PRELIMINARY DESIGN REPORT DRAFT MARCH 2000 CITY OF LOWER KALSKAG BULK FUEL UPGRADES ill D&M JoB No.37203-015-218 1.0 INTRODUCTION This Preliminary Design Report (PDR)presents the results of our data review and initial site investigation for the proposed Bulk Fuel Upgrade for the Village of Lower Kalskag,Alaska. This report was prepared based on information gathered during our site visit,as well as information obtained from Aeromap,Inc.and the State of Alaska Department of Community and Economic Development (DCED),Alaska Department of Transportation (DOT),and the Alaska Energy Authority/Rural Energy Group (AEA/REG). On October 28 and 29,1999,Mr.Pat Butler of Dames and Moore conducted a site visit to Lower Kalskag and Upper Kalskag.The purpose of the site visit was to gather information and community preferences on potential sites for the consolidated bulk fuel facilities,to determine the current fuel use and distribution,to evaluate the existing conditions,and to ascertain community preferences for the operation of bulk fuel facilities.This information was used to prepare this PDR.. Each of the existing fuel farms was documented by a visual inspection and photographed for future reference.The suitability for incorporation of the various system components into an upgraded and consolidated facility was evaluated.A conceptual design report was submitted to AEA/REG on November 23,1999,prior to preparing this PDR and is attached as Appendix A. This report only addresses the proposed bulk fuel upgrade in Lower Kalskag.A separate report was prepared addressing the bulk fuel upgrade for Upper Kalskag.The supply for the elementary school is addressed in the PDR for Upper Kalskag. 2.0 SITE DESCRIPTION AND EXISTING FACILITIES This section summarizes the results of our site investigation,and provides a description of the condition of each of the tank farms and facilities evaluated as part of this project.The layout of the community and the location of each of the existing tank farms discussed in this report are shown on Sheet Cl (Appendix B). 2.1 SITE DESCRIPTION:LOWER KALSKAG The Village of Lower Kalskag is located on the Kuskokwim River between Bethel and Aniak.It is approximately 3 miles downriver from Upper Kalskag.The airport is located north of Lower Kalskag between the two villages.The high school is located south of the airport.The power plant that supplies power to both villages is located in Lower Kalskag.Even though a road PRELIMINARY DESIGN REPORT -DRAFT MARCH 2000 CITY OF LOWER KALSKAG BULK FUEL UPGRADES 1 D&M JoB No.37203-015-218 connects the two villages,they are two separate villages with only the high school,airport,and power plant as shared facilities. 2.2.EXISTING TANK FARMS AND FACILITIES The high school and a private tank farm are located between Upper and Lower Kalskag:they are addressed by the PDR for Upper Kalskag.Within Lower Kalskag there are three bulk fuel tank farms:AVEC,the elementary school and the City of Lower Kalskag.The users of fuel are listed in Section 3.1. Tank Farm 1 AVEC:The Alaska Village Electric Co-Op tank farm consists of 12 vertical tanks (Photos 8 and 9).The sizes and volumes are listed in Table 1.The tanks store fuel used to produce power.The tank farm is located next to the power plant across the street from the elementary school and next to the water plant.The fenced site has a containment berm around the tank farm,but the quality of the liner is unknown.The fuel is piped directly to a day tank in the power plant building.It appears that the tanks lack proper emergency vents,fill-limiting devices and level gages.The tanks are supported on wood platforms.The tanks are marked with the gallonage,and appear to be maintained. The piping is welded steel with flanged fittings.The tanks are manifolded together.Gate valves are used.No flex connections were noted.A barge header for bulk deliveries runs from the river to the tanks (Photo 11). Tank Farm 2 Elementary School.The elementary school in Lower Kalskag is supplied with fuel from underground tanks.The estimated size is listed in Table 1.It is believed that these tanks do not meet current ADEC 18AAC78 regulations for underground tanks.A barge header, which runs parallel to the AVEC header,is used to fill these tanks.No detailed inspection of the buried tanks was made. Tank Farm 3 City.The city runs a tank farm,which supplies fuel for the city's use and for retail sales.There are 3 cylindrical and 2 rectangular horizontal tanks inside the diked area which store gasoline and diesel fuel.The sizes and volumes are listed in Table 1.There are a couple of smaller tanks,500 to 1000-gallons,outside the diked area which appear not to be in use.The tanks are supported either directly on the ground or by wood blocking.Only Tank #3 has a tank saddle.The tanks are inside a diked area.It is not known if the diked area has an impermeable lining.The entire tank farm is fenced.Also,within the fenced area are the operating shack and dispensing stations.There is a separate dispensing station for each product (Photos 4 and 5). Tank Farm 3 is located near a bluff overlooking Kuskokwim River.The tank nearest the river is PRELIMINARY DESIGN REPORT -DRAFT MARCH 2000 CITY OF LOWER KALSKAG BULK FUEL UPGRADES 2 D&M JoB No.37203-015-218 approximately 40 feet from the bluff.The tanks lack code-compliant emergency vents,level gages and fill-limiting devices.No barge header exists for this tank farm. The city operates a tank truck.This is a flat bed truck with a 500-gallon tank strapped to the bed of the truck.The tank truck is filled from the dispensing station (Photo 7).A small gasoline driven pump is used to pump fuel from the tanks on the truck to the receiving tank.No secondary containment is used during fuel transfers.- Each of the large rectangular tanks is connected to a dispensing station.At the tank,the draw pipe is l-inch diameter iron pipe.Just in front of the tank,the pipe is connected to a filter element.The distribution line from the filter to the dispensing station is a rubber hose (Photo 3). 2.3 REUSE OF EXISTING TANKS AND PIPING The AVEC tanks are planned for re-use.Some of the City's horizontal tanks could be reused. However,only one of the horizontal tanks has proper tank saddle supports.All tanks in the City Tank Farm lack proper emergency vents,fill-limiting devices,and other appropriate fittings. Based on the above,no reuse of the city's tanks would be assumed.None of the piping,normal vents,or other fittings are worth salvaging. 2.4 LAND OWNERSHIP The City of Lower Kalskag is the apparent owner of the land.The title report is attached in Appendix E. 3.0 CURRENT &FUTURE FUEL STORAGE AND USAGE According to AVEC,the current AVEC storage capacity is adequate.The City's storage capacity is inadequate according to the mayor.Fuel is usually delivered by barge twice a year to Lower Kalskag.Table 1 summarizes the existing tanks.The current gallons of fuel usage and volume delivered by barge are listed in Table 2.

