• shown on Map 23A. As such, it is expected that the Section 16 Pit Extension area will be left
open until the South Taylor progressions mine through the area. The postmining topography
for the area is shown on Map 19B.
The following is an updated volumetric summary (in millions) of projected Excess Spoil for
previous and future mining as of December 31, 2006:

Any remaining Excess Spoil would be utilized to achieve the postmining contours shown on Map
• 19. Detailed geotechnical investigations were completed for both the West Pit Fill and the
Section 16 Fill by CTL/Thompson, Inc. Reports of the investigations are found in Exhibit 19.
Construction plans for the fills, addressing the requirements of Rule 4.09, Disposal of Excess
Spoil, can also be found in Exhibit 19.
The topography following mining and reclamation activities is shown on the Postmining
Topography Map (Map 19). Cross sections relating the premining and postmining topographic
configurations are presented as the Premining and Postmining Cross Section Maps (Maps 20 and
20A).
In the initial permit application, Map 30, Experimental Practice Design, showed the proposed
Streeter Fill design. In the current application, the title of Map 30 has been changed to Streeter
Fill Design and As-Built, to reflect termination of the Experimental Practice designation, and
provide an as-built drawing of the constructed fill. As shown on Map 30, the minor differences
between the design and the as-built configuration are insignificant. The primary difference,
which increases stability, is the change in the top elevation of the fill from 7300 feet in elevation
to 7200 feet.

Map No. 1 -Surface ownership shows pre-mining contours and Map 19A - Postmining
Topography Gossard Area shows post-mining contours of the loadout. All facilities not to be
included as part of the post-mining land use will be removed (see Section 2.05.5). After the
facilities are removed, the land will be regraded to blend with the existing undisturbed
topography, retopsoiled and revegetated in accordance with Section 2.05.4.
