A site visit was conducted by Chris Riggio,P.E.(Riggio Engineering)during May 30 - June 1,1999 to collect site information,interview key personnel,and look at possible sites for the tank farm upgrade.Video and photograph documentation of the existing tank farm (hereafter referred to as Tank Farm B)and proposed sites were collected during the site visit.Tank Farm B is located near the dock and adjacent to a diesel-powered generator module (which supplies electricity to the community)and to a new boat storage and maintenance facility (please refer to site drawings and maps).Tank Farm A will be located near Tank Farm B as shown in the attached site drawings.Five of the seven tanks currently located at the Tank Farm B site will be moved into containment cells at Tank Farm A.The remaining two tanks at Tank Farm B will be moved aside while a containment cell is constructed,then moved back into place adjacent to the generator module.Tank Farms A and B will collectively become the upgraded tank farm system. On Thurday June 3%,1999,a conference call to discuss the said project was conducted. This call included Butch Gundersen,Mark McNeley,and Justine Gundersen of Nelson Lagoon,Percy Frisby with the State of Alaska's Division of Energy,and Matt Carr with EPA,and Chris Riggio with Riggio Engineering.Based upon this conference call,the highest priority for the project was to complete a design package for the tank farm upgrade,then submit this package to the appropriate entities to obtain project funding. Once the design package was complete,the second priority would be to complete an SPCC plan for both tank farms.The goal of the community of Nelson Lagoon is to obtain funding,obtain system upgrade materials,and complete construction of the tank farm upgrade at the soonest possible date. Tank Farm B currently consists of seven 20,000-gallon horizontal double-walled aboveground storage tanks.The tank farm is not currently situated within a diked and lined containment cell.Three of the tanks are connected to the diesel generator which supplies electricity to the community;these three tanks are plumbed to the generators via double-walled underground piping. The seven tanks are cradled by coated steel frames and each tank frame has three support feet.It appears that all of the tanks contain penetrations for the installation of automatic tank gauging and interstitial monitoring system sensors;these penetrations are all sealed by screw in fittings and are located on the top of the tank.In addition,the tanks may also contain penetrations for high (95%)and high-high (98%)level alarm and shutoff systems,but this assumption was not confirmed as no specific documentation was available for the tanks. The tanks are used by the community of Nelson Lagoon to supply fuel to aircraft,motor vehicles,facility and home heating systems,and the diesel-fired generators.The following table summarizes tank information: TANK TYPE SIZE (gallons PRODUCT 1 Single cell 20,000 Diesel #2 2 Single cell 20,000 Diesel #2 3 Single cell 20,000 Heating Oil (Diesel #1) 4 Single cell 20,000 Heating Oil (Diesel #1) 5 Single cell 20,000 Unleaded 6 Double cell 10,000 /10,000 Heating Oil (Diesel #1)/ Unleaded 7 Triple cell 6,667 /6,667 /6,667 |AVGAS/AVGAS/Unleaded Please note that the 6"and 7"tanks are compartmental tanks.Each compartment is completely separate from the others,with separate fill &vent pipes,manways,etc. Total product capacities for the tank farm are as follows: PRODUCT CAPACITY (gallons) Diesel #2 40,000 Heating Oil (Diesel #1)50,000 Unleaded gasoline 36,666 AVGAS 13,334 TOTAL CAPACITY:140,000 This design package contains written design specifications as well as site drawings and maps,engineering calculations,liner specifications,fencing estimates and rough order of magnitude cost estimates for the Nelson Lagoon tank farm upgrade project.This package was reviewed by Michael Brubaker (A/PIA)on June 17,1999 and final comments were incorporated by Chris Riggio (Riggio Engineering)June 18-21,1999. DESIGN SPECIFICATIONS AST Tank Farm Containment Cell -Design Specifications Aboveground Storage Tank Farm Nelson Lagoon,Alaska Design Specifications June 21,1999 Prepared By: Christopher M.Riggio,PE Riggio Engineering P.O.Box 244231 Anchorage,AK 99524 (907)245-1967 These design specifications are intended to be used in conjunction with design drawings for Tank Farm A (the aboveground storage tank (AST)farm)at Nelson Lagoon,Alaska. Tank Farm A will consist of five 20,000-gallon ASTs.This same design may be used to upgrade Tank Farm B for the remaining two 20,000-gallon diesel fuel storage tanks that support the community's electricity generator system;the attached drawings also include a design for this upgrade.Note that the two tank farms require different sizes and types of liner (due to containment cell dimensions and types of product stored),Also note