Locating and Estimating (L&E) Documents

This report series, titled Locating and Estimating Air Toxic Emissions from Sources of (source category or substance) characterizes the source categories for which emissions of a toxic substance have been identified. These volumes include general descriptions of the emitting processes, identifying potential release points and emission factors. AP 42, Compilation of Air Pollutant Emission Factors and the WebFIRE database should be checked for more current emission factors.
