INTRODUCTION Agile Stone Systems' Pazkdale Project application (M-1997-54) was found complete and considered filed with the Division on July 8, 1997. The original application, and this amendment, both propose surface mining of gavel, quarried granite aggregate and quarried sandstone at a site located 10 miles west of Canon City, Colorado, in an azea just upstream of the confluence of the Arkansas River and Tallahassee Creek. The project area is adjacent to the Union Pacific Railroad (UPRR) which runs along the north side of the river channel. This amendment proposes to change the mining and reclamation plans for both the sand and gravel mine and the granite quarry. On behalf of Front Range Aggregates, Applegate Group, Inc. (Applegate), has prepared this report to amend the Regular (112) Mining and Reclamation Permit (M-1997-54). The mining and reclamation plans for the granite quarry were prepared by Lyman Henn, Inc. (Lyman Henn). This amendment was prepared in compliance with the Rules and Regulations established by the State of Colorado through the Mined Land Reclamation Act, the Division of Reclamation, Mining and Safety (DBMS), and the Mined Land Reclamation Board (Board). SANDSTONE QUARRY The existing permit contains a 3-acre sandstone quarry, located on the north side of Tallahassee Creek. This amendment does not affect or propose to change any mining or reclamation regarding the sandstone quarry. SAND AND GRAVEL The original permit proposed mining 54.8 acres within the 100-acre mining limit located between the river and Tallahassee Creek. The processing plant was to be established 8 feet below the existing ground elevation but mining was to occur to the east and west of the processing plant. This amendment proposes to expand the gravel mining limit to a proposed 112-acre gravel extraction area, including the processing plant area. The original permit proposed a reclamation plan of open space and dry land pasture. This amendment proposes to reclaim the sand and gravel mining area as a dry hole sealed with a clay liner and 3H:1 V sloped embanlanents. The hole will be built with a clay liner designed to meet the criteria for a lined water storage vessel. GRANITE QUARRY The existing permit contains a 64.3-acre ganite quarry, located on the opposite side (north) of Tallahassee Creek. The quarry encompasses the southwest side of Cactus Mountain, north of Front Range Aggregates' active gravel mining operation. The original permit proposed a mining depth of elevation 5780 feet and a reclamation plan incorporating wildlife habitat and open space. This amendment proposes a new disturbance limit of approximately 83 acres and a new limit of mining to contain approximately 72.5 acres. This permit amendment will allow Front Range Aggregates to mine to a bottom elevation of 5300 feet above sea level. The final land use for the granite quarry will include an empty reservoir below the elevation of 5800 feet. The granite benches will form the reservoir embankments. The stability and permeability of the granite will be evaluated as mining and reclamation proceed. Fran! Range Rggrega[es, LLC- Pnrlalale Qaarry DMG 172 Permit Amendment Page 1
