Mojave National Preserve Boundary Adjustment Act

This bill expands the boundary of the Mojave National Preserve to include approximately 20,920 acres of land designated as the Castle Mountains National Monument.

The Department of the Interior must generally administer this land as part of the preserve and in accordance with applicable laws and regulations. With respect to a specified mining area within the national monument, the Bureau of Land Management (BLM) must continue to manage the area until Interior determines that certain conditions related to the cessation of mining activities are met. At that time, Interior must transfer administrative jurisdiction over the land to the National Park Service (NPS).

Interior must ensure the availability of water resources, including groundwater resources, needed for the land added to the preserve.

Finally, the bill transfers administrative jurisdiction over a specified portion of land from the NPS to the BLM.
