Conduct all work in a manner that minimizes turbidity and other disturbances to aquatic resources. 4. Plan temporary construction facilities to: a. Minimize disturbance to stream banks, stream bank vegetation, and the streambed by locating staging or storage facilities at least 50’ horizontally from the highest anticipated water level during construction; b. not restrict or impede fish passage in streams; and c. not restrict any flow anticipated during use. 5. Provide sediment controls for drainage from topsoil stockpiles, staging areas, access roads, channel changes, and instream excavations. 6. Isolate work zones from flowing and standing waters to prevent turbid water and sediments from being discharged into streams or other drainages that flow directly into the stream. Divert flowing waters around the work zone. 7. Do not spill or dump material into streams. Store and handle petroleum products, chemicals, cement and other deleterious materials in a manner that will prevent their entering streams. Site 1.
