Harding Way <br /> Stockton CA 95204 <br /> In correspondence dated February 17, 2004 you were notified by San Joaquin County <br /> Environmental Health Department (SJC/EHD)that "Revised Remedial Action Plan and <br /> Work Plan for Ozone Sparge Well Installation"dated February 9, 2004 submitted on your <br /> behalf by SECOR International Incorporated (SECOR) was approved. You were directed <br /> to proceed with submittal of a San Joaquin County well permit application, required <br /> $89.00 permit fee and copies of any necessary encroachment permits and/or access <br /> agreements from offsite property owners. <br /> It has been a year since this proposed remediation was approved. Interim remediation of <br /> the site continues by onsite dual phase extraction and offsite periodic batch groundwater <br /> extraction. However, the concentrations of MtBE in the monitoring and extraction wells <br /> located on the north side of Harding Way remain very high, and the plume appears to be <br /> moving further towards the northeast. In addition, concentrations of contaminants in wells <br /> MW-1, MW-3 and MW-5 are increasing. <br /> Please proceed with submittal of the requested documents, and with scheduling the <br /> approved work. The deadline for the installation of the ozone sparge points and system <br /> startup is April 29, 2005. <br /> If you have any questions please call Lori Duncan at (209) 468-0337. <br /> Donna Heran, REHS, Director <br /> Environmental Health Department D 1 <br /> Lori Duncan, Senior REHS Margaret La no, Supervising REHS <br /> LOP/Site Mitigation Unit IV LOP/Site Mitigation Unit IV <br /> cc: James Barton, CVRWOCB <br /> Clint Harms, SECOR <br />
