Matthew S. Hayes <br />June 28, 1989 <br />Page 3 <br />The statement at the bottom of Table 1.13.A has been removed, as it <br />outdated. The affected acreage was provided previously to show the large <br />difference in the number of disturbed acres versus affected acres in the <br />permit azea. <br />2. The statement on Page 3-106 intends that the two slopes and ventilation <br />raise may be connected by two or three crosscuts in the E seam, <br />encompassing approximately 3 acres (underlying the affected acres of the <br />F seam -not in addition to) and allowing ventilation and escapeway <br />passage between them, if necessary. The possibility exists that MSHA may <br />require this type of development in the E seam. <br />3. WECC does not believe that the information requested is pertinent to the <br />application. Generally, however, the permit area encompasses all of leases <br />D-044569 and C-0117192, less than 25% of lease C-1362 and only 10% <br />or less of the Mt. Gunnison Fee lease area. <br />4. The information in the last pazagraph on page 3-32 has not changed. <br />Table 2.8.A.17 on page 2-562-54 reiterates the maximum water usage of <br />200,000 gallons per operating day (150 AF/yr.) and provides the current <br />usage estimate of 15 AF per year. <br />"[[I Hydrologic Balance" <br />1. The Rollins Sandstone is a marginal aquifer in terms of yield and water <br />quality and, to our knowledge, has no points of usage in the mine vicinity. <br />Well R-1, drilled by WECC in 1976, appeazs to be the only well completed <br />in the Rollins Sandstone in the mine vicinity. Figvre 1 shows [he location <br />of Mesaverde wells in the region compiled in a 1986 U.S. Geological <br />Survey report (Brooks and Ackerman, 1986). Two wells (designated 17 <br />and 76) within 3 miles of R-1 aze completed in the Mesaverde; however, <br />one or possibly both of these wells are probably completed above the <br />Rollins Sandstone. Water levels for these wells indicate a gradient <br />paralleling the North Fork River. Locally, it is expected that ground water <br />converges in the Rollins beneath the North Fork and moves down-river <br />through fractures beneath the North Fork. <br />