that vendor estimates for containment cell liners may vary slightly with actual order costs due to (1)slight difference in actual design size (refer to specifications),and (2)vendor may give a better price for an actual order. Assumptions e No subsurface investigation of underlying soils at the Tank Farm A site has been accomplished,so actual soil composition is unknown.Underlying soil composition is believed to be gravelly sand material as encountered below the top organic layer at several sites in the vicinity;this information was relayed to the Engineer by the facility owners.In addition,the exact depth to groundwater for this site is unknown, though it is estimated to be greater than four feet below ground surface,based upon historical data.Due to the presence of well-drained gravelly sand soils,some tidal influence on groundwater depth is expected to occur.Without actual soil composition and groundwater depth information,some minor settlement of the Tank Farm A foundation may occur,even if the foundation is installed in accordance with these specifications.Some settlement is considered acceptable for this site since the foundation is not being used for a building where settlement might not be considered acceptable. e The Engineer recommends that the facility owners excavate one or more test pits at the Tank FarmA site to verify (1)that depth of groundwater is more than four feet below ground surface,and (2)that soil material is generally homogenous and that there are no layers of clay or silt below the Tank Farm A foundation site.The test pits should not be excavated within the bounds of the containment cells.However, test pits should be excavated as close as possible to the planned bermed containment cell area to give a good indication of what soils lie below grade.The maximum (highest)level of groundwater should be determined.Excavate test pits during a period of high tide and,if possible,during a period of or shortly after heavy rains,as practical,since the objective is to determine the highest water table level.Verify that 1 AST Tank Farm Containment Cell -Design Specifications the groundwater table level is at least four feet below grade.Soil should be re- compacted in loose 12-inch lifts as it 1s returned to the test pits. Based upon visual classification,the soil is assumed to be poorly graded gravelly sand with little fines.For calculations of bearing capacity of the compacted soil,the friction angle of the soil is assumed to be 35 degrees,within the typical range of 26 to 46 degrees (Principles ofFoundation Engineering,PWS Engineering Publications, 1984).In addition,the maximum Proctor dry density of the soil to be used for the tank farm foundation is assumed to be 130 pef (pounds per cubic foot);130 pcf lies within the typical range of 130 and 145 pef poorly graded gravelly sand with little fines.These numbers are used in the engineering calculations (see attached)to design a tank farm foundation. Prior to construction,the Engineer recommends the facility owner send an adequate soil sample to a soil testing laboratory in Anchorage to conduct a sieve analysis and a Proctor test;send a sample of soil representative of those materials which will be used for the containment cell foundation.Typical costs are: e Sieve analysis:approximately $100 e Proctor Test:approximately $200Thetestswilldetermineexactclassification and maximum Proctor dry density of the material.Based upon this information,the Engineer can review these results and confirm that actual materials to be used for the construction of the tank farm foundation will be adequate to meet the requirements of these specifications. Site Selection The proposed site for Tank Farm A is within 100 yards of Tank Farm B,as shown in the attached drawings. This Tank Farm A site was selected for the following reasons: 1.Siteis located close to the main road for easy vehicle access.2.Siteis located away from frequently used structures to minimize vapor and fire hazards to personnel and facilities. 3.Site is within reach of refilling hoses that are used by fuel delivery barges and/or ships to fill the tanks.The dockis located nearby,as shownin the attacheddrawings. 