A site investigation was conducted on September 17,1999,by Gerry Brown (Dames &Moore engineer),Bruce Teideman and Karl Reiche (AEA/REG and Rampart representative).The Village representative,Ms.Denise Newman,was contacted during the site visit to gather information on the condition of the existing facilities,determine fuel requirements,and provide input on preferred locations for a future fuel farm.A Site Visit Meeting Summary was submitted to AEA/REG on December 27,1999,and is attached as Appendix A.Each existing fuel farm was documented by a visual inspection and photographed for future reference.An updated AEA/REG Bulk Fuel Community Database is attached as Appendix B. 2.0 SITE DESCRIPTION AND EXISTING FUEL STORAGE FACILITIES 2.1 SITE DESCRIPTION Rampart Village is located on a north-facing slope on the south bank of the Yukon River, approximately 75 miles upstream from its junction with the Tanana River and 100 air miles northwest of Fairbanks (Figure Cl).The climate is characterized by extreme daily and seasonal temperature changes.Wintertime temperatures can drop as low as -70 degrees Fahrenheit (°F), while summer temperatures reach as high as 90°F.Precipitation is low,averaging 6.5 inches SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE l D&M Jos No.37203-017-220 annually.Most of the precipitation occurs from June through August.The prevailing winds come from the northeast during the winter and from the west or southwest during the summer. The dominant soils in the area are water-deposited silts and fine sands underlain by continuous permafrost.In some areas,the sediments are covered by a windblown layer of silty loam ranging in depth from a few inches to several feet. There are approximately 45 single-family dwellings in Rampart.Other structures include a school,a diesel-generated power plant,a washeteria,a clinic,a community hall,a village corporation store (Trading Post),and a teen center.The school is currently closed due to low attendance.However,the Rampart Village Traditional Council (Village Council)expects the closure to be a temporary situation.Village Power is reported to be provided by the Weisner Trading Company. Rampart,located on the south bank of the Yukon River,is subject to flooding and bank erosion. An ice jam in 1963 caused the highest flood level in recent memory.The flood level was approximately 8 feet above the riverbank and approximately up to the elevation of Second Avenue in the vicinity of the Trading Post.River ice can also pose a threat to buildings along the riverbank.The gravel airstrip and maintenance building,located approximately 0.75 miles northeast of Rampart,are much lower in elevation than the Village,and are especially prone to flooding (Appendix C).Second Avenue extends to the airport and generally has a slope comparable to the riverbank until an abrupt grade change at the airport. 2.2 EXISTING FUEL STORAGE FACILITIES Four bulk fuel facilities,two intermediate and two day tanks were identified and investigated at Rampart.These facilities are owned and operated by: e Tank Farm 1 -Yukon Flats School District,Rampart School (School) e Tank Farm 2 -Baan O Yeel Kon Corporation (Village Corporation) e Tank Farm 3 -Trading Post Gasoline Dispensary e Tank Farm 4-ADOT&PF,Airport tanks e Intermediate Tanks -Washeteria and Clinic e Day Tanks -Power plant and School The following sections summarize the results of the site investigation,and provide a description and condition of each tank farm,intermediate and day tanks,and related facilities that were evaluated as part of this project.The layout of the community and the location of each tank are SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 2 D&M JoB No,37203-017-220 shown on Figure Cl.Photos taken during the site visit are referenced throughout this section and are included at the back of the report. 2.2.1 Tank Farm I -School Although the School and Village Council have co-located their tanks into a single facility,the tanks and piping are considered separate fuel storage facilities identified as Tank Farm 1 and Tank Farm 2,respectively.However,the secondary containment and site characteristics are the same for both tank farms and are discussed in this section. Tank Farm 1 consists of five vertical,steel tanks located on Fourth Avenue,just south of the Old Bureau of Indian Affairs (BIA)School,approximately 600 feet from the river.The BIA School likely has a day tank inside the mechanical room,but this could not be verified because access to the BIA School could not be obtained during the site visit.Tank Farm 1 stores diesel fuel for water and space heating at the BIA School.The tank farm lacks two secondary containment berms,the liner,chainlink security fence,and lighting (Photo 1).Because the tank farm is located on a side slope possibly underlain with permafrost,considerable settlement has occurred causing tanks to list (Photo 2). Currently,fuel is delivered to the airport by Everts Fuel Service and is transferred to Tank Farm 1 using either a tanker trailer or a tanker truck,both owned by the village but in disrepair. Historically,the tank farm has also received fuel via barge,with the transfer line strung from the barge landing area to the tank farm (Figure C2).Several fuel releases have reportedly occurred over the years.The total capacity of Tank Farm 1 is 29,935 gallons,based on a 90 percent (%) capacity. 2.2.1.1 Tanks Tank Farm 1 consists of five tanks,two are newer vertical steel tanks (Tanks 1-1 and 1-2)and three are old BIA-type vertical steel tanks (Tanks 1-3,1-4,and 1-5).The tanks are supported bytwolayersofcross-lain,2-by 12-inch timbers.Tanks 1-1 and 1-2 (8,965 and 8,165 gallons, respectively)are each equipped with a 3-inch threaded fill penetration,a 2-inch threaded discharge penetration,and a 1-inch water draw along the bottom circumference of the tanks.The top of each tank is equipped with a 24-inch manhole,4-inch normal vent,two 1-inch threaded pipes with caps,and a tape level gage;the level gage on Tank 1-1 was broken (Photo 3). Although these tanks lack ladders,emergency vents,and overfill limiting or warning devices, they appear to be good structural condition with minimal bare paint or corrosion. SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 3 ; D&M JoB No.37203-017-220 Tanks 1-3,1-4,and 1-5 (4,010,3,010,and 5,785 gallons,respectively)are similar tanks,but apparently much older and smaller than Tanks 1-1 and 1-2.Each of these tanks is equipped with bottom-mounted 1-inch threaded water draws and 3-inch threaded penetration used for both filling and withdrawal.The top of each tank is equipped with a 4-inch normal vent,two 1-inch threaded pipes with caps,and a tape level gage.In addition,Tank 1-5 is equipped with a 24-inch Tanks,1-3,1-4,and 1-5 lack ladders,code compliant emergency vents,and fill limiting devices.These three tanks appear to be in poor structural condition and have noticeable manhole. pitting and corrosion (Photo 2).A tank summary is provided in Table 1.

The tanks appear to be filled by connecting a rubber fill line,or barge offload line,to a 3-inch branch from the manifold that terminates with a 3-inch gate that is missing a handle (Photo 4). The discharge manifold consists of 2-inch steel pipe with victaulic fittings.On Tanks 1-1 and 1- 2,the manifold is connected to the 2-inch threaded penetrations provided opposite the 3-inch threaded penetrations.On Tanks 1-3,1-4,and 1-5,a single penetration is used for both filling and discharge.The victaulic discharge manifold was observed to branch in several directions below grade (Photo 4).The endpoints of these lines could not be verified but are believed to run to the BIA School,the newer School,and to one of several buildings associated with the School. Throughout the tank farm,several actively leaking fittings were observed with large areas of stained soil (Photo 5). Two recent fuel releases were described during the site visit.One involved a release that migrated to a drainage channel and collected in a pond where it was partially recovered (Photo 6).A second release occurred during the transfer of fuel to Tank Farm 1,and required JULY 2000 D&M Jos No.37203-017-220 SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT RAMPART VILLAGE BULK FUEL UPGRADE 4 excavation and stockpiling of fuel contaminated soil from the roadway (Photo 1).The community water well is located approximately 200 feet downgradient from this release. 2.2.2 Tank Farm 2 -Village Council Tank Farm 2 is owned by the Village Council and is located within the same containment area as Tank Farm 1.Tank Farm2 is used to store diesel fuel for generating electricity at the Village- owned power plant,and for water and space heating at the washeteria and clinic.The general characteristics of Tank Farm 2 are consistent with those described for Tank Farm 1.Both Tank Farms 1 and 2 were observed to have several UFC deficiencies.The primary deficiencies are related to secondary containment,emergency venting,and dispensing. 2.2.2.1 Tanks Tank Farm 2 consists of a single,18,520-gallon,single-walled,steel,horizontal,skid-mounted tank (Tank 2-1).The tank is supported by a unidirectional layer of lumber of various dimensions lain under the steel skids of the tank (Photo 7).Two 2-inch threaded penetrations were observed - on top of the tank.One was fitted with two 90-degree elbows for ventilation,while the other was equipped with a Camloc fitting apparently used for filling the tank.Tank 2-1 lacks a normal vent,emergency vent,ladder,manhole,and an overfill limiting or warning device.Structurally, the tank appears to be in good condition with little evidence of corrosion.An existing tank summary is provided in Table 2.

