6.4.7 SPECIAL HANDLING PROCEDURES <br /> The following sections describe special handling procedures for land <br /> treatment units, sludge treatment and disposal and disposal methods for <br /> asbestos, ash and treated wood waste. <br /> 6.4.7.1 LAND TREATMENT UNITS <br /> Although most contaminated soils accepted at the existing Forward Landfill are <br /> disposed directly into Class II WMUs or are used as daily cover, Forward may <br /> occasionally choose to temporarily stockpile or treat certain contaminated soils. <br /> Soils that are temporarily stockpiled are typically those that have been received <br /> at the site without the required analytical testing documentation. The soils are. <br /> stockpiled until the generator provides the necessary documentation. Once the <br /> documentation is received and depending on the test results, the soils are <br /> either disposed in an appropriate WMU or removed from the site by the <br /> generator. <br /> In order for Forward to process a request for treatment or disposal of <br /> contaminated soil, the potential disposer/generator must complete a waste <br /> characterization form and a contaminated soil description form (signed by a <br /> California Registered Geologist or California Professional Engineer),-and submit <br /> copies of all state-certified laboratory results for the contaminated soils. <br /> In the past, Forward has implemented programs for treating both gasoline and <br /> nonvolatile petroleum hydrocarbon contaminated soil. A brief operations <br /> summary for treatment of both of these contaminated soil types follows. <br /> Treatment of Nonvolatile Petroleum Hydrocarbon Contaminated Soil <br /> The "Operation and Maintenance Manual, Soil Treatment System, Forward, <br /> Inc., Landfill Unit WMU G, Stockton, California" (Harding Lawson Associates, <br /> April 1991) describes the treatment system for nonvolatile petroleum <br /> hydrocarbon contaminated soils. The specifications and reporting requirements <br /> of the treatment system are specified in the WDRs, Order No. 97-141 and in <br /> Forward Landfill JTD 6-12 <br /> L:\Allied\2000.193\Reports\finaljtd:Sec-6.0 6-9-03:5/22/02 <br /> Rev. 1: 7/2002: Rev. 2: 4/2003; Rev 3: 6/2003 <br />
