Manthey Road <br /> French Camp, CA <br /> San Joaquin County Environmental Health Department (EHD) has reviewed the <br /> "Limited Soil Assessment Silva Trucking Yard" report dated March 8, 2005, <br /> prepared by Kleinfelder, for the above referenced site. The report documents the <br /> results of a Phase II Environmental Study. A Site Approval application had been <br /> made to the San Joaquin County Community Development Department for truck <br /> parking on the site. EHD requested a Phase II Study on the tile road base, that <br /> had been placed on the site, for long term effects of the tile on soil and <br /> groundwater. Monier Lifetile and other sites in the county where spent tile has <br /> been taken have been found to have diesel range hydrocarbons, total chromium <br /> and chromium VI leach into the soil and groundwater from the tile. <br /> The lead regulatory agency for the investigations and cleanup at the Monier <br /> Lifetile and other spent tile sites is the California Regional Water Quality Control <br /> Board, Central Valley Region (CVRWQCB). The spent tile is a designated <br /> waste. The waste and any resulting contamination from it has to be investigated <br /> and cleaned up pursuant to the CVRWQCB requirements. <br /> Kleinfelder contacted EHD Unit IV regarding permit requirements for the <br /> investigation and were informed that a permit was not required if the soil samples <br /> were collected by digging with a shovel or by excavating. Kleinfelder was <br /> advised to work with EHD Unit II since it was their request to have the Phase II <br /> Study performed. EHD was not advised of or present during the soil sample <br /> collection. <br /> The analytical results of the soil samples collected were non detect for Chromium <br /> VI at a reporting limit of .05 mg/I but the sample dilution was from 10 to 100. <br /> Analysis for Total Chromium was not performed. One of the samples collected <br /> from beneath the tile road base area had .36 mg/I of diesel range hydrocarbons. <br />