The distribution pipeline to the dispenser and BIA School reduces to a 1%-inch threaded pipe near the diesel dispenser;a Gasboy Model 1820 (Photo 9).This dispenser is used to transfer fuel to Village equipment and to facilitate transport of fuel to the washeteria and clinic intermediate tanks.The distribution pipeline to the BIA School went below grade at the edge of the tank farm. 2.2.3 Tank Farm 3 -Trading Post The Trading Post owns a single horizontal tank,Tank 3-1,that is currently located adjacent to Second Avenue approximately 200 feet from the Yukon River (Figure C2,Photo 10).The Trading Post originally acquired this tank to be used as a retail gasoline dispensary.At the time of the site visit,the tank was empty and had not yet been installed as a fuel dispensing tank. Currently,gasoline is being sold at a local resident's home,at no profit,as a courtesy to Rampart residents.Otherwise,residents travel by boat,or snowmachine in the winter,to the bridge crossing the Yukon River to purchase their personal fuel supply. 2.2.3.1 Tank Tank 3-1 is a 2,685-gallon,single-walled,horizontal steel tank with no saddles or skids,The tank has three 2-inch threaded penetrations,two located on top of the tank and one located at the bottom,which was fitted with a gate valve.The tank is not equipped with any vents or other appurtenances.Tank Farm 3-1 appears to have decent paint and minimal rust,but a dent on one end and on the rim appeared to have a leak.An existing tank summary is provided in Table 3.

JULY 2000SITEINVESTIGATIONANDPRELIMINARYDESIGNREPORT-DRAFT RAMPART VILLAGE BULK FUEL UPGRADE 6 D&M JoB No.37203-017-220 2.2.4 Tank Farm 4 ADOT&PF Airport Tanks Tank Farm 4 is located at the airstrip maintenance building approximately 400 feet from the Yukon River and is owned and operated by ADOT&PF.The tank farm provides heating and aviation fuel for the airfield.Tank Farm 4 consists of three tanks with a total storage capacity of 3,075 gallons,based on a 90%capacity.This tank farm is outside the scope of this project and, therefore,will not be included in the proposed upgraded tank farm and will not be considered for rehabilitation or discussed in the remainder of this report. 2.2.4.1 Tanks Tank Farm 4 consists of three tanks,one that stores heating oil for ADOT&PF shop facility (Tank 4-1),and two tanks that store aviation fuel (Avgas)for unknown aircraft (Tanks 4-2 and 4- 3).Tank 4-1 is a code-compliant Ace Dike Tank,supported by 4-by 4-inch treated timbers,and in good structural condition with good paint and minimal corrosion (Photo 11).Tanks 4-2 and 4- 3 are used for dispensing Avgas (Photo 12).The smaller tank is equipped with a Fill-rite Series 700B dispensing pump,and a 1%-inch normal vent.However,the tank does not have an emergency vent and is supported by wedges inserted between the bottom of the tank and the ground on which it rests.Tank 4-3 appears to be an overflow tank for Tank 4-2.This tank is equipped with two 2-inch threaded,top penetrations and a 1-inch,bottom-mounted water draw. Both Tanks 4-2 and 4-3 are in poor structural condition,with dents and seeps,and have numerous areas of bare metal with corrosion.An existing tank summary is provided in Table 4.

There was no other piping observed at Tank Farm 4. SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 7 D&M Jos No.37203-017-220 2.3 INTERMEDIATE AND DAY TANKS 2.3.1 Rampart Washeteria and Clinic Intermediate Tanks The Rampart washeteria and clinic intermediate tanks are located on the south side of the new clinic along Fourth Avenue.A new drinking water well is located in front of the washeteria, approximately 130 feet northwest of the intermediate tanks.Each tank has a 500-gallon capacity,but the washeteria tank is of double-walled construction while the clinic is of single- wall construction.Fuel is transferred to the top fill ports on the intermediate tanks using a Koshin LTD Model SHE-50X pump rated at 158 gallons per minute (Photo 13). The intermediate tank that supplies the Clinic is supported on an elevated wooden platform, while the washeteria intermediate tank has two rows of timbers wedged at the bottom to prevent rolling.The clinic intermediate tank is equipped with three 2-inch and one 4-inch threaded penetration on top of the tank.One of the 2-inch penetrations is fitted with a capped segment of pipe and another has a locking cap used as the fill port.The remaining penetrations are plugged (Photo 14).The clinic tank lacks normal and emergency vents,as well as an overfill limiting or warning device.The issue line consists of a %-inch pipe,with a gate valve and fuel filter,fitted into a 2-inch threaded tank penetration at the bottom of the tank.The line from the filter to the oil burning monitor inside the clinic is 4-inch copper tubing. The washeteria intermediate tank is equipped with five 4-inch and four 2-inch threaded fittings on top of the tank.A level gage and normal vent is installed in two of the 2-inch penetrations and a top-mounted overfill container is installed on one of the 4-inch penetrations (Photo 15). Although this double-walled tank was observed to have a normal vent installed in the interstitial space,it should also have an emergency vent on the interstitial space,as well as normal and emergency vents on the storage compartment.The issue line from the washeteria tank consists of a 2-inch,threaded steel pipe fitted with a flex connection.The issue line is secured using channel strut along the length of the run to the washeteria (Photo 16) The overfill container on the washeteria tank does not appear to be effective based on observed soil stains and visible overfill stains on the tank around one of the remaining plugged penetrations (Photo 13).Soil contamination was also observed below the shut-off valve on the clinic intermediate tank. 2.3.2 Power Plant Day Tank The Village power plant is located west of the existing School and Village Council tank farms. Fuel is automatically transferred from Tank 2-1 using a transfer pump,Dayton Model 4K928 Srre INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 8 D&M Jos No.37203-017-220 with 1/3 horsepower motor,mounted on top of a 75-gallon Pryco day tank located inside the power plant building (Photo 17).Inline filters are installed on the incoming supply line from Tank 2-1 to protect the generators and solenoid valves on the day tank. 2.3.3 Village Tanker Trailer and Trucks The village owns two tanker trucks and one tanker trailer.One yellow tanker truck (Photo 1)is reported to be out of commission and the other truck's engine was in disrepair during the site visit (Photo 12).The yellow truck is assumed to be beyond repair.The tanker truck needing engine repairs was recently acquired from a local mining company and appeared to have four separate tank compartments.The tank on the truck appeared to be in good condition and has an estimated storage capacity of 2,500 gallons (Photo 18).Reportedly,efforts to repair this tanker truck have been thwarted due to difficulties in locating a new manifold,required for the repair. For this reason,the Village is investigating the possibility of obtaining a surplus tanker truck from the DOD. The tanker trailer is currently used to transfer fuel from the airport to Tank Farms 1 and 2.A local contractor is hired to hook-up a piece of his construction equipment to the broken tongue on the trailer.The practice does not appear to be safe.The tanker trailer was observed to have several welds that have been damaged and are apparently leaking (Photo 19).The method of attaching the tanker trailer to the tanker truck appeared to require a non-conventional connection which is likely to be unsafe. 2.4 REUSE OF EXISTING FACILITIES Based on the condition of the existing tanks,tanker trucks,and tanker trailer,limited reuse is planned in the bulk fuel upgrade.Tanks 1-1,1-2 and 2-1 appear to be reusable in the proposed upgraded tank farm.The tanker truck that is currently in need of engine repairs and the tanker trailer appear to be reusable,with structural and mechanical repairs.The primary transport vehicle should be the truck,with the trailer used as a backup should the truck breakdown.Both of these fuel transport vehicles should be reclaimed during the tank farm upgrade,either as part of the upgrade or by the Village through separate funding.Final determination of tank reuse will be based upon tank field-testing results. All piping,above and below grade,should be removed or abandoned in place.Piping leading to and from intermediate and day tanks should be upgraded to schedule 80,welded,steel pipe with flanged fittings.Cathodic protection and secondary containment will be included in the below grade segments of the distribution piping. SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT .JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 9 D&M Jos No.37203-017-220 Intermediate tanks were recently installed during the construction of the new clinic and washeteria.Although these tanks are in like-new condition,it does not appear to be feasible to have two separate intermediate tanks for the clinic and washeteria.The existing 500-gallon, double-walled washeteria tank,and the 500-gallon clinic tank will be replaced with a new 2,000- gallon,double-walled intermediate tank which will be shared between these facilities.Ultimate selection of an intermediate tank will depend on the final site selection,which will be discussed later. 3.0 CURRENT AND FUTURE FUEL STORAGE AND USAGE Fuel use and storage capacity considerations were separated into the following: e School -Tank Farm 1 e Village Council -Tank Farm 2 (power plant,washeteria,and clinic) 3.1 CURRENT FUEL STORAGE AND USAGE The school is estimated to consume approximately 18,000 gallons of diesel fuel annually for heating.The Village Council is estimated to consume approximately 20,000 gallons of diesel fuel and 5,000 gallons of gasoline annually.For the total diesel fuel consumption,the Village power plant consumes approximately 16,000 gallons for power generation,the washeteria and clinic consume approximately 2,500 gallons for water and space heating,1,000 gallons for Village equipment,and the remainder (500 gallons)is dispensed to the community for use in oil- burning monitors.Although 92%of the community currently uses wood as their primary heat source,the popularity of oil heat is growing.Gasoline is used in various vehicles,small engine equipment,four-wheelers,boats,and snow machines owned by Village residents.The total gasoline consumption for the Village is estimated to be approximately 4,000 to 5,000 gallons which is dispensed at the Newman home as a non-profit courtesy to village residents.Tanana residents also come to Rampart to take advantage of this gasoline courtesy and it is thought that they would continue to buy fuel at the new tank farm. Therefore,the total annual estimated fuel consumption for the Village (Village Council and school)is approximately 38,000 gallons of heating fuel and 5,000 gallons of regular unleaded gasoline,for a combined total petroleum product consumption of 43,000 gallons (Table 5).

