 Subpart 1216.3_Procedures for Implementing the National Environmental 
                            Policy Act (NEPA)
 
Sec.  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'' (Sec.  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.
