1 , s <br /> Mr. Jay Jahangire • -2 - • 5 July 2001 <br /> 4. The Port requested that future monitoring wells be constructed with 12-inch traffic-rated covers <br /> with a two-foot concrete pad to help prevent damage from vehicular traffic. In addition, Port <br /> staff recommends using schedule 80 PVC for the construction of the wells to prevent casing <br /> failure caused by heavy equipment. <br /> 5. Twelve monitoring wells are proposed along roads not currently intended for development. <br /> These wells will further delineate the lateral and vertical extent of groundwater contamination in <br /> the four identified water-bearing zones. <br /> 6. There are four monitoring wells proposed within the undeveloped 23-acre parcel east of the <br /> POSDEF co-generation plant. The Port is currently negotiating with potential tenants to <br /> construct an energy production plant on the undeveloped parcel. Based on the Port's tentative <br /> schedule, these monitoring wells are not feasible in the proposed locations. After STTC installs <br /> and samples the other 12 proposed monitoring wells and the Port receives plans for the energy <br /> production plant, we can evaluate options for installing the additional monitoring wells. <br /> 7. There is currently no active groundwater remediation implemented at the STTC facilities. <br /> Stephen Lofholm noted that he submitted a feasibility study with a proposed remedial action to <br /> his clients for review and upon STTC approval will be submitted to Board staff. <br /> If you have any questions, you may contact me at(916) 255-3119 or lewisd n)rb5s.swrcb.ca.gov. <br /> DEVRA LEWIS <br /> Environmental Specialist II <br /> cc: Ms. Margaret Lagorio, San Joaquin County Public Health Services, Stockton <br /> Mr. Michael Luksic, Port of Stockton, Stockton <br /> Mr. LeRoy Hieber, Port of Stockton, Stockton <br /> Mr. Gary Gentry, Port of Stockton, Stockton <br /> Mr. Robert Donovan, Tesoro Petroleum Companies, Auburn, WA <br /> Mr. Ralph Moran, Arco Products Company, La Palma <br /> Ms. Ann Duarte-Wilkinson, Time Oil Company, WA <br /> Mr. Kyle Mullins, ST Services, TX <br /> Ms. Jill Jefferson, Kinder Morgan Energy Partners, L.P., Orange <br /> Mr. Steve McDonald, Luce, Forward, Hamilton, and Scripps, San Diego <br /> Mr. Stephen Lofholm, IT Group, Sacramento <br />
