A small portion of oak brush, approximately <br />0.02 acre or 850 square feet, will be cleared and placed in the Delta County Landfill. The topsoil <br />will then be salvaged from the foundation area. The quantity of topsoil material is estimated to be <br />50.0 cubic yards, assuming a 20-inch depth. The small amount of topsoil, approximately five <br />highway dump truck loads, will be placed on the topsoil pile located on the Lower Refuse Pile. <br />The material to be placed at the foundation wall is estimated to be 142 cubic yards of 12-inch <br />plus, D50 sized riprap material. Access to the area will be gained from the lower access road on <br />the existing roller compacted concrete buttress. The source of the riprap material is from the <br />material stacked along the east side of the Lower Refuse Pile. The buttress material will lend <br />additional support to the existing Screening Plant foundation wall. <br />Please don't hesitate to contact me should you have questions. <br />Si ly, <br />~. i~~ <br />my A. arbe <br />Environmental Coordinator <br />Enclosure <br />xc: Norm Every <br />Phil Schmidt <br />Kathy Welt <br />MRNO 116D <br />
