The revised drawings show a the final grades reduced to <br />1120 feet, based on 5H:IV slopes with a top area with a minimum slope of three percent. <br />The elevation cited includes the final cover. <br /> <br />The reduction in elevations reduces the volume for the facili .ty by 726,200 cubic yards, as <br />described in the Long-Term Development Plan, from 13,871,600 cubic yards to 13,145,400 <br />cubic yards. <br /> <br />All the drawings are attached. The final grading plan and the cross sections are revised <br />to show the reduced elevations. These sheets supersede the previous submittal. If you <br />have any questions, please call. Eighteen copies are provided, three with full-sized <br />sheets. <br /> <br /> Sincerely, <br /> CAMP, DRESSER & McKEE, INC. <br /> <br />/~hn Cannon, P.E. <br />Project Manager <br /> <br />CC: <br /> <br />Vickie K_reger, Elk River Landfill, Inc. <br />Debra McDonald, USA Waste <br />David Lucas, Sherburne County <br />Matt Ledvina, B.A. Liesch Associates <br />Bill Armstrong, MPCA <br /> <br /> <br />
