• The remaining Excess Spoil will be utilized to achieve [he postmining contours shown on Map <br />19. Detailed geotechnical investigations were completed for both the West Pit Fill and the <br />Section 16 Fill by CTL/Thompson, Inc. Reports of the investigations are found in Exhibit 19. <br />Construction plans for [he fills, addressing the requirements of Rule 4.09, Disposal of Excess <br />Spoil, can also be found in Exhibit 19. <br />The topography following mining and reclamation activities is shown on the Postmining <br />Topography Map (Map 19). Cross sections relating the premining and postmining topographic <br />con£gurations are presented as the Premining and Postmining Cross Section Maps (Maps 20 and <br />20A). <br />In the initial permit application, Map 30, Experimental Practice Design, showed the proposed <br />Streeter Fill design. In the current application, the title of Map 30 has been changed to Streeter <br />Fill Design and As-Built, to reflect termination of the Experimental Practice designation, and <br />provide an as-built drawing of the constructed fill. As shown on Map 30, the minor differences <br />between the design and the as-built configuration are insignificant. The primary difference, <br />which increases stability, is the change in the top elevation of the fill from 7300 feet in elevation <br />to 7200 feet. <br />Coal Handling Structures <br />Map No. 1 -Surface ownership shows pre-mining contours and Map 19A -Postmining <br />Topography Gossard Area shows post-mining contours of the loadout. All facilities not to be <br />included as part of the post-mining land use will be removed (see Section 2.05.5). After the <br />• facilities are removed, the land will be regraded to blend with the existing undisturbed <br />topography, retopsoiled and revegetated in accordance with Section 2.05.4. <br />The detailed description of the various coal crushing, handling and loadout facilities for the <br />Colowyo operation is found under the Mine Facilities Section in 2.05.3. The location of the <br />coal processing facilities is found on the Existing Structures -North Map (Map 21) and the <br />Existing Structures -South Map (Map 22). <br /> <br />2.05-37 Revision Date: 5/8/03 <br />Revision No.: TR-56 <br />
