📜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).

This is a proposed extension of the ICR, which is currently approved through February 28. 2025.

🌍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 Proposes New Air Quality Regulations for Arizona Agriculture

The Environmental Protection Agency (EPA) is proposing an approval and a limited approval and limited disapproval of a State Implementation Plan (SIP) submission made by the State of Arizona to address emissions of particulate matter 10 micrometers in diameter or smaller (PM<INF>10</INF>) from agricultural operations. The SIP submission includes an amended statute, two definition rules, and two rules regulating crop and animal operations in Pinal County, Arizona. We are proposing action on local rules 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.

🌍Environmental Impact Statements

🌍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 UCMR 5 Compliance Requirements and Implications for Businesses
