MINING PLAN 1. General Plan- Mining EXHIBIT D Up to the permit amendment in 2002, the original Berry Pit permit area consisted of approximately 50 acres. The gravel zone was approximately 20 feet thick and was overlain by soil and overburden of 2-18 feet. The average thickness of soil/overburden was 12 feet. The topsoil/overburden was stockpiled on the north side of the permit area as shown on Map C-2. This soil and overburden will be used to reclaim the original permit area. The area was mined by first excavating soil/overburden with scrapers or front end loaders and stockpiling the material on the north of the pit. The raw gravel material was placed in a portable crusher/screen plant and various sizes of product were made and placed in separate stockpiles. The 2002 amendment was made to allow mining of the adjacent area to the south of the original area. This results in a total permit area of 91.21 acres. The total disturbed area is 67.5 acres. The breakdown of this acreage given below is based on a worst case disturbance for the life of the pit: Area Description Acreage 1. Soil/Overburden Stockpiles 4.5 2. Processing area 8.0 3. Product stockpile area 5.0 4. Active Mining area (including topsoil stripping, active pit, roads) 28.0 5. Fully reclaimed areas 10.0 6. Partially reclaimed areas 12.0 Total 67.5 Dozers, loaders and trucks may be used to mine the gravel and haul it to the processing plant. This plant consists of a portable rock crusher and screen plant to obtain the desired material sizes. Cer- tain sizes may be used as feed for an on-site portable concrete plant and portable asphalt plant. Up to 4 portable stacker conveyors are used to stockpile the various sizes of material. Processed mate- rial is stored in stockpile areas as shown on Map C-2. Hot bituminous pavement made on site is not Berry Pit 3/02 6
