Guidelines of the Council on Environmental Quality for the preparation of environmental impact statements.

Definitions and the seven principles of ecology are listed. NEPA expresses or implies all seven. Section 101 is quoted in illustration. CEQ Guidelines implement Sec. 102(2)(C). The reasons for initial delays in implementation are reviewed; these are now largely resolved. The policy involves action through integrating engineering, economics and ecology. Alternative actions must be considered, and short-term effects weighed against the long-term goals. Twelve modes of approach are advocated.
