<br />C. EFFLUENT LIMITATIONS AND CONDITIONS - STORMWATER DISCHARGE
<br />Stormwater Manaeement Plan (SWMP) (continued)
<br />4) IdentificationofDischareesotherthanStortnwater-Thestormwaterconveyancesystemonthesiteshallbeevaluated
<br />for the presence of dischazges ocher than stormwater, such as arine drainage, spoil springs, sanitary waste, or process
<br />water of any kind. The SWMP shall include a description of the resulss of any evaluation for the presence of
<br />dischazges other than stotmwater, the method used, the date of the evaluation, and the on-site dainage poinss that
<br />were dtrectly observed during the evaluation.
<br />A number of discharges other than stormwater may not require a CDPS Industrial W astewater Dischazge permit and
<br />aze considered Allowable Non-Stormwater Discharges. Flows from fire fighting activities, landscaping irrigation
<br />rettun flow or springs (except spoil springs) that aze combined with stormwater discharges associated with industrial
<br />activity must be identified in the SWMP.
<br />3. Facilirv Inspections
<br />Qualified personnel identified by the operator shall make a comprehensive inspection of dteir stormwater management system, at
<br />least twice per yeaz (in the spring and fall), except as provided in paragraphs d and e, below. These comprehensive inspections ffirst
<br />be doctunented and sr~*++**+~*i~ed in the Annual Report (see Part I.D.4 of the permit).
<br />a. Material handling aeeas, disturbed areas, aeeas used for material storage that are exposed to precipitation, and other potential
<br />sources ofpollution identified in the SWMP in accordance with Part I.C.2 ofthis 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 steal] be observed to ensure that
<br />they aze operating correctly. A visual inspection of equipment needed to irttplement the plan, such as spill response
<br />equipment, shall be made.
<br />b. Based on the results of the itspection, the description of potential pollutant sources and pollution prevention treasures
<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 phm in a timely manner, but in no case more than 60 days afrez the inspection
<br />c. A report s,,..,.nar;~;ng 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 aze 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 aze 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 ]ease 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 eazlier.
<br />4. Additional SWMP Requirements
<br />a. Signatory Requirements: A copy of the plan shall be signed in accordance with Parts I.C.6 and 1.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 minim»m requiremenu of this permit. After such notification, the petmittee 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 perrnittee shall have 30 days after such notification to bout make the necessary changes to the plan and to
<br />implement them The pemtittee 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 dischazge 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 descnbed above may review amendments to the plan
<br />It is the permittee'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.
