On Wednesday August 13,2003,David Lockard of the Alaska Energy Authority /Rural Energy Group (AEA/REG)and John Dickerson of Alaska Energy andEngineering(AE&E)performed a site investigation for a proposed new bulk fuelupgradeprojectinNanwalek.A meeting was held with local residents andcommunityleaderstodiscusstheproject. The new Village tank farm will provide storage for virtually all of the gasoline anddieselfuelrequiredforretailsales,public building heating,and heavy equipmentoperationinalinedearthenbermdike.A single product dispenser equipped with amagneticstripedebitcardaccessinventorycontrolsystemwillbeinstalledwestoftheconsolidatedtankfarmadjacenttoAlexandrovskyRoad.A bulk transfer facilitywillbeconstructedwithinthecontainmentdikeforreceivingtruckdeliveriesofdieselandgasolineandforfillingfueltrucksandportabletankswithdiesel.A securityfencewillenclosethedikeandbulktransferarea. One existing 550 gallon tank will be taken out of service at the NPRHA complex.New buried fuel distribution piping will be installed from the remaining two 550 gallontankstotheNPRHAofficeandapartmentbuildings. The proposed project schedule calls for design and permitting to be completed bythewinterof2003/2004,construction from June through August 2004,and thefacilityfullyfunctionalbySeptember2004. There are no existing village tanks suitable for re-use.Two new tanks will be required to meet the projected fuel storage requirements for the community.Theconsolidatedtankfarmwillhaveagrossstorage(tank shell)capacity of 27,000gallonsofdieselfueland12,000 gallons of unleaded gasoline.The tank farmprovidesacombinednetstoragecapacityof35,100 gallons based on 90%of the gross capacity. The total project cost including all design,supervision,inspection,permitting,and a15%contingency is estimated to be $698,104,which equates to a unit cost of $17.90 per gallon based on a gross storage capacity of 39,000 gallons.This is within theDenaliCommissionbenchmarkcostrangeof$18 to $14 per gallon for 0 to 50,000galloncapacitytankfarms.

purposeofthisstudyistoprovideaconceptdesignandconstructioncostestimateforconsolidationandupgradeofallpublicdieselfuelandgasolinestorageinthecommunityofNanwalek.For the purpose of this study,the term "diesel fuel'refers to all fuel oil products used for space heating and heavy equipment operation.There is no diesel fuel consumption in Nanwalek for school heat orforpowergenerationbecausetheschooliscurrentlyheatedwithpropaneand'the community is served by an intertie from the Homer Electric Associationpowergrid.The Nanwalek IRA Council (Village)and the North Pacific RimHousingAuthority(NPRHA)are the only participants in the project. 1.1.Program Overview The Alaska Energy Authority (AEA),Rural Energy Group is pursuing grant funds to upgrade rural bulk fuel tank farms.Following is a brief outline of the program: e Most of the funds are federal and provided through the Denali Commission.Other federal funding may be available from HUD (ICDBG)and theEnvironmentalProtectionAgency(EPA).Additional funds may be available from the State of Alaska,through the Department of EnvironmentalConservationandtheDepartmentofEducation. e In order to receive grant funds,each community must demonstrate that the proposed facility will be sustainable by accepting a business plan.Thebusinessplanshalldescribewhowillownthefacility,and how it will beoperated,maintained and replaced. e New tank farms 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 toselectasiteforthenewtankfarm. e At the completion of Phase 1 Conceptual Design,the community will berequestedtoreviewandapprovethelocationofthetankfarm,the number and volume of fuel tanks,and a draft business plan. e During Phase 2,Design Completion,the design for the new tank farm 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 byprovidingthelandforthenewtankfarmandfreeuseoflocalheavyequipment.The grant funds pay for equipment fuel,maintenance,and repairs of equipment during construction. e Project may include local hire and construction trade training programs, subject to Denali Commission funding. e If construction funding is awarded then the business plan will be sent forsignatureandconstructionprocurementwillstart. e Ineligible Projects:Funding is not available through AEA for buildings,propane facilities,fuel tank trucks or trailers,fuel to fill the tank farm, Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Design Report Alaska Eneray and Engineering operation and maintenance costs,or residential tank upgrades.Loans forfueltanktrucksandtrailersmaybeavailablethroughUSDA. e Training Available:AEA has several training programs available forcommunities. 1.2 Community Description Nanwalek is located on the southern

