EPA NEPA Implementing Procedures

Current understanding

EPA is proposing to amend its procedures for implementing the National Environmental Policy Act (NEPA) and for assessing environmental effects abroad of EPA actions. The proposed rule aims to create procedural efficiencies, harmonize with other federal agencies, incorporate statutory changes from the Fiscal Responsibility Act of 2023 and the One Big Beautiful Bill Act of 2025, align with Executive Order 14154, and reflect the Supreme Court’s Seven County Infrastructure Coalition decision narrowing NEPA review scope. Practical effects would likely include shorter/narrower environmental reviews for EPA actions and updated categorical exclusions; status is proposed rule.

Evidence log

• 2026-04-17 — RED Tape Act: RED Tape Act (HR6398, introduced) would strip EPA’s Clean Air Act §309 authority to review and comment on other agencies’ NEPA actions and proposed federal regulations, complementing EPA’s own proposed update of its NEPA implementing procedures. (novelty: 2)
• 2026-06-15 — Implementing Regulation for National Environmental Policy Act (NEPA): Environmental Effects of the Department of Veterans Affairs Actions: cross-connection with nepa-implementing-procedures: VA’s final NEPA rule and EPA’s proposed NEPA procedure update are parallel agency responses to the same statutory triggers (FRA 2023, OBBBA 2025) and the CEQ regulatory rescission. (novelty: 2)
• 2026-06-25 — Update of Procedures for Implementing the National Environmental Policy Act and Assessing the Environmental Effects Abroad of EPA Actions: cross-connection with nepa-implementing-procedures: Both are agency-level rewrites of NEPA procedures (EPA and NASA respectively) responding to the same post-CEQ regulatory landscape and Supreme Court guidance. (novelty: 3)
