(a) A consistency determination is required for ongoing Federal agency activities other than development projects initiated prior to management program approval, which are governed by statutory authority under which the Federal agency retains discretion to reassess and modify the activity. In these cases the consistency determination must be made by the Federal agency at the earliest practicable time following management program approval, and the State agency must be provided with a consistency determination no later than 120 days after management program approval for ongoing activities which the State agency lists or identifies through monitoring as subject to consistency with the management program.

(b) A consistency determination is required for major, phased federal development project decisions described in § 930.36(d) which are made following management program approval and are related to development projects initiated prior to program approval. In making these new decisions, Federal agencies shall consider effects on any coastal use or resource not fully evaluated at the outset of the project. This provision shall not apply to phased federal decisions which were specifically described, considered and approved prior to management program approval (e.g., in a final environmental impact statement issued pursuant to NEPA).
