activities , frequency of inspection and maintenance work , and emergency procedures are set forth in the 0&M manual . Routine activities include pump station component inspection and main- tenance, probe testing and data assessment, well field monitoring and periodic adjustments , site inspections for settlement and repairs , and routine preparation and submittal of monitoring and certification reports to local enforcement agencies . System . shutdown sounds an alarm that requires restarting the system to silence . Continuous operation of active gas control facilities re- quires routine maintenance of pump station mechanical compo- nents . Oil levels for extraction blowers and motors are main- tained and periodically changed (ev-ery 2,000 hours ) . Belt tension is checked and fan belts replaced , as required . Extraction blowers , motors, automatic valves , and continuous flow and pressure-sensing equipment are routinely inspected to ensure proper operation. Replacement of worn bearings , seals , "0" rings , etc . , are carried out , as necessary. Extraction blow- er flow rates and pressures/vacuums are monitored and adjusted (one to two times per month) to ensure that the blower operates within acceptable ranges , as specified by the manufacturer, and LFG control meets requirements . The ground flare requires periodic maintenance to ensure that the LFG undergoes combustion according to design specifica- tions . Burner combustion ports are re-bored and cleaned ; auto- matic valves and sensors are checked ; and the ignition system ( including automatic pilot light , fuel lines , and propane storage tank ) is tested, and worn components replaced, as necessary. Pump station electrical panel components are checked for proper operation of panel lights, alarm signals, timers , auto- matic shut-off valves , etc . Corrective work is conducted by the flare manufacturer or an electrical subcontractor. Subslab and off-site monitoring probes are tested for meth- ane gas to verify performance of the LFG control system. Testing is conducted once per month (more frequently during system down- time) , and results are recorded and maintained with a location map for future reference and/or submittal to the owner and local regulatory agency. Reports are routinely prepared and submitted to the owner to provide updated information on site conditions and control system status . Reports are generally prepared monthly or quarterly, as specified in the approved design report for the particular site. Reporting frequency is increased whenever corrective work on the control system is required. Adjustment of the extraction well field (to maintain optimum LFG control with minimum air intrusion into the landfill ) is based on monitoring probe data , as well as LFG composition , flow LFG-73