The current population of Rampart is reported to be 66 people.Assuming a 20-year design life for the proposed facility and an annual population growth of 5 people per year,the 2020 population may be in excess of 166 people.This population growth may seem high,but could be realized if several proposed projects are completed.A rehabilitation of the existing runway is funded and should be constructed in the near future.A study to upgrade the Village water and sewer system is underway and may lead to an increase in sanitation infrastructure.The community is actively constructing new homes funded by the U.S.Department of Health and Urban Development (HUD)each summer.Most importantly,a 14-mile road project is planned to connect Rampart to Eureka,on the Elliott Highway,for the year 2006.With access to the Elliott Highway,the Yukon River,and air traffic,and improved sanitation and housing,Rampart could be well situated for economic and population growth in the future.These factors will impact fuel use in Rampart. Given the potential impacts to commerce related to an increased transportation infrastructure, Rampart's future fuel consumption will not likely be directly proportional to population growth. This premise is based on an expected increase in automobiles and subsequent retail gasoline sales if the road from Eureka is constructed.Based on a review of consumption for other Villages with current populations similar to Rampart's projected population,the following fuel consumption estimates are expected by 2020.With a population of 166 people,Rampart can expect annual diesel use to increase to 30,000 gallons for power generation,3,000 gallons for space and water heating in Village facilities,3,000 gallons for vehicle use,and 3,000 gallons for home heating.The annual diesel consumption for the school is expected to increase to 24,000 gallons.Gasoline consumption is difficult to estimate,but could be as high as 20,000 gallons SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUBL UPGRADE 11 D&M JoB No.37203-017-220 annually.This increase in fuel consumption could relate to approximately 83,000 gallons of total petroleum consumption by 2020 (Table 5). 4.0 PROPOSED BULK FUEL FACILITY There seems to be adequate need for a bulk fuel tank farm upgrade at Rampart,Alaska.The existing tank farms each have UFC violations,posing health and safety concerns to Village residents.The distribution pipelines from Tank Farms 1 and 2 to the surrounding facilities consist of below grade victaulic piping that is likely leaking;active leaks were observed in aboveground portions of the piping.The victaulic manifold piping that was observed to be leaking at Tank Farms 1 and 2 does not appear to be adequately contained.The secondary containment area does not have an impermeable liner and is not bermed to prevent overland flow:Fuel transfer operations also appeared to be problematic,in that several releases have reportedly occurred in the past.Construction of a new tank farm with adequate secondary containment and necessary equipment to conduct safe fuel transfers should provide a higher level of safety to residents from fuel-related activities.The Village Council indicated a need for a propane storage facility within the vicinity of the new tank farm;however,this was not included in the scope for this project. 4.1 CO-LOCATED TANK FARM The scope of the project includes relocation of Tank Farms 1 and 2 and providing a more effective means of transferring,distributing,and dispensing fuel (Figures C2 and C3). Historically,Rampart received fuel shipments via barge.Recently,fuel shipments have also been received via aircraft.Dames &Moore proposes to incorporate both modes of delivery into the design of the proposed facility.The proposed facility will be equipped with a dual-product barge offloading header and pipeline for barge shipments,as well as a dual-product tanker truck on/offloading rack for delivery of airport shipments and truck distribution of heating fuel to residents.Fuel dispensing will be conducted exclusively at the proposed tank farm facility and operated by the Village Council.Distribution of fuel to the washeteria,clinic,and school will either be via pipeline or tanker truck,depending on the ultimate site selection. After the new airport is constructed,fuel will be transported to the co-located facility using a dual-compartment tanker truck that the Village Council is planning to purchase in the future.A double-walled,dual-product holding tank and loading rack will need to be installed at the new airport sometime in the future to provide the Village with a safe and effective means of transferring fuel. SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 12 D&M JoB No.37203-017-220 4.2 SITE SELECTION During the site visit,the Village Council was asked to identify sites in the community that would be preferred for construction of the proposed tank farm facility.Three sites were identified:Site 1,located at the intersection of Fourth and Fifth Avenue near the existing power plant;Site 2, located west of the School lagoon on previously undeveloped property,and Site 3,located near the airport along the banks of the Yukon River and adjacent to Second Avenue (Appendix A). The Village indicated that their preferred site for constructing a tank farm is Site 1.However, because construction of a tank farm at this site may not be feasible,Site 1 is presented as the proposed site and Site 3 presented as an alternative site in this report.Site 2 was withdrawn from consideration due to suspected poor soils and limited access to the site.An evaluation of advantages and disadvantages of each site is included in the Meeting Summary (Appendix A) 4.2.1 Proposed Site Description The proposed site for constructing a tank farm is located on Block 11,Lots 2 and 3 of the USS 5049 survey (Figure Cl).A property profile on the site indicates that the Village owns Lot 3, while the VSW could hold a lien on Lot 2 (Appendix D).The combined lots form an irregular shaped area comprised of approximately 0.7 acres.The site slopes moderately toward the river and is vegetated with trees,grass,and shrubs (Photos 20,21,and 22).The size and slope of the property restricts possible tank farm dimensions.Review of previous geotechnical reports indicated presence of permafrost in the general vicinity.Based on these reports and observed vegetative cover,poor soil conditions or permafrost is presumed at this site.Property issues,site restrictions,and poor soil conditions could be the bone of contention for the proposed site. 4.2.2 Alternative Site Description The alternative site for the proposed facility is located approximately 1,400 feet from the airport, on Block 2,Lot 1 of the USS 5049 survey.This site is along the bank of the Yukon River adjacent to the right of way of Second Avenue (Figure C1).According to Ms.Newman,the Doyon Native Corporation currently owns the property,but owes the village dedication land; therefore,it may be possible to obtain a portion of Lot 1 for the proposed project.The Village Council is currently investigating the possibility of obtaining this property. The site is heavily vegetated with trees,grass,and shrubs,and is at approximately the same elevation as Second Avenue,with no noticeable grade.This alternative site appears to be located within the flood zone of the Yukon River.This assertion is based upon reference to Second Avenue,which is known to be slightly within the floodplain at the Trading Post,approximately 2,800 feet away,and appears to follow the same grade as the riverbank (Appendix C). SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 13 D&M JoB No.37203-017-220 4.3 PROPOSED FACILITY DESCRIPTION The School and Village Council will use a combination of refurbished and new bulk tanks for maximizing their storage capacity on the proposed site.Furthermore,to maximize the space available,the School and Village Council tanks are not proposed to be separated by an intermediate dike within the proposed tank farm (Figures C2 and C3).The tank farm will be equipped with two options for fuel delivery:barge and truck haul from the airport. Two pipelines will be used to transfer fuel to the tank farm from a new,dual-product header located at the existing barge landing area (Figure C2).Gasoline and diesel delivered at the airport will be transferred to the proposal bulk tank farm using the tanker truck.Therefore,the tank farm will also be equipped with a tanker truck on/offloading rack for transferring fuel to and from the tanker truck.In order to provide access to the on/offloading rack,the existing driveway will be raised (Figure C4).The tanker truck will be provided with different connections for diesel and gasoline to prevent cross-contamination of product.The tanker truck may also be used to deliver diesel to residential heating fuel day tanks,or to facilitate a transfer between the School and Village Council bulk fuel tanks.However,the tanker truck should not be used to dispense gasoline.Dispensing of gasoline should only be conducted at the dual-product dispensing station that is constructed with a turn-in fueling area (Figure C2). 4.3.1 Secondary Containment Due to lack of available space associated with site restrictions,the tank farm containment area will be constructed with 1:1 slopes on the berms,using stacked geogrid and earthen berm design (Figure C4).The containment cell will be constructed with an impermeable liner within the fill section (Figures C4 and C5).Beneath the liner,a 4-inch layer of rigid foam insulation will be installed to retard degradation of permafrost.The bermed cell will be graded toward drainage sumps to allow for removal of storm water.The perimeter of the tank farm will be enclosedwithina6-foot,chainlink,security fence,with three gate entrances.A 3,000-gallon emergency spill response tank will be provided outside the bulk tank farm to comply with EPA and Coast Guard facility response plan requirements.The Village Council will maintain approximately 36,000 gallons of diesel storage,9,000-gallons of gasoline storage,and a 4,000-gallon dual- product dispensing tank,while the School will maintain approximately 26,100 gallons of diesel storage at 90%nominal tank capacity. A truck on/offloading rack will be located in an adjacent cell to the northeast of the tank farm (Figures C2 and C3).The on/offloading rack will be able to dispense diesel using a high-rate dispensing pump located on the diesel side of the dual-product,dispensing tank.The on/offloading rack will be contained within a lined,earthen bermed area.The bermed area will SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 14 D&M JoB No.37203-017-220 be graded to permit back-in access and will also be provided with a drainage sump to allow removal of storm water (Figures C4 and C5).The on/offloading rack cell will be provided with a 6-foot,chainlink,security fence and have a vehicle entry gate accessible from the driveway.The driveway will have to be raised in order to provide access to the on/offloading rack,while meeting UFC setback requirements. 