The SPEED Act reforms the National Environmental Policy Act (NEPA) to streamline federal environmental reviews for projects. It limits agencies to considering only "proximate" environmental effects directly tied to a specific project (not speculative or distant impacts), sets strict 180-day deadlines for court remands, and restricts judicial review to procedural errors - not environmental outcomes. This primarily affects federal agencies (like the EPA or Corps of Engineers) and project developers (e.g., for infrastructure, energy, or construction projects) by reducing review scope and accelerating approvals. The bill clarifies NEPA is purely procedural, prohibiting courts from substituting their judgment on environmental effects or delaying actions for new scientific data after deadlines.
