II. Project Description <br /> ensure that adequate compaction would be achieved,the q <br /> compaction equipment would traverse <br /> P <br /> the entire length of the working face and make a minimum of four passes over each two-foot <br /> thick layer of refuse. <br /> The completeness of compaction would be judged in the field by noting when the"spring-back" <br /> of the refuse has been reduced to a minimum,or when compactor cleats do not sink into the <br /> refuse,but instead are visible"walking" on the surface. <br /> As required by State regulations,cover soil would be spread and compacted at a minimum <br /> compacted thickness of six inches over all solid waste at the end of each working day. Cover <br /> depth would exceed six inches if necessary to completely cover the waste material. The daily <br /> cover would: <br /> • prevent vectors from feeding and breeding in and around the refuse disposal area; <br /> • minimize the potential for fires in the refuse; <br /> • control blowing litter from the working face; <br /> • control odors from the working face; and <br /> • complement the stormwater separation and diversion system. <br /> The daily cover soil would be placed by scrapers and/or bulldozers to an uncompacted thickness <br /> of about 12 inches. Compaction of the cover would be achieved by the weight of the scrapers <br /> and bulldozers passing over it. Following initial compaction of the soil cover and some <br /> infiltration of soil into the underlying waste,the compacted depth of the soil would be <br /> approximately seven to eight inches on average,which exceeds the six inch minimum <br /> requirement. <br /> In general,on-site material from cell excavation and borrow pit areas would be used for daily <br /> cover. During any new excavation, soils suitable for use as liner or final cover materials would <br /> be collected and stockpiled in an area designated by the landfill operator. During construction of <br /> new cells, materials excavated from the future cells, not suitable for liner or final cover,would be <br /> excavated and placed as cover without intermediate stockpiling,whenever possible. <br /> Actual usage of daily cover soils would be monitored on a regular basis. Records of cover soil <br /> monitoring would be keptin the landfill administrative office. The monitoring would consist of- <br /> H.26 <br />