MARCH 2000 D&M JoB No.37203-015-218 PRELIMINARY DESIGN REPORT -DRAFT CiTY OF LOWER KALSKAG BULK FUEL UPGRADES 4 3.1 CURRENT USAGE Table 2 lists the current barge deliveries for the City and the volume used as indicated by AVEC. The mayor indicated that some years the city had to buy approximately 10,000 gallons of diesel from AVEC to get through the winter until the spring barge.The barge delivery company was contacted and the amount delivered was obtained.The yearly use for the city was estimated as the volume delivered plus the amount purchased from AVEC. Uses and Local Delivery:In Lower Kalskag there are 4 groups that use fuel:the school,the city,AVEC and the general population. AVEC:The power plant for both Upper Kalskag and Lower Kalskag is located in Lower Kalskag.It uses fuel for power generation. School:In Lower Kalskag,there is an elementary school which uses diesel primarily for heating of the buildings and,if needed,backup power generation.As developed in the conceptual design,the bulk fuel storage for the schools was placed in Upper Kalskag,so the pertinent bulk fuel usage and storage requirements were addressed in the PDR for Upper Kalskag. City:The fuel used by the City of Lower Kalskag is used for heat and as fuel for vehicles.The city runs a water plant and community center.The general population in Lower Kalskag buys its fuel from the City.This fuel is used for heat,trucks,4-wheelers,and snowmachines.The city operates the tank truck that is used to deliver fuel to residential day tanks. Bulk Deliveries:Bulk fuel deliveries to Lower Kalskag are exclusively by barge.The barge anchors along the riverbank and delivery is made by a hose to the City Tank Farm.No deliveries are currently made by air.A piped barge header fills the school and power plant tanks.These headers are co-located at the same spot on the river bluff.The pipes follow the same routes. 3.2 FUTURE USE Within the Village of Lower Kalskag,it is unclear if the future demand for fuel will increase. Little increase in fuel consumption is anticipated.Sizing of the secondary containment for the proposed tank farm includes enough space for an additional tank for the City and three vertical tanks for AVEC to account for any unanticipated growth. PRELIMINARY DESIGN REPORT -DRAFT MARCH 2000 CITY OF LOWER KALSKAG BULK FUEL UPGRADES 5 D&M JoB No.37203-015-218 4.0 PROPOSED FUEL SYSTEM The goal of this report is to present a conceptual design for a consolidated bulk fuel facility in the community that is code-compliant and provides adequate storage capacity for the community.To meet the code requirements,three major items must be addressed:1)provide secondary containment for the tanks,2)provide the appropriate fittings and appurtenances on the tanks,and 3)ensure that proper separation distances are met.Additionally,the method of distributing the fuel to the users must be addressed.To meet the storage requirements,the anticipated future needs and past uses must be known.These anticipated needs and past use was discussed in Section 3.The appropriate fittings and appurtenances will be designed during the 65%to 100% design stages.The storage volume,separation distances,the secondary containment system,and distribution method are addressed in this PDR. 4.1 SECONDARY CONTAINMENT Due to the volume stored,self-diked or double-walled tanks cannot be used to provide the required secondary containment.The typical method of providing secondary containment is to use an earthen berm with an impermeable liner.The tank farm will need to be divided into two cells:one for the City's tanks and one for the AVEC's tanks.The intermediate berm used to separate the two cells will be the full height.This will allow the AVEC tanks to be independently fenced. The loading rack must be separated from the bulk tanks and the dispenser.The loading rack will require secondary containment sized to contain a release from the tank truck. 4.2 FACILITY DESCRIPTION 4.2.1 Tanks The proposed volume for the AVEC cell is the same as currently available since the current tanks are planned for reuse.For the City,the volume was taken as the sum of the total volume delivered plus an additional 10,000 gallons.This volume was used to determine the required number of tanks for diesel and gasoline utilizing 90%of the total tank volume.The city's portion will have a dispensing tank for each product.This gives the tank farm a total gross design storage capacity of 249,000 gallons:99,000 gallons of diesel for AVEC;90,000 gallons diesel for the City;and 60,000 gallons gasoline for the City.This volume should allow for one fuel barge delivery per year.The arrangement of the tanks is shown on Sheets C2 and C3. PRELIMINARY DESIGN REPORT -DRAFT MARCH 2000 City OF LOWER KALSKAG BULK FUEL UPGRADES 6 D&M JoB No.37203-015-218 4.2.2.Day-tanks and Fuel Distribution System To serve the needs of the community,the tank farm will need to distribute fuel to the users. Gasoline and diesel fuel will be dispensed at a dispensing station.The station will have one dual product dispenser.A short road for access to the dispensing stand will be needed.A vehicle using the dispensing station is required to be completely on the property during fueling.This moves the tank farm slightly farther west from the existing property line.A separate loading rack will be constructed for filling the tank truck. Fuel for the power plant will be piped to the power plant.The pipe route shown on the plans follows existing property lines;however,buildings and other structures may exist on and across property lines.A site survey will be needed to resolve this detail and determine the pipeline's alignment.A 5,000-gallon double-walled intermediate tank will be installed outside the power plant to limit the number of transfers. At the school building,a 5,000-gallon double-walled intermediate tank would be installed as part of the planned upgrade for Upper Kalskag. 