Agencies Collectively Move to Overhaul Environmental Review Regulations
On July 3, 2025, numerous federal agencies initiated an effort to revise the manner in which they comply with the National Environmental Policy Act (NEPA). NEPA, a cornerstone of environmental governance and project development in the U.S., has historically been implemented through regulations from the Council on Environmental Quality (CEQ). The DC Circuit questioned the legality of those regulations, as well as CEQ’s authority to implement them. And at the direction of President Trump’s February 25, 2025 Executive Order 14154 — “Unleashing American Energy” — CEQ rescinded its NEPA implementing regulations. In place, CEQ provided guidance for agencies that instructed them to update their NEPA procedures by February 2026 in a manner consistent with recent statutory amendments that prioritizes “efficiency and certainty over any other policy objectives.” Today, we are getting our first glimpse into what that process will look like.
EPA Updates Clean Air Act Standards Applicable to Small Waste Incinerators
On June 30, 2025, the U.S. Environmental Protection Agency (EPA) finalized updates to its New Source Performance Standards (NSPS) and Emission Guidelines for Other Solid Waste Incineration (OSWI) units under the Clean Air Act (CAA). These units — combustion systems that incinerate solid waste from commercial or institutional sources not otherwise regulated under specific incinerator categories — include very small municipal waste combustors and institutional incinerators. The final rule includes applicability-related and definitional changes expanding the class of incinerators subject to NSPS, revises the OSWI subcategories and tightens emission limits for key pollutants. It also adopts changes to startup, shutdown, and malfunction (SSM), and expands testing, monitoring, reporting, and recordkeeping requirements that will affect both existing and new OSWI units.
