1 <br />1 <br /> Minrec, Inc. - Blue Ribbon Mine <br /> stormwater Management Plan <br />' Paqe 2 <br /> b. Risk Identification and Assessment: The stormwater <br /> generated by this operation will potentially contain <br />' sediment. There is no source of process water that could <br /> become mixed with stormwater. There is no outdoor <br /> storage of chemicals or equipment; outdoor milling or <br /> processing activities; historic mine drainage; or <br />' tailings ponds that may contribute pollutants to <br /> stormwater. <br />' c. Preventive Maintenance: Preventive maintenance is <br /> required in the following areas: <br />t 1) Vegetation will be the primary sediment control <br /> feature for stormwater runoff. Vegetation will <br /> filter and reduce the sediment load in the <br /> stormwater. Vegetation will be the sediment <br />' control feature for the three sediment pond <br /> outslopes. If rills occur on the sites, they will <br />' be repaired. Vegetation will be reseeded and <br />mulched if necessary <br /> . <br /> 2) Gravel surfacing will be the primary sediment <br />' control feature for stormwater runoff from the mine <br /> access road. If rills occur on the road, they will <br /> be repaired and gravel surfacing will be replaced. <br />' d. Good Housekeeping: The good housekeeping requirement for <br /> this plan consists of performing the required preventive <br /> maintenance which is the monitoring and maintenance of <br />the vegetation and repair of rills if necessary <br /> . <br /> e. Spill Prevention and Response Procedures: There are no <br />' areas where potential spills could occur outside of the <br /> portion of the operation that contributes runoff to areas <br /> subject to effluent limitation guidelines. <br />' f. Best Management Practices: <br />' 1) There are no areas where stormwater needs to be <br />diverted away from material handling and storage <br /> areas to prevent stormwater contamination. <br />' 2) Materials handling and spill prevention practices <br />are not required because there are no areas where <br />potential spills could occur that would contribute <br />' pollutants to stormwater runoff. <br />3) Sediment and erosion prevention is required in the <br />' following two areas: 1) three sediment pond <br />outslopes; and 2) the mine access road. <br />r~ <br />1 <br />
