EPA Updates Guideline on Air Quality Models
On December 20, 2016, the U.S. EPA Administrator signed a final rule entitled Revisions to the Guideline on Air Quality Models: Enhancements to the AERMOD Dispersion Modeling System and Incorporation of Approaches to Address Ozone and Fine Particulate Matter. The rule provides EPA-recommended models and other techniques as well as guidance for their use in predicting ambient concentrations of air pollutants. EPA's finalized changes 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 make various editorial improvements. The Federal Register version of the Final Rule is available here. The rule, referred to hereafter as the 2017 Guideline, was published on January 17, 2017, and takes effect on March 21, 2017.
