What the agency says
The Environmental Protection Agency (EPA) is taking interim final action to adjust the Revised Cross-State Air Pollution Rule (CSAPR) Update "budget" for nitrogen oxides (NO<INF>X</INF>) emissions from Indiana electricity generating units (EGUs) during the May-September "ozone season" for 2024 and subsequent years. Relatedly, EPA is also adjusting the default unit-level allocations of emission allowances to Indiana EGUs for 2024 and subsequent years in accordance with the adjustments to the state emissions budget. When originally establishing state emissions budgets and default unit-level allocations for 2024 and subsequent years in the Revised CSAPR Update rulemaking, EPA relied in part on announcements from EGU owners regarding their plans to retire certain EGUs before the 2024 ozone season. The purpose of the adjustments being made in this action is to account for the subsequent decisions by some EGU owners to defer or cancel the previously announced retirement plans.
