Opening
Opening means the restoration of a specified area of public lands to operation of the public land laws, including the mining laws, and, if appropriate, the mineral leasing laws, the material disposal laws and the Geothermal Steam Act, subject to valid existing rights and the terms and provisions of existing withdrawals, reservations, classifications, and management decisions. Depending on the language in the opening order, an opening may restore the lands to the operation of all or some of the public land laws.
