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 these needs,a proposed project schedule,and a budget cost estimate for the project. The participants in this project are: e City of Koyukuk (City) e Yukon-Koyukuk School District (School) An initial site investigation was conducted on July 19,2001 by Craig Valentine of LCMF Incorporated,and David Lockard of Alaska Energy Authority.This investigation included inspections of the existing fuel systems and potential new tank farm sites,and a meeting with Vera Lestenkof (Village Administrator),and Jason Malamute (Council Member)of the City of Koyukuk.Phone interviews were later conducted with Gail Bourne,Maintenance Supervisor of the Yukon-Koyukuk School District. The existing fuel systems were found to be in poor condition,with various code deficiencies. Further,no retail dispensing of fuel oil is available in the community,forcing residents to travel to Galena to purchase fuel oil for home heating.In order to bring the community fuel systems up to code and meet the current and future demands,a new collocated tank farm and new fuel systems should be constructed. The proposed tank farm site is located adjacent to the existing City of Koyukuk gasoline tank farm,between the power plant and the river.The new tank farm will include fuel storage for both participants,on-site retail dispensing of gasoline and fuel oil,and fuel oil distribution to the power plant,washeteria,and School. The proposed usable fuel storage capacities for the new fuel system are 33,100 gallons of gasoline,68,600 gallons of fuel oil for the City (including the power plant and washeteria),and 14,700 gallons of fuel oil for the School.The storage capacity is intended to meet the foreseeable community needs for the next 10 years. The total estimated budget cost for the proposed project is approximately $1,608,536 based on a 2002/2003 construction schedule.This estimated budget cost includes facility design, construction administration,permitting,and development of regulatory plans,construction costs, and a 20%contingency.The resulting cost per gallon is $12.26/gallon.

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 these needs,a proposed project schedule,and a budget cost estimate for the project. The participants in this project are: e City of Koyukuk (City) e Yukon-Koyukuk School District (School) An initial site investigation was conducted on July 19,2001 by Craig Valentine of LCMF Incorporated,and David Lockard of Alaska Energy Authority.This investigation included inspections of the existing fuel systems and tanks and potential new tank farm sites,and a meeting with Vera Lestenkof (Village Administrator),and Jason Malamute (Council Member)of the City of Koyukuk.Phone interviews were later conducted with Gail Bourne,Maintenance Supervisor of the Yukon-Koyukuk School District. A.CONTACTS Additional information for this report was gathered from the following people: David Lockard Alaska Energy Authority (907)269-4541 Vera Lestenkof City Administrator (907)927-2215 Jason Malamute City Council Member (907)927-2215 Gail Bourne Yukon Koyukuk School District (907)474-9400x144 Tony Pfister Alaska Native Tribal Health Center (907)729-3549 B.APPLICABLE REGULATIONS AND CODES The design/operation of fuel systems is controlled by the following State and Federal regulations: e State of Alaska Fire and Life Safety Regulations (13 AAC 50) e 2000 International Fire Code as adopted by 13 AAC 50 e 2000 International Building Code as adopted by 13 AAC 50 e State of Alaska Oil and Hazardous Substances Pollution Control Regulations (18 AAC 75) LOMF Incorporated fAsubsidiaryofUkpeagvik.Imupiat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report I. e EPA Oil Pollution Prevention Regulations (40 CFR Part 112) e U.S.Coast Guard Facilities Transferring Oil or Hazardous Material in Bulk Regulations (33 CFR Part 154) The State of Alaska Fire and Life Safety Regulations has adopted the 2000 editions of the International Fire Code (IFC)and the International Building Code (IBC).The IFC establishes the primary design requirements for new bulk fuel facilities,including pipelines. The State of Alaska Oil and Hazardous Substances Pollution Control regulations Oil Discharge Prevention and Contingency Plan (C-Plan)apply to fuel systems that have a storage capacity of more than 420,000 gallons per Owner,or Operator. The U.S.