• To date USTF has reimbursed a total of $700,000. USTF currently owes Chapin Bros Inc $1,400.00 (Not billed) Chapin Bros Inc. owes the City of Stockton $22,000.00 for a sewer connection fee. January 22, 2009. Advanced Geological Engineering Summary of Site Remediation That remediation at the site has reduced hydrocarbon mass by approximately 95%. The overall technological difficulty of additional mass removal (the remaining 5%) is unlikely to make continued remediation cost-effective. Advanced Geological Engineering supports site closure for the facility based upon general site conditions, including; 1. The age of petroleum release with degradation of gasoline components (benzene) and a generally limited migration of benzene. 2) A well-defined dissolved hydrocarbon plume. 3) The lack of sensitive receptors; and 4) The low potential for beneficial use of the drinking water in the area of the site. Existing status State Water Resource Control Board position: Mr. Kirk Larson of the SWRCB stated with the current analytical data showing Benzene remaining the site could not be closed. He recommended additional effort using the Ozone method for the site. A preliminary draft work plan providing time and cost for the purpose effort was estimated at $221,901.with a time frame from February 1, 2009 to February 30, 2011. The San Joaquin County Environmental Health (SJCEHD) POSITION has denied our request for closure stating no technical basis has been established by which the Environmental Health Dept. can approve this action And the unauthorized release of fuel hydrocarbons and additives from former underground storage tanks (UST) system continues to be pose a threat to the groundwater and human health. That we have not demonstrated the plume will remain stable after cessation of active remediation by groundwater pump and treatment. When nor properly projected when water quality objectives will be met. That a significant mass and concentrated remain at the site. That the contaminated site is not well understood and that the site hydrology and geology was not thoroughly understood, characterized, and properly managed.
