Environmental Protection Plan, Schwartzwalder Mine <br />19-1 <br />19. TAILINGS AND SLUDGE DISPOSAL <br />No tailings were disposed on the Schwartwalder Mine property. Ore from the Schwartzwalder Mine was <br />hauled to the Canon City mill for processing. <br />The original water treatment plant included drying trenches (settling or evaporation ponds), in which <br />barium chloride was used to precipitate radium. Sludge that accumulated in the drying trenches was <br />mucked out, mixed with ore, and taken to the Canon City mill for processing. A small quantity of sludge <br />from the sediment ponds was disposed on the east waste rock dump, prior to reclamation, and capped in <br />accordance with the mine reclamation plan (Cotter, 1983). Sampling of soils around and below the drying <br />trenches was conducted during reclamation, and the results met applicable cleanup criteria. Confirmation <br />sampling was conducted in September 2008, and included verification samples and monitoring using field <br />instruments The sampling confirmed that soils in the area of the drying trenches met applicable standards. <br />No other sludge disposal is known to have occurred on the property. <br />• <br />• <br />4109C.090807 Whetstone Associates
