• B~s and Gesso, LLC <br />Topsoil Segregation, Preservation, and Replacement <br />Temporary berms containing stockpiled topsoils will act as visual screening over <br />the life of the mine and are strategically located on the permit site to facilitate <br />easy access for reclamation. Temporary revegetation of topsoil stockpiles wil{ <br />occur if a stockpile is left undisturbed for more than one growing season and will <br />be maintained until the topsoil is reused in the reclamation process. <br />Final Grades <br />There will be a large amount of excess overburden obtained from the affected <br />areas of this mining permit. With topsoil thickness of approximately six inches, <br />overburden depth averages 5.7 ft. over the 68.7-acre area to be stripped and <br />excavated. The pre-mining process will salvage approximately 630,000 cubic <br />yards of overburden during the mining process. Processing fines from on-site <br />materials will generate another 125,000 cubic yards of fill. Combined overburden <br />and processing fines available to backfill Cell 1 and part of Cell 2 to near-grade <br />(ready for topsoil) totals 755,000 cubic yards. Approximately 514,000 CY of <br />material is needed to backfill the slopes of the mined areas to 3:1 or shallower <br />slopes, and another 78,000 CY is needed to backfill the northwest corner for <br />future commercial use. <br />Approximately 50,000 CY of topsoil will be salvaged during the pre-mining <br />process. Topsoil application will consist of approximately six inches and cover all <br />areas of disturbance. The acreage of disturbed areas equals 33.2 acres (24.4 <br />disturbed, plus 8.8 slope). The quantity of topsoil required as plant-growth <br />medium for the total 33.2 disturbed surface acres (including halfway down the <br />backfilled slopes), at a depth of 6 inches, will be approximately 27,000 cubic <br />yards. This leaves approximately 23,000 CY of topsoil in excess of the <br />reclamation requirements. Exhibit F, the Reclamation Plan Map, shows the <br />typical 3H:1 V slopes that will be created by final reclamation of the mining site. <br />GreeNCrofssant Property Sand and Gravel Mine.CDMG.112 Perrnd 20023 <br />Loveland Ready Mix Concrete, Inc. 14 March 2001 <br />
