Box 187 <br />Craig, CO 81626 <br />23 January 2019 <br />Re: Trapper Mine (Permit No. C1981-010) <br />Review of 2018 Q2 Discharge Monitoring Reports <br />Dear Mr. Roberts: <br />The Division has received and reviewed Trapper Mines 2018 Quarter 2 Discharge Monitoring <br />Reports (DMRs) for the Trapper Mine. Trapper submits the DMRs to the Division quarterly in <br />accordance with Rule 4.05.13(2)(a)(iii). The Discharge Monitoring Report was received by the <br />Division on 2 August 2018. <br />Trapper reported that outfalls 001, 002, and 011 discharged routinely for the quarter and, that <br />outfall 020 discharged in response to spring snow melt occurring in early April. <br />Trapper reported that primary effluent limitations were exceeded at one outfall during the quarter <br />due to snowmelt response or precipitation events. 10 April samples showed exceedances of TSS <br />and total iron at outfall 020 resulting from heavy precipitation occurring during the period of 6 <br />April through 9 April. <br />The Division does not have any questions or further comments at this time. If you have any <br />questions or need additional information, please contact me. <br />Sincerely, <br />Robin Reilley, M.S.
