Title 42 › Chapter CHAPTER 55— - NATIONAL ENVIRONMENTAL POLICY › Subchapter SUBCHAPTER IV— - FEDERAL PERMITTING IMPROVEMENT › § 4370m–6
Claims asking a court to review a federal agency’s approval for a covered project must be filed within 2 years after the agency’s final action is published in the Federal Register, unless another law sets a shorter deadline. For actions tied to an environmental review under NEPA, the person suing must have submitted a comment during that review, and their comment must have been detailed enough to tell the lead agency what the issue was, or the agency must have denied a fair chance to comment. Agencies must consider new information that meets NEPA rules after a comment period closes. If a supplemental environmental document is required, that document counts as a separate final action and starts a new 2-year filing period. Nothing here creates a new right to sue or stops claims that someone broke the terms of an approval. When a court considers a temporary restraining order or preliminary injunction against an agency or project sponsor, it must weigh harms to public health, safety, the environment, and possible major job losses, and it must not assume those harms can be fixed. Except for the 2-year rule above, this law does not change what final agency actions can be reviewed, does not override other statutes, does not make approval more likely, and does not stop public comment or the authorities of federal, state, local agencies, tribes, metropolitan planning organizations, or project sponsors.
