Some people need a quick prompt to remind them. Others respond to evidence that it makes a difference or that it's a normal thing everyone does. Nudging people to consistently recycle or adopt waste reduction practices isn't easy but it is possible. Key to unlocking zero waste behavior is a thoughtful messaging strategy grounded in the distinct values, social context and other factors that guide a person's actions. This webinar will feature two sustainability behavior experts discussing messaging strategies rooted in science, from extensive CBSM-style campaigns to simple signage prompts. Their presentations will cite best practices and real-world case studies of public engagement initiatives that have resulted in meaningful improvements.

U.S. EPA is updating and improving the RCRAInfo public website. RCRAInfo's Hazardous Waste Information Platform will replace RCRAInfo Web on 19 September 2025.

The Hazardous Waste Information Platform will provide streamlined, comprehensive access to hazardous waste data in a variety of formats. If you have questions, please join our next e-Manifest User Call on 2 September 2025, at 2:00 pm ET.

USFWS proposes to list the Borneo earless monitor (Lanthanotus borneensis), a lizard species from Borneo, as a threatened species under the ESA. This determination also serves as their 12-month finding on a petition to list the Borneo earless monitor. After a review of the best scientific and commercial data available, they find that listing the species is warranted. Accordingly, they propose to list the Borneo earless monitor as a threatened species with protective regulations under section 4(d) of the Act ("4(d) rule"). If finalize this rule as proposed would add this species to the List of Endangered and Threatened Wildlife and extend the Act's protections to the species. Comments must be received by 14 October 2025. Rachel London, Manager, Branch of Delisting and Foreign Species, Ecological Services Program, USFWS; email rachel_london@fws.gov; tele 703-358-2171.

The discussion will cover the initiative's purpose, origins, and biggest impacts on daily acquisition work, with a focus on how the Strategic Acquisition Guidance (SAG) framework will streamline policy, strengthen professional judgment, and unify guidance and practice across the federal acquisition landscape. Panelists will also address culture change, implementation support, and opportunities for the workforce to contribute feedback during the transformation.

The TSCA Inventory is a list of all existing chemical substances manufactured, processed or imported in the U.S. under TSCA that do not otherwise qualify for an exemption or exclusion. This biannual update to the TSCA Inventory includes EPA's regular posting of non-confidential TSCA Inventory data. The next regular update of the TSCA Inventory is planned for winter 2026. EPA is also updating the TSCA Master Inventory File, which includes the full, specific chemical identities claimed as confidential. The TSCA Master Inventory File now contains 86,862 chemicals of which 42,578 are active (currently known to be in use) in U.S. commerce. Other updates to the TSCA Inventory include updates to commercial activity data, unique identifier data and to regulatory flags (e.g., Significant New Use Rules and test orders).

EPA published preliminary Toxics Release Inventory (TRI) data about chemical releases, waste management and pollution prevention activities that took place during 2024 at more than 21,000 industrial and federal facilities across the country. EPA is also making a routine update to its online TRI tools to include new reporting from submissions, revisions and withdrawals from 2023 and earlier that EPA has processed since October 2024. These updated data are, in part, the result of EPA's work to assist industrial facilities in collecting and submitting accurate TRI data. Link to Toxics Release Inventory Data (TRI)

Common financial analysis metrics such as simple payback period and return on investment (ROI) do not fully capture the costs and benefits of projects. This webinar will present a holistic financial assessment framework and highlight partner experiences in leveraging various financial metrics to build a strong case for energy efficiency initiatives.

USFWS propose to remove Virginia sneezeweed (Helenium virginicum) from the Federal List of Endangered and Threatened Plants. Their review indicates that the threats to Virginia sneezeweed have been eliminated or reduced to the point that the species no longer meets the definition of an endangered or threatened species under the ESA. Accordingly, they propose to delist Virginia sneezeweed. If finalized the prohibitions and conservation measures provided by the Act, particularly through sections 7 and 9, would no longer apply to Virginia sneezeweed. They will accept comments received or postmarked on or before 6 October 2025.

The EPA is proposing to repeal all greenhouse gas (GHG) emission standards for light-duty, medium-duty, and heavy-duty vehicles and engines to effectuate the best reading of Clean Air Act (CAA) section 202(a). EPA propose that CAA section 202(a) does not authorize the EPA to prescribe emission standards to address global climate change concerns and, on that basis, propose to rescind the Administrator's prior findings in 2009 that GHG emissions from new motor vehicles and engines contribute to air pollution which may endanger public health or welfare. They further propose, in the alternative, to rescind the Administrator's prior findings in 2009 because the EPA unreasonably analyzed the scientific record and because developments cast significant doubt on the reliability of the findings. Lastly, they propose to repeal all GHG emission standards on the alternative bases that no requisite technology for vehicle and engine emission control can address the global climate change concerns identified in the findings without risking greater harms to public health and welfare. Comments must be received on or before 15 September 2025. POC is Alan Stout, Assessment and Standards Division, Office of Transportation and Air Quality, Environmental Protection Agency, 2000 Traverwood Drive, Ann Arbor, MI 48105; tele: (734) 214-4805; email: stout.alan@epa.gov.

Although similar, process control requirements for lagoons and small wastewater treatment plants can differ significantly in key areas. For system managers considering modifications to an existing lagoon or an upgrade to a mechanical plant, understanding the specific needs of each system is essential to maintaining compliance with NPDES permits. This presentation will provide an in-depth comparison of process control requirements and best management practices (BMPs), from preliminary treatment through to final discharge, for both lagoons and small mechanical treatment plants.

The U.S. Fish and Wildlife Service (Service) is removing the Roanoke logperch (Percina rex), a freshwater fish in the perch family (Percidae), 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 Roanoke logperch have been eliminated or reduced to the point that the species no longer meets the definition of an endangered or threatened species under the Endangered Species Act of 1973, as amended (Act). Accordingly, the prohibitions and conservation measures provided by the Act, particularly through sections 7 and 9, will no longer apply to the Roanoke logperch.
