USE OF GLOBAL POSITIONING SYSTEM (GPS) EQUIPMENT IN LANDFILL GAS CONTROL SYSTEMS MONITORING

摘要

This paper will describe the use of the Global Positioning System (GPS) in coordination with the other instruments and procedures required by the New Source Performance Standards (NSPS) in monitoring gas surface emissions during regular surface sweeping and regulatory reporting for operating landfill gas control systems. The information to be presented is based on ongoing experience dating back 3-5 years. Refinements in GPS use at over 10 landfills through more sensitive/accurate GPS equipment, innovative uses for GPS capabilities, and advances in GPS data logging and data overlay capabilities will be described. The potential for time and cost savings through the use of GPS in landfill gas system monitoring and regulatory reporting will be discussed. Through the combination of GPS, CAD, and spreadsheets, periodic reports can be quickly and accurately prepared. Location data stored in the GPS field processor can be overlaid on CAD based survey data to provide accurate and thorough presentations of monitoring data. Data points and values can be downloaded to a spreadsheet for report tabulation and data logging. Comparisons between ground survey/manual data entry investigation and reporting, and GPS/CAD/EXCEL investigation and reporting will be discussed.
