Environmental Protection Agency August 29, 2022 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is approving the State Implementation Plan (SIP) revision submitted by the State of New Mexico, through the New Mexico Environment Department (NMED), for the purpose of addressing the Clean Air Act (CAA or ``Act'') ``good neighbor'' interstate transport (prongs 1 and 2) infrastructure SIP requirements for the 2010 1-hour Nitrogen Dioxide (NO2) National Ambient Air Quality Standard (NAAQS). Specifically, the EPA is approving New Mexico's June 25, 2021, SIP revision that address prongs 1 and 2 to ensure that air emissions in the State do not significantly contribute to nonattainment or interfere with the maintenance of the 2010 1-hour NO2 NAAQS in any other state. The EPA is approving this action pursuant to section 110 and part D of the CAA and the EPA's regulations.

The Environmental Protection Agency (EPA) is announcing the availability of and requesting public comment on a draft revision to the risk determination for the carbon tetrachloride risk evaluation issued under the Toxic Substances Control Act (TSCA). The draft revision to the carbon tetrachloride risk determination reflects the announced policy changes to ensure the public is protected from unreasonable risks from chemicals in a way that is supported by science and the law. In this draft revision to the risk determination EPA finds that carbon tetrachloride, as a whole chemical substance, presents an unreasonable risk of injury to health when evaluated under its conditions of use. In addition, this draft revised risk determination does not reflect an assumption that all workers always appropriately wear personal protective equipment (PPE). EPA understands that there could be occupational safety protections in place at workplace locations; however, not assuming use of PPE reflects EPA's recognition that unreasonable risk may exist for subpopulations of workers that may be highly exposed because they are not covered by the standards set by the Occupational Safety and Health Administration (OSHA), or their employers are out of compliance with OSHA standards, or because many of OSHA's chemical-specific permissible exposure limits largely adopted in the 1970's are described by OSHA as being ``outdated and inadequate for ensuring protection of worker health.'' This revision, when final, would supersede the condition of use-specific no unreasonable risk determinations in the 2020 Carbon Tetrachloride Risk Evaluation (and withdraw the associated order) and would make a revised determination of unreasonable risk for carbon tetrachloride as a whole chemical substance.

In accordance with the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is issuing a notice of receipt of requests by the registrants to voluntarily cancel their registrations of certain product registrations and to amend certain product registrations to terminate one or more uses. EPA intends to grant these requests at the close of the comment period for this announcement unless the Agency receives substantive comments within the comment period that would merit its further review of the requests, or unless the registrants withdraw their requests. If these requests are granted, any sale, distribution, or use of products listed in this notice will be permitted after the registration has been cancelled or use terminated, only if such sale, distribution, or use is consistent with the terms as described in the final order.
