San Miguel River. Because the listed parameters (physical and biological, only) are not applicable <br />to both Tuttle and Calamity Draws, the nearest segment (downstream) in which applicable <br />standards have been promulgated (Segment 5) are used to compare surface water quality of <br />Calamity (SW-N103) and Tuttle Draws (SW-N3, NPDES 001 and NPDES 006). <br />Exceedences were observed at three sites: 1) iron at San Miguel #1 (downstream of Turtle Draw); <br />2) zinc and manganese at SW-N103; and 3) nickel at NPDES 006. <br />Based on the rigorous comparisons made, it is evident that water delivered by the West Lateral <br />Irrigation Ditch is of sufficient quality for drinking water, agricultural use and livestock drinking <br />water. This water originates from the San Miguel River upstream of Naturita, and is currently the <br />primary source of water in the vicinity for the previously mentioned uses., Surface water in Calamity <br />and Tuttle Draws, as well as the monitored tributaries, is not suitable for use as a source of drinking <br />water. WFC has knowledge of irrigation being conducted using water from Calamity (Mr. Mel <br />Stotts, south of W FC Permit Boundary and bordering Calamity Draw). However, all surface water <br />monitored at sites established in the New Horizon 2 area fall into suitability criteria for livestock <br />drinking water and irrigation. Livestock and wildlife commonly use Calamity and Tuttle Draws as <br />sources of drinking water. As long as the Colorado Co-operative Company continues to operate <br />the ditch system, there will remain a sufficient supply of water well suited for domestic (drinking), <br />agricultural and livestock use. <br />EFFECTS OF MR-52 ON THE HYDROLOGICAL MONITORING PROGRAM <br />Pursuant to the successful application for bond release on much of the New Horizon I mine area, <br />effective November 2001, the following water monitoring sites were abandoned: <br />Groundwater (GW) <br />GW-N1 (4"diawell) GW-N10 GW-N11 <br />GW-N24 GW-N25 GW-N26 <br />GW-N28 GW-N4 GW-N4R <br />Surface Water (SW) <br />Spoil Spring #1 Spoil Spring #3 <br />NPDES 002 <br />NPDES 004 <br />NPDES 006 <br />NPDES 003 <br />NDPES 005 <br />NPDES 001 <br />The monitoring wells abandoned were closed as per state regulations. Monitoring wells GW-N3, <br />GW-N8, GW-N9 and GW-N27 will be left open, but not monitored until required by the State at <br />(Revised 25 Jul 2002) 2.04.7-38 <br />
