Nunapitchuk Bulk Fuel Upgrades June 30, 2000
State of Alaska Department of Community and Economic Development Alaska Energy Authority,Rural Energy Group PRELIMINARY DESIGN REPORT 4S BIASeteeeeJail NUNAPITCHUK BULK FUEL UPGRADES June 30,2000 Prepared by: Wiley W.Wilhelm,P.E. LCMF Incorporated A subsidiary of Ukpeagvik inupiat Corporation 139 East 51st Avenue Voice:(907)273-1830 Anchorage,Alaska 99503 Fax (907)273-1831 Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report EXECUTIVE SUMMARY This report has been prepared for the State of Alaska Department of Community and Economic Development,Alaska Industrial Development &Export Authority,Alaska Energy Authority Rural Energy Group.The purpose of this report is to provide the basis for development of a new fuel system design and to identify construction scheduling and costs related upgrading the fuel systems in the community of Nunapitchuk,Alaska. The participants in the proposed fuel system upgrades includes: City of Nunapitchuk (City) Lower Kuskokwim Schoo!District (LKSD); Alaska Village Electric Cooperative,Inc.(AVEC),and; Nunapitchuk Limited Corporation (NLC). As part of the development of this report,a site investigation was performed on February 4, 1998.During this investigation potential tank farm sites were inspected,the existing fuel systems and tanks were inspected and a meeting was conducted with the City of Nunapitchuk Administrator,Eli Wassillie. As a result of the findings of the site investigation,and the subsequent geotechnical investigation,one new consolidated tank farm site was identified in the community for the City, LKSD Elementary School and AVEC Power Plant fuel storage.The NLC facility was identified to remain at its present location,with a new tank farm built adjacent to the existing facility. The new consolidated tank farm in the community will consolidate bulk storage for the City Water Plant,LKSD Elementary School and AVEC Power Plant.The new tank farm will be constructed on a pile supported steel platform with an integral steel dike.No dispensing of fuel will occur at the consolidated tank farm,instead,separate distribution system will transfer bulk fuel to intermediated tanks located at each of the facilities.A new 2,000 gallon double wall intermediate tank will be installed at both the Water Plant and Elementary School,while a 10,000 gallon double walled tank will be installed at the Power Plant.New automatic day tanks will also be installed in the Water Plant and Elementary School to replace existing elevated external day tanks. The new NLC tank farm will provide on-site retail dispensing of gasoline and fuel oil using a retail style dual product dispensing pump located in a secure enclosure near the existing dispensing station on the shore of the Johnson River.Since the community has not traditionally operated a tank truck,nor is one available in the community,the construction of a truck filling station is not included in the Conceptual Design. The Conceptual Design includes the reuse of all the bulk tanks currently located in the existing tank farms.The AVEC facility is to be supplemented with new 10,000 gallon vertical tanks while the NLC tank farm will be supplemented with new 30,000 gallon horizontal tanks. aLOMFIncorporatedEX-1 A subsidiary of Ukpeagvik Inupiat Corporation Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report The proposed usable fuel storage capacities for the new fuel system are 10,800 gallons for the Water Plant,87,000 gallons of gasoline storage and 100,800 gallons of fuel oil for the NYC, 50,000 gallons for the LKSD facilities and 136,100 gallons for AVEC Power Plant.These capacities will provide an increase in fuel storage capacity of approximately 35%over the current annual usage.The additional storage capacity will allow for an increase in fuel consumption of roughly 1.5%annually over next 20 years for the City,NYC,LKSD and AVEC facilities. Due to the scale of the project,and the fact that the two tank farms are separated by the Johnson River,a two season construction schedule has been developed.By constructing the tank farms sequencially,duplication of equipment and manpower can be eliminated without increasing the construction costs.Stretching the construction over two seasons will also lessen the impact on local resources such as local labor and housing. The total Budget Cost Estimate for the project is approximately $5,140.000.The resulting cost per usable gallon of storage is $11.28/gallon. A breakdown of cost per participant is as follows: City/LKSD $526,647 AVEC $2,618,647 NLC $1,997,292 Total $5,142,564 The estimated budget cost includes facility design,construction administration,permitting, development of regulatory plans,construction costs and a 20%construction contingency.

This report includes a review of the existing bulk fuel systems in the community,an analysis of future fuel needs,a conceptual design for the replacement/upgrading of these facilities to meet future needs,a proposed project schedule and a budget cost estimate for the project. The participants in this project are as follows: City of Nunapitchuk (City); Lower Kuskokwim School District (LKSD); Alaska Village Electric Cooperative,Inc.(AVEC);and Nunapitchuk Limited Corporation (NLC). Wiley Wilhelm,P.E.,of LCMF Incorporated,performed a site investigation on February 4, 1998.The investigation included an inspection of the existing fuel systems,inspections of potential new tank farm sites and a meeting with Eli Wassillie,City Administrator. A.CONTACTS Additional information for this report was gathered from the following people: Harlan LaGare Corps of Engineers (907)753-2610 Jim Kohl Lower Kuskokwim School District (907)543-4821 B.APPLICABLE REGULATIONS AND CODES The design/operation of fuel systems is controlled by the following State and Federal regulations: State of Alaska Fire and Life Safety Regulations (13 AAC 50); 1997 Uniform Fire Code as adopted by 13 AAC 50; 1997 Uniform Building Code as adopted by 13 AAC 50; State of Alaska Oil and Hazardous Substances Pollution Control Regulations (18 AAC 75); EPA Oil Pollution Prevention Regulations (40 CFR Part 112); e US Coast Guard Facilities Transferring Oil or Hazardous Material in Bulk Regulations (33 CFR Part 154). The current State of Alaska Fire and Life Safety Regulations adopted the 1997 editions of the Uniform Fire Code (UFC)and the Uniform Building Code (UBC).The code requirements of the UFC establish the primary design requirements for new facilities. LCOMF Incorporated1AsubsidiaryofUkpeagvikInupiatCorporation Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report Il. The State of Alaska Oil and Hazardous Substances Pollution Control regulations,Oil Discharge Prevention and Contingency Plans (C-Plan),apply to fuel systems which have a storage capacity of more than 420,000 gallons per Owner or Operator. The US Environmental Protection Agency (EPA)regulations include two regulatory plans for fuel facilities:1)Spill Prevention Control and Countermeasures (SPCC)Plans and 2)Facility Response Plans (FRPs).The SPCC Plan identifies minimum fuel facility requirements for above ground tanks larger than 660 gallons,or which have an aggregate storage capacity of more than 1,320 gallons.The FRP is a spill response plan for facilities which are filled by marine vessel and which have a storage capacity of more than 42,000 gallons. The US Coast Guard Facilities Transferring Oil or Hazardous Material in Bulk regulations apply to fuel facilities that are capable of transferring fuel,in bulk,to or from a vessel with a capacity of 10,500 gallons or more.This regulation includes two separate plans,1)Oil Spill Response Plan and 2)Operations Manual.The Oil Spill Response Plan is a spill response plan similar to the EPA's Facility Response Plan and it outlines spill planning requirements.The Operations Manual is a plan which addresses the procedures and equipment required for transferring fuel to/from vessels at the facility.The Coast Guard requires these two plans,along with a Letter of Intent to Operate,to be submitted and approved prior to the start of fuel transfers. EXISTING FUEL SYSTEMS A.GENERAL OVERVIEW The site investigation included an inspection of the following tank farms and fuel distribution systems: City Water Plant Tank Farm; LKSD Elementary School Tank Farm; AVEC Power Plant Tank Farm; NLC Tank Farm.PwrThe LKSD High School tank farm was not included in the inspection,or this report,since it was designed and constructed in accordance with the applicable codes and regulations during the early 1990's.LCMF designed and inspected the completed tank installation at the time of construction. A subsidiary ofUkpeagvik Inupiat Corporation f7\\ 5 LCMF Incorporated (Kd)ba Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report B.EXISTING FACILITIES LAYOUT A detailed description of each of these tank farms are as follows: 1.City Water Plant Tank Farm The City provides potable water to the community through the Water Plant.This facility uses fuel oil to heat the Water Plant building and potable water.Fuel oil is stored adjacent to the building in the Water Plant tank farm (see the Existing Facility Layout Plan). The tank farm consists of two vertical tanks,which are manifolded together.The total shell capacity of the two tanks is approximately 15,400 gallons.The vertical tanks are located inside a wooden diked area,which is lined with a membrane liner.The liner was observed to be in poor condition.Fuel is pumped through a fixed pump located inside the containment area into a 300 gallon day tank located adjacent to the building.The fuel transfer is manually controlled. Fuel is received at the common marine header located on the east shore of the Johnson River between the Elementary School tank farm and the AVEC Power Plant.The fuel is then pumped through a common barge off-loading pipeline, which is shared by the City tank farm,the LKSD Elementary School Tank Farm and the LKSD High School tank farm,to a tee located at the southwest corner of the High School where the fuel is routed to the two tanks. The vertical tanks were found to be in fair condition.The barge off-loading pipeline is in good condition since it was installed at the time the High School tank farm was constructed.The distribution piping is threaded and in poor condition. 2.LKSD Elementary School Tank Farm The LKSD provides elementary education at the old BIA school.The Elementary School is located near the AVEC Power Plant to the west of the High School (see the Existing Facility Layout Plan).The Elementary School buildings and adjacent teacher housing buildings are supplied fuel oil from the Elementary School tank farm. Fuel is drawn from the Elementary School tanks into the water/sewer plant and back-up generator building by a fixed pump.The fuel is then pumped to four intermediate tanks located outside each buildings heating system. The tank farm consists of five vertical cylindrical tanks,which are manifolded together.The total shell capacity of the tanks is approximately 43,000 gallons.

