Environmental Science Associates hosted a webinar examining rapid changes in federal environmental permitting, covering topics such as streamlined categorical exclusions under NEPA, cultural resources consultation under Section 106, and the growing use of AI tools in environmental review workflows. Experts noted that agencies face increasing pressure to accelerate infrastructure permitting timelines while maintaining legally defensible documentation, particularly as recent court decisions and regulatory rescissions create greater agency discretion and less standardized guidance. Organizations are advised to invest in adaptable workflows and early interagency coordination to manage permitting risk in this shifting landscape.

This document outlines principles and steps for conducting cumulative effects analysis in environmental impact assessments. It covers identifying cumulative effects issues, establishing geographic and temporal boundaries, and determining which effects are important from a cumulative perspective. https://ceq.doe.gov/docs/ceq-publications/ccenepa/sec2.pdf

This document introduces the concept of cumulative environmental effects analysis under NEPA, explaining how multiple minor actions can combine to create significant environmental impacts. It defines cumulative effects as impacts resulting from incremental effects of actions combined with past, present, and future actions, and discusses the purpose and implementation of cumulative effects analysis by federal

This is a legal filing in the U.S. Court of Appeals for the D.C. Circuit in which the U.S. Environmental Protection Agency asks the court to vacate its own previously issued air quality standard, arguing that EPA lacked the statutory authority to revise the standard without completing a full review process. The case centers on National Ambient Air Quality Standards (NAAQS) under the Clean Air Act, not airport noise policy. This document does not contain information relevant to Sea-Tac Airport noise policy.

In September 2025, the Council on Environmental Quality (CEQ) issued updated non-binding guidance to federal agencies on how to conduct environmental reviews under the National Environmental Policy Act (NEPA), replacing earlier guidance from February 2025. The update streamlines the permitting process by incorporating a recent Supreme Court ruling limiting the scope of required environmental analysis, removing climate change and environmental justice considerations, and introducing an optional fee-based program that cuts review timelines in half. Agencies are encouraged to revise their own NEPA procedures using a provided template while continuing existing review processes without delay.
