11i SIJ on the location of the utilities at the facility The boring and monitoring well installation and sampling will be performed as prescribed in the California Code of Regulations, Title 23, Chapter 16, Section 2649 3.1 Site Health and Safety PIan The site specific portion of E-Z Serve's Health and Safety Plan (HASP) is provided in Appendix A of this report The HASP was prepared in accordance with federal (29 CFR 19010 120) and state (8 CCR 5192) regulations for performing work at hazardous or potentially hazardous waste sites E-Z Serve's HASP (both the generic and site-specific portions) will be on-site during field operations All BRE personnel and subcontractors working on-site will be required to comply with all provisions of the HASP 3.2 Permits The proposed soil borings and monitoring well will be installed on the former E-Z Serve property, so off-site access agreements will not be required Prior to beginning work, BRE will obtain all necessary permits from San Joaquin County and the City of Manteca 3.3 Underground Utility Clearance Prior to beginning work, BRE will mark all proposed borings on the ground surface Underground Service Alert will be notified so that each utility company with underground services can mark their locations As a precautionary measure, each boring will be hand augured initially to a minimum depth of 5 feet 3.4 Soil Boring Installation Soil borings SB-1 through SB-8 will be installed using hydropunch technology The hydropunch is a direct push method for obtaining soil samples that generates no drill cuttings, thereby eliminating the disposal cost of derived waste Samples will be obtained from all borings at 5-foot intervals from ground surface to the water table and field screened with a PID Samples that register above 50 parts per million (ppm) using the (` PID will be submitted for laboratory analyses if no samples register greater'than 50 ppb,'[/ then the sampling interval with the highest PID reading will be submitted to the laboratory One sample will also be collected and analyzed from the capillary fringe in each boring The rationale for the proposed boring locations is as follows ` I I I • Soil borings SB-1, S13-2, and S13-3 will be installed adjacent to monitoring wells 1, 2, and 3, respectively Soil samples from these wells had the highest concentrations of petroleum hydrocarbons detected to date (Table 1) Since a risk assessment may be proposed' for this Site in a Corrective Action Plan , (depending upon the cost- effectiveness), additional samples will be necessary to, determine whether the I I I BRE-Fig "96-194/MY41-1 1 I
