The U.S. Environmental Protection Agency (EPA) is correcting a final rule that published in the Federal Register (FR) on 24 February 2026, and will become effective on 27 April 2026. The EPA finalized 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 7 May 2024 ("MATS NESHAP"). This action corrects inadvertent typographical errors and minor omitted text in the Federal Register. The corrections described in this action do not affect the substantive requirements of the final rule that repeal specific amendments to the MATS NESHAP, promulgated on 7 May 2024. The correction is effective 27 April 2026. POC is Christopher Werner, tele: (919) 541-5133; and email: werner.christopher@epa.gov. (Federal Register 16 April 2026 [Rule] Pages 20368-20369)

Texas has become the "Energy Capital of the World" and is leading the way in production of both traditional and renewable sources of energy. A state larger than any European country with landscapes ranging from major metropolitan to rural, or deserts to forests to coastal areas, Texas has a wide range of environmental challenges affecting its diverse communities. The state is known for its oil and gas reserves and abundant industry, but it's also home to newer, cleaner sources of energy such as solar farms, wind farms, and hydrogen production plants. All that energy must go somewhere – be it transmitted on Texas's own electrical grid, stored in batteries made at one of the state's battery factories, transmitted via pipeline, or shipped out by road, rail, or water – and Texas does it all. A&WMA ACE is recognized as a premier international conference, featuring content from international environmental experts from industry, researchers, consulting, legal, and government. The conference will feature over 200 platform and poster presentations, nearly 40 panels, and multiple concurrent tracks each day on air, waste, clean energy, sustainability, and environmental management topics.

The workshop presentations provide a comprehensive overview of vapor intrusion (VI), covering fundamental concepts, risk assessment, and practical response strategies. They emphasize the importance of conceptual site models, appropriate statistical interpretation of environmental data, and current best practices for evaluating soil gas and groundwater contributions to indoor air risk. Emerging issues such as updated health concerns and the potential for vapor-forming PFAS are highlighted alongside advances in modeling and simulation tools used to assess VI pathways. The sessions also address mitigation and remediation approaches, including cost-effective construction techniques and vapor flux reduction methods, while underscoring the importance of community perspectives, communication, and trust in implementing effective VI responses.

In the aftermath of Hurricane Florence and Helene, the design community and elected officials asked a critical question: Can these systems--and the communities they serve--be made more resilient? While extreme events cannot be fully prevented, there are important design, siting, construction, and maintenance choices that improve performance over time. This will cover both big-picture considerations and practical strategies for siting, design, construction, and maintenance to improve long-term performance. The session combines a short virtual presentation with an interactive discussion, giving participants the opportunity to compare approaches, share challenges, and identify practical strategies for managing system performance in real-world conditions

Under the Clean Air Act (CAA), the U.S. Environmental Protection Agency (EPA) is required to determine the applicable volume requirements for the Renewable Fuel Standard (RFS) for years after those specified in the statute. The EPA is establishing the applicable volumes and percentage standards for 2026 and 2027 for cellulosic biofuel, biomass-based diesel (BBD), advanced biofuel, and total renewable fuel. The EPA is also partially waiving the 2025 cellulosic biofuel volume requirement and revising the associated percentage standard due to a shortfall in cellulosic biofuel production. Finally, the EPA is promulgating several regulatory changes to the RFS program, including removing renewable electricity as a qualifying renewable fuel under the RFS program (eRINs) and making minor revisions to the biogas provisions of the RFS program. This rule is effective on 15 June 2026, except for amendatory instruction 47, which is effective on 28 April 2026, and amendatory instruction 17, which is effective on 1 January 2027.

The EPA is proposing to improve protection of public health and recover valuable energy and mineral resources by designating scrap tires, including previously abandoned scrap tires, that are combusted in cement kilns, as non-waste fuel. In addition, the EPA is proposing to revise the definition of established tire collection program to include abandoned scrap tires that are recovered for use as fuel so they can be managed the same as collected scrap tires. These proposed regulatory changes support several goals of the Resource Conservation and Recovery Act (RCRA) by facilitating the use of abandoned scrap tires as a non-waste fuel and ingredient in Portland cement manufacturing while simultaneously reducing risks to human health and addressing environmental harms caused by tire piles. These proposed revisions are amendments to the Non-Hazardous Secondary Materials (NHSM) regulations, which establish standards and procedures for identifying whether non-hazardous secondary materials are solid wastes when legitimately used as fuels or ingredients in combustion units.