acodeevaluationofexistingfacilitiesandpreparationofadatabasesummarizingresults.The existing NPRHA facility,the only existing facility that meets the EPAregulatorythresholdof1,320 gallons,was reviewed and information in the database verified.The following is a summary of existing facility deficiencies observed: e Improper Secondary Containment (Diking)-Tanks are not within a properliquidtightsecondarycontainmentsystemofadequatecapacityasrequiredbytheFireCodeandEPAregulationsandsomeofthetankshavenocontainment. e No Security Fence -Tanks are currently accessible to the general public withnosecurityfencing.This presents a hazard to the community as well asincreasingthechanceofaspillorfireduetovandalismandtheft. e Improper Piping and Valves -Existing piping systems consist of above andbelowgradecoppertubing.The threaded flare fitting joints are particularlypronetoleaking. The combination of these deficiencies and the use of unregulated small tanks inthecommunityaswellastheoldvillagefueltruckforfuelstorageposeasignificantthreattopublicsafetyandtheenvironment.A major project isrequiredtoconstructanewcodeandregulationcomplianttankfarmtomeetthelong-term needs of Nanwalek. The concept design for the new facility has been prepared to meet current codeandregulatoryrequirementswhichinclude: e The 2000 Edition of the International Fire Code,including State of AlaskaAmendments e The 2002 Edition of the National Electrical Code e 40 CFR,Part 112.1-12,U.S.Environmental Protection Agency SpillPreventionRequirements e 33 CFR,Part 154.30 &154.1030,U.S.Coast Guard Spill PreventionRequirements The design also incorporates appropriate industry standards such as NationalFireProtectionAssociation(NFPA)and American Petroleum Institute (API)aswellasprovenmethodsandmaterialsthathavebeenusedsuccessfullyonotherruralbulkfuelfacilitiesinsimilarlocationsandclimates. Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Design Report Alaska Energy and Engineering 2.0 EXISTING FUEL STORAGE FACILITIES -FUNCTION AND CAPACITY The fuel storage situation in Nanwalek is different than most comparable rural communities.Historically there has not been a central bulk fuel storage facility orretailoutletforgasolineordiesel.There is a long history of deliveries of dieselfuelbylandingcraftwitharoll-off tanker truck as well as pre-purchased gasolineindrums.The village currently owns a tanker truck to deliver diesel fuel to residential and public tanks.The only existing facility that exceeds the EPA tankfarmvolumethresholdisthesmallNPRHAfacility.This facility is located nearthecenterofthecommunityattheNPRHAcomplexasshownonattacheddrawingM1.Tank farm numbers below correspond to the numbers assigned intheDOEdatabase.The facility was evaluated to determine specific needs and deficiencies.Tanks were visually examined to determine suitability for re-use.The following paragraphs summarize findings: e Village -Clinic (#1).Renovated -no longer exceeds EPA tank farmthresholdvolume. e NPRHA Complex -(#2).The NPRHA owns and operates three storage tanksthatsupplyheatingfueltothevillagehousingcomplex.These tanks supplyfueltothehousingauthorityoffice,the IRA Council office,a communitywasheteria,and a four unit apartment building.The tanks and buildings arelocatedjustoffHermanStreetnearthecenterofthevillage.The tanks arefilledbythevillagetanktruckviafueldeliveryfromvessel.All tanks aresinglewall,U/L labeled,saddle-mounted,horizontal tanks that appear to beingoodcondition.The three tanks are identical 550 gallon nominal capacitytankslocatedontheeastsideofthecomplex.All tanks are equippedsimilarlywithnormalandemergencyvents,top-mounted level gauge,cappedfillconnectionwithinalockedoverfillbasin,and spare threaded bung.Thetanksaddlesareboltedtoconcretepads.Copper tubing extends from valvesatthebaseofeachtankandbelowgradetothethreehousingunitbuildings.Buried tubing appears to be partially protected within plastic tubing.The tankvalvesandexposedcoppertubingareprotectedby2”x10”timbers.There isnosecurityfencing,lighting,vehicle protection,or secondary containment.Previous leaks have stained the soil beneath the valve on one of the three 550 gallon tanks. e Village -Fuel Truck.Other than the NPRHA complex tank farm,the onlyexistingbulkfuelstorageinNanwalekiswiththeVillageowned2,000 gallontankertruck.The truck is parked on the deck of a beached landing craft inordertoreceivedieselfuel.After all community tanks are filled the tankertruckistypicallytoppedoffagainpriortothelandingcraft's departure toprovidefueltothecommunityuntilthenextbargedelivery.Diesel from theVillagetruckisusedforspaceheatingofallIRACouncilfacilities,includingthecommunitycenterandclinic.It also provides space heat for the localstore,private residences,church,and for operating Village heavy equipment. Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Design Report Alaska Energy and Engineering 2.1.Existing Equipment Suitable for Reuse There are no fuel tanks or equipment available for reuse. 2.2 Demolition of Existing Tanks The scope of this project will also include removal from service of one of thethreeNPRHA550gallontanks.This tank will be drained of product,the pipingwillberemoved,and the tank connections will be plugged or blind flanged.TheabandonedtankwillthenbereturnedtotheNPRHA. 