43 CFR §3715.2-3

BLM may allow temporary occupancy at a single site to extend beyond the 14-day period described in § 3715.1 if you need to secure the site beyond 14 days through the use of a watchman as allowed by § 3715.2-2, and you have begun consultation with BLM under § 3715.3. If BLM decides not to concur in the occupancy, the temporary occupancy must stop.
