Cattany <br />g, Director <br /> Natural Resource Trustee <br />RE: Trapper Mining, Inc., Permit C-81-010 <br />Second Quarter 2008 Discharge Monitoring Reports Review <br />Dear Mr. Roberts, <br />The Colorado Division of Reclamation, Mining, and Safety (CDRMS) has reviewed and found the <br />above referenced report to be in compliance with Rule 4.05.13(2). The Second Quarter Discharge <br />Monitoring Reports were received by the Division on 28 July 2008. The reports cover the time period <br />from 01 April 2008 through 30 June 2008. <br />Seven NPDES outfalls discharged during the Second Quarter of 2008. Outfalls 001, 002, 011 and 020 <br />discharged throughout the quarter. Outfall 013 discharged part of April and again in May due to <br />precipitation events in the form of snowmelt. Outfall 014 recorded discharge once during the quarter <br />due to snowmelt. Outfall 021 discharged due to snowmelt and pit pumping. Outfalls 011, 020, and <br />021 were sampled for WET analyses during the quarter. No exceedances of WET test limitations were <br />observed. <br />It is noted that primary effluent limitations of TSS were exceeded at outfalls 002 and 014 during the <br />quarter primarily due to winter snowpack melting. Based on a Memorandum of Understanding <br />between the Division of Reclamation, Mining and Safety and the Water Quality Control Division <br />(WQCD), the WQCD will be responsible for enforcing CDPS permit conditions including exceedances <br />of TSS. <br />Thank you for the timely submittal. <br />If you have any questions feel free to contact me.