4.2.3.Fuel Line Alignment and Barge Header Fuel from the barge would be delivered at a new barge header on the bank of the river.A separate pipeline each for gasoline and diesel would be used.The fill line would run from the beach to the tank farm.Only one header will be constructed.The valving will be arranged to either fill the AVEC tanks or the city tanks. 4.3 SITING The site chosen was the site preferred by the Mayor.The site is located away from the residential portion of the village.The site is about 400 feet from the river.This was done to locate the road fill 300 feet from the river in accordance with the General permit from the USACE.The tanks were then located with sufficient separation distance from the property line.The site appears to have plenty of room for the secondary containment and other appurtenances,so the layout is not constrained by space limitations. The required separation distances can easily be met for this site.It is required that an unprotected dispensing tank be 75 feet from the property line.The bulk tanks must be a minimum of 40 feet from the property line.The loading rack must be separated from the dispensers and be 25 feet from the property line.This location requires the construction of an access road that extends the current easement. PRELIMINARY DESIGN REPORT -DRAFT MARCH 2000 CITY OF LOWER KALSKAG BULK FUEL UPGRADES 7 D&M JoB No.37203-015-218 4.4 OWNERSHIP AND OPERATING PROPOSAL FOR CONSOLIDATED FARM At present,there are 2 operators who use or sell fuel,AVEC and the City of Lower Kalskag. The farm is divided into two cells.As outlined in the conceptual report,the City will continue with the retail sales of fuel.The goal of this project is to develop a facility that consolidates all tanks inside one secondary containment system.The City will assume the responsibility for the maintenance,operating the dispensers,fuel delivery,and general administrationon a day to day basis,of the tank farm.This is recommended because the city's operator will be on site daily, selling and delivering fuel.For the AVEC side,the power plant operator will oversee the AVEC tanks.Part of the AVEC power plant operator's duties will be to inspect the AVEC tanks once a week.Any large spills should be noted and immediately responded to by the City's operator. 4.55 CONSTRUCTION AND SCHEDULING CONSIDERATIONS 4.5.1 Final Design Issues Flooding:As required by the COE permit,the fuel storage tanks must be located or designed to withstand the 100-year flood.The 100-year flood level is not known,but the highest flood level to date is known and that was the elevation used for design purposes.The flood marker with the recommended building height,based'on flooding in 1964,is approximately 5 feet above the existing grade.Since no survey data was available,the site is assumed to be at the same elevation as the town.To prevent the tanks from floating,the floor of the dike was set 4.5 feet above grade.This value in conjunction with the 1 foot of tank saddle height was used to account for the unknowns of the terrain and to provide a conservative cost estimate.This value may be changed once the survey and final design is complete.Additionally,the tanks will be anchored to concrete pads to help prevent floating. 4.5.2 Geotechnical Two reports from DOT were obtained with soils information from the airport and material sites. Boring logs within the village were also obtained.These reports are attached as Appendix C. The reports indicate that the subsurface conditions appears to be adequate to support the tank farm.Based on the information available,the depth of overexcavation was estimated for the cost estimate at 1 foot to remove any deleterious material on the surface,such as peat.This depth may be increased or decreased based upon the results of a geotechnical investigation. In the soils reports for the airport and material sites that were obtained,permafrost was not mentioned.The soils report for the HUD housing indicated an area of discontinuous permafrost. However,most of the utilities in the village are buried,which is normally done in areas where PRELIMINARY DESIGN REPORT -DRAFT MARCH 2000 CITY OF LOWER KALSKAG BULK FUEL UPGRADES 8 D&M Jos No.37203-015-218 permafrost is not a concern.Evidence of permafrost damage to existing structures was not observed or reported.However,for the purpose of the cost estimate,4 inches of insulation were included in the pad design.This,in conjunction with the thick fill section,should minimize problems.Based on the information to date,other means of dealing with the issue of permafrost are not needed.The main concern will be frost heave of the underlying silts.The insulation should help to minimize this.A more detailed geotechnical investigation of the proposed site should be conducted prior to the 65%design.