25 C.F.R. § 166.607
Is insurance required for a permit?
When we determine it to be in the best interest of the Indian landowners, we will require a permittee to provide insurance. If insurance is required, it must:
(a) Be provided in an amount sufficient to:
(1) Protect any improvements on the permit premises;
(2) Cover losses such as personal injury or death; and
(3) Protect the interest of the Indian landowner.
(b) Identify the tribe, individual Indian landowners, and United States as insured parties.
