<br />-2- <br />hen mining below the water table, the potential for ground water <br />contamination due to fuel and chemical leaks, waste disposal, etc, <br />can be significant. Provide assurance that the operator will <br />regulate activities to minimize the potential for ground water <br />contamination. <br />6. Will the change in ground water conditions caused by mining this site <br />adversely affect any vegetation in the area such as cottonwood trees <br />which depend on present ground water levels for survival? Should <br />adverse affects occur, how will they be mitigated? The staff <br />suggests irrigating the affected vegetation during periods of pit <br />dewatering; i.e. dewater via 6" mainline pipe into cottonwood grove <br />by opening valve risers. <br />Exhibit E - Reclamation Plan <br />If ponds are part of the reclamation plan and wildlife habitat is the <br />proposed future land use, shorelines should be irregularly shaped to <br />promote a diverse wildlife habitat. Illustrate on Exhibit F that the <br />o ponds will have irregularly shaped shorelines. <br />Provide assurance that the crusher and processing area will be <br />topsoiled and revegetated with all material piles leveled. <br />3. The Department of Wildlife recommends that some trees and shrubs <br />should be used around the pond areas and perimeter of the project, <br />Please incorporate these suggestions into your reclamation plan by <br />providing species and planting rates. Contact the Department of <br />Wildlife for specific recommendations. <br />4. The following items need to be addressed in the reclamation plan: <br />~a! t•~ill the entire terrestrial area be graded to slopes not to <br />exceed 3H:1V? <br />How will the seedbed be prepared? <br />c. What is the seeding method? <br />F~broadcast seeding, you will need to double your seeding rate. <br />at type of fertilizer will be used and what is the rate of <br />pplication? <br />How will weeds be controlled? <br />Exhibit L - Reclamation Costs <br />1. Your estimate of reclamation costs appears to be low. Please add the <br />following items and considerations to your reclamation cost estimate: <br />
