in the disturbance and redistribution of potential agricultural contaminants in the soil may require <br /> biased, discrete sampling. <br /> The DTSC's August 7, 2008 guidance states that "Based on data from former agricultural <br /> properties over the past seven years, the only pesticide class requiring analyses at agricultural <br /> properties are OCPs, such as DDT, toxaphene, dieldrin, etc. OCPs are biopersistent and <br /> bioaccumulate in the environment. Most other classes of pesticides have relatively short half-lives <br /> and have not been found in the agricultural fields. While paraquat does have a longer half-life in <br /> soil, it has either not been detected or detected rarely at trace levels at sites which DTSC has had <br /> oversight, therefore routine analyses for paraquat is not required for field areas." <br /> In consideration of the foregoing,Partner proposes to analyze ten soil samples from approximately <br /> two feet bgs (or from within native soil beneath recognized imported fill encountered at each <br /> sample location) at the historical locations of barns, sheds, outbuildings and portable agricultural <br /> equipment. <br /> 6.0 PROPOSED SCOPE OF WORK <br /> The proposed scope of work for the sampling of indoor air, sub-slab soil gas, soil gas, soil, and <br /> groundwater is outlined below. The methodologies and technical components of the scope of work <br /> are included in the SAP within Appendix B. Field work will be conducted as outlined in the HASP <br /> presented in Appendix C. <br /> 6.1 Pre-Field Activities <br /> Partner will delineate the work areas with white spray paint and notify Underground Services Alert <br /> North to clear public utility lines as required by law at least 48 hours prior to drilling activities. <br /> Partner will retain a private utility locator for the purpose of clearing specific boring locations <br /> using magnetometers and ground penetrating radar to identify, but not be limited to, electrical <br /> lines, sewer laterals, and storm water conduits. <br /> 6.2 Drilling Permits <br /> Partner will obtain the required drilling permits from the SJCEHD after the DTSC has approved <br /> of the Workplan. <br /> Sampling and Analysis Workplan <br /> Tracy Corners Shopping Center <br /> 3225 North Tracy Boulevard <br /> Tracy,California 95376 <br /> Partner Project Number SM14-129814 <br /> Docket Number HAS-VCA 14/15-108 <br /> August 15,2016 <br /> Page 21 <br />