4.3.2 Tanks The Village Council will maintain:one refurbished 20,000-gallon,horizontal,single-walled, skid-mounted steel bulk fuel storage tank and two new 10,000-gallon,vertical,single-walled, steel tanks for diesel storage (Figure C7);one new 10,000-gallon vertical,single-walled,steel tank for gasoline;one refurbished 3,000-gallon vertical,single-walled,steel tank designated as an emergency spill response tank;one new 4,000-gallon,dual-product,single-walled,horizontal, skid-mounted steel dispensing tank (2,000 gallons gasoline and 2,000 gallons diesel,Figure C6); -and associated piping (Figure C3).The School will maintain two refurbished vertical,single- walled,steel diesel fuel bulk storage tanks (9,950 and 9,050 gallons,respectively);one new 10,000-gallon,vertical,single-walled,steel diesel fuel bulk storage tank (Figure C7);and associated piping.Each tank will be equipped with appurtenances as required by applicable codes.The proposed facility will provide the Village with approximately 73,100 gallons of fuel storage at 90%nominal tank capacity. To facilitate offloading from incoming aircraft,a 12,000-gallon,dual-product,holding tank and associated truck offloading rack will be located at the new airport apron (Figure C1).The facility will include an aircraft offloading header and pipeline,overfill limiting devices,transfer pumps,gravel tank pad,back-in offloading rack,drain sumps,security fence,and lighting. Construction of the offloading facility is contingent upon construction of a new apron by ADOTE&PF. The washeteria and clinic intermediate tanks will be replaced with one 2,000-gallon,horizontal, double-walled intermediate tank equipped with a connection to allow for safe and efficient fuel transfer from the tanker truck.Similarly,the School will be provided with a 2,000-gallon, horizontal,double-walled intermediate tank.Because the power plant is adjacent to the proposed tank farm,it will be provided with a pipeline connection from the proposed tank farm to the existing day tank. 4.3.3 Piping and Appurtenances for Dispensing and Receiving Product There is suspected contamination from buried pipelines that lead from the existing tank farm across the road to the School and washeteria.Furthermore,a new drinking water well was SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT .JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 15 D&M Jos No.37203-017-220 recently installed down gradient from the existing tank farms and the proposed intermediate tank locations.For these reasons,Dames &Moore does not recommend constructing distribution pipelines to these intermediate tank locations.Instead,the new intermediate tanks will be filled using the tanker truck,sized to minimize filling frequency,and equipped with proper connections and overfill limiting devices to minimize the risk of spills. The proposed tank farm will receive diesel and gasoline by two means:a dual-product barge offloading header and pipeline from the existing barge landing area and a permanent offloading rack located adjacent to the proposed tank farm.The barge offloading pipeline will consist of two dedicated (one for diesel and one for gasoline),3-inch,schedule 80,welded steel pipelines with flange connections. A back-in,dual-product on/offloading rack will be constructed in a cell separate from the main tank farm cell (Figures C2 and C3).Two offload lines,gasoline and diesel,will be used to transfer fuel from the tanker truck to the bulk tanks,while a single diesel fill line will be installed to refill the tanker truck from the bulk tanks.This arrangement can also be used to facilitate transfers between the Village Council and School bulk tanks,and vise-versa.Each of the three lines from the on/offloading rack will be constructed of 3-inch,schedule 80,welded steel pipe with flanged connections. Both the Village Council and School tanks will be interconnected within their respective cells with flexible fittings,ball valves,welded steel manifold piping,and solenoid valves,which will allow internal and external fuel transfers.Manifold piping will be 3-inch,schedule 40,welded steel pipe with flanged connections.The pipe network will be provided with adequate meters and automated controls so that transferred product volumes can be monitored and documented. A separate,dual-product dispensing station and vehicle turn-in area will be located next to the access road facility (Figures C2 and C3).The dual-product dispensing pipeline will be constructed of 2-inch,schedule 80,welded steel piping with flexible fittings.Product will be transferred to the dispensers with tank-mounted,submersible turbine pumps.Although the current design indicates that the diesel dispensing pump will be sized to allow dual purpose operation as a dispensing pump,as well as the on/offloading rack filling pump,this design may be modified to reduce the number of solenoid valves in the tank farm.This change could result in an increase in the number of pumps installed in the tank farm. SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 16 D&M JoB No.37203-017-220 4.4 OWNERSHIP AND OPERATING PROPOSAL FOR CONSOLIDATED FARM The Village Council and School should maintain a working relationship within the facility.The owner and operator of the proposed bulk fuel facility should be the Village Council.An individual with good mechanical skills should be responsible for operating and maintaining the facility.This person should also be charged with performing routine fuel deliveries to intermediate and day tanks.Because the power plant is located on the adjacent property,it could be beneficial to charge these responsibilities to the power plant operator. Two operating scenarios for the dispensing station should be considered:automated operation and manual operation.Manual operation may require the physical presence of an attendant. Other villages that have a remote dispenser located at the bulk facility have posted operating hours so the attendant can serve customers effectively without undue effort.This may be particularly beneficial if the power plant operator is charged with the operation of the dispenser facility.Another option may be to install satellite controls for the dispenser.This setup allows the customer to pay for the gas/diesel at a fixed location,such as the Village Council Office, where the attendant would electronically set the amount-to be dispensed at the unmanned dispenser.The customer then goes to the dispenser to pump the fuel.The Village Council's preference will need to be included in subsequent design phases. 4.5 CONSTRUCTION CONSIDERATIONS 4.5.1 Previous Geotechnical Investigation The proposed and alternate sites are located along the south bank of the Yukon River.A tributary stream,Minook Creek,enters the Yukon on the northeast side of the Rampart airport. The subsurface soil conditions in Rampart are dominated by alluvial deposits of fine sands and silts.Clay and peat deposits have also been observed in shallow sloughs and old stream channels.Permafrost is typically encountered throughout the Village at depths ranging between 2 to 8 feet below ground surface (bgs),except for areas close to the river where the thermal influence of the river disrupts permafrost formation.These areas may represent the most favorable locations for construction if a topographic survey finds they are outside the floodplain. A geotechnical investigation and foundation study was conducted in Rampart by the Clark Engineering Company during November 1993 (Appendix E).Eight test borings were investigated in areas located southwest of the alternative site (Test Borings 1 and 2)and to the east of proposed site (Test Borings 3 through 8).Boring logs consistently displayed frozen silts SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 17 D&M JoB No,37203-017-220 with high moisture contents at varying depths below the organic mat.These results suggest that a considerable thaw settlement can be expected if the permafrost is degraded. Given the slope and presumed poor soils beneath the proposed site,a slope stabilization design, such as thermosiphons and/or a retaining wall,may need to considered in subsequent phases of the design.Dames &Moore recommends that a geotechnical investigation and topographic survey be conducted at the proposed site prior to proceeding further in the design process.The topographic survey at the proposed site would be necessary to determine slope stability and estimate material volumes.During the field effort,if the investigation at the proposed site is not promising,it may be prudent to consider a second geotechnical investigation and topographic survey at the alternative site.A survey at the alternative site would be required to determine the required top-of-berm elevation that would avoid flooding and to estimate material volumes for that location. 4,5,2 Material Sources Two potential material sources have been identified in Rampart.Both sources are alluvial deposits;one is located on a lateral bar of the Yukon River (Photo 23)and the other is situated along the bank of Minook Creek.An evaluation focusing on test pits and aerial photographs suggests that developing the Minook Creek pit further is not practical.Shallow groundwater would limit the depth of excavation and dense vegetation would be costly to clear in order to mine an appreciable volume of gravel over a large area.The material source at the Yukon River appears to have a significant amount of material and is readily accessible during low river flow periods in the late fall and winter. Four test pits excavated in the lateral bar of the Yukon River indicated that the material consists of sandy gravels with some cobbles,mostly at the surface and associated with the armor layer. Groundwater was observed to be between 1.5 to 1.7 feet bgs.Excavation of this material could be hampered due to freezing during winter conditions.Alternatively,the material could be mined during the summer and stockpiled until needed.In either case,a 404 Wetland Permit would be required from the COE to mine the gravel.The ADOT&PF indicated that they have acquired a permit to mine this source during their upcoming airport project at Rampart,but a separate permit would be required for the proposed tank farm. 4.5.3 Airport Relocation Project Sometime within the next 3 years,the Rampart airport will have an apron expansion and runway resurfacing.The project has contingent funding,meaning that if funding becomes available in 2000,then the project will begin in 2000.Otherwise,the project should begin in 2001. SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 ; RAMPART VILLAGE BULK FUEL UPGRADE 18 D&M Jos No.37203-017-220 Therefore,construction of the holding tank facility at the airport should be postponed until the end of 2001 in hopes of matching project timelines. 