Knockout pot pressure drop; <br />Air compressor outlet pressure. <br />Based on monitoring data at the blower/flare station, adjustments will be made to increase or <br />decrease flow to maintain gas quality and provide vacuum to the gas collection system. <br />SCS -FS has developed a site-specific preventative maintenance checklist that will be completed by <br />the field technician during each scheduled site visit and at the pre -determined frequency intervals. <br />The preventative maintenance checklist records will be kept on site and included in the monthly <br />0&M reports as applicable. Manufacturer recommended preventative maintenance documents and <br />checklists are included for your reference as Appendix A. <br />LFG Extraction System <br />System components will be observed for proper operation. Minor problems such as damaged or <br />deteriorated monitoring ports will be replaced during the check. Major problems will be relayed to <br />Republic immediately. At each extraction point, we will measure (and/or observe) and record: <br />• LFG flow (where possible); <br />• LFG composition (methane, carbon dioxide, oxygen, and balance gas). <br />• Wellhead gas pressure. <br />• Wellhead gas temperature. <br />• Well head piping and well bore seal condition at the landfill surface will be noted; <br />• Inspect the cover integrity of the landfill and note it in the daily logs. <br />In conjunction with the extraction well monitoring, adjustments will be made at each well as required <br />to maintain odor control, and system balance/methane composition. <br />TASK 2 - REPORTING <br />SCS -FS will submit an 0&M report summarizing routine and non -routine, if applicable, activities that <br />were performed during the preceding month. The 0&M report will contain the following monitoring <br />and maintenance records: <br />• Wellfield monitoring results (two rounds of data per month); <br />• Six month rolling wellfield monitoring results; <br />• Bi -weekly GCCS checklist; <br />• Flare Station preventative maintenance checklist; <br />• Rolling twelve month condensate sump pump counter data; <br />• Recommended GCCS Repairs; <br />• Semi-annual pump maintenance summary; <br />• Semi-annual liquid level data; <br />• Quarterly air compressor work logs (provided by sub -contractor). <br />Indian River Landfill O&M Proposal Page 3 www.scsengineers.com <br />
