The Environmental Protection Agency (EPA) is proposing to delay the compliance date for Facility Response Plan (FRP) requirements as well as to make language modifications to align with the Administration's climate change and environmental justice policies in Executive Order 14148 of January 20, 2025. These requirements are for onshore non-transportation-related facilities that could reasonably be expected to cause substantial harm to the environment from a CWA hazardous substance worst case discharge to navigable waters, adjoining shorelines, or the exclusive economic zone. This delay action is necessary to allow the Agency to consider implementation and compliance assistance tools that regulated parties may be able to take advantage of when complying with the new requirements. EPA notes that it cannot quantify the number, nature, and magnitude of covered discharges that may occur during the proposed rule delay period. Comments must be received on or before 6 April 2026.

Following an emergency event, communities need access to clean water for various daily activities and medical purposes. EPA partnered with WaterStep to develop a modular, mobile water treatment system known as Water on Wheels – Emergency Mobile Water Treatment System (WOW Cart). The WOW Cart is an inexpensive and versatile water treatment system about the size of a shopping cart that has been deployed in response to hurricanes, tornadoes, and other disasters. Multiple deployments and discussions with stakeholders have highlighted the lack of a pre-approval process for short-term emergency drinking water systems among many states. This may limit the ability to use such capabilities and get clean water to affected areas quickly. This webinar will provide an overview of the WOW Cart and the Association of State Drinking Water Administrators will discuss their survey of state programs on pre-approval of short-term emergency drinking water systems. It will discuss Kentucky's Lily Pad program, including guidelines for acceptance and monitoring of systems, pre-deployments, and training water utility staff in the operation of these systems.

The Environmental Protection Agency (EPA or the Agency) is updating the list of chemicals subject to toxic chemical release reporting under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act (PPA). Specifically, this action updates the regulations to identify one perfluoroalkyl substance that must be reported pursuant to the National Defense Authorization Act for Fiscal Year 2020 (FY 2020 NDAA) enacted on December 20, 2019. As this action is being taken to conform the regulations to a Congressional legislative mandate, notice and comment rulemaking is unnecessary. This final rule is effective 30 March 2026.

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)
