2.0 EXISTING FACILITIES -FUNCTION AND CAPACITY
There are six separate tank farm facilities located within Elim.These are the IRA
Native Store retail facility,City Pumphouse,City Shop,Elementary School,HighSchool,and AVEC.The net fuel storage capacity of each entity,based on 90%of the gross tank shell capacity,is provided in the following table.
EXISTING NET FUEL STORAGE CAPACITY
|Facility Gasoline*Heating Fuel*
Native Store 45,500 gallons 23,130 gallons
City N/A 88,500 gallons
BSSD School N/A 53,300 gallons
AVEC N/A 65,800 gallons
Total 45,500 gallons 230,730 gallons
*Net capacity is based on 90%of tank shell dimensions to account for actual
useable fuel in the tank.
Elim Native Store.The Native Store tank farm provides the only retail sales ofgasolineandheatingfuelwithinthecommunity.The tanks are located adjacenttothestore,along the edge of the beach on Norton Bay,and are not diked or
fenced.The tanks are hard-piped to a dispenser next to the tank farm.Fuel is
dispensed from a service station style dispenser into vehicles and portable
containers.The tanks are filled via a direct hose connection to the barge.
The facility consists of six vertical and one horizontal above ground welded steel
tanks for retail sales of gasoline and heating fuel.The six vertical tanks containgasoline,and the horizontal tank contains #1 heating fuel.The gross tank shell
capacity of the vertical tanks is 50,600 gallons.The gross tank capacity of thehorizontaltankis25,700 gallons.Five of the six vertical tanks are small BIAstyle(bolted roof)tanks that range in net capacity (based on 90%of shellcapacity)from 4,600 gallons to 6,700 gallons.The sixth vertical tank is a weldedrooftankandis14feetindiameterby18feettallwithanetcapacityofthe18,700 gallons.The net capacity of the horizontal tank,which is owned byYukonFuelCompanyandisonloantotheStore,is 23,100 gallons.
The horizontal tank appears to be suitable for reuse with installation of saddlesandminormodifications.The 14 foot diameter tank appears to be suitable for
reuse with modifications to the top and bottom.Both tanks require sandblasting
and painting.The small capacity BIA style tanks are in marginal condition andarenotappropriateforgasolinestoragebecausetheboltedroofscausehighevaporativelosses.Considerable renovation and repair would be required tomakethesetankssuitableforlong-term use.It would not be cost effective torenovatethesetanksduetothehighcostofrepair,installation of gauges,appurtenances,etc.on a per tank basis and the relatively small capacity of the
tanks.
City Pumphouse.This facility consists of four vertical welded steel tanks locatedadjacenttothepumphouseonthewestsideoftown.The tanks are used forstorageofheatingfuelforoperationofthepumphouseandheatingthecommunitywatercirculatingloops.Fuel is also stored for bulk transfer to othercommunityfacilitiesforheating,for heavy equipment operation,and for MosesPoint.The tanks are hard-piped to the pumphouse day tank.Fuel is transferredbygravityinbulkusingafuelratedhoseandnozzle.The tanks are filled via a

et foot long,3”Schedule 80 welded steel pipeline that was constructed in1994.
Two of the tanks are the same type and capacity as the large vertical tank at theNativeStoreandprovideacombinednetcapacityof37,400 gallons.The othertwotanksareBIAstyletankswithbolt-on roofs and provide a net capacity of6,700 gallons and 7,400 gallons each.One of the large tanks has a small fuelstainatthebaseofthetankattheshelltofloorseam,where there appears tohavebeenanattempttorepairadefectiveweld.
The large tanks appears to be suitable for reuse with modifications to the top andbottomandweldinspectionandrepair.The small capacity BIA style tanks alsoappeartobesuitableforreusewithminormodifications.All of the tanks requiresandblastingandpainting.
