BEST MANAGEMENT PRACTICES <br /> 1. At least fifteen days before a federal licensee or permitlee 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 /> 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 maintained <br /> as necessary throughout the operation of the project. One of the first construction <br /> activities shall be the placement of permanent and temporary erosion and sediment <br /> control measures around the perimeter of the project or the initial work areas to <br /> 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 be <br /> limited to the best estimate of optimum application rates. All reasonable measures <br /> shall be taken to avoid excess application and introduction of chemicals into the <br /> 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 water supply diversion <br /> is located within twenty miles downstream, the permiltee 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 /> (over) .11 <br />
