Ms. Vera Fischer, P.G., RWQCB <br /> February 28, 2018 <br />Work Plan for Additional Site Assessment Project No. 2154-1817-01 <br />1817 South Fresno Avenue, Stockton, CA <br />Page 6 <br />Task 3: Laboratory Analysis <br />Groundwater samples will be forwarded to a state-certified laboratory for chemical <br />analysis. The samples will be analyzed for GRO using USEPA Method 8015, and for <br />benzene, toluene, ethylbenzene, and total xylenes (BTEX compounds), and MTBE using <br />USEPA Method 8260. Groundwater and soil gas analytical data will also be uploaded to <br />the State of California's GeoTracker database. <br />Task 4: Site Assessment Report Preparation <br />Following completion of the subsurface investigation activities, a report will be submitted <br />to document the work activities performed and to present the findings associated with this <br />work. The report will include, but not be limited to, a scaled site plan, CPT results, an <br />updated geologic cross section, tabulated analytical data, and certified analytical results. <br />The report will also document deviations from this Work Plan, if any. <br />SCHEDULE <br />Following approval of this Work Plan, an encroachment permit and revocable permit <br />application will be prepared and submitted to the City of Stockton. Once a revocable <br />permit and encroachment permit have been obtained, Stratus will apply to the SJCEHD <br />for a drilling permit and the work will be scheduled. Stratus anticipates that <br />approximately 3 to 4 months will be necessary to obtain all of the necessary permits to <br />implement the investigation once this Work Plan is approved by the RWQCB. <br />LIMITATIONS <br />This document was prepared in general accordance with accepted standards of care that <br />existed at the time this work was performed. No other warranty, expressed or implied, is <br />made. Conclusions and recommendations are based on field observations and data <br />obtained from this work and previous investigations. It should be recognized that <br />definition and evaluation of geologic conditions is a difficult and somewhat inexact <br />science. Judgments leading to conclusions and recommendations are generally made <br />with an incomplete knowledge of the subsurface conditions present. More extensive <br />studies may be performed to reduce uncertainties.
