UNIVERSAL STORM WATER MANAGGNIENT PLAN - 15 DE;CEMBER 1997 <br /> C. Erosion and Sediment Controls: - Sediment is controlled by perimeter ditches and roads <br /> that prevent escape of material due to storm water. Vegetation acts to buffer adjacent lands due to <br /> established set backs. Where barren outslopes [outfall(s)] exist, those areas will be stabilized with <br /> vegetation, mulch, or other traditional soil conservation measures or structures, including hay bales <br /> or other appropriate methods. If necessary, the upper portion of outslopes will be bermed or cut to <br /> divert upland overland flow away from the outslope, limiting it to the influences of direct <br /> precipitation. <br /> Primary concerns will be to control gully and rill erosion on outslope areas, and prevent the <br /> transportation or detached of material from exposed ground originating on internal portions of the <br /> site. Where road surfaces are compact, treatment of those areas will not be necessary since <br /> protection of off-site areas will not be significantly influenced due to the low level of detachment <br /> over these locations. Sediment laden waters flowing over roads will be directed back to internal <br /> portions of the site or onto vegetated buffers or waterways. Roads are relatively flat and do not <br /> support a significant watershed. <br /> Final stability of each site is secured subsequent to extraction operations as part of reclamation <br /> required by DMG. The majority of excavation causes storm water to drain internally. All grades <br /> will be established at 3h:Iv or flatter and will be revegetated to predominantly native vegetation. <br /> Any resulting ponds will be self-contained and possibly lined. <br /> D. Testing for Non-Storm Water: - Unless directed by the Colorado Department of Health, <br /> Testing for Non-Storm Water is not required. Process water is tested according to the terms of <br /> each permit. <br /> IV.
