PART I <br />Page 8 <br />Permit No. COG-500000 <br />C. EFFLUENT LIMITATIONS AND CONDITIONS - STORMWATER DISCHARGE <br />2. Stormwater Management Plan (SWMP) (continued) <br />4) Identification of Discharges other than Stormwater - The stormwater conveyance system on the site shall be evaluated <br />for the presence of discharges other than stormwater, such as mine drainage, spoil springs, sanitary waste, or process <br />water of any kind. The SWMP shall include a description of the results of any evaluation for the presence of <br />discharges other than stormwater, the method used, the date of the evaluation, and the on-site drainage points that <br />were directly observed during the evaluation. <br />A number of discharges other than stormwater may not require a CDPS Industrial Wastewater Discharge permit and <br />are considered Allowable Non-Stormwater Discharges. Flows from fire fighting activities, landscaping irrigation <br />return flow or springs (except spoil springs) that are combined with stormwater discharges associated with industrial <br />activity must be identified in the SWMP. <br />Facility hMctions <br />Qualified personnel identified by the operator shall make a comprehensive inspection of their stormwater management system, at <br />least twice per year (in the spring and fall), except as provided in paragraphs d and e, below. These comprehensive inspections must <br />be documented and summarized in the Annual Report (see Part I.D.4 of the permit), <br />a. Material handling areas, disturbed areas, areas used for material storage that are exposed to precipitation, and other potential <br />sources of pollution identified in the SWMP in accordance with Part I.C.2 of this permit shall be inspected for evidence of, <br />or the potential for, pollutants entering the drainage system Structural stormwater management measures, sediment and <br />control measures, and other structural pollution prevention measures identified in the plan shall be observed to ensure that <br />they are operating correctly. A visual inspection of equipment needed to implement the plan, such as spill response <br />equipment, shall be made. <br />b. Based on the results of the inspection, the description of potential pollutant sources and pollution prevention measures <br />identified in the plan shall be revised as appropriate within two weeks of such inspection. Such revisions shall provide for <br />implementation of any changes to the plan in a timely manner, but in no case more than 60 days after the inspection. <br />C. A report summarizing the scope of the inspection, personnel making the inspection, the date(s) of the inspection, major <br />observations relating to the implementation of the SWMP, and actions taken in accordance with paragraph (b), above, shall <br />be made and retained as part of the SWMP for at least three years. The report shall be signed in accordance with Part I.D.9 <br />of this permit. <br />d. Where semi-annual site inspections are shown in the plan to be impractical for sites where an employee is not stationed or <br />does not routinely visit the site, inspections as required in this part shall be conducted at appropriate intervals specified in the <br />plan, but never less than once in two years. <br />e. Where semi-annual site inspections are shown in the plan to be impractical for inactive sites (sites where industrial activity is <br />no longer conducted), site inspections required by this part shall be conducted at appropriate intervals specified in the plan, <br />but, in no case less than once in three years. At lease one site inspection required under this part shall be conducted before <br />October 1, 1999 or the date two years after such site becomes inactive, whichever is earlier. <br />Additional SWMP Requirements <br />a. Signatory Requirements: A copy of the plan shall be signed in accordance with Parts I.C.6 and I.D.9, and retained on site. <br />b. SWMP Review/Changes: Upon review of the SWMP, the Division may notify the permittee at any time that the plan does <br />not meet one or more of the minimum requirements of this permit. After such notification, the permittee shall make changes <br />to the plan and shall submit to the Division an update to the plan including the requested changes. Unless otherwise provided <br />by the Division, the permittee shall have 30 days after such notification to both make the necessary changes to the plan and to <br />implement them. The permittee shall amend the plan whenever there is a change in design, construction, operation, or <br />maintenance which has a significant effect on the potential for the discharge of pollutants to the waters of the State, or if the <br />SWMP proves to be ineffective in achieving the general objectives of controlling pollutants in stormwater discharges <br />associated with industrial activity. The Division in the same manner as described above may review amendments to the plan. <br />It is the'pernittee's responsibility to notify the Colorado Division of Minerals and Geology (formerly the Mined Land <br />Reclamation Division) of any significant changes at their site resulting from the implementation of the SWMP.
