Moro and Assoelafea, LC <br />measurement is necessary because the operator may at some time in the future have to verify <br />that possible discharge rate changes are due to either seasonal or short-term climatic factors. <br />There has been no historical evidence that coal mining has affected the water chemistry of <br />springs. Except for shallow groundwater systems, which may be impacted by the refuse pile, <br />the potential for coal mining to affect the chemical character of spring discharges is <br />extremely low. <br />Each of the groups of springs and recommendations are described below <br />2.2.1 Alluvial, Mautle Cover, and Landslide Springs <br />Discrrsstore: <br />The current monitoring plan includes one alluvial spring, 4 mantle cover springs, 17 Barren <br />Member landslide springs, 6 Upper Member landslide springs, one Lower Member landslide <br />spring, and one Rollins Sandstone landslide spring (Table lb). All of these springs issue <br />from groundwater systems that are shallowly circulating and that are dependent on seasonal <br />recharge. Almost all of these springs periodically go dry. Because most of these springs are <br />located in a fairly tight cluster on Jumbo Mountain, which is no longer an active mining area, <br />and along Sylvester Gulch, there is considerable redundancy in the locations of monitored <br />springs. A few other springs are located in more spatially distant areas. <br /> <br />Evaluation of [he West Elk Mine Monitoring Plan <br />29 January 1999 <br />Page 9 <br />
