Schemer - - _ <br />Division of Minerals and Geology <br />] 313 Sherman Street, Room 215 <br />Denver, CO. 80203 <br />iii iiiiiiiiiiiu iii <br />999 <br />RECE11/ED <br />APR 0 7 1995 <br />Division of minerals & Geology <br />RE: April 3, 1995 Response Letter to Technical Revision; Mid-Western Aggregates, <br />Inc.; DMG Permit No. M-93-059. <br />Dear Mr Schreiner: <br />We have reviewed your response letter concerning the Mid-Western Farm Technical <br />Revision. We understand the Division's concern that the new proposed phasing plan <br />appears to imply disturbance will increase as the phasing increases. However, the maximum <br />disturbance at any one time will not change from 149.92 acres, as stated in the current <br />permit. <br />The operator has chosen to change the mining direction. The new phasing plan simplifies <br />the operator's direction of the mining plan and is not representative of the maximum amount <br />of disturbance. Therefore, there should be no need to recalculate a new bond amount for <br />each of the four phases. <br />In your response letter you also mention the concern that a 3:1 reclamation slope will be <br />maintained with the use of a suction dredge. There is no difference in the slurry discharge <br />from a clamshell dredge and a suction dredge That is, on the floating dredge whether it is <br />clamshell or suction, the fine material and the water are passed through a screen then <br />pumped into a slurry pipeline. The slurry is discharged on the shoreline. <br />We hope this letter has adequately addressed your concerns regarding the TR submittal. <br />11990 Grant Street, Suite 410 • Denver, Colorado 80233 • (303) 452-6611 • Fax (303) 452-2759 <br />
