7.5.3 GAS CONDENSATE COLLECTION SYSTEM <br /> As landfill gas cools within LFGES piping, condensate is formed. Condensate <br /> generation is dependent upon gas flow and variations in ambient temperatures. <br /> Along with the LFGES, a condensate management system will be designed to <br /> handle condensate that collects in the low points of the LFGES piping. Sump <br /> pump stations will be utilized to transfer condensate from these low points to a <br /> holding tank located at the flare station. The holding tank(s) can be emptied <br /> when full and the condensate will be treated or disposed of at an appropriate <br /> facility. An alternative process that could be implemented is the development <br /> and installation of a condensate injection system to incinerate collected liquids in <br /> the flare stack. <br /> 7.5.4 LANDFILL GAS MONITORING <br /> The purpose of a rigorous monitoring program is to evaluate the effectiveness of <br /> the LFGES and to adjust the system as necessary for efficient and effective <br /> collection of LFG. Recommended sampling activities to be performed at the <br /> Forward Landfill are as follows: <br /> Monitoring/Sampling Initial Frequency <br /> • Instantaneous Surface Monitoring Quarterly <br /> • Perimeter Probe Sampling Quarterly <br /> • Gas Extraction System Sampling Bi-Monthly <br /> • Wind Speed and Direction Monitoring Periodic <br /> • Gas Treatment Facility Source Testing Annual <br /> The main office trailer and maintenance building are also monitored to assess <br /> potential gas accumulations at the foundations. <br /> To verify landfill gas control, landfill gas monitoring shall conform to the <br /> requirements of Title V and NSPS, as implemented by the San Joaquin Valley <br /> Air Pollution Control District. In addition, landfill gas monitoring shall conform <br /> to any other applicable San Joaquin Valley Air Pollution Control District <br /> regulations and requirements, as well as applicable regulations and <br /> requirements of CIWMB, RWQCB and other appropriate regulatory agencies. <br /> Forward Landfill JTD 7-13 <br /> L:\Allied\2000.193\Reports\td:Sec-7.0:05/24/02 <br /> BRYAN A.STIRRAT S.ASSOCIATES <br />
