Due to site limitations,regulatory issues,and potential funding limitations,it wasdeterminedthattheAVECfuelstorageshouldbedevelopedseparatefromthe rest of the community fuel storage.The new consolidated facility will combine allofthefuelusedforpublicbuildingheatingandretailsalesintoacommondikejustwestoftheAVECfacilityandwillshareacommonfillpipeline.Both newtankfarmswillbeequippedwithnecessarytransferpipelines,pumps,dispensers,and appurtenances and will comply with current State and Federal codes and regulations. A site investigation was performed by Brian Gray and Trevor Krupa of AEE fromSeptember1throughSeptember2,1998.Existing tanks were examined todeterminesuitabilityforreuse.Two proposed sites were examined for the newconsolidatedtankfarmandthroughdiscussionswithGlenSkin,Noorvik CityAdministrator,the site adjacent to the AVEC power plant was determined to bepreferable.A preliminary topographic survey was performed at the selected siteandlocationsfordaytanksandroutesforpipelineswereexplored. Additional information was obtained from the following individuals: e Glen Skin,City of Noorvik 636-2100 e Robert Wells,Native Village of Noorvik 636-2144 e Linda Sampson,Noorvik Native Store 636-2212 e Pauline Morris,Morris Trading Post 636-2161 e Lonny Tebbits,NWAB School District 636-2178 e Jim Shepherd,NWAB School District 442-3472 e Dan Hodges,Crowley Marine Services 442-3211 e Jim Dwight,Crowley Marine Services (800)248-8632eSeanHochanadel,Crowley Marine Services 257-2835 e Matt Dixon,U.S.Public Health Service (PHS)729-3535 e Blaine Gallaher,Alaska Department of Transportation 636-2186 e Bish Gallahorn,KIC Construction 636-2193 Prior to the field investigation,available information was obtained and analyzed,including aerial photographs,community profile,survey plats,engineeringstudies,Corps of Engineers Wetlands and flood information,erosion studies,and other relevant data. During the field investigation it was determined that site soil conditions warrant ageotechnicalinvestigation.Duane Miller and Associates is scheduled to performasub-surface soils investigation in December after the site is sufficiently frozentoallowaccesswithadrillrig.The concept design has been based on soils dataobtainedfrompriorprojectsatotherlocationswithinNoorvik.Results of the site-specific geotechnical investigation will be incorporated into the final design. Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering 2.0 EXISTING FACILITIES -FUNCTION AND CAPACITY The existing fuel storage facilities are scattered throughout Noorvik,typicallylocatedatornearthepointofconsumption.The net fuel storage capacity,based on 90%of the gross tank shell capacity,is provided for the variousproductsusedforeachentityinthefollowingtable: EXISTING NET*FUEL STORAGE CAPACITY[Facility Unieaded Gas Heating Fuel Diesel Fuel AVEC 131,100 gallons NWAB School District 85,500 gallons City of Noorvik 27,900 gallons Morris Trading Post 21,400 gallons 31,700 gallons Noorvik Native Store 58,000 gallons 57,500 gallons "Total 79,400 gallons 202,600 gallons 131,100 gallons "Net capacity is based on 90%of tank shell dimensions to account for actual useable fuel in the tank." While it is evident that a sincere effort has been made to maintain and even upgrade many of the tank farms,all were found to be out of compliance with regulations.None of the facilities appear to have been built according to codeoriginally.Current deficiencies observed include: e Improper Secondary Containment (Diking)-None of the tanks are within a proper liquid tight secondary containment system as required by the FireCodeandEPAregulationsandmostofthetankshavenocontainment. e Improper Site Location -Three of the tank farms are located within the flood plain of the Kobuk River. e No Security Fence -Five of the tank farms are located in the communityproperandinareasofhighvehicleandpedestriantrafficwithoutanysecurityfencing.This presents an extreme hazard to the community with childrencommonlywalkingandplayingaroundthetanks.It also greatly increases thechanceofaspillorfireduetovandalismandtheftwhenunattended. e Improper Tank Foundations -Most of the tanks are installed on timber cribbing foundations in violation of the Fire Code.The foundations are installed directly on unstable permafrost and the tanks are beginning to lean. e Improper Piping and Valves -Existing piping systems are steel pipe with acombinationofthreadedandgroovedendjoints.These joints have a tendency to leak and fail over time.In addition,some tanks are connected tothepipingwithrubberhose.Many of the valves are made of bronze,inviolationoftheFireCode,and appear to be worn out. ¢Wiring Not in Compliance With the National Electrical Code -The wiring for the dispensers and lights does not meet code and presents a serious explosion/fire hazard to employees and customers. Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering e Dispensing From Above-Ground Tanks Without Protective Systems -State Fire Marshall requirements stipulate protective devices and piping systems tolimitthequantityoffueldirectlyconnectedtothedispensersandtopreventagravitydischargeoffuelintheeventofafailureofthedispenserorpiping.No protective devices are installed and the current piping configurationprovidesforover60,000 gallons of product directly connected to dispensers. The combination of deficiencies poses a significant threat to public safety andtheenvironment.In addition,the community may be denied delivery of fuel inthenearfuturebytheCoastGuardorfuelcarriersifthefacilitiesarenotrenovatedwhichwouldcreateasignificanthardshipforlocalresidents.A majorupgradeisrequiredtobringeachoftheexistingfacilitiesintocompliancewithcurrentcodesandregulationsandtomeetthelong-term fuel storage anddispensingneedsofNoorik.Consolidating the individual retail and publicbuildingheatingtankfarmsintoonefacilityisthemostcost-effective solutionbecauseitwillreducenotonlyconstructioncostsbutalsolong-term operation and maintenance expenses.

evaluate the impact of planned near-term infrastructureimprovementprojectsonexistingutilitysystems.The addition of new homes,airport lighting,water and sewer extensions,and school additions all canadverselyimpacttheadequacyofexistingutilities.The following infrastructureprojectshavebeenidentifiedforthecommunityofNoorvik. A total of 18 new HUD homes were completed in Noorvik in the spring of 1997, after the main heating season.Local residents tend to heat their homes with acombinationofwoodandheatingfuel.It is estimated that the new homes willincreaselocalheatingfuelconsumptionbyapproximately12,000 gallons for the1998-99 heating season.Noorvik is reported to be growing and is currently intheplanningstagesforfutureHUDhousingprojectsthatwillfurtherincreasethedemandforfueloil.The new homes will also increase the electrical generationloadandassociatedfuelstoragerequirements. The community is in the process of upgrading its water and sewer system.Newwaterandsewermainswererecentlycompletedandareexpectedtoincrease the City's heating fuel demand by 7,500 gallons to a total of 30,000 gallons forthe1998-99 heating season.Additional expansion of the water and sewersystemisplannedthatcouldincreasethefueloilconsumptionbyanadditional5,000 gallons in the near future.Electrical loads will also increase due toadditionalpumpingandheattracesystems. A new runway is currently under construction in Noorvik.The impact to thecommunityheating/diesel fuel consumption from this project is expected to be negligible. The existing High School building was constructed circa 1970's.Mr.JimShepherdwiththeNWABSchoolDistrictindicatedthatfundinghasbeenrequestedtoexpandtheschoolbuildingto278%of its current size and relocatetheElementarySchooltothenewfacility.The fuel use increase has beenestimatedtobeproportionaltotheareaincrease.The old Elementary School isexpectedtoberenovatedtoserveasteacherhousingsothefuelconsumptionforthisfacilitywilllikelyremainatornearitscurrentlevel.The school addition isanticipatedtohaveasignificantimpactontheelectricalgenerationloadandadditionalfuelstoragewilllikelyberequiredatAVECtoaccommodatethis. 3.2 Tank Capacity Requirements Since there are numerous entities requiring varying quantities of fuel it is necessary to size the tank farm to meet the combined needs of each user withsufficientcapacitytoaccommodatefuturegrowth.The table on the followingpagecomparesthecombinedannualuseofeachproductandentitytotheproposednetuseabletankcapacityforthenewfacility: Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering PROPOSED NET TANK CAPACITY VERSUS CONSUMPTION |Facility Annual Use*Net Capacity** AVEC 138,000 gallons 155,000 gallons "Diesel Fuel Sub-Total 138,000 gallons 155,000 gallons NWAB School District Heating Fuel 82,000 gallons 90,600 gallons City of Noorvik Heating Fuel 35,000 gallons 40,500 gallons Morris Trading Post Heating Fuel 32,000 gallons 52,800 gallons Noorvik Native Store Heating Fuel 65,000 galions 70,300 gallons Heating Fuel Sub-Total 214,000 gallons 254,200 gallons Morris Trading Post Gasoline 20,000 gallons Noorvik Native Store Gasoline 55,000 gallons 91,600 gallons Gasoline Sub-Total 75,000 gallons 91,600 gallons *Current or estimated near-term use based on planned development.

