Mr. Robert McClellan October 1 , 2010 Page 8 The Forward Landfill lies near the Stockton Municipal airport and therefore, Federal Aviation Administration (FAA) clearance must be obtained prior to the start of drilling activities. All appropriate paperwork and notices shall be filed with the FAA and the Stockton Municipal airport prior to work beginning. All proposed probe locations will be located and marked using a Global Positioning System (GPS) instrument prior to drilling activities to ensure the final probe locations meet the 1,000- foot spacing requirement, and to obtain accurate elevations. Probe depths will be adjusted, as necessary, based on the elevations obtained by GPS. 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 when open. If personnel need to be within 10 feet of an open borehole, a lanyard system tied to an immovable object shall be used to prevent accidental falls. Every attempt shall be made to complete each well prior to leaving the site so that no unattended boreholes are present. A health and safety (H&S)plan for the well installation activities will be prepared prior to beginning the work. The H&S plan will describe potential hazards and will outline site-specific protection, monitoring and record keeping provisions. REPORTING An installation and evaluation report that documents the LFG extraction and SVE well installation and the evaluation monitoring will be submitted to the LEA. An installation report that documents the drilling activities, final LFG probes, and well completion details will also be prepared for submittal to Forward, Inc. 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 Engineer. IMPLEMENTATION SCHEDULE The new LFG extraction and SVE wells will be installed as soon as Forward can obtain approvals and the necessary permits. The following is a proposed schedule for the installation, but is contingent on the Work Plan review and approval turn around time.
