Box 2009 <br /> Stockton. CA 95201 <br /> L1S IN R®A3� EI�7GH CAMP F1I�T.+ <" , MONITO NG RESULTS <br /> Attached are copies of the recent gas monitoring results tested by <br /> Twining Laboratories. <br /> The result indicates methane gas exceeding the lower explosive <br /> limits at soil gas probe #7 (8.550 at French Camp landfill and <br /> Soil gas probes #6 (9,10%) and. #11 (5 .054) at Austin Road landfill . <br /> None of the above soil gas probes are located at the property <br /> boundary. <br /> At French Camp landfill, Sail gas probe #1 and. #3 are the only <br /> probes not located in refuse. The remaining 5 probes are located in <br /> refuse due to the difficulty in installing the probes at the <br /> property boundary. <br /> Soul gait probeS #6 and #11 at Austin Road landfall also are not <br /> located at the - property boundaries. Soil probe #11 is set in <br /> refuse, and soil probe #6 is affected by the temporary <br /> disconnection of the extraction system installed by Pacific Energy. <br /> The City of Stockton feels that public health and safety is not <br /> endangered because of the following reasons e <br /> 1. The gas migration cannot~ occur due to the hydraulic barrier <br /> (Walker Slough and French Camp Slough) adjacent to Soil gas <br /> probe #7 at French Camp Landfill., and (Little John'e <br /> Creek) adjacent to Soil probe #6 at Austin Road landfill. <br /> 2. The property boundary is approximately 800° from Sail gas <br /> probe #11 at .Austin Road landfill and 1500° to' the <br /> southerly cyA fenced boundary. <br /> 3 . Both the Austin Road and French Camp landfill is gated and <br /> fenced for security purposes and the scale houses and all <br /> cargo boxes tested OAC LEL. <br />
