Evaluation of Fugitive Emissions Using Ground-Based Optical Remote Sensing Technology
(111 pp, 2070 Kb)
February 2007


EPA has developed and evaluated a method for characterizing fugitive emissions from large area sources. The method, known as radial plume mapping (RPM), uses multiple-beam, scanning, optical remote sensing (ORS) instrumentation such as open-path Fourier transform infrared spectroscopy, ultraviolet differential absorption spectroscopy, open-path tunable diode spectroscopy, and open-path tunable diode laser absorption spectroscopy in unique radial configurations and optimization algorithms providing essential spatial data for emission calculations. The RPM method can be used for characterizing emissions from a wide range of area sources, including landfills, wastewater treatment plants, and agricultural operations. This report represents a three-year effort conducted to evaluate the feasibility of using ORS instrumentation to measure landfill gas emissions, which include methane, volatile organic compounds, and air toxics.
