Dominion Announces Plans to Close All Ash Ponds in Virginia
LCG, April 21, 2015--Dominion Virginia Power recently announced plans to close all of the ash ponds at its Virginia power stations in compliance with standards established by the Virginia Department of Environmental Quality (DEQ) and the Environmental Protection Agency's (EPA) new Coal Combustion Residuals (CCR) rules. Coal ash is the substance remaining after coal is burned to generate electricity. Under the EPA rules, fly ash has been determined to be a on-hazardous material.
"The EPA rules were just finalized, and we have been working on plans based on the proposed rule in order to be prepared," said Dominion's chief environmental officer and vice president of Corporate Compliance. "We are working with the Virginia Department of Environmental Quality and other state agencies to develop closure plans that are in compliance with the new rules."
Dominion will close the ash ponds at four locations in Virginia: Bremo Power Station, Chesapeake Energy Center, Chesterfield Power Station, and Possum Point Power Station. Coal is no longer used as a fuel at the Bremo, Chesapeake and Possum Point power stations. Dominion has closed or converted to cleaner fuel five coal-fired power stations serving Virginia over the past few years.
Dominion will initiate the actual ash pond closure work after the necessary permits are obtained. Dominion generally plans to drain the ponds and cover them with an impermeable liner that will be topped with 24 inches of soil. Either grass or sod will be planted on top of the soil. The specifics of the closure plan will be determined by DEQ. This closure method is expected to comply with the EPA's standards.
Earlier this month, Dominion announced its proposal to construct a 1,600-MW natural gas-fueled power station in Greensville County, Virginia. The facility is scheduled to commence operations in 2019.
