Cotter Corporation - C-SR-11 Mine <br /> Stormwater Management Plan - Permit # COR-040029 <br /> February 14, 1994 - Page 5 <br /> 2. By June, 1994, a containment berm will be established to contain potential stormwater <br /> runoff from the Radium 8 Mine site; thus preventing sediment delivery to state <br /> waters. <br /> 3. By June, 1994, a berm will be built along an old exploration road adjacent to <br /> the toe of the Brighton dump. This berm will reduce erosion and prevent sediment <br /> delivery to state waters. <br /> 4. By June, 1994, an existing containment dam northwest of the Tomboy dump will <br /> be cleaned allowing stormwater run-on to be controlled. A silt fence will also <br /> be erected southwest of the Tomboy dump to prevent sediment delivery to state <br /> waters. <br /> 5. The berm along the crest of the Mercantile dump will be re-constructed by June, <br /> 1994. This will assure that all stormwater run-on will be retained within the <br /> waste dump area. <br /> 6. A silt fence will be located south of the Emma Lou dump by June, 1994. This <br /> silt fence will control runoff and prevent delivery of sediment to state waters. <br /> 7. The runoff from the access road to the Ike #3, Ike #4 and the Brighton Mines <br /> is controlled by an existing BMP. This BMP is the short access road into the <br /> Ike#3, which tends to control all runoff to this point. The runoff from the access <br /> road from the Ike #3 to the Ike #4 will be controlled by the silt fence which will <br /> be located south of the Ike #4 dump (see BMP No. 1.) The access road runoff <br /> from the Ike #4 Mine to the Brighton Mine will be controlled by BMP No. 3. <br /> This berm along the old exploration road at the toe of the Brighton dump will <br /> also contain the runoff from the access road, as well as the dump runoff. <br /> g. Employee Training <br /> Employee training aimed at maintaining employee awareness of the stormwater management <br /> plan will be conducted twice per year. This training is anticipated to occur in the <br /> summer and winter of each year. <br /> h. Testing for Non-Stormwater Discharges <br /> Dry weather observations have indicated there are no non-stormwater discharges. <br /> 5. Comprehensive Inspection <br />
