All plant and equipment in the processing area <br /> is portable and would have more value that the cost of loading and removing it. <br /> Decommissioning will involve the removal of concrete pads for processing equipment, <br /> concrete supports for truck scales and temporary buildings, and the conveyor <br /> infrastructure and belting. <br /> Three 12-inch-thick concrete pads are assumed in the processing area with dimensions <br /> 15- x 30-feet, 15- x 60-feet, and 15- x 25-feet. Demolition and removal costs are <br /> estimated at $1.70/sq.ft. for 12"concrete pads. <br /> VARRA COMPANIES, INC.
