CSK Auto#4025 GeoTek Project No.:BC 122-4025 <br /> Tracy,California 95376 Page 2 of 20 <br /> March 2,2000 <br /> maintenance is not conducted on the separator. GeoTek did not observe obvious <br /> indications of chemical staining in the vicinity of the floor drains. <br /> 1.3 ENVIRONMENTAL REGULATORY RECORDS <br /> No recognized environmental conditions were identified for the environmental regulatory <br /> records searched. <br /> 1.4 PREVIOUS REPORTS PROVIDED BY THE CLIENT <br /> CSK Auto did not provide previous reports for the subject property. <br /> 1.5 CONCLUSIONS AND RECOMMENDATIONS <br /> This Phase I Environmental Site Assessment has revealed evidence of recognized <br /> environmental conditions in connection with the subject site. <br /> • The facility currently utilizes a three-stage oil/water separator to intercept rinse water <br /> from the service area. Since routine maintenance and integrity of the interceptor are <br /> not known, GeoTek recommends sampling subsurface soils adjacent to the separator <br /> inlet and outlet connections to determine if the subject site soils have been impacted <br /> by chemicals utilized at the subject site. <br /> • Based on our site reconnaissance and interviews, GeoTek recommends subsurface soil <br /> sampling of the second hydraulic lift from the west. <br /> This executive summary does not contain all the information that is found in the full <br /> report. The report should be read in its entirety to obtain a more complete understanding <br /> of the information provided, and to aid in any decisions made or actions taken based on <br /> this information. <br />
