Box 1210 <br /> Lodi, CA 95241 <br /> STATUS OF CLEANUP AND ABATEMENT ORDER 93-701 (C&A), 16 SOV771 CAEROREE LANE, LODI, <br /> SAN JOAQUIN COUNTY <br /> I reviewed your file tO determine the status of the investigation and cleanup to date and your <br /> compliance with the C&A issued 15 March 1993. Following is a summary: <br /> - The site investigation was completed by the dates specified. <br /> - For the most part, quarterly reports contain"the required information and have been submitted <br /> on time. <br /> The Final Remediation Plan (FRP) was submitted on time, but was incomplete. Additional <br /> information was requested and after submittal, a Bioremediation Pilot Study was performed <br /> several months after the C&A required that remediation begin. <br /> - After completion of the Pilot Study, Board staff had reservations about the efficacy of the in- <br /> situ bioremediation, however, we agreed to the implementation of a full scale project at the <br /> site. <br /> The bioremediation program began in August 1994, almost a year after the date required in the <br /> C&A. <br /> After one full year of bioremediation, evidence of contaminant reduction is limited. <br /> We met with you and your consultant in October 1995 to discuss the progress of remediation at your <br /> site. Your consultant proposed to modify the bioremediation program. A work plan containing the <br /> proposed bioremediation modifications was also to include a plan for a down-gradient well, additional <br /> assessment of existing site information, and a time schedule. The work plan was submitted <br /> 15 December 1995 as we agreed. <br /> We will continue working closely with you to complete remediation of your site to allow eventual <br /> closure. If you have any questions, call me at (916) 255-3133. <br /> ELI ETH A.
