Learn More🌫️Louisiana's Air Quality Regulation Proposal by EPA on SO₂ Transport
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve the portion of the State Implementation Plan (SIP) submittal from the State of Louisiana demonstrating that the State satisfies the interstate transport requirements of section 110(a)(2)(D)(i)(I), also known as the "good neighbor" provision of the CAA, for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) primary National Ambient Air Quality Standard (NAAQS). The good neighbor provision requires each State's implementation plan contain adequate provisions prohibiting the interstate transport of air pollution in amounts that will contribute significantly to nonattainment, or interfere with maintenance, of a NAAQS in any other State.

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving revisions to the Texas State Implementation Plan (SIP) submitted to the EPA by the Texas Commission on Environmental Quality (TCEQ or State) on December 18, 2023. The SIP revisions address Control of Air Pollution from Motor Vehicles and establish a Motor Vehicle Inspection and Maintenance (I/M) program for the San Antonio ozone nonattainment area. The revisions also update definitions and address options for displaying a vehicle's registration as proof of compliance with I/M requirements. Additionally, this final action terminates the EPA's requirement to promulgate a Federal Implementation Plan (FIP) for a Basic I/M program in the San Antonio nonattainment area.

This regulation establishes an exemption from the requirement of a tolerance for residues of choline chloride (CASRN 67-48-1) when used as an inert ingredient (adjuvant) applied to or on animals. Stratacor, Inc. on behalf of Emery Olochemicals LLC, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of choline chloride, when used in accordance with the terms of the exemption.
Learn More🌫️EPA Finalizes Air Quality Standards for Washington Area
The Environmental Protection Agency (EPA) is finalizing multiple actions related to the Washington, DC-MD-VA nonattainment area (the Washington Area or the Area) for the 2015 8-hour ozone national ambient air quality standards (2015 ozone NAAQS). First, the EPA is determining that the Washington Area attained the 2015 ozone NAAQS by the applicable attainment date of August 3, 2024. Second, the EPA is determining that the Washington Area has clean data under the EPA's Clean Data Policy. Lastly, the EPA is taking final action on an exceptional events request submitted by the District of Columbia (DC) on March 20, 2024, and concurred on by the EPA on July 17, 2024. This action addresses the EPA's obligation under Clean Air Act (CAA) sections 179(c) and 181(b)(2) to determine whether the Washington Area attained the 2015 ozone NAAQS by the August 3, 2024 attainment date and, as set forth in the EPA's Clean Data Policy, will suspend the obligation of DC, the State of Maryland (MD), and the Commonwealth of Virginia (VA) to submit certain attainment planning requirements for as long as the Washington Area continues to attain the 2015 ozone NAAQS. This action is being taken under the CAA.

Learn More🌱Revised Pesticide Registration Procedures and Business Implications
The Environmental Protection Agency (EPA or Agency) is announcing the availability of Pesticide Registration Notice (PR Notice) 2025-1, entitled "Revised Procedures for Citing Data to Support Pesticide Registrations (EPA Forms No. 8570-34 and 8570-35)." PR Notices are issued by the Office of Pesticide Programs (OPP) to inform pesticide registrants and other interested persons about important policies, procedures, and registration related decisions, and serve to provide guidance to pesticide registrants and OPP personnel. This PR Notice supersedes PR Notice 98-5, entitled "New forms for the Certification with Respect to Citation of Data" dated June 12, 1998. The revised procedures eliminate the requirement to submit two paper versions of the completed data matrix form and establishes electronic online submissions. EPA anticipates that these changes will reduce burden for the registrants and the Agency.