4.Site has good natural drainage and is located higher than those areas susceptible to flooding during storms. Site Preparation Stake out an area for Tank Farm A as shown in the attached drawings and that best uses the natural topography of the land to minimize the need for large quantities of excavation and filling during containment cell and surface drainage construction. Refer to attached drawings for containment cell design dimensions. Recommend facility owner complete construction and grading of access road and re- fueling pad prior to constructing the containment cells,for ease of access for heavy equipment. Temporary access roads may also need to be installed on the east and west sides of the containment cell area for vehicles to move the tanks into the cells. AST Tank Farm Containment Cell -Design Specifications After staking out the area to be cleared for the Tank Farm A cell and after construction of access road,refueling pad,etc.,remove organic grasses,peat,silty or clayey soils,and other overburden organic materials and excavate to sand and gravel. Recommend use of beach material (gravelly sands)for fill,selecting material that is well-graded,as practical,and free of organic matter,wood,debris,or other deleterious material.Fill material for tank farm foundation shall be free of vegetation,organic matter,cinders,and any material that will result in poor compaction and uneven settling of the foundation. The foundation for the tank farm shall be level.The final grade shall be at least one (1)foot above the surrounding ground surface to provide suitable drainage and to compensate for minor settlement that might occur (refer to attached drawings). The dimensions of the tank farm area shall be at least 97 feet by 82.5 feet.This includes the entire cell dimensions (82 feet by 67.5 feet),plus 5 feet around the entire cell footprint (for the liner edge cover)and an additional 2.5 feet beyond the liner edge (to maintain some distance around the liner cover edge).Some minor variation to these dimensions is acceptable since the liner has been sized with a little extra at each side to account for such minor unforeseen construction variances.In addition, the berm walls may require a slightly wider foundation depending upon how well the selected material stacks.However,ensure the cell volume is not decreased. Drainage Within Containment Cell Within the containment cell footprint,materials shall be graded with a 1-inch for every 10-foot grade,sloping downwards towards the sump drains. Refer to attached drawings for gradient directions. Foundation Construction and Material Compaction Use beach material (gravelly sands)for the cell foundation,selecting material that is well-graded,as practical,and free of organic matter,wood,debris,or other deleterious material. Fill material shall contain less than 10%fines (material passing a No.200 sieve). Screen soils in the field,as necessary,to meet these requirements. Remove from fill all large cobbles or boulders with dimensions in excess of 8 inches. Materials shall be placed in loose 10”to 12”lifts and compacted to a minimum of 95%of maximum Proctor dry density (from the American Standard for Testing of Materials [ASTM],procedure D-1557). Ensure containment cell surface is firm and level prior to the placement of tank foundations. Berm Construction and Liner Installation Use beach material (gravelly sand)for the berms and for cover material,selecting material that is well-graded,as practical,and free of organic matter,wood,debris,and other deleterious material. Construct three of the five berms so that tanks can be easily moved onto the pad once the liner is installed and covered.Leave the easternmost and westernmost berm ends (the fourth and fifth berm walls)of the cell unconstructed until tanks are installed within the containment cell. AST Tank Farm Containment Cell -Design Specifications e Ensure the top of each berm is at the same elevation such that containment area is at least three feet deep from the top surface of the containment cell floor to the top of the berm (refer to attached drawings).Make any and all adjustments to berms before the liner is installed.Note that the berm walls will be slightly higher along one corner of the cell than the other due to the slight grade of the floor of the cell to encourage drainage towards the sump drains. e Provide one 115'X 95'Cooley reinforced flexible membrane liner (or equivalent), which is compatible with fuel products stored in tanks.See attached liner specifications.Obtain manufacturer's installation instructions. e Prior to laying liner down,carefully check bed to ensure no sharp objects (sticks, metal,sharp rocks,nails,etc.)are present.This task is vital to protecting the liner and to preventing puncturing due to the addition of the weight of the tanks. e A layer of geo-fabric may be installed prior to liner installation to protect the bottom of the liner from puncturing.This layer is recommended.The geo-fabric layer to be installed on top of the liner is more critical for this application and is strongly recommended. e Install liner on a day with low winds to ease task completion.Install liner in accordance with the manufacturer's installation instructions. e Exercise care during handling to ensure liner is not punctured or damaged by equipment,tools,rocks,or other sharp objects. e Install geo-fabric cover over top of liner before laying down cover material.Overlap sections as necessary to ensure no areas of the liner are left uncovered.Install protective geo-fabric in accordance with