3.0 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 is taken annually from larger, exceeding 20 gpm, springs and seeps. The <br />complete list of parameters used for surface water monitoring sites, except for TSS, is analyzed <br />to characterize the type of flow. <br />A survey was conducted May 11, 2010 and May 13, 2010 to evaluate springs and seeps which <br />existed during past surveys at the base of the ridge along Trout Creek from the northern Moffat <br />boundary to the base of West Ridge. A total of 15 spring locations were surveyed. Of these 15 <br />spring locations, 12 were either damp or had flowing water during the 2010 survey. A total of 20 <br />seep locations were surveyed. Of these 20 seep locations, 5 were either damp or had flowing <br />water during the 2010 survey. Table 1 contains a listing of the springs and seeps observed from <br />1993 through 2010. 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 2010 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 2. <br />Springs SPR-1, SPR-3 and SPR-11 and seep SE-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 3. <br />Pag <br />^?`YVV CENGINEE-G e 3
