EXHIBIT D <br /> Mining Plan <br /> Mining Limits <br /> J-2 Contracting proposes to mine in the land located in the north 1/2 of section 12, and the <br /> southeast % of northeast corner of section 11, township 5 north, range 65 west of the 6th p.m., <br /> and the south 1/2 section of section 1, township 6 north, range 65 west of the 6th p.m., Weld <br /> County, Colorado. The proposed mining site is located approximately 2 miles north and 2 miles <br /> west of the Town of Kersey, and approximately 2 miles north of State Highway 34. The South <br /> Platte River is approximately 600 feet south of the site on the west side of the permit boundary <br /> and 200 feet south and east of the site on the east side of the permit boundary. The Cache La <br /> Poudre River is adjacent to the north side of the permit boundary. The Weld County Parkway is <br /> immediately adjacent to the west side of the permit boundary. Access to the site will be located <br /> at the southwest corner of the permit boundary off of the Weld County Parkway. The dominant <br /> land use surrounding the property is agricultural. <br /> An aggregate processing plant area and a concrete and asphalt batch plant area will be located <br /> within the mining area as shown on the Mining Plan Map. These areas will contain stockpiles, <br /> portable equipment, storage bins, and silos as necessary to support the plant operations. <br /> Designated locations for concrete truck washout and excess concrete product dumping will be <br /> provided to ensure that waste materials are recycled and kept from entering the stormwater <br /> flows on the site. <br /> The concrete truck washout area will be a 30 foot by 20 foot three cell concrete structure. <br /> Concrete trucks will wash the residual product from their mixing drums and chutes into the first <br /> cell of the structure. The first cell spills into the second cell, which spills into the third cell. This <br /> allows the aggregate and suspended fines to settle into the cells over time. The water and <br /> settled material in the three cells is then removed as required and recycled into the concrete <br /> batch plant. Generally, the cells are cleaned on a weekly schedule. <br /> The excess product dumping area will be approximately 50 feet by 100 feet and have an <br /> exterior berm to limit the migration of stormwater flows to and from the surrounding areas. <br /> Excess product that is deposited in this area will be allowed to cure for approximately 90 days <br /> until it becomes inert. It will then be crushed and recycled. <br /> All local, State, and Federal rules and regulations will be followed for the storage and handling <br /> of any fuel, asphalt, cement, flyash, and admixtures required for the batching facilities. <br /> The permit boundary will encompass approximately 227.52 acres which will all be affected <br /> acreage, and approximately 187.66 acres being mined. The remaining area will consist of <br /> access roads and disturbed land.
