--Q� <br /> E URAY-9LvER MuvEs <br /> INTRODUCTION <br /> This SWMP is prepared to mitigate potential impacts to Waters of the U.S. (Sneffels Creek) <br /> resulting from mining and milling operations at the Revenue Mine by Ouray Silver Mines Inc. in <br /> Ouray County, Colorado. As an active mine the measures outlined in this Plan will significantly <br /> improve the stormwater management of the Revenue Mine and as such, will lessen the impact <br /> of sediment laden stormwater to Sneffels Creek, which is the receiving water. This impact is <br /> addressed in this SWMP, as well as the measures taken to mitigate said impact. <br /> DESCRIPTION OF MINING ACTIVITIES <br /> The Revenue Mine is located along Ouray County Road 26 (approximately six miles southwest <br /> of Ouray, CO) at latitude 37.97400' N and longitude 107.75076` W. The site is bordered by <br /> Sneffels Creek to the north and mountains of the San Juan range to the south. The mine area <br /> has been extensively disturbed since the 1880's. <br /> Metal mining operations will be conducted under a DRMS 112D Permit known as the "Revenue <br /> Mine" Permit M-2012-032. Ouray Silver Mines Inc. is permitted for the following uses on the <br /> property: <br /> • Underground mining <br /> • Underground processing of ore <br /> • Surface facilities to support mining activities <br /> • Fuel and Chemical Storage <br /> UNDERGROUND MINING <br /> Ouray Silver Mines personnel operate underground to develop drifts, stopes, and other <br /> excavations for the purpose of producing ore. As part of these activities there will be drilling, <br /> blasting, excavating, and hauling of materials. None of these activities will be exposed to <br /> stormwater runoff. <br /> UNDERGROUND PROCESSING <br /> Operation of an underground processing system for the mined ore will also take place at the <br /> Revenue Mine. This facility is completely constructed underground, and therefore will not be <br /> exposed to stormwater runoff. <br /> SURFACE FACILITIES <br /> An Administration Building and a Dry Miner's Building is used to house offices and provide <br /> lavatories and change facilities for employees. The Mill Building houses the generators, <br /> transformers compressors and essential process equipment. The Warehouse Storage Area <br /> holds consumables and large facility equipment. The Railyard protects the portal and provides a <br /> Stormwater Management Plan 4 1 P a Q e <br />
