RuleEnvironmental Protection Agency
The U.S. Environmental Protection Agency (EPA) is approving a portion of Indiana's State Implementation Plan (SIP) submission regarding the infrastructure requirements in Clean Air Act (CAA) section 110 for the 2015 ozone National Ambient Air Quality Standards (NAAQS). The infrastructure requirements are designed to ensure that the structural components of each State's air quality management program are adequate to meet the State's responsibilities under the CAA. The EPA finds that Indiana's infrastructure submission fulfills CAA requirements for a State's SIP to contain adequate provisions prohibiting emissions that will interfere with required visibility protection measures in any other State's SIP. The EPA proposed to approve this action on April 10, 2026, and received no adverse comments.

The Environmental Protection Agency (EPA or the Agency) is approving a State Implementation Plan (SIP) submitted by the State of New York for purpose of demonstrating that the State satisfies the interstate transport requirements, also known as the "good neighbor" provision of the Clean Air Act (CAA), for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) primary National Ambient Air Quality Standard (NAAQS). Under the good neighbor provision, each State's implementation plan must contain adequate provisions prohibiting the interstate transport of air pollution in amounts that will either contribute significantly to nonattainment, or interfere with maintenance, of the NAAQS in any other State. This action is being taken in accordance with the requirements of the Clean Air Act.

Proposed RuleSIGNIFICANT · E.O. 12866Defense DepartmentEngineers CorpsEnvironmental Protection Agency
The purpose of this supplemental notice of proposed rulemaking is for the U.S. Environmental Protection Agency (EPA) and the Department of the Army ("the agencies") to supplement and seek additional comment on certain aspects of an earlier proposal, published on November 20, 2025, to revise the regulations defining the scope of waters federally covered under the Clean Water Act in light of the U.S. Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. As stated in the agencies' November 20, 2025 Notice of Proposed Rulemaking (NPRM), the agencies intend for this rulemaking to provide greater regulatory certainty and increase Clean Water Act program predictability and consistency by clarifying the definition of "waters of the United States." After consideration of the public comments received on the NPRM, the agencies are issuing this notice to supplement the NPRM with additional regulatory options on certain aspects of the proposed rule.

Proposed RuleEnvironmental Protection Agency
The U.S. Environmental Protection Agency (EPA or Agency) is proposing to repeal a final rule published in the Federal Register on December 2, 2024, partially approving and partially disapproving North Dakota's 2022 regional haze State Implementation Plan (SIP) submission for the second implementation period. As a result, the EPA is proposing to approve the portions of North Dakota's 2022 SIP submission for the second implementation period that were disapproved in the EPA's 2024 partial approval/partial disapproval. In the December 2024 final rule, the EPA determined that North Dakota submitted a regional haze SIP that did not meet all the statutory and regulatory requirements for the regional haze second implementation period. On January 31, 2025, and February 6, 2025, EPA received petitions for reconsideration from the State of North Dakota, Basin Electric Power Cooperative, Lignite Energy Council (LEC), Rainbow Energy Center, and the Coyote Station Co-Owners. On January 31, 2025, the State of North Dakota, Montana-Dakota Utilities Company, NACCO Natural Resources Corporation, Basin Electric Power Cooperative, Rainbow Energy Center, and Lignite Energy Center filed petitions for review in the Eighth Circuit Court of Appeals. EPA granted reconsideration on April 30, 2025, sending letters to the State of North Dakota, Basin Electric, LEC, Rainbow Energy Center, and Coyote Station Co-Owners. The petitions for review were held in abeyance by the Eighth Circuit on June 4, 2025 pending the administrative reconsideration process.

Proposed RuleEnvironmental Protection Agency
The U.S. Environmental Protection Agency (EPA) proposes to revise a regulatory definition under the Clean Water Act (CWA) permitting regulations pertaining to discharges in the contiguous zone and ocean. The proposal would revise the regulatory definition of "discharge of a pollutant" to reflect and faithfully implement the statutory exclusion of vessels and other floating craft that add pollutants in the contiguous zone or the ocean from inclusion in the definition of "discharge of a pollutant" or "discharge", and thus, from National Pollutant Discharge Elimination System (NPDES) program requirements. The proposed rulemaking would also make conforming and clarifying changes to the NPDES regulatory exclusion for vessels and other floating craft. The effect of these changes would be that the addition of pollutants by a vessel or other floating craft in the contiguous zone or the ocean that is not secured to the seabed would not be a discharge and would not require CWA NPDES permit authorization to add pollutants to those waters.
