(a) An EA is a concise public document used by the Agency to determine whether to issue a FONSI or prepare an EIS, as specified in subpart D of this part. If, at any point during the preparation of an EA, it is determined that the proposal will have a potentially significant impact on the quality of the human environment, an EIS will be prepared.

(b) Unless otherwise determined by the Agency, EAs will be prepared for all “Federal actions” as described in § 1970.8, unless such actions are categorically excluded, as determined under subpart B of this part, or require an EIS, as provided under subpart D of this part;

(c) Preparation of an EA will begin as soon as the Agency has determined the proper classification of the applicant's proposal. Applicants should consult as early as possible with the Agency to determine the environmental review requirements of their proposals. The EA must be prepared concurrently with the early planning and design phase of the proposal. The EA will not be considered complete until it is in compliance with this part.

(d) Failure to achieve compliance with this part will postpone further consideration of the applicant's proposal until such compliance is achieved or the applicant withdraws the application. If compliance is not achieved, the Agency will deny the request for financial assistance.
