The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 2000EX airplanes. This proposed AD was prompted by a report of simultaneous failures of the main DC buses powered by Generator 1 (GEN1), and Generator 2 (GEN2) after flap extension during approach. This proposed AD would require revising the existing airplane flight manual (AFM). The FAA is proposing this AD to address the unsafe condition on these products.

The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to incorporate by reference a regulatory guide that approves unconditioned code cases published by the American Society of Mechanical Engineers (ASME). This action would allow nuclear power plant applicants and licensees to use the code cases as voluntary alternatives to engineering standards for nuclear power plant components. These standards are set forth in the ASME Boiler and Pressure Vessel Code and ASME Operation and Maintenance of Nuclear Power Plants, which are currently incorporated by reference into the NRC's regulations. The NRC is requesting comments on this proposed rule.
Learn More✈️Proposed Airworthiness Directive for Airbus Canada Aircraft
The FAA is revising a notice of proposed rulemaking (NPRM) that would have applied to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This action revises the NPRM by adding a requirement to re-identify the ceiling panel liners. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, the FAA is requesting comments on this SNPRM.

The Environmental Protection Agency (EPA) has determined that the San Joaquin Valley, California area failed to attain the 1997 8- hour ozone national ambient air quality standard (NAAQS) by its June 15, 2024 "Extreme" area attainment date. This determination is based on quality-assured and certified ambient air quality monitoring data from 2021 through 2023. As a result of this determination, the State of California is required to implement nonattainment contingency measures and the stationary source fee program required under Clean Air Act (CAA) section 185.

The Environmental Protection Agency (EPA) is taking final action to approve the "2023 Maintenance Plan and Redesignation Request for the Revoked 1-Hour Ozone Standard" ("San Joaquin Valley Maintenance Plan" or "Plan") as a revision to the state implementation plan (SIP) for the State of California. The San Joaquin Valley Maintenance Plan includes, among other elements, an emissions inventory consistent with attainment and contingency provisions. The EPA is also finalizing its finding that the State of California's request to redesignate the San Joaquin Valley area from nonattainment to attainment for the revoked 1979 1-hour national ambient air quality standard (NAAQS or "standard") for ozone ("1979 ozone NAAQS," "1-hour ozone NAAQS," or "1-hour ozone standard") meets all the Clean Air Act (CAA or "the Act") criteria for redesignation. Therefore, the EPA is terminating all anti-backsliding obligations for the San Joaquin Valley area for the revoked 1-hour ozone NAAQS.
