the existing power plant as soon as possible in order to more accurately determine the electrical demand profile for the community.The proposed power plant will also include 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 16'W x 50'L modular skid-mounted building. 4)Existing Bulk Fuel Storage Facility: The Gustavus Dray,Inc.bulk fuel storage facility is owned by Richard Levitt and is located on the east side of the paved road near the city dock.The tank farm is used for storing virtually all of the #1 diesel,#2 diesel,unleaded gasoline and avgas imported into Gustavus.The facility consists of a two product marine header,two buried bargefillpipelines,five vertical steel storage tanks,three single-wall horizontal steel storagetanksandbulktransfer(truck loading)hose connections for four products.The fuel is used for community power generation and local heating fuel deliveries as well as retail dispensing at the gas station and airport. The total gross shell capacity of the tanks is approximately 47,500 gallons of #2 diesel, 20,000 gallons of #1 diesel,20,000 gallons of unleaded gasoline,10,000 gallons ofavgasand7,500 gallons of switch-loading capacity that is #1 diesel in the winter and unleaded gasoline in the summer.The vertical tanks are older BIA style tanks.All of the tanks appear to be well maintained,with mostly good paint except for some small areas of loose paint and surface rust.The tanks are all equipped with normal vents and threaded bottom connections.The vertical tanks have manways but there are no manholes on the horizontal tanks.None of the tanks are equipped with emergencyvents.The manifold piping is a combination of welded and threaded steel fittings with no flexes or pressure relief valves. The tanks are contained within a lined 74'long x 38'wide concrete dike.There is a 6' high chain link security fence around the perimeter of the dike.There is currently no electrical service to the tank farm so there is no area lighting.Truck filling is by gravityortruck-mounted pump.There is no truck fill area secondary containment. There are two 3"diameter welded steel barge fill pipelines that are buried from the tank farm to the dock and are supported above grade on the dock.There is no cathodic protection of the buried pipelines.One of the pipelines is used for #1 and #2 diesel while the other is used for unleaded gasoline and avgas.The pipelines are blown out between fuels and after all deliveries.A two product marine header is located near the end of the dock.Both barge connections have a 3"quick disconnect hose coupling,a 3"flanged steel check valve,and a 3"flanged steel plug valve.There is a singlealuminumdrippanthatdoesnothaveadequatecapacitytomeetthe84gallon containment requirement. This facility does not meet current code or regulation requirements and would not to be cost effective to renovate.A complete list of deficiencies will be included in the Concept Design Report.Therefore it is our recommendation that the tank farm be Page 3 of 6 Gustavus Energy Infrastructure Projects Preliminary Recommendations taken out of service and replaced with a new tank farm located on or near the same property. 5)Required Fuel Storage: Gustavus is located on a year round ice free port with a deep water dock capable of receiving ocean-going barges.Fuel deliveries by barge are available from two different vendors and are scheduled to be in the area at least once per month.According to fuel delivery records,the community has recently averaged approximately eight bargedeliveriesperyear,spaced from one month to two months apart.At least one of the major fuel barge delivery services offers a $0.05 discount on fuel when the total!quantityofallproductsdeliveredpertripexceeds20,000 gallons.Based on this deliveryscheduleandpricestructure,we have opted to size the facility to hold an approximate two peak months supply of each product and to have around 20,000 gallons of total available capacity per scheduled delivery with an adequate reserve margin.The following table compares the current annual and 2 month use for each product to the proposed net useable tank capacity for the new facility: CONSUMPTION VERSUS CAPACITY Product |Average |Estimated |Proposed |%of Est.|%of ProposedAnnualPeak2NetPeak2°|Est.Gross Use in Month Capacity Month Annual |Capacity inGallons|Use in in Gallons |Use Use Gallons (1)Gallons (2) Gasoline |140,000 40,000 48,600 121%-35%54,000 Av Gas 15,000 7,500 9,000 120%60%10,000 #1 Diesel |86,000 25,000 27,000 108%31%30,000 #2 Diesel |225,000 50,000 54,000 -108%24%60,000 Total |466,000 144,000 160,000 (1)Calendar years 2001 through 2004. (2)Net capacity (90%of gross shell capacity) 6)Proposed New Tank Farm: The proposed new tank farm will include two each 30,000 gallon #2 diesel tanks,one 30,000 gallon #1 diesel tank and two each 27,000 gallon gasoline tanks.One of the #2 diesel tanks,one of the gasoline tanks and the #1 diesel tank will have 10,000 gallon partitions for the proposed new marine dispensing facility.There will also be one 10,000 gallon avgas tank.The tanks will all be horizontal skid-mounted single wall welded steel tanks.Secondary containment will be provided by a lined heavy timber constructed dike.A truck loading facility with secondary containment will be constructed adjacent to the dike. Four new 3”diameter pipelines will be installed,one for gasoline,one for #1 diesel,one for #2 diesel and one for avgas.The gasoline,#2 diesel and #1 diesel pipelines will be equipped with valves to allow them to serve as fill pipelines for barge deliveries and as distribution pipelines for marine dispensing.The pipelines will be buried from the dock to the new tank farm.A drip pan will be provided on the dock at the termination of the Page 4 of 6 Gustavus Energy Infrastructure Projects Preliminary Recommendations fill pipelines (marine header).Three of the new pipelines will have branch tees with isolation valves to serve the dispensers on the dock.A combination of centrifugal andsubmersiblepumpswillbeusedfortruckfill,bulk transfer and marine dispensingfunctions. 