Ms. Natalia Subbotnikova, REHS October 24, 2023 Page 3 the San Joaquin Valley Air Pollution Control District (SJVAPCD). The proposed well installation will not involve drilling directly through known in-place asbestos,therefore additional permitting documents will not need to be filed with SJVAPCD. HEALTH AND SAFETY CONSIDERATIONS Work on or near landfill sites warrants special precautions to mitigate potential combustible gas hazards, worker exposure to the trace constituents of LFG, or exposure to physical hazards that may be encountered. The LFG extraction wells are large diameter wells and shall be barricaded and/or covered until completed with the top soil layer installed. If personnel need to be within ten feet of an open borehole, a lanyard system tied to an immovable object, or similar system as outlined in the health and safety plan (HASP), shall be used to prevent accidental falls. Every attempt shall be made to complete each well prior to leaving the site to help mitigate the potential risks and emissions associated with incomplete well borings. A HASP for the well installation activities is prepared prior to beginning the work. The HASP describes potential hazards and outlines site-specific protection, monitoring and record keeping provisions. The Contractor's HASP will be provided once available, which will also include an asbestos mitigation plan to address health and safety procedures that must be followed during drilling in the asbestos areas. Additional precautions will be taken to ensure contractors and CQA personnel are prepared should asbestos be encountered. The "Asbestos Containing Waste Management, Forward Landfill" memorandum prepared by Forward Landfill, Inc. and submitted to the SJCEHD on February 13, 2003, is available at the site and can be provided upon request. At a minimum, when asbestos is encountered it will be immediately sprayed down with water, placed in a pile separate from the other drill spoils, placed in a haul truck and kept moist, and then disposed of in an area specified by Forward Operations Manager for tracking of the relocated asbestos. CQA personnel will not be performing logging or temperature readings on any asbestos containing drilling spoils. REPORTING An installation report that documents the drilling activities and well completion details will be prepared for submittal to Republic. Boring logs and well completion diagrams will be submitted as part of the installation report. All reports will be prepared by or under the supervision of a California Professional Geologist or Professional Engineer. FORWARD 2023 LFG SJCEHD WORK PLAN
