This section was derived from section 469n(f) of Title 16, Conservation, which was amended by Pub. L. 113–291, div. B, title XXX, § 3033(e), Dec. 19, 2014, 128 Stat. 3777. For applicability of that amendment to this section, see section 6(b) of Pub. L. 113–287, set out as a Transitional and Savings Provisions note preceding section 100101 of this title. Former section 469n(f) of Title 16 was amended by Pub. L. 113–291 by inserting “, except that the amount authorized to be appropriated to carry out this section not appropriated as of the date of enactment of the First State National Historical Park Act shall be reduced by $6,500,000” before period at end.

The date of enactment of the First State National Historical Park Act, referred to in Amendment Not Shown in Text note above, probably means the date of enactment of section 3033 of Pub. L. 113–291, which provided for the establishment of the First State National Historical Park and was approved Dec. 19, 2014. See section 410rrr of Title 16, Conservation. No act with the title First State National Historical Park Act has been enacted.