3.0 CURRENT FUEL CONSUMPTION Recent annual fuel use estimates were obtained from the Village and Wel'Aska Inc,owner of the MV Helinka B.The following table summarizes annual consumption and existing storage capacity.All capacities are in gallons.Netcapacityiscalculatedas90%of the tank gross (shell)capacity. CURRENT CONSUMPTION VERSUS EXISTING BULK STORAGE CAPACITY Product Annual Existing Existing Use Net Gross Estimate Capacity |Capacity Community Gasoline 15,000 0 0 Consumption (1) NPRHA ComplexDiesel 3,000 1,485 1,650 Community Diesel Consumption (2)15,000 0 0 Total 33,000 1,485 1,650 (1)Gasoline is used for village pickup trucks,four wheelers,private boats,and for the local commercial salmon set-net fishery.All gasoline is currentlyimportedandstoredindrums.Imports are from landing craft deliveries, local private boats,and fish tenders. (2)All community diesel imports other than NPRHA Complex fuel. 3.1.Planned Infrastructure Improvements It is important to evaluate the impact of recent installations and planned near-term infrastructure improvement projects on existing utility systems.Schooladditions,water and sewer expansions,new homes,as well as other communityimprovementsallcanadverselyimpacttheadequacyofexistingutilities.Planned near term projects that will increase local fuel consumption include 9newhousesandanadditiontothecommunitycenter.The Village IRA Council iscurrentlyattemptingtopersuadetheKenaiPeninsulaBoroughSchoolDistrictto convert the school to oil fired heat due to safety concerns regarding the largeamountofpropanestoredattheschoolinthecenterofthevillage.Additional 5 Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Design Report Alaska Energy and Engineering capacity will be included in the proposed facility to accommodate the school in |case it does convert to diesel fuel.Following is the estimated impact of these projects: e Heating for new homes -3,000 gallon increase in diesel imports. e Heating for new community center -1,000 gallon increase in diesel imports. e School anticipated annual use -10,000 gallons. 3.2 Alternative Energy/Efficiency Improvements The National Renewable Energy Laboratories wind energy atlas suggests thattheremaybeasignificantwindresourcenearNanwalek.Nanwalek is served byanintertiefromtheHomerElectricAssociationpowergrid.Since Homer Electric purchases its power from Chugach Electric,and Chugach Electric has a wind energy development program,there may be an opportunity for the NanwalekTribalCounciltopursuealternativeenergyandlocaljobdevelopmentbyinvestigatingthefeasibilityofawindpowerprojectnearNanwalek.However,due to the reliability and reasonable cost of electricity in Nanwalek,there doesnotappeartobesufficientalternativeenergyorend-use efficiency opportunitiestojustifyreducingthefuelstoragecapacity. 3.3 Tank Capacity Requirements Nanwalek is located on a year round ice-free port with a beach capable ofreceivinglandingcraftdeliveries.Several landing crafts operate out of Homer, approximately 40 miles away.However,due to the lack of any bulk fuel storagewithinthecommunity,landing craft delivery quantities are currently limited to theavailablecapacityofallsmalllocalpublicandresidentialtanksplusamaximumof2,000 gallons (the capacity of the village fuel truck).The approach to thebeachlandingsitefromCookInletisextremelyshallowandcanonlybenegotiatedathightides.This usually requires that the landing craft go dry andremainonthebeachuntilthenexthightideinapproximatelytwelvehourstime.When the round trip travel time from Homer is included,the total barge timerequiredperdeliveryistypicallyclosetotwenty-four hours.Because a landingcraftcannotlegallytransferfuelfromthevesseltoshore,it must be largeenoughtocarryafueltruckondeckortoparkthevillagefueltruckondeck.Daily rates for landing crafts of this size range from $4,000 to $6,000 per day.Due to the low delivery volume,it is currently un-economical for landing craftoperatorstodeliverfueltoNanwalek.Only one operator is currently willing tobringfueltothecommunityandthisistypicallydoneonlywhenthevesselisintheareaforotherworkorwhenthereisalowfuelemergency.Due to the lack offuelstorageinthecommunity,severe fuel shortages can occur when badweatherorvesselschedulingconflictscauseevenashortdelayinthedeliveryoffuel.Based on this delivery method and cost structure,and in order to limit thenumberofdeliveriesrequired,we have opted to size the proposed facility to holdaminimumofsixmonthssupplyofeachproductandtohaveapproximately16,000 gallons of total available capacity per scheduled delivery with anadequatereservemargin.It is necessary to size the tank farm to meet the combined needs of all users with sufficient capacity to accommodate futuregrowth.The following table compares the current annual,projected annual andprojectedsixmonthuseofeachproducttotheproposednetuseabletank'capacity for the new facility: Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Design Report Alaska Energy and Engineering CONSUMPTION VERSUS CAPACITY Product |Current |Future |Future Proposed |%of ProposedEst.Est.Est.6 Net Est.GrossAnnual|Annual |Month Capacity |Future |CapacityUseinUseinUseinin6in Gallons |Gallons |Gallons |Gallons Month |Gallons (1)(2)Use Gasoline |15,000 16,000 8,000 10,800 135%12,000 Diesel 18,000 3 Ned 16,000 24,300 152%27,0003 Project Total 24,000 35,100 146%39,000 (1)Estimated future use based on planned development.

