Mammoth Cave National Park Boundary Adjustment Act of 2025

119th Congress Introduced May 8, 2025

Summary

What This Bill Does

The Mammoth Cave National Park Boundary Adjustment Act amends the 1942 Mammoth Cave statute. It updates the second paragraph by making the existing $350,000 amount adjust for inflation under the Consumer Price Index published by the Bureau of Labor Statistics. It also authorizes the Interior Secretary to acquire approximately 551.14 acres of land or interests in land shown as the Proposed Addition on the May 2025 Mammoth Cave National Park Proposed Southern Boundary Expansion map for Edmonson and Barren Counties, Kentucky. Once acquired, that land can be included in Mammoth Cave National Park.

Who Benefits and How

Mammoth Cave National Park visitors benefit if added land improves park protection, access, or resource management. National Park Service staff benefit from authority to manage the proposed southern boundary addition as part of the park. Kentucky conservation organizations benefit from a federal acquisition path for the 551.14-acre proposed addition. Landowners in the proposed addition benefit if they choose to sell land or interests in land to Interior.

Who Bears the Burden and How

Interior land acquisition staff must negotiate and process any purchase of the 551.14 acres or related interests. Federal taxpayers bear acquisition and management costs for land added to the national park. Bureau of Labor Statistics CPI data becomes part of the statutory calculation for the older $350,000 amount. Local county officials may need to coordinate with the National Park Service on boundary and land-management changes.

  • Authorizes Interior to acquire approximately 551.14 acres for Mammoth Cave National Park.
