(a) The National Environmental Policy Act of 1969 (NEPA), 42 U.S.C. 4321 et seq., establishes national policies and goals for the protection of the environment. Section 102(2) of NEPA contains certain procedural requirements directed toward the attainment of such goals. In particular, all federal agencies are required to give appropriate consideration to the environmental effects of their proposed actions in their decisionmaking and to prepare detailed environmental statements on proposals for legislation significantly affecting the quality of the human environment and on other major federal actions significantly affecting the quality of the human environment.

(b) Executive Order No. 11991 of May 24, 1977, directed the Council on Environmental Quality (CEQ) to issue regulations to implement the procedural provisions of NEPA. Accordingly, CEQ issued final NEPA regulations, 40 CFR parts 1500-1508, (“The NEPA regulations”). These regulations provide that each federal agency shall, as necessary, adopt implementing procedures to supplement the regulations. The NEPA regulations identify those sections of the regulations which must be addressed in agency procedures.
