Arsenic
And Other Toxins Leaking Into Dan River From North Carolina Coal Ash
Dump
20
February, 2014
RALEIGH,
N.C. (AP) — North Carolina officials said Tuesday that groundwater
containing unsafe levels of arsenic apparently leaching from a Duke
Energy coal ash dump is still pouring into the Dan River, which is
already contaminated from a massive Feb. 2 spill.
The
state Department of Environment and Natural Resources ordered Duke to
stop the flow of contaminated water coming out a pipe that runs under
a huge coal ash dump at its Eden power plant. A nearby pipe at the
same dump collapsed without warning two weeks ago, coating the bottom
of the Dan River with toxic ash as far as 70 miles downstream.
State
regulators expressed concern five days ago that the second pipe could
fail, triggering a new spill. The water coming out of that pipe
contains poisonous arsenic at 14 times the level considered safe for
human contact, according to test results released by the state on
Tuesday.
"We
are ordering Duke Energy to eliminate this unauthorized discharge
immediately," said Tom Reeder, director of the N.C. Division of
Water Resources.
Video
taken last week by a robot sent inside the 36-inch-wide concrete pipe
showed wide gaps between seams through which groundwater is gushing
in, likely from the toxic dump above.
Tests
on water from the pipe before it goes under the dump showed none of
the dangerous contamination detected at the other end. The concrete
inside the pipe is heavily stained around the numerous leaks,
suggesting the contamination is likely not new.
A
state inspector received the video recorded by Duke during a Feb. 11
visit to the site, but did not review it until Thursday. On Friday
night, the state agency went public with concerns about the pipe's
structural integrity.
Duke
spokeswoman Paige Sheehan quickly issued a statement, downplaying the
risk.
"After
reviewing the videotape, we determined that no immediate action was
necessary," it said.
In
the wake of the initial spill, public health officials issued
advisories telling people to avoid contact with the river water and
not eat the fish.
Authorities
said public drinking water in Danville, Va., and other communities
downstream of the Duke plant remain safe. Heavy metals detected in
the river at levels exceeding state and federal safety standards —
including arsenic, lead and selenium — are being successfully
filtered out of water drawn from the river at municipal treatment
plants, they said.
The
U.S. Fish and Wildlife Service said Tuesday a massive pile of coal
ash about 75 feet long and as much as 5 feet deep has been detected
in the river by the site of the Feb. 2 spill. Deposits varying from 5
inches deep to less than 1 inch coated the river bottom across the
state line into Virginia and to Kerr Lake, a major reservoir.
Federal
authorities expressed concern for what long-term effect the
contaminants will have on fish, mussels and other aquatic life.
"The
deposits vary with the river characteristics, but the short- and
long-term physical and chemical impacts from the ash will need to be
investigated more thoroughly, especially with regard to mussels and
fish associated with the stream bottom and wildlife that feed on
benthic invertebrates," said Tom Augspurger, a contaminants
specialist at the federal wildlife agency.
Benthic
invertebrates are small animals that live in the sediments of rivers
and lakes, such as clams, worms and crustaceans.
The
Dan River system in North Carolina and Virginia is home to two
federally listed endangered species, the Roanoke logperch fish and
the James spinymussel. The river also has another freshwater mussel,
the green floater, which is currently being evaluated for protection
under the U.S. Endangered Species Act.
Officials
said the coal ash is burying aquatic animals and their food. The ash,
created when coal is burned to generate electricity, could also clog
gill tissues in fish and mussels. The agency said public reports of
dead aquatic turtles at two state parks in Virginia had not yet been
verified by federal biologists.
The
U.S. Environmental Protection Agency has warned that increased flow
in the river resulting from last week's snowfall and rain threatens
to wash the toxic ash even further downstream. The Dan flows back
across into North Carolina before emptying into the Albemarle Sound.
Meanwhile,
Duke Energy announced Tuesday that its fourth-quarter profits jumped
58 percent after officials in North Carolina and other states
approved hikes in the rates customers pay for electricity. The
company had revenues of $24.6 billion for 2013.
George
Everett, Duke's director of environmental and legislative affairs,
told state legislators this week that the company is sorry for the
spill and will be accountable.
Any
costs incurred because of the cleanup will likely be passed on to
ratepayers, not shareholders, he said.
"We
have paid absolutely no attention to costs, to this point,"
Everett said, responding to a lawmaker's question about who will pay.
"We're focused on stopping the discharge and initiating the
remediation of the river. But when costs do come into play, when
we've had a chance to determine what those costs are, it's usually
our customers who pay our costs of operation."
It
would be up to the N.C. Utilities Commission to approve any new rate
hikes for Duke. Members of that board are appointed by Gov. Pat
McCrory, who worked at Duke for 28 years.