These operating costs will need to be determined on a per gallon of throughputbasis(as part of the required Denali Commission required Facility Business Plan)and the price of fuel adjusted to cover the facility operating costs. 10 Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Design Report Alaska Energy and Engineering 6.0 PERMITTING AND SPILL RESPONSE The new facility will be subject to Regulations of both State and FederalagenciesincludingtheDivisionofGovernmentalCoordination,the Division ofFirePrevention,and the U.S.Environmental Protection Agency.Dependinguponlocalconditions,additional permitting agencies such as the U.S.Fish andWildlifeService,the U.S.Army Corps of Engineers,the State Historic Preservation Office,and the Alaska Department of Natural Resources maybecomeinvolved. 6.1 Environmental Assessment An Environmental Assessment (EA)will be completed prior to construction of the project.An EA is required for all projects that are federally funded or require afederalpermit(such as a Corps of Engineers Wetlands Permit).The EAconfirmsthereisnosignificantimpacttotheenvironmentcausedbytheproject.As part of the EA,a Coastal Zone Management Project Questionnaire will becompletedandsubmittedtotheDivisionofGovernmentalCoordinationandthe Kenai Peninsula Borough.A Corps of Engineers Wetlands permit should not berequiredforthisprojectsinceallworkisbeingperformedonuplandsandnoimprovementswillbeplacedbelowmeanhighwater.However,the need for apermitwillbeinvestigatedfurtherwiththeCorpsofEngineersearlyinthepermittingphase.If required,this project should qualify for review under theDepartmentoftheArmyGeneralPermit96-07 for village bulk fuel facilities.Thegeneralpermitstreamlinestheapprovalprocess.Similar projects have beenpermittedinlessthantwomonthsunderthegeneralpermit. 6.2 Fire Code A Plan Review permit from the State Fire Marshal is required.Final stampeddesigndrawingswillbesubmittedforreviewandapprovalpriortoconstruction.Plans will be reviewed for conformance with the International Fire Code and portions of related codes including the International Building Code and theNationalElectricalCode.In prior years the review process has only taken 3 to 4weeks;however,recent projects have taken over 6 months.Generally site workandmobilizationisallowedtoproceedpriortoapprovalbutthepermitmustbeinplacepriortoplacementoftanksorsimilarinstallation.Plans should be submitted by February 2004 to ensure approval in time for summer 2004 construction. 6.3 Spill Response Because all deliveries will be received by truck (no direct marine deliveries),thenewfacilitywillnotbesubjecttoU.S.Coast Guard regulations and will not require a Facility Response Plan or an Operation Manual.However,since the tank farm has oil storage tanks in excess of 660 gallons,it will be subject to U.S. Environmental Protection Agency regulations and will require preparation of aSpillPreventionControlandCountermeasures(SPCC)plan. Spill response gear including sorbent material and protective safety gear will be purchased and left on-site upon project completion along with a 5,000 gallonfoldableportabletanktoserveasoil-spill contingency storage. 14 Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Desiqn Report Alaska Eneray and Engineering 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 granteeactingastheemployerandutilizingprimarilylocallabor.This method tends toachieveahigherpercentageoflocalhireandisstronglysupportedbymanycommunitiesandfundingagencies.The highly technical nature of tank farmprojectsrequiresalimitednumberofworkerswithspecificexperienceandexpertisetobebroughtinfortheprojectwhennotavailablelocally.All workmustbesupervisedandmanagedbyasuperintendentwithextensiveexperienceintheconstructionofruralfuelfacilities.All specialty work,such as pipe weldingandelectricalinstallationmustbeperformedbyskilledcraftsmenwith appropriate certifications.An experienced construction manager will be requiredtorecruitthenecessaryskilledlabor,coordinate the construction team,andoverseeprocurementandprojectlogistics.The design engineer will providequalitycontrolthroughcommunicationwiththeconstructionmanagerand periodic on-site inspections. 7.1 Local Job Skills An inquiry was made for information regarding the availability of specialty skilledlaborinNanwalek.The following table summarizes the results: Skilled Trades Number Available Certified Welder 0 Welder Helper 2 Journeyman Electrician 0 Electrician Helper 0 Carpenter 0 Heavy Equipment Operator 2 Heavy Equipment Mechanic 0 In addition to the specialty trades listed,there are a number of local residents with general labor experience in various types of construction.It appears that ataminimumaprojectsuperintendent,a pipe welder/mechanical foreman,and ajourneymanelectricianwillneedtobebroughtintoNanwalekforthisproject. 7.2 Local Equipment A preliminary inventory was performed on local heavy equipment in Nanwalek as listed in the following table: Unit Model #Owner/Lessee John Deere Loader with Backhoe 455G IRA Council John Deere Dozer 450G IRA Council Road Grader AK DOT Bobcat Skidsteer,Backhoe.NPRHA The equipment is all in fair condition and should be adequate to perform a portion of the work required.Prior to the start of construction an experiencedfleetservicemechanicwillneedtobesenttoNanwalektogothroughtheequipmentwiththelocalmechanicstoensurethatitisallinproperoperating 12 Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Design Report Alaska Energy and Engineering condition.Additional heavy equipment,including a large loader,a larger dozer,an excavator,dump trucks,and a screen will need to rented and transported to Nanwalek by barge from Seldovia or Homer. 