- 4.5.3.Material Sources During the site visit,no material sites were inspected.However,gravel seems to be readily available.The older geotechnical reports listed a gravel bar that was investigated for use in upgrading the runway.There is a rock quarry on the mountain outside of Upper Kalskag that could also be used.The Calista Corporation owns the subsurface rights.Prior to final design,a borrow source should be selected. 4.5.4 Survey Prior to the completion of the 65%design,the site will need to be surveyed to establish the property lines and obtain topographic information.This will be needed to address the volume of fill required and the flood elevation.It appears that sufficient monumentation is available for this.The airport is currently scheduled for an upgrade and the recovered monumentation from it can be used for control. 4.5.5 Schedule March to April 2000 65%design April to May 2000 Geotechnical Survey/Investigation May to June 2000 100%design April to July 2000 Permitting and Procurement July to October 2000 Construction of pad.Placement of City tanks. June to September 2001 Placement of AVEC tanks and final piping This aggressive schedule is based on doing the geotechnical investigation as soon as the snow is gone.The geotechnical investigation is assumed to be conducted with a locally available backhoe.It is anticipated that permitting and procurement could be started after the 65%design is reviewed and approved by AEA.Because no City tanks are to be reused,the existing tank farm can remain in operation during the construction of the new farm with no pressure to haveit operational before freeze up.Since the AVEC tanks are planned for re use,it is recommended PRELIMINARY DESIGN REPORT -DRAFT MARCH 2000 City OF LOWER KALSKAG BULK FUEL UPGRADES 9 D&M JoB No.37203-015-218 that the pad be constructed this summer and the tanks moved next summer.A second summer will allow for more time to complete the project and allow for delays in design and shipping. 5.0 PRELIMINARY COST ESTIMATE A preliminary construction cost estimate was prepared for the bulk fuel tank farm described in the previous section.These costs were developed from previous Division of Energy purchasing and construction practices and assumptions.Where practical,vendors were contacted for costs. 5.1 ASSUMPTIONS One of the most critical assumptions made during the design process was concerning the cost of gravel.Since the pad was elevated for flooding concerns,this increased the volume of gravel required.A call to Knik Construction indicated that the cost per cubic yard was $25.00.An additional $5.00 was added to the cost for delivery to Lower Kalskag.The cost estimate has included shipping from Anchorage,the assumed port of embarkment. Based on these assumptions,the total estimated cost for the project is $3.1 million.Cost estimate spreadsheets are provided in Appendix F. 5.2 LABOR FORCE Key positions for this project would be the foreman,equipment operators,and welders.The local residents can supply the equipment operators and general laborers.The project foreman and welders are assumed to be non-local hires. 5.3 LOCAL EQUIPMENT The cost estimate included the repair of the equipment prior to start of the project.Currently,the airport is planned for upgrade in the summer of 2000.The equipment for this upgrade could be used to construct the pad. 6.0 PERMITTING A Coastal Management Plan Questionnaire will need to be submitted.The proposed design can be finalized and constructed under the existing Army Corps of Engineers general permit GP96- 07.The size of the fill will be less than one acre and the length of access road will be less than PRELIMINARY DESIGN REPORT -DRAFT MARCH 2000 CITY OF LOWER KALSKAG BULK FUEL UPGRADES 10 D&M JoB No.37203-015-218 2,000 feet.The site was deliberately set at more than 300 feet from the river to meet the permit requirements. An NPDES permit may be required under recent changes to the regulations.

SITE VISIT 'On October 28 and 29,1999,Mr.Pat Butler of Dames and Moore conducted a site visit to Lower and Upper Kalskag.The purpose of the site visit was to gather information and community preferences on potential sites for the consolidated bulk fuel facilities,to determine the current fuel use and distribution,to evaluate the existing conditions,and to ascertain community preferences for the operation of the bulk fuel facilities. Existing Tank Farms:Currently there are several separate fuel farms located in and between the two villages. Lower Kalskag:The AVEC tank farm consisting of 12 vertical tanks is located next to the power plant. The City has a tank farm with two 30,000-gallon tanks,a 10,000-gallon tank,a 6,000-gallon tank,and other miscellaneous tanks.The City sells both fuel oil and gasoline.It also delivers fuel oil.The Elementary School has buried tanks,which were not inspected. Between the two villages is a retail farm owned by Fern Parent.She indicated she is no longer in the retail fuel business.The High School,located south of the runway,has two vertical tanks and a day tank. Offices Worldwide DAMES &MOORE%eal .A DAMES&MOORE GROUP COMPANY Alaska Department of Community and Regional Affairs November 22,1999 Page 2 Upper Kalskag:The City has two small fuel farms with a total capacity of 13,500 gallons.The Elementary School has four vertical tanks.Ken Morgan runs a retail fuel farm with a capacity of 36,000 gallons. Code Review:None of the farms appear to meet current code.Violations include no emergency vents, improper tank supports and improper separation distances.Most farms lack proper secondary containment.

