EXHIBIT C <br /> Rule 6.3.3 <br /> Mining Plan <br /> (a) Commencement and Duration of Gravel Pit Operation: <br /> The gravel pit mining operation will commence upon receipt of approval from the Colorado <br /> Division of Reclamation, Mining, and Safety and receipt of other necessary permits. As gravel <br /> excavation and processing will be seasonal, this operation is intended to be an intermittent <br /> operation and used for less than one hundred and eighty days per year pursuant to the provisions <br /> of C.R.S. § 34-32.5-103(11)(b). The operation will last approximately 3 years from <br /> commencement. <br /> (b) Topsoil replacement depth: <br /> Approximately 12 inches of topsoil will be removed and stored on the western and southern <br /> boundaries of the site as shown in the attached Exhibit C-1, the Mining Plan Map, and replaced <br /> during reclamation. Removed topsoil will be reseeded as necessary to protect from erosion. Any <br /> necessary reseeding will utilize the seed mix and application methods described in the table <br /> below. Topsoil stockpiles will be stored in places and configurations to minimize erosion and <br /> located in areas where disturbance by ongoing mining operations will be minimized. Once <br /> stockpiled, the topsoil shall be rehandled as little as possible until replacement on the regraded, <br /> disturbed area. <br /> Seed mix for use on Topsoil/Overburden Stockpiles and Extended Access Road Drainage <br /> Diversion Ditches to be applied at a rate of 101bs/ac <br /> Intermediate Wheatgrass 30% <br /> Slender Wheatgrass 25% <br /> Pubescent Wheatgrass 25% <br /> Russian Wildrve 10% <br /> Western Wheatgrass 10% <br /> Total: 10lbs/acre <br /> (c) Thickness of overburden: <br /> Approximately 12 inches of overburden will be removed in advance of deposit removal and <br /> stored temporarily in the southwestern corner of the pit. This overburden will be marketed as a <br /> secondary product and removed from the site shortly after excavation. If in place for more than <br /> 180 days overburden stockpiles will be seeded with the seed mix identified in section (b), above. <br /> (d) Thickness of deposit to be mined: <br /> The Applicant currently estimates that the deposit to be mined may be approximately 15 feet <br /> thick. <br /> (e) Major Components of Mining Operations: <br /> Oak Creek Consulting and Production Services,LLC Page Iof 4 <br /> Construction Materials Limited Impact(110(c))Operation Reclamation Permit Application Form <br />
