The Department of Environmental Quality’s (DEQ) risk classification for North Carolina’s coal ash pits puts the health of residents who live downstream from the Cliffside coal ash impoundments, including those who live in Shelby and Gaffney, SC, at risk from contaminated drinking water.
The DEQ issued its Coal Combustion Residual Impoundment Risk Classifications report on the afternoon of Friday, January 29. The DEQ has classified two of the Cliffside coal ash pits as low and one as “low/intermediate” priority despite testing that shows high levels of arsenic, chromium, cobalt, hexavalent chromium, thallium and vanadium contaminating groundwater and flowing into the Broad River. A classification of high or even intermediate priority would require Duke Energy excavate the sites, while a low rating means coal ash will be left on the banks of the Broad river to pollute a public drinking water source in perpetuity.
David Caldwell, coordinator of the Broad River Alliance — a Waterkeeper Alliance Affiliate, states:
“We know there are toxic chemicals in these ash ponds, and we know that they’re spilling into the Broad River and seeping into our drinking water. On every criteria set out by legislature in the Coal Ash Management Act, these three sites deserve a failing grade. If we don’t push the DEQ, all they’ll require for these pits it that they be covered and left in place to continue polluting our water in perpetuity. We are asking DEQ to show us the same respect given to 13 other communities across NC, and have the ash ponds permanently removed.”
DEQ is required to rate the ponds high, intermediate or low based on three criteria: the impact to surface water, the impact to groundwater and dam safety. According to the DEQ’s own Corrective Action Plan for the Cliffside Steam Station Ash Basin (November 16, 2015) all three of the Cliffside sites deserve a failing grade.
- Pollution of Groundwater:
All three Cliffside coal ash ponds pollute the groundwater with high levels of toxic metals, including arsenic at over 468 times the state’s safety standard, vanadium at 690 times the standard, hexavalent chromium at 185 times the standard and cobalt at 119 times the standard. The polluted groundwater from all three pits flows into the Broad River and Suck Creek, which are drinking water sources for Shelby NC, Gaffney SC and other downstream municipalities.
- Pollution of Surface Water:
All three coal ash ponds pollute the Broad River and Suck Creek with 28 illegal discharges that dump millions of gallons of toxic heavy metals each day, including chromium at 51 times the limit, arsenic at 37 times the state’s safety, and cobalt at 19 times the state’s safety standard.
- Deficiency of Dam Infrastructure:
DEQ has rated the dams as low priority despite the fact that the three Cliffside coal ash ponds received 5 notices of deficiency for dam structural integrity in 2014. DEQ has justified its ratings based on the outcome of future renovations to the dams’ structure that have yet to be completed. The Coal Ash Management Act was designed to rate the dams on their current risk and currently all the dams have received recent notice of deficiencies for many of the same problems that caused the Dan River spill.
The heavy metals and toxic chemicals seeping from the Cliffside coal ash pits are present at levels that are harmful to humans and wildlife. Arsenic poisoning can lead to heart disease, cancer, stroke, chronic lower respiratory diseases and diabetes. Cobalt has been linked to cardiovascular disease, gastrointestinal disorders, blood poisoning, liver injury and thyroid problems. Chromium is a carcinogen and hexavalent chromium was the subject of the movie Erin Brockovich, which was based on the true story of groundwater contamination in Hinkley, California by Pacific Gas Electric Company.
