SUMMIT ENGINEERING C 0 1 ENGINEERS & LAND SURVEYORS <br /> Mail: P.O. Box 1897 Alamosa, CO 81101 P: 719-589-6147 E: summitengco@gmail.com <br /> Reclamation Plan <br /> Reclamation of the site will take place in phases as shown in those maps included in <br /> Exhibits C and F. Each phase of reclamation correlates to a phase of excavation. When <br /> one phase of excavation expires, reclamation of that particular phase will begin; thus, <br /> The Robins Rock Pit will be reclaimed as mining progresses. Mining operations should <br /> commence at the end of 2030, and the site should be fully reclaimed shortly after. <br /> Ultimately, the prominent defile in the cliff wall resulting from mining operations will be <br /> used as a livestock driveway after mining operations are completed. An outline of the <br /> plan is as follows: <br /> a) No overburden is expected to be encountered during mining operations because <br /> basalt rock outcrops are within a few inches of the surface. Thus, removal and <br /> replacement of overburden are not anticipated. <br /> b) Steep slopes exist throughout the permit boundary. These slopes are a result of <br /> the pit being located on a prominent escarpment that extends several miles in <br /> both directions. Consequently, there is little or no benefit to making all slopes <br /> within the site 3:1, particularly where the native slopes are more vertical in their <br /> original state. However, most areas affected by the excavation will not have <br /> slopes greater than 3:1, and all slopes that may occur further north and deeper in <br /> the mesa will not be greater than 3:1. <br /> c) The following measures will be taken to revegetate the site once mining <br /> operations have been completed. <br /> • When the excavation has been completed, top soil will be replaced to a <br /> depth of at least 6 inches and revegetated according to NRCS <br /> recommendations herewith. We estimate that approximately 18,000 CY of <br /> fine material will need to be moved from the stockpile an average distance <br /> of 400 feet with a rubber-tired load to get the material in place for final <br /> grading. <br /> • The site will be seeded immediately after mining has been completed, but <br /> in such a way that germinated seed will have time to grow prior to freezing <br /> weather. The seed bed will be disced and harrowed to eliminate <br /> compacted conditions. <br /> • The seed mixture is specified by the NRCS and is expected to be readily <br /> available in quantity from Arkansas Valley Seed Company as typical <br /> reclamation mix for the dry areas of the San Luis Valley. A mixture is <br /> enclosed with this exhibit. <br /> • The seed mixture will be broadcast with a utility vehicle towing a PTO <br /> (power take-off) driven broadcaster. <br /> Job # 1200710MP - A Pagel17of78 <br />
