Problem: Beginning in October of 2000, PHC Reclamation, Inc. (PHC-REC) performed site investigation, site hazard assessment and on-site fieldwork for AML Project 17F-5 located within the Gebo-Crosby coal-mining district near the historic ghost town of Gebo, Wyoming.  PHC-REC had to eliminate the public safety hazards associated with abandoned underground and surface coal mine sites.
	Objective: The purpose of the project was to evaluate and eliminate the public safety hazards associated with abandoned underground and surface coal mine sites while preserving the historic values of the Bighorn Basin's coal mining history.  To ensure that the historic significance of the area was preserved and documented, PHC-REC, in association with Rosenberg Historical Consultants, prepared a National Register of Historic Places Report and Multiple Property Documentation Form.  The Form identifies the historic context and includes a narrative of the coal mining performed in the Bighorn Basin from 1890 - 1950.   [click here for Wyoming BLM information ]
	PHC Solutions: PHC-REC inventoried, investigated and prepared reclamation designs to mitigate the hazards associated with highwalls, open or partially collapsed portals, exploration trenches and pits, vertical openings, adits, subsidence features, unstable spoil and gob piles, dilapidated buildings and equipment, geomorphic instability, on-site and off-site erosion and degradation, and hazardous materials.  Phase II included the mitigation of five (5) underground coal mine mines and a series of five (5) exploration trenches with dangerous highwalls.  A bat grate was installed in HOTS0024-2. link
