RULE 2 PERMITS <br /> To support the proposed post-mining land use, small water impoundments (stock tanks) will be <br /> constructed to encourage an even distribution of grazing animals over the reclaimed site and to <br /> enhance the areas for wildlife. These small impoundments will also replace the existing water <br /> rights associated with the stock ponds that existed pre-mining. If necessary, Colowyo will submit <br /> designs for these small impoundments to the Division prior to their construction. <br /> Also, to provide access in the area for ranching purposes, the access road from Highway 13 will <br /> be left in place after mining is complete, and a number of"ranch roads" will be provided on the <br /> reclaimed area to approximate the roads that were in the area before mining. The access road <br /> will be narrowed from 26 to 12 feet,the asphalt removed, sideslopes reduced to 4:1 and the sides <br /> revegetated. <br /> The consideration of rangeland as a post-mining land use is identical to the discussion in Section <br /> 2.04.3. The limitations on changing to an alternative land use are fully discussed in that Section. <br /> Domestic livestock grazing will not commence until at least three years after seeding and shall <br /> be managed to promote the post-mining land use. Grazing will be managed in such a manner so <br /> as to not interfere or preclude the post-mining vegetation sampling as required in Section 4.15.8. <br /> 2.05.6 Mitigation of Surface Mining Operation Impacts <br /> Air Pollution Control Plan <br /> Colowyo maintains fugitive dust control measures as an integral part of all mining and <br /> reclamation activities. Presently, Colowyo operates under numerous Emission Permits issued <br /> from the Colorado Department of Health, Air Pollution Control Division, as more particularly <br /> described in Section 2.03.10. Copies of all applicable emission permits issued by the Colorado <br /> Department of Health are available onsite and can be reviewed by request. Colowyo conducts air <br /> quality monitoring at the site in accordance with the requirements of the emission permits. <br /> The principal fugitive dust control practices employed by Colowyo are as follows: <br /> Roads <br /> Colowyo employs a dust suppression program for in pit roads and other unpaved roads which <br /> primarily involves periodic watering. Mine water trucks run periodically as needed over the roads <br /> wetting down any dusty conditions. During the dryer months of the year,the water trucks will wet <br /> down the roads which are being utilized a minimum of two or three times per shift. If determined <br /> to be necessary as an addition to periodic watering, a chemical dust suppression agent may be used <br /> during the dry months on the primary in pit roads. To this date, however, chemical stabilization of <br /> the unpaved in pit roads has not been successful for more than a short period of time due to <br /> changing weather conditions and the use of heavy haulage trucks. <br /> Colowyo has surfaced"in-pit"roads with gravel or crushed rock;however,no roads in the pit area <br /> will be paved with asphalt. Asphalt could not sustain the enormous weights of the haulage <br /> Rule 2 Permits 2.05-39 Revision Date: 12/20/19 <br /> Revision No.: TR-135 <br />
