As the mine has been in operation since 1902, much of the disturbed area associated with the mine was affected prior to the effective date of the Surface Mining Control and Reclamation Act of 1977 and the Colorado Surface Coal Mining Reclamation Act. Baseline environmental factors were not measured, and no topsoil was salvaged prior to previous disturbance. Disturbances which have been conducted since the effective date of the Act have been permitted and conducted in compliance with the Act and Regulations. These activities include the Hubbard Creek Ventilation Fan No. 2 facility, the methane degas wells, the Sanborn Creek Tract, the Elk Creek Facilities, the West Valley and II West Coal Refuse Facilities, and the new Bear Creek Fansite Facility. All other areas of disturbance at the mine occurred prior to the effective date of the Act. All surfaces will be returned to the approximate original contour (AOC) with two exceptions. 14