The south subdivision of the dike contains the six existing High School tanks and four new 20,300 gallon heating fuel bulk storage tanks,two for the High SchoolandtwofortheCity.The center subdivision of the dike contains the three existing Morris heating fuel tanks,two existing 23,700 gailon Native Store heating fuel tanks,and one new 23,700 gallon Native Store heating fuel tank.The north subdivision of the dike contains four new 23,700 gallon Native Store gasoline tanks and a new 14,000 gallon dual product dispensing tank. To comply with State Fire Marshall requirements for dispensing from above ground tanks,the piping must be configured to limit the capacity of tanks directlyconnectedtodispensersto10,000 gallons each.Transfer pumps,overfill protection devices,and controls are required to provide appropriate interconnection between the bulk tanks and the dispensing tanks.One of the 6 Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering existing Morris tanks is only 10,000 gallons capacity and can readily beconfiguredtoserveasadispensingtank.A new dual product dispensing tank isrequiredfortheNativeStore.Under the proposed scenario,the Morris tankswouldbeusedexclusivelyforheatingfueldispensingandtheNativeStoretankswouldbeusedforbothgasolineandheatingfuel.A dual product dispenser forNativeStoregasolineandheatingfuelandasingleproductdispenserforMorrisheatingfuelwillbelocatedinasecurityenclosurejustnorthofthedike. Because the cost of the pad/dike construction is relatively high and new bulkstoragetanksarerequired,it was determined to be more cost effective to build the tank farm now to meet future growth requirements rather than provide spaceinthedikeforfuturetanks.The proposed configuration provides adequate storage capacity to meet all of the Community's near-term projected annualneedswithapproximately20%reserve for increased demand. 4.1 Site The community had originally selected a site adjacent to the AVEC power plantfortheconsolidatedtankfarm.A prior engineering study examined this site and two other possible sites.A site south of the High School was selected in theprioreffortbecauseofbetterdrainageandsurfacesoilconditions.This site wasre-examined and determined to have some drawbacks.It is too close to new residential development,has poor access for pipelines and vehicle traffic,and isessentiallyblockedoffbynewabovegradesewerforcemainsmakingconstructionverydifficult.The original site adjacent to AVEC was determined tobethebestlocationforaccessandrequirestheleastpipingtoreceivebargedeliveriesandtoserveallthenecessaryfacilities.There do not appear to be any soils or drainage problems that cannot be overcome through proper designandconstruction.The existing GCI telecommunications satellite dish andmodulewillneedtoberelocatedbutcanremainonthesameproperty. The consolidated tank farm is located entirely on Lot 20,Block 26,U.S.Survey5069,approximately 100'west of the AVEC power plant.The property is presently undeveloped with the exception of a telecommunications satellite dish.The land is listed as belonging to the City of Noorvik.A Certificate to Plat waspreparedbyLandTitleCompanyofAlaska,Inc.,on September 29,1998.The certificate confirmed that the subject property is owned by George E.M.Gustafson,trustee for the Townsite of Noorvik.No lease or other agreement for the GCI facility was found.Further research will be required to ensure proper site control is obtained.A copy of the Certificate is included in Appendix C. The entire site is above the 100 year flood plain and no additional site development features will be required to meet flood mitigation requirements.An erosion study for the old airport was reviewed to ascertain the threat to the newtankfarmsite.The old main runway 2-20 was recently abandoned due to extreme erosion.Erosion rates as high as 16'per year were encountered in an area approximately 1/2 mile southwest of the tank farm site.A review of aerialphotographsfrom1962through1995donotshowanysignificanterosionintheareawherethenewtankfarmwillbeconstructed.In addition,the site is located over 1,000'inland so even if the maximum recorded rate of erosion of 16'per year were to occur in the vicinity of the tank farm it would take over 50 years tothreatenthefacility.Based on this,it was determined that erosion of the KobukRiverdoesnotconstituteasignificantthreattothenewtankfarm. Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering The site is basically level with slight drainage northwesterly towards the KobukRiver.The natural vegetation consists primarily of tundra and extremely sparselowbrush.Based on soils explorations conducted elsewhere in the community,site soils are expected to consist of permanently frozen silt with occasional zonesofpeatandmassiveicecoveredbyonetothreefeetofmossyorganicmatandorganicsilt.The soils are expected to be extremely unstable if thawed,thereforeitisessentialthatthenewtankfarmmaintainstheexistinggroundinafrozenstate.Existing mossy vegetation and organics will be left in place and coveredwithawovengeotextilefabricpriortoplacingfill.Fill will be placed early in thesummerafterthesurfacesnowmeltsandthesurfacewaterdrainsoff.A minimum of 3°of fill will be placed over the tundra and covered with 4"of rigidinsulation.Thermal siphons will be installed in the fill below the insulation to maintain the frozen state of the sub-grade.A leveling course of fill will be placedovertheinsulation.The actual configuration of the pad may be revised in thefinaldesignbasedonresultsofthesub-surface geotechnical investigation.All fillwillbeplacedin8”maximum lifts and compacted to 90%minimum density.Theentirepadwillbeallowedtosettleforaminimumofsixweekspriortofinalgradingandinstallationofthelinerandtanks. Three local fill sources were considered.A haul road to a new gravel source is currently being built as part of the airport relocation project.This material is notexpectedtobeavailableuntillatein1999orpossibly2000basedonthecurrentconstructionschedule.The most readily available fill material is silty sand alongthebeachoftheKobukRiver.This material is frost susceptible and wiil likelyhaveahighmoisturecontentinthespring.The best potential source of fill is theoldabandonedrunway2-20.The contractor for the airport project has first rightstothismaterialbuthasnotmadeanydefiniteplanstoutilizeit.If this material is not used for the new airport,it is likely that it could be made available for the tankfarm.A total of 5,000 cubic yards of unclassified fill is estimated to be required.An additional 500 cubic yards of select material is required for surface cover inthedikeandtrafficareas.This should be a clean gravel to provide a durablesurface.This material may be able to be extracted from the surface layer of theabandonedrunway,hauled from the new gravel pit,or even hauled in by barge. 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 fill material,an earthen berm with a membrane liner on top of an earthen pad was determined to be the most practical means of providing secondary containment.The bulk tank dike is sized to contain the entire contents of the largest tank within it (25,000 gallons)plus 12”of freeboard for precipitation.The dike is subdivided into threecompartmentswith18"high intermediate curbs.The entire dike will be lined withamembranelinercompatiblewithboth#1 heating fuel and gasoline.A non- woven geotextile fabric will be installed above and below the liner to preventpunctureanddamageanda4”deep layer of gravel cover will be placed over theliner.A 4”deep cellular confinement grid will be installed over the liner on theinteriordikewallsandtheintermediatedikestoholdthegravelcoverinplaceon the side slopes. The "day”tanks at the High School and City will be double wall construction.They will not be installed within dikes but will be equipped with redundant overfill 8 Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering protection devices as required by the EPA to meet the intent of secondarycontainmentrequirements.Earthen pads will be constructed to provide a stablebaseforthetanks. 4.3.Tanks A total of 36 existing tanks will be cleaned,purged,and taken out of service aspartofthisproject.A few of the tanks will be retained to serve as spillcontingencystorage.The rest will be demolished and disposed of.A total of 12existingtankswillberefurbishedandusedinthenewfacilityand11newtankswillbeinstalled.The existing vertical tanks at the High School will be renovated to serve as heating fuel storage.The two largest Morris Trading Post tanks andthetwolargeNativeStorehorizontaltankswillberenovatedtoserveasheatingfuelbulkstoragetanks.The 10,000 gallon Morris tank will be renovated to serveasaheatingfueldispensingtank.All other existing single-wall tanks will becleaned,vapor freed,and demolished