APPENDIX B <br />SPRING AND SEEP SURVEY <br />Basin initiated a monitoring program of the springs and seeps within a one mile radius of the Golden Eagle <br />Mine workings, following the preliminary spring and seep survey conducted in February 1984 using aerial <br />photographs and field verification and sampling in May 1984. Four (sites 15, 16, 17, and 20) fell within this <br />circumscribed region and were verified. Following review of the 84-85 data, the frequency of monitoring <br />springs and seeps was decreased to once per growing season during the month ofAugust. This report presents <br />the results ofthe baseline monitoring through 2002 at these four locations. Nine additional springs and seeps <br />were added in 1988, as part of the permit expansion. They included springs and seeps in Cherry, Alamosito, <br />Lopez, Wet, Pratt and Sawmill Canyons. <br />The 2002 spring and seep survey was completed between August 22 and September 6, 2002. The 2002 water <br />year was drier than average. Flows were consistent with those recorded previously. The expression of most <br />sites was limited to seep or wet depressions. The highest flows were observed at springs 18 (Parras Creek) and <br />20 (Santistevan Canyon). <br />Methods <br />During the monitoring period each location was visited. Flow of each spring and seep was measured. Water <br />quality measurements of pH, conductivity and temperature were made. <br />Results <br />The locations of all springs and seeps are presented in the permit document, Maps 7A and 7B, Regional <br />Hydrology. <br />Data collected to date for each location monitored is presented in Tables B-1 through B-14 (all tables are <br />consolidated at the end ofthis Appendix). <br />Siring #1 -Cherry Canvon (Table B-1). This seep originates from the interface of coal and shale and <br />monitoring was initiated in 1988. The spring has been dry 50 percent of the time observed, including 2002. It <br />is a saline and alkaline site. <br />Snrine #2-7 -Alamosito Canvon (Table B-2). Monitoring at this series of springs and seeps began in 1988 <br />and covers a reach of the canyon. Each specific spring or seep can not be distinguished. The seepage results <br />from an interface between the coal and shale. Flows have been variable (as high as 40 gpm) but are usually <br />low; there was no flow in 2002. It is a saline and alkaline site. <br />Sprin¢ # 15 -Cimela Canvon (Table B-3). Spring # 15 is a minor azea of seepage from the interface of shale <br />and sandstone below a coal seam outcrop. Typically dry or a seep, since monitoring was initiated in 1984, flow <br />was up to 3 gpm in 1993. The spring was dry in 2002. This spring is not significant to surface flow and only <br />has value for livestock and wildlife watering in the spring of the year. <br />Sorine # 16 -Cimela Canvon (Table B-4). Flow originates from the interface of shale and sandstone and has <br />ranged from dry to 3 gpm since monitoring began in 1984. The spring was dry in 2002. On all occasions flow <br />was absorbed into the al luvium within 100 yards of the source and does not appeaz to contribute significantly <br />to surface flow. Water quality measured during the 1989 survey was the result of surface water runoff flow <br />which is indicated by the different quality measurements. The spring does provide livestock and wildlife <br />water, however, it is not that important due to the location of a stock pond 200 yards upstream. <br />B-1 <br />
