were made during the summer and fall of 1983. Typically, quality and quantity <br />varied from spring to spring. <br />In general, the water was very hard, with average TD values ranging from 458 mg/1 <br />to 2,150 mg/1. Sulfate was generally more dominant than bicarbonate. All but two <br />springs experienced a decline in flow during the course of the summer. Five had <br />dried up by late August, three others flowed less water during base flow and two <br />were flowing at about the same rate in October as in June. <br />Three springs, Olson Spring (5-45 on Dry Creek), S-5 (on an 006 Gulch tributary), <br />and 5-41 (in the 006 Gulch channel), were projected to be impacted by mining within <br />the original permit area. 5-41, which fed a registered stock pond (Temple Pond No. <br />2) was mined through and was buried in spoils in 1998. Pond 006 will replace the <br />Temple Pond No. 2 as a stock water impoundment. S-5 has been observed to flow <br />on only three occasions: in the spring of 1983, 1997 and 1998. Olson Spring has an <br />adjudicated domestic water right. Conductivity of the Olson Spring has displayed a <br />decreasing trend. <br />Two additional native springs occur along Hubberson Gulch upstream from the <br />potential influence of mining in the original permit area, but downstream from <br />mining activity in the south extension area. 5-49 was located in the 016 Gulch <br />directly above the Pond 016 Site. The spring was developed with a 4 inch PVC pipe <br />that flowed into a metal stock tank. It was sampled between August 1997 and August <br />2001, when it was abandoned and subsequently mined through. S-7 serves as the <br />non -potable water supply for the Smith Ranch on Hubberson Gulch in Section 21. <br />Sampling was discontinued in 1990 but reinitiated in 1999, due to its location <br />downstream from south extension area mining. Monitoring was conducted between <br />1999 and 2005, when discontinuance of monitoring was approved in TR -52. TDS <br />values peaked in 1997, and decreased in subsequent years. <br />A discussion of projected impacts can be found in Section III G. <br />SCC performs a spoil spring survey following snowmelt each year, with locations of <br />springs of greater than 5 GPM added to the monitoring program, and with spring <br />location and monitoring data to be included in subsequent Annual Hydrology <br />Reports. One full -suite sample and field parameters samples are collected each year. <br />Surface Water <br />The applicant will conduct monitoring of surface water in a manner approved by the <br />Division. The monitoring plan was submitted under 2.05.6(3)(b)(iv) and can be <br />found in Appendix 15-3A of the permit application package. A number of <br />amendments to the surface water parameter list and analytical techniques for certain <br />parameters were approved in TR -69, in 2010. <br />17 <br />
