18 -Left Ventilation Shaft Installation and 16 -Right Stabilization Boreholes (TR09 -66 and MRII -253) -_TC
<br />contracted with Metcalf Archaeological Consultants, Inc. to complete an intensive Class III cultural resources
<br />survey of the proposed 18 -Left Ventilation Shaft Installation, in conjunction with the work previously discussed. A
<br />separate survey addressed planned disturbance for the 16 -Right Mine Stabilization Boreholes. The surveys covered
<br />lands located in Sections 22 and 23, T5N, R87W. No previously recorded sites, isolated finds, or buried cultural
<br />materials were found within the surveyed area. Survey results are presented in the Confidential Appendix, in
<br />Exhibit 6S.
<br />Sage Creek/Twentymile Overland Conveyor (MRll -254) — TC contracted with Metcalf Archaeological
<br />Consultants to complete an intensive Class III cultural resources survey of a corridor for a proposed overland
<br />conveyor, linking the Sage Creek Mine with the Twentymile Coal Handling Facilities. The survey covered portions
<br />of Section 13, T5N, R87W, and Sections 18, 19, 20, 21, 28, 29, and 32, T5N, R86W, and incorporated a number of
<br />areas that had been previously surveyed. The survey resulted in recordation of one historic road segment, five
<br />previously recorded sites were revisited, and three isolated finds were documented. The historic road segment is
<br />recommended as "non - eligible ", due to historic alteration. One previously recorded site was reevaluated, and the
<br />portion within the surveyed corridor is recommended as "non- contributing ". Construction limits or testing are
<br />recommended for a second previously recorded site. Survey results are presented in the Confidential Appendix, in
<br />Exhibit 6T, Overland Conveyor (MR11 -254) Cultural Resource Information, dated June 2011.
<br />15 -Left Rock -Dust Installation and 16 -Left Utility Borehole (TRll -77, TR11-78) -_TC contracted with Metcalf
<br />Archaeological Consultants, Inc. to complete intensive Class III cultural resources surveys of the proposed 15LT
<br />Ventilation Installation and 16LT Utility Borehole. The surveys covered lands located in Sections 23, 24, 25, 26
<br />and 27,T5N, R87W. No previously recorded sites, isolated finds, or buried cultural materials were found within the
<br />surveyed area. Survey results are presented in the Confidential Appendix, in Exhibit 6T.
<br />RULE 2.04.5 - GENERAL DESCRIPTION OF HYDROLOGY AND GEOLOGY
<br />Each application shall contain a description and map, prepared in accordance with 2.10, of the geology, surface and ground
<br />water systems, including, water quality and quantity, of all lands within the proposed permit area, the adjacent area, and the
<br />general area. The description shall include information on the characteristics of all surface and ground waters within the
<br />general area, and any water which will flow into or receive discharges of water from the general area. The description
<br />shall be prepared according to 2.04.5 and 2.04.7, and conform to the following
<br />(a) Information on surface and groundwater systems including water quality, water quantity, and
<br />geology related to the hydrology of areas outside the permit area and within the general area shall be provided by the
<br />Division, to the extent that this data is available from an appropriate Federal or State agency.
<br />(b) If this information is not available from those agencies, the applicant may gather and submit
<br />this information to the Division as part of the permit application.
<br />(c) The permit shall not be approved by the Division until this information is made available in
<br />the application.
<br />RESPONSE
<br />This application contains comprehensive and detailed descriptions and maps concerning the geology and hydrology of
<br />the proposed permit area, adjacent area, and the general area. The definitions of these areas, as contained in Rule
<br />1.04, have been applied in what TC believes to be a reasonable manner to the lands surrounding the planned mining
<br />operation. The permit area contains all lands on which the operator will conduct mining operations during the term of
<br />the permit. The adjacent area covers lands and resources outside the permit area which may be adversely affected by
<br />mining operations. The general area includes the topographic and ground water basin surrounding the area to be
<br />mined, including one or more watersheds containing perennial streams and ground water systems. The general area
<br />is of sufficient size to allow assessments of cumulative hydrologic impacts in the basin.
<br />A strict application of these definitions to Twentymile Park results in the areas shown on Map 4, Proposed
<br />Hydrologic Area Boundaries. The proposed permit area includes all lands to be disturbed by mining activities over
