The line was directionally drilled through the top of the tank that was <br /> subsequently exposed in an exploratory excavation. No evidence of USTs or associated contaminated <br /> soil was encountered in the utility directional drilling pit. <br /> The San Joaquin County Environmental Health Department (SJCEHD) was notified and performed a <br /> site inspection. According to the Notice to Abate dated October 24, 2012,the SJCEHD inspector noted <br /> that the top of the tank was sheared off and the UST contained fluid but did not note any odor. <br /> Comcast's Contractor confirmed that the fluid was generated during the directional drilling operations. <br /> The Notice to Abate requires permitted removal or proper in-place abandonment of the tank. <br /> We completed a geophysical survey and performed two soil borings (131 and B2) adjacent to the UST <br /> in November 2013 as reported in our December 11,2013, UST Site Investigation Report.No evidence <br /> of UST-related petroleum hydrocarbon impacts was identified. <br /> PURPOSE AND PROJECT SCOPE <br /> The purpose of the scope of services outlined in TO No. 34 is to remove the UST in accordance with <br /> SJCE14D permit requirements. <br /> Outlined below is a summary of the completed scope of services: <br /> 3160 Gold Valley Drive,Suite 800 0 Rancho Cordova,CA 95742-7515 0 Telephone 916.852.9118 0 Fox 916.852.9132 <br />
