The American Coal Ash Association released its annual use survey November 27, concluding that uncertainty about how the Environmental Protection Agency will regulate coal ash is stalling the growth of reusing the material. The association charges that the agency’s potential regulation of coal ash as hazardous waste is preventing otherwise interested parties from using material in a host of applications; the agency said in October that it needs at least another year to complete its final rulemaking, but industry groups are hopeful that the Senate will act on related legislation during the lame duck session.
