16 U.S. Code § 1a–13 - Proposals for boundary changes
In proposing any boundary change after November 28, 1990, the Secretary shall—
(a) consult with affected agencies of State and local governments  surrounding communities, affected landowners and private national, regional, and local organizations;
(b) apply the criteria developed pursuant to section 1a–12 of this title and accompany this proposal with a statement reflecting the results of the application of such criteria;
(c) include with such proposal an estimate of the cost for acquisition of any parcels proposed for acquisition together with the basis for the estimate and a statement on the relative priority for the acquisition of each parcel within the priorities for acquisition of other lands for such unit and for the National Park System.
 So in original. Probably should be followed by a comma.
