Duke Energy NPDES Wastewater Permitting

Subscribe to DWR's Public Notice and Announcements Listserv

In 2014, the N.C. Division of Water Resources directed Duke Energy to apply for National Pollutant Discharge Elimination System wastewater permit modifications or renewals to address issues at the company's 14 coal-fired electric plants. Documents relating to those permit modifications and renewals are posted below as they are received. Also included, where applicable, are plans and approvals for maintenance and other related activities.
