G Y <br /> Michael Hanford <br /> Page 2 <br /> Please be informed that all tank violations must be corrected by May 10, 1995. If you have any <br /> questions regarding the operation of tanks, please contact Letitia Briggs at (209) 468-3468. <br /> County Administer's Office, Capital Improvement Projects <br /> 145 South Sutter. Stockton <br /> Dick Callistro indicated that he received a draft work plan which he would review and finalized to be <br /> forwarded to PHS/EHD within 4 weeks (April 7, 1995). He indicated that the work plan proposed to <br /> install two replacement wells for MW2 and MW3 and destroy well MW2 and MW3. PHS/EHD staff, <br /> Mary Meays, indicated that additional soil investigation would be required to determine the extent of <br /> the residual soil contamination and hence whether or not additional remediation would be required. <br /> Government Buildings Sites <br /> 130 North Hunter St., Stockton- Steve Sasson <br /> Craig Ogata indicated that the tanks will be removed prior to further investigation. The removal is in <br /> the procurement phase and will be out to bid. <br /> 222 East Weber Ave.. Stockton- Steve Sasson <br /> Although detection limits at the time of the removal were higher than current recommended detection <br /> limits, PHS-EHD will provide a clean tank closure status to this UST, based upon ND at 0.025 ppm <br /> and the inspector's observations. A clean closure letter will be issued by PHS-EHD. <br /> 24 South Hunter St. Stockton- Michael Infuma <br /> The petroleum underground storage tank (UST) is improperly abandoned in place in the sidewalk area <br /> west of this county building. In an attempt to satisfactorily determine if a serious problem exists in the <br /> subsurface area around the UST, PHS-EHD recommends that a confirming soil sampling event in the <br /> area of the previous boring (13-5) be conducted. Soil samples and a groundwater grab sample should <br /> be collected and analyzed for the same constituents that were detected in the previous investigation. <br /> The results obtained during this investigation will help determine if the site may be certified for closure <br /> or require further investigation and/or remediation. In addition to the recommended sample collection <br /> event, a UST Closure Plan shall be submitted to Letitia Briggs at PHS-EHD as soon as the <br /> determination has been made regarding the status of the soil and groundwater beneath the UST. <br /> Please direct your work plan submittal and any questions you may have to Michael Infuma at (209) <br /> 468-3454. <br />
