Proposed State Budgets under the Revised Cross-State Air Pollution Rule Update
For the 12 states linked to downwind air quality problems, EPA proposes to issue new or amended Federal Implementation Plans (FIPs) to revise state emissions budgets to reflect additional emission reductions from electric generating units (EGUs) beginning with the 2021 ozone season. To incentivize ongoing operation of identified emission controls to address significant contributions, EPA also proposes to adjust these states’ emission budgets for each ozone season thereafter until such a time that air quality projections demonstrate resolution of the downwind nonattainment and/or maintenance problems for the 2008 ozone NAAQS. As such, the table includes proposed emission budgets for each state for each ozone season for 2021 through 2024.
1 Emissions projected in each state for each year in the absence of the Revised CSAPR Update proposal.
2 Each state has a variability limit of 21%, meaning they can emit up to an assurance level of 121% of the budgets shown in the tables provided that they do not collectively exceed the regional budget and any available banked allowances.