7.3.Material Sources Due to the subsoil conditions,drainage requirements,and surface contour of the proposed tank farm site,as much as 2,000 yards of fill material may be requiredforthisproject.The only existing local borrow site is on a private native allotment located across the English Bay River from the town site.This borrow site has recently been heavily mined for an ANTHC water project and it appears thatmostavailablematerialhasbeentaken.In addition,in order to use the site permits would be required from both the Alaska Department of NaturalResourcestoallowforcrossingtheEnglishBayRiverandfromtheBIAtoallow mining of the native allotment.Due to the probable long time frame required toreceivethepermits,the anticipated restrictions and conditions that would be placed on the project by the permits as well as the limited amount of materiallikelyavailableatthesite,an alternate source of fill material for this project wassought. One alternative investigated is the option to import the required gravel fromHomerorSeldoviabybargeratherthantominealocalsource.Due to theshallowbargelandingareaandtidalaccesslimitations,only around 150 yards ofgravelcouldbedeliveredperday,subject to weather conditions.Due to the highcostoftransportation,barge delivered gravel is likely to approach $75/yard,including equipment time for loading,unloading,and stockpiling. Another option investigated is to develop a borrow source adjacent to theboroughlandfillsiteonthenorthernedgeoftheVillagetownsite.The landfill siteisleasedtotheboroughbytheIRACouncilandallofthelandborderingthesite,including the proposed borrow site,belongs to the IRA Council.PreliminarydiscussionswiththeKenaiPeninsulaBoroughsolidwastedepartmentindicatethattheyarewillingtoallowaccessthroughthelandfilltotheproposedborrowsite.The borough has also indicated an interest in discussing the possibleexpansionofthelandfillleaseboundariestoincludeanynewlevelareathatwouldresultfromtheminingoftheadjacenthillsideforgravel.Samples takenfromtheareaindicatethattheavailablematerialispoorlygradedgravelwithcobbleandsand.A screen plant is available for lease in Seldovia and could be set up on site to provide screened material as necessary.The area to the northofthelandfillisalsoalikelyareafordepositingtheoverburdentoberemoved from the tank farm site as well as from the borrow site.An equipment gate couldbeaddedtonorthernsideofthelandfillsecurityfenceandtheoverburden staged in such a way as to provide an easily accessible source of cover materialforthelandfill.The location of the landfill and proposed borrow site is shown on attached Site Plan sheet M1. 13 Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Design Report Alaska Energy and Engineering 8.0 SCHEDULE Site preparation for this project is considerably more involved and complex incomparisontotherestoftheworkthanwouldnormallybeencounteredonsimilarsizedprojects.Some of the factors contributing to this are: e No existing local borrow source e Large amount of overburden to be removed from the tank farm site e Large amount of fill material required at the tank farm site e Necessity of screening drain rock and gravel cover from local material There is no local equipment that is suitable for this site preparation work.Due totheamountofearthmovingequipmentrequired,the schedule includes aseparatemobilization/demobilization for the site preparation portion of the projectonly.Alternatively,the site preparation portion of the job could be separatedfromtheforce-account tank farm work and bid out to qualified contractors if desired.There are several contractors in the Homer/Seldovia area that have access to the necessary earthmoving equipment,screen plant,and barge,aswellastheexperiencetoperformthesitepreparationportionoftheproject. After the site preparation portion of the project is complete,mobilization of thetankfarmconstructionportionoftheprojectwouldbegin.All required tools,materials and equipment would be staged in Homer and delivered by landingcraftinonetrip.Because the 12,000 gallon fire rated tank will weigh in excess of40,000 Ibs,the initial barge mobilization should include a piece of equipmentcapableofmovingandplacingsuchaheavytank.Since a large excavatorwouldalsobeusefulindevelopingtheborrowsiteandrippinghardpanmaterial,the cost estimate includes a month rental for a Caterpillar 345 class excavator.Since this piece of equipment will no longer be needed after the dike isconstructedandthefireratedtankisset,it may be cost effective to hire alandingcrafttoreturnthispieceofequipmenttoHomerpriortoproject demobilization. The schedule on the following page has been developed on the basis ofperformingthemajorityoftheworkinthesummer.This summer 2004constructionscheduleiscontingentontimelyapprovaloftheplanbytheVillage IRA Council and Denali Commission as well as on funding availability. 14 Nanwalek Bulk Fuel Consolidation &Upgrade November 17,2003 Concept Design Report Alaska Energy and Engineering PROPOSED PROJECT SCHEDULE JANFEBMARAPRMAYJUNJULYAUGSEPOCTPH.Il TASKS (2004) 95%DESIGN Xomn=-X REVIEW &FUNDING Xa-="X FINAL DESIGN X-X PH.Ill TASKS (2004) PERMITTING xX--- ORDER TANKS X--X ORDER REST OF MATL'S X-==X SITE PREP &GRAVEL PAD Xm=X FREIGHT &MOBILIZATION x-x FINISH SITE/DIKE X--X PLACE TANKS x PIPING,DISPENSER,ETC..x--x FENCE,ELECTRICAL,ETC.x=X RECEIVE FUEL X-X PUNCH LIST COMPLETION x-X SPILL PLANS &CLOSE OUT oo =X 9.0 COST ESTIMATE The construction cost estimates have been developed based on a "modified"force-account approach utilizing a combination of local labor,certified craftsmen, and specialty sub-contractors under the direction of an experienced constructionmanager.Labor rates are based on Title 36 equivalent wages for certifiedspecialtylaborandprevailinglocalforce-account wage rates for general laborandequipmentoperation.A detailed cost estimate is included in Appendix B.The total project cost including all design,supervision,inspection,permitting,anda15%contingency is estimated to be: e $698,104 (39,000 gallons at $17.90/gallon) The unit cost of $17.90/gallon is within the Denali Commission benchmark costrangeof$18 to $14 per gallon for 0 to 50,000 gallon capacity tank farms. 15 APPENDIX A CONCEPT DESIGN DRAWINGS PROPOSED OVERBURDEN/COVER MATERIAL STOCKPILE AREA BOROUGH LANDFILL SITE PROPOSED BORROW SITEfaa NPRHA COMPLEX SITE t KACHEMAK BAY 7 BARGE LANDING -> VILLAGE TANK FARM SITE -SEE SHEET M2 PROJECT:DRAWN BY:JTD SCAE:1°=400"be &of Comsttt,°F,jakeNANWALEKBULKFUELSTORAGEUPGRADEDESIGNEDBy:BCG owe 11-17-03 |*partmen omNDEA/AEA Development TITLE:FILE NAME SHEET OF PF nN aural Energy Group |7S ALASKACOMMUNITYSITEPLANNANW-coR-MIIMA 5 ars et Neer Lateoe.Maasaa ELECTRIC UTILITY US SURVEY 4901 |TRANSFORMER BLOCK 12 LIMIT OF EXCAVATION -SEE tors |ors i EXCAVATION PLAN SHEET M3 ior 7 or4 |LOT 3 -”----/:-oT 2 lor1s| 2”ABOVEGRADE 6'HIGH CHAINGASOLINEOPENDRAINAGE-LINK FENCE PIPELINE CHANNEL,TYP \TO __ DISPENSER!_- .

