Raw gravel assumes 1.5 t. <br />•' Note: Total azea is less than the permitted acreage. The remainder exists as undisturbed areas, roads, and <br />stockpiles. <br />Facilities and Mobile Equipment <br />All facilities for the site will be located in or around the pit Portable crushing, screening, <br />washing, cement, and asphalt plants will be brought onsite. A portable office trailer maybe <br />used for the scale house and offices onsite. An alternative office plan may use the existing <br />structures until mining progresses into those azeas. It is anticipated that processing facilities <br />will be kept in the pit bottom except during the mining of the initial phase. Processing of the <br />initial phase's gravel will occur on the existing surface of Phase 2. The topsoil will be stripped <br />to provide sufficient space for processing. <br />On-Site Facilities <br />Type Portable Notes <br />Crusher/Screen ~ <br />Asphalt Plant <br />Cement Plant (] <br />Office <br />Wash Plant <br />Scales <br />Fuel Farm ^ <br />The expected equipment used for this site can be seen below. <br />11/7/2005 Page D-6 <br />
