A permit ID sign was posted near the entrance gate to the site, though the sign still contains he name of the former permittee.

Mining is actively ongoing in the north block, with topsoil stripping preceding the excavation. To oil is bermed along the west side of the pit. The pit is not dewatered as it is mined. It is growing toward the south. The it is about 10 feet deep or more, and is becoming a pond, as allowed under the original approved plan for this site. The op rotor should ensure that the water rights to expose groundwater still exist, and for what maximum size pond, by contacti g the Colorado Division of Water Resources office in Montrose. The operator should also ensure that slope gradients bel w water line meet any gradient specified in the approved plan. This will act to lessen the reclamation liability. Except for the west side, the pond margins are not encroaching on the permit boundaries. Woo ed thickets exist to the north, east and south of the present pond. The north pond bank is 3:1 or gentler. The east bank st II requires some grading for final reclamation. The bank reclamation on the west side of the pond would involve pushing th bermed material down to attain reclamation gradients there. Other reclamation tasks around the pond, based on the pre ent permitted acreage, amount of disturbance and approved reclamation plan involve topsoil replacement and revegetati n. There are no fuel tanks, processing equipment or mining-related structures onsite. All pitrun is haul d from the site.