Fern Parent 36,000 No longer sells fuel. Uses and Local Delivery:AVEC's fuel use is for the generation of power.The school uses diesel primarily for heating of the buildings.However,the total use listed above includes the capacity to produce standby power if needed.The school uses gasoline for buses and drivers education.The fuel use listed for Upper Kalskag is used for heat and vehicles.Ken Morgan's tanks are located near the Upper Kalskag City office.He currently fills 55-gallon drums supplied by the customer and then delivers the full drum to the customer.The fuel is transferred from the 55-gallon drum by a hand pump.The fuel farm in Lower Kalskag has dispensing pumps for both gasoline and heating oil for sales to the community. At this time,there is one fuel delivery truck within both villages and is operated by Lower Kalskag.It is a flat bed truck with a 500 gallon tank strapped to the bed.A small gasoline engine driven pump is used to dispense the fuel from the tank.This truck is used to supply the residential day tanks in Lower Kalskag.Upper Kalskag does not have a delivery vehicle at this time. Bulk Deliveries:Bulk fuel deliveries to the communities are by barge.AVEC and the school tanks in Lower Kalskag are filled from a barge header on the riverbank.The Lower Kalskag's farm appears to be filled by a hose from the barge.Lower Kalskag's fuel is delivered in the spring after the ice goes out on the river and then again in the fall just before freeze up.This technique supplies the villages with Dem(oe DAMES &MOOREBente4DAMES&MOORE GROUP COMPANY Alaska Department of Community and Regional Affairs November 22,1999 Page 3 sufficient fuel for the winter.Occasionally,Lower Kalskag has to buy approximately 10,000 gallons from AVEC to supplement the fuel supply until the spring barge.Since the current sforage capacity is 40,000 gallons,this indicates that 50,000 gallons is required to get the city through the winter.Upper Kalskag relies on the private farms for heating fuel and the storage capacity seems adequate. INFORMATION AND ASSUMPTIONS USED IN THE DESIGN The community preference is to locate a tank farm in each village.Additionally,each mayor expresses an interest in having the tank farm located away from the residential areas. The tank farm in Lower Kalskag will contain the City's tanks and the AVEC's tanks.The AVEC tanks will be reused,and space for 3 additional tanks of the same size will be allotted.The storage capacity of the City's tanks will be based on the total volume of fuel delivered by Yutana Barge Lines. The tank farm in Upper Kalskag will contain the storage for the school district and the City's tanks.The capacity of the City owned tanks would be increased to allow the City to become the retail outlet for Upper Kalskag.The two private farms would be decommissioned,which seems to be agreeable to the owners.The total storage capacity for the City would be the capacity of the existing city tanks and the __two private farms.This should provide enough storage for the community. Figures 1 and 3 show the proposed locations within each community.The sites for each community were developed based on the observations made during the site visit,the preferences expressed by the mayors, and the location of property lines.The property selected was based on information received from BLM and the Land Manager for the Kuskokwim Corporation.In general,the preferred site was a parcel owned by either the city or the native corporation.The tank farms were then set back from the property line 75 feet,which is the required set back for a dispensing tank.The dispenser was set back 25 feet,which is the required set back for a loading rack.These are the more conservative values and were used for the conceptual design. CONCEPTUAL DESIGN The design for each village will be similar.Figures 2 and 4 show the proposed layout for each village and the planned storage capacity.Within the main diked area,there will be two cells.The tank farm in Upper Kalskag will be divided into one cell for the city and the other for the school tanks.In Lower Kalskag, the tank farm will be divided with one cell for the city's tanks and the other for AVEC's tanks.Each farm would have a dispensing station.A loading rack may be included,but due to the small size of the one es DAMES &MOORE KeENeIUGE 4 DAMES &MOORE GROUP COMPANY Alaska Department of Community and Regional Affairs November 22,1999 Page 4 fuel tank truck it is not required.A high capacity dispenser,such as used for large trucks,could fulfill the need.Fuel to the school's 5,000 gallon tanks will have to be delivered by truck.Either-with a new truck purchased for this use or by the existing truck.The purchase of this truck will need to be decided in advance so that a loading rack can be included in the design. Lower Kalskag Sites:The site preferred by the Mayor of Lower Kalskag is Site 1,shown on Figure 1, and is located south of the town along the river.It is an undeveloped area and the aerial photo indicates that it is adequate.The advantages for this site are large size,no separation distance problems,a short barge header and the mayor prefers it.The disadvantage is no road to the site exists at this time.No elevation information specific to this site has been obtained at this time for evaluation of the flooding danger. The alternative,Site 2 on Figure 1,is near the existing sewage lagoon.The advantages are large site,no separation distance problems,and an existing road to the site.The disadvantage is a long barge header .will be required. The tank farm for Lower Kalskag will contain the tanks for AVEC.Fuel from the tank farm will be delivered by a pipeline to a 10,000-gallon double wall tank placed at the power plant.This volume should provide approximately one month supply of fuel. Both sites will require a long run of pipe to the power plant.A brief discussion with an engineer at AVEC indicated that a long run of pipe is preferable to hauling fuel by truck.The piping minimizes spills during transfers. Upper Kalskag Sites:Initially,the Mayor indicated a preference for a site that is 1.25 miles up river from the village.On discussing this with him,I indicated this would not be a good location due to the long distance from town.The road would add a substantial cost to the project which would not be acceptable since alternative sites are available.After further discussion,I suggested other alternatives, which are shown on Figure 3. There are three potential sites in Upper Kalskag.Site |is located near the airport.The advantage is that the aerial photography indicates that the soils may be more suitable than other sites based on it being heavily wooded.The disadvantage is the lack of an existing road. As shown on Figure 3,Sites 2 and 3 are on opposite sides of the road to the new housing project.The advantage for these sites is an existing road for access.The aerial photography indicates these sites may Ds.fm)DAMES &MOORE >BKSGTeWI A DAMES &MOORE GROUP COMPANY Alaska Department of Community and Regional Affairs November 22,1999 Page 5 have poorer soils than the other potential site,as it appears to be less vegetated with trees.However,the plans for the lagoon in this cleared area showed only 2 feet of excavation was needed. The tank farm will contain tanks for the city and the school.Since there are three separate school buildings,each one will be supplied with a 5,000-gallon double wall tank.None of the school buildings will be serviced by a pipeline. The idea of placing a set of tanks for the school in Lower Kalskag was considered.This would allow the elementary school in Lower Kalskag to be supplied by a pipeline.The high school is located between the two tank farm sites and would require an extra-long run of pipe.For this reason,a pipeline to it was not considered.For ease of accountability for the school fuel supply and a common barge fill point,it was decided to place all tanks at one location. RISKS TO THE TANK FARM Flooding of the tank farms is a concern.The USACE has set a recommended finished floor elevation of about 5 feet above the existing grade at the community building in Lower Kalskag.The danger from flooding is due mainly to ice jams in the springtime.The limited topography information indicates that all sites have the potential for flooding. The soils in the area appear to be discontinuous permafrost.However,this does not seem to be a design problem.This is based on the observation that the utilities for both villages are buried,which is usually only done in thaw stable or non-permafrost areas. CONCLUSION If one of the sites presented satisfy the community and DOE,then we will proceed with the completion of the 35%design report. Sincerely, DAMES &MOORE bed LiePatrickL.Butler,P.E.

