The surface drainage facilities <br />were adequately maintained and were working properly. No subdrain <br />system is required by our permit, since geotechnical investigation <br />for the disposal site revealed no ground water present. Permanent <br />out slopes are being constructed now on the toe of sub-area 1 and <br />are stable. A groundwater monitoring well has been installed <br />between sub-area 1 and sub area 2-3. To date no water has <br />accumulated in the well. <br />we have now, to date, a total of 567,515 tons of refuse placed in <br />sub-area 1, and 783,187 tons placed in sub-area 2-3. <br />Both the topsoil and subsoil piles for those areas have been seeded <br />and are stable. Removal and stock piling of all organic material <br />and topsoil prior to disposal of refuse has been completed. <br />Deserado Aline <br />P.O. Noz 1067 <br />Rangely.
