PARTI Page 9 Permit No. COG-500000 C. EFFLUENT LIMITATIONS AND CONDII7ONS - STORDIH'ATER DISCHARGE 1) SWMP Administrator -The SWMP shall identify a specific individual or individuals within fire mining organisation who is responsible for developing We SWMP and assisting the mine operetor in its implementation, maintenance, and revision. 2) Materials Handlin¢ and Soill Prevention -Where materials can impact slormweler runoff, BMPs that reduce the potential for contamination shall be described. For example, matenals should be stored end handled in covered areas whenever possible to preveal contact with stormwater; fuels and other chemicals should be stored within berms or secondary containment devices to prevent Ieak6 and spills from entering stormwattr 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, check dams) and non-structural (such as mulching and revegetalion) methods. 4) Testin¢ for Non-Stormwater -The Stormwater Quality Controls section of the SWMP shall include documentation that the discharges have been tested ar evaluated for the presence of non-stormwater 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, and the oo-site dreinage points that were directly observed during the test. Except for flows from fire fighting activities, sourrxs of landscaping irrigation retttm (low or springs (except spoil springs) that are combined with stormwater discharges associated with industrial activity must be identified in the plan. 3. Facility Inspections Qualified personnel identified by the operator shall make a comprehensive inspection of their stormweter management system, at least twice per year (in the spring end fall), except as provided in paregrephs d and e, below. These comprehensive inspections must be documented and summarised in the emus! report (see Part 1.D.4 of the permit). a. Material handling areas, disturbed areas, areas used Cor material storage that are exposed to precipitation, end other potential sources of pollution identified in the SWMP in accordance with Part I.C.2 of this permit shall be inspected for evidence of, or We potential for, pollutants entering We drainage system. Structural slormweler management ~++~-r•~res, sedimeut and control measures, and other structure! pollution prevention measures identified in We plan shall be observed to ensure that they are operating correctly. A visual inspection of equipment needed to implement the plan, such as spill response equipment, shall be made. b. Based on We results of the inspection, the description of potential pollutant sources and pollution prevention 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 roamer, but in no case more Wan 60 days after the inspection. c. A report summarising We scope of We inspection, personnel making We inspection, We date(s) of We inspection, major observations relating to We implementation of We SWMP, end actions taken in accordance wiW paregreph (b), above, shall be made and retained as part of We SWMP for at least three years. The report shall be signed in accordance wiW Part I.D.10 of this permit. d. Where semi-annual site inspections are shown in We plan to be impractical for sites where an employee is not stationed or does not routinely visit We site, inspections as required in this part shall be conducted et appropriate intervals specified in We plan, but never less than once in two years.
