Coal-Ash Recyclers Seen Aided in EPA’s Water-Discharge Plan

Headwaters Inc. and other companies that recycle waste from coal-fired power plants may benefit from less-restrictive rules that U.S. regulators have signaled they may adopt.

In proposing rules covering the waste power plants send into waterways, the Environmental Protection Agency said it may regulate coal ash as “non-hazardous municipal and solid waste,” rather than as the more serious “hazardous substance.” The possibility of the more serious categorization being invoked had depressed the ash-recycling business, and risked undermining the industry, the companies had warned.
