Port of Stockton - 3 - 27 May 2014 <br /> Rough and Ready Island <br /> Stockton, San Joaquin County <br /> notice. Data collected from the recent groundwater sampling conducted during monitoring <br /> well abandonment shall be utilized in the first semi-annual report. <br /> 3. Central Valley Water Board staff issued a letter to POS on 12 March 2014 that allowed the <br /> abandonment of twelve wells along the IAS-09/IAS-15 corridor. The purpose of the well <br /> abandonment was to facilitate construction of the UPRR line for POS. The Water Board's <br /> allowance to abandon these wells does not suggest or imply the value of the wells is <br /> diminished. It will be at the discretion of the Central Valley Water Board to have POS install <br /> additional replacement wells at a later date, if necessary. <br /> At this juncture, Central Valley Water Board staff sees no advantage to ERS producing a revised <br /> PEA for site IAS-09. The general comments provided in this letter shall serve for future reports <br /> generated by ERS regarding site IAS-09. <br /> By 15 July 2014: <br /> 1. Please provide a Work Plan to conduct additional site assessment at site IAS-09 (in its <br /> entirety). But, due to the urgent nature of conducting site assessment in the northern site <br /> area prior to UPRR construction (and the expansive size of IAS-09), Central Valley Water <br /> Board staff will concur with implementation of the Work Plan to be localized to the area <br /> between the northern boundary of the site and IAS-16 (the limits of the UPRR <br /> construction). <br /> 2. Please submit a proposal for semi-annual groundwater monitoring and reporting at site <br /> IAS-09. POS has not been conducting groundwater monitoring on a regular basis. To <br /> evaluate the need for additional site assessment and/or remedial action at site IAS-09, <br /> groundwater monitoring is necessary. POS has the option of providing this proposal on a <br /> voluntary basis, or if it is helpful, Central Valley Water Board staff can provide POS with a <br /> Monitoring and Reporting Program Order (MRP). <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: Mr. Jose Salcedo, DTSC <br /> Mr. John Yoajum, San Joaquin County Department of Environmental Health <br /> Mr. Mark O'Brian, ERS <br />