City Shop._This facility consists of 2 vertical welded steel tanks locatedadjacenttotheCityShoponthewestsideoftownnearthenorthendofthe
airport.The tanks are of the same configuration and capacity as the large NativeStoretankandprovideanetcapacityof37,400 gallons.These tanks were
reportedly brought into the community in the early 1990's by DOT to provide fuelstorageduringtheairportrenovationproject.The tanks were used subsequenttotheairportproject,but have been taken out of service reportedly due toleakingweldjoints.The tank tops are in poor condition and the bottoms of the
tanks appear to be in direct contact with the ground.The age of the tanks is not
known but based on the poor condition it is assumed that they are quite old.Thetanksappeartobebeyondtheirservicelifeandnotworthrenovating.
BSSD School.This school facility consists of eight vertical welded steel BIA
style tanks located in two separate tank farm areas with four tanks each.Thetanksareusedforstorageofheatingfuelforheatingtheentireschoolcomplex.
The tanks are hard-piped to the elementary and high school day tanks and
teachers'housing units.The tanks are filled via a 1,000 foot long,3”Schedule80weldedsteelpipelinethatwasconstructedin1994.The fill pipeline is also
used to fill the adjacent AVEC tank farm facility.
Heating fuel use is augmented by waste heat provided from the nearby AVECpowerplant.The tanks provide a total net capacity of 53,300 gallons.The eighttanksappeartobeinfairtogoodconditionandsuitableforreuse.
AVEC.This facility consists of eight vertical welded steel BIA style tanks locatedadjacenttotheAVECpowergenerationplantneartheschoolandCityoffice.The tanks are used for storage of diesel fuel for electrical generation.
The tanks are hard-piped to the power plant day tank.An electric solenoid valveisusedtoisolatethetankfarmmanifoldpipingfromthedistributionpipingtothepowerplant,and is actuated by the day tank pump.The tanks are filled via a1,000 foot long,3”Schedule 80 welded steel pipeline that was constructed in1994.The fill pipeline is also used to fill the adjacent BSSD tank farm facilities.
The tanks appear to be in fair condition and suitable for reuse.The total netcapacityofthefacilityis65,800 gallons.

3.1.Planned Infrastructure Improvements
It is important to evaluate the impact of planned near-term infrastructure
improvement projects on existing utility systems.The addition of new homes,
airport lighting,water and sewer extensions,and school additions all can havetremendousimpactsontheadequacyofexistingutilities.The followinginfrastructureprojectshavebeenidentifiedforthecommunityofElim.
There are reportedly 20 HUD homes planned to be built in Elim during thesummerof1998.Typical heating fuel consumption for a HUD home averages
about 1,000 gallons/year.Due to the readily available supply and common useofwoodforresidentialheat,it is estimated that the average heating fuel
consumption of the new HUD homes will be about 500 gallons/year.The impactofthenewhousingisexpectedtoresultinanincreaseinheatingfuelconsumptionofabout10,000 gallons/year.The new homes will also increasethefuelconsumptionoftheAVECpowerplanttomeettheincreasedelectric
load.
PHS is in the process of having a sanitation master plan developed to define thelongtermsanitationneedsofthecommunity.Due to the excess fuel capacitythattheCitycurrentlyhas,it is not anticipated that improvements to the waterandsewersysteminElimwillincreasetheheatingfuelneedsbeyondtheCity'scurrentcapacityinthenextfivetotenyears.
The airport was rebuilt during the early 1990's and the runway is lighted.Therearenoneartermplansforupgradingtheairportthatareexpectedtoincreasetheheavyequipmentfuelconsumptionorelectricconsumption.
The BSSD currently receives waste heat from the AVEC power plant.The wasteheatsystemreportedlyisnotfunctioningatpeakperformanceduetoapossibleleakinthearcticpiping.The result is that the arctic piping to the high school isairlockedandonlytheelementaryschoolreceiveswasteheat.The amount ofheatingfuelsavingsachievedbythewasteheatsystemisunknownbutestimatedatnomorethan10,000 gallons per year.The residents of Elim haveexpressedadesirefortheAVECpowerplanttoberelocatedoutsideofthecommunity.If the plant is moved far from the school,there will be no waste heatavailable,which would increase the school's annual heating fuel consumption.

