RE: Advance Notification of Hydroelectric Unit Repairs
Lookout Shoals Development
Catawba-Wateree Hydro Project P-2232
Federal Energy Regulatory Commission Staff Request for Additional Documentation
Dear Secretary Bose:
On November 18, 2016, Duke Energy Carolinas, LLC (Duke Energy) submitted to the Federal
Energy Regulatory Commission (Commission) advance notification of required Maintenance of
the Normal Means of Providing Minimum Flow (Scheduled) under the Catawba-Wateree Project
license's Maintenance and Emergency (MEP) Condition B.1.
On November 29, 2016, Commission staff contacted Duke Energy to request additional agency
documentation regarding the upcoming repairs at the Lookout Shoals Development.
Specifically, Maintenance and Emergency Protocol Condition B.1 — Maintenance of the Normal
Meals of Providing Minimum Flow Release (Scheduled), item 3 states if Critical Flows cannot
be exceeded 100% of the time, then Duke Energy will work with resource agencies to monitor
impacts and replace species mortalities. In this case, instantaneous minimum flows will drop
below the 80 cfs Critical Flow for this development, but not less than approximately 53 cfs
(documented leakage) while the average daily flow of approximately 90 cfs will exceed the
Critical Flow release.
As of November 29, 2016, no agency had expressed the need for additional consultation,
monitoring, or mortality replacement in this matter, but Commission staff requested a
documented affirmation from resource agencies as to whether or not they agree with Duke
Energy's approach to this maintenance event, and with monitoring impacts and replacing
mortalities not being required. Duke Energy solicited resource agency feedback via e-mail
dated November 29, 2016 and received responses representing all resource agency contacts
(see Attachment A) by November 30, 2016. The latest agency responses do not require Duke
Energy to monitor for impacts or to replace mortalities. The North Carolina Division of Water
Resources asked Duke Energy to monitor leakage flows to assure these flows do not fail below
53 cfs. Duke Energy cannot control leakage flows, but will monitor all flow releases.
Please direct questions to Mark Oakley at [phone] ([e-mail]).

The NC Wildlife Resources Commission is fine with Duke Energy's approach and doesn't see the need for monitoring
impacts.

regarding the upcoming repairs at the Lookout Shoals Development. Specifically, Maintenance and Emergency Protocol

Condition B.1— Maintenance of the Normal Meals of Providing Minimum Flow Release (Scheduled), item 3 states if
Critical Flows cannot be exceeded 100% of the time, then Duke Energy will work with resource agencies to monitor
impacts and replace species mortalities. In this case, instantaneous minimum flows will drop below the 80 cfs Critical

To -date no agency has expressed the need for additional consultation, monitoring, or mortality replacement in this
matter, but the FERC has requested a documented affirmation from resource agencies as to whether or not they agree
with Duke Energy's approach to this maintenance event, and monitoring impacts and replacing mortalities are not

With apologies for the short deadline, please send me your response as soon as possible, but no later than Wednesday
noon. I'll then file your responses with the FERC so they can issue an approval letter before the scheduled start of unit
repairs on Monday Dec 5.
Thank you. Please contact me if there ae further questions.

Good afternoon Mark.
As you requested, the USFWS has reviewed the information presented by Duke Energy regarding the upcoming
repairs at the Lookout Shoals Development. The USFWS is in agreement with the project as proposed by Duke
Energy and we do not foresee the need for additional monitoring for impacts at the site during the proposed
maintenance activities.
If you have questions or if I can be of assistance, please do not hesitate to contact me.
Thanks,

Thank you, Fred.
I'd like to clarify if your response also reflects feedback from Karen Higgins. If so, then your response will fulfill feedback
from all resource agency contacts.
Duke Energy will monitor all flow releases, including the leakage flow of approximately 53 cfs, but has to add we cannot
control the seepage flow and therefore cannot assure the flow does not drop below this level. Since the Catawba Basin
is in Low inflow Protocol stage 1 Duke Energy would prefer to not make large flow releases from the large units to
compensate for leakage flow excursions, which are anticipated to be small, if any.

Duke Energy will space the pulse flows at equal time intervals to distribute the flow releases throughout the day.

Mark,
The Division of Water Resource's response is as follows:
For the record, as reported in Duke Energy's submittal to FERC on 11-2-2016, the 53 cubic feet per second (cfs) is the
mean value based on ADCP measurements (N = 8, range = 19 to 80 cfs). Mean dam seepage is 5.0 cfs (N = 2, Range = 4.9
and 5.1 cfs). Duke should monitor the USGS gage to assure that the flow does not drop below 53 cfs, based on the
corresponding gage height of 9.25 feet. Although an average daily flow is not a suitable regime for establishing a
permanent Critical Flow, the mitigating factor is that this release schedule is planned for less than the month of
December and is higher than the instantaneous Critical Flow of 80 cfs. The two, 1 -hr pulse flows, as reported in the 11-
18-2016 FERC submittal, should be equally spaced if possible to equitably distribute the daily average flow. This should
resolve DWR's concerns.
Thank you for the opportunity to respond.