P.O.Box 111405 Anchorage,AK 99511-1405 ATTENTION:Mr.John Dickerson RE:Subsurface Soil and Foundation Conditions Nanwalek Bulk Fuel Storage Consolidation &Upgrade Lots 2 &3,Block 12,Tract A,U.S.Survey 4901,Townsite of English Bay Nanwalek,Alaska Our Job 03-313.14 Dear Mr.Dickerson: Pursuant to your request,we have completed an evaluation of the subsurface soils and foundation conditions for new bulk fuel tanks and containment berms at the referenced site.This letter is intended to summarize our findings and recommendations for the construction of the bulk fuel upgrade and to transmit the test pit logs along with associated laboratory test data. Attached are a site plan (as prepared by your office)Plates M1 and M2,the four test pit logs,six soil particle size distribution reports,and keys to the symbols and terminology used to describe the soils. Mr.Will Webb,E.I-T.of this firm and you,representing Alaska Energy and Engineering,Inc. (AE&ED)traveled to Nanwalek,Alaska on October 7,2003 via Era Aviation and Smokey Bay Air to evaluate the proposed site.The community of Nanwalek is located approximately 140 miles southwest of Anchorage on the south shore of Kachemak Bay.A total of four test pits were dug using a John Deere 455C track mounted dozer with a backhoe attachment.The pits were dug on the boundaries of the proposed tank farm "foot print”(location).Test pits were located so as not to conflict with the actual tank foundations as disturbed soils would have to be carefully recompacted to correct the damage caused by the test pits.The walls of the pits were logged and samples obtained from the excavations by Mr.Webb.The soil samples were then returned to our Anchorage laboratory for visual examination and testing.Testing included moisture content, organics,and soil particle size. Page 2 AEEI 03-313.14 October 31,2003 Nanwalek Bulk Fuel Storage Upgrade Mr.John Dickerson of AE&EI made a subsequent visit to Nanwalek to obtain additional soil samples for structural fill from a site near the town landfill.These were also analyzed for this report. The site is located on Alexandrovsky Street in the southern end of the town.Vegetation in the immediate area consists of peat,spruce forest,and stands of alder.The site slopes to the southwest at 3 to 5 percent and is essentially flat.A small stream runs approximately down the lot line between Lots 2 and 3,and some surface water was running southeast across the front of Lot 3.In addition,ditches have been cut along the rear property lines on both lots in an attempt to drain the area.The surface water running across Lot 3 is most likely seasonal.An area (approximately 75'by 75')at the southwest end of the proposed tank farm location (outside of the actual facility)appears to have been filled with Sandy Gravel.A Gravel berm or driveway has been constructed on Lot 2 along the property line shared with Lot 3. The US Army Corps of Engineers lists no threat of flood in Nanwalek,but a 20-foot tsunami was recorded in 1883 ("Alaskan Communities Flood Hazard Data 2000”,US ACE).The Environmental Atlas of Alaska,1979 edition,reports design snow and wind loadings of 40 and 30 pounds per square foot,respectively.We do not expect permafrost at this particular site.The mean annual air temperature is between 35 and 40 °F with a mean annual precipitation of 34.9 inches.IBC 2000 seismic coefficients are Ss of 145.8%gravity S;of 55.0%gravity with a site classification of C.The design wind speed is 130 miles per hour,Exposure C. The soil profile in Test Pit 1 consists of Peat to a depth of 7 feet,which is underlain by Gravel with Sand to the limited 8.5 foot depth of exploration.Test Pit 2 was located on the edge ofa fill pad,of which the fill extends to a depth of 1.5 feet.The fill is underlain by a root mat and Organic Silt (OL)to a depth of 4 feet,below which is a 1 foot layer of Gravelly Sand (GM) underlain by a very soft Organic Silt (OL).The soil profiles below the surface organics and fill in Test Pits 3 and 4 consist of relatively clean Gravel with Sand (GW).The Gravel soils will provide an excellent bearing media for tank foundations and containment berms.Water seepage was observed in Test Pits 1,2,and 3 between 4 and 4.5 feet below the surface.The test pit logs are shown on Plates 3,4,5,and 6.Associated laboratory testing results are shown on the test pit logs opposite the corresponding depths of excavation and on the soil particle size distribution reports on Plates 7,8,9 and 10.Symbols and Terminology used to describe the soils are shown on Plates 13 and 14. The underlying Gravels on this site appear to be slope or Talus from higher elevations and have water contents ranging from 11 to 18 percent.In Test Hole 3,the Organic Silt encountered at the bottom of the excavation had a moisture content of 147 percent and an organic content of 19.6 percent. Page 3 AEE]03-313.14 October 31,2003 Nanwalek Bulk Fuel Storage Upgrade FOUDATION RECOMMENDATIONS Based on our work,the site should provide a satisfactory location for the proposed bulk fuel storage facility.Subsurface granular soils will provide a good bearing media when prepared to the following recommendations.Structural fills,of material sampled from the land fill,are expected to undergo minimal seasonal frost volume changes when freezing in the presence of available water,i.e.frost heave.Near surface site soils are not liquefiable in a seismic event and slope stability and land spreading and/or lurching are not expected to be an issue. All organic soils (Peat,organic silt,etc.)and buried debris should