Issues with, and suggested improvements to, Method 25C -- Determination of nonmethane organic compounds in MSW landfill gases
The US EPA issued a new sampling and test method for landfill gas with the promulgation, on March 12, 1996, of the New Source Performance Standards (NSPS) for Municipal Solid Waste (MSW) Landfills (40 CFR 60 Subparts WWW and Cc). Method 25C was developed for collecting landfill gas samples through probes driven into the waste, and then having the gas sample analyzed in a laboratory by a gas chromatograph/flame ionization detector (GC/FID) for the concentration of nonmethane organic compounds (NMOC). The NSPS require that the NMOC emission rate be calculated for landfills affected by the rule. The NMOC emission rate can be calculated with a formula in the rule, and either very conservative Tier 1 default values, or with actual site-specific NMOC concentration data collected and analyzed in accordance with Method 25C. The use of site-specific NMOC concentration data is referred to as Tier 2.
