(39-AA-0001) <br /> Landfills, San Joaquin County; <br /> Demonstration Period November 1995 to August 1996 <br /> Final Evaluation <br /> This is the final report for French Camp Landfill (FCL) and <br /> Austin Rd. Landfill (ARL) Green Waste Alternative Daily Cover <br /> (GWADC) Project . Monitoring of this pilot project by <br /> Environmental Health Division (EHD) has been completed. EHD <br /> approves the use of GWADC for daily cover at ARL and French Camp <br /> Landfills during dry weather only. EHD has made the following <br /> evaluation. <br /> Green Waste (GW) Alternate Daily Cover (ADC) has proven to be an <br /> efficient cover for landfill wastes when spread correctly and <br /> when amounts of GWADC are available in sufficient quantities . <br /> During wet weather project monitoring there were problems with <br /> the operator not adequately covering wastes or not having enough <br /> green waste on site to use for cover. Uncovered or daylighting <br /> wastes and/or litter was observed by EHD at both landfills . <br /> Approved backup cover was not used at ARL. Soil was not moved to <br /> cover wastes and a Covertech tarp was used at ARL without EHD <br /> approval . <br /> In addition during wet weather other landfill operation and <br /> maintenance problems occurred and were not remedied in a timely <br /> fashion (ponding at FCL, leachate surfacing and runoff at ARL) . <br /> Communication problems between COS and their subcontractors was <br /> common and contributed to ongoing maintenance problems and <br /> difficulty following the GWADC plan. Later in the project <br /> monitoring period COS submitted addendum information to modify <br /> the original GWADC plan to remedy some of the problems . COS is <br /> currently working with their subcontractor in order to reduce <br /> litter in the GWADC. <br /> A Division of San Joaquin County Health Care Services <br />