4.5.4 Modifications Resulting from Alternative Site Selection If poor soil conditions or property issues prevent construction of the proposed facility on the site located near the power plant,the alternative site appears to be feasible,but would require several changes to the current conceptual design.These changes are associated with a stronger reliance on tanker truck delivery to the village intermediate and day tanks.However,if a dual-product header could be installed at both the river barge site and the airport,leading to the alternative site,truck haul frequency may be reduced to that required only for consumption,rather than for airport delivery as well.An additional 1,000-gallon,double-walled day tank may need to be installed at the power plant in lieu of the proposed pipeline to the power plant.Instead,the Village wishes to investigate the possibility of moving the power plant to a location near the new tank farm to reduce tanker truck deliveries.Dames &Moore recommends that the Village takes into consideration the possibility of utilizing excess heat generated by the power plant to heat their future water tank.In this case,the power plant would be best situated at its current location. Because the alternate site is not restricted by lot size,the tank farm would be constructed with typical berms having a 3:1 slope,which would avoid excess use of expensive geogrid cells. Constructing a tank farm at the alternative site would require a wetland permit.To meet the previously negotiated general COE wetland permit requirements,the tank farm would need to be situated greater than 300 feet from the river's edge.Constructing the proposed tank farm closer than 300 feet from the Yukon River is possible,but would require a specific wetland permit from the COE.At this time,it is not known which permit would be applicable for the tank farm designed for the alternative site. Operating a dispenser at a tank farm located at the alternate site may not be convenient,due to its distance from the office managing the operation.However,dispensing gasoline and diesel at the tank farm can be accomplished using remote electrical connections.The dispenser controls could be located at the Village Council Office,or another fixed location such as the power plant or washeteria.Customers would pay at that location then travel to the remote tank farm to dispense fuel.The control lines could be installed on the power poles leading to the tank farm. Another option would be to provide an attendant at the tank farm at predetermined operating hours during the week.Both types of dispensing scenarios have been used in other remote operations. SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 19 D&M Jos No.37203-017-220 4.5.5 Permitting Permitting requirements will differ between the proposed and alternative site locations.The proposed site is on a hillside within the community and a wetland permit may not be required.If the alternative site,located in a previously undeveloped area along the bank of the Yukon River, is selected,a wetland permit is anticipated.In accordance with Alaska Department of Natural Resources,a determination of archeological or historical significance may also be required. Prior to construction at either location,the completed design will require approval from the Fire Marshall of the Northern Region.Because both the proposed and alternative sites require facilities at the airport,the submittal of a "Notice of Proposed Construction”,Form 7460,to the Federal Aviation Administration (FAA)and a design to ADOT&PF will be required for approval.Similarly,both sites may require a Stormwater Pollution Prevention Plan,written in accordance with the National Pollutant Discharge and Elimination System,to control any runoff from the construction site to nearby water bodies or wetlands.In addition,a Spill Prevention Control and Countermeasures Plan should be prepared for the facility after construction is complete. 5.0 PRELIMINARY COST ESTIMATE A preliminary construction cost estimate was prepared for the proposed bulk fuel tank farm described above.These costs were developed from previous DOE purchasing and construction practices and assumptions.Capital costs were divided appropriately to allocate costs to the users of the proposed co-located tank farm facility. 5.1 ASSUMPTIONS The following assumptions were made for the purposes of cost estimating: °Costs covered in this estimate assume that the proposed site will ultimately be the site selected for constructing the proposed tank farm facility. e Costs assume that the Village will repair the existing tanker truck or purchase a new tanker truck that will haul fuel to and from the proposed tank farm.Because the new airport apron should be constructed prior to completion of the proposed facility,a holding tank,aircraft offloading pipeline,and offloading rack is included in this cost estimate. Details for the new airport offloading facility will be included in drawings of subsequent design phases once Dames &Moore has been provided a copy of drawings from ADOT&PF. SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 20 D&M Jos No.37203-017-220 e In order to make possible a teaming effort with ADOT&PF for material acquisition,a two-phase schedule is assumed.Hence,costs associated with increased mobilization, demobilization,and per diem costs are included to account for construction over two _seasons. e The volume of gravel fill for pad and dike construction,based on this 35%design,is approximately 4,500 cubic yards (cy),and the volume of unclassified excavation is approximately 3,500 cy.These values should increase substantially if the alternative site is selected for construction. e The gravel from borrow sites at the Yukon River is assumed not to have purchasing costs. However,the labor cost to excavate and place the material is assumed to be $15/cy. e Local labor and equipment of the type,and in the quantities listed,would be available for this project.A labor rate of $45 per hour is assumed for the tank farm construction. e Equipment,materials,tanks,piping,and appurtenances can be transported to the site via air cargo planes based in Fairbanks at $10,137.50 per flight (per Lynden Transport,2000) or via barge from Nenana at $0.50/lb.Maximum incoming payload to the airport is assumed to be 40,000 pounds for tank shipments and 41,000 pounds for non-tank shipments.Ten flights are assumed to be required to transport materials to and from the Village. .@ The proposed site is assumed to be the preferred alternative.The following cost estimate is for Site 1,located by the washeteria and power plant. Based on these assumptions,the total estimated cost for the project is on the order of $1,412,877. The relative portions attributed to each tank farm owner is $734,696 for the Village and $678,181 for the School,approximately 52%and 48%of the total cost,respectively.The estimated cost per gallon of fuel is on the order of $20.68/gallon,based on a net volume (90% tank volume)of 69,100 gallons,which does not include the 12,000-gallon holding tank at the new airport.Note that if the construction at the new airport is included in the cost,the total is anticipated to be greater than $1,600,000.Cost estimate spreadsheets are provided in Appendix E. 5.2 LABOR FORCE The project costs are based on the following labor requirements: e One on-site supervisor experienced in all aspects of aboveground storage tank construction,who is also able to operate heavy equipment when required. SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 21 D&M JoB No.37203-017-220 ¢One journeyman pipe fitter/welder,who also is able to rig materials and tanks for unloading and placement at the site. e One operator (local hire). e One truck driver/loader operator (local hire). e Two laborers/carpenters/welder's helpers (local hires). Several Rampart residents are currently enrolled in training programs in areas such as welding and equipment operation.The Village is planning to send these individuals to training courses this summer.A list of the labor force available at the Village will be provided in the final report. 5.3 REQUIRED AND LOCALLY AVAILABLE EQUIPMENT For completion of this project the following equipment will be required: e One dump truck *One small crawler dozer CAT 31 1,or the equivalent e One loader,CAT 950,or the equivalent e Welding equipment e One 20-ton equipment trailer e Crew pickup truck e One fuel tanker truck e One 15-ton crane A list of the equipment available at the Village will be provided in the final report.The current load limit for landing at the Rampart airport is 45,000 pounds,with a 25,000-pound limit for take off (per Lynden Transport,2000).However,this should not be an issue since Rampart is accessible by barge and equipment and materials will likely be shipped via this route. 6.0 PRELIMINARY PROJECT SCHEDULE For scheduling,the project is subdivided into five phases:additional investigation,design, permitting,construction,and regulatory plans.The following Gantt Chart assumes that the proposed tank farm will be constructed during summer 2001.In addition,the chart assumes that construction of the new airport will not begin until after the completion of the bulk fuel project in SITE INVESTIGATION AND PRELIMINARY DESIGN REPORT -DRAFT JULY 2000 RAMPART VILLAGE BULK FUEL UPGRADE 22 D&M JoB No.37203-017-220 2001;therefore,installation of an offloading facility at the new airport is not included in this schedule.This Preliminary Project Schedule is for planning purposes only,and a final project schedule should be coordinated between Dames &Moore and AEA/REG after a site resolution has been drafted by the community.

