-, <br /> <br />The only present uses on the property are range land for cattle on the portions of the property west <br />of the S. Platte River, and an area of the plant site presently used for mobile home storage. No <br />structures exist on any of the property except for fencing and isolated farm structures on the portions Z <br />of the property west of the River. There are extensive tree stands along the River and on portions of ' <br />arcel A. A Division of Wddlife (DOW) questionnaire was completed, and no endangered or critical <br />wildlife habitat was identified. Surveys for the Ute Ladies tresses orchid and the Prebles meadow <br />jumping mouse were also conducted, and neither were found to be present. It is expected that <br />jurisdictional wetlands on portions ofParcel B, Parcel C, and perhaps Parcel A will be identified, and <br />a permit from the Army Corp of Engineers to create replacement wetlands will be necessary to (Np <br />remove all or portions of any identified wetland areas. A wetland delineation is being prepared by <br />another consultant, who we anticipate will also process the necessary permit to remove any existing <br />wetlands and provide for wetland's replacement. <br />All of the property east and most of the property west of the S. Platte River are within the 100 year <br />floodplain of the River. No mining shall occur within 400' of the low flow channel of the S. Platte <br />River without approval of the Urban Drainage and Flood Control District (LTD&FCD), and all <br />activities within the 100 year floodplain of the S. Platte River shall require a Flood Plain Use Permit <br />from Adams County. Any stockpiles of topsoil and overburden in the floodplain, and particularly in <br />the floodway area, will be placed in accordance with approvals of the UD&FCD and the Floodplain <br />Use Pemvt. General proposed standards for the placement of stockpiles in any floodplain area have r,~„i <br />been included in Exhibit G. A conveyor will also be constructed across the S. Platte River from the <br /> <br />west portion of the property (D pazcels) to the plant site (C parcels), and UD&FCD approval and a 5~ <br />Floodplain Use permit from Adams County for the conveyor's support structures in the S. Platte <br />River floodplain area will also be obtained. ~~~ ~ J~~ <br />a <br />The site contains approximately 2-5+ feet of topsoil and overburden overlying 20-30+ feet of T5 0~ <br />alluvium sand and gravel material underlain by clay shale and/or claystone bedrock, which acts as a ~. <br />natural barrier between the alluvium aquifer and the deeper bedrock aquifers. A slurry wall will be <br />installed around the perimeter of the D parcels to limit groundwater infiltration for dry mining and <br />f <br />l i <br />~ <br />a <br />uture sea <br />ed storage water facility for reclamation. Mining east of the S. Platte River (Parcel B and (j <br />`~~ <br /> <br />parts ofParcel A) will be wet mined for afteruse as open space wetlands/wildlife area. Where any G <br />" <br />~,, <br />I~f <br />groundwater would be permanently exposed, after 3 years an application to water court will be made <br />for permanent approval of the substitute water supply plan. Dedication of a trail condor and other <br />undisturbed property along both sides of the S. Platte River may be conveyed to the Adams County <br />and other appropriate public and/or non-profit agencies for trail construction and maintenance as <br />natural open space prior to completing mining and reclamation. <br />~ ~.q-~ <br />~~] <br />~`~ <br />2 <br />
