NEPA Implementation
To assist Federal agencies in effectively implementing the environmental policy and "action forcing" provisions of NEPA, CEQ issued Regulations for Implementing the Procedural Provisions of the National Environmental Policy Act (40 CFR §§ 1500–1508). In 1980,CEQ issued the guidance document, Forty Questions and Answers on the CEQ Regulations. Since that time, CEQ has published additional NEPA process guidance and information covering a variety of issues.
To address the NEPA responsibilities established by CEQ, FHWA issued regulations Environmental Impact and Related Procedures (23 CFR §771) and corresponding guidance, Technical Advisory (T 6640.8A): Guidance for Preparing and Processing Environmental and Section 4(f) Documents. The Technical Advisory provides detailed information on the contents and processing of environmental documents.
