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.

EPA’s Cross-State Air Pollution Rule Will Have A Dramatic Impact on Texas and Louisiana

The Energy Law Blog

Emissions reductions will take effect quickly, starting January 1, 2012 for SO2 and annual NOx reductions, and May 1, 2012 for ozone season (May-September) NOx reductions. Texas power plants must meet the January 1, 2012 deadline for SO2 and annual NOx emissions, and the May 1 deadline for ozone season NOx emissions.
