Duke Energy Carolinas, LLC (Duke) is requesting an update to the NPDES Industrial Stormwater permit
application for the subject facility. This update is in addition to the renewal application submitted
September 29, 2014, previous update submitted July 15, 2017(via email), and the January 6, 2018 update.
Due to demolition activities located at the retired steam station, potential exists for damage to storm
drains from heavy equipment required to complete the work. We plan to plug SW Outfall 003 that
discharges directly to the Yadkin River. Flows from the SW003 drainage area will be directed to the
steam station basement sump. Additional stormwater protection measures will be implemented along the
Yadkin -side of the SW003 drainage area.
Should you have any questions regarding this letter or require additional information, please contact Ms.
Elizabeth Glenn at [phone] or at [e-mail].
