III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspection. Comments also describe any enforcement actions taken during the inspection <br />and the facts or evidence supporting the enforcement action. <br />various reclaimed areas were in general stable and functional. Minor maintenance is <br />warranted at the upper end of the rock lined channel at the upper end of the CBA-2 soil <br />borrow area, where the fabric liner was undercut. The scoured area will need to be filled in, <br />-the upper end of the liner re-buried and rock replaced. <br />Erosion is minimal on reclaimed areas due to adequate vegetation cover, proper drainage <br />diversion, and/or extensive soil roughness. One erosional rill was observed on the lower <br />slope of the North Portal reclaimed area, approximately 60 yards north of the silt fence. <br />The rill is less than 9" deep at this time, but stabilization of the head of the rill with packed <br />loose straw similar measures might prevent further cutting. <br />Or~ <br />Backfill and Grading <br />Backfilled areas inspected included the North Portal Facility Area, three soil borrow areas, 2- <br />West Portals and South Fan, "B" Substation Site, the North Decline, and the conveyor <br />corridor between the power plant access road crossing and the rail loop. No indicators of <br />instability or other backfill and grading compliance problems were observed. <br />Processing Waste <br />The CRDA-1, CRDA-2, and RSRDA refuse piles were inspected and no problems were <br />observed. Diversion and perimeter ditches and terrace drains were properly maintained and <br />functional. The rill adjacent to the steep "B" segment of the RSRDA upper diversion ditch <br />noted in the October inspection report had been properly stabilized. <br />Suooort Facilities <br />Major, highly visible aspects of the suspended conveyor reclamation project were completed <br />during the week. By 5pm Thursday, the suspended sections of the 9' diameter conveyor <br />tube over the Colorado River and associated cables had been removed, and the steel <br />support tower structures on both sides of the river had been taken down. Three large <br />cranes were used in the project. Individual tube sections that had been separated by <br />workers in suspended baskets were lifted out by crane, and loaded onto a large flatbed <br />trailer. Some concrete foundation demolition work remains to be done, along with removal <br />of the non-suspended conveyor tube section on the south bank of the river, and backfilling <br />of a minimum 100' segment of the buried section of the tube. <br />Clean fill material to construct a ramp across a side channel on the north side of the river <br />(approved in the Corps of Engineers Permit for crane access) had been obtained from the <br />loadout bench at the UTL. This material will be used to backfill the buried section of <br />conveyor tube. Following completion of the demolition project, the surface disturbance <br />areas will be final graded, topsoiled, and seeded, including the remaining segment of <br />overland conveyor corridor between former Transfer #2 and the power plant access road,Me <br />2 <br />
