Complimentary Webinar - Regional Haze 2nd Planning Period in the WRAP Region & What it Means for Your Facility - Part 1: General Overview

The Clean Air Act (CAA) tasks EPA with returning our national forests and parks (Class I areas) to natural visibility conditions.  Visibility impairment is produced by sources and activities which emit fine particles and their precursors (such as SO2 and NOx).  The EPA and states have already gone through the 1st Planning Period Regional Haze regulations and are about to embark on the second.

Western state agencies, with the help of the Western Regional Air Partnership (WRAP), have begun work on this second phase which includes examining all sources regardless of type and potential impacts on visibility. Many states are looking to finalize the rule by mid-2020. This webinar series will discuss the 2nd Planning Period will impact sources including non-major sources. The presentation covers which sources may now be subject to Regional Haze, explain how photochemical modeling models will be used differently than the CALPUFF model that was used in the 1st Planning Period, review source apportionment models such as PSAT/SCICHEM, and discuss timelines.