Fuel is received at the common marine header located on the east shore of the Johnson River between the Elementary School tank farm and the AVEC Power Plant.The fuel is then pumped through a common barge off-loading pipeline, which is shared by the City tank farm,the LKSD Elementary School Tank Farm and the LKSD High Schoo!tank farm,to a tee adjacent to the Elementary School tank farm,where the fuel is routed to the five tanks. The tanks were noted to be in fair condition.The barge off-loading piping is in good condition since it was installed at the time the High School tank farm was constructed.The distribution piping uses threaded connections and it is in poor condition. 3.AVEC Tank Farm The AVEC Power Plant provides electricity to the community.The Power Plant tank farm is located south of the Elementary School (see the Existing Facilities Layout Plan).The generators are supplied with fuel from the AVEC tanks. The AVEC tank farm consists of twenty-two BIA style tanks.The total shell capacity of the tanks is approximately 184,100 gallons.The tanks are located in a timber diked secondary containment area,which is lined with an impermeable membrane liner.It is understood that fuel is drawn into a day tank inside the Power Plant using a fixed pump. Fuel is received at a marine header located at the west end of the tank farm,inside the containment area,which connects directly to the manifold piping. The tanks and piping appear to be in good condition. 4,NLC Tank Farm NLC operates a gasoline and fuel oil tank farm and dispensing station on the north shore of the Johnson River,opposite of the community,as shown on the Existing Facility Layout Plan. The tank farm consists of eight BIA style tanks and three horizontal tanks.The total shell capacity of the tanks is approximately 101,900 gallons.The facility has a shell capacity of 68,200 gallons of heating oil and 33,700 gallons of gasoline. The gasoline and fuel oil tanks are connected with separate threaded pipe manifolds which are plumbed to a retail style dispenser.The tanks sit on timber foundations set directly on the ground.The tanks are surrounded by a plywood LCMF Incorporated A idiary of Ukp ik Inupiat Corporati Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report frame dike.The containment area has no membrane liner or other means to provide an impermeable containment.The facility is not fenced. Fuel is received through separate marine headers.The gasoline header is located at the dike,while the heating oil header is located on the shore,roughly 75 feet beyond the dike.The headers connect to the manifold piping with threaded pipe. Fuel is dispensed to vehicles,boats and containers througha retail style dispenser located in a wooden shed adjacent to the containment dike. The tanks were noted to be in fair condition.The remainder of the tank farm equipment and piping is in poor condition.

Where consumption data was not available,fuel purchase information was requested.At least three years of purchase quantities was requested in order to address both fuel use trends and to address over/under ordering.See Appendix A for fuel record information gathered for these facilities.Fuel use information was provided for the LKSD facility, AVEC Power Plant and NLC Tank Farm. The fuel consumption and/or purchase data may not completely identify each facility's actual consumption.In some cases,a facility may purchase fuel from another when they run out,therefore,the facility which sells the fuel may show higher use than actually required,while others may not adequately identify the amount of fuel used.Some fuel sharing has occurred in Nunapitchuk,however,it is our understanding that these quantities of fuel have only been 1,000 or 2,000 gallons a year,just enough to get by with.Given these smaller quantities,no adjustment should be required to the annual fuel consumption records. Another factor to be considered when determining fuel use is rationing at retail facilities when fuel quantities run low.Obviously,rationing curtails sales and does not accurately reflect the village fuel demands.While difficult to quantify,rationing is estimated to offset 1,000 -2,000 gallons of gasoline sales annually.Heating oil rationing is understood to not have occurred due to inter-facility purchases as noted above. No Water Plant fuel consumption data was provided for this report,however,Eli Wassillie,the City Administrator,indicated that an 8,000 gallon tank would cover the City's fuel needs at the Water Plant. The LKSD Elementary School annual fuel consumption appears to be around 10,000 gallons per year,with additional fuel used for construction projects. Based on the issues identified above,the estimated current annual fuel consumption for the community is as follows: Estimated Current Annual Fuel Consumption Fuel Oil Use Gasoline Use Facility (gallons)(gallons) City Water Plant Tank Farm 8,000! LKSD Elementary School Tank Farm _'10,000 AVEC Tank Farm 190,000 NLC Tank Farm 75,000*71,300 295,000 71,300 1.Estimated consumption based on Eli Wassillie recommendation. 2.1997 delivery quantities with 3%annual growth factored in. 7 LCMF Incorporated (4d)A subsidiary of Ukpeagvik Inupiat Corporation eg Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report E.PROJECTED FUTURE FUEL USE The community of Nunapitchuk appears to be experiencing a slow steady increase in fuel oil and gasoline consumption due to general community growth. The City Water Plant's demand is a function of the village population.As the village continues to grow,it is anticipated that the Water Plant fuel consumption will increase similiarly.Since fuel consumption records were not available for this report,a historical average growth rate of 1.5%per year should be applied to the storage capacity to meet future demands.The resulting increase in storage capacity for a 20 year period is 35%. Future fuel consumption for the LKSD Elementary School and out-buildings is anticipated to remain constant for the near future,however,LKSD has requested that additional capacity for reserve/construction be maintained in the new storage facility. For this reason,a minimum of 22,000 gallons of storage capacity shall be provided.This amount is roughly 200%of the current facility consumption. The AVEC Power Plant fuel consumption records show a jump in fuel consumption in the mid 1990's.This jump is most likely due to the construction of a the large High School addition.Other variations in the consumption most likely reflect "warm”or "cold”winter seasons.No large building additions,other than seven new houses to be built by AVCP in 2001/2002,have been identified.Since the historical data does not show a consistent growth trend,the use of a historical rural average electrical demand growth rate of 1.5%should be applied.The resulting total growth for a 20 year period is 35%.This additional fuel storage capacity would Records for multiple year fuel purchases,and past consumption,were not available for the NLC retail sales.Given this lack of historical increases in consumption,it is not possible to project future growth without using an assumed growth rate.For the purpose of this report,a projected 1.5%annual growth rate is used for gasoline and fuel oil consumption.The resulting total growth,over a 20 year projected design life for the facility,is roughly 35%over the current use. Considering the factors outlined above,the resulting projected future fuel storage requirements are identified in the following chart.These volumes are based on an increase of 35%over the current storage capacity.

