Representatives from AEA and CRW conducted a site visit to Perryville on October 13", 2010.During the site visit,AEA Project Manager Bryan Carey and CRW Engineer Karl Hulse met with NVP members and local fuel system maintenance staff,and toured the community's existing fuel storage and handling facilities. EXISTING CONDITIONS There are currently two bulk fuel tank farms in the Community.Tank farm #1,located approximately one mile southwest of the community,is owned and operated by the NVP.The facility consists of a lined earthen dike secondary containment area containing 2 unused vertical single-wall tanks (27,000 and 42,000 gallons respectively), 4 single-wall horizontal tanks (2 used for gasoline at 3,000 gallons each,and 2 diesel tanks at 20,000 and 10,000 gallon capacities),and 12 horizontal single wall tanks of varying capacity owned by local residents. Tank farm #2,located approximately 40 ft west of the school,is owned and operated by the Lake &Peninsula School District (LPSD).This facility includes three 7,500-gallon single-wall horizontal diesel tanks and a 500 gallon double wall dispensing tank. PROPOSED IMPROVEMENTS The proposed Perryville Bulk Fuel Upgrade Project includes construction of a new, 106,500-gallon,code-compliant bulk fuel tank farm,truck transfer secondary containment area and retail dispensing facility.The tank farm will consist of four horizontal,single wall ASTs (three 28,000-gallon diesel,one 13,500 gallon gasoline, one 3,000 gallon ULSD within a lined,earthen secondary containment dike. Other project components will include a 6,000-gallon dual product protected dispensing tank located near the power plant,a triple product barge header and fill pipelines,and all required spill contingency equipment and regulatory plans.The proposed facilities will be owned and operated by NVP,and will replace the existing,aged,non-code compliant bulk fuel storage and handling systems.The capacity of the proposed facility will meet residential heating,retail sales and power generation fuel demands for 13 months of the design year,a period sufficient to span the barge deliveries when weather prevents availability. Due to funding constraints,the LPSD is not a participant in the project. Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report ES-1 August 2011 The proposed project schedule,subject to funding,calls for design and permitting during 2011,with construction scheduled to begin in the spring of 2012. The total project cost,including all design,supervision,contract administration, construction,inspection,permitting and a 15-percent contingency,is estimated to be $1,406,000 which equates to a unit cost of $13.20 per gallon based on a gross storage capacity of 106,500 gallons.

Conceptual Design Report v August 2011 1.0 PROGRAM OVERVIEW The Alaska Energy Authority (AEA),Rural Energy Group is pursuing grant funds to upgrade rural bulk fuel tank farms.The following bulleted items provide a brief outline of the program: Most of the funds for the bulk fuel upgrades program are federal in origin,and are provided through the Denali Commission.Other federal funding sources may include Community Development Block Grants from the US Department of Housing and Urban Development (HUD)and/or grants from the Environmental Protection Agency (EPA).Additional funds may be available from the State of Alaska,through the Department of Environmental Conservation and the Department of Education. In order to receive grant funds,each community must demonstrate that the proposed facility will be sustainable by accepting a Business Operating Plan (BOP).The function of the business plan is to establish ownership of the facility's components,and describe how each component will be operated, maintained and,eventually,replaced. New tank farms are funded,designed,and constructed in three phases:Phase 1- Conceptual Design;Phase 2-Final Design;and Phase 3-Construction. During Phase 1 staff from AEA will visit the community,discuss the program,and work with residents and the local government to select a site for the new tank farm.All planning and decisions concerning the conceptual design will be summarized in a Conceptual Design Report (CDR)and draft BOP. At the completion of Phase 1 the community will be requested to review and approve the CDR and draft BOP documents. During Phase 2 the design and permitting tasks for the new tank farm will be completed.Other Phase 2 tasks will include preparing an environmental assessment,gathering site contro!documents,and finalizing the BOP for signing. Each community will be asked to provide "in kind”contributions to the project such as land for the new tank farm and free use of local heavy equipment.If local equipment is utilized,the project grant funds will pay for fuel,maintenance, and any repairs during construction. Projects may include local hire and construction trade training programs,subject to funding. Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 1 August 2011 e If construction funding is awarded then the project will advance to Phase 3,the final BOP will be sent to the community for signature,and a Construction Manager or Contractor will be selected to construct the project. e Ineligible Project Components:Funding is not available through AEA for buildings,propane facilities,fuel tank trucks or trailers,underground storage tanks,fuel to fill the tank farm,environmental remediation,operation & maintenance costs,or residential tank upgrades.Loans for fuel tank trucks and trailers may be available through the U.S.Department of Agriculture (USDA). e Training is Available:AEA has several training programs available for facility operators and managers;see Appendix E for further information. Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 2 August 2011 2.0 COMMUNITY OVERVIEW Perryville is located on the south coast of the Alaska Peninsula,approximately 275 air miles southwest of Kodiak.Local community organizations include the Native Village of Perryville (NVP)which also operates the local Electric Utility.Regional organizations include the Lake &Peninsula School District (LPSD)and the Oceanside Native Corporation (regional Native Corporation). The current population of Perryville is approximately 113 (2010 Census Population). The majority of residents within the Village are Aleut Alaska Natives. Based on the 2000 Census,there are 45 total housing units in the community,including 12 vacant structures. 3.0 SITE VISITS AND COMMUNITY INVOLVEMENT Representatives from AEA and CRW conducted a site visit to Perryville on October 13", 2010.During the site visit,AEA Project Manager Bryan Carey and CRW Engineer Karl Hulse met with NVP members and local fuel system maintenance staff,and toured the community's existing fuel storage and handling facilities. 3.1 PARTIES INTERESTED IN PARTICIPATION Based upon information gathered during the site visit and subsequent telephone conversations with community leaders,NVP will be the sole project participant.The LPSD will not be a participant in the project due to funding constraints. 3.2 CONTACTS Project information was provided by the entities and contacts listed in Table 1.

Conceptual Design Report 3 August 2011 4.0 EXISTING FACILITIES 4.1 EXISTING TANK FARMS There are two existing tank farms in the community;tank farm ownership is divided between NVP,local residents,and the LPSD.A summary of the existing tank farm facilities,including tank sizes,configuration and product stored,is provided in Table 2. The condition of existing tanks in the community varies considerably.Notable code deficiencies include inadequate secondary containment,improper venting,unstable foundations,lack of signage and security fence,etc.The majority of existing tanks exhibit minor to moderate corrosion. 4.1.1 Tank Farm #1 Details Tank Farm #1 is located approximately 1 mile southwest of town and 250 feet west of the Pacific Ocean (Photos 1&2).The facility consists of two vertical single-wall ASTs and sixteen horizontal,single-wall ASTs within a lined earthen containment area.The facility is owned and operated by NVP.Both vertical tanks and nine of the horizontal tanks are not currently in use. NVP utilizes four horizontal tanks at Tank Farm #1,two for diesel and two for gasoline. The diesel tanks have capacities of 10,000 and 20,000 gallons respectively and the retail gasoline tanks are both 3,000 gallons.All tanks at this facility are skid supported and resting directly on the ground within the lined earthen dikes. The remaining twelve horizontal tanks are independently owned and operated by local community members.However,due to increases in fuel prices and deteriorating tank condition,9 of these tanks go largely unused with the remaining 3 receiving intermittent use when tank owners have sufficient capital to make a bulk purchase. Bulk fuel deliveries are provided via landing a barge on the sand beach adjacent to the tank farm.The tanks are filled through two steel marine headers located within the tank farm,and 300-ft of hose provided by the barge company that is temporarily laid out from the shore to the tank farm.The marine headers include a gate valve,check valve,and camlock fitting with cap.The fill pipeline is constructed of flanged and welded steel pipe sections of various lengths (Photo 3).As a result of age,corrosion and disuse,Tank Farm #1 tanks and related components are not suitable for reuse.(see Table #2 for tank volume breakdown) Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 4 August 2011 4.1.2 Tank Farm #2 Details Tank farm #2 is located approximately 40 ft west of the school near the center of town and is owned and operated by LPSD (Photo 5).This facility includes three 7,500-gallon single-wall horizontal tank and one 500-gallon double-wall horizontal tank.The three single wall tanks are utilized for diesel bulk storage.And the double wall tank is used for fleet dispensing diesel fuel. The tanks are filled by barge via a buried steel marine header located near the beach south of the tank farm.Hose provided by the barge company is temporarily laid out across the beach.The marine header includes a gate valve,check valve,and camlock fitting with cap.The buried fill pipeline is constructed of welded steel pipe. 4.2 EXISTING TANK FARM OWNERSHIP AND CAPACITY The combined nominal gross capacity of existing bulk tanks in Perryville is approximately 59,000-gallons.The unused and privately owned tankage is not included. Table 2 lists the current users,configurations and nominal capacities for each tank. Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC.