manufacturer's specifications. e Carefully inspect cover material (gravelly sand)before covering liner to ensure there are no sharp objects present (sticks,metal,sharp rocks,nails,etc.)which could puncture the liner. e Place cover material in loose 6”lifts and compact to at least 95%of maximum Proctor dry density within the cell.Provide adequate material so that compacted depth is 6” above the top of liner and geo-fabric. e Lightly compact cover material over the cell liner in areas where the fourth and fifth berms will be constructed and where the extra liner material lies beyond the containment cell footprint.Compact cover material to density that is firm enough to drive vehicles onto temporarily to install concrete pads and tanks into cells without damaging the liner. e Once material covering the liner has been compacted,measure out proper locations for the concrete pads.Note that the 3'X 4'X 6”deep concrete pads previously fabricated by the facility owner may be used on/y for the tank frame supports at the end of the tank frame where there are two supports and only if they have been constructed to support design loads.On the other end of the tank frame,where only one support is present,a 4'X 4'X 6”deep concrete pad must be used.Refer to engineering calculations for detailed analysis of requirements for dimensions of concrete pads.Please note that the 3'X 4'X 6”deep concrete pads were determined to be inadequate for maximum design loading for this foundation material for all tank frame supports. e The 3'X 4'X 6”deep concrete pads previously constructed may be used in lieu of 4' X 4'X 6”deep pads only if laboratory soil testing yields a higher maximum Proctor 4 AST Tank Farm Containment Cell -Design Specifications dry density and friction angle than those assumed and only ifthey are evaluated based upon anticipated design loads.These engineering calculations will need to be re- evaluated based upon laboratory soil test findings to confirm that they may be used for supporting the single support leg side of the tank.In addition,a higher value of material compaction than 130 pcf would need to be achieved in the field;the new higher value would depend upon the results of the Proctor test. ¢In advance of this construction work,pour and cure 7 (seven)4'X 4'X 6”deep concrete pads.Concrete shall be adequately mixed and cured to provide a minimum compressive strength of 3000 psi.Recommended slump for concrete mix shall be 1” minimum and 3”maximum.Use steel grade 60 (or equivalent)size #4 rebar for reinforcement of concrete slabs.Place rebar such that a minimum of 1”of concrete cover remains between the bottom of the concrete pad and the edge of the rebar. Construct concrete pads in accordance with design drawings (see attached). e Place concrete pads. e Check concrete pads for levelness and adjust as necessary.For each tank,ensure the three pads are level between each other. e Place steel plates over concrete pads. Add additional materials to cells to bring cell floor to a height slightly (1 inch)higher than top of concrete pads to ease in tank installations.Compact additional material to 95%of maximum Proctor dry density (ASTM D-1557).Provide adequate material so that total depth of cover over liner and within cell is a compacted depth of 13”. ¢Install tanks on concrete pads and in cells.Recommend installing tanks by type in locations as shown in the attached drawings (e.g.heating fuel tanks are grouped in Cell 1,and the gasoline and AVGAS tanks are grouped in Cell 2). e Once all tanks have been installed within the containment cells,carefully remove temporary liner cover material at the location of the fourth and fifth yet-to-be constructed berms,taking care to not damage the liner. e Roll the remaining liner back up into the containment cell in order to construct the fourth and fifth (final two)berms. e Ifacontainment sump drain is chosen,install drain and piping prior to construction of the fourth and fifth berms (see containment cell sump discussion,below). e Following construction of the final berms (fourth and fifth),complete liner installation and cover with appropriate material (as described previously). e On outside of berm,cover the extra liner material with a minimum of 8”of cover material.Liner dimensions were selected to include a little extra material to accountforslightvariancesincelldimensionsandcellbermheights.A minimum of 5 feet of liner is specified for the edge of the liner outside the bermed area (see drawings).If more than 5 feet of excess liner remain,the installer may cut off the excess,fold it under,or lay it flat.If the excess lies flat,ensure it is completely covered to prevent the possibility of winds catching an uncovered edge. ¢Cover liner on berms with a minimum of 6”of cover material. Containment Cell Sump e Two containment cell sump systems are discussed here: AST Tank Farm