Lead Wheel Weights; Petition for Rulemaking Under the Toxic Substances Control Act (TSCA); Decision Not To Proceed With a Rulemaking
The Environmental Protection Agency (EPA or Agency) has decided not to proceed with the development of a regulation addressing the manufacture, processing, or distribution in commerce of lead for wheel-balancing weights ("lead wheel weights") under the Toxic Substances Control Act (TSCA). This action relates to a citizen petition filed with the Agency in 2009 ("2009 petition"). The 2009 petition, which EPA granted, asked EPA to initiate a rulemaking proceeding to regulate the manufacturing, processing, or distribution in commerce of lead wheel weights. In 2023, the same parties filed a petition for a writ of mandamus ("mandamus petition") that sought to compel EPA to initiate the rulemaking proceeding requested in the 2009 petition. After reviewing the information submitted in response to an advance notice of proposed rulemaking (ANPRM) issued in April 2024 and EPA's technical analysis thereof, EPA has decided not to proceed with the development of a proposed rule. Addressing potential remaining exposures from lead continues to be a high priority for EPA, as reflected in EPA's announcement that "Lead and Lead Compounds" is on its list of candidate chemical substances currently being considered for future prioritization actions under TSCA.
Notice of Approval for Other Use of Phosphogypsum
The Environmental Protection Agency (the EPA or the Agency) has approved, subject to certain conditions, the request for a "Small- scale Road Pilot Project on Private Land in Florida" submitted by Mosaic Fertilizer, LLC in March 2022, and updated by the "Revised Request for Approval of Use of Phosphogypsum in Small-scale Pilot Project", submitted in August 2023. The Agency's review found that Mosaic's request is complete per the requirements of EPA's National Emissions Standards for Hazardous Air Pollutants under the Clean Air Act, and that the potential radiological risks from conducting the pilot project meet the regulatory requirement that the project is at least as protective of public health as maintaining the phosphogypsum in a stack. On October 9, 2024, the EPA issued a pending approval of the request and solicited public comments on the pending approval. While EPA received comments raising questions about the project, no comments were received which led EPA to change the results of its risk analyses for this proposed pilot project. This approval is only for the proposed pilot project, and EPA has placed conditions on the approval to make sure that the project remains within the scope of the application.

Alternative Methods for Calculating Off-Cycle Credits Under the Light-Duty Vehicle Greenhouse Gas Emissions Program: Application From Mitsubishi Motors Corporation
The Environmental Protection Agency (EPA) is requesting comment on an application from Mitsubishi Motors Corporation ("MMC") for off-cycle carbon dioxide (CO2) credits under EPA's light-duty vehicle greenhouse gas emissions standards. "Off-cycle" emission reductions can be achieved by employing technologies that result in real-world benefits, but where that benefit is not adequately captured on the test procedures used by manufacturers to demonstrate compliance with emission standards. EPA's light-duty vehicle greenhouse gas program acknowledges these benefits by giving automobile manufacturers several options for generating "off-cycle" CO2 credits. Under the regulations, a manufacturer may apply for CO2 credits for off-cycle technologies that result in off-cycle benefits. In these cases, a manufacturer must provide EPA with a proposed methodology for determining the real-world off-cycle benefit. MMC submitted their application describing a methodology for determining off-cycle credits from the technology described in their application. Pursuant to applicable regulations, EPA is making this off-cycle credit calculation methodology available for public comment.

Significant New Use Rules on Certain Chemical Substances (24-3.5e)
EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for certain chemical substances that were the subject of premanufacture notices (PMNs) and are also subject to an Order issued by EPA pursuant to TSCA. The SNURs require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rulemaking to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the conditions of that use for that chemical substance. In addition, the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification, made an appropriate determination regarding that notification, and taken such actions as required by that determination.
Trichloroethylene (TCE); Regulation Under the Toxic Substances Control Act (TSCA)
The Environmental Protection Agency (EPA or Agency) is finalizing a rule to address the unreasonable risk of injury to health presented by trichloroethylene (TCE) under its conditions of use. TSCA requires that EPA address by rule any unreasonable risk of injury to health or the environment identified in a TSCA risk evaluation and apply requirements to the extent necessary so that the chemical no longer presents unreasonable risk. EPA's final rule will, among other things, prevent serious illness associated with uncontrolled exposures to the chemical by preventing consumer access to the chemical, restricting the industrial and commercial use of the chemical while also allowing for a reasonable transition period with interim worker protections in place where an industrial and commercial use of the chemical is being prohibited, and provide time-limited exemptions for critical or essential uses of TCE for which no technically and economically feasible safer alternatives are available.
