r <br />2. The permanent ditch along the west side of sub-area 4 has been removed, and the <br />area seeded. (TR-39) <br />3. The embankment on sub-area 5 pond has been seeded and mulched. <br />4. Erosion control structures along in-pit ditches in sub-area 2-3 have been <br />completed. Placement of a large amount of previously stockpiled refuse has been <br />placed and compacted on sub-area 2-3 pit. The top portion of the pile, and slopes <br />have been re-contoured, and imprinted. (TR-39) <br />5. Erosion control along ditches and slope imprinting are still in progress in <br />sub-area 4. (TR-39) <br />6. Filling and compaction of cracks along sub-area 4 pond embankment using a <br />vibratory compactor was completed. <br />Sub-area 5 has not been actively worked and or compacted during this quarter. <br />No sub-drain system is required by our permit, as geotechnical investigations for the disposal site <br />revealed no ground water present. <br />Permanent out slopes remain at approximately 85% complete on the toe of sub-area 2-3 and <br />approximately 55% complete on the toe of sub-azea 4. These slopes appeared stable. Pit 5 <br />consists of a thin layer of refuse over the entire area. <br />A groundwater monitoring well had been drilled between sub-areas 1 and 2-3. To date, no water <br />has accumulated in the well. <br />To date, a total of 2,025,405 tons of refuse have been placed in sub-area Z-3, a total of 1,522,493 <br />tons of refuse have been placed on sub-area 4, and a total of 417,829 tons of refuse have been <br />placed in sub-area Sa. <br />Two compaction tests were performed on sub-azea 4 and two test were performed on sub-area <br />2-3. All areas tested exceeded the required Proctor level of 90%. <br />Both the topsoil and subsoil piles for sub-areas 2-3 and 4 have been seeded and are stable. All of <br />these seeded areas plus the area disturbed during the reclamation of sub-area 1 show vegetative <br />growth. The final discing and re-seeding of reclaimed sub-area I was completed the end of <br />September, of the cheat grass covering the azea. Re-seeding of this area was completed to try to <br />slow the growth of the weedy variety of plants and promote a more beneficial mixture of <br />vegetative growth. <br />The topsoil and sub-soil piles along with the pond and other disturbed areas associated with sub- <br />area Sa are mostly covered with vegetation. All organic material and topsoil was removed prior <br />to the storage of refuse in all areas. <br />Quarterly monitoring of RP-4 refuse pond embankment has continued, and to date appears to be <br />stable. <br />
