<br />COLORADO DEPARTMENT OF HEALTH <br />Water Quality Control Division <br />4210 East 11th Avenue <br />Denver, Colorado 80220 <br />Page 3 of 3 <br />Permit No. COG-850019 <br />VI. DISCUSSION: <br />Applicable effluent limitations and monitoring requirements regarding <br />active mining outfalls and are addressed in Part I.B.1(a) and I.B.3(a) <br />respectively of the general permit. <br />Total dissolved solids monitoring of the discharge shall be performed. <br />Total phosphorus monitoring shall not be performed. See page 3 of the <br />general permit for more information. <br />The Permittee will be required to develop and implement a Storm Water <br />Management Plan (SWMP). Although some activities may already be in place, <br />the SWMP will require the Permittee to coordinate best management <br />practices so the result is a reduction or elimination of pollutants <br />reaching state water from areas not limited by effluent limitations. The <br />Permittee will be required to submit the SWMP to the Division for review <br />within six months from the date certification is issued. For specifics of <br />the Plan and additional requirements, please reference the Part I.B.2 of <br />the general permit. <br />The permittee will not be required to perform Whole Effluent Toxicity <br />(WET) testing pursuant to Section 6.9.7(2)(a)(i)(A) of the Regulations for <br />the State Discharge Permit System 6.1.0 (S CCR 1002-2) which exempts <br />facilities certified under the general permit. <br />VII. SPECIFIC INFORMATION OF CONCERN TO THE PERMITTEE <br />The Permittee is encouraged to read the general rationale for an <br />understanding of how the general permit was developed and to read the <br />permit itself to see what requirements exist.
