Summary of Catawba-Wateree Comprehensive Relicensing Agreement
(CRA) Modifications and License Amendments
Catawba-Wateree River Basin Advisory Commission Briefing — October 26, 2016
Summary of NC and SC Water Quality Certification (WQC) Amendments
• Draft amendment application issued for NC and SC agency consultation July 15, 2016
• Consultation comments returned by August 25, 2016
• Amendment applications filed in NC and SC on September 9, 2016
• SC public comment process runs from September 30, 2016 through October 30, 2016
• Public hearings not expected
WQC amendments are necessary due to the changes listed below. These changes affect
certain sections and appendices of the Catawba-Wateree Comprehensive Relicensing
Agreement (CRA) dated December 22, 2006 (Rev 1) which are also incorporated by reference
as conditions of the original WQCs.
1. CRA Parties have found it to be beneficial to improve regional drought resiliency by
raising reservoir summer target elevations on Lakes James, Norman, and Wylie
by an additional 6 inches from May 1 — October 1 and to make a public safety
improvement by modifying the 6,000 cubic feet per second (cfs) recreation flow
release from the Wylie Development to 3,000 cfs.
2. Duke Energy voluntarily initiated revisions to update the Low Inflow Protocol (LIP)
and the Maintenance and Emergency Protocol (MEP) in accordance with the CRA
based on experience gained during voluntary implementation of these protocols since
2006. The revisions to the LIP are also consistent with recommendations from the
Water Supply Master Plan prepared in 2014-2015 by the Catawba-Wateree Water
Management Group.
3. The license issued for the Catawba-Wateree Hydroelectric Project on November 25,
2015 requires Duke Energy to file both a Water Quality Monitoring Plan (WQMP) and
a Flow and Water Quality Implementation Plan (FWQIP). These plans are presented in
CRA Appendices F and L respectively. During the time since these CRA provisions
were developed in 2006, some of these provisions, their status and implementation
schedule have changed.
