To provide for a limitation on availability of funds for U.S. Department of Interior, National Park Service, Centennial Challenge for fiscal year 2024.

HR 2170 sets a $15 million cap on funding for the National Park Service's Centennial Challenge program during fiscal year 2024. This directly affects projects funded through this specific grant initiative, which typically supports park restoration and preservation efforts. The bill prohibits exceeding this limit on available funds without altering other National Park Service programs or funding mechanisms.
