Site Code: 1090 640 N. EI Dorado Street Stockton, CA The San Joaquin County Environmental Health Department (EHD) has overseen the assessment and cleanup activities at the above subject site since May 1998. A 250 gallon underground storage tank (UST) for waste oil was removed from the site on March 26, 1997. There were high concentrations of total petroleum hydrocarbons as diesel and motor oil and low concentrations of Tetrachloroethene in the soil sample collected beneath the UST at the time of removal. In June 2001 free product motor oil was discovered in the monitoring well placed in the former UST location. Free product removal was discontinued in April 2006 since there were no longer observations of free product. The State Water Resouces Control Board Cleanup Fund was reimbursing the responsible party (RP) for corrective action costs initially but in May 2006 informed the RP that no additional costs would be reimbursed because the investigation was for solvents not petroleum. The attorney for the RP has appealed that decision but to date the decision has not been reversed. The EHD and Central Valley Regional Water Quality Control Board staff met with the RP's representatives, attorney and consultant on June 6, 2006 and March 20, 2008 to discuss the further investigation that was required. The last quarterly monitoring and sampling of the site monitoring wells was on June 20, 2006. Work plans that were submitted in February 2005 and March 2008 and were approved by the EHD have not been implemented. In a telephone conversation with the RP's consultant on May 12, 2008, the EHD was informed that there has been no instruction from the RP representatives to implement the current work plan or resume quarterly monitoring. Enclosed is a chronology showing the responsible party's history of recalcitrance in responding to regulatory directives and performing work at the site.
