Installation, in conjunction with the work previously discussed. The survey covered lands located in Sections 22 and 23, T5N, R87W. No previously recorded sites, isolated finds, or buried cultural materials were found within the surveyed area. Survey results are presented in the Confidential Appendix, in Exhibit 6S. •Sage Creek/Twentymile Overland Conveyor (MR11 =254) — TCC contracted with Metcalf Archaeological Consultants to complete an intensive Class III cultural resources survey of a corridor for a proposed overland conveyor, linking the Sage Creek Mine with the Twentymile Coal Handling Facilities. The survey covered portions of Section 13, T5N, R87W, and Sections 18, 19, 20, 21, 28, 29, and 32, T5N, R86W, and incorporated a number of areas that had been previously surveyed. The survey resulted in recordation of one historic road segment, five previously recorded sites were revisited,. and three isolated finds were documented. The historic road segment is recommended as "non- eligible ", due to historic alteration. One previously recorded site was reevaluated, and the portion within the surveyed corridor is recommended as "non- contributing ". Construction limits or testing are recommended for a second previously recorded site. Survey results are presented in the Confidential Appendix, in Exhibit 6T, Overland Conveyor (MR11 -254) Cultural Resource Information, dated June 2011. RULE 2.04.5 - GENERAL, DESCRIPTION OF HYDROLOGY AND GEOLOGY Each application shall contain a description and ma, prepared in accordance with 2.10, of the geology, surface and ground water systems, including water quality and quantity, of all lands within the proposed permit area the adjacent area and the general area. The description shall include information on the characteristics of all surface and ground waters within the general area, and any water which will flow into or receive discharges of water from the general area The description shall be prepared according to 2.04.5 and 2.04.7 and conform to the following_ (a) Information on surface and groundwater systems including water quality, water quantity, and geology related to the hydrology of areas outside the permit area and within the general area shall be provided by the Division, to the extent that this data is available from an appropriate Federal or State agency. b) If this information is not available from those agencies the applicant may gather and submit • this information to the Division as part of the permit application (c) The permit shall not be approved by the Division until this information is made available in the application. RESPONSE This application contains comprehensive and detailed descriptions and maps concerning the geology and hydrology of the proposed permit area, adjacent area, and the general area. The definitions of these areas, as contained in Rule 1.04, have been applied in what TCC believes to be a reasonable manner to the lands surrounding the planned mining operation. The permit area contains all lands on which the operator will conduct mining operations during the term of the permit. The adjacent area covers lands and resources outside the permit area which may be adversely affected by mining operations. The general area includes the topographic and ground water basin surrounding the area to be mined, including one or more watersheds containing perennial streams and ground water systems. The general area is of sufficient size to allow assessments of cumulative hydrologic impacts in the basin. A strict application of these definitions to Twentymile Park results in the areas shown on Map 4, Proposed Hydrologic Area Boundaries. The proposed permit area includes all lands to be disturbed by mining activities over the life of the Foidel Creek Mine. The proposed adjacent area includes the Twentymile Park ground water basin, including the downstream reaches of the perennial streams of Fish Creek and Trout Creek to the confluence with the Yampa River at Milner. The proposed general area includes the Twentymile Park ground water basin and the watersheds of Fish Creek, Foidel Creek, Middle Creek, and Trout Creek to the confluence with the Yampa River at Milner. Information sufficient for a complete response to this section on the geology and surface and ground water systems for all lands within the general area described above is included under Rules 2.04.6 and 2.04.7 of this • application.
