Cotter Corporation - C-SR-11 Mine <br /> Stormwater Management Plan - Permit # COR-040029 <br /> February 14, 1994 - Page 4 <br /> Beth - The assessment of this dump revealed that the access road to the north <br /> and west of the site prevents stormwater run-on. The flat gradient, porous soils <br /> and extensive vegetative cover prevents stormwater runoff. Accordingly, all potential <br /> runoff is contained within the pit. <br /> 2. Access Roads - The assessment of the access roads revealed that the extensive <br /> vegetative coverage, porous soils and the moderately level grade retains the run <br /> off from two of the three access roads. The third access road which has a potential <br /> for stormwater runoff is the access road to the Ike U3, Ike #4 and the Brighton <br /> Mines. The upper portion of the access road is controlled by existing BMPs, <br /> the lower portion of the access road will be controlled by BMPs which will be <br /> implemented at a later date. <br /> Note: There is no outdoor equipment maintenance or chemical storage at <br /> this site. <br /> c. Preventive Maintenance <br /> Inspections of the stormwater controls will be conducted on a regular basis which is <br /> anticipated to be at least two times per year, or as needed in response to major storm <br /> events. Preventative maintenance will be completed on an as needed basis. <br /> d. Good Housekeeping <br /> The following are some of the good housekeeping practices that are adhered to in order <br /> to minimize the potential for stormwater contamination. <br /> • Garbage and waste materials are picked up and disposed of regularly. <br /> • Spills of oil and petroleum based products are cleaned up in a timely manner <br /> using proper clean-up procedures. <br /> e. Spill Prevention and Response Procedures <br /> In the event ofa spill of significant quantities of materials which could affect stormwater <br /> runoff from this site the SWMP administrator will be notified first. <br /> f. Best Management Practices <br /> 1. By June, 1994, a silt fence will be erected south of the Ike #4 dump to reduce <br /> erosion and prevent sediment delivery to state waters. An existing BMP at this <br /> location is a natural containment dike above the mine dump which prevents stormwater <br /> run-on from entering the dump. <br />