Conceptual Design Report 6 August 2011 4.3 BULK FUEL HANDLING AND RETAIL DISPENSING PRACTICES NVP purchases diesel fuel and gasoline in bulk quantities twice per year in May & October.Pending weather,barge availability,and scheduling,a large bulk fuel barge moors in Chignik as a distribution point to multiple communities.From Chignik a lighter barge brings bulk fuel approximately 75 miles along the Alaska Peninsula to Perryville. Recent carriers used by the Corporation include Delta Western,Inc.,Alaska Coastal Freight M/V Helinka B and Crowley Marine Services. Local residents depend upon the retail sales operation for the purchase of gasoline. NVP currently has a make shift retail facility for gasoline dispensing: e Gasoline Retail Dispensing Station:The gasoline retail dispensing station is located in town adjacent to the power plant.The facility consists of a 500-gallon single wall gasoline tank plumbed to a single product dispenser housed within an adjacent plywood shed.Consumers pay for gas,and then walk to the dispenser with an NVP employee who dispenses the fuel.Gasoline sold at this facility is trucked from Tank Farm #1 using an improvised fuel truck (800-gallon steel tank strapped to a flat bed truck)owned by NVP (Photo 6).Fuel is transferred from the truck into the dispensing tank via a portable,gas-driven pump and rubber hose. 4.4 LOCAL FUEL TRANSFER CAPABILITIES NVP owns and operates the two fuel trucks in town which have capacities of 450 & 1000 gallons.The two trucks make deliveries from the tank farm to end users such as local residents,community buildings,etc.for a small fee. Fuel distribution piping in the community is limited to the tank farm and dispensing facilities discussed previously,and school-related fuel delivery systems operated by the LPSD. 4.5 REGULATORY PLANS ON FILE LPSD tanks located at Tank Farm #2,as well as the marine header and fill pipeline used to fill those tanks,are reportedly included in LPSD's Spill,Prevention,Control and Countermeasure (SPCC)plan and Coast Guard Operations Manual.The status of regulatory plans for NVPs remaining fuel facilities is unknown. 4.6 EXISTING CONTAMINATION AND CITATIONS A search of the ADEC contaminated sites database revealed a 1994 case entitled "Perryville School Heating Fuel Spil'.The database reports the status of the spill as Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 7 August 2011 'Cleanup Complete”.No known fuel spill related citations have been issued to any entity operating in Perryville. 4.7 EQUIPMENT SUITABLE FOR REUSE Existing ASTs at Tank Farm #1 are 10 to 28 years old and are not suitable for reuse. The existing single-wall,and double-wall horizontal ASTs at Tank Farm #2 are reportedly in good condition,and are expected to service the school for the remainder of their useable life.The condition of these tanks are the responsibility of LPSD,and out of the scope of this project. Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 8 August 2011 5.0 FUEL STORAGE RECOMMENDATIONS 5.1 STORAGE CAPACITY CONSIDERATIONS The following sections include a summary of historical fuel usage in the community,and identify factors such as planned infrastructure improvements,alternative energy sources,and shifts in economic outlook that could affect future fuel consumption and storage needs.As the school district will continue to use their own tankage, consumption and storage needs of the schoo!have been omitted from this report. 5.1.1 Historical Fuel Use Average annual fuel consumption in Perryville was calculated based upon information provided by NVP and several barge companies that serve the fuel delivery needs of the area.The estimated current annual consumption is presented in Table 3. Table 3 -Estimated Current Annual Fuel Consumption Fuel NVP (Heating &TotalsProductRetailSales) Gasoline 12,000 12,000 DieselFuel 64,000 64,000 Note -Retail sales include all gasoline sold to the school for transportation purposes,heating fuel sold to the City for the WTP,heating fuel for other community buildings and residences,and fuel for personal vehicle and heavy equipment operations.ULSD consumption is included in the Diesel Fuel total. 