ELG and Market Drivers Lead to Changes in Dry Ash Conversion Market

摘要

Utilities with coal fired assets are making and implement-ing their plans for compliance with the new Effluent Limitation Guidelines (ELG) and Coal Combustion Residual (CCR) rule. The final version of the ELG Rule bans the discharge of bottom ash transport water and the final version of the CCR rule puts new requirements on existing ash ponds. The combination of these two regulations will force many facilities with wet bottom ash handling to convert to dry ash handling. Planning for dry ash conversions for many facilities began when the original proposed CCR rule was released in 2010. For these early planning studies, the technology review assessments and recommendations for conversion were made based on a power generation market that is significantly different than what we are living with today.