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 aboveground tanks larger than 660 gallons,or which have an aggregate total capacity of more than 1,320 gallons.The FRP is a spill response plan for facilities that receive fuel from vessels with storage capacities exceeding 42,000 gallons.SPCC Plans must be in place,but not submitted or approved by the EPA,within 6 months of the start-up of a facility.The FRP must be submitted prior to the start-up of the facility. The U.S.Coast Guard Facilities Transferring Oil or Hazardous Material in Bulk regulations apply to fuel facilities 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 that addresses the procedures and equipment required for receiving or dispensing fuel at the facility to vessels.The Coast Guard requires that these two plans,and a Letter of Intent to Operate, be submitted to the Captain of the Port for approval prior to delivery of fuel. EXISTING FUEL SYSTEMS .GENERAL OVERVIEW The site investigation included an inspection of the following tank farms and fuel distribution systems: 1.City Fuel Oil Tank Farm 2.City Gasoline Tank Farm 3.School Fuel Oil Tank Farm LOMF Incorporated 2 A subsidiary of Ukpeagvik,Imupiat Corporation AUTOCADDRAWINGNAME:KOYUKUK-EFLP.DWGPLOTTINGDATE:10/02/01(15:54)FIELDBOOK(S):¥re AG phatesReyideeSOhepsSomeasEWNf!: #APY 'BY}eth ie .. ey?.as ' - 2 ¢ated273-1830852-8212{Sor}AsubsidiaryofUkpeagvikIfiupratCorporationAnchorage.AlaskaBorrow,AlaskaLOMFrt i.KOYUKUKBULKFUELUPGRADEKOYUKUK,ALASKACONCEPTUALDESIGNEXISTINGFACILITIESLAYOUTPLANoFai "aaeyISTARpmentMARINE #2 HEADER Same /=ALASKAmmENERGYAUTHORITY/AEAStateofAlaska|DepartmentofCommunityanAIDEARuralEnergyGroup813WestNorthernLightsBlvd.EconomicDeveioAnchorage,Alaska99503CHECKED BY:WWW DRAWN BY:DAR DATE:10/8/01 W.O.No:01-408 REVISION: PHOTOGRAPH BY:AEROMAP U.S.DRAWING NO. DATE OF PHOTOGRAPH:8/26/93 Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report Fuel oil is not currently sold to the public in the community.Residents typically travel to Galena by boat or snow machine to purchase 55-gallon barrels of fuel oil for use in their home heating systems. B.EXISTING FACILITIES LAYOUT A detailed description of each of these tank farms is as follows: 1.City Fuel Oil Tank Farm sebn| The City of Koyukuk currently leases four BIA style tanks from the Cje¥to store fuel oil for use in the Power Plant and Washeteria.The tanks are located in the School's tank farm,located at the west end of the School.See the Existing Facilities Layout Plan for more information. The City tank farm includes four BIA style tanks located in an unlined,earthen diked,containment area,which is shared with School bulk tanks.The total shell capacity of the City tanks is approximately 34,800 gallons. Fuel is received at a marine header located near the shore of the Yukon River and pumped through a 3-inch,aboveground and buried,pipeline that is shared with the School tank farm.The barge off-loading pipeline is approximately 1,000-feet long.Fuel is drawn from the City tanks to the Power Plant through the barge off- loading pipeline by an automatic day tank located in the Power Plant.Fuel is pumped to the Washeteria tank using a garden hose. The tanks are in poor to fair condition,and the secondary containment area is not adequate.The above ground portions of the barge off-loading pipeline were observed to be in fair condition,however,the marine header lacked adequate secondary containment. 2.City Gasoline Tank Farm The City currently owns and operates the community's only retail gasoline dispensing station.The gasoline tank farm is located 200 feet southeast of the school,between the Power Plant and the river,on Vista Road (see the Existing Facilities Layout Plan). The tank farm consists of two 10,000-gallon,single walled,horizontal tanks.The tank farm total shell capacity is 20,600 gallons of gasoline.The tanks sit in a lined secondary containment area surrounded with earthen dikes.The containment area does not appear to be liquid tight. LOMF Incorporated | 3 A subsidiaryofUkpeagvik Imupiat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report Gasoline is received from a marine header located next to the City/School fuel oil marine header.The marine header lacks adequate secondary containment.Fuel is off-loaded through a 2-inch pipeline,which runs approximately 400 feet from the marine header to the gasoline tanks.Gasoline is dispensed through a dispenser located approximately 35-feet from the tanks. The tanks were noted to be in good condition,however,they do not have integral saddles.The piping was noted to be in fair condition. 