5.1.2 Planned Infrastructure Improvements Future infrastructure improvement projects can affect community fuel consumption and should be considered in the design of a new bulk fuel facility. The Bristol Bay housing authority is currently completing construction on 6 new housing units in Perryville.These units are expected to use around 500 gallons per unit and go online in fall 2011. A primary care and multi-use building was completed in Perryville in 2008.The fuel usage at this facility has been incorporated into the Current Annual Consumption. In a preliminary survey of Perryville's aging water treatment system,ANTHC has determined that a new water treatment plant will likely be constructed to meet the Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 9 August 2011 community's future needs.Design and construction funding is not yet available for this project,but it's potential fuel and electrical demands should be included in Perryville's projected future bulk storage needs.An estimated 4,000 gallons of diesel will be needed to meet the increased heating and power needs of the future water treatment plant. A Denali Commission funded barge landing is slated for construction near existing Tank Farm #1.Increases in fuel consumption due to the new landing are expected to be minimal at 500 gallons of diesel and 200 gallons of gasoline yearly. 5.1.3 Projected Community Growth Historical census data shows that the population of Perryville has risen slowly over the past 50 years at approximately 0.4%annually (from 93 in 1960 to 113 in 2010).Over the past 10 years,the growth rate has averaged about the same at 0.5%annually. For the purposes of this CDR,an average population growth of 1%was assumed, resulting in a design population of 126 in 2021.The resulting increase in heating oil demand,assuming 4 additional households are constructed to accommodate the added population,is approximately 3,000-gallons per year.Further,assuming a linear relationship between gasoline consumption and population growth,the community will require approximately 1,500-gallons of additional gasoline for motorized transportation in the design year. 5.1.4 Estimated Fuel Consumption at Design Due to the effects of community growth,Perryville's annual fuel consumption is expected to be on the order of 88,200-gallons by the year 2021.Table 4 estimates the annual fuel consumption for the design year. Table 4 -Estimated Future Retail Fuel Consumption Diesel Fuel Gasoline Current Annual Consumption 64,000 12,000 Estimated Increase 10,500 1,700 Sub-Total 74,500 13,700 Estimated Fuel Consumption in Design Year (2021):88,200 gallons Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 10 August 2011 5.1.5 Proposed Bulk Fuel Delivery Bulk fuel deliveries are typically available via lighter barge in late May and October.The proposed project will include the construction of a new triple product marine header and fill lines to facilitate transfer of diesel,gasoline and ULSD from commercial fuel barges to the proposed tank farm. 5.1.6 Method and Frequency of Local Fuel Delivery The methodology for fuel delivery to public and private facilities,with the exception of the bulk tank farm itself,will change little as a result of this project.The proposed tank farm will store diesel fuel and gasoline for NVP retail sales as well as for power generation.A dual product protected dispensing tank located near the power plant will supply fuel to a proposed new retail dispenser.Local residents will continue to purchase fuel from NVP and haul it to their homes and businesses via drums in trucks or ATV trailers.A triple-product truck fill secondary containment area will be included as part of the proposed tank farm to accommodate bulk fuel deliveries via NVPs fuel trucks. 5.1.7 Contingency Storage Needs Perryville's location on the Alaska Peninsula allows for nearly year round barge access, however,due to the economy of delivering fuel in bulk quantities,the large fuel barges come into the region twice per year,every May &October. In the fall of 2005,heavy seas and weather delayed the fuel delivery several weeks. The fuel provider had prior contracts with fishing vessels in Bristol Bay and the Bearing Sea and,after several failed attempts,Perryville was left to find an alternate method of importing fuel.Reportedly,fuel was flown in for a period of 4 months before an alternate supplier could be arranged. To account for barge delays and provide an emergency fuel reserve,it is recommended that the Village be provided with sufficient bulk fuel storage for 13- months of operation in the design year (maximum anticipated time between barge deliveries). 5.1.8 Alternative Energy Sources Diesel generators are typically considered the simplest and most reliable method of power production in rural communities.However,rising fuel costs and mounting regulatory concern over fuel spills and power plant emissions warrant a close evaluation Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 11 August 2011 of potential alternative energy sources.With proper planning,design and management, today's alternative energy technologies may be able to reduce the region's dependence upon fossil fuels in the future.Following are brief discussions of some fuel-saving technologies and the potential for their implementation in Perryville. 