Chapfer.4 = Bast_Mana ement_Practices for Erosion and Sediment Control ; <br /> 4 . 02 POLLUTION SOURCE CONTROLS ON CONSTRLICTION SITES <br /> (SW BMP 2 . 04) <br /> Definition <br /> V <br /> Minimizing nonpaint source poliution. from construction sites through goodmanagement <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,. menV 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 neaf. and <br /> orderly condition . Specific practices "should be employed to . retain runoff and to deal with <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 /> 4-3 <br />
