<br />5. Mining Plan (Exhibit D) <br />Removal of flagstone (primary commodity) and moss rock (secondary commodity) are proposed <br />for the site. The material will be sold for use in construction and landscaping. Past rock removal <br />has been confined to the existing rock slides where there was no soil or vegetative cover. There <br />was no overburden to remove from the slides and there was very limited waste rock generated by <br />the operation. The rock slides will continue to be worked in this manner for recovery of moss <br />rock and flagstone. Waste rock generated by the operation will be hauled to the staging area and <br />placed in a mechanical tumbler. These tumbled rocks will be sold as pavers for landscaping and <br />walkways. <br />Mining of the rock slides will invoh~e use of heavy equipment, including a caterpillar tractor, <br />front end loader, haul truck, and fork lift. The caterpillar and front end loader will be used to <br />move rock at the toe of the slides to create an equipment staging area such as the one already <br />created at the toe of the largest slide. Then the rock will be loaded into a haul truck with the <br />fmut end loader and taken to the staging area for sorting onto pallets for transport. As the rock is <br />removed from the toe of the slide, gravity will move more rock into place and work will continue <br />until all desirable rock is removed. 'Then a new equipment staging area will be col higher on the <br />slide and the process will be repeated until the top of the slide is reached . There will still be <br />t'ock left on each slide after mining is completed and regrading will restore the natural <br />appearance of a rock slide. The rock is unmineralized sandstone and does not represent a <br />potential source of acid mine drainage. <br />Mining of the flagstone outcrops will also involve use of heavy equipment, including a caterpillar <br />tractor, front end loader, haul truck, and fork lift. The caterpillar and front end loader will be <br />used to construct terraces in the hogback starting from the top and working down the ridge. Each <br />terrace will be approximately 20 feet high and 20 ft wide and have a headwall sloping at about <br />75" which is the average dip of the bedrock (pigure I). There will eventually be about l0 of <br />
