The sand and <br /> gravel is,currently removed using an excavator and loaded into trucks. for <br /> 'transport to the processing plant in the existing mine area. The processing <br /> plant.crushes and screens,the aggregate and separates it into various size <br /> factions to make the aggregate products sold on site. Aggregate products <br /> are shipped offsite by trucks owned by or contracted to KRC's customers. <br /> KRC does not provide on road trucking services to its customers. After the <br /> aggregate is removed from an area, the overburden is respread using dozers <br /> and motor graders. The maximum depth of mining is expected to be about <br /> 25 feet, but more typically about 10 feet. Working slopes will be no greater <br /> than those allowed by Cal OSHA and/or Federal MSHA regulations. Final <br /> slopes will approximate those that exist prior to mining and in no case will <br /> they be greater than 2 feet horizontal to 1 foot vertical. Typical cross <br /> sections illustrating premising, during mining and post mining slopes are <br /> provided in Exhibit W. Approximate post mining topography is illustrated <br /> in Exhibit VII and in cross section in Exhibit VI. Cross section locations <br /> are shown in Exhibit V. Due to the relatively thin layers of overburden, <br /> topsoil and the aggregate reserves itself, the post mining topography will be <br /> very similar to the premining topography. As shown in Exhibit 11, <br /> Phase/Topo Map, the Permit Area will be mined in three phases. Phase I <br /> consists of Phases Ia and Ib. In order to achieve aggregate quality <br /> requirements while maximizing recovery of the reserve, KRC proposes to <br /> mine Phases la and Ib concurrently in order to blend these materials. When <br /> mining is completed in Phase I (a and b), mining will commence in Phase <br /> I1. Phase 11 is segregated into Phases Ila, IIb and IIc in order to achieve <br /> quality requirements by blending aggregate from multiple sources. While <br /> mining is occurring in Phase 11 (a and b), Phase I will be reclaimed to <br /> rolling grassland by respreading overburden to be used as suitable plant <br /> growth materials and allowing for revegetation. When mining is completed <br /> in Phase II (a and b), mining will commence in Phase III (a and b) and <br /> reclamation will be completed in Phase I1. Reclamation in each phase will <br /> be ongoing to the extent possible. That is, as areas are mined out, <br /> overburden will be respread to achieve approximate original contours. <br /> However, reclamation cannot be completed until after mining is completed <br /> in any given phase. <br /> 4.
