Once mining is complete and the slopes have been topsoiled, the diversion <br />ditch uphill of the pit will be removed to allow area surface water to enter the disturbed area. The <br />collection berm on the downhill edge of the disturbed area will also be removed to all surface water to <br />exit the pit area. <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 April, 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 Montrose 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 />0 Soderquist Pit March 10 13
