⚙️DOE Amendments to Compressor Test Procedures
The U.S. Department of Energy ("DOE") is amending the test procedure for compressors to correct an error and to ensure that pressure ratio is expressed in terms of absolute pressure. DOE is also correcting the formula for isentropic efficiency and specific energy consumption of the packaged compressor by incorporating a K<INF>6</INF> correction factor to correct for differences in pressure ratio when testing at differing elevations. Finally, DOE is amending the definition of "air compressor" to include a minor clarification and revise a typographical error.

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).
Learn More🚗New Compliance Requirements for Hydrogen Vehicle Safety Standards
This final rule establishes two new Federal Motor Vehicle Safety Standards (FMVSS) specifying performance requirements for all motor vehicles that use hydrogen as a fuel source. The final rule is based on Global Technical Regulation (GTR) No. 13, Hydrogen and Fuel Cell Vehicles. FMVSS No. 307, "Fuel system integrity of hydrogen vehicles," specifies requirements for the integrity of the fuel system in hydrogen vehicles during normal vehicle operations and after crashes. FMVSS No. 308, "Compressed hydrogen storage system integrity," specifies requirements for the compressed hydrogen storage system to ensure the safe storage of hydrogen onboard vehicles. These two standards will reduce deaths and injuries from fires due to hydrogen fuel leakages and/or explosion of the hydrogen storage system.
Learn More🌍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.
Learn More⚖️New Compliance Rules for Clothes Washer and Dryer Testing 2024
In this final rule, the U.S. Department of Energy ("DOE") is amending the test procedures for residential and commercial clothes washers and consumer clothes dryers to update the test cloth specifications. DOE is also reorganizing the test procedures for improved readability. DOE is conducting this rulemaking to address specific issues and to make minor corrections to the current test procedures. This rulemaking does not satisfy the statutory requirement that, at least once every 7 years, DOE review the test procedures for clothes washers and consumer clothes dryers.

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.
Learn More🌍New EPA Updates to Alaska Air Quality Regulations Announced
The Environmental Protection Agency (EPA) is updating the materials that are incorporated by reference (IBR) into the Alaska State Implementation Plan (SIP). The regulations affected by this update have been previously submitted by the State of Alaska and approved by the EPA. In this final rule, the EPA is also notifying the public of corrections and clarifying changes in the Code of Federal Regulations tables that identify the materials incorporated by reference into the Alaska SIP. This update affects the materials that are available for public inspection at the National Archives and Records Administration and the EPA Regional Office.
Learn More✈️NPRM for Boeing Airworthiness Directive
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports of multiple supplier notices of escapement (NOEs) indicating that seat track splice fittings were possibly manufactured with an incorrect titanium alloy material. This proposed AD would require an inspection of seat track splice fittings to determine the material and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
Learn More✈️Proposed Amendment of Class E Airspace at Beckley, WV
This action proposes to amend the Class E airspace at Beckley, WV. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the Beckley very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. This action will bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.
