                    The Niobrara Scenic River Designation Act is subject to the Wild and Scenic Rivers Act of October 2, 1968, (Pub. L. 90-542, 82 Stat. 906), as amended, 16 U.S.C. 1271-1287. Section 3(b) of that Act, 16 U.S.C. 1274(b), provides that “Notice of availability of the boundaries and classification, and of subject boundary amendments shall be published in the                     **Federal Register**                     and shall not become effective until ninety days after they have been forwarded to the President of the Senate and the Speaker of the House of Representatives.” Minor technical boundary changes to System units are authorized by 54 U.S.C. 100506(c).                

                    This boundary amendment will remove a portion of Tract 00001 containing 12.45 acres of unimproved, non-Federal land, more or less, from the Niobrara National Scenic River pursuant to the Judgment of the U.S. District Court in                     *Simmons*                     v.                     *Jarvis,*                     8:13CV98, Doc #120 (D.
