<br />4.3 Erosion and Sediment Controls <br />The site access point will be paved to prevent carrying dirt and materials onto the county road. <br />The interior haul routes will be stabilized by water applications for the life of the mine. The <br />routes outside the active mining azea will be revegetated or maintained as access for the future <br />lakes. <br />Stockpiles have the potential for releasing sediment to stormwaters. Topsoil and overburden <br />material generally is kept so that a reserve is available for the anticipated use during the current <br />yeaz. This practice minimizes the amount of disturbed ground surface, which would be <br />susceptible to erosion by stormwater runoff. All topsoil and/or overburden stockpiles will be <br />seeded with a fast growing cover crop to protect them from wind and water erosion, in the event <br />they aze to be left undisturbed for more than one growing season. The stockpiles will also have <br />erosion control ditches cut at the base to prevent the transport of sediment. A detail of the ditch <br />is included at the end of this narrative. <br />Revegetation of disturbed azeas remains the most efficient and economical Best Management <br />Practice (BMP) for reducing sediment transport from lazge azeas. Roots hold soils in place and <br />surface growth filters sediment and reduces runoff velocities causing deposition of suspended <br />soil particles. <br />Reclamation and vegetating disturbed areas will be an ongoing process to reduce soil erosion at <br />the site. Revegetated azeas will be mulched following seeding to prevent erosion prior to the <br />establishment of the plants. <br />Mowing will provide the predominant form of weed control and appropriate chemicals will only <br />be used to control particulazly hazdy vazieties of weeds. Any weed killers used must be <br />compatible with use neaz waterways. For example, Roundup should not be used neaz running <br />water. <br />4.4 Inspection and Maintenance <br />Preventative inspections for the vehicles located on site will occur on a daily basis. All vehicles <br />will be checked for signs of leaks or other potential problems. Any problems identified will be <br />corrected immediately. Monthly monitoring inspections of the vehicles will be conducted and <br />documented on the attached forms. Preventative maintenance for all the equipment will be <br />conducted on a regulaz basis and documented on the same forms. <br />Preventative inspections for the crushing and screening equipment and the asphalt plant and <br />concrete plant will be conducted on a monthly basis. Any information regarding maintenance <br />needed or performed will be noted on the attached forms. <br />4 <br />