5.1.9 Heat Recovery Heat recovery technology,sometimes referred to as co-generation,provides a means of reclaiming energy lost to heat during the burning of fossil fuels.Co-generation systems in rural Alaska typically consist of a heat exchanger connected to the liquid cooling system of diesel generators at the community's power plant.The heat exchanger uses energy from the engine cooling system to supplement heat-reliant processes in adjacent buildings,such as pre-heating hydronic system return water to reduce boiler burn times, pre-heating raw well water to make treatment easier,etc. Perryville currently uses recovered heat from power generation to supplement diesel fired boilers at the school. 5.1.10 Wind and Hydroelectric Power Generation According to the Perryville Alaska Wind Resource Update Report,Perryville is designated as a Class 2 wind zone on a scale of 1 to 7.This designation indicates that the potential for beneficial use of wind as an energy resource in the region is marginal. In the spring of 2009 Perryville installed ten 2.5 kW wind turbines that they purchasedfromSusitnaEnergySystems.These turbines are tied into the community's power grid and help offset diesel costs.Reportedly the turbines are tied into a single phase of the power grid which has created some power quality issues.Additionally,as wind energy output tends to fluctuate rapidly over a short period of time,a genset must be kept running to meet demand. Small scale hydroelectric plants require adequate stream flow and head (elevation difference)to operate successfully,and are typically prohibited on fish bearing streams. Perryville's only potentially suitable stream is currently used as the community water supply and sufficient surplus stream flow is unlikely for the majority of the year. 5.1.11 Geothermal There are volcanic vents 20 miles NW of Perryville,and fumaroles at Kupreanoff 40 miles west.However,at this time there are no plans to pursue geothermal development for Perryville due to its small size and the prohibitive cost of transmission lines. Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 12 August 2011 5.1.12 Solar Photovoltaic Power The typical solar energy system consists of multiple arrays of photovoltaic panels situated on top of buildings,towers or other relatively high structures.The fact that sunlight intensity varies from minute to minute due to changes in cloud cover,smoke from fires,blowing dust etc.,requires that most solar-based systems have substantial battery storage.Due to the dramatic solar radiation fluctuations in northern latitudes and the practical limitations of storing and disposing of battery banks,solar systems are rarely capable of providing more than a minor amount of the total power necessary for a community.However,residential scale solar installations may be capable of meeting essential household electrical demands during the summer months. Perryville is currently designing a solar water heating system for the recently constructed multi-use building.Darkly colored piping loops will be situated on the roof or on an elevated platform allowing the sun to heat water which in turn will preheat the return side of the boiler reducing run time. 5.1.13 Alternate Combustible Fuels There are no known local sources of coal,natural gas,biomass or other alternative combustible fuels.The cost of importing such fuels is currently prohibitive. 5.1.14 Generator Efficiency Improvements Perryville's existing power generation infrastructure is aging,and in need of balancing and repairs.Upgrading the existing gensets would mean complying with current emission standards that,in some cases,reduce efficiency.No known improvements are planned at this time. 5.1.15 Fuel Type Usage NVP stocks #1 diesel for year round sales.Although #2 diesel provides more BTUs per gallon,the additional efforts associated with heating and pumping #2 fuel during the winter months is not considered acceptable.Further,residential structures are limited to #1 diesel,as the oil-fired heating stoves common in the area are not designed to burn #2 diesel. As a result of EPA regulations,NVP has seen an increased need for ULSD,and is currently supplying it to ADOT for runway maintenance and for local heavy equipment use.ULSD demand is expected to increase over the life of the tank farm.When the existing gensets are replaced,they will be required to run ULSD,which accounts for a large percentage of diesel use in Perryville.Provisions to convert diesel bulk storage to ULSD storage will need to be accommodated. Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 13 August 2011 5.2 RECOMMENDED STORAGE CAPACITY The existing and proposed fuel storage capacities for facilities within the scope of this CDR are listed in Table 5.The recommended tank farm storage capacity is based upon NVPs estimated fuel consumption at design (Section 5.1.4)and a minimum of 13- months storage.Additional details on the proposed facilities are provided in Section 6.2 and Appendix D.

Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 14 August 2011 6.1.2 Natural Hazards Perryville is located near the northern edge of the Pacific Plate along the subduction zone commonly known as the ring of fire.Design of the tank farm should follow engineering guidelines set forth in current applicable codes. The Corps of Engineers reports no known flooding within the community.The facility should be constructed at approximately the same elevation as the existing tank farm. 6.1.3 Geotechnical Conditions A geotechnical investigation of the proposed site was not completed for this CDR. Before construction,it is recommended that a qualified engineer observes the excavation of 1 or 2 test holes at the proposed tank farm location.Samples should be taken for gradation and consolidation tests.Based on local knowledge,the subsurface soils at the site are largely volcanic black sands and silts consistent with those encountered on the beaches in the area. 6.1.4 Borrow Sources,Ownership,Material Costs Sand is reportedly available from an existing borrow source owned by the Oceanside Native Corporation.Gravel can be manufactured by crushing rock from an exposed face located a half mile west of the proposed tank farm site.The quality and characteristics of these local sources is unknown.Inquiries into the cost per yard of the sand have not been answered to date. 6.1.5 Local Labor Skills A request was sent to NVP for information regarding the availability of local labor to assist with construction of the proposed project.Reportedly there are fourteen laborers with (6)truck drivers,(7)operators,and (2)mechanics that could be available to work on the project.No certified welders or electricians were noted. 6.1.6 Local Equipment Local community entities own several pieces of heavy equipment which may be available for the project.The type and condition of each piece is listed in Table 6.

A site control opinion prepared by Rick Elliot Land Consultant is included in Appendix B. 6.1.9 Electrical Tie-in The proposed tank farm site is not currently serviced by the electric utility and the closest existing buried power is almost a mile to the northeast.Extending the buried power grid to service the tank farm would cost a sizeable portion of the projects Perryville Bulk Fuel Upgrades Conceptual Design Report 16 CRW Engineering Group,LLC. August 2011 construction cost along with adding some potential site control issues in crossing airport property. An alternative approach would be to provide an onsite generator with a pre-engineered enclosure.The onsite genset would run only during facility operation to power pumps, lights,and other electronic equipment. 6.2 PROPOSED IMPROVEMENTS 6.2.1 Scope of Work The proposed project scope of work includes the following upgrades: e Anew bulk fuel tank farm with five horizontal single wall,skid mounted ASTs : o (8)28,000-gallon #1 diesel o (1)3,000-gallon ULSD o (1)13,500-gallon gasoline e The proposed tanks will be placed within a new earthen dike containment area constructed of local sand. e A truck-filled,protected dispensing tank with dual product retail dispenser (gasoline and #1)adjacent to the power plant e A new,triple product barge header with three 60-ft long,3-inch diameter, schedule 80 steel above grade pipelines installed to fill the facility. e Anew truck fill secondary containment area at the tank farm. e New electrical controls as required. e Closure of all existing tanks replaced by the project. e EPA-required spill contingency equipment and related regulatory documents. 6.2.2 Non-Scope Items Non-scope items include system components that may be relevant to the project,but do not fall within the bounds of Denali Commission funding criteria.These components might have been discussed during the CDR phase of the project,and AEA might assist in identifying and pursuing alternative funding sources for them,but they will not be funded under this project.Typical non-scope items that are relevant to the Perryville project include: e Anew fuel delivery vehicle, e Site remediation, Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 17 August 2011 e Disposal of closed tanks. e See Section 1.0 Program Overview for additional information on non-scope project components. 7.0 PROPOSED OPERATING SCENARIO AND SPILL RESPONSE The NVP,the Project Grantee,will act as the Primary Operator (PO)of the facility.NVP will own all project-related elements of the facility,and will oversee operation and maintenance (O&M)of the facility,as well as training,testing,and other responsibilities as outlined in the business operating plan (BOP).NVP will maintain and contribute to O&M and renewal and replacement accounts in accordance with the BOP. As currently envisioned,the tanks in the proposed tank farm will be filled twice annually, typically in the May &October,via the proposed dual product marine header and fill lines.The fuel barge's on-board pumps will be used to transfer the fuel to the bulk tanks. Proposed new facilities will be subject to applicable EPA and USCG regulations.Since the project includes marine headers and fill lines,an Operations Manual and a Letter of Intent will need to be prepared and submitted to the USCG.An Oil Spill Facility Response Plan will need to be prepared and submitted to both the USCG and the EPA. The facility will also require preparation of a SPCC plan.Spill response gear,including sorbent pads,protective safety gear,a fuel transfer pump,etc.will need to be purchased and stored on site.Due to the project's close proximity to the coastline,a 5,000-gallon spill