Code of Federal Regulations Title 43. Public Lands:  Interior § 43.6305.30 What are the steps BLM must take in issuing an access authorization to valid occupancies?

(1) You have demonstrated a lack of any existing access rights or alternate routes of access available by deed or under applicable State or common law and that access by non-federally owned routes is not reasonably obtainable;

(2) Your combination of routes and modes of travel, including non-motorized modes, will cause the least impact on the wilderness but, at the same time, will permit the reasonable use of the non-Federal land, valid mining claim, or other valid occupancy;  and

(3) The location, construction, maintenance, and use of the access route that BLM approves will be as consistent as possible with the management of the wilderness area.
