50 • January 2015 www.concreteproducts.com Charlotte-based Duke Energy is reviewing through early next month responses to a late-2014 request for proposals on a study of ways to benefi- cially reuse coal ash, plus analysis of current and emerging technologies. It encouraged industry specialists, academic institutions, research organiza- tions and those with coal ash expertise to register to participate, registering at CoalAshReuse@duke-energy.com. "We are eager to expand the amount of ash directed to the beneficial reuse market," says Duke Energy's John Elnitsky, senior vice president for ash management strategy. "A full assessment of the available technologies and innovations will help us integrate solutions that are safe, practical and proven for large-scale applications." The RFP calls for a study focusing on three key areas related to coal com- bustion products: 1) market analysis of beneficial reuse opportunities in the concrete industry or other sectors; 2) assessment of new processing technol- ogies to enhance the material's suitability for beneficial reuse; and, 3) an examination of all innovative technologies that might be applied to recycle, reuse or mitigate the impact of existing or newly generated coal ash. Study results will advance Duke Energy's efforts to strengthen ash management strategies, as well as work to permanently and safely close ash basins across North Carolina, where it has 14 power generating stations. The utility has established a national advisory panel of independent experts in partnership with the University of North Carolina at Charlotte to provide counsel on permanent coal ash storage solutions across the enter- prise. It also created a dedicated, in-house organization to rigorously man- age all coal ash handling, storage and marketing. More information can be found at www.duke-energy.com/ash-management. BRIEFS MANUFACTURERS Major utility looks to boost fly ash, other coal combustion product usage Coal combustion products (CCP) management specialist Charah Inc. has entered into or renewed agreements involving three Louisville Gas & Electric Co. and Kentucky Utilities Co. facili- ties: Mill Creek Generating Station in Jefferson County, Trimble County Generating Station, and Ghent Generating Station near Carrollton, Ky. The Louisville-based operator expects to market the stations' fly ash to ready mixed producers throughout the Midwest, providing them multiple supply options of high qual- ity, ASTM C618 Class F product. Charah underscores the dual benefit of marketing con- crete-grade ash, as it reduces carbon dioxide emissions attrib- utable to the partial replacement of portland cement, and landfill-bound material volume. "We believe our innovative solutions will continue to pay dividends for our utility partners and their consumers, and are proud to have been LG&E; and KU's partner since 1998," says CEO Charles Price. "We will be able to ensure a steady and reliable supply of ash for the ready mixed concrete producers during a time of substantial change in the utility and fly ash industry." CHARAH CONTRACTS EXTEND C618-GRADE ASH OPTIONS FOR MIDWEST PRODUCERS Your job demands durability from your vehicle and your body. With the Air Link ® tandem drive suspension, you can reduce wear on both. By combining a walking beam with an air suspension, you get superior traction when the load is full without the bone-jarring ride when empty. All this while reducing maintenance costs and downtime.
