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)
Dear Secretary Bose:
On April 29, 2016, Duke Energy Carolinas, LLC (Duke Energy) requested an extension of time
to file both the Flow and Water Quality Implementation Plan (FWQIP) and the Water Quality
Monitoring Plan (WQMP) as 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. The Commission granted this request on May 13, 2016. As
explained below, Duke Energy respectfully requests an additional extension of time to file both
of these plans.
As Duke Energy summarized on April 29, 2016, several stages have had to be completed
sequentially in order to submit the subject plans to the Commission. These stages and their time
frames in 2016 follows.
February 28 — August 6: Catawba-Wateree Comprehensive Relicensing Agreement
(CRA) Parties approved five CRA revisions. This time period included a 30 -day period
for Parties to review draft revisions, additional Party outreach, finalizing the revisions,
and a 60 -day period for Parties to vote on their approval of final revisions. During this
time Duke Energy also prepared draft water quality certification (WQC) amendment
applications. In order to save time, this activity was initiated before CRA Party approval
was received on the anticipation all CRA modifications would be approved.
July 15 - August 25 — Duke Energy submitted draft WQC amendment applications for
agency consultation and received and responded to all agency comments.
August 25 - September 9: WQC amendment applications were finalized and filed with
both states.
September 9, 2016 — Present: State WQC processes have been underway including public
notice and comment periods and Duke Energy responding to one additional information
request.

The intent of this plan has been to process several changes to both the CRA and the Project
license as a consolidated package of changes for submittal to the North Carolina and South
Carolina WQC agencies for approval and thereafter submit to the Commission as part of a
license amendment application. The subject FWQIP and WQMP have been revised since being
approved in each state's original WQC, so these revised plans must be approved via amended
WQCs before requesting a license amendment. Attachment A depicts graphically the changes
considered at each stage of this plan and how changes proceed through successive stages of this
plan to obtain necessary approvals.
On November 30, 2016, Duke Energy contacted both the NC Department of Environmental
Quality and the SC Department of Health and Environmental Control to request the status of
each state's WQC amendment process. While it would be inappropriate for Duke Energy to
speak for these agencies, based on feedback received, these processes are not complete and Duke
Energy does not expect these processes to be completed in time to prepare and file a license
amendment application by December 31, 2016.
For the preceding reasons, Duke Energy respectfully requests an extension of time from
December 31, 2016, to April 1, 2017 to file both the revised FWQIP and WQMP as part of a
comprehensive license amendment application.
Please contact Mark Oakley at ([e-mail] if you have questions or
require additional information.
Sincerely,
Tly
