It must also identify actions to be taken during operation to mitigate adverse environmental impacts, particularly erosion and must clearly explain how the site will be rehabilitated after extractive activities end. (b) Setbacks for processing machinery. Processing machinery must be located consistent with setback standards for structures from ordinary high water levels of public waters. (5) Mining of metallic minerals and peat. Mining of metallic minerals and peat, as defined in M.S. §§ 93.44 to 93.51, as they may be amended from time to time, shall be a permitted use provided the provisions of M.S. §§ 93.44 to 93.51, as they may be amended from time to time, are satisfied.