3.School Fuel Oil Tank Farm The Yukon-Koyukuk School District owns a tank farm located behind the School, roughly 800 feet northwest of the Yukon River.See the Existing Facilities Layout Plan for more information. The School uses four of the eight BIA style tanks located in the tank farm,with the others used by the City,as identified above.The Schoo!tanks have a total shell capacity of approximately 21,800 gallons.The tanks are located in two containment areas that are surrounded by earthen dikes.Only the southern containment area is lined.The northerly containment area,which includes the City fuel oil tanks,is not lined. Fuel oil is received through the same barge off-loading pipeline used by the City. Fuel from the School tanks is pumped to a 300-gallon intermediate tank,located adjacent to the School building,using a pump located at the intermediate tank. Fuel is drawn from the intermediate tank to the School,back-up generator,and teacher housing units.The School uses waste heat from the Power Plant for primary heating and fuel oil heating as a back-up. The tanks were noted to be in fair to poor condition.The piping was noted to be in poor condition. C.EXISTING TANK STORAGE CAPACITY SUMMARY The following table lists the existing total tank shell storage capacity for all of the tanks currently in use.The usable capacity is calculated as 90%of the total shell capacity for bulk storage tanks and 85%for dispensing tanks.

Jason Malamute estimated that the City uses 30,000 gallons of fuel oil per year in the Power Plant,Washeteria,Clinic and City Office.Power Cost Equalization (PCE) program records for the Power Plant indicate an average fuel oil consumption of around 24,000 gallons per year.See the PCE records in Appendix A. LOMF Incorporated | 5 A subsidiary of Ukpeagvik:Iruplat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report The Yukon-Kuskokwim School District provided four years of fuel consumption information.The information indicates that the School uses an average of 3,200 gallons per year when waste heat is recovered from the Power Plant.The annual fuel consumption when waste heat is not available appears to be around 13,000 gallons (12,800 gallons used in 2000).See appendix A. There is no retail sale of fuel oil in Koyukuk.Residents purchase fuel oil in Galena and transport it back to Koyukuk for home use.Jason Malemute estimates current usage to be 200 gallons per household per year,which equates to 8,000 gallons of residential heating oil per year for the 40 houses in the community.This amount of fuel is lower than expected for home heating in this region,possibly due to the difficulty in getting the fuel and the alternative use of wood heat. The City fills its two gasoline tanks in late September.The fuel runs out in April.This averages Out to 2,833 gallons per month through the winter months.No summer gasoline usage data was provided.Using the winter usage rate throughout the year,the city would use 33,600 gallons of gasoline per year (2,800 gallons/month x 12 months). 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 User (gallons)(gallons) City 30,000 33,600 School Tank Farm (School Tanks)13,000 Home Heating Oil 8.000 51,000 33,600 E.PROJECTED FUTURE FUEL USE Census data over the past 10 years indicates that the population of Koyukuk is decreasing.The population dropped from 126 in 1990 to 101 in 2000.Given this slow general decline in population,and no significant infrastructure additions (which will increase fuel consumption)currently identified for the community,only a minimal expansion in fuel storage capacity is anticipated to be required. An increase of 10%of usable fuel storage capacity is included for the Power Plant,while the School's fuel consumption is anticipated to remain steady for the next 10 years. It is estimated that the fuel oil consumption would rise from the currently estimated annual amount of 200 gallons per household to 800 gallons as a result of the fuel being easier to purchase.It is assumed that the use of wood stoves would continue,off-setting LOMF Incorporated | 6 A subsidiaryofUkpeagvik Irupiat Corporation' Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report some fuel use.The resulting annual amount of fuel used for home heating would be 32,000 gallons (40 homes x 800 gallons/year).Since this usage is a significant increase over the current usage,it is assumed that this projection will cover the next ten years of demand. Retail sales of gasoline are estimated for yearly consumption.If the demand increases, additional fuel deliveries during the summer could provide an increase of up to 50% through the winter. Considering the factors outlined above,the resulting projected future fuel storage requirements are identified in the following chart. Projected Future Fuel Storage Requirements Fuel Oil Use Gasoline Use User (gallons)(gallons) City Facilities 33,000 City Retail Sales 32,000 33,600 School 13,000 Total 78,000 33,600 Ill.PROPOSED NEW FACILITY AND REFURBISHMENTS The existing facilities are in poor condition with various code violations.A new collocated tank farm and new distribution systems are recommended to replace the existing fuel systems. The proposed new fuel facility is a bulk tank farm,which will include bulk fuel storage for the City and the School.The new facility will include retail dispensing of gasoline and fuel oil,new intermediate tanks at the Power Plant,Washeteria,and School,new distribution system to the intermediate tanks and new barge off-loading pipelines/marine headers for gasoline and fuel oil. A.SITE SELECTION The new tank farm site is located south of the existing City Gasoline Tank Farm on the same property.