or retained for contingency storage asappropriate.The existing 7,900 gallon double wall City tank will be renovated toserveastheHighSchool"day"tank.All existing tanks being reused will requireinteriorcleaning,vapor freeing,and internal and external inspection.Should anysignificantcorrosionbeencountered,repairs will be made.New manholes,valve connections,water draw valves,normal vents,emergency vents,and levelgaugeswillbeinstalled.Several of the tanks will require modification of the saddles and the two Native Store tanks and one of the Morris tanks will requireinstallationofnewskids.All existing tanks will be sandblasted and painted. The new bulk storage tanks will be shop built single wall horizontal welded steel tanks built and labeled in accordance with UL 142 and equipped will steel saddleandskidfoundations.The new City "day”tank will be similar to the new bulktanksexceptfordoublewallconstruction.All new tanks will also be equippedwithlevelgaugesandotherappurtenancesasindicatedfortheexistingtanks.Double wail tanks will also be equipped with float-type mechanical fill limiters andhighlimitalarms/cut outs.The tank skids will be placed on 4x12 treated timber mudsills at grade.The timbers will be sized to limit soil bearing pressure to1,500 pounds per square foot. 4.4 Piping/Valves/Pumps/Accessories All 3”above-grade piping will be schedule 40 black steel and all 2”diameter and smaller above-grade piping will be schedule 80 black steel.All below-gradepipingwillbeschedule80steelwithahighdensitypolyethylenecoatingand cathodic protection.Above-grade piping will be installed on treated timbersleepersandsecuredwithsteel!pipe straps.All piping joints will be welded or flanged except for connections to pumps which may be threaded.Sufficientflangedjointswillbeprovidedtoallowserviceofpumpsandotherdevices.Allconnectionstopumpsandtankswillbemadewithstainlesssteelflexible connectors.Each isolated section of piping will be provided with pressure relieving devices to account for thermal expansion of product caused bytemperaturefluctuations.Provisions for movement of the piping caused by thermal expansion and contraction will also be included.All valves will be steelbodyindustrialgradevalvesintendedforusewithfuels.

The dispensers will be installed within a post structure with a concrete floor slab,metal roof,and full-height chain link fence walls.All valves will be provided with 10 "yy Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering lockable handles to prevent theft and vandalism.Pump controls will be installedwithinfencedsecurityareas.Area lighting controlled by photocell will beprovidedatthedispensers,pump controls,and dike for security and spilldetectionandtoenhancewinteroperation. 5.0 AVEC FACILITY DESCRIPTION The AVEC tank farm will provide storage for all of the diesel fuel required forlocalelectricalgeneration.The design provides a single dike to contain all of thebulkstoragetankswithoneintermediatewalltolimitindividualdikedareaCapacityto3,750 barrels or less in accordance with Uniform Fire CodeRequirements.Because the electrical generation load and associated fuel storage requirements are expected to increase significantly with the schooladdition,the proposed facility includes additional tank capacity.Space has alsobeenprovidedinthedikeforadditionalfuturetanksshouldelectricloads continue to increase. §.1 Site The tundra soils at the existing AVEC tank farm site have been severelydamagedwhichhasresultedinthawingofthesub-grade permafrost.Extensiveremedialeffortswouldberequiredtore-freeze and stabilize this site and the tanks would have to be temporarily relocated while this took place.It wasdeterminedthatamorecost-effective solution would be to construct a new padanddikeonundisturbedgroundneartheAVECpowerplant.The best location appears to be the land immediately southeast of the existing power plant.Thislandiscurrentlyairportpropertybutservedastheclearzoneforrunway2-20whichisnowabandoned.Further research is required to ensure that clear title can be obtained for this property but there does not appear to be any reasonwhyitshouldnotbepossible. The entire site is above the 100 year flood plain and no additional sitedevelopmentfeatureswillberequiredtomeetfloodmitigationrequirements.The proposed site is approximately 200'closer to the Kobuk River than the proposed consolidated tank farm;therefore,erosion is not a significant threat.The site is basically level with slight drainage to the north.The natural vegetation consists primarily of tundra and extremely sparse low brush.Site soils are expected to be similar to the consolidated site and a similar pad anddikeconfigurationisanticipated.A sub-surface geotechnical investigation will beperformedonthissiteandthefinalpadanddikeconfigurationwillbebasedupontheresults.A total of 2,000 cubic yards of unclassified fill and 200 cubic yards of select gravel cover is estimated to be required.Material will come fromthesamesourcesastheconsolidatedtankfarm. 