State Sen. Scott Surovell, D-Mount Vernon, represents homeowners living near Dominion Virginia Power’s Possum Point Power Station, which is in the process of disposing of millions of cubic yards of coal ash accumulated over the years. The coal combustion residue, he told the Senate Committee on Agriculture, Conservation & Natural Resources this afternoon, is a “booming, growing, ongoing problem.”
Dominion proposes consolidating the coal combustion residue from five ponds into one, which it will cap with a synthetic liner and monitor for leakage of potentially toxic heavy metals. But tests have found elevated levels of metals associated in the groundwater around the facility, and Surovell wants better protection for his constituents as well as other Virginians living near other coal ash sites. He has submitted a trio of bills that would require Virginia electric utilities to evaluate the options of coal ash recycling and/or disposing of the material into a synthetically lined landfills with leachate collectors.
Numerous coal ash ponds are scattered around Virginia, and Possum Point is furthest advanced in the regulatory process for closure. “This is new to everyone in the United States,” Surovell said, adding that he wants to make sure Dominion’s remedies don’t “blow up in a hundred years.”
In response William L. Murray, Dominion’s director of public policy, told the committee that Virginia’s Department for Environmental Quality (DEQ) is staffed with “experienced, apolitical regulators.” Surovell’s proposals, he said, amount to an alternative regulatory regime. “The fundamental premise is that there’s something wrong with our current regulatory structure. We respectfully disagree with that.”
Electric utilities have been storing coal ash for decades in impoundments, mixing the residue with water to keep the particles from blowing away. Responding to highly publicized spills of coal ash into Tennessee and North Carolina rivers, the Environmental Protection Agency (EPA) issued rules in late 2015 requiring electric companies to de-water the coal and safely dispose of the dry material. In Virginia, the DEQ is responsible for issuing waste-water and solid-waste permits tailored to the conditions of each site.
Dominion got off to a quick start but ran into opposition last year from environmental groups and local landowners, who said that its plans to dispose of the coal ash on-site would contaminate local water supplies. Tests around Possum Point have shown elevated levels of metals associated with coal ash, but a Duke University study suggested that trace metals in groundwater also can occur naturally. Although it is it unclear if the coal ash ponds were to blame, Dominion has offered to replace wells for seven homeowners with municipal water.
Electric companies in North Carolina, South Carolina and Georgia recycle, or plan to recycle, large percentages of their coal ash by selling it for use primarily as a cement additive to make concrete. At many sites, they will truck the ash to state-of-the-art landfills with synthetic liners, caps, and leachate collection systems. The Southern Environmental Law Center, which has handled litigation in Virginia and the other states, contends that Virginia should adopt the same practices.
There is considerable commercial demand for coal ash in Virginia, said Surovell. Indeed, there is so much demand that concrete manufacturers are importing the material from China and Poland. It makes no sense to import coal ash when there is plenty available at Dominion’s power stations, he said. Because the ash often requires an intermediate processing step known as beneficiation, recycling the residuals could create jobs in the commonwealth, he said.
One of Surovell’s bills, SB 1383, would require all Virginia electric utilities to “recycle as much of their stored coal ash as is imported into the Commonwealth each year, on a pro rata basis.” The bill would allow the utilities to recover its treatment costs from the taxpayers. Mimicking President Trump, Surovell told the committee, “I think this bill could be huuuge, and create tons and tons of jobs. … I want to make Virginia great again.”
A second bill, SB 1398, would require utilities to assess their closure options — closure in place, recycling, landfilling — and submit their evaluations for review by DEQ and the public. A third, SB 1399, would require “coal combustion by-products be removed for disposal in a permitted landfill meeting federal criteria and that the impoundment site be reclaimed in a manner consistent with federal mine reclamation standards.”
Murray said that Dominion already recycles about 700,000 tons of coal ash a year generated by its coal plants in Mecklenburg, Chesterfield and Virginia City, as well as one it co-owns with the Old Dominion Electric Cooperative in Clover. The material is used in concrete, wallboard and even bowling balls.
If concrete manufacturers are importing coal ash from overseas, why isn’t Dominion recycling all of its coal combustion residue? The circumstances vary from location to location. The problem at Possum Point, said Murray, is that the company would have to truck literally thousands of loads of the material along a residential road, creating issues with congestion, noise and diesel exhaust. It doesn’t take much imagination to think that Surovell’s constituents would object to that solution.