(See the Project Layout Plan in Appendix D for more information).The site is bounded by Vista Road to the west,the Airport Road right-of-way to the south and an overhead power line to the east.The property is apparently owned by the City of Koyukuk,as identified in the Certificate to Plat contained in Appendix B. The proposed site is a large tract of land.In order to obtain site control for the project, the tank farm site should be subdivided.The resulting tank farm lot would have to be sized to allow for the large gravel pad that is required,IFC setbacks,and separations between the tanks and adjacent property.In addition,easements for both barge off- loading access and distribution pipelines will be required. LOMF Incorporated | 7 A subsidiaryof Ukpeagvik Inupiat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report B.SOIL CONDITIONS The tank farm site is on level ground set back 300 feet from a cut bank of the Yukon River.The area is heavily overgrown with undergrowth and trees which indicates that the ground is not underlain with permafrost.The soils are anticipated to consist of river deposited silts of varying depths,possibly overlying gravels or sands. A complete geotechnical investigation should be performed prior to completion of the tank farm design,to verify the actual site conditions and design assumptions. C.COMMUNITY FLOOD DATA The U.S.Army Corps of Engineers -Flood Plain Management Services ALASKAN COMMUNITIES FLOOD HAZARD DATA June 2000 publication has established the recommended building elevation at 17.7 feet,one foot above the flood of record in 1963. Floodwater depth at the laundromat was 7 feet.There is a reference flood gauge posted at the laundromat. Flood depths of up to 12 feet are anticipated at the tank farm site. The new tank farm should be built up to be above the flood level in order to mitigate tank floatation problems.The intermediate tanks will have to be anchored to address buoyancy issues. D.LOCAL FILL MATERIAL Fill material is available near the community.The material site is a sandstone and shale quarry located approximately *%mile from Koyukuk,near the cemetery.Gana-a'Yoo Corporation owns access to the site;however,the regional Corporation Doyon Ltd holds the subsurface mineral rights.A royalty fee may be imposed by Doyon for mining of the fill material. E.TANK FARM FOUNDATION DESIGN As stated above,the tank farm site appears to have river deposited silty soils and deep flood depths.The use of a deep gravel fill pad is proposed to economically raise the tank farm above the flood level.The construction of the fill pad will likely result in some initial settlement and may experience long term settlement as moisture slowly drains from the silty materials.Depending upon the depth of the silt layer,it may be necessary to preload the tank farm pad to minimize settlement once the tank farm is constructed. The tank farm pad is assumed to have to be built up roughly 12 feet above the existing ground level using local fill material.The pad side slopes would be sloped at 2.5:1 for LOMF Incorporated 8 A subsidiary of Ukpeagvik.Inupiat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report F, stability.A gravel access ramp will also be required for the installation of the tanks.See the Conceptual Design Drawings in Appendix D for more detail. SECONDARY CONTAINMENT In an effort to minimize the amount of gravel required to construct the 12 foot deep gravel pad,the foot-print of the tank farm containment dikes should be minimized.A lined timber dike system is recommended.See the Conceptual Design Drawings in Appendix D. The secondary containment area must be designed to contain the volume of the largest tank in the containment area,with additional capacity to address the displaced volume from other tanks in the containment area and to provide sufficient freeboard to allow for snow and precipitation accumulation.A minimum of six inches of freeboard should be provided for this facility. In consideration of the different fuel users'responsibilities and liabilities,the City and School tanks will be located in separate secondary containment cells.