Vectren Corp. has finalized a plan to excavate and recycle coal ash from its 490-MW A.B. Brown plant in Posey County, Ind.
Vectren has signed a multiyear agreement for the excavation, conversion and recycling of up to 6 million tons of ponded coal ash, which will commence in 2021, according to an Aug. 14 news release.
The company has filed an application with the Indiana Utility Regulatory Commission to recover the costs associated with the coal ash removal and will soon begin constructing the infrastructure needed to transport the coal ash to the Ohio River, where it will be shipped off for recycling.
The CenterPoint Energy Inc. subsidiary is required to address the problem of ponded coal ash under the U.S. Environmental Protection Agency's Coal Combustion Residuals, or CCR, rule.
Material that can be used for "beneficial purposes" will be removed from the site, Lynnae Wilson, chief business officer of CenterPoint's Indiana electric utility business, said in the news release. Recycling the coal ash will cost customers less than other viable compliance options, according to Wilson.
The company has been shipping dry fly ash from the A.B. Brown project, as well as its F.B. Culley and Warrick coal-fired plants for use as a raw material in cement manufacturing since 2009, according to the statement.
