EXHIBIT D Mining Plan Mining Limits IHC Scott proposes to mine in the land located in the parcel of land situated in the northeast 1/4 of Section 24, Township 4 North, Range 67 West of the 6th Principal Meridian, in Weld County, Colorado. The proposed mining site is located within the Town of Milliken. CR 46 is north of the property and an access road from the property connects to CR 46 near the intersection of CR 46 and CR 25. The South Platte River is adjacent to the property and approximately 880 feet south of the site on the south side of the permit boundary and 140 feet from the east side of the permit boundary. The dominant land use surrounding the property is agricultural use and industrial use. An aggregate processing plant will be located in Phase 1. These areas will contain stockpiles, portable equipment, storage bins, and silos as necessary to support the plant operations. Mining will start from the northeast corner of the mining limit then moving south approximately to one third of the property then west,then moving south to another third of the property back to the east, then moving south to the final third of the property to the west to complete mining and reclamation. All local, State, and Federal rules and regulations will be followed for the storage and handling of any petroleum products. The permit boundary will encompass approximately 111.01 acres which will all be affected acreage, and approximately 98.24 acres being mined. The remaining area will consist of access roads and disturbed land. The following table depicts the different affected acreage: Affected Acreage Mining Plan Area acres Mined Area 98.24 Access Roads 2.36 Disturbed Land 10.41 TOTAL 111.01 Various setbacks from adjacent roads, adjacent structures, and oil and gas infrastructure will be maintained as mining occurs. The final executed agreements are expected to be obtained in the near future and will be forwarded to the Division when they are available. A minimum 200-foot setback from any existing oil/gas facility will be maintained until that time. See Exhibit C, Mining Plan Map, and the Slope Stability Report for the mining limit configuration and information on setbacks and their locations. The abandoned wells would be cutoff after mining has reached the bedrock surface or the reclaimed slope surface where a new cap and any additional concrete for the existing plug would be needed. Petroleum Development Corporation (PDC) is the leaseholder and operator of the existing abandoned wells. Discussions with PDC have indicated they would cut down the existing casings as mining occurs. We have also worked with McCarty Engineering, LLC to provide this service at other mining permit locations for other operators. If PDC does not want to perform this work then McCarty Engineering, LLC would be contacted to do it. They are IHC Scott,Inc. J&T Consulting,Inc.
