Subject:YOUR PROMPT ATTENTION REQUESTED - Advance notification of unit repairs at C-W
Project Lookout Shoals Hydro
Thank you for taking a moment to quickly reply to this note.

The Federal Energy Regulatory Commission has contacted me today 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 and seepage) while the average
daily flow of approximately 90 cfs will exceed the Critical Flow release.

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
required.

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.