3.2.Tank Capacity Requirements
Elim Native Store.The current Store tank capacity is less than its current
annual retail sales for gasoline and heating fuel.This requires at least two fueldeliveriesperyeartomeetthecommunity's retail fuel needs.The past twoyear's,the store ran short of gasoline and heating fuel,and completely ran out ofbothproductsthispastJune.With the construction of the new HUD homes,theStore's heating fuel capacity may be as much as 10,000 gallons less that that
required to meet the projected heating fuel demand starting in the 1998/99heatingseason.Additional tank capacity is required to meet the Store's existingandnear-term retail fuel needs.
City.The four tanks located at the City Pumphouse provide adequate storagecapacitytomeettheCity's long term heating fuel needs.The tanks located attheCityShoparenotneededforthisproject.
BSSD School.The eight vertical BIA tanks provide more than adequate storagecapacityfortheschool.Any increased fuel demand caused by future expansionoftheschoolcomplex,or loss of waste heat,can be readily accommodated by
the existing tank capacity.
AVEC.The eight vertical BIA tanks provide minimal storage capacity for theexistingpowerplantneeds.Additional tank capacity will be required to meet
AVEC's long term fuel needs.
The following table compares the annual fuel use by category to the proposednetuseabletankcapacityforthenewfacility:

The City dike contains the four existing Pumphouse tanks.Space is provided toreplacethetwosmallerBIAtankswithfuture14footdiameterverticaltanks.AtruckloadingareawillbeprovidedadjacenttotheStoredispensingtankandthe2”diameter Store heating fuel transfer pipeline will be used for bulk transfer tothetruck.A 2,000 gallon double wall "day”tank will be installed at the
pumphouse and will be filled by a tanker truck.
The BSSD dike contains seven of the eight existing elementary and high schoolBIAtanks.The eighth tank will be placed in a containment dike at the school
complex to serve as a "day”tank.Fuel will be transferred from the bulk tanks to
the day tank via a 2”diameter welded steel pipeline which will be shared with
AVEC.Due to the layout of the dike,space is provided for one future tank.
Since it does not appear that the school will require additional capacity,the sizeandcostoftheschooltankfarmcouldbereducedbyinstallingsixofthetanksinthedikeandtransferringonetanktoAVEC.
The AVEC dike contains seven of the eight existing BIA tanks.The eighth tankwillbeplacedinacontainmentdikeadjacenttothepowerplanttoserveasa"day”tank.Fuel will be transferred from the bulk tanks to the day tank via a 2”diameter welded steel pipeline which will be shared with BSSD.Space isincludedforthreefuture11'diameter BIA or equivalent tanks.
4.1.Site
The tank farm is located east of the Elim Airport property near the southern endoftheairport,approximately 2300 feet south of the City Office.This location was
selected by the residents in an effort to reduce the risk of fire and spills and thesmelloffuelwithinthecommunity.The dispenser and dispensing tank will belocatedapproximately200'west of the City office.A gravel access road will runeastofandparalleltotheElimairportfromthedispensingstationtothetankfarmalonga60widefootrightofway.The fuel pipelines and power line alsoareroutedwithinthe60footrightofway.
The tank farm site,dispensing area,and road right of way are all located withinU.S.Survey 2548,a 297,982 acre tract of land belonging to the Elim NativeCorporation.A Certificate to Plat was prepared by Land Title Company ofAlaska,Inc.,on September 25,1997.The certificate confirmed that the subjectpropertyisownedbytheElimNativeCorporationwithoutrestrictionsexceptfortraileasementsandrecreationalsiteswhichdonotappeartoconflictwiththisproject.A copy of the Certificate is included in Appendix C.The City is requiredtohavesitecontrolasaconditionofitsCDBGgrantpriortostartingconstruction.A long term lease or title to the property must be conveyed to the City.
The entire site is over 100'above sea level,well above any threat of flooding;therefore,no additional site elevation or protective structures are required to
meet flood mitigation requirements.
