(1) Milling operations are presumed completed or ceased and thus are subject to the reclamation time schedule outlined in the approved reclamation plan when the mill has ceased operations for a period of two years or more. A permittee may rebut this assumption by providing evidence satisfactory to the department, consistent with ARM 17.24.150(2) , that the operations have not in fact been abandoned or completed.

(2) Reclamation plans must provide that all discharges from completed operations or operations in a state of temporary cessation will be consistent with provisions of ARM 17.24.151.
