Depth is determined by water table elevation. Actual depth <br />1 may differ somewhat than shown on the map. A slight basin is allowed in this area. <br />I <br />a. I� 4614.6 I 2.

Reserve Overburden Supply area will remain in the premining condition unless overburden is needed for <br />backfill. Then overburden may be excavated to an elevation equal to the high point elevation of the pit edge to <br />1 I 1 the south. Slopes will be 3:1 to 5:1. No basin will be created in this area without prior approval. Revegetate to <br />it —I grassland using upland grass mixture. <br />4. Topsoil shall be spread along the edge of the reservoir to the anticipated elevation of the reservoir water <br />, level. It is expected that the highest water level will be at about the 4600' contour, but this may vary depending <br />f' on desires of the reservoir owner, safety issues, and storage design. Revegetate to grassland using lakeshore <br />mixture. <br />5. Remove any check dams placed in drainage along east side of Phase 2, unless keeping the check dams <br />would serve some useful purpose. Pueblo County planning may want them to remain. <br />FI <br />6.
