Montana Regulatory Program

Document 2026-02981 is a Final Rule published by the Department of Interior in the Federal Register on February 13, 2026, with an effective date of March 16, 2026. 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. View the original at https://www.federalregister.gov/documents/2026/02/13/2026-02981/montana-regulatory-program.
