Section 771.127 - Record of decision(a) When the final EIS is not combined with the ROD, the Administration will complete and sign a ROD no sooner than 30 days after publication of the final EIS notice in the FEDERAL REGISTER or 90 days after publication of a notice for the draft EIS, whichever is later. The ROD will present the basis for the decision as specified in 40 CFR 1505.2 , summarize any mitigation measures that will be incorporated in the project, and document any required Section 4(f) approval in accordance with part 774 of this chapter. To minimize hardcopy requests and printing costs, the Administration encourages the use of project websites or other publicly accessible electronic means to make the ROD available.(b) If the Administration subsequently wishes to approve an alternative that was not identified as the preferred alternative but was fully evaluated in the draft EIS, combined FEIS/ROD, or final EIS, or proposes to make substantial changes to the mitigation measures or findings discussed in the ROD, a revised or amended ROD must be subject to review by those Administration offices that reviewed the final EIS under § 771.124(a) or § 771.125(c) . To the extent practicable, the approved revised or amended ROD must be provided to all persons, organizations, and agencies that received a copy of the final EIS.
