6.3.3 EXHIBIT C <br />Mining Plan <br />6.3.3 Mining Plan description: <br />The purpose of the mining plan is to describe how mining will affect the permit area for the <br />duration of the operation. This plan must be correlated to Exhibit E — Map. The description of the <br />mining plan must be adequate to satisfy the requirements of Section 3.1 and demonstrate <br />compliance with Rule 3. At a minimum, the Operator/Applicant must include the following <br />information: <br />(1) The purpose of the mining plan is to describe how mining will affect the permit area for <br />the duration of the operation. This plan must be correlated to Exhibit E — Map: <br />(a) The estimated dates mining will begin and end. if the operation is <br />intended to be an intermittent operation as defined in by statute, the Applicant <br />should include in this exhibit a statement that conforms to the provisions of the <br />Statutory requirements: <br />• The proposed operation will not be an intermittent mining operation. <br />• Mining operations will begin once all required permits are in place. This is a <br />CDOT roadway project and removal of the borrow material from the site should <br />require less than nine months once the project begins. Removal of borrow <br />material from the site and site reclamation should be completed prior to the end <br />of 2020. <br />(b) The estimated depth topsoil will be salvaged, specify how the topsoil will be <br />stockpiled and stabilized with a vegetative cover or other means until used in <br />reclamation. Topsoil stockpiles must be protected from mine operations traffic, <br />stream channels or drainageways. The location must be shown on Exhibit E — Map: <br />• The part of the proposed borrow area is an historic borrow area. As such, there is <br />very little topsoil present on the southern �-� of the site. Soils Unit 106 has very <br />little topsoil. The top 0-3 inches is a sandy loam. Below twelve inches is <br />bedrock. We will therefore strip no more than 6 inches off of soils Unit 106. <br />This unit comprises approximately 3.8 acres of the proposed Borrow area. <br />• The other soils unit is Unit 7. This l Jnit has the deepest soils. It only comprises <br />about 1.4 acres of the proposed borrow area. In this Unit, the top 6 inches is a <br />sandy loam. From 6 inches to 19 inches is a sandy clay loam. We will take 18 <br />inches of topsoil from this Unit (3, 6 inch lifts). The total plant growth material <br />available from this Unit is approximately 3.38E cubic yards. <br />• Using 6 inches of plant growth material stripped from soils Unit 106, over 3.8 <br />acres which is available for stripping, equals approximately 3,065.9 cubic yards <br />of plant growth material. <br />• Replacing 6 inches of plant growth material over an estimated 26.95 acres of <br />Revised page D <br />