Ill.PROPOSED NEW FACILITY The community of Nunapitchuk is located on the south shore of the Johnson River.Due to the local dependence upon river access,most of the river front property in the community,which is accessible by boat,has been developed.As a result,there does not appear to be adequate space for relocating the NLC river front fuel dispensing station to the community side of the river. Therefore,this report proposes that a new NLC tank farm be located adjacent to the existing facility while the City,LKSD Elementary School and AVEC Power Plant tank farms remain located in the community. Since the City,Elementary School and Power Plant are centrally located,one consolidated bulk tank farm can provide fuel storage for each separate facility.Further,the City and LKSD have agreed to consolidate their facilities due to the symbiotic relationship between the Schools and the Water Plant. The new tank farm would provide bulk storage of diesel/heating oil with a new fuel distribution system and intermediate tanks at the user facilities.The new facilities should reuse the relatively new barge off-loading/distribution pipelines,which feed the school tank farms,where possible. A.SITE SELECTION In developing this report,the existing Water Plant,Elementary School,Power Plant and NLC tank farm sites were evaluated for reuse.A summary of the site conditions/restrictions for each site is as follows: City Water Plant tank farm site:The Water Plant tank farm is located at crossroads of the community center.As a result,the tanks are located in a high traffic area with little extra room for rebuilding or consolidating with the other tank farms.In addition,the tanks may be less than 100'from the community well,which violates the requirements for a Class B community water source. (0S. 9 LOMF Incorporated 2)A subsidiary of Ukpeagvik inupiat Corporation er, Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report LKSD Elementary School tank farm site:The existing Elementary School tank farm is located in a small area adjacent to the common property line with the AVEC tank farm. The existing site does not have adequate space to construct a new tank farm without building on top of the existing tank farm footprint,which,due to potential contamination issues,is not recommended. AVEC Power Plant tank farm site:The AVEC Power Plant tank farm is located adjacent to the Elementary School.The property is not large enough to construct a new tank farm without building a portion of it on top of the existing tank farm footprint,which appears to have degrading permafrost underneath (see the attached Geotechnical Investigation for more details). NLC tank farm site:The ground around the existing NLC tank farm site appears to be suitable for construction of a new tank farm.The new tank farm should not be constructed on any portion of the existing facility.The existing dispensing station site is the only suitable boat landing site near the tank farm and the new dispensing station could be located at the same site,however,if contaminated soils must be cleaned up, there is a potential that the dispensing station may have to be relocated,or temporarily removed. New Consolidated Tank Farm Site:Since the existing tank farm sites in the community were found to be unsuitable for new facilities,a central site was selected for the new consolidated tank farm.The proposed consolidated tank farm site is located on an un- subdivided portion of the community,located between the Elementary School,the sewage outfall lines and the existing community boardwalks (See the Proposed Project Layout Plan drawing).The site is understood to be owned by NLC.The site is relatively close to the Elementary School,Water Plant and Power Plant,and it is large enough to consolidate all three tank farms into one facility. In order to obtain site control for the consolidated tank farm site,a tract should be identified and either leased from the Corporation or purchased.In addition,an easement for barge off-loading pipelines and distribution pipelines should be created to ensure access for pipelines and construction/maintenance access.The resulting tank farm property would have to be sized to allow for the UFC setbacks and separations between the tanks and adjacent B.SOIL CONDITIONS A Geotechnical Investigation was conducted for this project,by Duane Miller and Associates (see Appendix B).The investigation included boring test holes and logging the soil information to develop foundation requirements for each of the sites identified above. The report indicates that the soils at the tested sites consist of silt,with silty sand inclusions,overlain with a peat/organic silt layer at the surface.Soil temperatures at all @)LCOMF Incorporated10AsubsidiaryofUkpeagvikInupiatCorporation Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report but the AVEC tank farm,indicate warm permafrost conditions.The permafrost at the AVEC tank farm site appears to be degrading,with a thawed zone below the active layer. Massive ice was encountered only at the consolidated tank farm site,however,ice was noted in the peat and silt at all other frozen sites. The sites with frozen soil are susceptible to thaw settlement by compression of the peat, organic silt,or silts,or by thawing of massive ice,where present.Design of foundations at these sites must prevent thawing of the underlying permafrost,or large thaw settlement may occur. Construction at the AVEC tank farm site is not recommended by the Geotechnical Investigation Report without addressing the degrading permafrost conditions. C.COMMUNITY FLOOD DATA The US Army Corps of Engineers -Flood Plain Management Services ALASKAN COMMUNITIES FLOOD HAZARD DATA June 2000 publication indicates that flood waters in the community may cover lower areas with small amounts of water.The 100 year flood has been identified as the 1972 flood caused by an ice jam on the Kuskokwim River,into which the Johnson River flows.The flood water depth was estimated to be roughly 1 foot below the Power House fuel tanks,which sit roughly 1 foot above the surrounding grade.Since the terrain in the community is relatively flat,flooding at both the consolidated and NLC tank farms is estimated to be negligible (See Appendix C). D.LOCAL FILL MATERIAL The soils in and around Nunapitchuk are composed of organics and silt.Suitable fill material must be barged in from Bethel or other borrow sites.The cost for imported fill material is estimated to be around $125/cy.This cost is higher than at other communities due to shipping constraints and the use of small lighterage to cross shallow sections of the Johnson River.Due to the shallow sections of the Johnson River down stream of the community,fill material deliveries is dependent upon the stage of the river,with the potential for long delays if the river is not running high enough. E.TANK FARM FOUNDATION As stated in Section B Soil Conditions,tank foundations must address thermal stability of the underlying permafrost.Due to the difficulties of lightering fill material to the village and moving the fill material to the tank farm site,a pile supported tank farm foundation is recommended. Pile supported tanks have been successfully used at the High School tank farm and in other communities,such as Atmautluak,where the tank farms are located away from barge access and the delivery of fill material requires the construction of an access road. l,ION 7 LCOMF Incorporated (2)A subsidiaryofUkpeagvik Inupiat Corporation \Tee” Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report This foundation system elevates the tanks using ad-freeze piling in permafrost areas. Typically,steel piles are used.The tanks are supported by a steel framework and integral steel plate secondary containment system,all of which are elevated above the ground. The raised tanks