Box 628 WQCD PE-B2 Division <br />°t Mi <br />Nuda, Colorado at4z4 4300 Cherry Creek Drive South nwals and Geology <br /> Denver, CO 80222-1530 <br />Telephone 970/aW-2165 Attn: Carla Lenkev <br />Faz 970/864-2168 <br /> RE: 1st Quarter 2002 NPDES Monitoring Report <br /> New Horizon Mine Permit Number CO-000213 <br />Enclosed is the 2002 first quarter NPDES report for Sediment Containment Ponds 001, 002, 003, 004, 005, <br />006, 007, and 008. Ponds 001, 007, and 008 discharged during the monitoring period, and all water quality <br />monitoring criteria were within permit standards. As per the attached letter from CDPHE, outfalls 001 <br />through 006 were eliminated our NPDES permit, and so monitoring for these sites ceased on 1 Feb 2002. <br />WET Testing <br />The quarterly WET test of Pond 007 passed. <br />As you will recall, Pond 008 failed the ceriodaphnia portion ofthe 4`" quarter 2001 WET test. The sample <br />for that test was collected on 26 Dec. The 1" accelerated cedodaphnia test, conducted with a sample <br />collected on 2 Jan 02, failed as well. Later that same day, WFC elected to stop discharging from Pond 008 <br />and transfer the effluent to outfall 007. Fathead minnow testing did not occur during the accelerated test <br />and the discharge was transferred before a sample could be taken for the full quarterly WET test. <br />NPDES 001 required an annual WET test. I did not take one during January 2002 prior to cessation of <br />monitoring. However, the outfall still discharges and if a WET test is still required, please let me know and <br />I will pull a sample for testing. <br />I spoke with Tanya Watson conceming [he conditions conceming the NPDES 001 and 008 WET tests and <br />she suggested that I detail them in this letter and follow them up with a phone call to you when you return <br />[o work. <br />Sincerely, <br />1 <br />Tony ins <br />Mine gineer <br />cc: Harry Ranney, DMG (w/ enclosure) <br />Murari Shrestha, WFA (w(o enclosure) <br />file <br />
