~J EXHIBIT "B'• MINING PLAN. This site originally was an exposed decomposed granite dome. Past mining operations have flattened the site to where it now has a mesa-like appearance. It slopes uniformly to the east. The affected area presently measures 3.4 acres. The Copsoil varies in thickness Erom 0 to 6 inches and is neatly stockpiled for reclamation on the outside perimeters of the mined area. The top is flattened creating a berm approximately 12 inches above the mined area to contain and prevent runoff. The downstream slope averages 3: 1. Overburden and waste material is minimal. The mined material is of satisfactory quality for rural road construction and maintenance and is sold as pit run. Customers furnish their own trucks for hauling. When mining operations resume it is planned to remove gravel in 18 to 24 inch layers beginning at the west end and moving to the east. Depth of workable deposit is estimated at 20 to 25 feet. Extraction rates are projected at 8,000 to 12,000 tons per year maxium. Mining operations a}e planned for 20. years pr less. The owner uses a dozer for stripping and ripping and a front-end loader for loading. There is no fixed equipment at the site. Whea the County Road and Bridge Department need gravel for projects in the Rye area they move in their dozer, front-end loader and occasion- ally a portable screening machine to remove oversize material. Entrance and exit is on an existing ranch road from Highway 165. Gates are locked when there is no activity at the site. As provided in Rule 1, "General Provision 1.62", the applicant hereby states that the affected lands are to be used for less than one hundred eighty (180) days per year. That portion of the ranch road within the affected area although used in routine ranching activities will be reclaimed after mining operations cease.
