Ditch is of sufficient quality for drinking water, agricultural use and livestock drinking water. This water <br />originates from the San Miguel River upstream of Naturita, and is currently the primary source of water in <br />the vicinity for the previously mentioned uses. Surface water in Calamity and Tuttle Draws, as well as the <br />monitored tributaries, is not suitable for use as a source of drinking water. New Horizon has knowledge of <br />irrigation being conducted using water from Calamity (Mr. Mel Statts, south of New Horizon Permit <br />Boundary and bordering Calamity Draw). However, all surface water monitored at sites established in the <br />New Horizon 2 area fall into suitability criteria for livestock drinking water and irrigation. Livestock and <br />wildlife commonly use Calamity and Tuttle Draws as sources of drinking water. As long as the Colorado <br />Co-operative Company continues to operate the ditch system, there will remain a sufficient supply of water <br />well suited for domestic (drinking), agricultural and livestock use. <br />Hydrological Monitoring Program <br />New Horizon will report discharges associated with its CDPS permit (sediment pond discharges) in <br />accordance with the Clean Water Act of 1977 on a quarterly basis to the Colorado Department of Public <br />Health and Environment. Surface water and groundwater monitoring data (monitoring locations listed <br />in the tables below) is reported to the Division in an annual hydrology report. Annual hydrologic <br />reports for the period of October through September of the following year will be submitted to the <br />Division by December 31 of each year. <br />New Horizon monitors the following sites: <br />Sedimentation Ponds — Discharges associated with the sediment ponds will be monitored as required under <br />New Horizon's CDPS Permit which is issued by the Colorado Department of Public Health and <br />Environment. New Horizon will measure the quantity and quality of discharges from the permit area in <br />compliance with the CDPS permit requirements. A copy of New Horizon's CDPS permit is available <br />onsite for review as necessary. <br />Surface Water - Six surface water sites will be monitored for the New Horizon mine. These sites <br />include locations along Calamity Draw, Tuttle Draw, and the West Lateral Ditch. <br />Monitoring Monitoring Monitoring Ouarterly Field Ouarterly Laboratory <br />Type Location Frequency Parameters Parameters <br />Surface <br />SW -N102' <br />Quarterly <br />See List Below <br />See List Below. <br />Water <br />Surface <br />SW -N1032 <br />Quarterly <br />See List Below. <br />See List Below. <br />Water <br />Surface <br />SW -N1043 <br />Quarterly <br />See List Below. <br />See List Below. <br />Water <br />Surface <br />SW -N1084 <br />Quarterly <br />See List Below <br />See List Below. <br />Water <br />Surface <br />SW -N15 <br />Quarterly <br />See List Below <br />See List Below. <br />Water <br />Surface <br />SW -N36 <br />Quarterly <br />See List Below <br />See List Below. <br />Water <br />1.
