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 /> w <br /> Robin Reilley, M.S.
