State Budgets under the Good Neighbor Plan for the 2015 Ozone NAAQS

For the 22 states linked to downwind air quality problems with EGUs covered under this action, EPA issued new or amended Federal Implementation Plans (FIPs) to establish state emissions budgets to reflect additional emission reductions from electric generating units (EGUs) beginning with the 2023 ozone season. To incentivize ongoing operation of identified emission controls to address significant contribution, EPA will also dynamically adjust these states’ emission budgets for each ozone season 2026 and thereafter. As such, the table includes emission budgets for each state for each ozone season for 2023 through 2025, and preset budgets for 2026 through 2029. For 2030 and beyond, EPA solely uses the dynamic budget process.

Note: In the event this final rule becomes effective after May 1, 2023, the emissions budgets and assurance levels for the 2023 control period will be adjusted under the rule’s transitional provisions to ensure that the increased stringency of the new budgets would apply only after the rule’s effective date. The 2023 budget amounts shown in this table do not reflect these possible adjustments. For more information, see the Prorating Emissions Budgets, Assurance Levels, and Unit-Level Allowance Allocations in the Event of an Effective Date After May 1, 2023 (pdf) (200.38 KB, June 8, 2023) factsheet and the discussion of the transitional provisions in Section VI.B.12 of the final rule preamble.
