water contamination and floating free product, a product skimming system was installed in these wells This system was installed and started removing free floating product on October 10, 1989 The system recovered approximately 40 gallons of floating product by October 28, 1989 reducing the free floating product found in the wells to a sheen. After receipt of the May 3 , 1989 letter from Mr. Wilbur H. Smith II, disapproving of Wickland' s plan to remediate ground water beneath the site, a slug test was performed on aech of the wells (MW1 MW10) , in conjunction with the scheduled quaterly ground water sampling on May 25, 1990 The slug tests were performed in lieu of conducting a pump test, out of concern that Lincoln Center did not want any ground water pumping to occur at the site This slug test data was incorporated into the draft Final Remedial Plan that was open for public comment until January 23, 1991 This plan (October-November-December, 1990 UPDATE STATUS REPORT, REPORT #4) also proposed vapor extraction and ground water pumping from MW1 and MW3 to mitigate the site. After the public review process, Mr. Wilbur H Smith II, was notified of our plans to construct a soil and ground water remediation system and requested his permission to trench across the parking lot behind the station to install a natural gas line to the treatment compound At this time the sewer discharge permit process was again started A phone conversation with Mr Larry Williams of the Sewer Treatment Plant on August 27, 1991 indicated that the City Sewer was no longer accepting any new permits for discharge of treated ground water to the city sewer system A meeting was arranged that day with Wickland and the City to discuss how we could obtain our delayed sewer discharge permit and a request for a Variance/Exemption was made . This request to discharge was denied, October 28 , 1991 . Discussions between the City Managers office and San Joaquin County Health were successful and Sewer discharge permits were again being accepted for treated ground water discharge to the sewer system We were finally able to obtain the sewer discharge permit on June 2, 1992 for 1, 200 gallon per day discharge . Mr Wilbur H Smith II in a letter dated July 22 , 1991, informed us that Lincoln Center was conducting an ongoing remedial investigation and requested information regarding the proposed remediation system and the system' s effectiveness in destroying PCE, TCE and cis-1, 2, DCE. At this time we requested information from Mr Wilbur H Smith II concerning the Lincoln Center investigation This information was not forthcoming. It was noted however, that the Lincoln Center PCE plume had not been fully defined and a concern existed that aggressive ground water pumping might pull their plume towards our site, after various phone conversations with San Joaquin County Health (Eleanor Ratliff and Diane Hinson) and Mr. Gerry Nakano of Kennedy/Jenks (consultants for Lincoln Center) Although we have been sending Mr Wilbur H Smith II our reports since his request, as of this writing (March 3 , 1994) we have not received any information 2
