Mr. Murray <br />Page 2 <br />April 14, 2015 <br />3. The Division received comments from the Colorado Historical Society. -The letter has been <br />attached for your review. Please address the comments noted in the letter, and make any <br />changes in the application as necessary. <br />6.4.1 Exhibit A — Legal Description <br />No comment. <br />6.4.2 Exhibit S — Index Map <br />No comment. <br />6.4.3 Exhibit C — Pre - mining and Mining Plan Map(s) of Affected Lands <br />No comment. <br />6.4.4 Exhibit D — Mining Plan <br />4. The Mining Plan calls for seeding fines stockpiles if they are in left in place for more than <br />two years. In the Division's experience topsoil medium can be most effectively salvaged if <br />the stockpiles are seeded if they are left in place for more than one year. Please commit to <br />seeding the topsoil and fines stockpiles if left in place for more than one year or provide a <br />justification for seeding the stockpiles after two years. <br />5. The Operator is proposing to replace salvaged fines as well as available topsoil from <br />undisturbed areas. Please confirm that topsoil will be replaced on the same areas from which <br />it was salvaged. In addition, please commit to not mixing fines and topsoil when the <br />materials are returned to the graded areas. <br />6. The Mining Plan for the gold operation calls for salvaging an average of 4.5 inches of topsoil <br />from undisturbed areas and the Mining Plan for the gravel operation calls for salvaging 4 <br />inches of topsoil from undisturbed areas. Please clarify why an average of 4.5 inches will not <br />be salvaged from the gravel operation area. <br />7. The Mining Plan calls for replacing 3 inches of fines over the gravel mine area. The Division <br />recommends replacing an average of 4.5 inches of fines over the gravel mine area, which is <br />the average depth of native topsoil on the site. The Operator has stated approximately 25,000 <br />cubic yards- of fines have been stockpiled, which would allow for fines to be replaced at a <br />greater depth. Please respond. <br />8. The topsoil handling plan for the gravel operation states that the former 110 area of 11.8 <br />acres has been regarded and will be reclaimed using fines from the stockpiles on site. The <br />Reclamation Plan for the gravel operation states that as of 2014 the former 110 area of 11.8 <br />
