PART II
<br />Page No. 15
<br />Permit No. COG-850000
<br />d. Materials Handling and Spill Prevention -Where materials can impact stormwater runoff, BMPs that reduce the
<br />potential for contamination shall be described. For example, materials should be stored and handled in covered
<br />areas whenever possible to prevent contact with stormwater; fuels and other chemicals should be stored within .
<br />berms or secondary containment devices to prevent leaks and spills from entering stormwater runoff.
<br />e. Erosion and Sediment Controls -Describe BMPs that will be used to reduce erosion and prevent sediment
<br />delivery to State waters. These should include structural (such as silt fences, sediment ponds, drop structures,
<br />check dams) and non-structural (such as mulching and revegetation) methods.
<br />Whenever a facility or a portion of a facility enters the post-mining phase, it is likely that the overall configuration
<br />of the site will change considerably. Prior to the time when new vegetation becomes established, the surface areas
<br />will be subject to potentially significant erosion. The permittee will need to take adequate measures in order to
<br />minimize this erosion as well as the erosion normally encountered during mining activities.
<br />f. Identification of Discharges other than Stormwater -The stormwater conveyance system on the site shall be
<br />evaluated for the presence of discharges other than stormwater, such as mine drainage, spoil springs, sanitary
<br />waste, or process water of any kind. The SWMP shall include a description of the results of any evaluation for
<br />the presence of discharges other than stormwater, the method used, the date of the evaluation, and the on-site
<br />drainage points that were directly observed during the evaluation.
<br />b. Facility Inspections
<br />Qualified personnel identified by the operator shall make a comprehensive inspection of their stormwater management
<br />system, at least twice per year (in the spring and fall), except as provided in paragraphs d and e, below. These
<br />comprehensive inspections must be documented and summarized in the Annual Report (see Part I.E.2. of the permit).
<br />Qualified personnel, for purposes of site inspections, are those who possess the knowledge and skills to assess conditions
<br />and activities that could impact stormwater quality at the facility, and who can also evaluate the effectiveness of BMPs
<br />selected.
<br />1. Material handling areas, disturbed areas, areas used for material storage that are exposed to precipitation, and other
<br />potential sources of pollution identified in the SWMP in accordance with Part LC.l.a.l. of this permit shall be
<br />inspected for evidence of, or the potential for, pollutants entering the drainage system. Structural stormwater
<br />management measures, sediment and control measures, and other structural pollution prevention measures identified in
<br />the plan shall be observed to ensure that they are operating correctly. A visual inspection of equipment needed to
<br />implement the plan, such as spill response equipment, shall be made.
<br />2. Any repairs or maintenance needs identified by the inspection shall be completed immediately. Based on the results of
<br />the inspection, ifrevisions to the description ofthe potential pollutant sources and the pollution prevention and control
<br />measures identified in the SWMP are needed, the plan shall be revised as appropriate as soon as practicable after such
<br />inspection. Revised control measures shall be implemented in a timely manner, but in no case more than 90 calendar
<br />days after the inspection, unless otherwise provided by the Division.
<br />3. A report summarizing the scope of the inspection, personnel making the inspection, the date(s) of the inspection,
<br />significant observations relating to the implementation ofthe SWMP, and actions taken in accordance with paragraph
<br />(b), above, shall be made and retained as part of the SWMP for at least three years. Significant observations include
<br />such things as the locations of discharges of pollutants from the site; locations of previously unidentified sources of
<br />pollutants; locations of BMPs needing maintenance or repair; locations of failed BMPs that need replacement; and
<br />locations where additional BMPs are needed. The report must also document any incidents of noncompliance
<br />observed. The report shall be signed in accordance with Part I.E.7. of this permit.
<br />4. Where semi-annual site inspections are shown in the plan to be impractical for sites where an employee is not
<br />stationed or does not routinely visit the site, inspections as required in this part shall be conducted at appropriate
<br />intervals specified in the plan, but never less than once in two years.
<br />5. Where semi-annual site inspections are shown in the plan to be impractical for inactive sites (sites where industrial
<br />activity is no longer conducted), site inspections required by this part shall be conducted at appropriate intervals
<br />specified in the plan, but, in no case less than once in three years. At lease one site inspection required under this part
<br />shall be conducted before May 31, 2010, or the date two years after such site becomes inactive, whichever is later.
<br />c. Additional SWMP Requirements
<br />1. Signatory Requirements: A copy of the plan shall be retained on site.
