Lesson Learned: Groom, gravel with crushed rock, and compact haul roads. When the aforementioned cannot be performed, safe distances must be maintained between personnel and moving vehicles and equipment. Inspect haul roads to assure that the road surface has not degraded and large rocks have not worked themselves to the surface or fallen from a vehicle on to the road surface.
Recognize changing conditions and evaluate the impact on operations. In one instance, the area of the waste site floor decreased with the increased depth of the excavation, thus reducing the distance between moving vehicles and equipment. In the second instance, a well drilling crew moved in near an unmaintained section of the haul road and the distance from the crew to the haul road was not evaluated.
