US: The American Coal Ash Association (ACAA) has criticised a proposed revision of coal ash regulations by the Environmental Protection Agency because it will restrict the recycling of coal ash.
"EPA's proposals related to the definition of coal ash beneficial use are the opposite of a regulatory roll-back," said Thomas H Adams, ACAA Executive Director ahead of a hearing with the EPA. "Without any damage cases or scientific analysis to justify its actions, the agency is seeking to impose burdensome new restrictions that will cause millions more tons of material to be disposed rather than be used in ways that safely conserve natural resources and energy."
Adams and the ACCA argue that previous EPA rules concluded that beneficial use of coal ash should be exempt from regulation and encouraged to contribute to sustainability. However, the ACCA has taken exception with a 2015 definition of beneficial use, which was intended to prevent ‘disposal activities masquerading as beneficial use.’ By expanding the scope of this definition the ACCA says that more coal ash will be landfilled instead of being recycled.
Coal is the fuel source for approximately one-third of electricity generation in the US and produces large volumes of solid coal combustion products - primarily ash and synthetic gypsum from emissions control devices. This family of diverse products is referred to as coal combustion residuals in a disposal setting and is often generically referred to as ‘coal ash.’
According to ACAA's most recent ‘Production and Use Survey,’ 64.4% of the coal ash produced during 2017 was recycled. By volume, 71.8Mt of coal combustion products were beneficially used in 2017 out of 111Mt that were produced. Coal ash production volume increased by 4% year-on-year from 2016.
