r <br /> Chapter 4 - Best Management Practices for Erosion and Sediment Control <br /> conveyance system . Special areas should be designated for washing vehicles . These <br /> areas should be located where the wash water will spread out and evaporate or infiltrate <br /> directly into the ground , or where the runoff can be collected in a temporary holding or <br /> seepage basin . Wash areas should have gravel bases to minimize mud generation . <br /> 7) Storage of Construction Materials , Chemicals . Etc. <br /> r <br /> Sites where chemicals , cements , solvents , paints , orother potential water pollutants are to <br /> be stored , should be isolated in areas where they will not cause runoff pollution . Toxic <br /> r chemicals and materials, such as pesticides, paints, and acids, should be stored according <br /> to manufacturers' guidelines . Overuse should be avoided and great care should be taken <br /> to prevent accidental spillage . Containers should never be washed in or near flowing <br /> r streams or stormwater conveyance systems. Groundwater resources should be protected <br /> from leaching by placing a plastic mat, tar paper, or other impervious materials on any <br /> areas where toxic liquids are to be opened and stored . <br /> 8) Sanitary Facilities <br /> r All construction sites should be provided with adequate sanitary facilities for workers <br /> according to applicable health regulations . <br /> r 9) Dust Control <br /> The use of calcium chloride, oils , or other chemical dust control agents on construction <br /> r roads should be avoided . Periodic watering of these areas is a preferred alternative . <br /> 10) Dewatering <br /> Many improvements such as underground utilities, foundations, and stormwater <br /> management facilities require removal and disposal of water from excavations . A detailed <br /> ,. discussion of this practice follows in DEWATERING - Section 4 .40 . <br />• <br /> r <br /> 4-5 <br />
