7 CFR 1794.62 - Supplemental EIS.
(a) A supplement to a draft or final EIS shall be prepared, circulated, and given notice by RUS and the applicant in the same manner (exclusive of scoping) as a draft and final EIS (see § 1794.61).
(b) Normally RUS and the applicant will have published notices of intent to prepare a supplement to a final EIS in those cases where a ROD has already been issued.
(c) RUS, at its discretion, may issue an information supplement to a final EIS where RUS determines that the purposes of NEPA are furthered by doing so even though such supplement is not required by 40 CFR 1502.9(c)(1). RUS and the applicant shall concurrently have a notice of availability published. The notice requirements shall be the same as for a final EIS and the information supplement shall be circulated in the same manner as a final EIS. RUS shall take no final action on any proposed modification discussed in the information supplement until 30 days after the RUS notice of availability or the applicant's notice is published, whichever occurs later.
