These two technical documents were submitted in response to Regional Water Quality <br /> Control Board Staff's (Staff) comments concerning the Final Closure Plan, French Camp Landfill. <br /> Staff has the following comments concerning these technical documents: <br /> 1. The French Camp Landfill Sediment Sampling Results reports the results of a sediment <br /> investigation in French Camp and Walker Sloughs. The investigation was undertaken to <br /> determine the extent and impacts of waste discharged outside the landfill footprint. The <br /> investigation was premised on the belief that complete removal of all waste in the sloughs would <br /> require significant disturbance of existing wetlands. If extensive contamination is found then <br /> removal and remediation of the outlying waste with subsequent disturbance of wetlands would be <br /> justified. Alternatively, if extensive contamination is not found then selective removal of waste <br /> would be undertaken with subsequent'less damage to the wetland environment. <br /> 2. The Sediments Investigation consists of sixteen sediment samples collected in French Camp and <br /> Walker Sloughs on the north, west and south perimeter of the landfill. Two of the samples (3 <br /> and 9) detected metal concentrations elevated above local background concentrations, none of <br /> the samples found detectable levels of organic constituents. The document recommends a <br /> limited follow-up of the vicinity of samples 3 and 9. The follow-up investigation to consists of <br /> total and WET analysis of sediments and tissue analysis of benthic organisms for selected metals. <br /> Staff concurs with this recommendation. <br /> 3. Concurrently with the follow-up, the Forward Inc. should devise a detailed plan for Staff review <br /> justifying the extent and method of selective waste removal from the sloughs. This plan should <br /> be submitted to the Department of Fish and Game (and other agencies?) for their review. <br /> California Environmental Protection Agency <br /> Recycled Paper <br /> The energy challenge facing California is real.
