36 CFR § 1010.8 - Actions that normally require an EIS.
(a) General procedure. So long as a proposed action or project is not categorically excluded under § 1010.7, the Trust shall require the preparation of an EA to determine if the proposed action or project requires an EIS. Nevertheless, if it is readily apparent to the NEPA Compliance Coordinator that the proposed action or project will have a significant impact on the environment, an EA is not required, and the Trust will prepare or direct the preparation of an EIS without preparing or completing the preparation of an EA. To assist the NEPA Compliance Coordinator in determining if a proposal or action normally requires the preparation of an EIS, the following criteria and categories of action are provided.
(c) Categories of action. The following categories of action normally require an EIS:
(1) Legislative proposals made by the Trust to the United States Congress, other than those described in § 1010.7(b)(9);
(2) Approval, funding, construction, and/or demolition in preparation for construction of any new building, if that activity has a significant effect on the human environment;
(4) Approval or amendment of a general land use or resource management plan for the entire Presidio Trust Area.
