Box 1303 <br /> Boulder, CO 80306 <br /> Ref: 91131D - Deepe Pit <br /> Dear Mike: <br /> The purpose of this letter is to respond to your request for information on the <br /> potential impacts on reclamation-related earth moving efforts due to the changes <br /> between the previously approved MLRB reclamation plan and the revised plan <br /> currently submitted for review. <br /> The intent of both plans are to balance on-site earthwork quantities. The primary <br /> reasons for the proposed lakes in the original plan was to provide a source for <br /> material (shale) which could be used to meet the proposed reclamation plan grades. <br /> Based on the final mined material volumes and the currently proposed reclamation <br /> plan grades, additional shale excavation is not required in order to obtain materials <br /> to provide an earthwork balance for the site. <br /> In summary, there is significantly less reclamation related earthwork required to <br /> meet the final grade elevations of the currently proposed reclamation plan. This is <br /> the result of maintaining earthwork balances and planning for different final <br /> reclamation grades. <br /> I hope this addresses your concerns. Please don't hesitate to contact us if you have <br /> additional questions. <br /> Sincerely, <br /> SCOTT, COX &ASSOCIATES,INC. <br /> By <br /> William H. Mitze i <br /> cc: Mr. Ed McDowell <br />
