September 30, 2021 – Federal Register Recent Federal Regulation Documents

Pursuant to the Resource Conservation and Recovery Act, as amended, the Environmental Protection Agency (EPA) proposes to take direct final action to approve revisions to the State of Nevada's Underground Storage Tank (UST) program since the previous authorization on July 17, 1998. This action is based on the EPA's determination that these revisions satisfy all requirements needed for program approval. In the ``Rules and Regulations'' section of this Federal Register, the EPA is approving the changes by direct final authorization because we believe this action is not controversial and do not expect comments that oppose it.

The FAA proposes to supersede Airworthiness Directive (AD) 2020-18-04, which applies to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-18-04 requires a one-time health check of the slat power control unit (PCU) torque sensing unit (TSU), a detailed inspection of the slat transmission systems, corrective actions if necessary, and track 12 slat gear rotary actuator (SGRA) water drainage and vent plug cleaning. Since the FAA issued AD 2020-18-04, it has been determined that the one-time health check must be repetitive instead to monitor the TSU wear, and that the water drainage and vent plug cleaning is no longer required. This proposed AD would require repetitive health checks of the slat PCU TSU, a detailed visual inspection of the slat transmission systems, and corrective actions if necessary; 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 Environmental Protection Agency (EPA) is announcing the availability of a draft document titled, ``Supplement to the 2019 Integrated Science Assessment for Particulate Matter (External Review Draft)'' (EPA/600/R-21/198). The document was prepared by the Center for Public Health and Environmental Assessment (CPHEA) within EPA's Office of Research and Development (ORD) as part of the reconsideration of the 2020 National Ambient Air Quality Standard (NAAQS) for particulate matter (PM). The Supplement represents a targeted review of peer-reviewed studies published since the literature cutoff date (i.e., ~January 2018) of the 2019 Integrated Science Assessment for Particulate Matter (PM ISA). The Supplement and the 2019 p.m. ISA provide the scientific basis for EPA's decisions, in conjunction with additional technical and policy assessments, for the reconsideration of the current NAAQS and the appropriateness of possible alternative standards. EPA is releasing this draft document to seek review by the Clean Air Scientific Advisory Committee (CASAC) and the public. In addition, the date and location of a public meeting for CASAC review of this document will be specified in a separate Federal Register document. This draft document is not final and it does not represent, and should not be construed to represent, any final Agency policy or views. When revising the document, EPA will consider any public comments submitted during the public comment period specified in this notice.

This document amends the Department of Veterans Affairs (VA) Schedule for Rating Disabilities (VASRD) by revising the portion of the schedule that addresses the genitourinary system. This action ensures that the rating schedule uses current medical terminology and provides detailed and updated criteria for evaluation of genitourinary conditions for disability rating purposes.