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. .TANKS The existing tanks are in excess of 10 years old,in relatively poor condition,are not code compliant,and cannot be made code compliant cost effectively,particularly when compared to installing fewer,larger,new tanks. The proposed tank farm has been designed around installing new 25,000-gallon, horizontal,single walled,bulk tanks,which have a net storage capacity of 22,700- gallons,and 12,000-gallon single walled and double walled,horizontal tanks,which have a net storage capacity of 10,400-gallons when used for dispensing tanks and 11,000- gallons when used for bulk storage. (Note:The net storage capacity is determined as 90%of the tank's shell capacity for bulk storage,and 85%of the tank's shell capacity for dispensing tanks.Net capacity is the amount of usable fuel which can be safely stored in the tank,excluding fuel below the issue nozzle and the top 5%of the tank which should be left empty to account for thermal expansion.) Horizontal tanks were chosen over vertical tanks to allow the City of Koyukuk the opportunity to relocate these tanks at such time when the City is able to move to higher ground. LOMF Incorporated | 9 A subsidiary of Ukpeagvik Inuptat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report The single walled dispensing tanks must be installed a minimum of 50'from the dispenser and public right-of-ways,and 75 feet from other properties which can be built upon.In addition,all penetrations must be through the top of the tank. As shown on the Conceptual Design Drawings,the proposed tank farm will have three new 25,000-gallon tanks (two for bulk fuel oil and one bulk gasoline)and two 12,000- gallon dispensing tanks (one for gasoline and one for fuel oil)for the City of Koyukuk. The School will have one new 12,000-gallon tank for the School's fuel storage. In addition to the tanks located at the tank farm,the proposed design includes a new 12,000-gallon double walled intermediate tank at the power plant,a new 4,000-gallon double walled intermediate tank at the school,and a new 2,000-gallon double walled intermediate tank at the washeteria. 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: Proposed Fuel Storage Capacities Tank Vert Size Fuel Oil (Gal)Gasoline (Gal) No.Owner __Purpose /Hor _LxWxH Total Usable Total Usable City of Koyukuk Tanks 1 City Disp H 10'dia x 21'12,300 10,400 2 City Disp H 10'dia x 21'12,300 10,400 3 City Bulk H 12'dia x 30'25,300 22,700 4 City Bulk H 12'dia x 30”25,300 22,700 5 City Bulk H 12°dia x 30”25,300 22,700 6 City Int H 10°dia x 21'12,300 11,000 7 City Int H §.3°diax 12.1'?2.000 _1,800 City Tanks Sub-Total=77,200 68,600 37,600 33,100 School Tanks 1 School Int H 10°dia x 21”12,300 11,000 2 School __Int H 6.4°diax 17.0'4,100 3,700 School Tanks Sub-Total=16,400 14,700 GRAND TOTAL=-93,600 =83,300 37,600 33,100 The existing tanks,which are not to be incorporated into the new consolidated fuel facility,or further used for spill response contingency,shall either be demolished and disposed of,or salvaged and removed from the community. LOMF Incorporated | 10 A subsidiary ofUkpeagvik Imupiat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report H.FUEL DISTRIBUTION The new bulk tank farm will include fuel storage for retail dispensing,power generation, and facility heating. 1.City Power Plant and Washeteria The Power Plant and Washeteria fuel distribution system will include a new transfer pump and pipeline to transfer fuel from the bulk tank farm to the new intermediate tanks.Fuel will be drawn into the Power Plant from the new intermediate tank using the existing automatic day tank in the Power Plant. Fuel transfers to the intermediate tanks 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: antisiphon valve float actuated fill limiting valve high level pump shut-off switch critical high level alarm and system shut-down liquid level gauge whistle vent emergency shut off (kill)switch The Power Plant and Washeteria fuel distribution pipeline will be constructed using new,Schedule 80,welded,steel pipe. 2.Retail Dispensing Retail fuel sales,including dispensing to motor vehicles,will be conducted through a gas station style dispenser located at the tank farm.The dispenser will be installed in a fenced enclosure with a roof.Fuel will be pumped to the dispenser using submersible pumps located in the dispensing tanks. 