Designates about 12,295 acres of Bureau of Land Management land in Taos County, New Mexico, as the Cerro de la Olla Wilderness and adjusts the Río Grande del Norte National Monument boundary to match a referenced map. It preserves the ability to maintain certain existing wildlife water structures in the new wilderness if they meet specific conditions and requires the Secretary to enter a cooperative wildlife-management agreement with the State of New Mexico within one year. The measure also makes clerical updates to previously enacted conservation law and amends language related to grazing allotments to reflect the new designation.
