Executive Summary of T-Bone Stone Quarry (110) Operation Reclamation Application <br />Aprit 21, 2004 <br />Page 3 <br />be necessary and appropriate to promote slope stabilization and enhance safe passage for wildlife <br />traveling through the reclaimed quazry area in the future. <br />The first 12 inches of soil consists of very stony loamy fine sand (see Exhibit B ). Because this <br />material is primazity rock and sand, it does not support significant vegetation. The intended future <br />use for the area is rangeland, which wilt be reestablished by revegetating with amix ofnative grasses <br />in a manner and amount specified by Boulder County in the Revegetation and Native Grasses <br />Publications included in Exhibit D, and by reestablishing native Ponderosa Pine @ ten trees per acre <br />and Rocky Mountain Juniper shrubs @ five per acre. <br />Environmenfal Impacts <br />The current condition of the area of the property proposed for quarrying includes an historic quarry <br />that was abandoned more than fifty years ago. When the historic quarry was developed, many of the <br />reclamation and revegetation standazds that now regulate 110 projects and that are now governed by <br />the State of Colorado's Mined Land Reclamation statute did not exist. The demand for Lyons Red <br />Sandstone as a construction material throughout the Front Range and elsewhere in the United States <br />continues to exist Modem mining and reclamation techniques will restore the site effectively to a <br />natural condition and eventually reclaim the site, including the unreclaimed quarry found in TBS 2. <br />See T-Bone Stone Mining Plan Map. <br />The T-Bone Stone Site Plan illustrates how this wilt be accomplished The proposed mining and <br />reclamation plan will result in improved erosion control in areas of the site that aze too steep for <br />permanent reclamation today. Regrading of the quarry will actor on an ongoing basis during the <br />quarry's productive period, which is estimated to be fifty (50) years or more. Revegetation (with <br />drought taterani seed in accordance with County regulations and recattunendations) of the areas <br />within the State of Colorado § 110 permit areas, will commence after final grade is reached and the <br />stone deposits have been removed. <br />T-Bone Stone's reclamation plan will use waste rock and stockpiled overburden to complete the <br />property's restoration. The quarry will be left in a condition that will continue to provide important <br />connections for wildlife in the area, and it will serve important buffering functions for habitat, <br />wetlands or riparian areas. <br />Boulder County Limited Impact Specla! Review Permit Not Required <br />Boulder County Land Use Code §4-508 (A), def nes "Limited Impact Open Mining" as follows: "the <br />extraction of earth materials by mining directly from the exposed deposits or other materials where <br />mining operatians affect less than Yen acres of land within a parcel. T-Bone Stone is applying for a <br />Colorado I 10 permit, which is limited to tea acres. The exception provision, §4-508 (A) (5} (ii), <br />provides that a quarry which "extracts less than 3,600 tons per year" is not required to go through <br />the LISR process. <br />rand use & DevdopnYnr Prauainvg- Bsesiness Formelion & Employe, Defense - GovernmmY.f Public Aelalioms <br />Phone: 343.4472i5i O F,4X: 343.447.1635 O Ce[/ Phone: 343.9315089 O &muit: edbyrn~smartlanduse.com <br />
