USEPA`s AP-42, emission factor reference manual lists 27 hazardous air pollutants that have been determined to be present in gas generated at landfills. Different AP-42 values are given for some air toxic compounds generated from municipal solid waste, industrial waste, and hazardous waste. This paper compares data compiled from five landfill gas sampling projects in parts per million with the AP-42 data. The sampling took place at landfills containing municipal solid waste and non-hazardous industrial waste. Sampling was performed according to the Tier 2 testing procedures for total non-methane organic compound concentrations described in the New Source Performance Standards Subpart WWW for Municipal Solid Waste Landfills. The speciation analysis was conducted by EPA Method TO-14. The list of TO-14 compounds for the speciation analysis was extended to include, at a minimum, all 27 AP-42 listed hazardous air pollutant compounds. The landfills included sites from across the country. The paper describes data quality and the effect of landfill age on some individual air toxic concentrations. The author also comments on the agreement between the total non-methane organic compound concentration and the total molecular weight equivalent concentration of the individual compound concentrations. In general, the concentration values were similar for the AP-42 compounds, although several AP-42 compounds were not detected.
