XIV. Protection of Underground Mining <br /> A. There are no current or proposed surface mining operations within or adjacent to <br /> the Terror Creek Loadout. <br /> XV. Subsidence Control <br /> A. This section does not apply to this operation, as Terror Creek is a coal loadout. No <br /> mining has occurred nor is mining approved to occur. <br /> XVI. Concurrent Surface and Underground Mining <br /> A. This section does not apply to the Terror Creek Loadout. <br /> XVII. Operations on Alluvial Valley Floors <br /> A. Identification of Alluvial Valley Floors <br /> The PAP identifies an alluvial deposit extending approximately one mile to the east <br /> (upstream) and three miles to the southwest(downstream) of the permit area along <br /> the North Fork of the Gunnison River(Map 2 of the PAP). Lands upstream from <br /> the permit area are not a part of the hydrologic system that could be affected by the <br /> Loadout operation; therefore, no determination will be made by the Division for <br /> those lands at this time. <br /> The valley bottom complex in the immediate vicinity of the proposed permit area <br /> (i.e., sections 15 and 22) consists of the current flood plain of the North Fork of the <br /> Gunnison River and a sloping colluvial deposit which rises above the flood plain to <br /> the north. Cropland,primarily fruit orchards and hay land, exists on both the <br /> colluvium and the flood plain in the vicinity and is irrigated with water diverted <br /> from the Deer Trail Ditch which roughly parallels State Highway 133 along the <br /> northern border of the permit area. <br /> Detailed site geology (Map 1) and land use information (Map 4)provided within <br /> the PAP, with regard to the colluvial deposit, is limited to an area extending <br /> approximately 1,500 feet in all directions from the proposed permit boundary. An <br /> evaluation of the colluvial deposit with respect to alluvial valley floor inclusion <br /> will be limited to that portion of the deposit mapped as Qc (unconsolidated <br /> colluvium) on Map 11 of the PAP. <br /> Construction of the Loadout pad and haul/access road within the permit area has <br /> disturbed approximately 13 acres,primarily orchard land. Surface disturbances <br /> have been limited to the colluvial deposit, with no surface disturbance in the <br /> present flood plain. No further surface disturbance is proposed or approved. <br /> The PAP describes the unconsolidated deposit as being composed of colluvial <br /> - 19 - <br />