Two sandbars in the Kuskokwim River near Kalskag were investigated for suitable embankment soils, and the existing Calista Corp.quarry site near the airport was visited and sampled as a potential source for the required aggregate surfacing materials. The descriptions contained in this report are based primarily on data obtained from the soil borings and laboratory test results.A test hole location plan,test hole logs and soils analysis sheets for gradation and classification accompany this report. A published DOT&PF report entitled "Kalskag Airport -Runway Extension and Materials sites _investigation -July 1973”also contain soils information on Kalskag Airport. LOCATION AND TRANSPORTATION The present site of the Kalskag Airport is located in Upper Kalskag,which is located on the north bank of the Kuskokwim River,3.2 kilometers upriver from Lower Kalskag.The Airport site lies approximately 45 kilometers west of Aniak,120 kilometers northeast of Bethel and 570 kilometers west of Anchorage. The Kuskokwim River affords easy accessibility by boat in summer and snowmachine in winter.Barges deliver cargo and bulk fuel during the summer.Upper and Lower Kalskag share a State-owned 2,200” gravel airstrip,and a road connects the two cities.Daily scheduled air services deliver passengers,mail and other cargo year-round. PROJECT SCOPE At the writing of this report the project will: "Extend 900 m runway to 975 m (1,119 m safety area),widen runway to 23 m and runway safety area to 36 m and resurface runway.Acquire land to accommodate runway extension. Replace runway lighting.Construct new road to tie into existing road on south side of runway. Abandon existing road section which crosses west end of runway.” FIELD METHODS The geotechnical field investigation was performed on June 7 through 12,1996 by Tom Ottley, Engineering Geologist and Tom Johnson,operator. A locally owned Komatsu PC-120 excavator was used to advance a total of 25 test pits to maximum depths of 5.2 meters,all within airport property.Six hand dug test pits were advanced along two existing gravel/sand bars located along the north bank of the Kuskokwim River in the vicinity of Upper and Lower Kalskag.The hand dug test pits ranged in depth between 0.5 m to 0.9 m. Approximately 55 field samples were taken and shipped to the Central Region Materials Laboratory. Laboratory analysis included testing for gradation,classification,moisture and organic content.Various samples taken from the two river bars and the existing Calista Corp.Quarry site were combined for "Quality”tests which included:1)L.A.Abrasion Loss,2)Sulfate Soundness and 3)degradation.All testing was completed in accordance with the State of Alaska,Unified and/or ASTM Test Methods. Laboratory summary sheets are attached. GENERAL GEOLOGY AND SITE CONDITIONS Kalskag is located in the Yukon-Kuskokwim Lowland physiographic province of Alaska.The village and airfield are built upon floodplain deposits of the Kuskokwim River.These deposits generally consist of mixed silt,sands and gravels with some intermixed wood,peat,and other vegetal matter. Numerous oxbow lakes and ponds occupy abandoned stream channels within the floodplain deposits. Floodplain deposits in the larger stream valleys normally contain numerous areas or masses of permafrost.This is confirmed for the Kalskag area by various water wells drilled at both village sites. The "Alaska Regional Profiles,Yukon Region"lists the area in the immediate vicinity of Kalskag as an area of discontinuous permafrost. To the depths tested perennially frozen ground was not encountered in any of the 31 test pits which were advanced during this field investigation.Perennially frozen soils were encountered during borrow excavation for the earlier extension of the runway and construction of the existing parking apron.The Public Health Service encountered perennially frozen soils while drilling for a new sub-division between Upper and Lower Kalskag. CLIMATOLOGY The village of Aniak lies 45 kilometers east of Upper Kalskag and is the closest community with climatological data.Aniak is located in the Transitional Climatic Zone of Alaska with intermediate characteristics to the Maritime and Continental Climatic Zones.The climatology is characterized by moderate diurnal and annual temperature variations.The following data was taken from the "Environmental Atlas of Alaska",by P.R.Johnson and C.W.Hartman,and while approximate,the data should be applicable to the area.- Mean Annual Temperature (C)-2 Mean Annual Precipitation (millimeters)500 Mean Annual Snowfall (millimeters)1510 Thawing Index (degree days)2500 Freezing Index (degree days)4000 Design Freezing Index (degree days -1 year in 10)5000 It should be noted that although the mean annual precipitation totals only 500 mm per year,the average total for the four (4)month period,June through September,is 305 mm.This data was taken from the U.S.Government Publication no.86-43,"Climatology of the United States."

