On April 18, 2024, the Board proposed first-notice amendments to update its air pollution rules on permitting for the construction and modification of major stationary sources in non-attainment areas. The changes will make the Board’s Non-Attainment New Source Review (NA NSR) permitting rules consistent with the federal Clean Air Act and the United States Environmental Protection Agency’s underlying NA NSR permitting program. The Board also proposed related changes to its rules on Prevention of Significant Deterioration (PSD) permitting, as well as its rules on toxic air contaminants.
