Groundwater Assessment Plans for Duke Energy Coal Ash Facilities

Duke Energy Groundwater Assessment Plans for Coal-fired Power Stations

On Sept. 26, 2014, Duke Energy submitted draft plans for the assessment of groundwater at its 14 coal-fired power stations located in North Carolina. The Division of Water Resources staff reviewed the plans and sent letters with comments in November 2014. Duke Energy submitted revised plans on Dec. 30, 2014. The revised plans are posted below, followed by the original draft plans and the review letters.
The plans include proposed site assessment activities and a schedule for implementation, completion and submission of a comprehensive site assessment report for each of the facilities. The reports are required to provide information concerning:

For each approved plan, the utility will have 180 days to provide the state with a report describing all exceedances of groundwater quality standards associated with each coal ash storage pond including the information described above.
