   1. (1)Individually-owned Indian lands; and
   2. (2)Tribes that have not established a rate under paragraph (a) of this section.
3. (c)Indian landowners may give us written authority to grant grazing privileges on their individually-owned Indian land at a grazing rental rate that is:
   1. (1)Above the grazing rental rate set by us; or
   2. (2)Below the grazing rental rate set by us, subject to our approval, when the permittee is a member of the Indian landowner's immediate family as defined in this part.
