be created during topsoil application in order to help disperse runoff and to promote revegetation <br />potential. Transverse benches may be excavated to minimize erosion potential by limiting the <br />overall slope distance. Fertilizer application, seeding, mulching and planting of trees and shrubs <br />will complete this approximately five acre project. <br />Project Area East of Road A and West of the Dutch Creek Flume <br />The largest project to be accomplished in this area is the replacement of the Dutch Creek Flume <br />with a naturally functioning stream channel. Mining operations diverted Dutch Creek to the <br />south and east of the facilities area in order to maximize work areas. The creek was diverted into <br />a 300 feet long concrete flume twelve feet in width and four feet tall. Dutch Creek cascades forty <br />feet to its confluence with Coal Creek neaz the north end of the flume. The end of the flume at <br />its junction with the forty feet tall end wall supporting it appears to be structurally unsound. <br />Further, slope failures, particularly on the east side of the flume, may endanger the base of the <br />flume further upstream. In order to alleviate concerns about the failure of the flume, a naturally <br />functioning stream channel has been designed to eliminate the need for the flume. This stream <br />channel is being constructed within the alluvial fan created by Dutch Creek prior to its being <br />channelized into the flume. <br />The new Dutch Creek Diversion channel is approximately 1,200 feet in length. It varies in width <br />between forty and eighty feet, and averages about twenty feet in depth. The diversion will <br />effectively isolate the western portion of the 001 pond contributing area from the pond system. <br />To accomplish the design parameters, approximately 27,000 cubic yards of material will be <br />excavated from the channel footprint, and placed as fill, primazily to the east of the channel. The <br />channel will be heavily rip rapped with naturally occurring materials. The materials to be <br />excavated and used as fill are alluvial in nature, and are composed almost exclusively of slightly <br />metamorphosed particles of Mancos Shale and Mesaverde Group sandstones and shales. Particle <br />sizes vary from silt and clay to boulder, with cobble sized materials being dominant. <br />Other activities to be accomplished in this area include the temporary stockpiling of topsoil east <br />of the new diversion for later use in other areas. Eventually, the flume will be filled in with <br />earthen materials, and the entire area between the Diversion and the Old Refuse Pile will be <br />graded into a hummocky topography. Topsoil will be applied over this approximately three acre <br />area, and revegetation will occur. <br />West of Road A Project Area <br />The primary activity to be accomplished in this area is the placement of approximately 50,000 <br />cubic yazds of coal refuse excavated from the north facing slope of the Old Refuse Pile during <br />completion of the Huntsman Project. This refuse has been placed on top of approximately <br />30,000 cubic yards of demolished concrete at the base of the north facing hill immediately south <br />of the former location of the wash plant. <br />The coal refuse has been placed in horizontal lifts approximately two feet thick each, and <br />
