(Raney) and has the following comments. <br /> In the Work Plan Raney proposes the remediation by excavation of residual petroleum <br /> hydrocarbon contamination in soil discovered at the former location of an underground storage tank <br /> (UST)on the above referenced property. The tank was used as part of a farming operation. Prior <br /> fieldwork has documented soil contamination vertically to less than 30 feet below surface grade <br /> (bsg) near the east end of the former UST, and less than 10 feet laterally. The proposed <br /> excavation dimensions are approximately 15 feet square by 25 feet deep; proposed confirmation <br /> sampling is one per sidewall and one from the bottom of the excavation. The construction <br /> contractor hired to perform the excavation will submit a site-specific health and safety plan. The <br /> excavation will be conducted using appropriate equipment and safety protocols dictated by the <br /> scope of work and the lithology. Benching and/or shoring may be required to reach the proposed <br /> total depth of the excavation. <br /> SJC/EHD approves the Work Plan with the following comments: <br /> 1. Petroleum hydrocarbon contamination was documented in boring B-3 at 25 feet bsg. The <br /> excavation contractor should be prepared to go below this depth if necessary to remove all <br /> detectable contamination. <br /> 2. Department of Toxics Substances Control (DTSC) has requested that two additional <br /> confirmation soil samples be collected from the bottom of the excavation to ensure removal <br /> of all contamination noted in boring B-2. <br /> If you have any questions please call Lori Duncan at (209)468-0337. <br /> Donna Heran, RENS, Director <br /> Environmental Health Department <br /> Lori Duncan, Senior REHS Margaret L g�"EHS`J <br /> Mitigation Unit IV Program Coordinator Unit IV <br /> cc: Maria Gillette, DTSC, 8800 Cal Center Drive, Sacramento, CA 95826 <br /> Pete Ruttan, Raney Geotechnical, 3140 Beacon Blvd, West Sacramento, CA 95691 <br /> Steve McAdams, 314 Tamarron Way, San Ramon, CA 94582 <br />
