Until the EHD notifies you that this site qualifies for <br /> site closure, sampling and monitoring the wells are still required. Please sample all monitoring wells for <br /> all current and previously suspended analytes during the fourth quarter 2011. The EHD will allow a two- <br /> month remedial shut down period to conduct a rebound test. Please reactivate the soil vapor extraction <br /> system after two months of shut-down and report the findings to the EHD. If you can support conclusions <br /> that no additional remedial efforts are needed, the EHD will continue with the NFAR process. <br /> In correspondence dated May 27, 2011, the EHD advised you that prior to a site being granted a no <br /> further action status, a soil vapor intrusion evaluation must be submitted to and approved by the EHD. A <br /> work plan to collect soil gas samples or submittal of a technical justification as to why no soil gas <br /> sampling is required is due at the EHD by November 18, 2011. If soil gas samples are to be collected, <br /> please follow San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) guidelines for <br /> Environmental Screening Levels (ESL) to determine if a potential vapor intrusion risk to the public is <br /> present from the residual contamination at the site. <br /> If you <br /> have any questions, please contact Michael infurna at (209)46�8--334554. <br /> Michael J.
