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 on the toe of sub-area 1 and sub- <br />area 2-3 has been started. These out slopes are stable. A <br />groundwater monitoring well has been installed between sub-area 1 <br />and sub area 2-3. To date no water has accumulated in the well. <br />We have now, to date, a total of 568,936 tons of refuse placed in <br />sub-area 1, and 930,968 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.
