EPA Proposed Fly Ash Rule Frequently Asked Questions

 1. What is EPA's proposal on coal ash?
EPA is proposing the first-ever national rules to ensure the safe disposal and management of coal ash from coal-fired power plants under the nation’s primary law for regulating solid waste, the Resource Conservation and Recovery Act (RCRA).  
We have put forward two proposals that reflect different approaches to managing the disposal of coal ash and are inviting public comments on these two options.

From Waste to Efficiency

(Business Lexington 4-20-2010) For decades, fly ash, one of the residues generated in the burning of coal, especially at coal-fired power plants, was released into Kentucky's skies. Today, by law, fly ash is captured in the chimneys of those plants. Some of the companies in Kentucky that collect that fly ash include Kentucky Utilities, Louisville Gas and Electric, Cincinnati Gas and Electric and Kentucky Power. 

Coal Ash Rule Still On Track?

(OMB Watch 4-27-2010) The U.S. Environmental Protection Agency still plans to issue a proposal for the regulation of coal ash in the coming weeks, according to the agency’s most recent regulatory agenda.EPA projected an April release date for the proposal. The timeline is found in the semiannual Unified Agenda of Regulatory and Deregulatory Actions which Executive Branch agencies published today. The details of the proposal are not indicated.

Recycling Transforms Fly Ash Into Eco-Minerals

(Engineering Live 4-27-2010) RockTron's new plant at Fiddler's Ferry in Widnes, Cheshire, UK (Fig. 1), can recycle 800,000 tonnes of fly ash a year. It is designed to process both fresh and stockpiled fly ash, effectively solving the problems of large-scale waste storage and removal, site remediation and conservation of natural resources. This GGBS, or CEM I (Portland cement (PC)) substitution proposition, allows companies to cut their costs, increase their margins and maintain their bottom line. RockTron is currently negotiating new plants in the US, Malaysia and Russia.
