<br /> <br />highwall. Drilling of the three suggested strat holes are <br />believed to be unnecessary in addition to being very costly and <br />time consuming for the limited expansion of the data base. <br />Response B <br />Since the flow is both seasonal and storm event related, <br />then sampling can only occur under these two specific conditions. <br />Additional baseline water quality data can easily be established <br />as this permitting process continues. <br />Response C <br />Required monitoring procedures away from the mine area on <br />Lightner Creek and Coal Gulch should be adequate enough to detect <br />any changes in water quality. One alluvium well data point <br />located on Coal Gulch adjacent to Cherry Creek, on the north side <br />of Hiway 160, would allow sufficient alluvial monitoring. This <br />well would allow detection of any excursion near its departure <br />point from the permit area. <br />Response D <br />The Menefee formation is generally not considered to be an <br />aquifer. In the case of the Fiederspiel-Yeager well, it is <br />situated on the opposite flank of the Perins Peak syncline; and <br />over 3/4 mile to the south of the mine area. The well bottom <br />depth of 7342 feet in elevation; over 250' above the portal <br />elevation. It is assumed to be wholly in the Cliff House <br />sandstone, as is the Messier well. <br />
