🌍EPA Approves VOC Emission Limits for Knowlton Technologies
The Environmental Protection Agency (EPA) is approving a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a Source-specific SIP (SSSIP) revision for Knowlton Technologies LLC, located at 213 Factory Street, Watertown, New York (the Facility). The control options in this SSSIP revision address volatile organic compound (VOC) Reasonably Available Control Technology (RACT) for the Facility source identified as two 10,000-gallon underground storage tanks holding virgin methanol. This action is being taken in accordance with the requirements of the Clean Air Act (CAA) for implementation of the 2008 and 2015 ozone NAAQS. The EPA proposed to approve this rule on November 26, 2024, and received no comments. This final action will not interfere with ozone NAAQS requirements and meets all applicable requirements of the CAA.

The Environmental Protection Agency (EPA) is proposing to determine that the Sacramento Metro, California area attained the 2008 8-hour ozone national ambient air quality standards (NAAQS) by its December 31, 2024 attainment date. This proposed determination is based on quality-assured and certified ambient air quality monitoring data from 2022 through 2024. If we finalize this determination as proposed, the requirement for the State to have contingency measures for reasonable further progress (RFP) and attainment for the 2008 ozone NAAQS will no longer apply for this area. We are taking comments on this proposal and plan to follow with a final action. Elsewhere in this Federal Register, we are making an interim final determination that will stay and defer the imposition of Clean Air Act (CAA or "Act") sanctions associated with a disapproval action related to the contingency measures requirement for this area.

The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. As published, the service information referenced in certain paragraphs of the regulatory text is incorrect, and the dates specified in the "System Airworthiness Limitation No. 3--Fan Blade Out Conditions" text and "System Airworthiness Limitation No. 4--Engine Nacelle Maintenance Errors" text of figure 1 to paragraph (j) of the regulatory text are incorrect. This document corrects those errors. In all other respects, the original document remains the same.
Learn More✈️Proposed Airworthiness Directive for Airbus A350
The FAA proposes to supersede Airworthiness Directive (AD) 2023-02-18, which applies to certain Airbus SAS Model A350-941 and - 1041 airplanes. AD 2023-02-18 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-02-18, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2023-02-18 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The Environmental Protection Agency (EPA) is making an interim final determination to stay and defer the imposition of sanctions under the Clean Air Act (CAA), based on a proposed determination that the Sacramento Metro area has attained the 2008 8-hour ozone national ambient air quality standards (NAAQS) by its December 31, 2024, attainment date. The proposed determination of attainment is published elsewhere in this issue of the Federal Register.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS332C helicopters. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness (ICAs) and the existing approved maintenance or inspection program, as applicable, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 and 440), CL-600-2C10 (Regional Jet Series 700, 701, and 702), CL-600- 2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by the determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G C-Band). This AD requires installing a new radio frequency (RF) bandpass filter on the coaxial line between the radio altimeter and the receive antenna in the aft equipment compartment. The FAA is issuing this AD to address the unsafe condition on these products.