and secondary containment system allow blowing snow to blow under the structure,preventing snow drifts which contribute to thermal degredation of the underlying permafrost.See the Conceptual Design drawings contained in Appendix D for more detail. F.SECONDARY CONTAINMENT The pile supported tank farm incorporates an integral steel secondary containment system.The tanks are located in a diked area,which uses steel plate walls for containment.The joints in the steel plate dikes and floor are continuously welded to provide an impermeable containment area. In consideration of the different fuel user's responsibilities and liabilities,each fuel user's tank will be located in separate secondary containment cells,with the exception of the City and LKSD Elementary School tanks which will share a common secondary containment area.This will limit the impact of a spill in the tank farm to the responsible party's separate containment area,and not affect the other fuel systems. G.TANKS In general,the tanks at each of the facilities are in fair condition and suitable for reuse with some modifications to make the tanks meet the Uniform Fire Code requirements and to ensure that the tanks are suitable for use over the design life of the tank farm (20 years). Consolidated Tank Farm.As shown in the Conceptual Design,the proposed tank farm has been designed with reusing the existing tanks and supplementing the storage capacity with new 10,000 gallon vertical cylindrical tanks where required. The City fuel is to be stored in a refurbished Elementary School tank with a usable storage capacity of 8,600 gallons.In addition,a new 2,000 gallon double walled intermediate tank is to be installed at the Water Plant,bringing the total usable fuel storage capacity to 10,400 gallons. The Elementary School fuel will be stored in three refurbished tanks from the existing Elementary School tank farm.A new 2,000 gallon intermediate tank will also be installed at the Elementary School bringing the total usable storage capacity to 25,300 gallons. AVEC's bulk fuel storage will incorporate twenty-two refurbished AVEC tanks,one refurbished Elementary School tank,two refurbished City tanks and five new 10,000 gallon tanks.One new 10,000 gallon double walled intermediate tank will also be 12 Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report installed near the Power Plant,bringing the total usable fuel storage capacity up to 240,000 gallons. The usable storage capacity for AVEC is roughly 16,000 gallons lower than the projected 20 year demand for the Power Plant.The reason for this shortage is due to the high cost for adding steel platform space to add two additional tanks to the AVEC portion of the tank farm.This extra cost does not appear to be warranted at this time,especially when it is not likely that the missing 16,000 gallons of fuel will be required for 10 -15 years..If the Power Plant demand requires an additional 16,000 gallons gallons of storage capacity, it may be possible to add storage in the City/Elementary School containment area. Alternatively,increases in generator efficiency and alternative energy sources may also offset increased fuel usage. NLC Tank Farm.As shown in the Conceptual Design,the new NLC tank farm will refurbish and reuse all of the existing tanks,both vertical and horizontal.Additional storage capacity will be provided by installing new 30,000 gallon tanks.The resulting usable fuel storage will be 92,900 gallons of diesel and 80,600 gallons of gasoline. Reuse of the existing tanks results in a slightly low amount of usable diesel fuel storage © (92,900 gallons vs.96,100 gallons estimated consumption in the year 2020).Given the accuracy of estimating the future fuel demand,the three thousand gallon difference should not make any appreciable difference to facilities operation in the future.If additional fuel is required,mid-winter fuel deliveries are possible by trucking fuel up the river from Bethel. The amount of gasoline storage is roughly 15,000 gallons less than the anticipated future demand,but more than the current annual use.Space has been provided in the tank farm for the installation of a future 30,000 gallon tank to bring the total storage capacity above the projected future demand,but the tank is not included in this project since it would most likely sit empty for the next 5 to 10 years.If the facility were to require additional gasoline to make it through the winter before a new tank could be installed,winter deliveries from Bethel may be a cost effective means to meet the demand. Two existing 5,000 gallon tanks are to be refurbished as dispensing tanks,one for diesel and one for gasoline.The dispensing tanks will be located in the tank farm containment area while supplying fuel to the retail dispensers. A summary of the proposed fuel storage capacities (including the bulk storage tanks, dispensing tank and new intermediate tanks,as shown in the Conceptual Design Drawings),is as follows: Sy LCMF Incorporated Mwidary oft igvik Inupiat Corp13 Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report Proposed Fuel Storage Capacities Tank Vert Size Diesel (Gal)Gasoline (Gal) No.Owner __Purpose /Hor LxWxH Total Usable Total _Usable City 1 City Bulk V 11'diax 13.57 9,600 8,600 2 City Int H 64”dia x 12'2.000 _1,800 City Sub-Total=11,600 10,400 LKSD Elementary School 1 LKSD Bulk Vv 1i'diax 13.5'9,600 8,600 2 LKSD Bulk V 10'diax 13.5'7,900 =7,100 3 LKSD Bulk Vv 10.5°dia x 13.5'8,700 7,800 4 City Int H 64"dia x 12'2,000 _1.800 LKSD Elementary School Sub-Total=28,200 25,300 AVEC 1 AVEC Bulk Vv 10.5°dia x 13.2'8,500 7,700 2 AVEC Bulk Vv 10.5'dia x 13.2'8,500 7,700 3 AVEC Bulk Vv 10'diax 13.2'7,800 -_7,000 4 AVEC Bulk Vv 10'diax 13.2?7,800 =-7,000 5 AVEC Bulk Vv 9°dia x 13.2'6,300 5,700 6 AVEC Bulk Vv 9°dia x 13.2'6,300 5,700 7 AVEC Bulk Vv 9.5'dia x 13.2'7,000 6,300 8 AVEC Bulk Vv 11'diax 13.2'9,400 8,500 9 AVEC Bulk Vv 9.5'dia x 13.2'7,000 6,300 10 AVEC _Bulk Vv 10.5'dia x 13.3'8,600 7,800 11 AVEC |Bulk Vv 11'diax 13.8'9,800 8,800 12 AVEC Bulk Vv 11'diax 13.2?9,400 8,400 13 AVEC Bulk Vv 11'dia x 13.3 9,500 8,600 14 AVEC Bulk Vv 10.5'dia x 13.3'8,600 7,800 15 AVEC Bulk Vv 10'dia x 13.3'7,800 7,000 16 AVEC Bulk Vv 10.5'dia x 13.2'8,500 7,700 17 AVEC Bulk Vv 10.5'dia x 13.8'8,900 8,000 18 AVEC Bulk Vv 11'diax 13.8'9,800 8,800 19 AVEC |Bulk Vv 10.5°diax 13'8,400 =--7,600 20 AVEC Bulk Vv 10'dia x 13'7,600 6,900 21 AVEC |Bulk Vv 10.5'diax 13'=8,400 =7,600 22 AVEC Bulk Vv 11°dia x 13'9,200 8,300 23 AVEC Bulk Vv 9.5'°diax 13.5'7,200 6,400 24 AVEC Bulk Vv 9.5'dia x 13.75'7,300 6,600 25 AVEC Bulk Vv 10'dia x 13.75'8,100 =--7,300 LCMF Incorporated {14 A subsidiary of Ukpeagvik Inupiat Corporation Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report Proposed Fuel Storage Capacities (continued) Tank Vert Size Diesel (Gal)Gasoline (Gal) No.Owner Purpose__/Hor |LxWxH Total Usable Total _Usable AVEC (cont.) 26 AVEC Bulk Vv 11'dia x 14 10,000 9,000 27 AVEC Bulk Vv 11°dia x 14'10,000 9,000 28 AVEC Bulk Vv 11'dia x 14 10,000 9,000 29 AVEC Bulk Vv 11°dia x 14 10,000 9,000 30 AVEC Bulk Vv 11'dia x 14 10,000 9,000 31 AVEC _Int H 8'dia x 28”10,500 9,500 AVEC Sub-Total=266,200 240,000 NLC 1 NLC Bulk H 10'dia x 40'23,500 21,100 2 NLC Bulk H 12°dia x 36'30,500 27,500 3 NLC Bulk H 12°dia x 36'30,500 27,500 4 NLC Bulk H 12'diax 36'=30,500 27,5005NLCBulkVv9.5'dia x 13.8'7,300 6,600 6 NLC Bulk Vv 11'diax 13.8'9,800 8,800 7 NLC Bulk Vv 9.5'dia x 13.8'7,300 6,600 8 NYC Bulk Vv 10'dia x 13.8'8,100 7,300 9 NYC Bulk Vv 10'dia x 13.8'8,100 7,300 10 NYC Bulk Vv 10.5'dia x 13.8'8,900 8,000 11 NYC Bulk Vv 11'diax 13.8'9,800 8,800 12 NYC Bulk V 10.5'dia x 13.8'8,900 8,000 13 NLC Bulk H 8°dia x 13.7 5,100 4,600 14 NLC Bulk H 8'dia x 13.7'5,100 _4,600 NLC Sub-Total=103,200 93,500 89,600 80,700 Note:Usable capacity equals 90%of total tank shell capacity.

