BLM rules and regulations for Wilderness Areas are codified under…
§ 6305.30 What are the steps BLM must take in issuing an access authorization to valid occupancies?
(a) Before issuing an access authorization to mining claims or other valid occupancies wholly surrounded by wilderness, BLM will make certain that:
(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.
(b) After issuing an access authorization, BLM will make certain that you situate and build the route that BLM approves to minimize adverse impacts on the natural resource values of the wilderness area.
