Upon final grading and topsoiling, the applicant proposes to reseed with adapted grasses and fortis to achieve a post-mine land use of irrigated cropland. Since the permit area for the Terror Creek Loadout is less than 4D acres in size (20 acres total), the revegetation success standard is based on data collected in 1983 and 1984 from an area immediately west of the loadout. The Division has determined that the area of data collection is topographically and edaphically comparable to the disturbed area. Data submitted has been used by the Division to seta revegetation success standard for production in the reclaimed area at 2,700 lbs./acre (4.15.7 (2) (d) (vi)) YI. Alluvial Valley Floors - Rules 2.06 8 and 4.24 Identification of Alluvial Palley Floors 1. Terror Creek Company 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' 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. _l g_