The existing small tanks,which are not to be reused,shall either be demolished and disposed of,or salvaged and removed from the community. 15 LOMF Incorporated A subsidiary of Ukpeagvik Inupiat Corporation @rl Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report H.FUEL DISTRIBUTION The proposed design provides retail sales of fuel only at the NLC facility.No fuel dispensing is to be provided in the community. The fuel for the Water Plant,Elementary School and Power Plant will be distributed to the respective user facilities through a permanent piped distribution system. 1.City Water Plant The Water Plant fuel distribution system will be separate from the Elementary School's distribution system.The Water Plant fuel distribution system will only feed the new 2,000 gallon intermediate tank located at the Water Plant.The fuel distribution system will include a fixed transfer pump,located at the tank farm, which will pump fuel through new piping to the intermediate tank.Fuel transfers will be manually controlled with a timer back-up,however,a high level switch in the intermediate tank will shut-off the transfer pump.The intermediate tank will be equipped with the following appurtenances: float actuated fill limiting valve; high level pump shut-off switch; critical high level alarm; liquid level gauge; whistle vent;and All new distribution piping outside the tank farm containment area shall be constructed using Schedule 80,welded steel pipe with suitable low temperature properties.All of the existing LKSD barge off-loading pipeline is of recent installation and suitable for continued use.See the Conceptual Design Drawings in Appendix D for pipeline routing. 2.LKSD Elementary School The Elementary School's fuel distribution system will be separate from the Water Plant's distribution system.The Elementary School's fuel distribution system will only feed the new 2,000 gallon intermediate tank located at the Elementary School.The fuel distribution system will include a fixed transfer pump,located at the tank farm,which will pump fuel through barge off-loading pipeline back to the intermediate tank.Fuel transfers will be manually controlled with a timer back-up,however,a high level switch in the intermediate tank will shut-off the transfer pump.The intermediate tank will be equipped with the following appurtenances: (on. 16 LOMF Incorporated (2)A subsidiary of Ukpeagvik Inupiat Corporation SZ Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report float actuated fill limiting valve; high level pump shut-off switch; critical high level alarm; liquid level gauge; whistle vent;and All new distribution piping outside the tank farm containment area shall be constructed using Schedule 80,welded steel pipe with suitable low temperature properties.All of the existing LKSD barge off-loading pipeline is of recent installation and suitable for continued use.See the Conceptual Design Drawings in Appendix D for pipeline routing. 3.AVEC Power Plant The Power Plant fuel distribution system will include a new transfer pump and pipeline to transfer fuel from the bulk tank farm to a new 10,000-gallon intermediate tank located adjacent to the Power Plant.The distribution pipeline will also be used for barge off-loading.Fuel transfers will be manually controlled with a timer back-up;however,the transfer system will incorporate redundant overfilling prevention measures.These measures include the installation of the following equipment on the intermediate tank: float actuated fill limiting valve; high level pump shut-off switch; critical high level alarm; liquid level gauge; whistle vent;and The Power Plant barge off-loading and distribution pipeline will be constructed using new Schedule 80 welded steel pipe with suitable low temperature properties.See the Conceptual Design Drawings in Appendix D for pipeline routing. 4.NLC Tank Farm The NLC fuel is to be distributed for retail sale.Retail sales include both container filling and motor vehicle filling.In order to meet the State regulations for dispensing fuel from above ground tanks to motor vehicles,an approved dispensing tank and dispensing station must be installed.The dispensing station must include the use of dispensing tanks and a gas station style dispenser. Dispensing to containers can be performed at a motor vehicle dispenser,if approved containers are used. 17 Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report I.OWNERSHIP AND OPERATION The proposed consolidated tank farm in the community is designed to maintain both physical and legal separation between the City/LKSD and AVEC.The two separate fuel systems are isolated in separate secondary containment cells and the fuel systems are isolated from one another.It is assumed that each user will maintain and operate their own fuel systems.It is understood that LKSD will operate the City's portion of the combined facility and their own system. The NLC tank farm stands alone and it will be owned and operated by NLC. J.SPILL RESPONSE REGULATORY PLANS AVEC traditionally maintains their own separate spill response plans and it is assumed that they will continue this practice at the new tank farm.Therefore,the City/LKSD will be responsible for their portion of the consolidated tank farm and fuel system and NLC will be responsible for their separate facility. The AVEC and NLC facilities will require an EPA Facility Response Plan (required for all tank farms with more than 42,000 gallon capacity filled from a vessel),an EPA Spill Prevention Control and Contingency (SPCC)Plan (required for tanks larger than 650 gallons),a US Coast Guard Oil Spill Response Plan,and a US Coast Guard Operations Manual (both of which are required for facilities which receive fuel from vessels with a capacity of more than 10,000 gallons.) The City/LKSD tank farm will not require an EPA Facility Response Plan,but it will need an EPA Spill Prevention Control and Countermeasures (SPCC)Plan and a US Coast Guard Spill Response Plan and Operations Manual. Since none of the facilities have more than 420,000 gallons of storage capacity,a State of Alaska Oil Discharge Prevention and Contingency Plan (C-Plan)will not be required. Regulatory Plan Implementation Schedule: The EPA Facility Response Plan must be submitted prior to receiving fuel; The EPA SPCC Plan must be in place within 6 months of facility start-up; e The US Coast Guard Operations Manual must be submitted,and approved,with a Letter of Intent to Operate,prior to receiving fuel. LCOMF Incorporated18AsubsidiaryofUkpeagvikInupiatCorporation S Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report K.PERMITTING Typical permitting requirements for a new tank farm and fuel distribution system, includes submittal of the construction documents to the State Fire Marshal for review and approval and obtaining a US Army permit to place fill on wetlands. 1.Fire Marshal Review The construction of the new tank farm and fuel distribution systems will require submittal of a complete set of construction documents to the State of Alaska, Department of Public Safety,Division of Fire Prevention (Fire Marshal)for plan review and approval.Typical review periods range from 2 -3 weeks. 2.US Army Wetlands Permit No US Army Corps of Engineers Wetlands Permit is required if the facility are constructed on pile foundations and no fill is placed on wetlands. L.CONSTRUCTION Construction of the new fuel facility is to be conducted using Force Account methods. Under qualified management,this construction method has traditionally produced cost effective results,fast construction schedules and increased local hire. When working on a Force Account basis,the project typically hires a qualified superintendent and local labor where available.Additional personnel may need to be brought in to supplement the local labor force for specialty trades,such as pipe welding and electrical installation. Traditionally,Force Account projects have enlisted the use of local equipment where available.Where the local equipment use cannot be donated to the project,equipment rental rates are negotiated or traded off for equipment repair. 1.Local labor NLC was questioned about the local available labor force.They indicated that no formal list was available which identified personnel and skills. 