be removed from all bearing areas.Since this site appears to be a relict coastal beach at one time,substantial excavation may be required to remove isolated,deeper pockets of Organic Silt (OL)as noted in Test Pit #3,from bearing areas.It is recommended that all new installations be supported on structural fill soils similar to those tested from the land fill site.The allowable soil bearing capacity of the compacted structural embankments may be proportioned at two thousand-five hundred (2,500) pounds per square foot for combined dead and live loadings.This value may be increased by one-third for transient loads such as those associated with wind and seismic action.Exposed subgrades supporting the new installations should be compacted (to correct for excavation disturbance)to 95 percent of the maximum density for that material as determined by the ASTM D-1557 or the equivalent AASHTO T-180 specifications.Additional structural fills are to be placed in maximum one-foot lifts and compacted to a minimum density of 95 percent of the maximum density for that material as above. The particle size distribution reports for the structural fill samples you provided our office are included as Plates 11 and 12.The finer grained material may be used as a structural fill for this project,provided it is capped with a minimum of 12 inches of the courser material.Driveways and non structural pads could be constructed on a filter fabric overlying the natural ground surface (brush removed)with 2 feet of this fill,Nominal compaction (90 %)is desired in these areas. Due to surface and ground water on and around this site,drainage ditches will need to be built to direct runoff away from the tank structures.These ditches should be constructed to direct runoff from the back of the site to the front of the site and under Alexandrovsky Street on both the northwest and southeast ends of the site to form a "horseshoe”around the tank structures.The invert of the ditches should be at or near the elevation of the bottom of the structural fills (3 to 4 feet below existing grades/bottom of organics).Drainages structures (18 inch diameter culverts) across Alexandrovsky Street should be provided with 2 feet of cover.Ditches should be lined with filter fabric and covered with 12-inches of course aggregate (+2-inch material),such as that from the landfill area to prevent erosion.The ditches should be graded to a minimum slope of 1.5 percent. Page 4 AEE]!03-313.14 October 31,2003 Nanwalek Bulk Fuel Storage Upgrade Mechanical piping built in conjunction with this project should also be built on organic free subgrades,such as the existing Gravel (GW)soils and/or on imported borrow material.In any event,you may need to consider flexible piping connections capable of tolerating at least 6 inches of unforeseen differential movement. We appreciate this opportunity to be of continued service.Please do not hesitate to call if you have any questions or we can be of further assistance.

All Denali Commission funded community bulk fuel storage projects costing over $500,000 are required to have a business plan approved by the community.Requirements of the business plan include a surcharge on fuel adequate tocreateafundforrenewalandreplacementoverthelifeofthefacility.Thisdirectlytiesthelong-term operational cost of the facility to the initial constructioncost.This is another reason to carefully define a project that meets the long-term needs of the community without excess costly features. The village (or other operating entity)will also need to add a surcharge on fuel tocoverthecostsofoperatingthenewfacility.Some of the costs associated with operating a tank farm include insurance premiums,bookkeeping,bill collection,electricity,maintenance supplies,and labor.For a facility with very small annualsalesvolume,the per gallon surcharge required to cover costs can be very high.For example,at the current estimated annual consumption of 33,000 gallons(diesel and gasoline combined),a total annual operating budget of $10,000wouldrequireasurchargeof33centspergallontocovercosts.Some of the operating expenses can be reduced or eliminated by adding these duties toexistingjobs.Volunteer labor can also be utilized to reduce costs,as has been done in the past.However,some costs,such as insurance premiums,will beunavoidable.Savings will likely occur due to the increased quantities for eachfuelpurchaseanddeliverybutthesesavingswillbeoffsetbycostsofoperatingandmaintainingthenewtankfarm.The convenience and improvedenvironmentalsafetyassociatedwiththenewfacilitywillmostlikelybeaccompaniedbyanincreaseinfuelpricesinthecommunity. 2)Anticipated Tank Capacity Requirements Diesel fuel is used for space heating of the community center,Village office,clinic,private residences,church,and housing authority office complex as wellasforoperatingheavyequipment.There is no diesel fuel consumption for localpowergenerationbecauseNanwalekisservedbyanintertiefromtheHomerElectricAssociationpowergrid.The school building is currently heated withpropane.Gasoline is used for village pickup trucks,four wheelers,private boats,and for the local commercial salmon set-net fishery.Current consumptionquantitiesarebasedonestimatesobtainedduringthesitevisitcommunitymeeting. Planned near term projects that will increase local fuel consumption include 9newhousesandanadditiontothecommunitycenter.The Village IRA Council iscurrentlyattemptingtopersuadetheKenaiPeninsulaBoroughSchoolDistricttoconverttheschooltooilfiredheatduetosafetyconcernsregardingthelargeamountofpropanestoredattheschool.Additional