Summary
The EPA is giving a thumbs-up to Connecticut’s updated air plan that adjusts rules because the ozone pollution level got reclassified as more serious. This means some businesses in Connecticut now have new deadlines to follow cleaner air rules starting March 30, 2026. It’s all about keeping the air fresh and safe without any surprise costs announced yet.

Connecticut Businesses Get New NOX Deadlines
If you operate a facility in Connecticut that was newly brought under the state's "severe non-attainment area for ozone" definition, the EPA approved revisions to RCSA sections 22a-174-22e and 22a-174-22f that add compliance dates for those sources. The state rules were adopted November 13, 2023, the new definition was approved into the SIP on February 12, 2024, and the EPA made these revisions federally enforceable effective March 30, 2026.
