Carbon Tetrachloride (CTC); Regulation Under the Toxic Substances Control Act (TSCA)
The Environmental Protection Agency (EPA) is proposing to address the unreasonable risk of injury to human health presented by carbon tetrachloride (CTC) under its conditions of use as documented in EPA's 2020 Risk Evaluation for Carbon Tetrachloride and 2022 Revised Unreasonable Risk Determination for Carbon Tetrachloride pursuant to the Toxic Substances Control Act (TSCA). CTC is a volatile, organic compound that is primarily used as a feedstock (i.e., processed as a reactant) in the making of products such as refrigerants, aerosol propellants, and foam-blowing agents. TSCA requires that EPA address by rule any unreasonable risk of injury to health or the environment identified in a TSCA risk evaluation and apply requirements to the extent necessary so that the chemical no longer presents unreasonable risk. EPA determined that CTC presents an unreasonable risk of injury to health due to cancer from chronic inhalation and dermal exposures and liver toxicity from chronic inhalation, chronic dermal, and acute dermal exposures in the workplace. To address the identified unreasonable risk, EPA is proposing under TSCA to establish workplace safety requirements for most conditions of use, including the condition of use related to the making of low Global Warming Potential (GWP) hydrofluoroolefins (HFOs), prohibit the manufacture (including import), processing, distribution in commerce, and industrial/commercial use of CTC for conditions of use where information indicates use of CTC has already been phased out, and establish recordkeeping and downstream notification requirements. The use of CTC in low GWP HFOs is particularly important in the Agency's efforts to support the American Innovation and Manufacturing Act of 2020 (AIM Act) and the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer, which was ratified on October 26, 2022.
Agency Information Collection Activities; Proposed Collection; Comment Request; Identification, Listing and Rulemaking Petitions (Renewal), EPA ICR No. 1189.32, OMB Control No. 2050-0053
The Environmental Protection Agency (EPA) is planning to submit the information collection request (ICR), Identification, Listing and Rulemaking Petitions (Renewal), EPA ICR No. 1189.32, OMB Control No. 2050-0053 to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act (PRA). Before doing so, the EPA is soliciting public comments on specific aspects of the proposed information collection as described in SUPPLEMENTARY INFORMATION. This is a proposed extension of the ICR, which is currently approved through March 31, 2024. An Agency may not conduct or sponsor and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number.
Air Plan Approval and Air Quality Designation; KY; Redesignation of the Northern Kentucky Portion of the Cincinnati, OH-KY 2015 8-Hour Ozone Nonattainment Area to Attainment
On September 21, 2022, the Commonwealth of Kentucky, through the Kentucky Energy and Environment Cabinet (Cabinet), Division of Air Quality (DAQ), submitted a request for the Environmental Protection Agency (EPA) to redesignate the Northern Kentucky portion (hereinafter referred to as the ``Northern Kentucky Area'' or ``Area'') of the Cincinnati, Ohio- Kentucky, 2015 8-hour ozone nonattainment area (hereinafter referred to as the ``Cincinnati OH-KY Area'') to attainment for the 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards) and to approve a State Implementation Plan (SIP) revision containing a maintenance plan for the Area. The Cabinet submitted this request and SIP revision through a letter dated September 20, 2022, and supplemented it on November 22, 2022. EPA is proposing to approve the Commonwealth's plan for maintaining attainment of the 2015 8-hour ozone standard in the Northern Kentucky Area, including the motor vehicle emission budgets (MVEBs) for nitrogen oxides (NOX) and volatile organic compounds (VOCs) for the years of 2026 and 2035 for the Area, to incorporate the maintenance plan into the SIP, and to redesignate the Area to attainment for the 2015 8-hour ozone NAAQS. EPA previously approved the redesignation request and maintenance plan for the Ohio portion of the Cincinnati, OH-KY Area. EPA is also notifying the public of the status of EPA's adequacy determination for the MVEBs for the Area.

Notice of Receipt of Requests to Voluntarily Cancel Certain Pesticide Registrations and Amend Registrations To Terminate Certain Uses
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 pesticide products and to amend their pesticide 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 registrations have been cancelled or uses terminated only if such sale, distribution, or use is consistent with the terms as described in the final order.
