PROJECT: Sherman Mine Reclamation and Sherman Mine Regrading Bond Number M-1986-141 Funding Sources—US BLM TO-26, Bond Forfeiture, and Severance Tax I. PROJECT OVERVIEW The goal of this project was to reclaim the Sherman mine site, located at an elevation of over 12,000 feet above sea level. The mine is located in Iowa Gulch, approximately 8 miles east of Leadville on the west flank of Mount Sherman, one of Colorado's 14,000 foot peaks. The mine had been idle for over 20 years, and the Colorado Mined Land Reclamation Board had revoked the permit. The Landowner, Bureau of Land Management (BLM) requested that Colorado Division of Reclamation, Mining and Safety (CDRMS) contract for the reclamation of the mine. CDRMS subsequently designed the project and solicited bids from interested contractors to perform this reclamation. The goal of the demolition phase of the project was to: • Reconstructing approximately 300 feet of access road • Re-establish the stream crossing • Remove power poles and power lines • Remove mine equipment, such as transformers and mine fan • Safeguard the ventilation portal with 60 inch corrugated metal pipe and locking door • Demolish all buildings, structures, foundations • Remove all steel and debris • Burn or haul off all timbers • Safeguard an additional adit with 36 inch corrugated metal pipe and grated locking door The goal of the regrading project was to return the mine area to its approximate original appearance and slope. To this end, the successful contractor reconstructed the access road and stream crossing, and cut and filled approximately 105,000 cubic yards of rock, then reestablished the original stream channel. Since this area receives public visitation, as one of the popular fourteener hiking trails passes near the site, the contractor was advised to be careful of pedestrians at all times, post signs explaining the project, and be prepared to interact with the public as they visit the site. The contractor was required to control public access to the active work areas to avoid potential hazards to the general public while providing access to the hiking trail. One pre bid was held in June 19, 2007 for both projects. The Reclamation Project was begun on August 21, 2007 and completed August 25, 2008, and the Regrading construction began on August 13, 2008 and was completed on October 1, 2008. II.
