l <br /> 2.1 MONTHLY(LFG CONTROL SYSTEM) <br /> 2.1.A Operation r <br /> F <br /> The contractor adjusts the LFG extraction wells as needed to maintain methane <br /> content below five percent(5%)by volume at the migration monitoring wells and <br /> surface emissions below 1000 parts per million. The flow rate and methane t <br /> content of the gas delivered to the flare.is recorded, and the BTU loading rate <br /> calculated to verify that the flare is operating within the AQMD permit conditions. <br /> Condensate handling systems shall be checked for proper operation and the total <br /> condensate volume destroyed is recorded. <br /> { <br /> E <br /> 2.1.13 Monitoring <br /> The contractor will monitor the flare station as well as the LFG extraction wells. <br /> Monitored parameters include: <br /> Flare Station: I <br /> s <br /> 1 Date, time, and name of monitoring personnel. <br /> 2 Meteorological conditions (e.g.,wind direction and velocity, barometric . <br /> pressure, ambient temperature,general weather observations, etc.) <br /> 3 Methane, oxygen and carbon dioxide gas concentrations <br /> 4 Total LFG flow rate <br /> 5 Methane content <br /> 6 Blower inlet/outlet pressure and temperatures I <br /> 7 Flare exit gas temperature <br /> 8 Carbon monoxide concentrations shall be measured by Draeger tube <br /> 9 Other data and maintenance items as identified on County's.Monthly <br /> checklist. <br /> LFG Extraction Wells: <br /> i <br /> 1 Date, time, and name of monitoring personnel <br /> 2 Meteorological conditions (e.g.,wind direction and velocity, barometric i <br /> pressure, ambient temperature, general weather observations,etc.) <br /> 3 Methane, oxygen and carbon dioxide gas concentrations <br /> 4 Wellhead/header pressure and flow rate (where applicable) <br /> 5 LFG temperature <br /> 6 The contractor will observe the LFGCCS blowers,flame arrester,flare, <br /> control panel, data recording devices,well field, and condensate drain, <br /> sumps, and pumping systems for the following: <br /> 7 Proper operation <br /> 8 Accessibility <br /> 9 Vandalism <br /> 10 Malfunctions <br /> 11 Leaks <br /> LFG Operation And Maintenance Pan San Joaquin County <br /> Corral Hollow Sanitary Landfill 7 Public Works Department <br /> March 31,2008 Solid Waste Division <br />
