DEQ recently released the draft SO2 Annual Report for public review and comment. The report summarizes annual SO2 emissions from five applicable sources in counties that were designated as attainment/unclassifiable for the 2010 primary SO2 NAAQS based on modeling submitted to EPA by DEQ. In the report, DEQ recommends no additional modeling or analysis of these sources at this time. The draft report is available on DEQ's website and comments must be submitted by June 29, 2018.