3.School/Teacher Housing The new School intermediate tank will be filled from the School's bulk storage tank,located in the tank farm,through a new distribution pipeline and submersible pump installed in the bulk tank.The intermediate tank will be connected to the existing School and teacher housing fuel systems. LOMEF Incorporated | | 11 A subsidiaryofUkpeagvik.Inuptat Corporation \ Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report Fuel transfers to the intermediate tank 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: antisiphon valve float actuated fill limiting valve high level pump shut-off switch critical high level alarm and system shut-down liquid level gauge whistle vent emergency shut off (kill)switch antisiphon valve The existing School distribution pipeline will be replaced.The new distribution piping shall be constructed using Schedule 80,welded,steel pipe. 4.Marine Header and Pipeline The existing marine header will be replaced with a new marine header and an 84- gallon steel plate secondary containment on a foundation.Two new 3-inch aboveground pipelines will be installed for barge off-loading of gasoline and fuel oil to the new tank farm from the marine header.The pipelines will be constructed using schedule 80,welded,steel pipe. I.OWNERSHIP AND OPERATION The proposed consolidated tank farm is designed to maintain both physical and legal separation between the two different entities,(City of Koyukuk and School).Each entity's fuel tanks are isolated in their own secondary containment cell and the fuel systems are isolated from one another. It is assumed that the City will own the tank farm and lease the one storage tank to the School. J.SPILL RESPONSE REGULATORY PLANS The presence of one entity responsible for the overall condition of the tank farm will allow for the preparation of one set of spill response plans for the entire facility.These plans will include 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,and a U.S.Coast Guard Operations Manual and Oil Spill LOMF Incorporated | | 12 A subsidiaryofUkpeagvik Inupiat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report Response Plan.Since the facility will have less 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; The US Coast Guard Operations Manual and Oil Spill Response Plan must be submitted,and approved,with a Letter of Intent to Operate,prior to receiving fuel. K.PERMITTING Typical permitting requirements for new tank farms and fuel distribution systems include submittal of construction documents to the State Fire Marshal for review and approval, and obtaining a U.S.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 The US Army Corps of Engineers is in charge of reviewing applications and issuing permits for the placement of fill in wetlands.Specific provisions have been established as a General Permit to address the construction of tank farms in Alaska.As a result,facilities which meet the requirements of the General Permit can take advantage of an expedited review process which reduces the review period from approximately 120 days down to 15 days. 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. LOMF Incorporated | 13 A subsidiaryofUtpeagetk:Inuplat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report Traditionally,Force Account projects have enlisted the use of local equipment where available.al equipment use cannot be donated to the project,equipment rental rates are negotiated or traded off for equi epair.\a ae!¢ 1.Local labor The City of Koyukuk was questioned about the local available labor force.They indicated that there are three certified welders in the City and a number of heavy equipment operators. 2.Local Equipment There is limited amount of running construction equipment in the community. The operating equipment identified is one dump truck (a second dump truckCocke)a Case W20C loader,and a Deere 450 bulldozer owned by the City ofRoyukuk. M.SCHEDULE The construction of the new tank farm and distribution systems is anticipated to take two summer construction seasons to complete.The first season will include the construction of the gravel fill pad with additional preload material.This pad will have to sit through the winter to allow the underlying soils to settle before construction of the tank farm. The second season will include the construction of the new tank farm,intermediate tanks, and pipelines. The following Construction Schedule is based on starting the design in the winter of 2001/2002. |{0 __Task Name {set |Frisn Bee Jan Feber [A [May ain |A TAup"Sep|Oct |Nov]Dec |Jan {Feb T Mar TApe [May Jun |sd”Aug |Sep[1"Design 4M 3/31 : [2”Earthwork bidding 4A 4/30 [3°|Gravel pad construction 6/3 8/30 ZZ.4 Procurement 10/1 11/30 ZZ5Z|Tank farm &distribution system construction 6/2 8/31 : §Receive fuel in new tank farm 9/1 9/1 LOMF Incorporated { 1 4 A subsidiaryofUkpeagvik Inupiat Corporation Koyukuk,Alaska DRAFT Bulk Fuel Upgrade Conceptual Design Report N.BUDGET COST ESTIMATE A Budget Cost Estimate has been prepared for the project as identified above,(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 Alaska.This estimate includes design cost,construction costs,regulatory plan development costs, project management costs and a construction contingency of 20%.