Introductions and Sign-in: Local Representatives Present Ms.Denise Newman Guests Present Mr.Bruce Tiedeman,Division of Energy Mr.Karl Reiche,Project Manager,Alaska Industrial Development and Export Authority Mr.Gerry Brown,Project Engineer,Dames &Moore Status Report:The following status report includes the agenda covered during the site visit and additional comments from Dames &Moore concerning the bulk fuel upgrade project. Introduction to Bulk Fuel Upgrade Projects -Mr.Bruce Tiedeman introduced the objectives of the Denali Commission in consolidating bulk fuel storage facilities in bush Alaska.Villages typically have several,code non-compliant bulk fuel storage facilities,each under different ownership.Often these facilities have experienced a petroleum release in the past or pose a current fire safety hazard.In the near future,governing agencies (Fire Marshall,Coast Guard, EPA,ADEC,etc.)will not allow operation of these non-compliant tank farms. Offices Worldwide re a1Vann(C7,DAMES &MOOREtb[sastenssan oj A DAMES &MOORE GROUP COMPANY Rampart Village Council December 27,1999 Page 2 The objective of the Denali Commission is to reduce the risk to human health or the environment associated with substandard tank farms.The Denali Commission provides funding for the construction of a single code compliant bulk fuel storage facility that combines the tanks of various owners of the community.By offering this service,the Denali Commission promotes safety in the community and prevents disruption of valuable shipments of fuel. Approximately $25,000,000 has been earmarked by the federal government for construction of consolidated tank farms in rural Alaska.The Denali Commission has prioritized villages to be considered for bulk fuel upgrades and Rampart has been selected as one of the top 20 communities based on need.Out of these 20 villages,between 10 and 12 will be selected to receive funding for construction in the year 2000.The final selection will depend upon site specific criteria contained in the Preliminary Design Report (PDR)and the community's support of the project.Dames &Moore is the contractor responsible for preparing the PDR to be used in the final selection process.Two of the most significant elements that could sway the Denali Commission to select Rampart as one of the funded villages are community involvement and site selection. Selection of Sites Available for a Consolidated Tank Farm -Ms.Newman was asked to identify sites in the community that may be available for construction of a consolidated tank farm facility. Three locations were identified:one near the power plant,washeteria,and school;one near the sewage lagoon;and one near the airport where Rampart currently receives fuel shipments.In the past,Rampart has also received fuel shipments via barge.Dames &Moore proposes to incorporate both delivery options into the conceptual designs for the identified sites.Rampart owns a tanker truck.It was in disrepair during the site visit.To avoid long runs of pipe over the tundra,Dames &Moore assumes that the vehicle will be repaired or replaced so that it will be possible either to deliver fuel to day tanks from a remote tank farm or to deliver fuel to a centralized tank farm from the airport.The following sections describe the proposed sites and the advantages and disadvantages of each. Proposed Site 1 -Site 1 is located on Block 11,Lots 2 and 3 of the USS 5049 survey,along the right of ways of F Street and Fifth Avenue.A property profile on the site indicates that the village owns Lot 3 while Alaska Department of Environmental Conservation (ADEC)Village Safe Water (VSW)could own Lot 2.The site slopes moderately toward the river and is Offices Worldwide G DAMES &MOORELU]A DAMES &MOORE GROLIPCtCOMPANY Rampart Village Council December 27,1999 Page 3 vegetated with trees,grass and shrubs.Because the site is distant from the airport,airport deliveries would have to be trucked to the tank farm and offloaded at a loading rack (Figure 1). Advantages:The advantage of locating a tank farm at proposed Site |is that the primary fuel users,the school,washeteria,power plant,and clinic are located within close proximity such that a pipe distribution system could be feasible.Dispensing gasoline and diesel could be conducted at the site as well. Disadvantages:The topography and the size of Lots 2 &3 limits construction of a large tank farm at the site,one with a full years'storage.Because secondary containment consists of a gravel dike with sloping sides,a topographic survey would be required to determine cut and fill quantities and develop a conceptual layout.As such,the dimensions and proposed layout are not included in the attached drawings. Review of previous geotechnical reports indicated presence of permafrost in the general vicinity.Therefore,deep cuts into the hillside is not recommended due to presumed poor soil conditions or permafrost and this may further limit the size of the containment area for the proposed facility.A geotechnical investigation and survey would need to be conducted at the site prior to designing and constructing the tank farm. The ownership of Lot 2 by ADEC may prevent using the land for a tank farm. Information obtained from the recording district indicates that ADEC VSW (Attachment)may own the land.However,this could not be verified by ADEC. Based on this information,Dames &Moore recommends that a full litigation report be conducted on the site prior to completing the 35 percent design if this site is selected by the community.If lot is not owned by the village,or can not be obtained by the village,then Site 1 should be eliminated from further evaluation. Proposed Site 2 -Site 2 is located adjacent to the sewage lagoon on a small,densely wooded knoll on the hillside above the school (Figure 1).Constructing the tank farm on a steep,heavily vegetated hillside with poor access does not appear practical.The cost of constructing access Offices Worldwide G DAMES &MOORE!ADAMES &MOORE GROUP COMPANYRampartVillageCouncil December 27,1999 Page 4 roads to the site would be very expensive.Geotechnical information of the area indicates abundance of permafrost and unstable soils.Constructing a bulk fuel storage facility on steep hillside underlain with poor soils is not recommended,as the probability of a slope failure is high.For these reasons,Site 2 has been withdrawn from consideration as a potential site. Proposed Site 3 Site 3 is located near the airport on Lot 1,Block 2 of the USS 5049 survey along the right of way of Second Avenue (Figure 1).The Doyon Native Corporation currently owns the property.Ms.Newman indicated that the native corporation owes the village dedication land and it may be possible to obtain a portion of Lot 1 for the proposed project. The site is located along the banks of the Yukon River.An Army Corp of Engineers (COE)High Water Elevation Identification was performed on November 3 and 4,1993.The 1963 ice jam flood was the highest measurable high water of record.Based on survey data collected during the COE site visit,the 1963 flood appears to have been approximately at the elevation of Second Avenue.In reference to Site 3,it appears that the proposed facility is within the floodplain but not to the extent that the secondary containment could not be designed to prevent overtopping of the dikes. Advantages:Site 3 is close to both the river and the airport such that a dual product header could be installed from each location.Because the site is not restricted by lot size,it has not been platted,the tank farm can be sized to provide a full year supply of fuel. For barge transfer,it is advantageous to receive a full year's supply in order to get the fuel at the lowest possible rate. Disadvantages:Because the site is distant from the village,approximately 3/4 mile,distribution of heating fuel will require tanker truck delivery.The village owns a tanker truck but during the site visit,it was observed to be in disrepair.The village should consider refurbishing the truck or replacing it.Note,however,that funds available for DOE projects may not be used to purchase vehicles. Site 3 appears to be in the floodplain.Topographic information could not be obtained for the site,but aerial photography indicates that the elevation of the site is comparable to the Second Avenue.Prior to proceeding to a final design,a Offices Worldwide rCG DAMES &MOORE r beatleartoaasant, Rampart Village Council December 27,1999 Page 5 |ADAMES &MOORE GROUP COMPANY topographic survey should be conducted to ensure that the secondary containment could be constructed above flood level. Site 3 is located approximately 200 feet from the Yukon River.To meet general COE wetland permit requirements,the tank farm would need to be 300 feet from the river's edge.Constructing the proposed tank farm closer than 300 feet from the Yukon River is possible,but would require a specific wetland permit from the COE. Operating a dispenser at a tank farm located at Site 3 may not be convenient due to the distance to the office managing the operation.However,dispensing gasoline and diesel at the tank farm can be accomplished using remote electrical connections.The dispenser controls could be located at the village council office or another fixed location such as the power plant or washeteria.Customers would pay at that location then travel to the remote tank farm to dispense fuel.The control lines could be installed on the power poles to the tank farm.Another option would be to provide an attendant at the tank farm at predetermined operating hours during the week.Both types of dispensing scenarios have been used in other remote operations. Discussion:Currently,Rampart School is not open due to low attendance but this is assumed to be only a temporary situation.Therefore,the proposed facility includes storage volume for the schools heating fuel. A dual product dispensing tank,dual product dispenser,and a loading rack for the tanker truck are proposed for the facility.Two operating scenarios for the remote dispensing