About this file
This is an Inactive Mine Site Field Form document prepared by the Colorado Division of Reclamation, Mining, and Safety for the Brasscap Project (OSM Project #561), focused on mine site closure work in San Juan County, Colorado. The document details five separate inactive mine features requiring remediation work within the Poughkeepsie project area, accessed via Highway 550 near Ouray and Engineer Pass roads. The work involves closure of five mine openings: the Bannock Burne adit (Project ID 06), Fire King Lode prospect shaft (ID 07), and three Brooklyn and Unpatented USFS adits (IDs 08, 09, and 10). Preferred closure methods include installation of bat grates with access doors, bat ladders, and drainage infrastructure, with bulkhead alternatives available at contractor discretion. Mine dump volumes range from 50 to 100 cubic yards across the sites. All features are located on USFS or BLM land used for recreation and wildlife, with depths ranging from greater than 20 feet to greater than 150 feet. Access to all sites requires four-wheel-drive vehicles, and good equipment access is not available at any location.
The document indicates that four of the five features present possible bat habitat requiring protective measures during closure, with USFS wildlife biologist Andrea Wong providing clearance determinations. Specific closure work specifications reference Standard Work Specifications (SWS 11 and SWS 8) for grate installation, concrete footers, and drain pipe installation. No pricing information, contract terms, funding sources, or award dates are included in this field assessment document. The survey was conducted on September 6, 2012, by Project Manager CJL, and the document serves as the preliminary technical basis for determining closure requirements and contractor scope of work for these inactive mine sites.
