Parkdale Quarry Expansion Exhibit E - Reclamation Plan 1. Introduction The original mining application, the 2008 amendment, and this amendment, all propose surface mining of sand and gravel and quarried granite aggregate at the Parkdale Quarry. Martin Marietta Materials has requested a Mineral Materials Competitive Sale, COC-078119, in order to expand operations at its privately-owned Parkdale Quarry onto adjacent Bureau of Land Management (BLM)-administered lands. The Parkdale Quarry is located in Fremont County, Colorado, approximately 12 road miles west of the Town of Canon City, Colorado. Martin Marietta proposes to expand operations generally north onto BLM property in portions of Sections 1, 2, 11, and 12, Township 18 South, Range 72 West, Sixth Prime Meridian (the Mineral Materials Sale Area). The location of the Parkdale Quarry and the onsite areas are shown on the Index Map in Exhibit B. The currently mined approximate 112-acre gravel extraction area is located between the Arkansas River and Tallahassee Creek. The current approximate 72-acre granite quarry is located on the opposite side (north) of Tallahassee Creek from the gravel extraction area. As part of the amendment process, the mining southern mining limit of the granite quarry on the private land will be moved approximately 900 feet north away from the Arkansas River. The amendment also removes the approximate 3-acre sandstone mining area from the area of permitted mining lands. As amended, mining is expected to disturb approximately 170 acres on the privately-owned portions of the quarry and approximately 700 acres in the BLM Mineral Materials Sale Area over the life of the mine. The Mineral Materials Sale Area is surrounded by an approximate 730-acre buffer that will be included in the mining permit boundaries, but will be left undisturbed. The purpose of the buffer is to provide a separation between the area where mining will occur and surrounding areas open to the public. Activities that create a ground disturbance will be restricted to the Mineral Materials Sale Area. Final mineral processing, loadout, offsite transportation, and associated activities will continue to be performed on Martin Marietta Materials’ owned property south of the Mineral Materials Sale Area. Activities that will be conducted on the Mineral Materials Sale Area include: • Construction and operation of access/haul roads and possible construction of a material handling and conveyor system from the Mineral Materials Sale Area to the processing area on the private land; • Excavation of mineral materials using explosives and/or heavy duty excavation equipment; • Loading of mineral materials onto haul trucks and/or an material handling and overland conveyor system for transport to the processing facilities on the adjacent private land; • Reclamation of disturbed areas in accordance with our reclamation plan, to be approved by BLM and the Colorado Department of Reclamation, Mining, and Safety.
