"The Trump administration is extending the life of giant pits of toxic coal sludge, a move critics say further risks contamination of nearby water sources.
The Environmental Protection Agency (EPA) late Wednesday announced it had finalized a new regulation for the more than 400 coal ash pits across the nation, where coal residue is mixed with liquid and stored in open air, often unlined ponds.
“Today’s action makes changes to the closure regulations for coal ash storage that enhance protections for public health while giving electric utilities enough time to retrofit or replace unlined impoundment ponds,” EPA Administrator Andrew Wheeler said in a release."
