The specific scope of work is <br /> described below. <br /> SITE SPECIFIC HEALTH AND SAFETY PLAN <br /> As required by the Occupational Health and Safety Administration (OSHA) Standard <br /> "Hazardous Waste Operations and Emergency Response" guidelines (29 Code of Federal <br /> Regulations Section 1910.120), and by California Occupational Health and Safety <br /> Administration (Cal-OSHA) "Hazardous Waste Operations and Emergency Response" <br /> guidelines (California Code of Regulations Title 8, Section 5192), SECOR will prepare, or <br /> modify the existing, site-specific health and safety plan (SHSP) prior to the commencement <br /> of fieldwork. Field staff and contractors will review the SHSP before beginning field <br /> operations at the site. <br /> PIPELINE LOCATION VERIFCATION <br /> SECOR will verify the location of the Pipeline based on Chevron Pipeline as-builts. In <br /> addition to reviewing the as-builts, SECOR will meet with Chevron Pipeline personnel to <br /> validate the as-builts of the Pipeline. <br /> GROUNDWATER FLOW ROSE DIAGRAM PREPARATION <br /> The historical groundwater data from Chevron Service Station 9-8632 will be used to <br /> prepare a groundwater flow rose diagram. <br /> PIPELINE THROUGHPUT AND TESTING RECORDS REVIEW <br /> SECOR will obtain Pipeline product throughput and testing records, if available, from <br /> Chevron Pipeline. In addition, SECOR will review the records to determine the type of fuel <br /> that has been pumped through the pipeline and when it was pumped. <br /> UTILITY MAP PREPARATION <br /> SECOR will meet with a private utility locator to locate all utilities along West Grant Line <br /> Road. In addition, a map will be prepared depicting the location of all utilities found. <br /> I:\Chevron\32792\Reports\2004 Chevron Pipeline Characterization Work Plan.doc <br />
