(b) The written notice under paragraph (a) of this section will include the following:

(5) Time frames for taking the corrective actions;

(6) Potential consequences and penalties for failure to take corrective action; and

(7) A statement that unauthorized livestock or other property may not be removed or disposed of unless authorized by BIA under paragraph (b)(4) of this section.
