Connecticut firms face clearer permit rules
If you operate a factory or other stationary source in Connecticut’s nonattainment areas, the EPA has approved state rule changes clarifying when you must get a New Source Review (NSR) permit. The state changes (RCSA 22a-174-3a revisions) are federally enforceable as of May 4, 2026, and the rule says no new fees or costs are expected right now, though businesses should prepare for clearer applicability and references to the state's significant emission rate thresholds (Table 3a(k)-1).
Rule does not apply on Indian reservations
The EPA approval does not apply on any Indian reservation land or in areas where a tribe has demonstrated jurisdiction. In those areas, the rule will not impose substantial direct costs on tribal governments and the SIP is not approved to apply.
