The U.S. Environmental Protection Agency (EPA) is finalizing the repeal of specific amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating Units (EGUs), commonly referred to as the Mercury and Air Toxics Standards (MATS), that were promulgated on May 7, 2024. Specifically, the EPA is repealing the revised filterable particulate matter (fPM) emission standard, which serves as a surrogate for non-mercury hazardous air pollutant (HAP) metals for existing coal-fired EGUs; the revised fPM emission standard compliance demonstration requirements; and the revised mercury (Hg) emission standard for lignite-fired EGUs. The EPA is also making technical, non-substantive clarifications to electronic reporting requirements. The final rule is effective on 27 April 2026.

EPA invites the public to nominate experts in Information Technology (IT) to be considered for a three-year membership appointment to the Hazardous Waste Electronic Manifest System ("e-Manifest") Advisory Board (the "Board"). Pursuant to the Hazardous Waste Electronic Manifest Establishment Act (the "e-Manifest Act" or the "Act"), EPA has established the Board to provide practical and independent advice, consultation, and recommendations to the EPA Administrator on the activities, functions, policies, and regulations associated with the Hazardous Waste Electronic Manifest (e-Manifest) System. In accordance with the e-Manifest Act, the EPA Administrator or designee will serve as Chair of the Board. This document solicits nominations for possible consideration of candidates to potentially fill a vacancy on the Board to serve as an IT expert for a three-year appointment. EPA may also consider nominations received through this solicitation to fill any unanticipated future vacancies on the Board for the following positions including an industry representative member with experience in using or representing users of the manifest system; and a state representative member responsible for processing manifests. Nominations of candidates considered for appointment must be received on or before 9 March 2026. POC is Fred Jenkins, tele: (202) 566-0344; email: jenkins.fred@epa.gov.

The Annual WateReuse Symposium is the premier conference on water recycling -- attracting water professionals and water reuse practitioners globally for knowledge-sharing, networking, and collaboration. The Symposium is the most comprehensive water recycling learning opportunity available, covering policy, technology, operations, and communications for applications that range from irrigation and potable reuse to onsite and industrial systems.

In this action, the EPA is rescinding the Administrator's 2009 findings of contribution and endangerment and repealing all GHG emission standards for light-duty, medium-duty, and heavy-duty vehicles and engines to effectuate the best reading of CAA section 202(a)(1). The EPA determines that CAA section 202(a)(1) does not authorize the Agency to prescribe emission standards in response to global climate change concerns for multiple reasons, including the best reading of the statutory terms "air pollution," "cause," "contribute," and "reasonably be anticipated to endanger." This statutory interpretation is corroborated by application of the major questions doctrine. The EPA further determines that GHG emission standards for new motor vehicles and engines do not impact in any material way the public health and welfare concerns identified in the Administrator's prior findings in 2009. On these multiple and independent bases, the EPA concludes that it lacks statutory authority to regulate GHG emissions in response to global climate change concerns under CAA section 202(a)(1) and is not finalizing the additional bases for repeal set out in the proposed rule. This final action is effective on 20 April 2026. POC is Alan Stout tele: (734) 214-4805; email: stout.alan@epa.gov. (Federal Register 18 February 2026 [Rule] Pages 7686-7796)

USFWS are removing the Southeast U.S. distinct population segment (DPS) of the wood stork (Mycteria americana) from the Federal List of Endangered and Threatened Wildlife. After a review of the best scientific and commercial data available, they find that delisting the species is warranted. Their review indicates that the threats to the Southeast U.S. DPS of the wood stork have been eliminated or reduced to the point that the species no longer meets the definition of an endangered species or threatened species under the ESA. Accordingly, the prohibitions and conservation measures provided by the Act, particularly through sections 4 and 7, will no longer apply to the Southeast U.S. DPS of the wood stork. This rule is effective 12 March 2026.

Community infrastructure, such as thermal energy networks, district geothermal, urban forests, shade structures, and smart surfaces, can have a collectively lower upfront cost and lower community-wide energy consumption and the costs of cooling. For example, strategic deployment of cool roofs in Atlanta, mandated by ordinance, are expected to cool the city by 2.4 degrees F in peak summer, deliver $310 million in direct energy savings, and generate $760 million in net financial benefits. This webinar will explore community-system technologies and strategies for resilient cooling and their benefits for community-wide energy reliability, grid resilience, and extreme heat preparedness. Participants will hear directly from experts on targeted solutions and the policy levers needed to scale up their broad adoption.

This Engineering and Construction Bulletin (ECB) is for information only and all Army military construction (MILCON), sustainment, renovation and modernization (SRM) projects, and Civil Works vertical construction projects. The Buy American Act mandates that construction materials be sourced from the U.S. or designated countries to support domestic manufacturing and jobs. This policy is also a significant sustainability strategy, promoting local resilience, ensuring transparency in production standards, supporting recycling practices, and creating a positive community economic impact. Proper implementation requires considering the act during the design phase and verifying materials through submittal reviews and inspections to ensure compliance with contractual requirements.

The Interstate Technology & Regulatory Council (ITRC) provides a comprehensive online toolkit about vapor intrusion (VI). VI is the migration of hazardous vapors from contaminated soil and groundwater into overlying buildings. The toolkit is for regulators, consultants, and building owners to help in decision-making regarding VI and petroleum vapor intrusion (PVI). PVI is a subset of VI, specifically dealing with petroleum hydrocarbons. The toolkit provides a framework for evaluating and managing the vapor intrusion pathway. It describes various tools for investigation, data evaluation, and mitigation.

This training provides general information on how to implement the VI guidance document. It focuses on a four-step approach, offering a high-level overview of each step and detailing the revisions made between the 2020 draft and the final version.
