(b) If the permittee fails to remove improvements within the time allowed in the permit, the permittee may forfeit the right to remove the improvements and the improvements may become the property of the Indian landowner or at the request of the Indian landowner, we will apply the bond for the removal of the improvement and restoration of the land.
