SITE DESCRIPTION EXHIBIT B <br /> The site is located 7 . 8 miles northwest of Lyons, Colorado <br /> approximately 1000 feet east of HWY 36 at Pinewood Springs . The <br /> old mine area covers approximately 1 . 0 acre of the 9 . 99 acres ± <br /> being permitted. Additionally, the 2 . 84 acres that was partially <br /> disturbed in the existing Special ill permit is included to <br /> consolidate the two permits into one . The pre-law disturbed <br /> areas in both of the old permits are included in this amended <br /> permit because it has been redisturbed or may be disturbed in the <br /> future . The old mining area on the ill area will be leveled and <br /> used as a processing area if the quarrying option is ever imple- <br /> mented. <br /> The primary changes made in this amendment are the method of <br /> mining associate with the original dimension stone production <br /> facility and the addition of 8 . 99 acres to accommodate a surface <br /> quarrying operation to allow for better utilization of the <br /> material on the mine area . The particulars of these changes are <br /> explained in the Mining Plan text that follows . <br /> HISTORY: <br /> Mining began on the existing permit area in 1949 and has operated <br /> continuously since . In 1978 the first permit was issued by the <br /> Mined Land Reclamation Board for the one acre area that covers <br /> all of the current mining area excluding the under ground work- <br /> ings . Initially the drill and blast method was used to remove <br /> the rock. The highwalls currently on the site were created many <br /> years ago when the quarry first opened. There is a series of <br /> small steps (2 foot wide or less) that average 10 feet high on the <br /> existing face . The highest wall is approximately 60 feet high <br /> and is stable according to the geotechnical analysis . The main <br /> working area varies from 60 to 120 feet wide from the face and <br /> has a 5% slope so water will drain off . <br /> The blasting affected the rock quality meaning that much of <br /> the material mined was waste due to natural fractures or blast- <br /> ing. Some waste was also generated when processing took place to <br /> shape and polish the finished product . The waste material was <br /> dumped over the side of the hill creating the area shown on the <br /> maps as spill area. All of the spill areas were created pre- <br /> mining as noted in the existing permit and unless redisturbed <br /> 3 <br />
