• i <br />EXHIBIT D (Cont'd) <br />annual operation in which a dragline, dozer and front-end <br />loader are used to excavate between two and seven feet of <br />- boulders, cobbles, pebbles and sand. The material is exposed; <br />there is no topsoil or overburden to be moved or stored. <br />After excavation, the naterial is moved directly to a portable <br />crusher on site. After crushing and sizing, the material is <br />moved off the affected land to a permanent concrete ready-mix <br />plant. <br />The mining of Stage 1 each year will commence after the <br />North Fork has subsided from the spring run-off. The small <br />amount of water running in the river will be routed along the <br />northwest bank of the riverbed so that the rest of the riverbed <br />and the southeast flood plain area may be excavated. In this <br />way there will be only momentary interruption of stream flow. <br />Stage 1 will be repeated annually, with the North Fork <br />~ filling the excavation left from the previous mining season <br />during the run-off each spring. The rock thus trapped in the <br />excavated area will not move on to aggrade the stream bed and <br />plague the Highway Department and downstream farms. Reclama- <br />tion will be a natural occurrence once each year in the spring. <br />In a very, very dry year the run-off might not entirely <br />fill the excavated area of Stage 1. In such event, the area <br />of Stage 2 and/or 3 might be excavated. Stage 2 would operate <br />and reclaim in the same manner as Stage 1. However, Stage 3 <br />6 <br />
