How NEPA practitioners use AI to draft cumulative-impact analyses that withstand challenge.
AI can synthesize public-records data into a cumulative-impact section but the practitioner verifies every cited source.
The National Environmental Policy Act (NEPA) requires federal agencies to assess the environmental impacts of major federal actions. For significant projects, this means producing an Environmental Impact Statement (EIS). One of the most legally contested sections of any EIS is cumulative impact analysis: the assessment of how the proposed action, combined with other past, present, and reasonably foreseeable future actions, affects shared environmental resources — air quality, water, wildlife habitat, cultural resources. Cumulative impact analysis requires synthesizing a large body of public records: previously approved projects, ongoing permitted activities, proposed projects in the pipeline, and the current baseline condition of the affected resources. This is exactly the kind of document-synthesis task where AI can provide genuine value — inventorying relevant actions, drafting impact tables, and identifying where different projects' effects overlap on the same resources. The critical constraint is that every statement in a cumulative impact section must be traceable to a verifiable, citable source. NEPA practitioners routinely face legal challenges, and an AI-hallucinated citation — a document that does not exist or does not say what the EIS claims — is grounds for remand and potentially for litigation. The appropriate workflow is to require the AI to produce specific document and page citations for every factual claim, then independently verify each one before incorporating it into the draft.
