CHARLOTTE — Charlotte Douglas International Airport says it doesn't want coal ash from a Duke Energy power plant buried under a planned new runway or other airport infrastructure.

The Charlotte Observer reports Interim Aviation Director Brent Cagle said there's uncertainty about how coal ash would work as fill material under a runway. He said the coal ash would be subjected to the pounding of hundreds of jets a day. Cagle said the concerns are too great to warrant using the coal ash.

The decision creates additional uncertainty about where millions of tons of coal ash in unlined pits near Charlotte will ultimately go. Duke Energy has been under pressure to clean up its coal ash ponds since a Feb. 2 spill sent thousands of tons of sludge into the Dan River.
