3te.cb/.Ytd1xecutive Branch Mail - North Thompson Creek Request for Assistance <br />Tate <br />Of <br />Colofado <br />North Thompson Creek Request for Assistance <br />Bowles - DNR, Brock <brock.bowles @state.co.us> Thu, Jan 3, 2013 at 12:19 PM <br />To: Susan Burgmaier - DNR <susan.burgmaier @state.co.us> <br />Cc: Sandy Brown - DNR <sandy.brown @state.co.us >, Alysha Hernandez - DNR <alysha.hernandez @ state.co.us>, <br />Mary Rodriguez - DNR <mary.rodriguez @state.co.us> <br />Susan, <br />Your assistance is requested to review TR -27 at the North Thompson Creek Mine. <br />The operator would like to occasionally block the primary spillway on Pond 9 that discharges to the approved <br />NPDES discharge point for the purposes of irrigation. When the primary spillway is blocked, Pond 9 will fill with <br />water and discharge through a ditch, irrigating a small parcel of land to the east of Pond 9. The irrigation water <br />will eventually flow to the refuse pond which is the same destination as if the water were discharged through the <br />approved NPDES discharge point. No changes in disturbed area, permit area or affected area are proposed. The <br />structures described in this revision are pre- existing and no new structures are proposed. <br />TR -27 was deemed complete on Jan 3, 2013 and the adequacy question are due to MINREC, Inc. by February 2, <br />2013. 1 would appreciate your comments to me by January 30, 2013. <br />A copy of the revision and maps are available for your review in my office. If you need any further assistance, <br />please ask. <br />Brock Bowles <br />Environmental Protection Specialist <br />Colorado Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />303 - 866 -3567 ext. 8142 <br />https: // mail.google.com / mail / ?ui= 2 &ik= 4546421a5a &vievu =pt& search = inbox &th= l3c01daf8c2Od2dc 1/1 <br />
