Request for Certification Rescindment
DWQ Project #: 20080915, Version 2 DENR • WATER QUALITY
WETLANDS AND STORkMATER BRANCH
Dear Ms. Sullins:
Duke Energy Carolinas, LLC's, (Duke Energy) is submitting this request to rescind the
North Carolina Division of Water Quality 401 Water Quality Certification (DWQ Project
#: 20080915, Version 2), dated October 12, 2010. This request to rescind the
401 Certification is due to the inadvertent combining of two separate Duke Energy
projects associated with the Bridgewater Development under one project number. The
projects in question are the Linville Dam Embankment Seismic Stability (ESSI) Project
and the Catawba-Wateree Hydroelectric Project (relicensing of hydroelectric dams).
The two projects are both in the Federal Energy Regulatory Commission (FERC)
Catawba-Wateree Hydroelectric Project #2232 but are completely separate projects.
The Linville Dam ESSI Project is being constructed as part of a nationwide effort to
increase the safety of dams during potentially catastrophic earthquake events as
mandated by the FERC. The Catawba-Wateree Hydroelectric Project (DWQ Project #:
20080915) is associated with the relicensing of hydroelectric dams at the Bridgewater,
Rhodhiss, Oxford, Lookout Shoals, Cowans Ford, Mountain Island, and Wylie
Developments.
To avoid any potential confusion, Duke Energy respectfully requests that the Division of
Water Quality (DWQ) create a new project number for the Linville Dam ESSI Project
and provide its re-approval of the 401 Water Quality Certification.
www.duke-energy.com
In addition, Duke Energy also requests that the 401 Certification issued on
November 14, 2008, (DWQ Project #: 20080915) for the Catawba-Wateree
Hydroelectric Project remain valid as stated in the November 14, 2008, approval.
Thank you so much for your time and effort put into this request. Should you have any
questions or comments regarding this letter, please feel free to call me at (828) 391-
6754 or Mark Oakley at [phone].
Sincerely,
Jonathan R. Wise
Project Director
