Updates to Marine Engineering Standards: Notice of proposed rulemaking - The Coast Guard proposes to incorporate by reference updated marine engineering standards and eliminate outdated or unnecessarily prescriptive regulations in Title 46 of the Code of Federal Regulations (CFR) subchapter F. This proposed rule is part of a continuing effort for regulatory reform that increases compliance options for the regulated public while providing a cost savings to the regulated public and the U.S. government.

Regulation of Persistent, Bioaccumulative, and Toxic Chemicals Under TSCA Section 6(h); Phenol, Isopropylated Phosphate (3:1); Further Compliance Date Extension: (...) Specifically, EPA is proposing to extend the compliance date applicable to the processing and distribution in commerce of certain PIP (3:1)-containing articles, and the PIP (3:1) used to make those articles until 31 October 2024, along with the associated recordkeeping requirements for manufacturers, processors, and distributors of PIP (3:1)-containing articles. EPA is also announcing its intention to commence a new rulemaking effort on PIP (3:1) and four other persistent, bioaccumulative, and toxic (PBT) chemicals that have been regulated under TSCA section 6(h) . EPA is anticipating issuing a proposal to this end in 2023.

Commercial Harbor Craft Regulation: Proposed rule - Amends rules to provide for more stringent engine emissions performance standards for NOx and particulate matter. Vessel owners and operators would need to meet performance standards between 2023 and 2032 according to a schedule based on vessel category and engine model year. Proposes to amend section 2299.5, title 13, division 3, chapter 5.1 of the California Code of Regulations (CCR) and section 93118.5, title 17, chapter 1, subchapter 7.5, CCR.

Energy Conservation Program: Test Procedures for Cooking Products: Notice of proposed rulemaking and announcement of public meeting - The U.S. Department of Energy ("DOE") proposes to establish a test procedure for a category of cooking products, i.e., conventional cooking tops, under a proposed new appendix. The proposed test procedure would adopt the latest version of the relevant industry standard with modifications to adapt the test method to gas cooking tops, offer an optional method for burden reduction, normalize the energy use of each test cycle, include measurement of standby mode and off mode energy use, update certain test conditions, and provide certain clarifying language. This NOPR also proposes to retitle the existing cooking products test procedure for microwave ovens only. DOE is seeking comment from interested parties on the proposal.

Response to Vacatur of Certain Provisions of the Mercury Inventory Reporting Rule: Final rule - The Environmental Protection Agency (EPA) is revising regulations associated with persons who must report data to the Agency's mercury inventory established under the Toxic Substances Control Act (TSCA) . Those reporting requirements were set forth in a final rule entitled "Reporting Requirements for TSCA Mercury Inventory: Mercury" (hereafter "mercury inventory reporting rule") . These revisions implement an order issued by the United States Court of Appeals for the Second Circuit (Second Circuit), on 5 June 2020.

Hazardous Materials: Suspension of HMR Amendments Authorizing Transportation of Liquefied Natural Gas by Rail: Notice of proposed rulemaking - PHMSA, in coordination with the Federal Railroad Administration (FRA), proposes to amend the Hazardous Materials Regulations to suspend authorization of liquefied natural gas (LNG) transportation in rail tank cars pursuant to a final rule published in July 2020, pending the earlier of either completion of a separate rulemaking under RIN 2137-AF54 evaluating potential modifications to requirements governing rail tank car transportation of LNG, or 30 June 2024.

Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review: This document comprises three distinct groups of actions under the Clean Air Act (CAA) which are collectively intended to significantly reduce emissions of greenhouse gases (GHGs) and other harmful air pollutants from the Crude Oil and Natural Gas source category. First, the EPA proposes to revise the new source performance standards (NSPS) for GHGs and volatile organic compounds (VOCs) for the Crude Oil and Natural Gas source category under the CAA to reflect the Agency's most recent review of the feasibility and cost of reducing emissions from these sources. Second, the EPA proposes emissions guidelines (EG) under the CAA, for states to follow in developing, submitting, and implementing state plans to establish performance standards to limit GHGs from existing sources (designated facilities) in the Crude Oil and Natural Gas source category. Third, the EPA is taking several related actions stemming from the joint resolution of Congress, adopted on 30 June 2021 under the Congressional Review Act (CRA), disapproving the EPA's final rule titled, "Oil and Natural Gas Sector: Emission Standards for New, Reconstructed, and Modified Sources Review," 14 September 2020 ("2020 Policy Rule") . This proposal responds to the President's 20 January 2021, Executive order (E.O.) titled "Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis," which directed the EPA to consider taking the actions proposed here.

Significant New Use Rules on Certain Chemical Substances (21-2.F): PA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMNs) . The chemical substances received "not likely to present an unreasonable risk" determinations pursuant to TSCA. The SNURs require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the use, under the conditions of use for that chemical substance, within the applicable review period. (...)

Significant New Use Rules on Certain Chemical Substances (21-2.5e): EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMNs) and are also subject to Orders issued by EPA pursuant to TSCA. The SNURs require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the use, under the conditions of use for that chemical substance, within the applicable review period. (...)

Protection of Stratospheric Ozone: Listing of HFO-1234yf Under the Significant New Alternatives Policy Program for Motor Vehicle Air Conditioning in Nonroad Vehicles and Servicing Fittings for Small Refrigerant Cans: Pursuant to the EPA's Significant New Alternatives Policy program, this action proposes to list the refrigerant 2,3,3,3-tetrafluoroprop-1-ene, also known as HFO-1234yf or R-1234yf, as acceptable, subject to use conditions, in the motor vehicle air conditioning end-use for certain types of newly manufactured nonroad (also called off-road) vehicles, which includes some vehicles that are also considered heavy-duty vehicles. (...) In addition, EPA is proposing to require unique servicing fittings for use with small refrigerant cans (two pounds or less) of 2,3,3,3-tetrafluoroprop-1-ene that are used to service onroad and nonroad vehicles. Finally, EPA is proposing to add a reference to the Agency's regulations under the Toxic Substances Control Act for 2,3,3,3-tetrafluoroprop-1-ene for the proposed listings in nonroad vehicles and previous listings for certain onroad vehicles.
