Ranch Market 2 . 19 July 2011 23569 Santa Fe Rd., Riveak San Joaquin County Remediation Plan was approved by Staff. The SVE system began operation in September 2002, followed by a groundwater Ozone Sparge (injection) System startup in November 2002. In a SJCEHD letter dated 26 February 2004, after free product was discovered in monitoring well MW-3, SJCEHD notified you that they were now the lead agency for the USTs case, and required free product removal from MW-3. Ozone injection was stopped in December 2004, and dual phase extraction was tested and rejected as not effective by June 2006. SVE continued until 9 June 2008 with SJCEHD approval. A Multiple Interface Probe (MIP) groundwater investigation work plan was approved by SJCEHD on 4 September 2007, and the MIP work was completed in August 2008. As stated above, the MIP report has not been received. Ten groundwater monitoring wells (MW-1 through MW-9, and MW-5D) and three domestic wells (DW-1 R, DW-3, and DW-4) were monitored at the Site in September 2008, when maximum groundwater concentrations (MW-3) were TPHg, 86,000 micrograms per Liter (ug/L); benzene, 270 ug/L; toluene, 57 ug/L; ethylbenzene, 630 ug/L; xylenes, 6,300 ug/L; 1, 2-dichlorethane, 0.7 ug/L; tert butyl alcohol, 5.2 ug/L; and MTBE, 7.8 ug/L. When the domestic wells were last monitored in November 2008, all domestic well results were non-detect for petroleum hydrocarbons. You are currently out of compliance with regulatory directives, which may result in formal enforcement action pursuant to the California Water Code, which does include the imposition of civil administrative liabilities (fines) of up to $1,000.00 per day per violation. However, Regional Water Board staff would prefer the opportunity to work with you, to move this USTs case into compliance with future directives and eventually towards closure. As such, we request that you meet with us on one of the following dates: Monday, 15 August 2011 or Tuesday, 16 August 2011. In order to schedule the meeting, please contact Jim Munch by 4 August 2011, either by phone at (916) 464-4618 or he can be reached by e-mail at jmunch(c)-waterboards.ca.00v. ,l - James L.L.
