OHM RemediationServices Corp. WORK PLANstockpiles will be composed of approximately 200 cubic yards of soil and will be physicallyseparated by plastic sheeting or an open area from the adjacent stockpile. Separate areas forcontaminated and uncontaminated soil will be demarcated at extreme ends of the stockpile areato prevent any mixing of soil. All stockpiles will be covered with polyethylene sheeting toprevent excessive precipitation from saturating the soil, reduce potential odors from thestockpile area, and prevent unauthorized personnel access to contaminated soil stockpiles.To verify the disposition of the soil stockpiles, waste characterization samples will be collectedfor laboratory analysis. Both contaminated and uncontaminated soil stockpiles will besampled. The specific methods, frequencies, documentation, and tests are described in theSAP. If the results of the tests show TPH above the criteria, then the stockpile should bescheduled for shipment to a disposal/treatment facility. If the results show TPH levels belowthe threshold, then the stockpile should be considered a candidate for use as backfill.Geotechnical data should be acquired for the soil and all laboratory analysis should beassembled for submittal to the NTR as discussed in Section 7.0.6.3 LOAD-OUT AND TRANSPORTOnce laboratory chemical analyses indicate which soil stockpiles are contaminated, thecontaminated soil stockpiles will be scheduled for removal from the site. Trucks will bemobilized to the site where they will be loaded with contaminated soil for transport to atreatment disposal facility. All waste destined for off-site disposal/treatment will betransported by a licensed hauler in accordance with North Carolina regulations.Temporary loading areas will be demarcated using flagging and will be near the contaminatedsoil stockpiles. During loading, a technician will be on hand to aid loading, verify properprocedures are followed, inspect the vehicles for adherence to regulations such as tarping,tailgate seals, stop lights, etc. Additionally, the technician will brush soil from the outside oftrucks and monitor loading to minimize spillage. If necessary, a pressure washer can be usedto remove contamination. All water from decontamination operations will be collected forappropriate disposal. Finally, prior to the truck leaving the site, the technician will verify thatthe driver is in possession of all proper documentation. These activities will be recorded on ashipping log detailing information such as truck number, bill of lading number, tarping,cleanliness of vehicle, estimated or actual tonnage shipped, time of entry to area, time of exitfrom site, etc. Transport vehicles will be given directions and instructed to proceed directly tothe treatment/disposal facility and dispose of the contaminated soil. Once at thetreatment/disposal facility the drivers will submit all necessary documentation for disposal oftheir load.OHM Project 1448lWP work Plan May 1995Iafomutioa herein is pmprieury and confidential and to be used or released to others only with explicit written permission of OHM Remcdiation ServicesCOrp.6-3
