The Department finalized and published its NEPA procedures in the Code of Federal Regulations (43 CFR Part 46) on October 15, 2008. Previously, the Department’s NEPA procedures were included in Part 516, Chapters 1 – 6 of the DM. Portions of Chapters 1 - 6 that were not converted into the regulations are revised and updated in Chapters 1 – 3 of Part 516 as information and explanatory guidance. Chapter 7 was not included in the final rule because it provides internal administrative guidance specific to Departmental review of environmental documents prepared by other Federal agencies. Chapter 7 is revised and renumbered as Chapter 4.
