Please join SWEP Rocky Mountain Chapter to a speaker event on Wednesday October 2nd, which will feature Ms. Sara Lubchenco from Tetra Tech presenting “DMNFR Ozone Nonattainment Area – Reclassification to “Serious” for the 2008 8-hour Ozone NAAQS”. The current, enforceable 8-hour Ozone National Ambient Air Quality Standard (NAAQS) is 75 parts per billion (ppb). Under the 2008 Ozone Standard, the EPA reclassified the Denver Ozone Nonattainment area from “marginal” to “moderate” in the Spring of 2016. The region was given a deadline of July 12, 2018 to attain with the 2008 Ozone Standard but was granted a one year “clean year” extension after petitioning the EPA to exclude emission monitor data correlated to wildfire events which met the EPA definition of “exceptional”. The Governor’s Office repealed the clean year extension request and the region is currently facing an impending reclassification to “serious” nonattainment. The current major source threshold for VOC and NOx (ozone forming precursors) is 100 ton per year (TPY). A serious reclassification will reduce the major source permitting threshold to 50 TPY. This means that the facilities operating as a minor source (i.e., emissions between 50 TPY and 99 TPY) will now be required to obtain a Title V Permit.

The event will be held at Pinyon Environmental, Inc., 3222 S. Vance St, Unit 200. Lakewood, CO 80227  in the Lower Level Conference Room

Check-in opens at 11:30 a.m. The event runs from 12:00 to 1:00 p.m. with a catered lunch ($20 for SWEP members and $25 non-SWEP members, cash or check at check-in).
