7.0 SPRING AND SEEP SURVEY <br />A spring and seep survey is performed annually in May, or as soon as practical after snowmelt, <br />covering the base of reclaimed areas along Trout Creek. Flow from springs or seeps that exceed <br />approximately 20 gpm are measured while flow from smaller expressions are visually estimated. <br />Additionally, a sample will be taken. annually from larger, exceeding 20 gpm, springs and seeps. <br />The complete list of parameters used for surface water monitoring sites, except for TSS, is <br />analyzed to characterize the type of flow. <br />A survey was conducted May 5, 2009 to May 6, 2009 to evaluate springs and seeps which existed <br />during past surveys at the base of the ridge along Trout Creek from the northern Moffat boundary <br />to the base of West Ridge. A total of 15 spring locations were surveyed. Of these 15 spring <br />locations, 12 were either damp or had flowing water during the 2009 survey. A total of 21 seep <br />locations were surveyed. Of these 21 seep locations, 5 were either damp or had flowing water <br />during the 2009 survey. Table 13 contains a listing of the springs and seeps observed from 1993 <br />through 2009. Spring and seep locations are shown on Plate 2. <br />Twelve of the 12 springs either damp or flowing exhibited sufficient discharge for flow to be <br />' estimated or calculated and field parameters measured during the 2009 monitoring period. Five <br />of the 5 seeps either damp or flowing also exhibited sufficient discharge for flow to be estimated <br />and field parameters measured. Several of the springs and seeps were sampled as single units <br />' due to their close proximity to each other and their apparent common origin. Flow estimates and <br />field parameters for these springs and seeps are provided in Table 14. <br />Springs SPR-1, SPR-3, SPR-5 and SPR-11 and seep 5E-23 had sufficient flow, singularly or in <br />combination with other springs or seeps, to require additional laboratory water quality sampling <br />in accordance with the mine's permit. Results of these analyses are provided in Table 15. <br />^??wWI..ENGINEERING <br />Page 18
