Mr. Ray Baglietto and Mr. Frank Razui - 2 - 5 November 2003 PROJECT DESCRIPTION The Speedy Foods`site is currently a convenience food shop and no longer dispenses vehicle fuel. In January 1998 three underground storage tanks (USTs) were removed. Soil samples from beneath the removed LTSTs were collected and analyzed. Elevated concentrations of petroleum hydrocarbon contamination were found. From March 1998 to the present numerous soil borings and 14 groundwater monitoring wells have been installed and sampled. As a result of the investigative activities, San Joaquin County Environmental Health Department (SJCEHD) staff determined that remedial measures were required to clean up the identified contaminant plume. In a meeting with you on 22 July 2003, SJCEHD requested that you conduct interim groundwater remediation, utilizing pump and treat technology, which requires a permit from the Regional Board to discharge treated groundwater to Iand. Speedy Foods will pump contaminated groundwater from MW-1 and pass the groundwater through two 2,000-1b in-line activated carbon canisters for hydrocarbon stripping prior to being reapplied by a sprinkler system onto an open field on the property downgradient of the existing contaminant plume. The remedial process will remove the petroleum hydrocarbons. Analytical testing will be performed on the untreated influent and the treated effluent before it is discharged to the distribution discharge system. There are no surface waters associated with this project. ADDITIONAL REQUIREMENTS 1. For this project, Speedy Foods is to analyze for total petroleum hydrocarbons, TPH, as gasoline (TPHg); benzene; toluene; ethylbenzene; total xylenes; fuel oxygenates including MTBE; lead scavengers; volatile organic compounds including ethanol, methanol, and trimethylbenzenes; polynuclear aromatic hydrocarbons, and general minerals only. Samples are to be collected and ana,yzed in accordance with locations and frequencies directed in the General Order and associated MRP. Pesticides are waived from the sampling and reporting requirements because thev were not detected in previous sampling of the groundwater. 2. The required annual fee (as specified in the annual billing invoice to be issued by the State Water Resources Control Board) shall be submitted until this NOA is officially withdrawn. If you have any questions regarding this NOA, please telephone James Barton at (916) 255-3115. K, L1 ,,q) P", THOMAS R.