Containment Cell -Design Specifications 1.Install a drain at the low corner of each cell.In this case,no perforation of the cell liner is required -drain is used as a low point within the cell from which accumulated water can be pumped.Recommend installation of a drain that is screened through the depth of cover material overlying the liner,as shown in the attached drawings,and can be opened on the top to insert a hose for water __ removal.Size screen such that mesh is of a size that will prevent material from passing through screen into the drain.Use a properly sized pump with appropriate hoses to empty cells of accumulated water,making sure that total accumulation in cell does not exceed 8”(eight inches)at any time;or: 2.Install a drain at the low corer of each cell,perforate containment liner with piping,seal liner around piping penetration,and install a drain valve external to the cell that can be opened to release accumulated water.Drainage piping shall be installed during cell construction and shall lie beneath the berm wall and containment cell foundation.Drain valve shall be external to the containment cells and berm walls.Please refer to the attached drawings for sump details. e For both systems,note that accumulated water shall not be released to the environment if there is any presence of an oily sheen,or there has been any petroleum spilled within the containment cell. e AJl accumulated water shall be inspected for the presence of petroleum product or oily sheen prior to pumping or draining from the containment cell.If petroleum product or oily sheen is present,the water shall be collected and properly disposed. All collected oily water shall be properly contained in accordance with applicable regulations,properly labeled and numbered,and safely stored.A list of all containers shall be maintained at the Fuel Administrator's office in Nelson Lagoon.All related activities shall be conducted in accordance with the requirements of applicable regulations and an approved SPCC (Spill Prevention Countermeasure and Control) Plan.One option for disposal of oily water is treatment through an ADEC (Alaska Department of Environmental Conservation)approved oil/water separator system prior to discharge. e Ifany release has occurred or if a sheen is present on the accumulated water,the tank farm system owner shall take immediate steps to meet regulatory requirements in accordance with federal,state,and local regulations regarding notifications,cleanup, and system repairs. e Accumulated water (from rain,melting snow,etc.)shall be routinely drained from the containment cells and in accordance with the aforementioned requirements.Water accumulation shall not exceed 8”(eight inches)in depth at any point within the cell nor at any time.Drain accumulated water on a regular basis so that accumulation is minor to allow for maximum cell capacity at all times. e Ifasump drain is installed in the cells,insure liner is completely and properly sealed around the liner penetration to prevent any possible compromise of system integrity. An improper seal would jeopardize the entire containment system and would result in non-compliance of the tank farm.Sump drain shall be installed such that bottom edge of actual drain grill is flush against the top side of the liner.This feature,along with slight grade within the cell,will ensure all water is drained from the cell when draining event occurs. AST Tank Farm Containment Cell -Design Specifications Ensure that the drain valve is installed on the exterior of the cell and is kept in the closed position at all times except for when accumulated water is drained from the cell by a properly trained individual.Maintain a lock and chain on the external drain valve.Make sure that water is routinely drained from the piping and valves to prevent freezing and cracking. Site Drainage The immediate area surrounding the AST tank farm shall be adequately graded to prevent runoff flow of water from the surrounding small mounds (approximately 5 to 15 feet above the Tank Farm B area)into the containment cell or along the berm edges.A shallow drainage ditch around the perimeter of the tank farm is recommended.Construct drainage ditch such that closest edge is a minimum of five (5)feet from the edge of the liner to prevent sloughing of material covering the liner. Construct walls of drainage ditch no steeper than a 1:3 (vertical:horizontal)slope. Slope drainage ditches towards the road (on the south side of the Tank Farm A tank farm site). Provide adequate culverts or additional drainage ditches to insure no ponding of runoff water around the tank farm occurs.No additional drainage is necessary if ground permeability is determined to be acceptable to prevent ponding. Recommend constructing drainage ditches after installation of the containment cells and tanks to account for any construction variances. System