The remainder exists as undisturbed areas, roads, and <br />stockpiles. <br />11. Facilities and Mobile Equipment <br />All facilities will be portable or semi-portable on this site. Some of the facilities will be located at <br />the extreme southeast corner of the permit area, which is located outside the 100 year floodplain of <br />the Colorado River. On Map C-2, this area is shown as Mining Area 2 - Phase 4. The facilities <br />include a truck scale, office trailer with potable water, porto-poties, and truck loading area. A <br />crusher & screen plant, portable asphalt, portable concrete, and potentially a wash plant will also <br />be located in this area during initial mining of Mining Area 2. Once sufficient room is opened at <br />the bottom of the pit, these facilities will be moved to the pit bottom. This is normal for almost all <br />wet pit operations. The scale and office trailer will be very portable in nature and will be moved as <br />necessary. All portable plants are licensed and permitted individually. <br />No permanently stationed mobile equipment is anticipated for this site. Various pieces of mobile <br />equipment will be brought onsite to meet current needs. For instance, when the portable crusher is <br />brought onsite to produce aggregate products, all necessary mobile equipment will accompany the <br />portable plant. After the plant has completed its goal, the plant and mobile equipment will be <br />moved to the next pit to crush there. If a piece of equipment is permanently stationed at the site it <br />will be registered with the County. No permanent asphalt and concrete plants area allowed on this <br />site. All portable asphalt and concrete plants are only allowed on site from July 15 to November 15 <br />of any year unless Garfield County approves a change to this timeframe. <br />Scott Pit March 10 D-10
