1995 Reclamation Bids July 7, 1991 Page 4 Task 3 Earthwork The stated objectives are regrading to establish a landform blending with surrounding topography, and the re-topsoiling of the refuse areas. Grading at both refuse areas encompasses construction of diversion and conveyance ditches across or beside the refuse disposal areas. Ditches are discussed under Task 4. Major concerns with this task center on the lack of specificity regarding location of grading work to be conducted and volumes of refuse and topsoil to be moved and/or respread. CDMG states that grading at the Sutey Pile will encompass grading a series of benches at the upper and southeastern portion of the pile. Of concern is whether CDMG proposes to regrade areas (benches) on the reclaimed face of the Sutey Pile that have had ditches previously installed and/or been topsoiled and revegetated. Lack of specificity in the bid document makes the location and extent of proposed work unclear. At the Old Refuse Pile, CDMG states that foundations (conveyor supports) may remain in place if buried to four feet. This is a common sense compromise from their former position where all foundations were to be removed. Task 4 Surface Drainages At the Sutey Pile CDMG proposes to construct ten drainage ditches; eight on or immediately adjacent to the Sutey Pile, one stream diversion above the pile, and one ditch to channel spring water to the stream diversion. There are significant concerns regarding the need to construct or reconstruct existing ditches on the Sutey Pile, the configuration of the ditches, and the ditch linings. Ditch Construction/Reconstruction Based on discussions of the current configuration of the Sutey Pile, ditches 1, 4, 5, 6, 7, and the lower portion of 8 have already been constructed. If CDMG's intention is to reconstruct these ditches, they should provide
