T;XNIBIT D <br /> Rule 6.3.4 <br /> Reclamation Plan <br /> Overburden will be stockpiled on site and replaced at the termination of the operation. <br /> Overburden will be distributed evenly across all areas where it was removed at an average depth <br /> of approximately 4 inches. <br /> (b) Reclaimed slope gradient: <br /> The extraction site currently exists as a roughly 1:1 slope. Because of the exposed nature of the <br /> rock,Applicant does not intend to dig any extraction pits. During reclamation, Applicant will <br /> grade the site to conform with the natural gradient and contours of the slope as required by 2 <br /> CCR 407-4 Rule 3.1.5(1). Applicant will leave the graded area at no more than a 3:1 slope, <br /> which will be possible after the material is removed. <br /> Applicant consulted with Edwin Friend, P.E., P.G., regarding Applicant's reclamation plan. Mr. <br /> Friend's recommendations can be found in the Van Valkenburg Quarry Storm Water <br /> Management Plan,attached as Exhibit D-2. Pursuant to Mr. Friend's recommendations, site <br /> grading will be developed so that concentrated drainage that could result in score does not occur. <br /> (c) Revegetation Measures to Reclaim the Site <br /> Applicant consulted with Mr. Friend and Debbi Heeney of Natural Resources Conservation <br /> Service(Walden, Colorado office)("NRCS") regarding Applicant's revegetation plan. As shown <br /> in Exhibit D-2, Mr. Friend recommended best management practices of reseeding any disturbed <br /> areas. Any topsoil previously removed will be replaced as plant growth medium.Applicant <br /> expects 12 inches of topsoil will be removed, as practicable. All topsoil will be evenly <br /> distributed over the areas from which it was removed,with an estimated depth of 4 inches. <br /> Ms. Heeney has recommended that the following live seed mixture be disbursed at a broadcast <br /> rate twice that required for seed drilling for dryland, upland areas south of Coalmont, Colorado: <br /> PLS Pounds per Approx.