GEOTECHNICAL INVESTIGATION 1.Existing Airport -A total of 25 test pits (see T.P.'s 1-96 through 25-96)were advanced within existing airport property during the June 1996 field investigation.Eight test pits (T.P.'s 17-96 through 24-96)dug along the side of the existing runway found 0.1 m to 0.2 m of a gravelly sand surface course.Foundation materials consisted of 0.5 m to 0.8 m of organic silt over 1.3 m to 3.0 m of sandy silt.The sandy silt was underlain by sandy gravel/gravelly sand which extended to the bottom of the' test pits from depths of 4.0 m to 5.2 m.The organic silt had moisture contents ranging from 43.5 to 69.3 percent and organic contents ranging from 6.4 to 14.9 percent.Two samples of the sandy gravel/gravelly sand had a P0.075 of 1 and 10.A water table was found below the west end of the runway between depths of 3.6 m and 3.7 m. Five test pits (T.P.'s 12-96 through 16-96)were dug off of the west end of the existing runway for the proposed runway extension.These test pits found 0.1 m to 0.2 m of surface organics over 0.2 m to 0.5 m of organic silt.Foundation materials consisted of 1.3 m to 2.2 m of sandy silt over silty sand and gravelly sand.Two of the test pits bottomed in silty sand at depths of 4.5 m while three of the test pits bottomed in gravelly sand at depths from 3.8 m to 4.0 m.The sandy silt had a PO.075 ranging from 38 to 90 and a moisture content ranging from 7.3 to 44.5 percent while the silty sand had a PO.075 ranging from 7 to 22 and moisture contents of 10.0 and 11.7 percent.A sample of the gravelly sand had a P0.075 of 6.A water table was found between depths of 3.5 m and 3.6 m. A total of 10 test pits (T.P.'s 1-96,and 3-96 through 11-96)were dug for the proposed new access road off the south side of the existing runway between Stations 1+250 and Station 1+950,from 100 m to 135 m right of the existing runway centerline.These test pits found 0.1 m to 0.2 m of surface organics over 0.2 m to 0.8 m of organic silt.Foundation materials consisted of 1 m to 3 m of sandy silt over sand and sandy gravel.Two of the test pits bottomed in sand at depths from 3.5 to 4.0 m while the rest of the test pits bottomed in sandy gravel at depths from 4.8 mto 5.2 m.The sandy silt had a P0.075 ranging from 66 to 80 and a moisture content ranging from 10.9 to 38.9 percent while a sample of the sand had a PO.075 of 3 and a moisture content of 5.7 percent.Samples of the sandy gravel had a P0.075 ranging from 1 to 3.A water table was found at Sta.1+450 at a depth of 4.7 m.A test pit (T.P.3-96)dug for the new access road off the east end of the runway found 0.3 m of organic silt over 3.3 m of sandy silt underlain by sandy gravel.A sample of the sandy silt had a PO.075 of 78 and a moisture content of 30.1 percent.A sample of the sandy gravel had a PO.075 of 0.A water table was found at a depth of 4.3 m. 2.Kuskokwim River Bars - Two potential gravel sources were also explored.The first site is an existing gravel bar along the north side of the Kuskokwim River approximately 0.4 km upstream from Upper Kalskag (see T.P.'s 26-96 through 28-96).The gravel bar varied between 610 m and 915 m in length by 15 m to 60 m wide.Thethreetestpitsdugonthisbarfoundsandygravelandgravellysandwithanestimated5percentof cobbles up to 150 mm in diameter with the rest of the material less than 37.5 mm in diameter.The sandy gravel/gravelly sand had P0.075 values of 1,0 and 5.A combined sample was tested and found to have an LA Abrasion value of 15 and a Degradation value of 69.The water level in the gravel bar at the time of the investigation was found between depths of 0.3 m and 0.5 m but this will fluctuate in accordance with the level of the water in the Kuskokwim River. The second site is an existing gravel bar along the north side of the Kuskokwim River adjacent to Lower Kalskag (see T.P.'s 29-96 through 31-96).This gravel bar varied between 760 m and 915 min length by 90 m to 180 m wide.The three test pits dug on this bar found sandy gravel with an estimated 5 percent of cobbles up to 125 mm in diameter with the rest of the material less than 37.5 mm in diameter.All three samples of the sandy gravel had a P0.075 of 1.A combined sample was tested and found to have an LA Abrasion value of 15 and a Degradation value of 77.The water level in the gravel 4 bar at the time of the investigation was found between depths of 0.5 m and .9 m but this will fluctuate in accordance with the level of the water in the Kuskokwim River. 3.Calista Corp.Quarry Site - An existing quarry rock source was also visited as a potential source for crushed aggregate materials. The site is an existing quarry located approximately 2.4 km north of Upper Kalskag.This quarry is owned by Calista Corp.and is currently being mined for both pit run and crushed rock.The rock at this site is currently being ripped.Harder material is reported at the quarry and may require drilling and shooting.The quarry shows a highly fractured and jointed igneous intrusive rock with weak very weathered zones.A sample of the more competent rock had an LA Abrasion value of 16 and a Degradation value of 33 while a sample of the weak very weathered rock had an LA Abrasion value of 18 and a Degradation value of 1.Two samples taken from an existing stockpile of crushed rock both had a PO.075 of 4.

