STORMWATER MANAGEME. .'PLAN 2/20/09 <br />Maryland Creek Ranch <br />SEDIMENT AND EROSION PREVENTION <br />(SWMP TRAINING) <br />1. Mining activities will take place within the pit area, so any stormwater runoff within the pit <br />will stay in the pit. <br />2. Stormwater runoff from raw material stockpiles, product stockpiles, equipment storage <br />and maintenance areas, equipment wash area, employee parking, the concrete and <br />asphalt plants is contained within the processing area. <br />3. The permitted discharge points (noted on the site map) are visually inspected regularly <br />to ensure the water leaving the site is clear of any sediments. <br />4. Topsoil and overburden stockpiles will be seeded and revegetated to prevent erosion. <br />5. Stormwater collected in various settling ponds and retention/detention areas, will have <br />sufficient residence time to allow for settling of sediment. <br />6. The haul roads are stabilized by applying water and compaction with truck traffic. <br />14