The site slopes easterly toward Norton Bay at an average grade ofapproximately10%over the length of the site.The natural vegetation consistsprimarilyofsmallsprucetrees.The road right of way and entire tank farm sitewererecentlyclearedbytheCityofElim.Small brush,grass,and a thin layerofmossyorganicmatstillremain.Four test pits were dug at the site for a prior

engineering study.The test pits were open at the time of the field investigationandrevealedalayerofsiltysoilsapproximately3'deep over broken angulargravel.Bedrock was reportedly hit at a depth of less than 5'in one of the pits.No evidence of permafrost or other questionable soils was observed.The sitewillbestrippedofvegetationandorganics.Silty soils on the uphill end of thedikewillbecutandusedasfillonthelowerendtopartiallylevelthesite.Aminimumof3'of structural fill will be placed over the entire dike area.All fill will
be placed in 8”maximum lifts and compacted to 90%minimum density.
A previous engineering design showed the four dike cells arranged in anapproximatelysquareshapewithtwotiersoftwodikecellseachrunningdownthehill.Potential problems were anticipated with this arrangement due to the
steep slope of the site.Using a 2.5:1 dike side slope on the 10:1 grade,thedownhilldikewallofthefirsttierwillbeapproximately10'high (25'horizontal.)This could create problems with storm water runoff into the lower tier.Also,anysettlementoftheupperdikecouldpotentiallydisturbtherelativelylowwallonthe
uphill side of the lower dikes.Based on the above,it was determined that a longnarrowsingletierofdikeswouldbebettersuitedtothissite.
4.2.Secondary Containment
The Uniform Fire Code and E.P.A.regulations require fuel tanks to be installed
within a secondary containment structure that is capable of holding the contentsofthelargesttankplussufficientfreeboard(usually 6”to 12")to hold
accumulated precipitation.Based upon the availability of local earth movingequipmentandlocalgravel,a gravel berm with a membrane liner wasdeterminedtobethemostcosteffectivemeansofprovidingsecondary
containment.
The tank farm consists of four adjacent dike cells (one for each owner)with
individual membrane liners.Each dike cell is sized to contain the entire contents
of the largest tank within it plus a minimum of 10”of freeboard for precipitation.The AVEC and BSSD dikes are separated by a full height dike wall.Anintermediatedikewall18”high separates the City dike from the Store dike.The18”high wall is used between the City and Store dike cells to reduce the footprintrequiredfortheCitydike,and still meet requirements for secondary containment.
A lined gravel berm will be constructed at the dispensing tank.In order to meetcurrentEPArequirementsforsecondarycontainmentattruckracks,the truckloadingareawillbeslopedtodrainintothedikeandthelinerwillextendfullyacrossthearea.A layer of geotextile fabric and an 8”deep cellular confinementgridwillbeinstalledoverthe6”gravel cover in the truck loading area to protectthelinerfromtrafficloads.

4”deep cellular confinement grid will be installed over the liner on the interior
dike walls to hold the gravel cover in place on the side slopes.
4.3.Tanks
At a minimum,the existing Store and City tanks will require interior cleaning,vapor freeing,and internal and external inspection.Should any significantcorrosionbeencountered,repairs will be made.It is assumed that the vertical
store tank will require a new bottom and the 14'diameter City tanks will requiresomeweldrepair.The horizontal Store tank will require a saddle and skidfoundation.New valve connections,water draw valves,normal vents,
emergency vents,and level gauges will be installed.All existing tanks will besandblastedandpainted.
All new tanks will either be shop built and labeled in accordance with UL 142,or
field erected in accordance with API 650 standards.All new tanks will also be
equipped with level gauges and other appurtenances as indicated for the
existing tanks.
Vertical tanks will be equipped with 8”wide flange steel beam foundations to
elevate the tanks above the bottom of the dike.The beams will be welded to the
tanks and placed on 4x12 treated timber mudsills at grade.The timbers will be
sized to limit soil bearing pressure to approximately 2,000 pounds per squareoot.
