Re: Duke Energy Carolinas, LLC
Catawba-Wateree Hydroelectric Project ® Project No. 2232
Request for Extensions of Time to file the Flow and Water Quality Implementation Plan
(FWQIP) and the Water Quality Monitoring Plan (WQMP)
ZZMEMEMMy=
Duke Energy Carolinas, LLC (Duke Energy) is required by the New License for the Catawba-
Wateree Hydroelectric Project (Project) issued by the Federal Energy Regulatory Commission
(FERC or Commission) on November 25, 2015 to file both a Flow and Water Quality
Implementation Plan (FWQEP) and a Water Quality Monitoring Plan (WQMP) by May 23, 2016
(180 days following issuance of the New License). For the reasons explained below, Duke
Energy respectfully requests an extension of time to file both of these plans.
New License Appendix E, Section A-2.0 (Flow Articles), Flow and Water Quality
Implementation Plan Article (A) requires:
Within 180 days following the issuance of this license, the Licensee must file with the
Coninfission, for approval, a Flow and Water Quality Implementation Plan (FWQIP) for
coA,rJetiny
at Project developments.
Current FWQIP requirements are contained in Comprehensive Relicensing Agreement (CRA)
Appendix L, which is included in both the North Carolina and South Carolina water quality
certifications (New License Appendices A and B) and are therefore requirements of the New
License.
New License Appendix E, Section A-5.0 (Water Quality Article), Water Quality Monitoring
Plan Article (A) requires:

Within 180 days follovving the issitance of this license, the Licensee must file with the
Coninfission, for appi-oval, a Water Quality Monitoring Plan (WQMP) to nlonitol-
compliance vith water quality requirements.
Current WQMP requirements are contained in CRA Appendix F, which is included in both the
NC and SC water quality certifications (New License Appendices A and B) and are therefore
requirements of the New License.
In the interim since these requirements were developed in 2006, the status of these requirements
has changed significantly. One driver behind these changes is current timelines for vendors to
design, fabricate, and deliver major components such as the new minimum flow units at the
Wylie and Wateree Developments are different than in 2006. A major additional D
driver is uke
Ener has alreadgi im(clemented ma�or items such as flow and water ,nts at the
Bridgewater Development (at both the Bridgewater Hydro Station and the Catawba Dam), the
Rhodhiss Development, and the Oxford Development as well as installing water quality monitors
at the Bridgewater, Lookout Shoals, and Mountain Island Developments. All these
implementations occurred substantially ahead of original schedules, which were years after
issuance of the New License. Duke Energy obtained Commission approval for early
implementation of these requirements, included in the CRA and Application for New License
and recommended in the Commission's July 2009 Final Environmental Impact Statement via
amendments to the Original License. These two drivers result in changes to the FWQIP and
WQMP schedules as originally included in both state water quality certifications and in the New
License.

Energy hopes to file these amendments simultaneously so these processes can proceed in parallel
and be completed later this year.
For the preceding reasons, Duke Energy respectfully requests an extension of time from May 23,
2016, to December 31, 2016 (provided water quality certification amendments are uncontested)
to file these plans. Duke Energy takes this opportunity to advise the Commission it is also
processing stakeholder -requested changes to the CRA, some of which will also require water
quality certification amendments and New License amendments. The requested extension date
reflects the coordinated schedules for the FWQIP, WQMP, and CRA changes concluding with a
consolidated New License amendment and implementation plan filing with the Commission.