station should be considered,automated operation or manual operation.Manual operation may require the physical presence of an attendant.Other villages that have a remote dispenser located at the bulk facility have posted operating hours so the attendant can serve customers effectively without undue effort.Another option may be to install satellite controls for the dispenser.This setup allows the customer to pay for the gas/diesel at a fixed location,such as the village council office,where the attendant would electronically set the amount to be dispensed at the unmanned dispenser.The customer then goes to the dispenser to pump the fuel. Offices Worldwide gan(CG DAMES &MOORE E eewcaua,A DAMES &MOORE GROUP COMPANY Rampart Village Council December 27,1999 Page 6 Because Rampart can receive fuel either by barge or by airplane,the conceptual design of for the site alternatives includes both modes of delivery.In addition,it is recognized that the village owns a tanker truck that can be used to either deliver fuel to day tanks from Site 3 or deliver fuel from the airport to Site 1.To facilitate fuel transfers to and from the tanker truck,the conceptual designs include loading racks (Figure 2). Community Information Worksheet -Due to time constraints,Dames &Moore could not obtain some of the information required to prepare a high-quality PDR during the site visit.Attached is a checklist of information that is required for the report.Dames &Moore would like to thank council members in advance for ensuring that the requested information is returned in a timely manner.If there are any questions or problems,Mr.Gerry Brown of Dames &Moore will assist in any means possible. Proposed Operating Scenario -The following issues concerning the ownership and operation of the proposed facility need to be addressed by the community. e The owner and operator of the proposed bulk fuel facility should be the Village Corporation and it should be maintained and supervised by a local individual with good mechanical skills. e Gasoline and diesel dispensing should be conducted at the proposed bulk fuel facility. The village council should indicate their preference for automated or manual fuel dispensing systems. e The village and the school should maintain a working relationship within the facility.The proposed tank farm should maintain separate fenced areas to segregate tanks according to ownership.Each entity would be provided secured systems to prevent unauthorized transfers from occurring from their storage tanks. Request for Community Decision:As mentioned previously,community support is essential for the Village of Rampart to be considered for funding.The proposed site location and operation scenario presented above are Dames &Moore's recommendations based on code compliance,DOE specifications,and the Denali Commission evaluation process.Although Offices Worldwide reckG DAMES &MOOREret|A DAMES &MOOREGROUP COMPANYRampartVillageCouncil December 27,1999 Page 7 Dames &Moore believes that these recommendations would result in the highest rating possible in the PDR evaluation process,the community of Rampart has the final word on site selection and operation scenario of the proposed facility.On behalf of the Division of Energy,Dames & Moore requests that the Rampart Village Council conduct a meeting to discuss the options presented above and/or develop other options based on community involvement.Dames & Moore and the Division of Energy will be available to provide guidance in your decisions. The attached Community Involvement Checklist is a request for information which is required to complete the PDR.Please complete and return Checklist along with a written statement concerning the community's decision on site selection and operating scenario.Once the community has selected a site and operating scenario agreed upon by the council,a design layout will be drafted and the PDR completed for submittal to DOE and the Denali Commission.

There have been numerous spills associated with this tank farm.One spill occurred due to an open valve and migrated to a drainage channel.The fuel collected in a small pond where the product was collected by pumping.A more recent spill occurred while transferring fuel from a tanker truck to the farm.Contaminated soil upgradient from the communities new water well was excavated and stockpiled on site.New day tanks at the village clinic and washeteria were observed have overfill spills despite installation of spill containment appurtenances. Tanks #3,4,&5 are old BIA tanks and should not be reused.Tanks 1,2,&6 are newer tanks and could be reused. Notes on TF #2 Tank Farm #2 is consists of a single tank that had not been installed at the time of the site visit. The Trading Post,the community store,acquired the tank to sell gasoline but has not managed to get it operating. Currently,gasoline is sold for cost at a local residents home.The fuel is purchased from nearby community and transported to the village via boat. Notes on TF #3 TF #3 is the ADOT tanks at the airport maintenance building and is outside the scope of our project.The heating oil tank is a code compliant Ace Dike Tank.Two other ADOT tanks are stage along the apron to store/dispense Avgas. These two tanks are not code compliant. Notes on Tanker Trucks The village owns two tanker trucks and one tanker trailer.Currently,the tanker trailer is used to transfer fuel. A local construction contractor is paid to tow the trailer from the airport to the tank farm.The practice does not appear to be safe.The tanker truck was observed to have several welds that have been damaged and the means of hooking up to the trailer requires innovation as there is no tongue.The tanker truck at the tank farm does not appear operable.The tanker APPENDIX C USCOE HIGH WATER ELEVATION IDENTIFICATION ALASKA DISTRICT CORPS OF ENGINEERS FLOOD PLAIN MANAGEMENT SERVICES HIGH WATER ELEVATION IDENTIFICATION Community:Rampart DateofVisit:November 3-4,1993 GeneralObservations/Comments:Rampart is located on the southbankoftheYukonRiverapproximately75milesupstreamfromisconfluencewiththeTananaRiverand100airmilesnorthwestofFair.

Scate "=IMILE _Date Introduction A reconnaissance materials investigation was performed atRamparton8/28/80 by Dave Stanley,Engineering Geologist andBobConnolly-Conover,Driller-Operator and on 10/30/80 by TomOttley,Engineering Geologist.'The purpose of the investiga-tion was to locate a source for surfacing and -embankment material.Two sites were examined and sampled.Potential Borrow Area #1 is located on a lateral bar in the Yukon River, immediately northwest of the runway.Four test pits were handexcavatedatthissiteandthreefieldsamplesweretakenand returned to Anchorage for testing.Potential Borrow Area #2 islocatedaboutonequartermilesoutheastoftherunway.BorrowArea#2 was used as a source of material during construction of the Rampart Airport,and is known as the Minook Creek Pit. Three test pits were excavated in an area east of the pit and two samples were taken from the east edge of the existing pit and returned to Anchorage for testing. Potential Borrow Area #1 This site is located on a lateral bar in the Yukon River,at a location just upriver from the village of Rampart.ThepotentialborrowareaextendsfromthemouthofMinookCreek to a point about 4000'downriver towards the village.Fourtestpits(TP 1TO,2TO,3TO,and 5DS)were excavated at this site.The test pits indicated sandy gravels with abundant cobbles present.An armor layer of cobbles has formed on the surface of the bar.The underlying material was indicated to be sandy gravel with some cobbles.The gradations for the samples taken from the materials at this site should not beconsideredtobeaccuratewithrespecttotheamountofplus3 inch.The presence of the armor layer makes representative sampling difficult. Groundwater was encountered in TP 1TO and in TP 5DS at 1.7' and 1.5'respectively.Due to fluctuating river levels,thissitemightbefoundtobeunder.water at almost any time ofyear.Normally,:the site could be expected to be exposed during late fall and winter months. Frozen ground was encountered,in the form of seasonal frost,in the three test pits which were excavated on 10/30/80.NoseasonalfrostwasencounteredinTP5DS,excavated 8/28/80. Substantial difficulty may be encountered if the material at this site is excavated when frozen. Potential Borrow Area #2 This site is located about one third mile southwest of the runway,in alluvial deposits of Minook Creek.The site was --2- used previously during construction of the Rampart Airport.Any use of this site would require authorization of the owners (Doyon Regional Corporation,Baan O Yeel Kon VillageCorporation),the BLM,and possibly additional agencies. A surficial examination was made of the area,and two samplesweretakenfromthesouthwestsideoftheexistingpit.The pit was reported to have had a high water table during itsprevioususe.Standing water was observed in the lower por- tions of the pit during this investigation in August,1980.Asurficialexaminationofthefloorandtheperimeterfacesof the previously used area suggests that Little material re- mains above the water table in the existing pit.In order to obtain the required quantities,it will be necessary to work below the water table,or to expand the limits of the pit. Expansion of the pit to the east or south is not recommended, based on interpretation of aerial photography and based oninformationfromthreetestpitsexcavatedeastoftheexist- ing pit (TP 1DS,2DS,3DS).Due to the shallow water table, any expansion of the pit will probably require an extensive area of clearing and stripping,since only a limited amount of material is above the water table.Groundwater should be expected at shallow depths,especially during spring and during periods of heavy rainfall. No evidence of frozen soils was seen at this site,during this reconnaissance investigation,but frozen soils may be encountered in any excavation in this area.Rampart is Llocat- ed in area which has been mapped as being underlain by discontinuous permafrost.

