EPA Backs Kentucky's Plan to Cut Sulfur Dioxide Emissions
Published Date: 9/5/2025
Proposed Rule
Summary
The EPA is set to approve Kentucky’s plan to track and control sulfur dioxide pollution in the Henderson-Webster area. This means new rules will help keep the air cleaner by making sure new factories follow stricter limits. These changes affect local businesses and aim to protect the community’s health without extra costs right now.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 0 costs, 1 mixed.
Stricter Permits for New Sources
The EPA is proposing to approve Kentucky’s plan submitted January 26, 2024 and February 15, 2024 that certifies the nonattainment new source review (NNSR) requirement for the Henderson‑Webster 2010 1‑hour sulfur dioxide (SO2) nonattainment area. This means new or expanded industrial sources in the Henderson‑Webster area will be subject to NNSR permitting and related requirements under the Clean Air Act for the 2010 1‑hour SO2 NAAQS.
Base‑Year Emissions Inventory Certified
Kentucky’s SIP revisions certify the base year emissions inventory requirement for the Henderson‑Webster 2010 1‑hour SO2 nonattainment area. This establishes the official emissions counts for that area to support air quality planning and tracking under the Clean Air Act.
