EXHIBIT D Mining Plan Mining Limits Ogilvy River Farm, LLC proposes to mine in the land located in the Southeast % of the Southeast 1/4 of Section 5, Township 5 North, Range 64 West of the 6th Principal Meridian and the Northeast 1/4 of the Northeast ' of Section 8, Township 5 North, Range 64 West of the 6th Principal Meridian, in Weld County, Colorado. The proposed mining site is located approximately 1,500 feet south of WCR 60%, is adjacent to WCR 53 on the side, and is adjacent to the South Platte River on the south side of the site. WCR 53 is immediately adjacent to the east side of the permit boundary and the South Platte River is immediately adjacent to the south side of the permit boundary. Access to the site will be located at the east side of the permit boundary off of WCR 53. The dominant land use surrounding the property is agricultural and industrial. The permit boundary will encompass approximately 71.91 acres which will all be affected acreage, and approximately 45.06 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 45.06 Access Roads 2.34 Disturbed Land 24.51 TOTAL 71.91 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. If PDC does not want to perform this work then McCarty Engineering, LLC would be contacted to do it. They are licensed and bonded to obtain approvals from the COGCC to do these types of re-plug services on abandoned oil and gas wells. EMI Ogilvy River Farm,LLC J&T Consulting,Inc.
