Topsoil is <br /> removed only to the extent necessary to accommodate the mining operations. Through the mine <br /> plan,the rehandling of both topsoil and overburden is kept to a minimum.Reclamation of disturbed <br /> areas will commence as contemporaneously as possible. <br /> As necessary, mobile water truck will be assigned to work in topsoil or overburden removal <br /> operations to keep any dusty conditions under control. Planting of special windbreak vegetation in <br /> the permit area is not planned. <br /> Blasting <br /> Sequential blasting is utilized as a standard practice to reduce the amount of unconfined particulate <br /> matter produced. <br /> Complete blasting information is set forth in Section 2.05.3 and Sections 4.08.1 through 4.08.6. <br /> Fish and Wildlife Plan <br /> Prior to and during the early years of mining, Colowyo implemented wildlife management and <br /> range management programs to offset the potential impacts of mining on wildlife and to improve <br /> the rangeland in surrounding areas which had deteriorated after years of overgrazing. Other <br /> protection measures were also implemented to minimize any possible effects of the increased <br /> mining activity. <br /> Also, during the early stages of pre-planning for the mining operation, Colowyo adopted a policy <br /> to return the land to a condition capable of supporting the diverse wildlife populations that the area <br /> currently supports. The assumption in the late 1970s was that shrub reestablishment would play a <br /> key role in wildlife habitat mitigation. These early efforts were unique in that revegetation with <br /> shrub species,especially native shrub species,had never been an integral part of pre-mine planning <br /> in the West. Virtually no information was available and very little was known about the growth <br /> requirements of native species. To reach these early objectives, Colowyo implemented <br /> revegetation and wildlife habitat use studies designed to determine the feasibility and techniques <br /> of revegetating disturbed areas with native shrub vegetation adapted to northwest Colorado. <br /> However,after decades of experience, it has become obvious that reestablishment of shrubs on the <br /> reclaimed area is not critical to encourage wildlife use such as by elk. <br /> For example, in recent years it has been observed that elk herds of between 200 and 400 animals <br /> utilize the reclaimed grasslands of the mine as foraging habitat. These numbers increase to <br /> between 2000 and 4000 animals during the hunting season and then slowly drop off as the snow <br /> depths increase and the elk herds migrate to lower elevations. The animals return in the Spring for <br /> the early green-up. This occurs for at least three reasons: 1) elk are primarily grazers (grass <br /> Rule 2 Permits 2.05-41 Revision Date: 12/20/19 <br /> Revision No.: TR-135 <br />
