Mayo and Assoclafes, LC <br />• Water qualities of spring discharges are the result of aquifer lithology and are not related to <br />mining activities. <br />Recommended Changes: <br />Spring 1 ~-2 should be eliminated from the plan because it has a very low maximum <br />discharge rate and is in the same general location as Barren Member spring 15-1. Spring G- <br />12 should be eliminated because it is redundant with G-14 and G-24, both of which are <br />decreed springs. Spring G-26B should be eliminated because it is redundant with G-26A. <br />Springs G-36, G-37, G-38, G-39, G-40, G-41, G-42, G-46, G-47, G-48 should be eliminated <br />because they are redundant with the other springs in [he Jumbo Mountain cluster. Springs <br />10-1, E10-2, E10-3, E10-4 and E15-3 should be eliminated because they are essentially <br />• seeps, are clustered closely together and they are not situated such that they can provide <br />meaningful information regarding potential impacts due to mining. Annual laboratory water <br />yuality analyses should be eliminated from several of the springs as shown on Table 2, except <br />for those parameters required by the Colorado Mined Land Reclamation Board for Coal <br />Mining regulation 2.05.6(3)(b)(iv). <br />2.2.2 Barren Member Springs <br />Discussion: <br />The current monitoring plan includes 8 Barren Member springs (Table lb). These springs <br />tend to have a wider spatial distribution than do alluvial, mantle cover, and landslide springs. <br />All of the Barren Member springs issue from groundwater systems that are shallow <br />• <br />Evaluation of the West Elk Mine Monitoring Plan <br />29 January 1999 <br />Page 10 <br />
