On October 15, 2020, EPA proposed the Revised Cross-State Air Pollution Rule (CSAPR) Update to fully address 21 states’ outstanding interstate pollution transport obligations for the 2008 ozone National Ambient Air Quality Standards (NAAQS). Starting in the 2021 ozone season, the proposed rule would require additional emissions reductions of nitrogen oxides (NOX) from power plants in 12 states, improving air quality for millions of Americans.
EPA proposed to issue new or amended Federal Implementation Plans (FIPs) to revise emission budgets in 12 states to address air quality impacts of the interstate transport of ozone air pollution.
