Page Z Soils? Sand to Fine Loamy Sand-dominant soil types include:Vona Loamy Sand, Loup-Boel Loamy Sands,Valent Sand,Bresser Sandy Loam Climate? Mean annual air temperature:48 to 55 degrees Fahrenheit Mean Annual precipitation: 13 to 15 inches Frost-free period:130 to 160 days Water Resources: Stormwater Retention Pond is located in the southeast corner of the parcel, approximately 240 feet from the proposed disturbance area.Evan's Number 2 Ditch is located south of the parcel,approximately 650 feet from the proposed disturbance area.Platte Valley Ditch is located south of the parcel approximately 1,500 feet from the proposed disturbance area.Both irrigation ditches are fed from the South Platte River and flow into Milton Reservoir. Wildlife: No critical wildlife habitat or wildlife species will be impacted by the proposed operation. PROJECT DESCRIPTION Korwell is proposing to mine the upper 50 to 80 percent of topsoil from 132 acres of existing agricultural land in order to provide topsoil for reclamation of third-party development sites.The topsoil on Site has been measured between 14-18 inches in depth.The operator will extract approximately 12-14 inches of topsoil,leaving at least 3-6 inches on Site for reclamation purposes.The goal to remove a total of 372,679 tons of topsoil will occur in four phases over the course of four to six years after obtaining the Construction Material Regular 112 Operation Permit. RECLAMATION METHODS Mining and reclamation will occur in four phases based on field quadrant: - Phase I(northeast quadrant) - Phase II(northwest quadrant) - Phase III (southeast quadrant) - Phase IV(southwest quadrant) Within the first year following permit approval, the operator will mine topsoil from the northeast quadrant of the site; followed by reclamation efforts. Mining and subsequent reclamation of the southeast, northwest, and southwest quadrants will occur in years 2, 3, and potentially 4 and 5,respectively.Each quadrant, not including the"dry corners,"is approximately 33 acres. Topsoil is to be mined for immediate sale.Stockpiling and stabilization of topsoil will not be required; the extracted topsoil will be removed from the site and sold to a third-party.During this process,the topsoil will be handled as little as possible to maintain soil health and fertility. STAGING A staging area has been designated in the northwest quadrant of the site. The staging area is approximately 6-8 acres and will provide room for equipment storage, mined topsoil, and truck loading operations. Additionally, the staging area will include an access point for ingress and egress traffic to
