~' ~:t., <br /> <br />BEST MANAGEMENT PRACTICES <br />At least fifteen days before a federal licensee or permittee commences any project <br />in a watercourse, which project may adversely affect water quality, it shall notify the <br />following: <br />A. Applicable local health department; <br />B. Owners or operators of municipal and domestic water supply intakes which <br />are located within twenty miles downstream from the site of the project; and <br />C. Owners or operators of other intakes or diversions which are located within <br />five miles downstream from the site of the project. <br />u <br />2. Construction operations in watercourses and water bodies shall be restricted to <br />areas specified in the federal license or permit. <br />3. Permanent erosion and sediment control measures shall be installed at the earliest <br />practicable time consistent with good construction practices and shall be <br />maintained as necessary throughout the operation of the project One of the first <br />construction activities shall be the placement of permanent and temporary erosion <br />and sediment control measures around the perimeter of the project or the inifial <br />work areas to protect the project water resources. <br />4. Temporary erosion and sediment control measures shall be coordinated with <br />permanent measures to assure economical, effective, and continuous control <br />throughout the construction phase and during the operation of the project. <br />5. Work should be carried out diligently and completed as soon as possible. <br />6. The use of chemicals such as soil stabilizers, dust palliatives, sterilants, growth <br />inhibitors, fertilizers, deicing salts, etc., during construction and operation should <br />be .limited to the best estimate of optimum application rates. Alf reasonable <br />measures shall be taken to avoid excess application and introduction or chemicals <br />into the waters. <br />7. Measures shall'be taken to prevent spilled fuels, lubricants, or other toxic materials <br />from entering the watercourse. <br />8. Whenever practicable, discharges of dredged or fill materials shall be conducted <br />during low flow periods, during periods when spawning is not occurring and during <br />periods when recreational use is relatively low. if such discharges will occur when <br />water temperatures are near freezing and where a domestic ~.vater supply diversicn <br />is located within twenty miles downstream, the permittee shall coordinate with the <br />water purveyor in order to minimize impacts on treated water quality. <br />9. Solids, sludges, dredged, stockpiled or other materials which are potential sources <br />of toxic pollutants, shall be controlled in a manner so as to prevent such materials <br />
