Vest Elk Mine <br />Due to low permeabilities within the Rollins Sandstone and the B Seam, local groundwater flow is <br />controlled by secondary porosity (i.e., fractures). However, there is a general regional trend within <br />these formations for the groundwater to flow in the direction of the northeast dip. <br />No private, commercial, or industrial water supply wells other than those owned by MCC are <br />presently located within the pernnit area based on a February 2003 review of the Colorado State <br />Engineer's Office (SEO) well permit database. A summary of the permitted wells within the permit <br />area are provided in Table 3A. This table summarizes the well location, pen-nit number, owner's <br />name, reported well yield and permitted use for each of the wells listed. Of the 29 permitted wells <br />within the West Elk Mine permit boundary, 22 are permitted to MCC or its mining company <br />predecessors. The remaining seven wells are permitted to private individuals. Of these seven <br />permits, three have expired. Each of the remaining four wells is now under the ownership of MCC <br />and is no longer in use. Reported well yields are generally low (less than 2 gpm with one <br />monitoring well reporting 4 gpm) throughout the area except in alluvial wells located along the <br />North Fork in Sections 9, 10 and 11 where reported yields range from 9.7 to 30 gpm. <br />Table 3A <br />t'1 <br />Permitted Well Summary <br />West Elk Mine Permit Boundarv Area.
