There is a plan in place to deal with noxious weeds, particularly white top, that appear at the Terror Creek Loadout. TCLLC will maintain records of herbicide use on the property for inspection by Division personnel. XIV. Protection of Underground Mining A. There are no current or proposed surface mining operations within or next to the Terror Creek Loadout. XV. Subsidence Control A. This section does not apply to this operation, as Terror Creek is a loadout. No mining has occurred or will occur. XVL Concurrent Surface and Underground Mining A. This section does not apply to the Terror Creek Loadout. XVIL Operations on Alluvial Valley Floors Identification of Alluvial Valley Floors A. TCLLC has identified an alluvial deposit extending approximately one mile to the east (upstream) and three miles to the southwest (downstream) of the permit area along the North Fork of the Gunnison River (Map 2). Lands upstream from the permit area are not a part of the hydrologic system that could be affected by the Terror Creek operation; therefore, no determination will be made by the Division for those lands at this time. The valley bottom complex in the immediate vicinity of the proposed permit area (i.e., sections 15 and 22) consists of the current flood plain of the North Fork of the Gunnison and a sloping colluvial deposit which rises above the flood plain to the north. Cropland, primarily fruit orchards and hay land, exists on both the colluvium and the flood plain in the vicinity and is irrigated with water diverted from the Deer Trail Ditch which roughly parallels State Highway 133 along the northern border of the proposed permit area. Detailed site geology (Map 11) and land use information (Map 4) provided within the application with regard to the colluvial deposit is limited to an area extending approximately 1,500 feet in all directions from the proposed permit boundary. An evaluation of the colluvial deposit with respect to alluvial valley floor inclusion will be limited to that portion of the deposit mapped as Qc (unconsolidated colluvium) on Map 11. Construction of the loadout pad and haul /access road within the permit area has disturbed approximately 13 acres, primarily orchard land. Surface disturbances have been limited to the colluvial deposit, with no surface disturbance in the present flood plain. No further surface disturbance is proposed. The application describes the unconsolidated deposit as being composed of colluvial material resulting from mass wasting and slope wash from the steep slopes rising to the north of the permit area (see Map 11). The text indicates that, since settlement in the early 1900's, the area was graded to allow construction of the Fire Mountain Canal and accommodate flood irrigation. 20
