Improving EPA’s Latest Ozone Transport Rule

Acoel

The agency’s air quality modeling indicates that most areas would receive an ozone reduction of less than 0.1 These air quality impacts are minimal compared with the major ozone reductions resulting from the 1998 SIP Call, which resulted in more than 80,000 megawatts of coal capacity being retrofitted with SCRs. ppb by 2025.

CLEAN AIR ACT COST BENEFIT ANALYSIS IS REQUIRED ONLY WHEN AUTHORIZED BY STATUTE, EXCEPT IF IT IS IMPOSED BY EXECUTIVE ORDER, BUT COST BENEFIT ANALYSIS IMPOSED BY EXECUTIVE ORDER CAN ONLY BE MODIFIED AS DIRECTED BY STATUTE