AND AVCP PREPARED BY HOWARD GREY &ASSOCIATES,INC. GEOLOGISTS &ENGINEERS ANCHORAGE,ALASKA January,1982 APPENDIX "A” LOWER KALSKAG PRELIMINARY SOILS-FOUNDATION EXPLORATION Between November 3 and 5,and November 17,1981,a soils exploration was conducted by representatives of Howard Grey &Associates,Inc.at Lower Kalskag, Alaska.The purpose of our exploration was to examine subsurface conditions and provide foundation design recommendations for 19 proposed AVCP housing lots. Lower Kalskag is located along the west bank of the Kuskokwim River,approximately 62 miles northeast of Bethel and 350 miles west of Anchorage. Field work at Lower Kalskag consisted of 2 test pits excavated by a Case 580 "Construction King"backhoe and 13 soil probes.Soil densities and temperatures were noted at various depths in the backhoe excavations.The results of these observations were shown on the boring logs.Backhoe pits were logged in the field and representative samples were retained for later comparative laboratory analysis. Lower Kalskag is located on a flood plain of the Kuskokwim River.The proposed building sites are situated northeast of the town site immediately north of an oxbow lake.The new housing lots are level with little topographic relief.With the exception of the slight depression between Lots 4 and 5 in the north block, the housing subdivision appears to be fairly well drained. Vegetation is similar across the entire new subdivision and consists of scattered tall birch and spruce trees intermixed with dense growths of high brush and grasses =----y (Photos No.1 and No.2). According to data provided by the Army Corps of Engineers,the entire townsite, including the new subdivision,will be inundated by a flood with a frequency of 100 years.However,in lower portions of the community,flooding should be expected to occur more often,particularly during spring runoff.A summary of flood data for Lower Kalskag is provided on the community map published by the State of Alaska Department of Community Affairs. Subsurface soils conditions are basically similar across the entire subdivision. These consist of some 12 inches of organics and organic silt underlain by a thick silt to fine silty sand deposit.At the time of our exploration,the uppermost 6 inches or so were frozen.The organics and organic silt beneath seasonal frost was moist and soft.Brown,moist silt underlies the organics.The upper 2 feet of the silts contains some organics. The silt is 11 feet thick in LK-1 and greater than 12 feet in LK-2.Some minor amounts of fine.sands are associated with the silts. A fine gray silty-sand was encountered in LK-I near the base of the excavation. In test pit LK-1,water was encountered at about 13 feet,but no water was observed in LK-2.Groundwater levels may be higher during spring and summer months.A soil probe at Lot No.10 in the south block indicated higher soils moisture than was observed in the other lots. A thin zone of relict permafrost was encountered at 13 feet in test pit LK-2. The frozen zone did not appear to cover the entire excavation and no visible ice was observed.Thirteen additional probes were made throughout the remainder of the subdivision and no shallow permafrost was identified.However,the nrobes were only extended to a depth of 6 feet. Soil samples obtained from the field reconnaissance were returned to our laboratory to confirm field classifications.Analysis included moisture con- tent,sieve analysis,and Atterberg Limits.Results of these various tests were appended to this report.Also included is a particle size distribution curve of gravel retrieved from along the river at the boat landing area. Recommendations: The 19 AVCP housing units are located on dry wooded lots underlain by firm to stiff silts.The silts are rated F-4,or highly frost susceptible,so the soils and any foundations constructed on them will be subject to seasonal move- ment.During the winter the soils will heave upon freezing,and during the summer the soils will settle upon thawing.Frost heaving and thaw consolidation do not generally occur uniformly,but instead take place as differential move- ment.The degree of movement should not be severe due to the low moisture con- tent of the soils.However,soil moisture and integrity of the silts may vary either naturally or due to construction activity. To avoid large scale differential movement,an extensive,costly foundation such as deep piles or thick fill sections composed of non-frost susceptible materials would be required.As an alternative,foundation designs could anticipate some seasonal movements with provision for adjustments by shimming or leveling to be performed as necessary. This proposed alternative design consists of a subsurface gravel mat supporting an on-grade pad and post foundation.This system is suqgested due to avail- ability of non-frost susceptible materials,ease of construction using backhoe or similar types of available construction equipment,and economy. Backfill used in the building pad would consist of alluvial gravels obtained from designated borrow areas along the Kuskokwim River.Oral communication with city officials indicated that gravel is available from the opposite side of the river. Material sampled from the shore is a sandy gravel with only a small percentage passing the number 200 sieve (See Appendix).The sample analyzed is non-frost susceptible (NFS).Similar sandy-gravel was used in previous roadway construction throughout Upper and Lower Kalskag. Installation of the foundation should be performed as follows:(1)Excavation of soft organics and upper-soils to firm underlying soils.In most cases this will require a minimum excavation of some 3 feet.However,a deeper fill section of 4 to 5 feet is desirable and will provide greater resistance to seasonal move- ments.The dimensions of the base of this excavation should exceed the dimensions of the foundation pad or sill.(2)Backfill with NFS sandy-gravel in 12 inch lifts with each lift being compacted to 90%AASHTO standard (T-99)density.Mound the gravel above the surface elevation at least 1]foot to provide additional drainage .(4)Cover the foundation mat with an impermeable layer,i.e.a thin layer of silt,to inhibit water movement into the gravel prism.Either individual pads or continuous sills can be constructed on the gravel mats.It is recommended 'that a bearing capacity of 2000 lbs.per square foot (psf)be used for these soils. An example of this foundation alternative is illustrated in Figure No.3. It is recommended that certain precautions be taken during construction of the foundations including:limiting the use of tracked or wheeled vehicles around or near the foundation areas as excessive passes may disturb and soften the in-situ soils,particularly if wet;placement of filter type fabric between the gravel backfill and in-situ soils if soils are found to be wet or disturbed during ex- cavation;provision for drainage away from the foundation and building sites.In the event of high precipitation or surface runoff,provision should be made for pumping or other means to provide dry foundation excavations.Roof drainage should be diverted away from the foundation area;an airspace of at least 2 feet between the building and ground surface should be provided in case any relict permafrost exists.This will also assist somewhat in elevating the house from potential flooding. : The recommedations of this report are based on the assumption that soil conditions do not deviate from those disclosed in the test excavations (or borings,which ever description applies).The owner should understand that the foundation alternatives discussed are based in part on economic considerations and will only minimize differential movement.It is anticipated that periodic shimming or leveling of the foundation will be required unless some form of piling system is utilized. If any variations or undesirable conditions are encountered during construction, or if the proposed construction will differ from that planned at the present time,we should be notified so that supplemental recommendations can be given.
