2.06 REQUIREMENTS FOR PERMITS FOR SPECIAL CATEGORIES 2.06.1 Scope This Section establishes minimum requirements for permits for the special categories of surface coal mining and operations which are in addition to the applicable permit application requirements and procedures of Rule 2. With the exception of 2.06.8, none of the special categories of surface coal mining and operations are applicable to the TCC proposed operations. 2.06.8 Surface Coal Mining and Reclamation on Areas or Adjacent to Areas Usinq Alluvial Vallev Floors TCC has conducted detailed reconnaissance of the site specific geology and land forms which are present within the permit area and adjacent area of the proposed facilities. Results of this detailed mapping is . shown on the Site-Surface Geology 14ap (Map 11). The permit area and adjacent area consists of colluvial material resulting from mass wasting and erosion of the adjacent Mesaverde formation. As erosion occurred, fractured sandstone, siltstone and shale rocks moved by overland flow and gravity across the Macros Shale formation which underlies the permit and adjacent areas. Since the area was settled in the early 1900's, the area has been graded to accomodate flood irrigation from water provided by the North Fork of the Gunnison River. An alluvial valley floor is present in the adjacent area. The North Fork of the Gunnison River lies in stream laid sediments. The relationship of the permit area with this alluvial valley floor is insignificant in that no disturbance to the alluvial valley floor will occur. TCC respectfully requests that the Division find this area not to be an alluvial valley floor. Specific information which has been provided for this determination includes the following. Detailed mapping of unconsolidated stream laid deposits which hold streams are shown on the Site-Surface Geology Map, (Map 11). The area 2.06-1
