The Virginia Water Control Board on Thursday approved Dominion Virginia's Power's request to drain treated coal-ash water into Quantico Creek.
The board approved the permit in a 6-1 vote. The utility can now begin draining about 200 million gallons of treated water into the creek near the Possum Point power plant, which flows into the Potomac River.
The move comes after the Prince William Board of Supervisors asked for more time for public input and study on the proposal. Board members have indicated they may file suit to stop the process.
