No New Federal Costs for CT Businesses
EPA approved Connecticut's May 3, 2024 State Implementation Plan revisions (the 2014 and 2017 periodic emissions inventories) and states this approval "does not impose additional requirements beyond those imposed by state law". The rule is effective December 18, 2025, and EPA certified it "is not having a significant economic impact on a substantial number of small entities."
CT Fulfilled Ozone Inventory Requirement
EPA finalized approval that Connecticut's 2014 and 2017 periodic emissions inventories satisfy the Clean Air Act section 182(a)(3)(A) requirement for the 2008 8-hour ozone standard. The inventories cover volatile organic compounds (VOC) and nitrogen oxides (NOX) from point, area, non-road mobile, on-road mobile, and biogenic sources for the Connecticut portions of the NY-NJ-CT and Greater Connecticut ozone nonattainment areas.
