I <br />• <br /> <br />Ezenafv[ Sum/wry <br />dropped 22' during the water year. This <br />site is located neaz the main facilities azea. <br />Activities at the Lower Refuse Pile had an <br />insignificant effect on surface or <br />groundwater quality outside the permit area. <br />Persistent (from 1994) no or low flows <br />suggest underground mining activities may <br />have diminished flows in the G-26B spring. <br />This site overlies the F-Seam in the Lone <br />Pine azea and lies above B-seam training. <br />Underground mining did not produce any <br />new significant effects on springs or surface <br />water monitoring stations during water year <br />1995. Above average precipitation <br />increased spring flows and extended the <br />period of flows for intetmivent springs and <br />streams. <br />Monitoring data for the period 1 October <br />1994 through 30 September 1995 show no <br />significant adverse impacts to the hydrologic <br />balance from mining activities at the West <br />Elk Mine. Water Yeaz 1996 is expected to <br />be similaz to 1995 relative to hydrology at <br />the mine. No significant impacts are <br />expected. <br />AWt-9!.310/OS/i3/96(I~78pm) <br />2 REVLSED 0927/96 <br />
