Guideline on Air Quality Models
U.S. EPA’s proposed revisions to the Guideline on Air Quality Models and enhancements to the AERMOD Dispersion
Modeling System’s Incorporation of Approaches to Address Ozone and Fine Particulate Matter.
This is also
known as “Appendix W.” On July 14, 2015, the EPA Administrator signed a proposal to revise the Guideline on Air Quality Models.
The Guideline provides EPA-recommended models and other techniques, as well as guidance for their use, for predicting ambient concentrations
of air pollutants. EPA’s proposed changes would, enhance the formulation and application of the agency’s AERMOD dispersion model, prescribe
modeling techniques for secondarily formed fine particle and ozone pollution for single sources and makes various editorial improvements.
NTAA submitted comments on October 14th and the comment period on this is open until October 27th.
