Recommended Conditions of Approval February 20, 2014 <br />PLN2013-00045; 1333 Martinez Street Page 8 of 20 <br />analyses may be required, based on the intended disposal or re-use of the <br />water. <br /> <br /> Additional Soil Management Protocols During Construction Activities: Soil <br />with residual COPCs may be present on-site. Subsurface investigations <br />planned for the Sites will determine the presence or absence of COPCs in <br />soils. Once soils are tested, a Site specific soil management plan (SMP) will <br />be prepared. At the present time, there are no known chemical source areas or <br />areas of soil contamination on either Site. The protocols to be followed in the <br />event that unknown areas of contamination are identified during development <br />are described in this section. <br /> <br /> Procedures for Discovery of Unknown Areas of Contamination: Site <br />development activities may result in the identification of previously unknown <br />areas or types of contamination. Unknown conditions which may trigger <br />contingency monitoring procedures during site development include, but are <br />not limited to, the following: <br /> <br /> Oily, shiny, or chemical saturated soils; <br /> Soil with a significant chemical or hydrocarbon-like odor; or <br /> Significantly discolored soils. <br /> <br />Upon the discovery of one of the conditions identified above, the contractor will <br />conduct the contingency monitoring. Contingency monitoring, if conducted, will <br />consist of the following steps: If unknown areas of potential discolored soils are <br />encountered, additional analyses should be conducted for the suspected <br />constituents to assess the actual composition of the suspected contamination. A <br />State environmental regulatory agency should be contacted for assistance in <br />determining if additional sampling and potential mitigation is necessary. If the <br />encountered materials are suspected to contain volatile organic chemicals, the <br />following contingency monitoring procedures may be followed: <br /> <br />Conduct contingency monitoring by taking organic vapor readings using an <br />organic vapor meter (OVM) or an organic vapor analyzer (OVA) to screen for the <br />presence of fuel, oil, or solvents. If the OVM/OVA indicates that an unknown <br />area of fuel, oil, or solvents has been detected, then a State environmental <br />regulatory agency should be notified to determine if additional sampling is <br />appropriate prior to continuing construction in that area. OVM or equivalent <br />screening methods will be conducted by experienced personnel only. <br /> <br /> If an unknown area of soil contamination has been identified, and the State <br />environmental regulatory agency requests additional characterization, the <br />following steps will be taken: <br /> <br />o Soil samples will be collected from the identified area and analyzed for the <br />likely COPC, depending on the suspected type of contamination. The <br />sampling strategy will be discussed with a State environmental regulatory <br />agency prior to the initiation of the sampling activities. Analytical results <br />collected from the suspected source will be compared to the health-based
