Banks and Gesso LLC <br /> Exhibit D — Mining Plan <br /> Maryland Creek Ranch has a significant deposit of sand and gravel located in the alluvium of <br /> the Blue River in Summit County. The western side of the river valley is bisected by State <br /> Highway 9; the Maryland Creek Ranch deposit lies on the west side of the highway. <br /> The sand and gravel deposit is 45 to 50 feet deep and in some places the deposit is deeper. <br /> The overburden and topsoil vary in thickness from three to ten feet. Bedrock under the mineral <br /> deposit is medium hard to hard shale. <br /> Sand and gravel is the primary product produced. Excess topsoil and overburden may be sold <br /> as a secondary material. The intended principal use of mine deposits is construction <br /> aggregates. These materials will be sold to customers and utilized in the on-site asphalt and <br /> concrete production plants. <br /> The deposit will be mined wet through the use of a dragline and front-end loader. Initially the <br /> topsoil and overburden will be stripped by scrapers and dozers. This material will be deposited <br /> separately in stockpiles adjacent to the mining operation. Later it will be used in reclaiming and <br /> sloping the lakeshore. With concurrent reclamation, it is the intent of the operator to replace the <br /> overburden and topsoil in its final location quickly. As mining progresses, the operator will <br /> replace the overburden and topsoil by spreading it on the lakeshore slopes. <br /> Once stripping is completed, a dragline or front-end loader will commence the excavation of the <br /> deposits. Sand and gravel will be deposited into a windrow behind the dragline and will be <br /> stored for a period of two to four days to allow water to drain out of the material. Excess water <br /> from the windrow will drain back into the excavation. Front-end loaders will transport the <br /> material to a field conveyor, which will convey the material to the processing plant area. The <br /> field conveyors and or feeder will be relocated frequently during mining to minimize the travel <br /> distance for the loader. <br /> The mining operation will create permanent lakes. The Vendette Creek channel will terminate <br /> into Cell 3 with an outlet into Cell 4 eventually entering the Maryland Creek channel where it will <br /> flow into the Blue River east of Highway 9. The Maryland and Old Whetstone/ Sheep Creek <br /> channels will be preserved on dikes located between the lakes. In addition, the ditch along <br /> State Highway 9 will be preserved within a 50-foot setback from the highway right-of-way. Two <br /> (2) stormwater detention ponds are located in the process plant area to temporarily hold runoff <br /> water. <br /> Unmined areas will continue as grazing land for horses and cattle. Therefore, the buildings in <br /> the ranch headquarters will be maintained. <br /> Mining Cells 1 and 2 have been completed and partially reclaimed under the existing permit and <br /> subsequent Technical Revisions. Mining is actively occurring in Cell 3 and the top bench of Cell <br /> 4 has been stripped of topsoil and overburden. <br /> The rate of mining will directly relate to the demand for construction materials in the market <br /> area. Generally, the operator believes that mining activities from now until completion will <br /> progress according to the following timetable: <br /> Everist Materials,LLC-Maryland Creek Ranch Amendment#2 09034 <br /> M-1996-049 February 2010 <br /> Page 8 of 35 <br />