Piping Install all system piping aboveground (this does not apply to sump drain piping which will be installed below ground).Install piping with adequate flexibility (e.g.use of elbows and bends in piping runs)to protect against stress or rupture at joints due to seismic activity,ground settling,or other occurrences. Welded piping is strongly recommended over threaded. Coat piping with corrosion prevention paint. Pressure test all piping in accordance with system standards and prior to use. Install bollards,as needed,in areas where piping run is susceptible to impact by vehicles or equipment. Fencing and Site Security e Provide adequate fencing for site security.Fencing is a regulatory requirement and can help prevent the inadvertent release of product by children,vandalism, unauthorized persons,or animals.Even though vandalism has not been a problem in the small community of Nelson Lagoon in the past,a form of site security is still required to secure the tank farm. Recommend using a six-(6)to eight-(8)foot chain link fence with an access gate that can be locked. Install fencing such that fence posts do not interfere with containment cell liner. See attached drawings for suggested fencing location. AST Tank Farm Containment Cell -Design Specifications Lighting e Provide adequate lighting to allow for tank operation and inspection activities to occur at any time of the day or night.Lighting is important so that workers can see their way around the facility and to discourage intruders. e Lights should provide adequate illumination and be in good working order. ¢Recommend using automatic light sensors to activate lights,thus saving electricity during periods of daylight.This is preferable to timer systems because of the extreme Alaskan daylight fluctuations.. e See attached drawings for suggested light pole locations. Tank Anchoring e Install tank anchor straps between tanks and in accordance with tank specifications. e Install tank anchors so that buried portion of anchor is outside of cell liner footprint. Ensure that cell liner is not penetrated during tank anchor installation. e Install tank anchors at the maximum depth recommended by manufacturer's instructions.Since Nelson Lagoon is in a seismically active area,proper tank anchoring is strongly recommended to prevent the possibility of tank or pipeline spillage of product. Maintenance e The containment cells,including the berms,sump drain,and foundation surface,shall be fully inspected on at least a weekly basis.Daily routine checks are strongly recommended to look for water accumulation in the cells,leaks or spills,or any related system problems.Ensure liner is kept covered by specified overburden of material.Over the course of time,loss of material will likely result from wind,rain, and other erosive actions.Add material to cell berms,containment area,and edge-of- liner anchor on an as-needed basis to protect the cover from ultraviolet degradation, puncture by personnel use and equipment,and from being lifted up and damaged by wind action. e Keep the containment cell area clear of debris,unnecessary items,snow,and standing water.Prevent grasses or other vegetation from growing in or on the containment. Manually remove vegetation or use an herbicide.Recommend use of environmentally friendly herbicides to avoid possible soil or water contamination scenarios in the future.Ensure any herbicide or chemical used is compatible with the liner material and will not result in liner degradation. e The specified liner is designed to be resistant to plant and grass roots,so growth of grasses on the outside walls of the containment berm is acceptable and may help prevent some erosion of the cover material.Growth of plants and grasses within the containment cell is not recommended. e Iftears in the liner are noticed,repair them immediately. Piping Maintenance e System piping must be maintained in sound condition. e Follow manufacturer's instructions or industry standards for maintaining valves and corrosion protection devices. AST Tank Farm Containment Cell -Design Specifications Repair and repaint pipes to protect the pipe when coating or paint is wearing through or chipping. Repair pipes as soon as possible after problems are noted. Replace threaded pipe with welded pipe whenever possible. Make sure signs on piping are visible and legible (product,maximum pressure,flow direction,and warning). Protect piping from vehicle traffic as much as possible (through piping location and use of protective bollards). Recommended System Improvements Recommend facility owner contact Spokane Industries (Tank Manufacturer)to order Operation &Maintenance Manuals and tank system drawings.Maintain these documents at the Fuel Administrator's Office in Nelson Lagoon. Recommend installation of automatic tank gauging and interstitial monitoring systems (Veeder-Root or equivalent).Also recommend installation of high-level alarm (at 95%full)and high-high level automatic shutoff (at 98%full)in all tanks. During the Engineer's site visit May 30 to June 1,it was noted that some system appurtenances related to automatic tank gauging and interstitial monitoring are ready installed in some of the tanks,but are not currently in use. Develop an SPCC Plan for the facility. References 1. 2. 3. 11. Das,Braja M.,Principles of Foundation Engineering,PWS Engineering,Boston, MA.,1984.

