Lone Tree Creek flows directly into the Pierre Pit and has flooded the <br />pit. It would exit to the south with high water. <br />2. Topsoil is being stored at the southwest corner of the mine. <br />3. There exists a pile of concrete/dirt to the southwest. <br />4. Vegetation consists of willows some grasses and considerable weedy species. <br />S. There exists an asphalt plant waste pile and some trash near the old hot <br />plant site. <br />6. Pit slopes are probably too steep at the northeast and the south and <br />southwest portions of the pit. <br />7. Grading is excellent to the north and northwest; topsoiling has not yet <br />occured. <br />RECOMMENDATIONS: <br />1. The Division recommends burial of any materials from the concrete/dirt <br />pile not used during the course of mining. <br />2. Final seeding should help improve the vegetation diversity. The operators <br />suggestion to plant seedling willows or cottonwoods is excellent. <br />3. The plans to utilize the asphalt plant waste pile are good and will serve <br />to eliminate the pile. <br />4. Trash should be removed or buried if feasible. <br />5. It is realized that the slopes are steep in areas yet to be mined. Please <br />be sure that slopes are 3:1 or less when grading is complete. <br />6. Topsoil should be distributed over those areas graded to final <br />configuration. <br />7. Please submit the new maps and letter response as discussed in the field. <br />It was good to meet with you and your cooperation is appreciated. Please feel <br />free to call with any concerns or questions. <br />al <br />
