One of the three seeps has dried up. The other two <br />had water flows of less than one-half gallon per minute. A <br />corpc.site water ;uality sample was t?ken of .`.he seen water and sent <br />to a commercial lab for testing as per a request during the <br />OSM/CMLRD inspection on June 23, 1992. This test will determine <br />any toxic effect of the water to wildlife or livestock. <br />The surface drainage facilities were adequately maintained and were <br />working properly. No subdrain system is required by our permit, <br />since geotechnical investigation for the disposal site revealed no <br />ground water present. ?ermanent out slopes are approximately 52~ <br />complete on the toe of sub-area 2-3. These out slopes are stable. <br />A groundwater monitoring well has been installed between sub-area <br />1 and sub area 2-3. To date no wa*_er has accumulated in the wall. <br />Deserado Mine <br />P.O. Box 1067 <br />Rangely, Colorado 81648 <br />Telephone 303/671-8431 <br />Telecopier 303/671-12'_9 <br />
