🌍New York Air Plan Approval for Fuel Composition and Use Regulations
The Environmental Protection Agency (EPA) is approving revisions to the New York State Implementation Plan (SIP) concerning the control and reduction of sulfur and particulate matter emissions from facilities in New York State. The SIP revisions consist of amendments to regulations outlined within New York's Codes, Rules and Regulations (NYCRR) for sulfur in fuel limits and the use of waste oil as fuel. The intended effect of the revisions is to approve control strategies, required by the Clean Air Act (CAA), which will result in emission reductions that will help attain and maintain National Ambient Air Quality Standards (NAAQS) for sulfur dioxide and fine particulate matter emissions throughout New York State. Additionally, the revisions will establish applicability criteria, composition limits, and permitting requirements for waste oils; provide monitoring, recordkeeping, and reporting requirements for facilities that are determined eligible to burn waste oil; update conditions required for the firing of waste oils in space heaters at automotive maintenance/service facilities to align with both Federal and New York State hazardous waste regulations; and simplify and streamline implementation of the regulation through the correction of typographical errors and elimination of obsolete regulatory references within provisions. This action is being taken in accordance with the requirements of the CAA.

Learn More🌬️Proposed EPA Rule for Eastern Kern Air Quality
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Eastern Kern Air Pollution Control District (EKAPCD or "District") portion of the California State Implementation Plan (SIP). This revision concerns emissions of oxides of nitrogen (NO<INF>X</INF>) from stationary gas turbines. We are proposing to approve a local rule to regulate these emission sources under the Clean Air Act (CAA or "Act"). We are taking comments on this proposal and plan to follow with a final action.
Learn More🌍Proposed Clean Data Determination for Guam's Piti-Cabras Area
The Environmental Protection Agency (EPA) is proposing a clean data determination (CDD) for the Piti-Cabras, Guam sulfur dioxide (SO<INF>2</INF>) nonattainment area ("Piti-Cabras area") based on our determination that the area has attained the 2010 1-hour SO<INF>2</INF> National Ambient Air Quality Standard (NAAQS, "standard," or "2010 SO<INF>2</INF> NAAQS"). In designated nonattainment areas where air quality data demonstrate that a NAAQS has been attained, the EPA interprets certain requirements of the Clean Air Act (CAA) as no longer applicable for so long as air quality continues to meet the standard. Under this Clean Data Policy, the EPA may issue a determination of attainment, known as a CDD, that a nonattainment area is attaining the relevant NAAQS. If finalized, this proposed CDD would suspend the obligation to submit certain attainment planning requirements for the Piti-Cabras area for as long as the area continues to attain the 2010 SO<INF>2</INF> NAAQS or until the area is formally redesignated.
Learn More🌫️Missouri's St. Louis Area Reclassified as Serious Ozone Nonattainment
The Environmental Protection Agency (EPA) is accepting comment on a determination that the Missouri portion of the St. Louis, MO-IL bi-state nonattainment area failed to attain the 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date. The effect of failing to attain by the applicable attainment date is that the area is reclassified by operation of law to "Serious" nonattainment for the 2015 ozone NAAQS. On November 25, 2024, the EPA published a final action in the Federal Register which determined that the St. Louis area failed to attain the 2015 ozone NAAQS by the Moderate area attainment date. That action also reclassified the area to Serious by operation of law with an effective date of December 31, 2024. On January 24, 2025, the EPA received a petition for reconsideration of that final action from the State of Missouri. On March 5, 2025, EPA Region 7 granted the petition for reconsideration and stated our intention to undergo a notice and comment rulemaking. Therefore, the EPA is accepting comment on the determination that the St. Louis area failed to attain by the attainment date. The Illinois portion of the St. Louis, MO-IL bi-state area is addressed separately.
Learn More💰Proposed Repeal of Emission Standards for Coal and Oil Utilities
In this action, the U.S. Environmental Protection Agency (EPA) is proposing to repeal specific amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating Units (EGUs), commonly referred to as the Mercury and Air Toxics Standards (MATS), that were promulgated on May 7, 2024. The amendments that the EPA is proposing to repeal include the revised filterable particulate matter (fPM) emission standard, which serves as a surrogate for non-mercury hazardous air pollutant (HAP) metals for existing coal-fired EGUs; the revised fPM emission standard compliance demonstration requirements; and the revised mercury (Hg) emission standard for lignite-fired EGUs.
Learn More🏭EPA Finalizes Hazardous Waste Delisting for WRB Refinery
The Environmental Protection Agency (EPA) is granting 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. This determination is based on information the petitioner provided to the Agency, completion of sampling, and risk assessment using the Delisting Risk Assessment Software (DRAS) to determine whether the waste poses a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported or disposed of, or otherwise managed. This final rule responds to a petition submitted by WRB Refinery to exclude stormwater solids from the definition of a hazardous waste. If not delisted, the stormwater solids are listed as F037 (primary oil/water/solids separation sludge). After careful analysis of the petition and evaluation of comments submitted by the public, the EPA has concluded that the petitioned waste is not hazardous waste when disposed of in Subtitle D landfills. This exclusion applies to the stormwater solids generated at WRB Refinery Borger, Texas facility. Accordingly, this final rule excludes the petitioned waste from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when disposed of in a Subtitle D landfill but imposes testing conditions to ensure that the future-generated waste remain qualified for delisting.

Learn More🦙Proposed Endangered Species Listing for Seven Pangolin Species
We, the U.S. Fish and Wildlife Service (Service), propose to list seven species of pangolin distributed throughout Asia and Africa as endangered under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12-month finding on a petition to list these species. After a review of the best available scientific and commercial information, we find that listing these species is warranted. Accordingly, we propose to list the Chinese pangolin (Manis pentadactyla), Indian pangolin (Manis crassicaudata), Sunda pangolin (Manis javanica), Philippine pangolin (Manis culionensis), white-bellied pangolin (Phataginus tricuspis), black- bellied pangolin (Phataginus tetradactyla) and giant pangolin (Smutsia gigantea) as endangered species under the Act. Finalizing this rule as proposed would add these species to the List of Endangered and Threatened Wildlife and extend the Act's protections to these species. We also propose to revise the entry for Temminck's ground pangolin, which is listed as an endangered species under the Act, to reflect the species' current common name spelling and to use the most recently accepted scientific name.
Learn More🌱Proposed RFS Changes for 2026 and 2027
Under the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is required to determine the applicable volume requirements for the Renewable Fuel Standard (RFS) for years after those specified in the statute. EPA is proposing the applicable volumes and percentage standards for 2026 and 2027 for cellulosic biofuel, biomass-based diesel (BBD), advanced biofuel, and total renewable fuel. EPA is also proposing to partially waive the 2025 cellulosic biofuel volume requirement and revise the associated percentage standard due to a shortfall in cellulosic biofuel production. Finally, EPA is proposing several regulatory changes to the RFS program, including reducing the number of Renewable Identification Numbers (RINs) generated for imported renewable fuel and renewable fuel produced from foreign feedstocks and removing renewable electricity as a qualifying renewable fuel under the RFS program (eRINs).