2.Local Equipment No local equipment was observed in the community for use on this project. LCMF Incorporated19AsubsidiaryofUkpeagvikInupiatCorporation Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report M.SCHEDULE A construction schedule for both the Consolidated tank farm and the NL tank farm has been prepared based on historical force account fuel construction methods and crew sizes. Both tank farms utilize ad-freeze piling and a steel foundation.This method of construction requires that the piling be installed during the winter,after the active layer of the ground has re-frozen,to ensure that the slurry around the piling freezes solid and to allow for equipment access on the tundra.The resulting construction season is reduced to only 4 months (January -April)for working on the tundra.By May all work will have to be conducted on the tank platforms or off of boardwalks. Since the tank farms are more than 2 mile apart,it does not appear feasible to construct both simultaneously with one crew and one set of equipment.Therefore,a two-season construction schedule has been developed to avoid over-loading the local resources. The following schedule details the estimated construction schedule for construction of the Consolidated tank farm in the winter of 2001/2002. 2002 Task Name Days |Start |Finish ea Oct [Nov |Dec |Jan |Feb |Mar |Apr |May [Jun |Jul [Aug |SepMaterialDelivery20d;9/1/01 |9/20/01EquipmentDelivery|44)9801]92801]@ Piling installation 60d)1/15/02 |3/15/02'Tank Farm Cont.Install}46d!2/15/02}4/1/02. |ConstructPipelines |«22d!3/1/02|3/22/02Refurbish/install Tanks |43d!3/15/02 |4/26/02'Manifold Piping"T $4:5/102)6/3/02" 'Apply Coatings T 45d:6/4/02 |7/18/02 'Mech Equip Installation |30d,@/t/02)6/30/02 'Equipment Demob.+""F ds 6/30/02 |6/30/02 Electrical Installation |31d!7/1102|7/31/02 Project Completion.1d)9/1/02)8/1/02 |Receive Fuel 1d}8/28/02|8/28/02 + [Equipment [Crane 273d |10/1/01|6/30/02"Loader SS *é <- sés:SC<i S|«10/4/01|G/BOIOZ__Skid Steer "T2973a)10/1701 |6/30/02|DrttRig |60d!1/15/02}3/15/02 @)LCOMF Incorporated20AsubsidiaryofUkpeagvikInupiatCorporation Nunapitchuk,Alaska Bulk Fuel Upgrades Preliminary Design Report The following schedule details the estimated construction schedule for construction of the Nunapitchuk Limited tank farm in the winter of 2002/2003. |2003 Task Name Days |Start Finish [Sep [Oct |Nov]Dec |Jan |Feb |Mar |Apr |May |Jun |Jul |Aug Material Delivery 20d,9/1/02 |9/20/02EquipmentDelivery1d;9/30/02 |9/30/02 r 1211103 |3/17/0345d 30d)3/18/03|4/16/03 '14d!417/03 |4/30/03 2id!417/03!§/7/03 Piling Installation =Yank Farm Cont.Install| [Construct Pipelines '| Refurbish/install Tanks_||(|'Manifold Piping 21d)5/1/03 |5/21/03 Apply Coatings === - -S«|--s28 d |5/22/03 |6/18/03MechEquipInstallation|21d)5/22/03]6/11/03ElectricalInstallation|30d!6/15/03]7/14/03 Equipment Demob.1d|6/30/03|6/30/03 |4d)715/03 |7/15/03ProjectCompletion Receive Fuel _(44>Si2e103 ( Sr29103 Equipment "Crane SS™S* * :CSSC |10/402 |6/30/03"==as ae ] Loader 273d)10/1/02 |6/30/03 pale ere = "Skid Steer -SS* *« S:=<CS«TA |VAY |G YOVO |aomonniee Drill Rig 43d!2/103 |3/15/03 Note:The proposed schedule is very dependent upon many inter-related factors,such as project start time,material availability and weather.If any of these items creates a delay, the project may run into the following season,which will increase the construction costs.

N.BUDGET COST ESTIMATE Budget Cost Estimates have been prepared for construction of the new consolidated tank farm and the new NLC tank farm (see Appendix E for the complete detailed estimate). The estimate was developed based on historical Force Account construction costs for recent tank farm projects in southwest Alaska.Equipment rental rates are based on historical rental rates for similar equipment.This estimate includes design cost, construction costs,regulatory plan development costs,project management costs and a construction contingency of 20%. The Budget Cost Estimate for the total project is approximately $5.14 million. The resulting total project cost per usable gallon is $11.28/gallon based on 455,800 gallons of total shell capacity (tank farm plus the new intermediate tanks).The construction cost breakdown is $10.74/gallon. far&.

To provide data for the proposed bulk fuel facilities,LCMF,Inc.has contracted Duane Miller &Associates to conduct a geotechnical exploration which included the collection and review of existing geotechnical information from the area,surface reconnaissance of the proposed area,drilling and sampling borings,laboratory testing and engineering analysis. Nunapitchuk 60°54'N 162°26'W *, WN ate ie ct This soil investigation was performed in accordance with our proposal to LCMF dated February 11,1999.The object of the soil investigation was to determine the soil and permafrost conditions at the four sites and to develop conclusions and recommendations regarding site grading and foundation design.During the investigation we consulted with Mr.Wiley Wilhelm,P.E., from LCMF.We were assisted in Nunapitchuk by Mr.Earl Chase,IRA . Administrator. LCMF-Nunapitchuk Fuel Duane Miller &Associates July 13,1999 Page 2 INVESTIGATION Existing data The investigation started with the collection and compilation of existing data from previous explorations in the village.A summary of each exploration follows: Duane Miller &Associates,Foundation Investigation,Nunapitchuk High School Addition,July 1991.This report presents the results of the geotechnical investigation performed for the addition to the secondary school.Four borings were drilled from 10 to 20 feet,three in the vicinity of the school and one approximately 400 feet south of the school.The borings indicated 1.5 to 3 feet of peat and ice underlain by ice-rich gray silt.Ground temperatures measured in the borings below 3 feet were between 28°F and 31.5°F,with the warmer temperatures measured in an area underlain by a deep snow drift. R&M Consultants,Inc.,Geotechnical Investigation and Foundation Recommendations,Nunapitchuk High School,March 1979.This report presents the results of the subsurface soils investigation and soil engineering - recommendations for the high school.Five borings were drilled to depths of 30 feet at the building site.The borings revealed 2.5 to 3 feet of peat and ice underlain by ice-rich gray silt.Sand was encountered at depths around 28 feet. Ground temperatures measured in one boring varied from 31°F at 5 feet to 28.5° F at 30 feet.The recommended foundation design called for timber piles placed in predrilled holes and backfilled with a sand-water slurry. Site reconnaissance On September 23,1998,Mr.Mike Hendee,project engineer for DM&A, traveled to Nunapitchuk in conjunction with a BIA boardwalk investigation in the village.Mr.Hendee probed the active layer with a 1/4-inch diameter steel rod to determine the depth of seasonal thaw.Seasonal thaw was found to extend to depths of 2 to 3 feet at the proposed sites for the bulk fuel facilities. Subsurface exploration We explored the area by drilling and samplinga total of five borings,one at each of the proposed sites.The exploration was performed from March 12,1999 through March 18,1999,under the direction of Mr.Hendee. LCMF-Nunapitchuk Fuel Duane Miller &Associates July 13,1999 Page 3 A Nodwell mounted CME 45 drill rig equipped with hollow stem augers and standard soil sampling tools was used for the exploration.The drill is owned and operated by Denali Drilling of Anchorage.The drill and tools were mobilized overland from Bethel. The borings were logged and sampled as they were drilled.The sampling was performed by grabbing samples off the auger flights or by advancing a 1.4- inch ID split barrel sampler below the bottom of the auger with a 140 pound manual hammer free falling 30 inches (Standard Penetration Test).Samples from the borings were sealed in moisture proof containers and returned to the laboratory in Anchorage.Closed,3/4-inch I.D.PVC pipe was left in each boring to allow for future ground temperature measurements. The locations of the borings were established by swing ties from existing structures identified from a site plan provided by LCMF.The boring locationsareshownonPlate2.The borings are summarized in the following table.

