C. The underground workings maps provided with the application shows most of the <br />• workings to be located in the North East portions between the Eclipse and Carbonate Green <br />and very small amounts of workings in the southern portions of the valley leach expansion <br />areas. The Chicago Tunnel, a small 110 permit (M-1988-026) owned by CC&V and currently <br />being used by a sub contractor to CC&V as equipment storage area, is located west of the <br />North Cresson mine expansion area. Where is the underground extension of the tunnel <br />workings in relation to the North Cresson Mine extension? What impacts does CC&V <br />expect from the mining activities proposed in these areas? Please explain. What about <br />impacts to the Molly Kathleen Tourist Mine located northwest of the North Cresson Mine? <br />Response: <br />The underground extension of the Chicago Tunnel ends approximately 25-50 feet inside of the <br />designed North Cresson surface mine. There is no discharge from the Chicago Tunnel portal <br />and the Portal area has been reclaimed and backfilled for over 3 years. Very little impact is <br />expected from intercepting the Chicago Tunnel as it is dry and is expected to be reasonably <br />competent. Similar underground working within the Main Cresson and East Cresson surface <br />mines remain intact and are not impediments to surface mining. <br />No impacts to the Mollie Kathleen underground working are expected to result from mining <br />in the North Cresson mine. The Mollie Kathleen workings are approximately 1,300 feet <br />north-northwest of the designed North Cresson mine and there are no direct connections. <br />CC&V has initiated a blast monitoring program both at the surface and in underground <br />• workings at the Mollie Kathleen to assess potential blasting impacts as CC&V activities move <br />closer to that facility. CC&V will stay in close contact with the Mollie Kathleen management <br />as the North Cresson mining progresses. CC&V will complete a pre-blast survey of the <br />Mollie Kathleen facilities prior to initiating mining in the North Cresson mine area. <br />D. All road alignments required under this amendment and interchange upgrades to County <br />Road 82,821 and highway 67 will require a written approval from the County and CDOT. <br />Please provide the approval letters for our records, once obtained. <br />Response. <br />CC&V is currently working on final designs and associated agreement with Teller County <br />and Colorado Department of Transportation (CDOT) for these road upgrades. Once approval <br />written letters are received from the County and CDOT for the CR 82, CR821 and SH 67 <br />improvements/upgrades, copies of those approval letters will be forwarded to DRMS. <br />E. On Drawing C-5 (Conceptual Mining Phases), the only area being proposed as alternative <br />overburden storage area is the area designated as Squaw Gulch overburden storage <br />extension area by the year 2011. It is not clear from the maps or description what the <br />proposed final contours will be for this area. The currently approved final topography will <br />not allow the operator's over all elevation to exceed 10,600 feet. As noted in drawing C-4 <br />and F-1, elevations appear to exceed the allowable limit under AM-08, Is CC&V requesting <br />. an increase in height by approximately 35 feet to 10,635? Please explain. <br />Response: <br />9