However,when designed for soft or wet subgrade conditions,native vegetation,roots,and topsoil may be left in place so as to limit disturbance and resulting shear strength loss of the subgrade soil. JUN.-02'99(WED)15:51 POLAR SUPPLY CO.INC.TEL:907 562 7001 P.006 Geotextile Placement:The geotextile shall be unrolled as smoothly as possible on the prepared subgrade in the direction of construction traffic.Geotextile rolls shall be overlapped in the direction of subbase placement.The geotextile shall be overlapped or seamed in accordance with the minimum requirements provided in Table 5-3.Sewing is recommended where subgrade soils exhibit a CBR less than 0.5 and is preferred where subgrade soils exhibit a CBR greater than 0.5 but less than or equal to 1. If required,the geotextile may be held in place prior to subbase placement with pins,sand bags,or piles of fill or rock.On curves,the geotextile may be folded or cut to conform to the curve as illustrated in Figure 5-1.If site conditions require geotextile seaming,the geotextile shall be cut and seamed on the curve.The fold or overlap shall be in the direction of construction and shall be held in place as prescribed above.The geotextile shall not be dragged across the subgrade. Damaged geotextiles,as identified by the engineer,shall be repaired immediately.The damaged area plus an additional 3 ft.around the damaged area shall be cleared of all fill material.A geotextile patch extending 3 ft.beyond the perimeter of the damage shail be constructed as directed by the engineer.Sewing of a geotextile patch may be required over soft subgrades as directed by the engineer.Damaged geotextiles shall be repaired at no cost to the owner, Aggregate Placement:The aggregate base or subbase (aggregate)shall be placed by end dumping adjacent to the geotextile or over previously placed aggregate.End dumping or tail gate dumping of aggregate on the geotextile will not be permitted.The aggregate shall be spread from the backdumped pile using a bulldozer.A sufficient thickness of aggregate should be in place prior to dumping to minimize the potential of subgrade pumping and localized subgrade failure. The aggregate shall be placed on the geotextile in lifts not less than 6 in.thick.For lowvolumeroads,the minimum lift may be reduced to a 4 in.thickness at the discretion of the engineer.Traffic shall not be permitted directly on the geotextile.Sudden stops or turns by equipment operating on aggregate placed over the geotextile shall be avolded.A smooth drum roller shall be used to achieve specified aggregate density.Any ruts occurring during construction shall be filled with additional aggregate and compacted to the specified density.Vibratory compaction shall not be used on the initial lift over the geotextile, JUN.-02'99 (WED)15:51 POLAR SUPPLY CO.INC.TEL:907 562 7001 P.007 TABLE 5-1 PHYSICAL REQUIREMENTS"22 GEOTEXTILES IN SEPARATION APPLICATIONS Property Units Required Values Test Method Medium HighSurvivability'|Survivability' Tensile -- Strength Ibs 180 270 ASTM D 4632 Elongation %50 50 ASTM D 4632 Seam Strength Ibs 160 240 ASTM D 4632 Puncture Strength Ibs 70 100 ASTM D 4833 TrapezoidTear Ibs 70 100 ASTM D 4533 Strength Permittivity Vsec 02")02")ASTM D 4491 Apparent U.S.Opening Standard '6)'6)ASTM D 4751SizeSieve Steiine %70 70 ASTM D 4355 Notes: 1.Conformance of geotextiles to specification property requirements shall be determined according to ASTM D 4759,"Practice for Determining the Specification Conformance of Geosynthetics' 2.Contracting agency may require a letter from the manufacturer certifying thegeotextilesmeetspecificationrequirernents. 3.All numerical values,except those of elongation,represent minimum average roll values (i.e.,average test results from any sampled roll in a fot shall meet or exceed the minimum average roll values)in weaker principal direction.Values of elongation represent maximum average roll values.Lot sampled according to ASTM D 4354, "Practice for Sampling Geosynthetics for Testing” JUN.-02'99(WED)15:51 POLAR SUPPLY CO.INC.TEL:907 562 7001 P,008 METHOD OF MEASUREMENT Geotextile:The geotextile shall be measured by the number of square yards from the payment lines shown on the plans or from the payment lines established in writing by the engineer.This excludes seams and overlaps.Excavation,backfill,bedding,and cover material are separate pay items.
