Publication Summary

The purpose of the original document, Air Toxics Emissions Estimation Methods Evaluation, was to establish sound methods for estimating air toxic emissions. These methods would be used to develop emission inventories to support rule development, the operating permit and registration programs, and other studies. In this revision, the purpose expands to include process descriptions, variables, current control equipment, Reasonable Available Control Technology (RACT) and Maximum Available Control Technology (MACT) standards. The report should be looked at as a starting point for air toxics information, and the references at the end of each chapter can be used for more detailed information. While the original document also touched on criteria pollutants, this document will focus its efforts on air toxics, specifically those listed in Chapter 173-460 WAC.
