The bigger boundary is subject to valid existing rights
What the document says“shall be subject to valid existing rights, including land within a designated utility transmission corridor or a transmission line right-of-way grant approved by the Secretary in a record of decision issued before the date of the enactment of this Act”
Section 3(c)(1) of the Act. The expansion of the Conservation Area boundary made by subsection (a) is subject to valid existing rights, including land within a designated utility transmission corridor or a transmission line right-of-way grant the Secretary approved in a record of decision issued before the date of enactment.
What the document actually says“shall be subject to valid existing rights, including land within a designated utility transmission corridor or a transmission line right-of-way grant approved by the Secretary in a record of decision issued before the date of the enactment of this Act”
Rights people already hold still count. That takes in land set aside for power lines.
Making the protected land bigger does not undo deals made before. A record of decision is the paper that says a deal was approved.
No action is recorded against this proposal. That is not evidence that none has been taken, and nobody has yet read it against the record. See what the tracker does not yet cover.
