Any comments from DTSC have been incorporated into this letter. <br /> Union Pacific Railroad (UPR) will be constructing a rail fabrication facility at the Port of Stockton in <br /> the spring of 2014. The proposed location of the facility and accompanying .railroad spurs will be <br /> located within several environmental sites at Port of Stockton which have (or had) impacts to <br /> groundwater from volatile organic compounds. These sites are identified as Sites 7, 8, IAS-10, <br /> IAS-11, IAS-13 and IAS-15. Twelve groundwater monitoring wells associated with these sites will <br /> need to be properly abandoned to make room for the UPR construction. In the Work Plan, ERS <br /> proposes to obtain well abandonment permits from San Joaquin County Environmental Health <br /> Department, and follow proper protocols as set forth in the permit. <br /> I concur with the Work Plan as proposed. Be advised that re-installation of some or all of the wells <br /> and/or piezometers will be required at a later date as deemed necessary by Central Valley Water <br /> Board and DTSC staff. In the Well Abandonment Report, please enclose a copy of the well <br /> abandonment permit. Please provide me and Mr. Salcedo with a one week notice prior to the start <br /> of field activities. <br /> If you have any questions, please contact me at (916) 464-4607 or kamaru@waterboards.ca.gov. <br /> KATHLEEN AMARU, P.G., C.E.G. <br /> Engineering Geologist <br /> cc-.
