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.

Good News—and Bad—about Fossil Fuel Power Plants in 2023 

Union of Concerned Scientists

GW record from 2021. In 2021 alone, the plants slated for retirement emitted more than 28,000 tonnes of nitrogen oxides (NO x ), 32,000 tonnes of sulfur dioxide (SO 2 ), and 51 million tonnes of carbon dioxide (CO 2 ), according to EIA data. NO x also contributes to the formation of ozone (or “smog”), another toxic pollutant.
