DEQ seeks additional information from Duke Energy

Friday, December 4, 2015 - 12:00 am

State environmental officials today asked Duke Energy to provide information missing from its Corrective Action Plans (CAPs) by Dec. 14.  The Coal Ash Management Act, or CAMA, requires DEQ to develop proposed classifications for all coal ash impoundments by Dec. 31. DEQ needs information contained in the CAPS, including data on the extent of groundwater contamination and its impact on private and public water supplies, to make informed decisions on how to classify each impoundment as low, intermediate or high-risk.

Duke Energy to date has submitted Comprehensive Site Assessments (CSAs) for all 14 coal ash facilities and 12 of 14 CAPs. State officials identified data gaps and deficiencies within the reports that could constrain DEQ’s efforts to implement the legislation. DEQ notified Duke of the deficiencies in its reports in the Impoundments Remediation Status Overview sent to the utility on Nov. 17.
 
Since CAMA became state law, DEQ staff has conducted weekly conference calls with the utility in an effort to adhere to the deadlines established by CAMA and identify and correct any deficiencies.  In addition, after the CSAs were submitted, staff from DEQ’s Division of Water Resources held meetings with the utility at DEQ’s regional offices to review the CSAs and identify areas of incompleteness. 
 
The area of greatest concern is the lack of groundwater data. The relationship of potential coal ash constituents detected in private and public water supply wells with respect to the coal ash impoundments has not been adequately evaluated at facilities where there are nearby receptor wells.
 
The information DEQ has requested is required to be included in the CAPs under CAMA.
