Stover and Associates <br />2352 North 7th Street, Unit B <br />Grand Junction, CO 81501 <br />RE: McClave Canyon Mine, C-1980-004 <br />4111 Quarter 2018 Discharge Monitoring Reports Review (CO -0038342) <br />Dear Mr. Stover, <br />The Colorado Division of Reclamation, Mining and Safety (the Division) has finished <br />reviewing the 2018 4`h Quarter Discharge Monitoring Reports for the McClave Canyon <br />Mine. The reports were received via email on November 21, 2018 (October report), <br />December 3, 2018 (November report) and January 7, 20I9 (December and quarterly <br />reports). The reports cover the time period of October 1, 2018 through December 31, <br />2018. The Division finds the reports to be in compliance with Rule 4.05.13(2). <br />There are three outfalls associated with the CO -0038342 DMR permit, Outfall 001, <br />Outfall 002 and Outfall 004. During the month of October, a large storm event in the <br />area of the mine occurred. Outfalls 001 and 004 recorded discharges. Outfall 002 did not <br />record discharging in October. Outfall 001 exceeded the limits for Total Recoverable <br />Iron and TSS (Total Suspended Solids). Outfall 004 recorded an exceedance of Total <br />Recoverable Iron. No other exceedances were recorded. Outfalls 001, 002 and 004 <br />reported no discharge in the months of November and December. The operator expanded <br />the sumps up gradient of the outfalls to allow for lengthened settling times before runoff <br />reaches the outfalls. <br />This concludes the Division's review of the 4'h Quarter 2018 Discharge Monitoring <br />Reports for the McClave Canyon Mine. If you have any questions or concerns, feel free <br />to contact me. <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us <br />Jared Polis, Governor I Virginia Brannon, Director <br />d�:�Olo <br />I E <br />* 1876 <br />
