area in Marble adds an additional 0.9 acres, resulting in a total permit disturbance of 6.4 acres. However, <br />the amount of land to be re- vegetated is limited to a portion of the access roads on the surface of the <br />waste piles. Nevertheless, the total 6.4 acres is assumed to be revegetated at the end of the mine life. <br />3. Post - Reclamation Site Drainage <br />The system of collection ditched and sumps will be left in place for final reclamation. These areas will <br />be seeded and mulched and will re- vegetate. As they eventually silt in, the site will be re- vegetated and <br />the system should not then be needed. Once mining is complete, drainage from the quarry will <br />commence when water has filled the existing workings up to the lowest possible exit elevation. This is <br />the north portal. Water exiting the north portal will continue down the access road. <br />4. Weed Control <br />Measures will be employed for control of any noxious weed species. A Weed Control Plan will be <br />utilized as follows: <br />1) Each June, a weed survey will be made of the permit area. <br />2) If any patches or plants have been identified, they will be sprayed by backpack sprayer or 4- <br />wheeler using chemicals approved for use by the weed control staff of Gunnison County. <br />3) After reclamation, weed surveys and spraying will continue until the perennial cover and <br />production of the site have met DRMS requirements and bond release has been obtained. <br />The Division and Gunnison County weed control staff will be consulted regarding any weed infestation <br />area and any control measures before they are instigated. The plan does not contemplate total weed <br />removal on the property. Past experience shows that some initial weed cover in the first year following <br />the revegetation of an area can be beneficial. Weeds tend to provide shade for new growth, are a means <br />of holding snow on the seedbed longer and protect it from wind and water erosion until the planted <br />species have taken hold. <br />During the removal of overburden, if an area of heavy seed infestation is encountered, it will be buried <br />in the slopes rather than used as a growth medium. During all phases of the mining operation, the area <br />Yule Quarry January 2014 58 <br />