4.4 Piping/Valves/Accessories
All 3”and 4”piping will be schedule 40 black steel and all 2”diameter and
smaller piping will be schedule 80 black steel.Piping will be installed above
grade on treated timber sleepers and secured with steel pipe straps.All pipingjointswillbeweldedorflangedexceptforconnectionstopumpswhichmaybethreaded.Sufficient flanged joints will be provided to allow service of pumps andotherdevices.All connections to pumps and tanks will be made with stainless
steel flexible connectors.Each isolated section of piping will be provided with
pressure relieving devices to account for thermal expansion of product causedbytemperaturefluctuations.Provisions for movement of the piping caused bythermalexpansionandcontractionwillalsobeincluded.All valves will be steelbodyindustrialgradevalvesintendedforusewithfuels.
A single 4”diameter fill pipeline will be routed from the existing AVEC/BSSDmarineheaderapproximately3,000 feet to the tank farm.The pipeline will beroutedaroundtheschoolproperty,and along the tank farm access road paralleltotheairport.The 4”welded steel pipeline will be used for both heating fuel andgasoline,and will have a volume of approximately 2,000 gallons.The pipelinewillbestrippedusingapigbetweenandaftereachproductdeliverysothelinewillonlycontainfuelwhilethetanksarebeingpumpedbythebarge.A drip pan willbeprovidedattheterminationofthefillpipeline(marine header.)Separate 3”manifold piping will be provided for each dike cell to isolate ownership of fuel.Each tank manifold will be equipped with pressure relief and a 3”fill connectionwithintheStoredikeadjacenttotheterminusofthe4”fill pipeline.
A pair of 2”diameter transfer pipelines will be routed adjacent to the 4”fillpipelineapproximately2,300 feet from the tank farm to the dispensing tank.

5.0 PERMITTING
The Corps of Engineers has determined that a wetlands permit is not required.
The Division of Governmental Coordination has determined that no State review
for consistency with the Alaska Coastal Management Program is required.
The U.S.Fish and Wildlife Service has expressed its concern regarding thepresenceofeidersinthevicinityoftheproject(about 20 miles offshore).ThestatusofanyUSF&W permit requirements,pursuant to Section 7 of theEndangeredSpeciesActof1973,is undetermined at this time.Additional
information was recently provided to USF&W in response to request forinformation.A determination is pending.
6.0 SPILL RESPONSE
Because the new facility has oil storage tanks in excess of 660 gallons andreceivesdeliverybymarinevessel,it is subject to U.S.Environmental ProtectionAgencyandU.S.Coast Guard regulations.An Operations Manual and a LetterofIntentwillneedtobepreparedandsubmittedtotheCoastGuard.An Oil SpillResponsePlanwillneedtobepreparedandsubmittedtoboththeCoastGuardandtheEPA.The facility will also require preparation of Spill Prevention ControlandCountermeasures(SPCC)plan.Since each individual dike cell and the
tanks within it will be owned and operated independently by separate entities,the consolidated facility will technically be comprised of four individual tank
farms.Each owner will be responsible to prepare their own Operations Manual,
Response Plan,and SPCC Plan and operate their facility in accordance with it.
Spill response gear,including sorbent material,protective safety gear,and
possibly containment boom will be required.The owners can purchase equal
shares of spill response material and pool their resources through a cooperative
agreement.The project will not use all of the existing tanks;therefore,severalcontingencytankswillbeavailable.These tanks may be placed outside of thedikeforuseintheeventofamajorspill.
7.0 SCHEDULE
The duration of Phase |construction is estimated at 90 days total -30 days for
access road and pad/dike construction and 60 days for the remainder of thefacility.If Phase Il were to be built in the same season,a larger crew would berequiredandthedurationofconstructionwouldincreaseby10to20days.Construction of the access road and tank farm pad should begin in early June so
that the site is prepared by the time the first barge arrives in Elim,which should beinearlyJuly.Relocation of tanks and installation of piping,pumps,appurtenances,electrical,fencing,etc.will not commence until after barge arrival.
To meet this schedule,the final design should completed and submitted to the FireMarshallbyMarch.Procurement is required to begin in March to ensure deliveryofmaterialstotheSeattledockintimeforthefirstbargesailingtoNomewhichiscurrentlyestimatedatMay1.Shop fabricated tanks may need to be ordered asearlyasFebruarytoobtaincompetitivepricing.

