• EPA approves Georgia air quality plan removing nonattainment new source review requirements — The Environmental Protection Agency finalized approval of Georgia's State Implementation Plan revision removing nonattainment new source review (NNSR) permitting requirements and emission reduction credit provisions from the state's air quality regulations. The revision follows Georgia's 2022 redesignation of the Atlanta ozone area from nonattainment to attainment status under the Clean Air Act. The EPA rejected arguments that NNSR should remain as a contingency measure despite recent ozone standard exceedances, finding that Prevention of Significant Deterioration (PSD) permitting and maintenance plan triggers provide adequate protection.
• EPA approves Kentucky's Limited Maintenance Plan for Louisville Area ozone standards — The Environmental Protection Agency finalized approval of Kentucky's Limited Maintenance Plan (LMP) for the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) covering the Kentucky portion of the bi-state Louisville Area (Bullitt, Jefferson, and Oldham Counties). The plan demonstrates that air quality will remain in attainment through 2027, the end of the second 10-year maintenance period following the area's 2007 redesignation from nonattainment to attainment. The EPA evaluated design value data, monitoring networks, and contingency provisions, and determined the plan adequately assures maintenance of the standard. The approval makes the plan's commitments federally enforceable under the Clean Air Act.
• EPA approves Maryland air plan revisions establishing nitrogen oxide emission limits for municipal waste combustors — The Environmental Protection Agency finalized approval of Maryland's State Implementation Plan revisions establishing reasonably available control technology (RACT) requirements for nitrogen oxide emissions from municipal waste combustors. The rule sets specific emission limits for two large facilities—Montgomery County Resource Recovery Facility (140 ppmv 24-hour average, 105 ppmv 30-day average) and Wheelabrator Baltimore (150 ppmv 24-hour average, 145 ppmv 30-day average)—and exempts small combustors constructed before August 30, 1999. The EPA rejected a commenter's request for stricter limits, finding Maryland's determinations adequate under the Clean Air Act.
• EPA approves Missouri air quality rule revisions on construction permit exemptions — The Environmental Protection Agency finalized approval of Missouri's State Implementation Plan revision modifying construction permit exemptions under the Minor New Source Review program. The rule refines emergency generator exemptions, updates recordkeeping requirements, and clarifies cross-references. EPA found the revisions comply with the Clean Air Act, do not backslide air quality, and strengthen permit exemption standards. The rule becomes effective November 9, 2026.
• EPA approves New Jersey State Implementation Plan revisions for ozone RACT certifications under Clean Air Act sections 182 and 184. — The Environmental Protection Agency issued a final rule approving New Jersey's State Implementation Plan (SIP) revisions submitted November 23, 2021, and March 3, 2025, certifying that the state meets Reasonably Available Control Technology (RACT) requirements for volatile organic compounds and nitrogen oxides emissions under the 2008 and 2015 ozone National Ambient Air Quality Standards. The approval covers the New York-Northern New Jersey-Long Island nonattainment area (Serious classification for 2008 ozone; Moderate for 2015) and the Philadelphia-Atlantic City nonattainment area (Moderate for 2015), as well as statewide Ozone Transport Region obligations. The rule becomes effective November 9, 2026.
• EPA approves Oklahoma air plan for interstate SO2 transport requirements under Clean Air Act — The Environmental Protection Agency issued a final rule approving portions of Oklahoma's State Implementation Plan (SIP) submitted May 28, 2021, demonstrating compliance with Clean Air Act section 110(a)(2)(D)(i)(I) interstate transport requirements for the 2010 1-hour sulfur dioxide (SO2) National Ambient Air Quality Standard (NAAQS). EPA determined Oklahoma's emissions will not significantly contribute to nonattainment or interfere with maintenance of the SO2 NAAQS in other states, based on weight-of-evidence analysis including certified design values, emissions trends, and source-specific evaluations within a 50-kilometer urban-scale assessment. The rule becomes effective November 9, 2026, and applies to certain areas of Indian country in Oklahoma consistent with prior SAFETEA approval and D.C. Circuit precedent.
• EPA approves clean data determination for Berrien and Muskegon County ozone nonattainment areas — The Environmental Protection Agency finalized a determination that Berrien County and Muskegon County, Michigan have attained the 2015 ozone National Ambient Air Quality Standards based on 2023-2025 monitoring data and approved exceptional events exclusions for wildfire smoke impacts. The determination suspends requirements for these areas to submit attainment demonstrations, Reasonably Available Control Measures plans, Reasonable Further Progress plans, and other State Implementation Plan requirements related to ozone attainment, contingent on continued compliance with the standard.
• EPA publishes weekly Environmental Impact Statements notice — The Environmental Protection Agency published a notice of availability for Environmental Impact Statements filed between September 28 and October 5, 2026, pursuant to Clean Air Act Section 309(a) and CEQ guidance. The notice lists two EIS actions: a draft Nuclear Regulatory Commission combined license application for the Project Matador Advanced Energy and Intelligence Campus in Texas (comment period ending November 23, 2026), and an amended APHIS draft grizzly bear damage management EIS for Montana with an extended comment period (now ending November 4, 2026). EPA's comment letters on EISs are available through the EPA's CDX database.

• US Supreme Court hears arguments in Suncor Energy v. Boulder County climate liability case — The US Supreme Court began oral arguments on October 5, 2026, in Suncor Energy Inc v County Commissioners of Boulder County, a case in which fossil fuel companies Suncor Energy and ExxonMobil seek to block state-level climate damage lawsuits. Boulder County officials sued the companies in Colorado state court in 2018 to recover costs of climate-related disasters. The oil companies argue federal law pre-empts state court jurisdiction; Boulder argues the Constitution permits state climate litigation. A ruling is expected in summer 2027. The case could affect dozens of similar climate suits nationwide.
