PART I <br /> Page 29 of 67 <br /> Permit No.: COG500000 <br /> c. If conditions change and the facility becomes active and/or staffed,exceptions under this part no longer apply and the <br /> permittee must immediately resume quarterly visual monitoring and benchmark sampling,and applicable water <br /> quality standards sampling at the frequency identified in the permit certification. <br /> d. The presence of staff at the facility to conduct required facility inspections does not change the inactive and unstaffed <br /> status of the facility for the purposes of this part. <br /> 8. Monitoring Exceptions for Completed and Finally Stabilized Areas <br /> The requirement that permittees conduct and document visual monitoring, benchmark sampling,or water quality standards <br /> monitoring of stormwater discharges does not apply at completed facilities,completed portions of facilities,or finally stabilized <br /> portions of facilities that meet all of the following conditions: <br /> a. All industrial activities(such as mining, processing, batch plant activities,other land disturbing activities,fueling, <br /> loading/unloading etc.)are temporarily or permanently complete in the specified area,where temporarily complete <br /> means that such industrial activities are not currently conducted at the facility, but may recommence in the future; and <br /> b. The permittee has implemented all final stabilization measures(with or without seeding)to enable the specified area <br /> to attain final stabilization,or the specified area has attained final stabilization consistent with Part.I.A.7.a or b of the <br /> permit;and <br /> c. All final stabilization measures are selected,designed, installed,implemented and maintained in accordance with good <br /> engineering hydrologic and pollution control practices such that they effectively reduce pollutant potential and the <br /> potential for control measure failure for the designated area;and <br /> d. The permittee amended the SWMP to identify those areas for which this exception applies,including the date the <br /> areas met the exception conditions. <br /> Stormwater discharges from portions of facilities that are permanently stabilized(i.e.,meet the termination criteria at Part I.A. <br /> 7.b of the permit,or have obtained an Acreage(or partial) Release from the DRMS for that portion of the facility)no longer <br /> require CDPS permit coverage,as the discharge no longer meets the definition of"stormwater discharges associated with <br /> industrial activity"pursuant to Regulation 61.3(2). In such cases,the permittee may request that the division reduce the facility <br /> permit boundary by the relevant portion of the facility. <br /> 9. Revocation of Monitoring Exception <br /> The division retains the authority to revoke any Monitoring Exception identified in this Part where it is determined that the <br /> discharge causes,has a reasonable potential to cause,or contributes to an instream excursion above an applicable water quality <br /> standard,including designated uses. <br /> I. SPECIFIC MONITORING REQUIREMENTS — Stormwater only <br /> 1. Visual Monitoring <br /> Once each quarter for the entire permit term,the permittee must collect a stormwater sample from each outfall (or a <br /> substantially identical outfall pursuant to Part I.H.1 above)and conduct a visual assessment of each of these samples. <br /> a. These samples should be collected in such a manner that the samples are representative of the stormwater discharge. <br /> b. The visual assessment must be made of a sample in a clean,clear glass or plastic container,and examined in a well-lit <br /> area.The permittee must visually inspect the sample for the presence of the following water quality characteristics: <br /> i. Color; <br /> ii. Odor; <br /> iii. Clarity; <br /> iv. Floating solids; <br /> v. Settled solids; <br />