LCMF-Nunapitchuk Fuel Duane Miller &Associates July 13,1999 Page 4 SITE and SUBSURFACE CONDITIONS Site conditions Nunapitchuk is located approximately 26 miles west of Bethel in the Kuskokwim River Delta of the Yukon-Kuskokwim Lowland physiographic province.The region is underlain primarily by interbedded marine and terrestrial deltaic and eolian deposits.The main village is located in an oxbow of the Johnson River,approximately 22 miles from its confluence with the Kuskokwim River.The airport to the northeast and a subdivision to the northwest are located across the river from the main village.A vicinity map of the area is shown on Plate 1. A road connects the airport to the river.The road was constructed in 1997 and has settled into the tundra approximately 3 feet.The surface is constructed of imported gravel and appears to be contaminated with the subgrade.The thickness of the road prism is not known. The river is tidally influenced and subject to flooding during periods of high runoff.The land near the river is flat and poorly drained with grade changes of less than 15 feet.The vegetation along the river is primarily sedge and grass with small willow groves in the drainage areas of drained lakes.The north side of the oxbow,near the airport,consists of higher ground with moss covered tundra. The main village,inside the oxbow,is located on mostly low,wet,sedge covered ground with interspersed zones of higher,drier,grass covered ground. A few moss covered palsas are scattered southwest of the new sewage lagoon. The subdivision across the river is mostly located on higher,drier,grass covered ground with interspersed palsas.Northeast of the subdivision,toward the airport,is a large area of saturated ground interspersed with drainage sloughs. Climate The climate at Nunapitchuk is characterized as transitional maritime with cold winters and cool summers.Both the Johnson and Kuskokwim Rivers freeze in the winter.The chart on the following page shows the mean monthly temperatures and precipitation for 61 years of record for Bethel.

The silty sand was underlain by silt in Borings NUN-2 through NUN-4. All the borings were fully frozen to the depths explored except Boring NUN-3 near the AVEC tank farm where a talik of unfrozen soil was encountered from 2.5 to 7.5 feet.The talik is probably due to deep snow drifts in the vicinity that insulate the ground surface during the winter and deter freezeback.Based on the probes,the normal summer thaw extends to depths of 2 to 3 feet.When the surface soil is unfrozen,it is soft and highly compressible.Visible ice is present in the peat,organic silt and silt layers with massive ice encountered in Boring NUN-4 from 2 to 10 feet.The silty sand layer is well bonded with no visible ice. Moisture contents are high in the peat,organic silt and silt layers.The chart on the following page shows the moisture contents for each soil type versus depth.Moisture contents greater than 200%have been omitted for clarity.These higher moisture contents occur in the organic soils in the top 2 to 3 feet and range up to 715%.

Consequently,the degrading condition at NUN-3 should be avoided if possible or the site should be refrozen before it is used as a tank farm. Either an at-grade foundation system or a pile foundation may be used to support the fuel tanks and containment structure at the four well frozen sites. Either foundation system must be designed to prevent thaw of the permafrost.If the foundation is not designed to prevent thawing of the underlying permafrost, large thaw settlements will occur. At-grade foundation The four sites other than the existing AVEC tank farm are suitable to support a bulk fuel facility on an at-grade foundation.An at-grade foundation would require importing fill material and using insulation and horizontal __ thermal syphons to reduce the risk of thaw degradation of the permafrost.The at-grade system might experience some internal differential movements as the fill under the insulation freezes and thaws each year. Schematic of an At-Grade System . :Dike Membrane Radiator Fuel Tank(s)Fill Fuel Proof Membrane Insulation LayerAEEEEEEThermalSyphon@5%slope Fill To preserve the underlying permafrost,insulation is required in the fill material with passive thermal syphons beneath the insulation.The thermal syphons are a liquid vapor system manufactured in Anchorage by Arctic Foundations,Inc.,and remove heat from the ground in the winter with no moving parts (no fans or pumps).The fill pad is insulated with a continuous layer of extruded polystyrene board insulation.The thermal syphons are spaced close enough in the fill so that they fully refreeze the soil that thaws each LCMF-Nunapitchuk Fuel Duane Miller &Associates July 13,1999 Page 9 summer when they are not operating.The thermal syphons must be sloped so that condensate flows to the tip of the pipe. The thermosyphons should be spaced no more than 14 feet apart in Nunapitchuk.It is preferable to space the thermosyphons so that they underlie the tanks.The thermosyphons can be prefabricated to lengths of 60 feet and flown to Bethel.They can then bebent in the field to provide an effective length of 45 feet.If the pad is wider than 45 feet,thermosyphons will need to be placed on each side of the pad. The thermosyphons should be constructed of 3-inch diameter steel pipe and should have a radiator section with at least 70 square feet of area.The thermosyphons should be properly coated over their full length to prevent corrosion.The vertical section of the thermosyphons can be free standing using the 3-inch pipe.The thermosyphons will be protected from vehicle damage by the fill slope if the radiators are on top of the fill pad.The radiators should be temporarily braced and protected during completion of the fill placement.

The fill beneath the insulation layer is expected to thaw each summer when the thermosyphons are not operating.The depth of thaw depends on the air temperature,the thickness of insulation,the moisture content of the fill,length ofthesummerand.the amount of cooling provided each winter by thethermosyphons.A sand fill is preferable since it costs less than gravel and will hold more moisture,thus acting as a better heat sink. New fill should be placed as an overlay,without disturbing the existingorganicsubgrade.A layer of engineering fabric should be placed on thesubgradepriortotheplacementoffillsThefabricshouldbeMirafi500®or equivalent.Any unfrozen soil will compress,under the weight of the fill andadditionalmovementswillalsooccurwhen,the:organicand silty soil refreezesandheavesthefirstwinter.The effect ofthese movements can be reduced ifconstructionofthedikeandplacementofthetanksiis'deferred until after the firstwinter.However,this requires that the fill pad,insulation:and thermosyphons beconstructedinthefallandthetanksberelocatedthefollowingyear.petCross-Section of Foundation Pad':.

