Montana Regulatory Program

The Office of Surface Mining Reclamation and Enforcement (OSM) approves an amendment to the Montana regulatory program under the Surface Mining Control and Reclamation Act of 1977 (SMCRA or the Act). Montana proposed an addition to the Montana Code Annotated (MCA), which would revise and add regulations in the Administrative Rules of Montana (ARM) pertaining to ownership and control. These changes were required by an October 2, 2009, letter from OSM to Montana and in response, Senate bill 92, was approved by the 2013 Montana Legislature. Montana also proposed other ARM revisions unrelated to ownership and control.
