#### "SEC. 102. LANDS WITHIN BOUNDARIES.

"(a) The Secretary is authorized to acquire lands and interests therein within the boundaries of the Park by donation, exchange (in accordance with this section), or purchase with donated or appropriated funds, except that—

"(1) any lands or interests therein owned by the State of Maine or any political subdivision thereof may be acquired only by donation or exchange; and

The Secretary shall provide written notice to the owner of the property of any determination proposed to be made under subsection (a)(2) and shall provide the owner a reasonable opportunity to comment on such proposal.

"(2) For purposes of this section, except as provided in paragraph (3), development or proposed development of private property within the boundaries of the Park that is significantly different from, or a significant expansion of, development existing as of November 1, 1985, shall be considered by the Secretary as detrimental to the values for which the Park was established.
