6.4.4(a) Description of the method(s) of mining to be employed in each stage of the operation as <br />related to any surface disturbance on affected lands <br />Sunrise will initiate the following project activities in accordance with Mine Safety and Health <br />Administration (MSHA) regulations and applicable state and county permit requirements. <br />Phase 1 Construction and Reclamation Activitiesi s <br />A. Access Road and Staging Area Construction: <br />Three equipment staging areas are planned. The three staging areas include areas in close proximity to <br />the Base of Operations, the May Day No. 1 and the May Day No. 2 benches. The Base of Operations will <br />be constructed approximately 50 feet east of County Road (CR) -124. The Base of Operations will be the <br />location where supplies and supporting outside service contractors, chemical storage, fuel, oil products, <br />mine equipment, porta-lets, emergency and safety equipment will be delivered or serviced. <br />The Base of Operations area (Figure D-3) will not store regulated reportable hazardous or toxic <br />chemicals. Small quantities will be stored in a locked chemical storage area within a secondary <br />containment pad. Fuel storage units have been designed with secondary containment capable of holding <br />150% of the volume of the stored product (see Exhibit U for containment details). The Base of <br />Operations will include up to nine parking spaces, in addition to providing room to maneuver field and <br />delivery trucks. <br />The Base of Operations will be bermed and or fenced to limit access, to mitigate potential visual impacts, <br />to reduce potential noise impacts and to improve site security. <br />Equipment and ore staging areas will be located at the May Day No. 1 and May Day No. 2 mine benches. <br />The May Day No. 1 and May Day No. 2 staging areas will be used to temporally store underground mine <br />equipment and supplies. The benches will also be used to temporarily store fuel (with secondary <br />containment), mine rock, potable water, spill response kits, extinguishers, ore and a Port -a -let. <br />B. Grading of existing Roads, May Day No. I and May Day No. 2 benches and Installation of <br />Stormwater Best Management Practice Structures (BMP) <br />Where necessary, the new4 (Figure D-5) and existing access roads will be regraded, truck turnouts will be <br />established (base of Forest Service Access Road and May Day No. 2 portal area) and stormwater BMPs <br />will be put in place and maintained. As necessary, the May Day No.l (Figure D-6), May Day No. 2 (refer <br />to Figures D-7 and D-8) mine benches will be used to temporarily store' ore and mine rock6. <br />Site activities for each affected operating area follow: <br />• Roads (Figure D-5) <br />o Install signs and gates; <br />o Construct berms and crash barriers; <br />2 TR -3 Approved the La Plata Bridge on June 26, 2012 (see Appendix D-1) <br />3 TR -6 -Removed on April 2, 2013, the previously approved Mill from the permit <br />4 Approved TR -2 on May 23, 2012 <br />5 Ore and Rock storage pads are designed with an impermeable clay liner. <br />6 Underground waste rock may be temporarily stored (<180 days) on storage pads while a detailed <br />exploration, development and mine plan are being prepared. <br />