capacity will be included intheproposedfacilitytoaccommodatetheschoolincaseitdoesconverttodiesel fuel. Nanwalek is located on a year round ice-free port with a beach capable ofreceivinglandingcraftdeliveries.Several landing crafts operate out of Homer,approximately 40 miles away.However,due to the lack of any bulk fuel storagewithinthecommunity,landing craft deliveries are currently limited to a maximumof2,000 gallons (the capacity of the village fuel truck).The approach to thebeachlandingsitefromCookInletisextremelyshallowandcanonlybenegotiatedathightides.This usually requires that the landing craft go dry andremainonthebeachuntilthenexthightideinapproximatelytwelvehourstime. When the round trip travel time from Homer is included,the total barge timerequiredperdeliveryistypicallyclosetotwenty-four hours.Because a landing Page 2 of 4 Nanwalek Bulk Fuel Upgrade Site Investigation Summary &Project Scope - craft can not legally transfer fuel from the vessel to shore,it must be largeenoughtocarryafueltruckondeckortoparkthevillagefueltruckondeck.Daily rates for landing crafts of this size range from $4,000 to $6,000 per day.Due to the low delivery volume,it is currently un-economical for landing craftoperatorstodeliverfueltoNanwalek.Only one operator is currently willing tobringfueltothecommunityandthisistypicallydoneonlywhenthevesselisintheareaforotherworkorwhenthereisalowfuelemergency.Based on this. delivery method and price structure,and in order to limit the number of deliveriesrequired,we have opted to size the proposed facility to hold a minimum of sixmonthssupplyofeachproductandtohaveatleast16,000 gallons.of totalavailablecapacityperscheduleddeliverywithanadequatereservemargin.It isnecessarytosizethetankfarmtomeetthecombinedneedsofalluserswith sufficient capacity to accommodate future growth.The following table comparesthecurrentannual,projected annual,and projected six month use of eachproducttotheproposednetuseabletankcapacityforthenewfacility: CONSUMPTION VERSUS CAPACITY Product |Current |Future'|Future Proposed |%of ProposedAnnualEst.Est.6 Net Est.GrossUseinAnnual|Month Capacity |Future |CapacityGallons|Usein Use in in 6 in (Prelim.|Gallons |Gallons |Gallons Month |GallonsEst.)(1)(2)Use Gasoline |15,000 16,000 8,000 10,800 135%tay(3)3 Village 18,000 32,000 16,000 24,300 152%27,000 and (4) Resident ial #1 Diesel Project Total 24,000 35,100 146%39,000 (1)Estimated future use based on planned development. (2)Net capacity (90%of gross shell capacity) (3)Includes the bulk storage tank and fire rated dispensing tank. (4)Includes 4,000 gallons for infrastructure growth and the School's possibleanticipatedannualuseofapproximately10,000 gallons. 3)Site Location There is very little public land available in the community and options for locating the tank farm are limited.The best option appears to be a site comprised of townsite survey lots 2 &3,Block 12,Tract A.According to NPRHA Executive Director Olen Harris these lots have not been used for a house site due to their somewhat irregular grade and past drainage problems.A recently installed drainage ditch appears to have dried the area considerably.A geotechnical investigation and topographic survey will need to be performed in order to determine if the site is suitable for construction.The project location is shown on the attached Site Plan sheet M1. Page 3 of 4 Nanwalek Bulk Fuel Upgrade Site Investigation Summary &Project Scope 4)Description of Consolidated Facility A 27,000 gallon single wall diesel bulk storage tank,a 10,000 gallon single wall gasoline bulk storage tank,and an existing 2,000 gallon fire rated gasoline dispensing tank would be installed in a lined earthen berm containment dike.A truck loading facility would be constructed adjacent to the dike for receiving deliveries of gasoline and diesel fuel and for loading diesel fuel into the local fuel delivery truck.Secondary containment for the truck loading area would be provided by an extension of the tank farm dike liner and earthen berm dike.The entire containment dike would be sub excavated so that the floor of the dike would be approximately 2'below surrounding grade.This would be done to minimize the amount of gravel fill required and to allow the truck fill area to drain into the dike. A service station style gasoline dispenser would be installed in a security enclosure.A pre-paid debit card based inventory control system would be installed to allow local residents access to gasoline without requiring a Village employee to oversee sales. The facility layout is shown on the attached Tank Farm Plan sheet M2. 5)Local Gravel Source and Alternatives It may be possible to obtain the required permitting to mine gravel from a private allotment owned by Village Council member James Kavasnikof.However, permitting for this gravel source has been difficult to obtain in the past due to the fact that trucks and equipment must cross a salmon stream to access the site. This requires approval from both DNR and Fish &Game.In addition,access is limited to the months between October and March to minimize impact on the salmon run. Depending on the subsoil conditions and surface contour of the proposed tank farm site,as little as 500 yards of gravel may be required for this project.In this case,it may be more cost effective to import the required gravel from Homer by landing craft rather than to permit and mine the local source.A final determination will be made after the geotechnical investigation and as-built survey of the proposed tank farm site are completed.
