Section 38-4-15 - Erosion and Sediment Control15.1. Erosion and sedimentation must be controlled to prevent a degradation of land and streams below the dam or project area to prevent any violation of state water quality standards. Erosion and sediment control measures shall, at the minimum, conform with current erosion and sediment control manuals and apply to the entire project area.15.2. Temporary seeding and mulching shall be utilized on areas where no construction activity is anticipated for a period of three (3) or more weeks.15.3. Water Routing: Water that is pumped or drained from work areas such as excavations and foundations must be routed to properly sized sediment control devices so that any sediment contained in water is removed prior to discharge of the water from the project area. Pump discharges may not cause erosion or suspension of additional solids. No untreated water may be pumped or drained to the natural stream or stream diversion channel.15.4. Permanent Erosion measures: Permanent measures e.g. Vegetation, grading, diversion waterways and outlet structures all be included on all completed or existing dams, where applicable to prevent the erosion of embankments, abutments, stream channels and waterways during the life and operation of the dam.
