Connecticut's 2017 pollution stats get EPA thumbs-up

Published Date: 4/7/2025

Proposed Rule

Summary

The EPA is proposing to approve Connecticut’s plan that updates pollution data from 2017 to help meet cleaner air goals for ozone pollution. This affects people living in Greater Connecticut and nearby areas struggling with ozone smog. Comments on this plan are open until May 7, 2025, and the update helps guide future pollution controls without immediate costs.

Analyzed Economic Effects

3 provisions identified: 3 benefits, 0 costs, 0 mixed.

Areas reclassified to Serious with 2027 deadline

EPA has reclassified the Greater Connecticut area and the Connecticut portion of the NY-NJ-CT area to Serious nonattainment for the 2015 8-hour ozone standard. Serious areas must attain the 2015 ozone NAAQS as expeditiously as practicable but no later than August 3, 2027.

EPA proposes approval of CT 2017 emissions inventory

You live in Greater Connecticut or the Connecticut part of the NY-NJ-CT area: EPA is proposing to approve Connecticut’s 2017 base year emissions inventory for the 2015 8-hour ozone standard for those areas. Comments on this proposed approval are due by May 7, 2025, and EPA says the approval helps guide future pollution controls while not imposing immediate costs or additional federal requirements beyond state law.

EPA approval adds no new federal burdens

EPA says this proposed approval merely accepts Connecticut law as meeting Clean Air Act requirements and does not impose additional federal requirements, does not create significant economic impacts on a substantial number of small entities, and does not add information-collection burdens. The proposed action is therefore presented as not creating new federal costs for businesses or taxpayers.
