11 Summer 2014 the Professional Engineer Indeed, most other countries consider coal ash as a product. Te re-use rates in European countries, for example, approach 100%. In the U.S., EPA, Federal Highway Administration and many states have encouraged CFA use. Up until its 2010 proposed rule, EPA has consistently supported CFA use. Te best example of this is the Coal Combustion Products Partnership: "Te Coal Combustion Products Partnership (C2P2) Program is a cooperative efort between EPA and the American Coal Ash Association (ACAA), Utility Solid Waste Activities Group (USWAG), Department of Energy (DOE), Federal Highway Administration (FHWA), and the United States Department of Agriculture (USDA) to promote the benefcial use of CCPs and the environmental benefts that result from their use." A goal of C2P2 was to increase the use of coal combustion products to 50% in 2011 from 32% in 2001. Tese rates have been undermined in part by a weak economy and regulatory uncertainty. North Carolina needs a new partnership that could involve N.C. Department of the Environment and Natural Resources, N.C. Department of Transportation, Duke Energy as well as various ash marketers and engineering frms. As with any construction material, CFA must be managed properly. It shouldn't be discharged directly in a river, as happened in the Dan River on Feb. 2. It was the third such spill in U.S. history. Te primary impact on the Dan River spill has been fne ash particles making the water cloudy. Analytical results indicate no diference between post-spill upstream and downstream contaminant concentrations when the sample was fltered. Te infuence is measurable when analyzing unfltered samples, as one might imagine from the gray-col- ored Dan River shortly after the release. After analyzing for more than 40 constituents, the impact can be summarized in terms of four
