The monitoring program includes the requirements of <br />Colorado Discharge Permit System Industrial General Permit Facility Number COG- <br />850009 (CDPS Permit). Copies of Quarterly Discharge Monitoring Reports have been <br />provided, under separate cover, to the Division at the same schedule required by the <br />CDPS Permit. They are included in this report by reference. The sediment ponds were <br />reclaimed during the fourth quarter 2008. <br />MINE WATER <br />The mine was sealed in 1986.
