For example, materials should be stored and handled is covered areas whenever possible to prevent contact with stormwater; fuels and other chemicals should be stored within berms or secondary containment devices to prevent leaks and spills from entering stormwater runoff. 3) Erosion and Sediment Controls - Describe BMPs that will be used to reduce erosion and prevent sediment delivery to State waters. These should include structural (such as silt fences, sediment ponds, drop structures, chxk dams) and non-structutal (such as mulching and revegetation) methods. 4) Testin¢ for Nonstormwater -The Stormwater Quality Controls section of the SWMP shall include documentation that the discharges have hem tested or evaluated for the presence of non-stormwater discharges each as mine drainage, spoil springs, sanitary waste, or process water of any kind. The dacummtation shall include a description of the results of any test for the presence of non-stormwater discharges, the method used, the date of nay testing, sad the on-site drainage points that were directly observed during the test.

Structural stormwater management measures, eadiment end control measures, and other structural pollution prevention ~Pa~,~ identified in the plan shag be observed to ensure that they are operating correctly. A visual inspection of equipment needed to implement the plan, such as spill response equipment, shag be made. b. Based on the results of the insyactioa, the description of potential pollutant sources and pollution prevention measures identified in the plan shall be revised as appropriate within two weeks of such inspxtion.
