PART I Page 9 Permit No. COG-500000 C. EFF~I.UENT LIMITATIONS AND CONDITIONS - STORMWATER DISCHARGE 1) SWMP Administrator -The SWMP shall idwtify a specific individual or individuals within the mining orgmvation who is responsible for developing the SWMP and assisting the mine operator in its itnplemcatation, maintenance, and revision. 2) Materials Handling and Soill Prevcation -Where materials can impact stormwater runoff, BMPs that reduce the potential for contamination shall be described. For example, materials should be stored and handled in covered areas whcaever possible to prevcat contact with stormweter, fuels and other chemicals should be stored within berms or secondary contaitunwt devices to prevwt leaks and spills from entering stormwater runoff. 3) Erosion and Sedimwt Controls - Describe BMPs that will be used to reduce erosion and prevent sedimwt delivery to State waters. These should include structural (such as silt fences, sediment ponds, drop structures, check dams) and non-atructwal (such as mulching and revegetation) methods. 4) Testine for Non-Stormwater -The SWrmwater Quality Controls section of the SWMP shall include documentation that the discharges have been tested or evaluated for the preswce of non-stormwater discharges such as mine drainage, spoil springs, sanitary waste, or process water of any kind. The documentation shall include • desmptioo of the results of any test for the prescace of non-swtmwater discharges, the method used, fhe date of any testing, sod the oo-site drainage points that were directly observed during the test. Except for Flows from fire fighting activities, sources of landscaping irrigation return flow or springs {except spoil springs) that ere combined with stormwater discharges associated with industrial activity must be identified in the plan. aulity Inspection Qualified persomel identified by the operator shall make a comprehensive inspection of their smrmwater management system, at least twice per year (in the spring and fell), except as provided in puagraphs d and e, below. These comprelensive inspections must be documented and sums`~zed in the annual report (see Part I.D.4 of the permit). a. Material handling areas, disturbed areas, arras used for material storage that are exposed W precipitation, sod other potential sources of pollution idcatified in the SWMP in accordance with Part I.C.2 of this permit shall be inspected for evidcace of, or the potcatial for, poflumnts catering the dtaimge system. Structural stormwater manegemcat measures, sediment and control treasures, end other structure) pollution prevcation measures identified in the plan shall be observed W ensure that they are operating correctly. A visual inspection of equipment needed to implemcat the plan, such as spill cespoase equipmcat, shall 6e made. b. Based oo the results of the inspection, the description of potential pollutant sources and pollution prevwtion measures identified in the plan shall be revised as appropriate within two weeks of such inspection. Such revisions shall provide for implementation oCany changes to the plan in a timely mmner, but is no case more then 60 days after the ittspectioo. c. A report summarizing the scope of the inspection, persomel making the inspection, the date(s) of the inspection, major observations relating W the implemcahtion of the SWMP, and actions taken in accordance with paragraph (b), above, shall be made and retained es 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. Where semi-annual site inspections arc shown in the plan m be impractical for sites where ca employce is not stationed or does not routinely visit the site, inspections as required in this part shall be conducted at appropriate intervals specified in the plan, but never less than once in two years.
