(a) NASA will complete the final environmental impact statement not later than the date that is two years after the date on which NASA provides notice of intent on a public-facing website that an environmental impact statement will be prepared.
(b) The environmental impact statement will be published (unless the deadline is extended) on the day the deadline elapses, in as substantially complete form as is possible.
(c) If NASA determines it cannot meet the deadline prescribed by NEPA sec. 107(g)(1)(A), 42 U.S.C. 4336a(g)(1)(A), it must consult with the non-Federal project sponsor, if any, pursuant to NEPA sec. 107(g)(2), 42 U.S.C. 4336a(g)(2). After such consultation, if needed, it may establish a new deadline. Cause for establishing a new deadline is only established if the environmental impact statement is so incomplete, at the time at which NASA determines it cannot meet the statutory deadline, that issuance would, in NASA's view, result in an inadequate analysis. Such new deadline must provide only so much additional time as is necessary to complete such environmental impact statement. The announcement of the new deadline will specify the reason why the environmental impact statement was not able to be completed under the statutory deadline and whether the non-Federal project sponsor, if any, consented to the new deadline.
(d) When the environmental impact statement is published, a certification will be incorporated into the environmental impact statement certifying that the resulting environmental impact statement represents NASA's good-faith effort to fulfill NEPA's requirements within the congressional timeline; that such effort is substantially complete; and that, in NASA's expert opinion, it has thoroughly considered the factors mandated by NEPA; and that, in NASA's judgment, the analysis contained therein is adequate to inform and reasonably explain NASA's final decision regarding the proposed Federal action.
