Approval and Promulgation of Implementation Plans; Wisconsin

로컬 자동 번역 · 원본 출처 언어

요약

USEPA is proposing to disapprove the State of Wisconsin's Prevention of Significant Deterioration (PSD) Rules, Natural Resources (NR) 405.01 through 405.17, as a revision to the Wisconsin State Implementation Plan (SIP). The State developed the rules as Wisconsin's plan to prevent significant deterioration of air quality in areas designated as unclassifiable or attainment of the National Ambient Air Quality Standards (NAAQS) and to satisfy the requirements of part C of the Clean Air Act (Act). USEPA proposes to disapprove these rules because they do not meet USEPA's regulation governing State PSD programs (40 CFR 51.166). Until USEPA approves a SIP submission from Wisconsin satisfying these requirements, the Federal PSD requirements at 40 CFR 52.21 remain applicable within the State of Wisconsin.

Significant New Use Rules on Certain Chemical Substances (25-1.5e)

EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for certain chemical substances that were the subject of premanufacture notices (PMNs) and are also subject to an Order issued by EPA pursuant to TSCA. The SNURs require persons to notify EPA at least 90 days before commencing the manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use in the SNUR. The required notification initiates EPA's evaluation of the conditions of that use for that chemical substance. In addition, the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification; made an appropriate determination regarding that notification; and taken such actions as required by that determination.

Phasedown of Hydrofluorocarbons: Excluding Road and Intermodal Container Transport Refrigeration Units From the Hydrofluorocarbon Leak Repair Requirements

The U.S. Environmental Protection Agency (EPA) is proposing an exemption for road and intermodal container transport refrigeration units (TRUs) from the leak repair requirements established under the American Innovation and Manufacturing (AIM) Act. In the final rule "Phasedown of Hydrofluorocarbons: Management of Certain Hydrofluorocarbons and Substitutes Under the American Innovation and Manufacturing Act of 2020," the EPA established, among other provisions, leak repair requirements for refrigerant-containing appliances with a charge size of 15 pounds or more that contain a hydrofluorocarbon (HFC) or certain substitutes for HFCs. The EPA intended to exempt refrigerant-containing road and intermodal container TRUs from the leak repair requirements and is issuing this proposal to clarify the applicability of these requirements. The EPA is not proposing other amendments or taking comment on any other aspects of the 2024 "Phasedown of Hydrofluorocarbons: Management of Certain Hydrofluorocarbons and Substitutes Under the American Innovation and Manufacturing Act of 2020."