5.2.Secondary Containment Based upon the availability of local fill material,an earthen berm with amembranelinerontopofanearthenpadwasdeterminedtobethemost practical means of providing secondary containment.The dike is sized tocontaintheentirecontentsofthelargesttankwithinit(9,600 gallons)plus 12”offreeboardforprecipitation.The dike is subdivided into two compartments withan18"high intermediate curb.The entire dike will be lined with a membranelinercompatiblewith#1 diesel fuel.A non-woven geotextile fabric will be installed above and below the liner to prevent puncture and damage and a 4” 11 Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering deep layer of gravel cover will be placed over the liner.A 4”deep cellularconfinementgridwillbeinstalledoverthelinerontheinteriordikewallsandtheintermediatedikestoholdthegravelcoverinplaceonthesideslopes. 5.3.Tanks Historically,most AVEC tank farm renovations have utilized the existing tankswithminimalmodification.The existing tanks in Noorvik do appear to be suitableforre-use but significant modifications will be required.The design shown ondrawingM5andthecostestimatelistedasOption#1 are based on refurbishingtheexistingtanks.Under this scenario,all existing tanks will require interiorcleaning,vapor freeing,and internal and external inspection.Should anysignificantcorrosionbeencountered,repairs will be made.New flanged valveconnections,water draw valves,normal vents,emergency vents,and level gauges will be installed.All existing tanks will be sandblasted and painted.To meet increased capacity requirements,three new vertical tanks similar to therenovatedexistingtankswillbeaddedtothefacility.The new bulk storage tankswillbeshopbuiltsinglewallverticalweldedsteeltanksbuiltandlabeledin accordance with UL 142. Because of the relatively high cost per gallon of modifying the existing smalltanks,a second option was explored which is listed in the cost estimate as Option #2.Under this scenario eight new horizontal 20,300 gallon tanks,identical to the proposed new tanks for the School and City,would be installedandtheexistingtankswouldbedemolishedanddisposedof.The larger volumetanksrequirelessspace;therefore,the dike and pad area is reduced byapproximately30%.In addition,requirements for piping,valves,andappurtenancesaresignificantlyreduced.Because of the cost reduction factorsassociatedwiththisoption,the cost of Option #2 is estimated at only 2%morethanthecostofOption#1.This option also has other significant advantages: e lf defects are encountered in the existing tanks that require significant fieldrepair,the project cost will exceed that of new tanks. e Many of the existing tanks are over 20 years old and,even after renovation, will have a limited remaining life. e The old tanks have bolt-on roofs which contribute to higher evaporativelossesandwaterintrusion. e Twenty tanks versus eight tanks increases the labor required to monitor andoperatethefacilityandgreatlyincreasesthechanceofleaksandspills. Replacing the old existing tanks with new tanks appears to be the best solution. 5.4 Piping/Valves/Pumps/Accessories All piping,valves,and fittings will be the same as listed for the consolidatedfacility.The 3”diameter heating fuel fill pipeline that serves the consolidatedtankfarmwillbeextendedtotheAVECfacility.A lockable ball valve and check valve will be provided at every branch on the shared fill pipeline to ensureinventorycontrolandsecurity.An above grade 2”diameter transfer pipeline willberoutedfromthebulkstoragetankstotheexistingdaytankinthepowerplant.Existing transfer pumps and controls will remain in service.A new 2"normallyclosedsolenoidvalvewillbeinstalledinthedikeandinterlockedwiththepumps. 