On April 5, the Environmental Protection Agency (EPA) said it will release evaluation methodology for encapsulated coal ash reuse in the fall but will not regulate the approved uses. The methodology, which will allow users to compare the releases from products made with coal ash to similar products made without coal ash, will mainly apply to concrete and wallboard; however, states and stakeholders could apply the methodology to their products. A conceptual model for unencapsulated coal ash is expected to be released by the second quarter of FY14.