The available sand is fine grained and has a low bearing capacity at the surface.If the dike and tanks will be supported on beams resting on the surface of the fill,the spacing of the support beams will be controlled by the bearing capacity of the surface fill.Consequently,to allow a wider spacing of the beams, the sand fill should be reinforced.This will require either a 12 inch layer of coarse gravel at the surface or a 6 inch thick cellular confinement system in the sand fill. The insulation layer under the tank area should be 4 inches thick.The insulation should be a closed cell,extruded polystyrene such as Styrofoam®withacompressivestrengthofatleast40psi.The insulation is available in boards that are two-inches thick by two feet wide by eight feet long.The insulation should be installed in layers on a smooth,unyielding fill surface.The joints of each layer should be staggered.The insulation should be continuous under the tank area and should extend 5 feet beyond the dike perimeter. The insulation should be protected from spills of deleterious fluids by a fuel-proof membrane such as Permalon®with a thickness of at least 20 mil placed over the insulation.The membrane should extend at least 2 feet beyond the edge of the insulation.Permalon®can be purchased in large sizes and is relatively light so that field seaming,which is difficult,is not needed. Thermistors should be installed to monitor the thermal performance of the =ore = thermosyphons and insulation design.Fill insulation The thermistors should be installed as a Thermal Fill eo:Syphonsverticalarrayattwolocationsbelowthe3Thermistors containment dike.An additional ANASSA ADAADAATSthermistorarray,consisting of [ste Soil 4°12"deep Athermistors2and3only,should also be 12'to 14°cc installed at one edge of the dike,and,to monitor air temperatures,two _additional thermistors should be installed at the top of two radiators (one LCMF-Nunapitchuk Fuel Duane Miller &Associates July 13,1999 Page 12 apiece).The lead wires from the thermistors should be brought to a central location where they are terminated on a terminal strip inside an enclosure.The wires should be run without breaching the insulation or fuel proof membrane. The as-built locations and elevations of the thermistors should be carefully surveyed and recorded.Readings of the thermistors should be obtained at the time of installation and then fortnightly during construction and through the first year of operation. The thermistors should be an interchangeable type with an interchangeability tolerance of 0.1°C from 0°C to 70°C.The zero power resistance at 25°C shall be equal to or less than 5000 ohms.A YSI 44034 thermistor will be acceptable.They should be attached to and sealed in lead wires using soldering techniques and sealants that do not result in the temperature of the thermistor exceeding 75°C.The lead wires should be sufficiently long to allow for the installed position plus the length of wire needed to run to the readout position without penetrating the fuel-proof membrane.Each pair of lead wires should be marked with a distinct wire number.A certification of the methods used in the manufacture of the thermistor cables and an ice bath verification of the __ assembled cables should be provided before the thermistors are accepted. The plans and specifications should be reviewed by us to verify that they are in accordance with the intent of these recommendations.The placement and compaction of new fill,installation and backfill of the thermosyphons and insulation,and the placement of the thermistors should be inspected and tested by an experienced soils engineer.The temperature data collected during the first winter should be reviewed by us each month.Inspection will permit the detection of unanticipated conditions and allow verification that the work is done in accordance with the intent of the recommendations in this report. Pile supported foundation The ground temperatures at all but the present AVEC site are cold enough so that reasonable pile capacities can be achieved if the piles are installed in predrilled holes,backfilled with a sand-water slurry and allowed to freeze.Some movement will occur in the natural ground adjacent to the piles each year during freeze and thaw cycles.Therefore,piping that goes from the pile supported structure to the natural grade should be designed to tolerate about four inches of differential movement. LCMF-Nunapitchuk Fuel Duane Miller &Associates July 13,1999 Page 13 Steel pipe or timber piles gaining support from adfreeze bond in the permafrost appear to be well suited for foundation support.If timber piles are used,they should be properly treated to prevent decay.If steel pipe piles are used,the pipe should be sealed at its tip with a water tight,welded steel plate.If the tundra condition at the site is maintained,an active layer of three feet thick is expected for the site.The allowable sustained load capacity for 12-inch diameter steel pipe or round wood pilesis shownin the following chart.The capacity is based on the expected end of summer ground temperature profile.Piles deeper than 30 feet are not recommended since the local drills in Bethel are most economical to a 30- foot depth.

An unobstructed ventilation space needs to be maintained between the base of the containment structure and the ground to prevent degradation of the permafrost.The containment structure should be designed to cantilever out beyond the pile locations as much as feasible so that the piles will be shaded.If LCMF-Nunapitchuk Fuel'Duane Miller &Associates July 13,1999 Page 14 the piles are not fully shaded,they should be painted a reflective white to reduce the solar heat gain.The ventilation space should be at least three feet from the base of the structure to the ground surface._ The ground temperatures measured at the high school in Nunapitchuk show a moderately warm permafrost condition.The lower portion of the temperature curves suggest an average ground temperature of 31°F.If warming conditions occur at the site and require a future cooling system,thermosyphons may be installed directly in the steel pipe piles.If timber piles are used,a 3-inch diameter,closed steel pipe should be installed adjacent to the pile to allow for the insertion of a passive cooling system. The piles must be protected from frost heave forces or they will jack upwards.Each pile should be wrapped with three layers of 10-mil polyethylene film (visqueen)around the section of the pile in the active layer,i.e.,the top three feet.The bond of the frozen soil to visqueen is much less than the adfreeze bond to steel or wood.The visqueen is commonly called a "bond-break",but actually it just reduces the heave force;it is a "bond-reducer".The pile still has to have adequate dead load or penetration to resist the remaining heave force.Assuming that the piles could have light dead loads during freezeback of the active layer, the piles should be embedded a total depth of at least 25 feet below the ground surface. The piling should be installed in a hole drilled to a diameter about six inches larger than the dimension of the pile.The diameter of the hole should be large enough to allow proper positioning of the pile and the use of a concrete vibrator on all sides of the pile during slurry placement.The depth of the holeshouldbemeasuredtoverifythatthedesigndepthhasbeenachieved.The pile should be placed in the hole so that it is plumb and in proper position.The pile should be held firmly in place by blocking until the slurry is placed and fully frozen. | The slurry used for backfill should consist of a mixture of sand and potable water.The sand-water slurry should not be colder than 35°F nor warmer than 45°F at the time of slurry placement.Cuttings from the augured hole should not be used to make the slurry.To reduce the amount of water needed to achieve saturation,the sand should contain less than 20%material finer than the #200 sieve size.Fine grained silty sand suitable for making slurry is available in Bethel and New Kasigluk.Additionally,AK DOT&PF has mined a material site on a LCMF-Nunapitchuk Fuel Duane Miller &Associates July 13,1999 Page 15 bluff along the Johnson River for the Atmautluak airport.The material is similar to the Bethel or New Kasigluk dune sand. The annulus should be filled in lifts with the sand-water slurry.The slurry can be mixed either above grade in a concrete mixer or in the annulus of the hole. If the material is mixed in the hole,the water should first be placed in the hole and then the sand added.The sand should be added no faster than what can be thoroughly mixed.The water and sand should be placed in the hole so that at all times the surface of the sand is under water as it is mixed.As previously discussed,the sand should be unfrozen when mixed in the slurry.A concrete vibrator should be used continuously for the full depth of the hole as the slurry is placed. The slurry should be fully frozen and at a temperature of 31°F or colder before loads are placed on the piling.The time required to achieve this condition will depend on the ground temperatures at the time of slurry placement.If air temperatures are cold and steel pipe piles are used,the contractor can use low pressure,high velocity fans to force air down the pipe piles and thereby accelerate the slurry freezeback. To allow for the monitoring of slurry and pile temperatures,a closed 3/4- inch diameter solid PVC pipe should be installed adjacent to each pile.The temperatures along the piling can be monitored after construction using thermistors placed in the PVC pipe. To maintain its insulating characteristics,the ground surface should be protected from compaction,rutting and ponding during construction.Mats might be needed to protect the soft organic soils at the site if the construction occurs when they are unfrozen.At the end of construction,the ground surface should be left in a smooth condition.Any ruts or damaged tundra should be filled,patched and sloped to drain to the perimeter of the structure and revegetated. The plans and specifications should be reviewed by us to verify that they are in accordance with the intent of these recommendations.An experienced inspector should be present full time during the pile installation to observe and record the conditions found in the augured holes.Inspection will permit verification of the soil and permafrost conditions in addition to the proper installation of the piles.

The following elevations were based on a benchmark with an assumed elevation of 100.0 feet: Survey information: 100-year flood,or Base Flood Elevation (BFE)91.8 Recommended building elevation <92.8 Centerline of the runway at the taxiway 100.8 First floor of the high school 100.0 First floor of the Nicolai Berlin house 92.8 First floor of the washeteria 99.6 First floor of the grade school 98.0 First floor of the powerhouse 96.3 First floor of the city office 96.1 First floor of the clinic 95.6 Powerhouse fuel tanks 92.9 ice elevation of the Johnson River on 4/14/93 87.7 The 1972 flood surrounded Nicolai Berlin's house but did not reach the footings.Therefore,the flood height was assumed to be 1 foot below the topofthefirstfloorofhishouse.No high Water Elevation signs were placed since there was no suitable object at the flood level on which to place the mark.
