hunting." The narrative describes active management for wildlife production including water development and use of prescribed fire. Given the emphasis on wildlife production and management in the Collom expansion area, a designation of Fish and Wildlife Habitat as a joint use along with Rangeland is warranted, pursuant to Rule 1.04(71). In order to provide for a complete application, please amend Map 17 and relevant narrative sections of the application to reflect a Rangeland/Fish and Wildlife Habitat land use designation for the major portion of the expansion area. Further, please delineate the proposed Collom expansion disturbance boundary on the map, to document the extent and location of the different land use types in relation to the proposed disturbance area. b. Rule 2.04.3(2)(a) requires a pre-mining land use map, and Rule 2.05.5 requires a map for post-mining land use. Colowyo has submitted Map 17, it is not clear whether this map is intended to represent pre-mining, post-mining or both. "Surface Mined Lands", labeled "M" on the map, is not a designated land use category pursuant to Rule 1.04(71), and does not reflect pre-mining land use or a proposed post-mining land use. In order to provide for a complete application that conforms with regulatory requirements, Pre- and Post-Mining maps must be clearly represented and the "Surface Mined Lands" category must be replaced with the appropriate pre-mining/post-mining land use designations from Rule 1.04(71). Retention of the stipple pattern on the map to delineate the extent of actual mine disturbance at specified date is appropriate and warranted, along with delineation of the proposed disturbance area boundary associated with the original Colowyo mine and South Taylor expansion. Rule 2.04.6 - Geology Description 6. This item is considered complete. While the Division still has questions regarding the Collom area lithology and the generalized stratagraphic columns, these questions will be handled in the technical adequacy review. 7. This item is considered complete. Colowyo presented the requested data in Exhibit 6, Item 10. The Division may have additional questions regarding the technical adequacy of the materials presented. 8. This item remains incomplete.
