A bill to establish effluent limitations guidelines and standards and water quality criteria for perfluoroalkyl and polyfluoroalkyl substances under the Federal Water Pollution Control Act. (Congressional Record 11 December 2025 [Senate] Pages S8669-S8671)

Making meaningful progress toward zero waste in corporate and other institutional settings requires a holistic understanding of how waste is generated and managed. Where traditional waste audits analyze discarded waste for insights, zero waste audits look at the steps that products and packaging (materials) follow leading up to that point. Using a systems approach, they evaluate procurement policies and how items are used, as well as end-of-life collection practices and infrastructure, looking for opportunities at each stage to use and manage materials more efficiently. This program will feature a primer describing the elements of a zero waste audit and how to conduct them, followed by a case study showing how Colgate-Palmolive has applied them in a corporate setting. The program will also include an introduction to the TRUE zero waste certification system, a zero waste program.

PHMSA is adopting several amendments to the Hazardous Materials Regulations to reduce unnecessary regulatory burdens associated with the safe transportation of hazardous materials, including energy products. These amendments will reduce costs for hazardous materials transporters and eliminate unnecessary regulatory burdens on fuel transportation while maintaining or increasing the level of safety provided in the Hazardous Materials Regulations. This rule is effective 13 February 2026. POC is Alexander Wolcott, Standards and Rulemaking Division, 202-366-8553, Pipeline and Hazardous Materials Safety Administration, U.S. Department of Transportation, 1200 New Jersey Avenue SE, Washington, DC 20590-0001.

EPA is finalizing amendments to the new source performance standards (NSPS) for stationary combustion turbines and stationary gas turbines pursuant to a review required by the Clean Air Act (CAA). As a result of this review, the EPA is establishing subcategories for new, modified, or reconstructed stationary combustion turbines based on size, rates of utilization, design efficiency, and fuel type. The EPA determined that combustion controls are the best system of emission reduction (BSER) for nitrogen oxide (NOX) emissions for most new, modified, or reconstructed stationary combustion turbines. For one subcategory, the BSER for NOX is combustion controls with the addition of selective catalytic reduction (SCR). The EPA further determined that the BSER for sulfur dioxide (SO2) emissions has not changed since the last NSPS review. Based on these determinations, the Agency is promulgating standards of performance in a new subpart of the Code of Federal Regulations (CFR). The Agency is also adding a subcategory for stationary combustion turbines that are used in temporary applications, exempting certain sources from title V requirements, and finalizing other provisions. The EPA is finalizing amendments to existing regulations to address or clarify specific technical and editorial issues. This final rule is effective on 15 January 2026.

Because the Environmental Protection Agency (EPA) received adverse comment, we are withdrawing the direct final rule Technical Amendments to the Emergency Planning and Community Right-to-Know Act (EPCRA) Hazardous Chemical Inventory Reporting Requirements to Conform to the 2024 OSHA Hazard Communication Standard, published in the Federal Register on 17 November 2025. Effective 9 January 2026, the EPA withdraws the direct final rule published at 90 FR 51187, on 17 November 2025.

OSHA is correcting several inadvertent errors in its Hazard Communication Standard (HCS). Most errors relate to the HCS final rule published in the Federal Register on 20 May 2024. On 9 October 2024, the agency issued a corrections notification and technical amendment to correct errors in that final rule which the agency believed could lead to confusion during the classification process or errors on labels and Safety Data Sheets (SDSs) if not expeditiously corrected. Following publication of the 9 October 2024 corrections notification and technical amendment, OSHA continued its review of the regulatory text and identified additional minor and typographical errors in the regulatory text and appendices to the HCS. OSHA is issuing this correction document to address these additional minor errors. OSHA is also making one technical amendment to an appendix of the HCS unrelated to the 20 May 2024 final rule. The corrections in this document are effective 8 January 2026. POC is Tiffany DeFoe, Director, Office of Chemical Hazards, Metals, Directorate of Standards and Guidance email defoe.tiffany@dol.gov.

EPA is proposing a National Primary Drinking Water Regulation (NPDWR) for perchlorate and a health-based Maximum Contaminant Level Goal (MCLG) under the Safe Drinking Water Act (SDWA). In this action, the EPA is proposing to set the perchlorate MCLG at 0.02 mg/L (20 µg/L). The EPA is also proposing and taking comment on setting an enforceable Maximum Contaminant Level (MCL) for perchlorate at 0.02 mg/L (20 µg/L), 0.04 mg/L (40 µg/L), or 0.08 mg/L (80 µg/L). The EPA is also proposing requirements for water systems to conduct monitoring for perchlorate in drinking water, take mitigation actions if the level exceeds the MCL, provide information about perchlorate to their consumers through public notification and consumer confidence reports, and report to their respective primacy agency. The Administrator has determined that the benefits of this regulation would not justify the costs; however, the EPA is required to issue an NPDWR and MCLG for perchlorate in response to the D.C. Circuit's decision in NRDC v. Regan. Comments must be received on or before 9 March 2026. POC is Anne Lausier, Standards and Risk Management Division, Office of Ground Water and Drinking Water (4607M), Environmental Protection Agency, 1200 Pennsylvania Ave. NW; tele: (202) 564-0518; email: NPDWRperchlorate@epa.gov.