Redesignation of Portions of Westmoreland and Cambria Counties, Pennsylvania for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standards (NAAQS)
The Environmental Protection Agency (the EPA or the Agency) is finalizing the redesignation of portions of Cambria County and Westmoreland County, Pennsylvania, to "nonattainment" for the 2010 1- hour primary sulfur dioxide (SO2) national ambient air quality standard (NAAQS or standard). Westmoreland County was previously designated "attainment/ unclassifiable," and Cambria County was designated "unclassifiable." The EPA notified the Commonwealth of Pennsylvania of its intended redesignation of portions of Cambria and Westmoreland counties on February 17, 2023, and published a Notice of Availability (NOA) for this action on February 12, 2024. The EPA's redesignation of portions of these counties is based on modeled violations of the 2010 1-hour primary SO2 NAAQS.
Findings of Failure To Attain and Reclassification of Areas in Illinois, Indiana, Michigan, Ohio, and Wisconsin as Serious for the 2015 Ozone National Ambient Air Quality Standards
The Environmental Protection Agency (EPA) is determining that the Allegan County, MI; Berrien County, MI; Chicago, IL-IN-WI; Cleveland, OH; Milwaukee, WI; Muskegon County, MI; Sheboygan County, WI; and Illinois portion of the St. Louis, MO-IL areas failed to attain the 2015 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 areas will be reclassified by operation of law to "Serious" nonattainment for the 2015 ozone NAAQS on January 16, 2025, the effective date of this final rule. This action fulfills EPA's obligation under the Clean Air Act (CAA) to determine whether ozone nonattainment areas attained the NAAQS by the attainment date and to publish a document in the Federal Register identifying each area that is determined as having failed to attain and identifying the reclassification.
Brevibacillus Laterosporus Mpp75Aa1.1 and Bacillus Thuringiensis Vpb4Da2 Proteins; Exemptions From the Requirement of a Tolerance
This regulation establishes exemptions from the requirement of a tolerance for residues of the Brevibacillus laterosporus Mpp75Aa1.1 and Bacillus thuringiensis Vpb4Da2 proteins (hereafter Mpp75Aa1.1 and Vpb4Da2 proteins) in or on the food and feed commodities of corn: corn, field; corn, sweet, and corn, pop when used as plant-incorporated protectants (PIP) in corn. Bayer CropScience LP., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting these exemptions. These regulations eliminate the need to establish maximum permissible levels for residues of Mpp75Aa1.1 and Vpb4Da2 proteins.
Designation of Areas for Air Quality Planning Purposes; Redesignation Request and Associated Maintenance Plan for Whatcom County, WA 2010 SO2 Nonattainment Area
On July 25, 2024, the State of Washington (WA) submitted a request for the Environmental Protection Agency (EPA) to redesignate to attainment a portion of Whatcom County immediately surrounding the now permanently closed aluminum smelter, Intalco Aluminum LLC, which the EPA designated nonattainment for the 2010 1-hour primary sulfur dioxide (SO2) National Ambient Air Quality Standard (NAAQS). Washington also submitted a request for the EPA to approve a State Implementation Plan (SIP) revision containing a maintenance plan for the area. The EPA is taking the following final actions: we have determined that the Whatcom County (partial) SO2 nonattainment area (Whatcom County area or area) is attaining the 2010 1-hour primary SO2 NAAQS; we are approving Washington's plan for maintaining attainment of the 2010 1- hour primary SO2 NAAQS in the area; and we are redesignating the Whatcom County area to attainment for the 2010 1-hour primary SO2 NAAQS.
Approval of Air Quality Implementation Plans; New Jersey; Permits and Certificates for Minor Facilities (and Major Facilities Without an Operating Permit), and Air Emission Control and Permitting Exemptions
The Environmental Protection Agency (EPA) is proposing to approve a revision to New Jersey's State Implementation Plan (SIP), submitted by the New Jersey Department of Environmental Protection (NJDEP), to incorporate regulations concerning permits and certificates for minor source facilities and major source facilities without an operating permit. The intended effect of the NJDEP's revisions to the SIP, is to regulate the construction and modification of stationary sources with adequate requirements to ensure that the National Ambient Air Quality Standards (NAAQS) are satisfied. In addition, the NJDEP's revisions will strengthen the SIP by conforming it with the State regulations that were in effect at the time of the SIP submission. If the EPA finalizes this rulemaking as it is being proposed, the Federal air permitting program for New Jersey will be updated, which will better serve the regulated community and help to protect the quality of air in the State.
