the eastern limits of the previously surveyed and mined areas. TC has contracted with Metcalf Archaeological <br />Consultants, Inc. to complete intensive Class III cultural resources surveys for any areas subject to potential surface <br />subsidence effects, which have not already been surveyed, as well as any related areas of additional surface <br />disturbance. Generally, these surveys covered limited additional areas in Sections 10, 12, 13, and 14, TSN, R86W. <br />Survey results are presented in the Confidential Appendix, in Exhibit 6L. <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 <br />ground water systems, including water qualily and quantity, of all lands within the proposed permit area, the <br />adjacent area, and the general area. The description shall include information on the characteristics of all surface <br />and around waters within the general area, and any water which will flow into or receive discharges of water from <br />the general area. The description 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 includingwater ater quality, water quantity, <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 a ena. <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 TCC 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 <br />MR15-289 2.04-9.2 09/17/15 <br />
