📜EPA Extends Comment Period on 6PPD Regulatory Investigation

In the Federal Register of November 19, 2024, EPA issued an advance notice of proposed rulemaking soliciting public comment on and any additional information relevant to the potential risks associated with N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) (CASRN 793-24-8, DTXSID 9025114) and its transformation product, 6PPD-quinone (CASRN 2754428-18-5, DTXSID 301034849). EPA is soliciting that information, along with information about potential alternatives and regulatory options, to help inform the Agency's consideration of potential future regulatory actions under the Toxic Substances Control Act (TSCA). With this document, EPA is extending the comment period by 60 days, from January 21, 2025, to March 24, 2025.

🌍EPA Revises Federal Implementation Plan for Sulfur Dioxide in Montana

The Environmental Protection Agency (EPA) is revising a Federal Implementation Plan (FIP) applicable to sulfur dioxide (SO<INF>2</INF>) emissions from four sources located in Billings and Laurel, Montana. Specifically, the EPA is revising a portion of the FIP promulgated by the EPA in 2008 (2008 Billings/Laurel SO<INF>2</INF> FIP) by removing a provision which contained an affirmative defense for exceedances of flare emission limits during malfunctions, startups, and shutdowns. The EPA is taking this action pursuant to the Clean Air Act (CAA).

🌍Updated EPA Regulations on Aerosol Coatings and VOCs Compliance

The U.S. Environmental Protection Agency (EPA) is finalizing amendments to the National Volatile Organic Compound Emission Standards for Aerosol Coatings. This action revises national emission standards for the aerosol coatings (aerosol spray paints) category under the Clean Air Act (CAA), which requires control of volatile organic compound (VOC) emissions from certain categories of consumer and commercial products for purposes of reducing VOC emissions contributing to ozone formation and ozone nonattainment. The regulation employs a relative reactivity-based approach to control aerosol coating products' contribution to ozone formation by encouraging the use of less reactive VOC ingredients in formulations. In this final rule, the EPA is updating coating category product-weighted reactivity (PWR) limits, adding new compounds and reactivity factors, updating existing reactivity factors, revising the rule's default reactivity factor, amending thresholds for VOC regulated by the rule, amending reporting requirements, updating test methods to reflect more recent versions, adding a new compliance date, and making clarifying edits.

🌍EPA Updates Ozone Measurement Calibration Requirements for 2025

The Environmental Protection Agency (EPA) is correcting a final rule published in the Federal Register on October 12, 2023, that became effective on November 13, 2023. The final rule updated the current ozone absorption cross-section to the recommended consensus- based value of 1.1329x10<SUP>-17</SUP> cm\2\ molecule<SUP>-1</SUP> or 304.39 atm<SUP>-1</SUP> cm<SUP>-1</SUP>. After publication, the EPA became aware of an error in the preamble text regarding the date for State, local, and Tribal monitoring agencies to complete implementation of the new ozone cross-section value, as well as a lack of clarity as to which entities the 2025 and 2026 implementation dates apply. With this action, the EPA is updating the final rule preamble and regulatory text to clarify the applicable implementation dates and the specific entities to which they apply. These corrections do not include any substantive changes to the final rule.

🏭EPA Approves Permit for Viejas Pit Stop Gas Station in California

This notice announces that the U.S. Environmental Protection Agency (EPA), Region 9, issued an approval to the Viejas Band of Kumeyaay Indians under the Clean Air Act's Tribal Minor New Source Review (NSR) Program. The EPA approved the Viejas Band of Kumeyaay Indians' Request for Coverage under the General Air Quality Permit for New or Modified Minor Source Gasoline Dispensing Facilities in Indian Country within California for the Viejas Pit Stop. This approval authorizes the construction of the Viejas Pit Stop under the Tribal Minor NSR Program.

🌍Montana EPA Approves Change to Oxygenated Fuels Program

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Montana Department of Environmental Quality (MDEQ or "the State"), on January 30, 2024, requesting to change the status of gasoline requirements (the "oxygenated fuels" or "oxyfuels" program) in the Missoula, Montana Carbon Monoxide (CO) Limited Maintenance Plan (LMP) from active control measure to a contingency measure. The SIP revision contains a non- interference demonstration under the Clean Air Act (CAA), which concludes that converting the oxygenated gasoline program from a control measure to a contingency measure in the Missoula CO LMP would not interfere with attainment or maintenance of the CO National Ambient Air Quality Standard (NAAQS). The EPA is finalizing approval of Montana's SIP submittal pursuant the CAA.

♻️EPA Reopens Comment Period for Waste Combustor Regulation Updates

The Environmental Protection Agency (EPA) is reopening the comment period on the proposed Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Large Municipal Waste Combustors Voluntary Remand Response and 5-Year Review. The original proposed rule was published on January 23, 2024, with a 60-day comment period closing March 25, 2024. With this notification, EPA is reopening the public comment period for an additional 6 months, from January 16, 2025, to July 16, 2025.

♻️Updated EPA Regulations on Coal Combustion Residuals Management

The Environmental Protection Agency (EPA or the Agency) is taking direct final action to correct errors and clarify several provisions published in the Federal Register on May 8, 2024. This May 8, 2024 rule (Legacy Final Rule) established regulatory requirements for legacy coal combustion residuals (CCR) surface impoundments and CCR management units, among other things, under the Resource Conservation and Recovery Act (RCRA).
