Stormwater BMPs will be constructed and implemented as necessary and directed in <br /> accordance with CO Department of Public Health and Environment's Water Quality <br /> Control Division's stormwater discharge general permit. An armored stormwater <br /> diversion channel will convey surface flow to the south infiltration pond near the natural <br /> ravine should the mine floor elevation become lower than the stream bed elevation. <br /> Storm water infiltration will occur within 72 hours of the precipitation event. All BMPs <br /> will be temporary and will be removed during reclamation. <br /> The target deposits are naturally stratified, during formation. This stratification <br /> creates relief, on a horizontal plane. Drilling, hydraulic breaking, and expansive agents <br /> will be used to continue mining the deposits. Incendiary agents (expansive gases) and <br /> small, isolated explosive cracking or fracturing will only be conducted by qualified <br /> personnel. <br /> 5 <br /> Revised February 10, 2017 <br />
