6.4.4 DAILY COVER <br /> The top and inactive sides of the cells are covered with at least 6 inches of clean <br /> soil in a continuous operation as they are completed. The active, working face is <br /> covered with a minimum of 6 inches of daily cover. The daily cover is obtained <br /> from onsite stockpiles or excavations (see Base Grading Plan, Drawing 3), or <br /> recovered from on-site alternative daily cover operations (such as treated soil <br /> and low-contaminant-level,untrea il). The daily cover soil placement <br /> satisfies the regulatory cover requirements for the control of vectors;odor, fire, <br /> water infiltration and erosion, and for preventing unsightliness. The:operations <br /> manager is responsible soil,atthe. &Df <br /> each working day. <br /> 6.4.5 INTERMEDIATE COVER <br /> A minimum of 12 inches of intermediate cover obtained.from,.onsite excavations <br /> or stockpiles will be placed and vegetated on all landfill areas that will not be <br /> receiving additional wastes for at least 180 days:-The`thickness of the soil cover <br /> will be controlled by evenly spreading a volume of soil, corresponding to a 1- <br /> foot-thick layer, over a defined refuse fill area. A map depicting areas that have <br /> received intermediate cover will be maintained by the operations.mana,ger_..The <br /> intermediate cover soils are the same as the daily cover soils and meet the <br /> regulatory requirements for control of vectors, fire, odor, water infiltration, <br /> erosion, and the prevention of unsightliness. <br /> 6.4.6 ALTERNATIVE DAILY COVERS <br /> The Forward Landfill is permitted to reuse soils contaminated with petroleum <br /> hydrocarbons and synthetic fabrics as ADC, in addition to several other <br /> materials. Forward will continue to investigate other sources for daily cover <br /> materials, including those allowed in accordance with 27 CCR, Section 20690. <br /> As these types of ADC materials become available from the waste stream, <br /> Forward will inform the regulatory agencies of their desire to use these materials. <br /> Forward currently uses processed green waste as an ADC. When green waste is <br /> received at the site it is stockpiled for a period no longer that two weeks <br /> whereby a grinder is brought onsite and the material is processed and then <br /> placed as ADC. <br /> Forward Landfill JTD 6-7 <br /> L:\Allied\2000.193\Reports\fi naljtd:Sec-6.0:08/20/01 <br /> BRYAN A.STIRRAT 6 ASSOCIATES <br />
