Thank you for your timely submittal. Monitoring on North Thompson Creek was <br />conducted with the correct frequency and parameters. The parameters include; pH, Total Dissolved <br />Solids, Total Suspended Solids, Bicarbonate, Calcium, Chloride, Iron, Magnesium, Manganese, Sodium, <br />Sulfate, Zinc, and Copper. Sampling was conducted in May and September of 2014. The samples are in <br />compliance with the current monitoring program of the approved permit application (page 3-86). No <br />water discharged from 001 to North Thompson Creek during 2014. All the water was contained in Pond 9 <br />and the Refuse Pond. Seepage water from the No. 1 Mine was not sampled because the water is <br />maintained on site. <br />The Division finds the 2014 Annual Hydrology Report to be in compliance with the Rules and the approved <br />permit application. The Division has no questions or further comments. If you have any questions, please <br />contact me at (303) 866-3567 x8144. <br />Sincerely, <br />Clayton Wein <br />Environmental Protection Specialist <br />pF cp1 <br />�w-\ <br />�¢ "V �9d <br />0 <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining. state. co. us <br />l <br />�* <br />John W.
