The ponds were present prior to any <br />permitting of this site and 7.5' Quadrangle Maps produced by the U.S. Geological Survey in <br />1978 clearly show that the ponds were pre- existing before the SEO requirements began. The <br />pre -81 water is the only water exposed on the site currently. When the ready mix plant is <br />removed and we begin preparing the site for mining, we will put a temporary substitute <br />supply plan back in place to account for dewatering, dust control etc. An aerial photo from <br />the USGS.gov website is attached with photography from 1980. <br />2) The mine identification sign and affected area boundary markers were not observed. <br />Mine sign and stakes were all present during the inspection. Pictures are attached and <br />documented for boundary markers. <br />Should you have any additional questions, please give me a call at (970)227 -4041. <br />Sincerely, <br />Julie Mikulas <br />Land Manager <br />RECEIVED <br />JUL 0 2 2012 <br />.jiviawn C :;UJaIriation, <br />Mining & Safety <br />