contingency storage tank,or a collapsible,commercial-type contingency basin(s),will also be required on site. 8.0 PERMITTING Required state and federal permits should be identified early in the design phase by distributing a scoping letter to interested agencies.The following permit requirements are anticipated for this project: e Preparation of an Environmental Assessment (EA)in accordance with the AEA procedures and requirements of the National Environmental Policy Act (NEPA) (see Section 8.1) e Review by the State Historic Preservation Officer e State Fire Marshal Plan Approval e SPCC Plan preparation Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 18 August 2011 8.1 ENVIRONMENTAL ISSUES In accordance with the NEPA an Environmental Assessment must be completed prior to construction of the project.The EA format should be based on the guidance documents provided in the AEA Reference Manual.The EA process should include the development and distribution of a project-scoping letter to all interested agencies. Responses from the agencies should be attached to the EA checklist as justification for a Finding of No Significant Impact (FONSI)for the project.AEA will act as the lead agency for FONSI determination. 8.2 SITE CONTAMINATION Due to the age of the existing bulk tank facilities and the lack of any positive overfill prevention devices,some contamination may exist in the vicinity of the existing tank farms and barge headers.The extent of any contamination is unknown. The proposed tank farm will be constructed above grade,in an undeveloped area with no known contamination. 9.0 CONSTRUCTION PLAN 9.1 ADMINISTRATION The AEA has a history of administering Bulk Fuel Upgrade Projects on a "modified" force-account basis.Force-account construction involves the owner or grantee acting as the employer and utilizing primarily local labor.This method tends to achieve a higher percentage of local hire and is strongly supported by many communities and funding agencies. The technical nature of a tank farm project requires a limited number of workers with specific experience and expertise to be brought in for the project when not available locally.An experienced Construction Manager will be required to recruit the necessary skilled labor,coordinate the construction team,and oversee procurement and project logistics.All work should be supervised and managed by a superintendent with extensive experience in the construction of rural fuel facilities.The Design Engineer should provide quality control through communication with the construction manager , submittal review and periodic on-site inspections 9.2 CODES AND REGULATIONS The proposed bulk fuel upgrades should be designed and constructed in accordance with the requirements of the following codes: Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 19 August 2011 e Current International Fire Code (IFC),including State of Alaska Amendments e Current National Electrical Code (NEC) e 40 Code of Federal Regulations (CFR),Part 112.1-12,EPA Spill Prevention Requirements,including pending Revisions The design should also incorporate appropriate industry standards such as those recognized by the National Fire Protection Association (NFPA)and American Petroleum Institute (API),as well as proven methods and materials that have been used successfully on other rural bulk fuel facilities in similar locations and climates. 9.3 CLOSURE OF EXISTING TANKS Existing tanks replaced or taken out of service as a result of the project will be permanently closed in accordance with EPA requirements.A tank is considered permanently closed by the EPA after: e The liquid and sludge is removed from each tank, e All connecting lines are disconnected and blanked-off, e All valves (excluding those used for ventilation)are closed and locked,and e Signs are posted on each tank stating that the tank is permanently closed and noting the date of closure. In addition to the EPA requirements,the AEA has typically requested that the closed tanks be rendered non-useable by cutting holes in the tank shells.Existing tanks are typically closed after completion of the new facility,allowing fuel from the old tanks to be transferred to the new facility. 9.4 USE OF LOCAL LABOR The modified force account construction approach previously described in Section 9.1 will provide employment opportunities to the local labor force.The AEA Construction Manager will import skilled craftsmen,with appropriate certifications,to perform specialty work only (such as pipe welding and electrical panel installation).Other positions including laborers,equipment operators,etc.will be filled by locals whenever possible. 9.5 USE OF LOCAL EQUIPMENT NVP has indicated that its equipment is available for use for the project (Table 6).If the Construction Manager plans to use this equipment,a qualified mechanic should travel to Perryville and go through the equipment to ensure that it is in proper operating condition prior to construction.Maintenance,repair and fuel used for the project will be Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC. Conceptual Design Report 20 August 2011 paid as part of the user agreement.Any supplemental equipment should be leased from a reputable rental agency and mobilized to the site by barge. 9.6 CONSTRUCTION SCHEDULE A preliminary construction schedule is provided as Table 7.Subject to funding,the schedule calls for design and permitting to occur during the summer &fall of 2011. Construction is tentatively scheduled to begin in the spring of 2012. Perryville Bulk Fuel Upgrades CRW Engineering Group,LLC.
