processing. The crew also drives a pick up to and from the site on the days harvesting occurs. See Figure <br /> 1 in Exhibit A, Exhibit C and Exhibit F. <br /> No buildings or processing equipment are required as the rock will be hauled to another location for <br /> processing. The existing slopes on the surface range from 5 to 60 percent. See Exhibit C Mine Plan. The <br /> slopes are expected to be stable since the angular nature of the talus material stabilizes the rubble material <br /> and any soil present. TR-01 was approved in 2001 for the ramp constructed up the slope to the previous <br /> harvesting area in the northeast corner of the Marble Airfield, LLC property and the use of 2:1 H:V <br /> slopes for reclamation. The ramp constructed on the Marble Airfield property has been left for <br /> landowner use and is not used as the property has been removed from the permit area by Technical <br /> Revision AR-3 in 2015. <br /> On USFS lands, tree islands greater than 20 feet in diameter and individual conifer trees greater than 3 <br /> inches dbh will be avoided. All standing trees and snags will be left in place for cavity nesting birds and <br /> wildlife cover. No tree clearing for harvesting operations will occur without prior authorization from the <br /> USFS. To date, disturbed acreage has ranged from 0.0 to 0.64 acres annually while the reclaimed acreage <br /> has ranged from 0.0 to 0.82 acres annually. The contemporaneous reclamation practice keeps the net <br /> disturbed acreage less than 1 acre. Contemporaneous reclamation will be continued on the USFS lands. <br /> Storm water from the harvesting area will be directed through a series of check dams in a ditch and silt <br /> fence prior to discharge onto the talus slope. If the harvesting uncovers more talus slope material only, <br /> then no sediment control is anticipated as this condition represents the historic drainage condition. No <br /> impoundment or detention facilities are needed. <br /> Topsoil or plant growth medium is present in small areas under trees and shrubs. To date insufficient <br /> topsoil has been encountered to warrant stockpiling. Topsoil material exposed during the grading of the <br /> disturbed slopes is seeded and mulched. If no plant growth medium material is encountered, the <br /> remaining rock surfaces will be graded to match the natural slope or a 2:1 H:V which ever is flatter. On <br /> USFS land the harvested area be regraded only. The larger trees, plus 12" diameter, will be left in place <br /> to enhance the post mining land use. <br /> The current weed control plan of inspection and spot spraying of weeds will continue per the letter from <br /> Gunnison County(on file with 112 permit). On the USFS lands, the weed control plan will be <br /> supplemented by the weed control practices that are in accordance with the WRNF Invasive Plant Species <br /> Management EA (FS2007). Preventative action will include cleaning of vehicles and equipment prior to <br /> bringing them into the project area. <br /> The harvesting area is located at elevation 8,000 which is approximately 190 feet above the Crystal River. <br /> The harvesting operation is not expected to encounter any ground water. No impacts to existing water <br /> rights are anticipated because no water is required for the operation. No refuse and acid toxic producing <br /> materials are present in the talus slope. No explosives are used in the harvesting activities. Equipment <br /> will be fueled from tanks mounted in the back of pick-up trucks. No storage of fuel in tanks on site is <br /> anticipated. The primary commodity to be harvested is the angular and moss rock on the talus slope. No <br /> secondary commodities are present on the talus slope. The primary product is building stone. <br /> Revised: 09/18/2018. <br /> 6 <br />
