Section 1318.407 - EIS adoption(a) TVA may adopt another agency's EIS, or a portion thereof, provided that the NEPA compliance staff determines that the EIS or portion thereof meets the standards for an adequate EIS.(b) If the NEPA compliance staff determines that the actions covered by the other agency's EIS and TVA's proposed action are substantially the same, TVA may adopt the other agency's EIS as TVA's FEIS (§ 1318.404 ). In making this determination, the NEPA compliance staff, in consultation with other interested TVA entities, will consider whether the scope and analyses in the other agency's EIS adequately address the TVA action. TVA will also review to ensure the scientific accuracy of the analysis and conclusions drawn. TVA must make this determination and the adopted EIS available on its public website.(c) If the NEPA compliance staff determines that the actions covered by the other agency's EIS and TVA's proposed action are not substantially the same, TVA will supplement the other agency's EIS and treat it as TVA's DEIS, including circulating it for comment (§ 1318.403 ).(d) If TVA cooperated in the preparation of an EIS that TVA determines adequately addresses its proposed action, TVA may make a decision about its proposed action no sooner than 30 days after notice of availability of the FEIS was published in the FEDERAL REGISTER. A record of that decision should be prepared consistent with § 1318.405 .(e) If TVA did not cooperate in the preparation of an EIS that TVA determines adequately addresses its proposed action and that it proposes to adopt, NEPA compliance staff will transmit notice of its adoption to EPA for publication of a notice of availability and circulate the FEIS for public comment as to its assessment of impacts as they relate to TVA's proposed action. TVA may make a decision about its proposed action no sooner than 30 days after notice of availability of the FEIS is published in the FEDERAL REGISTER.
