PARTI Page 9 Permit No. COG-500(100 =. EFFLUENT LIMTTATIONS AND CONDITIONS - STORMWATER DISCHARGE • 1) SWMP Administrator -The SWMP shall identify a specific individual or individuals within the mining orgaai7rtion who is responsible for developing the SWMP and assisting the mine operator in ifs implementation, maintenance, and revision. 2) Materials Haodlin¢ and Soill Prevention -Where materials cea impact stormwater runoff, BMPs that reduce the potential for contamination shall be described. For example, materials should be stored and handled in coveted areas whenever possible to preveht contact with eWrmwater, fuels and other chemicals should lx stored within berme or secondary containment devices to prevent leaks and spills from entering etormwater rtmoff. 3) Erosion and Sediment Controls - Describe BMPs that will be treed to redtrce erosion end prevent sediment delivery to State waters. These should include structural (such as silt fences, sediment ponds, drop structurra, check dams) sad non-strtctural (such as mulching and nvegetation) methods. 4) Testin¢ for Naa-Stotmwater -The Stormwater Quality Controls section of the SWMP shall include documentation that the discharges have been leafed or evaluated for the presence of aonstormwater discharges such as mine drainage, spoil springs, sanitary waste, or process water of any kind. The documentation shall include a description of the results of any test for the presence of non-stormwater discharges, the method used, the date of any testing. sad the oa-site drainage points that were directly observed during the test. Except for flaws from fire fighting activities, sources of Lmdacaping irrigation return flow or springs (except spoil springs) that are combined with stormwater discharges associated with industrial activity must be idenfified is the phm. Facility Inspections Qualified personnel identified by the operator shall make a comprehensive inspection of their stormwater management system, at least twice per year (ia the spring and fall), except as provided in paragraphs d and e, below. These comprehensive inspections must be documented and summarised is the annual report (see Part I.D.4 of the permit). a. Material handling arras, disturbed areas, ones used for material storage that an exposed to precipitation, and other potential sources of pollution identified in the SWMP is accordance with Part I.C.2 of this permit shall be inspected for evidence of, or the potential for, pollutants entering the drainage system. Swctural stormwater management measures, sediment and wntrot measures, atul other structural pollution prevention measures identified in the plan shall be observed to ensure that they ate operating correctly. A visual inspection of equipment needed to irnplemeat the plan, such os spill response equipment, shall be made. b. Based on the results of the inspection, the description of potential pollutant sources and pollution pnvmtian measures identified in the plan shall be revised as appropriate within two weeks of such inspection. Such revisions shall provide for implementation of any changes to the plan in a timely manner, but in no case more thaw 60 days alter the inapxtioa. c. A report summariang the scope of the inspection, personnel making the inspection, the date(s) of the inspection, major observations relating to the implementation of the SWMP, and actions mkm in accordance with paragraph (b), above, shall be made and retained u part of the SWMP for at least three years. The report shall be signed in accordance with Part I.D.10 of this permit. d. When semi-annual site inspections are shown is the plan to be impractical for sites where an employee is not . stationed or does not routinely visit the site, inspections as required in this part shall be conducted at appropriate intervals spxified in the plan, but never less then Dace in two years.
