t � 1 t. .e Privileged Attorney Work Product • KEEZEIIES • Marked the boring locations with white paint and contacted Underground Service Alert at least 48 hours prior to ground disturbance. In addition,the boring locations were cleared by a private utility locator service. • Contracted with a licensed (C-57) drilling company to complete the LSI using truck-mounted direct-push (Geoprobe) equipment. • Advanced three soil borings to five feet below ground surface (bgs) and collected discrete soil samples from the soil borings. • Submitted soil samples from each boring to a state-certified laboratory for chemical analysis. • Prepared this report summarizing the field activities and the laboratory analytical results. . A... E 3.0 PRE-FIELD ACTIVITIES Site access agreements were secured with the property owners prior to commencement of the fieldwork. Field activities were coordinated with the property owners in accordance with access requirements. Bureau Veritas obtained the appropriate drilling permit from the San Joaquin County Environmental Health Department(SJEHD). The SJEHD required a permit fee and on site grout inspector to be present during abandonment activities of the soil borings. Per the SJEHD permit requirements, a copy of the final LSI report is required to be provided to the SJEHD. The boring permit application and associated documents are appended. Bureau Veritas developed a SHSP for the work proposed in accordance with the requirements of the State of California General Industry Safety Order (GISO) 5192 and Title 29 of the Code of Federal Regulations, Section 1910.120_(29 CFR 1910.120). A copy of the SHSP was kept onsite during field activities. The SHSP detailed the work to be performed, safety precautions, emergency response procedures, nearest hospital information, and onsite personnel responsible for managing emergency situations. Prior to starting work, a "tailgate" safety meeting including discussion of the safety hazards and precautions relevant to the particular job was held with all personnel working on the job. Signatures of each person that attended the tailgate safety meeting were obtained and documented in the SHSP. 4.0 , FIELD ACTIVII TIES The following is a summary of the field activities that were completed during this investigation. 4.1 GEOPHYSICAL SURVEY AND UTILITY CLEARANCE On November 6, 2012, Bureau Veritas contracted with NORCAL Geophysical Consultants, Inc., located in Cotati, California, to complete a geophysical survey using ground penetrating radar(GPR) of an approximately 480 square-foot area of the subject property and to clear the three proposed boring locations. The geophysical survey did not identify anomalies of significance and/or indicative of large subsurface features such as USTs.The geophysical survey documentation is included in Appendix A. In addition, the three boring locations located within the 480 square-foot geophysical survey area were cleared of potential underground utilities. 2
