Im <br />fiA .;n, =m=gt Practices for Erosionand Sediment Control <br />to <br />(5W BMP 2.04) <br />Definition <br />V <br />Minimizing nonpoint source poliution.from construction sites through good management <br />and "housekeeping" techniques. <br />w <br />Pur ose <br />To reduce the availability of construction -related pollutants which can contaminate runoff <br />waterand, where runoff contamination. cannot be avoided, to retain pollutants andpolluted <br />water on the site. <br />Conditions Where Pract'sce Aaalies <br />This practice applies to all construction projects. The level ofplanning and management <br />necessary to' control nonpoint source pollution adequately is dependent upon the size and <br />complexity of the construction site. ' <br />it <br />Planning Considerations <br />Construction activities, by their nature, create many sources of potential pollutants which <br />can contaminate: runoff and thereby affect the quality of downstream receiving. waters. <br />Accelerated' erosion and sedirrientatip.n caused by land -disturbing activities are the major <br />poll.utlon:problems caused.by construction <br />There are, however,.many other potential pollutants.associated with construction activities <br />r <br />such as gasoline, oils, grease, paints, cements, and solvents, to name only a few. Even <br />relatively non-toxic materials such as paper and cardboard can be classified as potential <br />pollutants when they are washed into streams and lakes. <br />■. <br />The best way to prevent nonpoint. source pollution on construction sites is to use "gocd <br />housekeeping practices, which usually entails. simply ma <br />intaining`tFie site in a neat. and <br />orderly condition. Specific practices "should be employed to.retain runoff and to deal wish <br />toxic substances and materials. An overall plan for the control of nonpoint source pollution <br />is advisable so that control measures can be specified and implemented effectively. <br />Following are some elements which should be considered in nonpoint source pollution <br />control planning on a constriction site: <br />r. <br />1) Erosion and Sediment Controls <br />,. Practices which minimize erosion and retain sediment on site are effective in controlling <br />many other nonpoint source pollutants associated with- construction activities as well. <br />Development and implementation of a good erosion and sediment control plan is a key <br />., factor in controlling nonpoint source pollutants other than sediment on a construction site. <br />
