Consistent with the EPA Administrator’s regulatory agenda announcement in March 2025, the EPA proposes to restructure the Regional Haze Program rule (40 CFR Part 51 Subpart P). This rulemaking is expected to focus on future regional haze planning obligations for states. The rule restructuring effort will ensure that it fulfills Congressional intent, is based on current scientific and technical information, and reflects recent improvements in air quality.
