February 7, 2012 - Final Revisions Rule and Direct Final Rule

EPA issued two sets of minor adjustments to the Cross-State Air Pollution Rule (CSAPR). These final rules maintain the significant health benefits of CSAPR, while making minor technical adjustments based on the latest and best data to ensure a smooth transition for utilities. The adjustments provide flexibility to states by increasing budgets in seventeen states and easing limits on market-based compliance options.

Final Revisions Rule

The final revisions rule will enhance compliance flexibility and smooth the transition from the Clean Air Interstate Rule (CAIR) programs to the CSAPR programs.

October 6, 2011 - Proposed Technical Adjustments

EPA proposed technical adjustments to the final Cross-State Air Pollution Rule (CSAPR). CSAPR is a sound, achievable, market-based program that will deliver strong public health protections. No changes are being proposed or contemplated to the core elements of the program. The proposed revisions will not affect the significant air quality improvements slated to occur under CSAPR, nor have a major impact on CSAPR's goal to reduce interstate transport of pollution to help downwind states in their efforts to attain and maintain the National Ambient Air Quality Standards (NAAQS).