8.0 COST ESTIMATE
Construction cost estimates have been developed based on a "modified"force-
account approach utilizing a combination of local labor and certified craftsmenunderthedirectionofanexperiencedsuperintendent.The estimated
construction costs do not include rental of local heavy equipment which hasbeenprovidedasanin-kind contribution.Costs were apportioned betweenownersbasedontheactualquantitiesrequiredforeachindividualfacilityandproratedcostofshareditemsandservices.Detailed construction cost estimates
for each Phase are included in Appendix A.The individual Phase costs are asollows:
Phase |Site Development $185,127
Phase |Native Store Tanks $525,379
Phase |Sub-Total $710,506
Phase Il City Tanks $152,249
Phase III BSSD Tanks $227,560
Phase IV AVEC Tanks $240,228
Project Total $1,330,543
The total project cost of $1,330,543 equals $4.47 per gallon based on a grosscapacityof297,500 gallons.
9.0 ALTERNATE SITE
Because of concerns that the remote site selected by the community may cause
the project cost to exceed available funding,the Division of Energy requestedevaluationofanalternatesiteasanoption.The main reasons given by thecommunityforlocatingthetankfarmsofarfromtownwereconcernsregardingthreatoffire,contamination from spills,and objectionable fumes.The following
responses are provided to these concerns:
e The Uniform Fire Code requires no more than 75'clearance from any of thetanksinthisfacilitytoapropertylinethatcanbebuiltupon.A moreconservativeguidelinewouldbeHUD's requirement for 300'separation from

e A properly designed and constructed tank farm with tank level gauges,welded piping,high quality valves,and overfill protection devices isconsiderablylesslikelytohaveaspill.In addition,liquid tight secondarycontainmentisprovidedtocatchvirtuallyallspills.The probability of asignificantspillfromthertanksthreateningthecommunityisverylow.
e The old BIA style tanks with bolted roofs have very high evaporative lossesandarethemainsourceoffumegeneration.The new tanks will have weldedroofsandbeequippedwithself-closing pressure-vacuum vents which willdrasticallyreduceemissions.The other source of objectionable fumes isevaporationfromcontaminatedsoils.As mentioned in the previousparagraph,the probability of spills occurring in the new facility is very low andthereforeunlikelytocauseanyfumes.

Concept Design Alaska Eneray and Engineering
Based upon observation of aerial photographs and the field investigation,it wasdeterminedthatthereisadequatespacesouthoftheproposeddispenserlocationtositetheentirefacility.To further alleviate concerns over fire hazards,the tank farm could be shifted south to provide a minimum 300'separation fromtheclosestbuildingwhichistheCityoffice.This site offers the followingadvantagesoverthecurrentselection:
e The cost of Phase |construction would be reduced by a minimum of$168,000 to a total of $542,506,which is within available current funding.The cost savings for the entire project would be well over $200,000.
e The length of the transfer pipelines will double the time required to fill daytanksanddispensingtanks.The long pipelines present a significant liabilityexposureandwillcontainover1,100 gallons of fuel which will be outside of
secondary containment structures at all times.Also,monitoring transfer
operations over such great distances is difficult and the likelihood of anoperatorleavingvalvesopenisgreatlyincreased.
e The length of the fill pipeline and the higher elevation of the proposed site willincreasethetimerequiredtofillthetanksbyapproximately50%over thealternatesite.This increases the risk of a marine spill and may eventuallyresultinadditionalfueldeliverycharges.Also,the volume of product that will
need to be pigged between each delivery will be approximately 2,000 gallons.
e The potential for theft and vandalism is far greater at a remote unattendedsite.Placing the tank farm within site of the dispenser would make frequentobservationthroughoutthedaypossible.
While the remote site may have some advantages,it appears that overall itincreasespotentialenvironmentalrisks.Development of an alternate site closertotownappearstowarrantfurtherconsideration,particularly if sufficient fundingisnotavailabletocompletetheprojectaspresentlyproposed.