12 Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering 5.5 Security The entire bulk storage dike will be enclosed by a 6'tall chain link fence with abarbedwiretop.Two access gates will be provided into the fenced enclosure.All valves will be provided with lockable handles to prevent theft and vandalism.Area lighting controlled by photocell will be provided at the dike for security andspilldetectionandtoenhancewinteroperation. 6.0 PERMITTING A Coastal Zone Management Project Questionnaire will be completed andsubmittedtotheDivisionofGovernmentalCoordination.A Corps of Engineerswetlandspermitwillmostlikelyberequiredforconstructionontheproposedprojectsite.A Title 9 Zoning permit from the Northwest Arctic Borough will berequired.A Plan Review permit from the State Fire Marshal is also required.Final stamped design drawings are required to be submitted for review and approval prior to construction. The new pipelines will be routed to the maximum extent practical within roadright-of-ways and on public property.Where existing site conditions prohibitrunningpipeswithintheroad,easements will be obtained. 7.0 SPILL RESPONSE Because the new facility will have oil storage tanks in excess of 660 gallons andwillreceivedeliverybymarinevessel,it will be subject to U.S.EnvironmentalProtectionAgencyandU.S.Coast Guard regulations.An Operations ManualandaLetterofIntentwillneedtobepreparedandsubmittedtotheCoastGuard. An Oil Spill Response Plan will need to be prepared and submitted to both theCoastGuardandtheEPA.The facility will also require preparation of a SpillPreventionContro!and Countermeasures (SPCC)plan.Spill response gear,including sorbent material,protective safety gear,and possibly containmentboomwillneedtobepurchased.The project will not use most of the existingtanksforpermanentstorage;therefore,several should be placed in the vicinity ofthenewtankfarmanddedicatedtocontingencystorage.The participants in theconsolidatedtankfarmwillneedtoagreehowtoappropriatelyshareresponsibilityandexpensesforenvironmentalcomplianceandspillresponse.Consideration should be given to establishing a fund based on a per gallonchargeforthroughput. 8.0 SCHEDULE Rigid insulation,thermal siphons,geotextile fabric,and other materials will need tobebroughton-site prior to spring breakup to allow construction of the pad beforeexistingsoilsthaw.This will require construction of an ice strip to allow flyingmaterialsinbyL-100 aircraft.The best time to do this would be in March.Initialsitepreparationandpadconstructionisestimatedatapproximately1week.If theborrowsiteisclearedofsnowbythefirstofMay,the fill material should be sufficiently thawed to allow excavation as soon as the snow is clear from the site,approximately June first.The pad will need to settle for at least 4 weeks prior toplacingtanks.Pipelines will be run,tanks modified,and other peripheral systemswillbeinstalledduringthistime.The new tanks will arrive by barge in earlyAugust.The entire facility should be complete and ready for operation by the endofSeptember. 13 Noorvik Bulk Fuel Consolidation &Upgrade November 30,1998 Concept Design Alaska Energy and Engineering To meet this schedule,the final design should be completed and submitted to theFireMarshallbyFebruary.Procurement is required to begin in February to allowmaterialstobeflowninontheicestripandtoensuretanksarefabricatedintimetocatchthefirstbargetoKotzebue. 9.0 COST ESTIMATE The construction cost estimate has 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 superintendent.The detailed construction cost estimate is included in Appendix A.The total project cost including all design,supervision,inspection,permitting,and a 20% contingency is estimated to be: e Consolidated Tank Farm $1,904,772 $4.95/gallon (385,000 gal.gross) e AVEC Opt.#1 -OldTanks $795,332_$4.60/gallon (173,000 gal.gross) e Total Cost -Option #1 $2,700,104 $4.84/galion e Consolidated Tank Farm $1,904,772 $4.95/gallon (385,000 gal.gross) e AVEC Opt.#2 -New Tanks $812,756 _$5.02/gallon (162,000 gal.gross) e Total Cost -Option #2 $2,717,528 $4.97/gallon The costs have been developed assuming the AVEC facility and theconsolidatedfacilityareindividual"stand alone"projects.Savings of over$100,000 could be realized through reduced overhead and mobilization byconstructingbothfacilitiesconcurrently. 14 APPENDIX A CONSTRUCTION COST ESTIMATES NOVEMBER 30,1998ALASKAENERGYANDNOORVIKCONSOLIDATEDTANKFARM ENGINEERING FORCE ACCOUNT CONSTRUCTION COST ESTIMATE
