EPA Announces Plan to Regulate Coal Ash

(EPA 5-4-2010) The U.S. Environmental Protection Agency today is proposing the first-ever national rules to ensure the safe disposal and management of coal ash from coal-fired power plants. 
 

EPA Proposes Coal Ash Rule, Sets Time for Comment

 (Associated Press 5-4-2010) The Environmental Protection Agency on Tuesday proposed regulating coal ash, possibly as a kind of hazardous waste, while phasing out wet storage impoundments. It would allow coal byproducts to be used in concrete, wallboard and other building materials.
 

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. 
 

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.
 

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.
 

Eyjafjallajokull Volcanic Ash: Can it Be Used as Substitute for Portland Cement?

(Green Buildings 4-23-10)  John asks: With the Eyjafjallajokull eruption in Iceland, is there an opportunity to use the volcanic ash as a substitute in concrete? Can volcanic ash mix with calcium hydroxide the same way that fly ash does?
 

No Current Risk from Golf Course Fly Ash EPA Says

(Virginia Pilot 4-23-10) After an investigation that stretched for nearly two years, a contractor for the U.S. Environmental Protection Agency has concluded that contaminants found in the water under a Chesapeake golf course sculpted from fly ash pose no public health threat.
 
The conclusion effectively ends the federal agency's involvement and means the Battlefield Golf Club at Centerville will not land on a list of the nation's most contaminated properties.
 

Evironmental Council of the United States "Resolution 8-14 Regulation of Coal Ash"

The Resolution was revised to acknowledge EPA’s CCB rulemaking effort and states that “if U.S. EPA promulgates a federal regulatory program for state CCW waste management programs, the regulations must be developed under RCRA Subtitle D rather than RCRA Subtitle C.” In addition to opposing hazardous waste regulations as unnecessary to ensure the proposed management of CCBs, ECOS confirms its position that “designating CCW a hazardous waste under RCRA Subtitle C could create stigma and liability concerns that could impact the beneficial use of CCW.”\

Let's Clear Up the Fly Ash Dilemma: Is it Danger or is it Not?

(Engineering News Record 4-14-2010) There’s plenty of irony in the possibility that fly ash, a by-product of coal combustion, now may be classified as a hazardous waste by the U.S. Environmental Protection Agency. It has been successfully recycled for years in what previously had been considered an environmental triumph. Punishing the sound environmental use of fly ash, especially as a substitute for cement in concrete, is the wrong direction.

Fly Ash Looms as the "New Asbestos"

(Engineering News Record 4-7-2010) Concrete groups are on tenterhooks, waiting for the U.S. Environmental Protection Agency to publish a proposed rule that aims to designate fly ash and other coal-combustion by-products as hazardous waste. The concrete sector is concerned even about the ramifications of a “hybrid” rule that would allow beneficial uses of CCBs to continue.Major among these beneficial uses is fly ash in concrete. The ingredient, a partial replacement for portland cement, is known to increase concrete’s constructibility, durability and sustainability.
