Facility-Level Emission Changes: 2009-2022 Emissions at facilities included in this analysis either increased or decreased from 2009 to 2022, using the following criteria: • Analysis includes only coal units; • Over 75% change in emission rate; • Over 0.2 lb/mmBtu change in absolute emission rate; and • Over 1,000 ton change in emissions of SO2 or NOx. The analysis includes data submitted to EPA as of February 7, 2023. The presentation of this data is not intended to suggest the compliance status of these facilities with currently applicable federal, state, or local environmental requirements.
