14 CFR 1216.314 - Tiering.
Actions which are the subject of an environmental impact statement and which represents projects of broad scope may contain within them component actions of narrower scope, perhaps restricted to individual sites of activity or sequential stages of a mission, and which themselves may require environmental assessments and, where necessary, environmental impact statements. The CEQ Regulations provide that agencies may use “Tiering” (§ 1508.28 of the CEQ Regulations) of environmental impact statements to relate such broad and narrow actions. When employing tiering, Headquarters officials shall, by reference, make maximum use of environmental documentation already available, and avoid repetition.
