Approval and Promulgation of Implementation Plans; Designation of Areas for Air Quality Planning Purposes; State of California; PM-10; Determination of Attainment for the Coso Junction Nonattainment Area; Determination Regarding Applicability of Certain Clean Air Act Requirements

ローカル自動翻訳 · 情報源の原言語

概要

EPA is proposing to determine that the Coso Junction nonattainment area (CJNA) in California has attained the 24-hour National Ambient Air Quality Standard (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10). This proposed determination is based upon monitored air quality data for the PM-10 NAAQS during the years 2006- 2008. In addition, data for 2009 contained in EPA's Air Quality System (AQS) shows the CJNA continued to attain the PM-10 NAAQS through 2009, and preliminary data for 2010 available to date show no exceedances of the 24-hour NAAQS have been recorded at the CJNA monitoring site. EPA is also proposing to determine that, because the CJNA has attained the PM-10 NAAQS, the obligation to make submissions to meet certain Clean Air Act (CAA or the Act) requirements is not applicable for as long as the CJNA continues to attain the PM-10 NAAQS.

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."

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.
