The Environmental Protection Agency (EPA) is taking direct final action to authorize changes California has made to its hazardous waste program under the Resource Conservation and Recovery Act, as amended. The Agency has reviewed California's application for authorization of these changes and determined that the changes satisfy all requirements.
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Mojave Desert Air Quality Management District (MDAQMD or "District") portion of the California State Implementation Plan (SIP). These revisions concern amended or rescinded prohibitory and administrative rules that regulate air pollutants under the Clean Air Act (CAA or "Act"). We are proposing to rescind numerous requirements from the District's portion of the California SIP because the requirements can be replaced by more current requirements. We are taking comments on this proposal and plan to follow with a final action.
The Environmental Protection Agency (EPA or the Agency) is correcting a typographical error in a final rule published in the Federal Register on June 17, 2025. The final rule granted a petition submitted by WRB Refining in Borger, Texas to exclude (or "delist") 7,000 cubic yards of F037 (petroleum refinery sludge) solids to be removed from their stormwater storage tanks for a one-time delisting.
Pursuant to the Solid Waste Disposal Act of 1965, as amended (commonly known as the Resource Conservation and Recovery Act (RCRA)), the Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the State of Minnesota's Underground Storage Tank (UST) program submitted by the Minnesota Pollution Control Agency. This action also codifies EPA's approval of Minnesota's state program and incorporates by reference those provisions of Minnesota's statutes and regulations that EPA has determined meet the requirements for approval. The provisions will be subject to EPA's inspection and enforcement authorities under RCRA Subtitle I and other applicable statutory and regulatory provisions.
The Environmental Protection Agency (EPA) is proposing an approval of revisions to the Maricopa County Air Quality Department (MCAQD) portion of the Arizona State Implementation Plan (SIP). These revisions concern emissions of particulate matter from incinerators, burn-off ovens, and crematories. We are proposing to approve revisions to a local rule that regulates these emissions sources under the Clean Air Act (CAA or "Act"). We are taking comments on this proposal and plan to follow with a final action.
The Environmental Protection Agency (EPA) is issuing a Notice of Intent to delete one site, Corozal Well, from the National Priorities List (NPL) and requests public comments on this proposed action. The NPL, promulgated pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The EPA and the Commonwealth of Puerto Rico, through the Puerto Rico Department of Natural and Environmental Resources (PRDNER), have determined that all appropriate response actions under CERCLA have been completed. However, this deletion does not preclude future actions under Superfund.
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Maricopa County Air Quality Department (MCAQD or "County") portion of the Arizona State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOC) from architectural coatings. Architectural coatings include house paints, stains, industrial maintenance coatings, traffic coatings, and other similar products. We are proposing to approve local rules to regulate these emission sources under the Clean Air Act (CAA or "Act"). The revisions would update the Arizona SIP by replacing an outdated rule version with the current version in effect and would lower VOC emissions limits for some architectural coatings if contingency measures are triggered in the future. We are taking comments on this proposal and plan to follow with a final action.
Pursuant to the Solid Waste Disposal Act of 1965, as amended (commonly known as the Resource Conservation and Recovery Act (RCRA)), the Environmental Protection Agency (EPA) is proposing to approve revisions to the State of Maryland's Underground Storage Tank (UST) program submitted by Maryland (Maryland or State). This action is based on EPA's determination that these revisions satisfy all the requirements needed for program approval. This action also proposes to codify EPA's approval of Maryland's state program and to incorporate by reference (IBR) those provisions of Maryland's regulations and statutes that EPA has determined meet the requirements for approval. The provisions will be subject to EPA's inspection and enforcement authorities under sections 9005 and 9006 of RCRA Subtitle I and other applicable statutory and regulatory provisions. In the "Rules and Regulations" section of this issue of the Federal Register, EPA is approving this action by a direct final rule. If no significant negative comment is received, EPA will not take further action on this proposed rulemaking, and the direct final rule will be effective 60 days from the date of publication in this Federal Register. If you want to comment on EPA's proposed approval of Maryland's revisions to its state UST program, you must do so at this time.
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Wyoming State Implementation Plan (SIP) submitted by the Wyoming Department of Environmental Quality (WDEQ) on December 16, 2024. WDEQ requested EPA approve the revisions for Chapters 2, 3, 4, 8, and 14 in the Wyoming Air Quality Standards and Regulations (WAQSR) The revised rules include non-substantive updates to rule language that ensure consistent grammar, formatting, and written clarity as well as updated references to the Code of Federal Regulations. These revisions do not change the intent or scope of each rule. The EPA is proposing approval of these SIP revisions because we have determined that they are in accordance with the requirements for SIP provisions under the Clean Air Act (CAA or the Act). The proposed approval of WAQSR Chapter 2, section 4 of the December 16, 2024 submittal supersedes the revisions to this section contained in WDEQ's February 10, 2014 SIP submittal that the EPA had not previously acted on. In the "Rules and Regulations" section of this Federal Register, we are approving these SIP revisions as a direct final rule without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule.

Montana's 2022 SIP submission addresses the requirement that states revise their long-term strategies every implementation period to make reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas. Montana's 2022 SIP submission also addresses other applicable requirements for the second implementation period of the regional haze program.