7)Proposed New Marine Dispensing Facility: There are many private boat owners,sport fishing charter operators as well as a few remaining commercial fishermen operating out of Gustavus.There is no local boat harbor so that during the summer boating season as many as sixty vessels may bemooredintheareanearthecitydockatanygiventime.The nearest marine dispensing facility is at the NPS Bartlett Cove dock,a distance of approximately 15mileseachwaybyboat.Therefore most local boat owners opt to fuel their vessels from the city dock using pickup truck mounted fuel tanks.Because of the long,narrow dock access ramp and limited space available on the dock,this activity can cause extreme congestion during the busy summer tourist season. Due to the inconvenience and inherent risks associated with this current method of fueling vessels,there is strong public support for a marine dispensing facility.However,the State Fire Marshall has denied a previous permit application to install fuelingequipmentonthedockduetheInternationalFireCode(IFC)requirement that marine dispensing must be from a dedicated dock or float.The installation of additional pilingsoffthewestfaceofthecitydocktosupportadedicatedplatformandfloatonwhichto mount a marine dispensing facility may be required in order to meet this code requirement. It is therefore our recommendation to include a conceptual design and cost estimate for a new marine dispensing facility at the city dock in the CDR.However,the new pile supported dock extension and float on which the dispensing facility would be placed must be provided to the project by the community due to the funding constraints of this program. 8)Existing Gas Station and Proposed Upgrades: The Gustavus Dray,Inc.gas station is owned by Richard Levitt.The facility is located at the intersection of the airport and dock roads in the center of the townsite. There are three unique renovated antique dispensers,one for gasoline,one for #2 diesel and one for #1 diesel.The dispensers have been modified for use with remote pumps and electronic pulsers.All three are integrated into a card swipe system with remote monitor located inside the gas station building.The dispensing portion of the gas station appears to be fully code compliant with all required appurtenances including shear valves at the dispenser bases,hose breakaways,automatic shut-off nozzles and an emergency stop switch located on the corner of the building.. The gas station tank farm consists of three buried 1-1/2"distribution pipelines and three each 2,800 gallon single-wall horizontal steel dispensing tanks with submersible dispensing pumps.The tanks are in poor condition with large areas of loose paint and . surface rust.The tanks rest directly on the dike floor and are braced by wooden cribbing.Two of the tanks are equipped with emergency vents and manholes but the third tank has neither.The manifold piping is a combination of welded and threaded steel and brass fittings and valves with no flexes or pressure relief valves.The tanks are contained within a lined earthen pit.There is a combination chain link and wood Page 5 of 6 Gustavus Energy Infrastructure Projects Preliminary Recommendations stave fence around the perimeter of the dike that is less than 6'high.Tank filling is from tanker and tank truck by gravity or truck-mounted pump.There is no truck fill area secondary containment.There is no cathodic protection on the buried steel distribution pipelines.. The gas station tank farm does not meet current code or regulation requirements and would not to be cost effective to renovate.A complete list of deficiencies will be included in the Concept Design Report.Therefore it is our recommendation that the gas station tank farm be taken out of service and replaced with new dispensing tanks and distribution pipelines located on the same property. 9)Alternative Energy: Except for the proposed switchgear upgrades at the power plant and the NPS intertie, the Falls Creek hydroelectric generation and intertie project is not within the scope of this project. There are no identified facilities,such as a school or public building,within a practical distance of the power plant location that could benefit from recovered engine heat; therefore,no heat recovery equipment is proposed for the power plant module.No other potential alternative energy projects have been identified for Gustavus. Please review the issues presented and call David Lockard at 269-4541 to discuss or fax your comments to 269-3044.In order to keep the CDR on schedule we need to receive all community comments no later than July 1,2004.|look forward to working with you on this project.
