16. Solid Waste Storage <br />A roll off container for disposal of trash will be located next to the shop. Small trash barrels may <br />be located near the office and dry-room. The trash will be picked up on a routine basis by a <br />service company and disposed of at an approved landfill. No landfills will be constructed on site. <br />Scrap metal will be stored in a bin and/or on pallets near the shop until it can be picked up for <br />recycling. Used batteries and tires will be stored in the same area and will be picked up and <br />recycled by vendors. <br />17. Ventilation Shafts <br />Three new ventilation shafts are proposed for the mine Each ventilation shaft permit area is 100 <br />feet x 100 feet in size, or 0.23 acres. These locations can be seen on Map C -5. The shafts will all <br />be installed from within the mine using the same methods as raises. Stripping topsoil from these <br />shafts prior to construction will not be practical, but any topsoil encountered at the top of the <br />shafts will be stored in a berm around the shaft exit to reduce surface water runoff inflows into <br />the shaft. A pad will be constructed at the top of each shaft. This pad will be concrete, 10' x 10' <br />square and 12 inches thick. The shaft openings will be up to six feet in diameter. The holes will <br />be cased and grouted as necessary to prevent any water from any potential upper aquifers from <br />entering the mine workings Almost all past exploration drilling in the Revenue/Virginius area <br />has been dry. Once the 960 shaft, Yellow Rose shaft and Monogahela shafts are complete, <br />secondary escapeway ladders will be installed in each shaft. Waste rock from the shaft <br />excavation will be brought out through the Revenue tunnel and delivered to the two <br />tailings /waste rock piles. <br />Revenue Mine August 2012 D - <br />