PERSONNEL This project team consisted of three people:Mr.Edwin S. Clarke,P.E.;Mr.Patrick L.Butler,E.I.T.;and Mr.James Orrison.Mr.Clarke was the project manager who managed thelogistics,provided technical supervision,and reportediting.Mr.Butler was the project engineer who performed the field investigation,logged the test borings,performed the laboratory testing and prepared the report.Mr.Orrison, a long-time Rampart resident,provided assistance in locating the borings,operated the drill,and the Cat used to relocate the drill. FIELD PROGRAM On November 17,1993,Mr.Clarke and Mr.Butler traveled to Rampart in the charter aircraft used to transport the drill. During this trip,they unloaded the drill,observed site terrain conditions and discussed site locations with the surveyors.Mr.Butler remained in Rampart to conduct the site investigation. Drilling was performed by Mr.Orrison with our Mobile B-24 skid mounted drill,using 4 inch O.D.solid stem augers.All material brought to the surface was continuously monitored by Mr.Butler,an experienced geotechnical engineer.The drill was towed to the sites with a John Deere 458 tractor rented from the City of Rampart. The test borings were located on the lots.Since no house sites were located prior to the field investigation,it was decided to drill in representative areas to gain a general knowledge of the subsurface conditions.Test borings 1 through 8 were made on lots marked out by the surveyors.Test Boring 9 was made on Jenney Joseph's lot.At the time of the investigation.it was not clear if she was to have a house built.It was decided that a boring would be made near her house site on the chance that she would have a house built. 1 The test borings are located as indicated on the enclosed survey plat (Appendix B ).This plat was prepared by Amtec,the survey contractors.The boring locations were supplied byClarkeEngineering.The soils encountered in the test boringsareshownontheenclosedboringlogs(Appendix A ).The logs .show specific conditions encountered at the test locations;subsurface conditions may vary in other areas. Permafrost was encountered in all test borings at a depth ranging from 2 feet to 14 feet. TESTING PROGRAM Samples were taken at the top of the frozen layer and one or more at random depths to quantify the moisture contents of the frozen material.The selected samples were returned to Clarke Engineering Company's Laboratory for moisture content analysis,which was performed in general accordance with the State of Alaska Method T-5 (Alaska Test Methods,Materials Section,T-5).Some of the samples were sent to the laboratory of the A.W.Murfitt Company to determine the clay fraction in the sample.This hydrometer analysis was performed in general accordance with ASTM D422.The results of these analyses are shown on the enclosed grain size distribution sheets.which are located with boring logs 5 and 6. GENERAL SITE CONDITIONS The village is located on a north-facing slope overlooking the Yukon River.The vegetation consists of mixed spruce,birch and poplars with willows between the larger trees.Most of the lots are forested and undeveloped,except for Lot 5,Block 9,which has an abandoned house on it.Lot 4,Block 9 has been cleared and used for a dog lot,but at the time of drilling was not in use. GEOLOGY The basic geology of the Rampart area is dominated by the fact that the town is built on the alluvial fan of a tributary of the Yukon River and the flood plain of the Yukon River itself.An alluvial fan may be comprised of sediments from the size of cobbles down to sub-silt size particles.There are also specific deposits of wind-blown loess in the Rampart village area.Underlying the relatively recent sediments is most likely a Jurassic/Mississippian mafic volcanics and sedimentary rock unit. The primary geologic concern in the area of the Rampart townsite is the Kaltag Fault.The Kaltag is an active fault whose inferred course lies directly below Rampart.This fault is capable of producing magnitude 6 or greater earthquakes (Active Faults of Alaska,p.81 ). The village of Rampart appears to be underlain by continuouspermafrost.The soils encountered in the test boringsconsistedentirelyofsiltswithsomeclayencounteredintwo of the samples.During the soils investigation,no massive ice in the form of ice lenses or wedges was encountered.Some visible ice was encountered ina few borings.The moisture content of the frozen soils indicates that upon thawing,asignificantamountofthawsettlementwilloccur. SUBSURFACE TEMPERATURES As part of the field investigation,an attempt to determine the temperature of the frozen soils was made.To do this,l inch PVC pipe was installed in Test Borings 1,2 and 5.Due to the air temperature at the time of drilling (-208 deg F),and the rapidly freezing auger cuttings used to backfill the 4 inch drill hole,it was impossible to completely backfill thehole.The air pockets created by the bridging allowed theminus28degreeairtoaffectthefinaltemperaturereadings. When the thermistors were'read,the values give were obviously erroneous.Therefore,it is impossible to provide temperature data with any real meaning.A conversation with Mr.Ed Yarmack,who designed the thermopiles supporting the school, indicated that the permafrost is relatively warm,at approximately 32 deg.F. LOCAL FOUNDATION SYSTEMS In Rampart.observations were made on the types of foundations used for local buildings.A raised foundation is used for most buildings.One older building was constructed with an on-grade foundation.This building exhibited a significant amount of settlement in the central portion of the building. The school is supported by thermopiles.A conversation with Mr.Ed Yarmack of Arctic Foundations Inc.indicated that the thermopiles under the school were designed with a high capacity for heat removal.This was to maintain the ground in a frozen condition.The new clinic building utilizes a post and pad foundation. CONCLUSIONS AND RECOMMENDATIONS Seismic Rampart is located in a seismic Zone 3 as defined by the UBC, and the houses should be designed accordingly.The soils have a high liquefaction potential in an unfrozen condition.However,as long as the soils remain frozen,the risk of liquefaction is nonexistent. Foundation Recommendations The soils encountered in the testing program will not supportaheatedbuildingwithaconventionalspreadfootingfoundation.Heat from a building will thaw the underlyingsoils,causing settlement.Hence,the use of a post and padfoundationdesignisrequired.The use of an insulated embankment will reduce the amount of melting and seasonalfrostheave.Figure 1 is a conceptual drawing of this system. Embankment Construction The area under the pads should be cleared down to mineral soil and made level.Four inches of extruded polystyrene insulation should then be placed on the cleared area.fMThis insulation should extend 4 feet beyond the perimeter of the building.The insulation should be placed in two layers with staggered joints.A minimum compressive strength of 35 pounds at 1@ percent deformation is required.Wooden dowels should be used to prevent slippage of the insulation during placement of the gravel fill.If this work is performed when air temperatures are above freezing,the insulation placement should be accomplished within several hours of clearing. Two feet of gravel fill,186%passing the 3 inch sieve and not more than 12%passing #288 sieve,should be placed over the insulation,using end-dumping techniques.This fill should be placed in 1 lift and compacted to 95%of optimum density. Care should be taken to avoid damaging the insulation.This gravel fill should extend 2 feet beyond the insulation. Foundation Design The building footings can be designed on the basis of 2890 pounds per square foot.Due to the warm nature of the permafrost,and the 3-foot-plus snow depths frequentlyencounteredininteriorAlaska,the buildings should have a clear air space of at least 3 feet.This air space is not to be enclosed at any time. The foundation system will need to be braced against lateral loads such as winds and _earthquakes.Provisions forrelevellingthesystemshouldbemade,as some movement from differential settling and frost heave will occur.The design of the foundation system should prevent damage to the house as this differential movement occurs. The post and pad foundation is recommended due to the low cost and ease of construction in remote areas.Wood within 6 inches of the ground should be treated lumber and large glu-lams should be used to prevent damage to the house during differential settlement. Shipping Considerations Building material can be loaded on a barge and shipped toRampartduringthesummer.Or,according to Jim Orrison, there is a winter road that can be opened.The only other wayofmovingmaterialinisbyairfreight. Alternative Foundation Types For any type of foundation other than post and pad,costs would be prohibitive.The depth of the active layer,the physiographic location,and conversations with Mr.Ed Yarmak, indicate that this area is underlain by warm permafrost and that thermoprobes will be required to maintain the ground ina frozen condition.Calculations indicate that a minimum of 9 thermopiles at an installed cost of approximately $4898 each May be required to support a typical house.Additionally,a Grill rig would have to be brought into the village,such as was done for the school. Onsite Wastewater Disposal Systems The use of an onsite wastewater disposal systems is not recommended on these lots.ADEC requires a minimum of 6 feet between the bottom of the septic system and permafrost.Most borings indicated that the depth to permafrost was less that 6 feet.On the lots where permafrost was encountered deeper,a semi-mounded system would have to be used.Our investigation indicated that the depth to permafrost is highly variable. This would would require a test boring at each on-site system location., MATERIAL SOURCES Conversations with Mr.Jim Orrison,a local equipment operator,indicate that gravel can be mined at a gravel bar near the airport.He indicated that this gravel bar was exposed in July,when the river level is down.According to a DOT materials report prepared for the airport improvements (Rampart Materials Investigation,19898),the river bar consists of sandy gravel with some cobble size rocks. The DOT report mentions a second source called the Minook Creek Pit.The pit is an alluvial deposit of the creek. According to the DOT report,the pit may have to be expanded, before use.Since this report was made before the expansion of the runway,the pit may be played out.Additionally.the local mine is a source,if the locally available equipment can ford the creek. CLOSURE In order to ensure that this project is constructed in accordance with the recommendations in this report,it is advised that the design and construction be reviewed and observed by personnel from Clarke Engineering Company. Personnel are available in accordance with our standard schedule of fees. CLARKE ENGINEERING COMPANY vieparea sy Gilt Lhe, Patrick L.Butler,E.I.T.
