Analyzed Economic Effects
3 provisions identified: 3 benefits, 0 costs, 0 mixed.
Clearer Permit Rules for Connecticut Sources
Connecticut changed its New Source Review permit rules to make it clearer when major stationary sources (factories and similar facilities) in nonattainment areas must get permits. The state changes were adopted March 14, 2024 and the EPA is proposing to approve Connecticut's October 3, 2024 submittal; EPA says these clarifications do not change applicability thresholds, offset obligations, or control technology requirements.
Public Health and Environment Protected
EPA says the changes clarify when permit requirements apply in areas that do not meet air quality standards, which helps protect the environment and public health. EPA is proposing approval and is accepting public comments until December 29, 2025.
No Added Costs to Small Entities
EPA states this proposed approval merely approves existing state law and does not impose additional requirements beyond state law. The action is certified as not having a significant economic impact on a substantial number of small entities.
