Questions

NEPA environmental assessment: what people ask

Do I need an EA or an EIS?

An agency prepares an EIS when a proposed action has a reasonably foreseeable significant effect on the human environment, and an EA when it does not or the significance is unknown. If one of the agency's categorical exclusions fits, neither is needed.

How long can an EA take?

One year. NEPA gives a lead agency one year to finish an EA and two years for an EIS, counted from the earliest of its decision that the document is needed, notice that a right-of-way application is complete, or, for an EIS, its notice of intent.

Can the applicant write the EA?

Yes. NEPA requires lead agencies to let a project sponsor prepare an EA or EIS under the agency's supervision. The agency must independently evaluate the document and takes responsibility for its contents.

Do the CEQ regulations still apply?

No. CEQ removed its NEPA regulations effective April 11, 2025. Agencies now work from the statute and their own procedures, such as USDA's at 7 CFR part 1b. Ask which procedures your agency adopted before you pick a format.
