2/5 Pre-Field Activities Permitting URS will obtain the necessary drilling and well destruction permits from the San Joaquin County Environmental Health Department prior to well abandonment activities. Health and Safety Plan A Site-specific health and safety plan (HASP) will be created to establish prudent health and safety guidelines which will minimize the risk of occupational accidents and exposure to hazardous substances associated with environmental sampling and removal activities of potentially contaminated soil, groundwater, and construction debris materials. At minimum, the HASP will include planned Site activities, Site health and safety characterization, physical, chemical, and biological hazards, characterization of waste products, hazard evaluation – including job specific tasks, and responsibilities of key personnel. Additionally, the HASP will also provide emergency incidence response guidelines and contacts in the event of an occupational accident or hazardous exposure, and the nearest hospital and occupational clinic address, phone number, and directions. Additional protocols will be addressed regarding COVID-19 safety concerns. Safety tailgate meetings will be conducted daily before work begins to review the Site hazards and the potential hazards associated with the day’s work. The HASP will comply with Title 8 of the California Code of Regulations, Federal Occupational Safety and Health Administration Code of Federal Regulations Title 29, part 1910, State and Federal regulations related to the COVID-19 pandemic. The HASP will be reviewed by field staff and contractors prior to beginning field operations at the Site. A copy of the plan will be available to field staff during field activities. Utility Clearance URS will mark the Site and notify Underground Service Alert of Northern California and Nevada (USA North 811) of the pending work at least 48 hours before fieldwork begins. URS will also utilize the services of a private geophysical locator to identify underground utilities at each well location. Well Construction Information URS reviewed available documents on the Geotracker database related to the Site in an attempt to obtain well construction information on wells MW-1 through MW-7, and MW-1R. Information on the total depth of most groundwater monitoring wells was obtained from a 2019 Groundwater Monitoring Well Installation Report, a 2019 Monitoring Summary Report and a 2021 Monitoring Report, which are documents reviewed from the GeoTracker database. Total depth and other relevant information on the groundwater monitoring wells are provided on the table below.
