Cumberland Times-NewsLUKE — Cleanup of 4,000 gallons of fly ash sludge that spilled into the Potomac River from a coal-burning power plant pipeline at the NewPage paper mill Sunday was completed within hours of the discovery of the leak, according to the NewPage public relations manager at Luke.
Maryland Department of the Environment spokeswoman Dawn Stoltzfus said the spill began at about 8 a.m. (Sunday) and continued until 6 a.m. Monday, when it was detected by NewPage employees during a daily inspection.

The sludge contained high concentrations of selenium, sulfate, arsenic, iron or manganese, prompting concerns of an environmental threat.
“Obviously, fly ash is not something that one wants in the water,” said Harley Speir, a fisheries biologist with the state Department of Natural Resources.
The shutdown of the damaged pipeline did not affect mill operations, Koontz said.

" The water quality of the Potomac River was not negatively impacted as a result of this small leak,” said Koontz.
That is exactly what they said in Tennessee. In another article about this Potomac spill from a Tennessee paper:
Clearly, this leak is minuscule compared to the billion-gallon deluge loosed from the TVA Kingston Plant in late-December, but we've seen from the emerging health problems among Kingston and Harriman residents that the ash's contents are nothing to sneeze at.
