🚗Delaware's EPA Proposal for Vehicle Emissions Inspection Program
The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the State of Delaware. This SIP revision addresses Clean Air Act (CAA) requirements for the enactment of a Basic vehicle emissions inspection and maintenance (I/M) program for the Delaware portion (i.e., New Castle County) of the Philadelphia-Wilmington-Atlantic City, Pa-NJ-MD- DE Nonattainment Area (Philadelphia NAA) for the 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS).

Learn More⚡Adjusted Emissions Budgets for Indiana Under CSAPR
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.

Learn More🚗EPA Finds Emissions Budgets Adequate for Fairbanks Transportation
The Environmental Protection Agency (EPA) is notifying the public that we have found the motor vehicle emissions budgets adequate for transportation conformity purposes for the Fairbanks North Star Borough's 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) nonattainment area. The budgets were submitted on December 4, 2024, as part of Alaska's state implementation plan revisions (Fairbanks Revised 189(d) Plan). As a result of our finding, these budgets must be used when determining conformity of the Fairbanks transportation plan and transportation improvement program.

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Missouri State Implementation Plan (SIP) related to the control of emissions during petroleum liquid storage, loading and transfer in the Kansas City metropolitan area. The revisions to this rule include adding incorporations by reference to other state rules, adding definitions specific to the rule, revising unnecessarily restrictive or duplicative language, and making administrative wording changes. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's proposed approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).

EPA is proposing approval of the following Clean Air Act (CAA) SIP elements: The attainment demonstration for the SO<INF>2</INF> NAAQS, which includes an Agreed Order on Consent (AOC) for the Cabot Corporation's Ville Platte Plant (Cabot) facility; the reasonable further progress (RFP) plan; the reasonably available control measures (RACM) and reasonably available control technology (RACT) demonstration; the emission inventories; and the contingency measures. The State has demonstrated that its current Nonattainment New Source Review (NNSR) program covers this NAAQS; therefore, no revision to the SIP is required for the NNSR element.
