The EPA is withdrawing its proposed rule entitled "Definition of Hazardous Waste Applicable to Corrective Action for Releases From Solid Waste Management Units." The Agency issued the proposed rule to: amend the regulatory definition of hazardous waste applicable to corrective action to address releases from solid waste management units at hazardous waste treatment, storage, and disposal facilities permitted under the RCRA and make conforming amendments related to the definition amendment; and add the statutory corrective action authorities to the section of the regulations that provides notice that the statutory definitions, rather than the regulatory definitions, apply to certain sections of the statute. The Agency has concluded that the proposed revisions to the existing regulations would have complicated, rather than contributed to, efficient implementation of corrective action. For those reasons EPA has determined that withdrawal is appropriate. The proposed rule published on 8 February 2024 (89 FR 8598) is withdrawn as of 8 May 2026.

A significant component of responding to and recovering from large-scale or isolated events is the management of wastes and materials resulting from the incident itself or from activities cleaning up after the incident. The quantification, segregation, transportation, staging, storage, and disposal of waste can be an arduous and costly undertaking that is difficult to manage, regardless of whether it results from natural, accidental, or intentional disasters. Waste must be holistically considered with decisions being made regarding remediation throughout the response and recovery timeline. To facilitate planning and the proper management of disaster wastes and materials, EPA developed several waste planning and management tools for chemical, biological, radiological, or nuclear incidents and natural disasters. This suite of tools can assist decision makers with waste management decisions in the pre-planning, mitigation, response, and recovery phases of an incident. This webinar will provide an overview of several EPA tools currently available to support decision making and planning for waste management following a large-scale event.

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.
