• EXHIBIT D Mining Plan Mining Limits Central Colorado Water Conservancy District (CCWCD) proposes to mine the land located in the Northeast 1/4 of Section 30, Township 4 North, Range 66 West of the 6th Principal Meridian, in Weld County, Colorado. The proposed mining site is located adjacent to WCR 42 on the north side, WCR 25.5 on the west side, and CO Hwy 60 on the east side. WCR 40 is approximately 2,630 feet to the south of the permit boundary. Access to the site will be located on the south side of the permit boundary and approximately 1,311 feet west of CO Hwy 60 and 1,285 feet east of WCR 25.5. The dominant land use surrounding the property is agricultural. The permit boundary will encompass approximately 147.83 acres which will all be affected acreage, and approximately 72.53 acres being mined. The remaining area will consist of access roads and disturbed land (processing areas, stockpiles, etc.). The following table depicts the different affected acreage: Affected Acreage Mining Plan Area (acres) Mined Area (North Cell) 32.42 Mined Area (South Cell) 40.11 Access Roads (North Cell) 2.11 Access Roads (South Cell) 2.43 Western Mutual Ditch 2.62 Existing Gravel Roads and Structures 6.22 i Disturbed Land 61.92 TOTAL 147.83 Various setbacks from adjacent roads, adjacent structures, and oil and gas infrastructure will be maintained as mining occurs. All setbacks specified in the surface use agreements with the oil/gas companies will be followed. 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.
