Dear Ms. Hair:
In accordance with your request of November 28, 2012, the Division hereby transfers the subject
Certificates of Coverage (CoCs) to discharge under NCG500000. We apologize for the delay in
processing your request. While we did receive and process the previous change of ownership to
BAIS US Renewable Power Holdings, LLC, your firm's request was not received until you re-
submitted it to Mr. Kevin Bowden of our staff. This action is taken pursuant to the
requirements of North Carolina's General Statue 143-215.1 and the Memorandum of Agreement
between North Carolina and the US Environmental Protection Agency dated July 17, 2007 (or as
subsequently amended).
If any parts, measurement frequencies or sampling requirements contained in this General
Permit are unacceptable, you have the right to request an individual permit by submitting an
individual NPDES permit application. Unless such demand is made, this CoC shall be final and
binding.
Please note that each CoC is not transferable except after notice to the Division. The Division
may modify, or revoke and reissue this CoC. This issuance does not affect your legal obligations
to obtain any other Federal, State, or Local government permit that may be required.
If you have any questions concerning this permit, please contact Charles H. Weaver at telephone
number [phone] or via email ([e-mail]).

Attachment #3- Design data and treatment description
Santeetlah
The Santeetlah hydroelectric facility operates an air-cooled system. Stormwater and reservoir
water seepage into the Powerhouse is directed to a sump located in the Powerhouse
Basement. Treatment prior to discharge consists of oil and grease removal by floatation and
skimming.
All drains within the Santeetlah Facility (with the exception of the Oil Room) are routed to two
4,400 gallon sumps located in the basement of the Powerhouse. A transfer pump removes
storm water that collects in the downstream sump to the river. An automatic level control
system operates the pump. The upstream pump is a manual water jet pump. Any floating oils
and grease collected in the sump are removed by skimming and placed in a drum.
Transformer Banks Nos. 1 and 2 located on either side of the Powerhouse, and the OCB vessels
and station service transformers located behind the Powerhouse are diked and equipped with a
drainage system. This system has a manually operated gate valve that is kept closed except to
drain rainwater.
Process Water
Non -contact cooling water from Transformer Banks 1 and 2 and from the generator bearings is
discharged directly to the Little Tennessee River by-passing the basement sumps.

Discharge Frequency: Discharges from Outfall

RE: Discharge of Oily Water — Santeelah Outfall 003
NPDES Permit - NCG500050
Alcoa Inc. - Graham County
Dear Mr. Weaver:
Alcoa
Tennessee Operations
2300 North Wright Road
Alcoa, TN 37701-3141
USA
As reported to the Charles Weaver of the NCDENR Raleigh office on January 10, 2008
Alcoa Inc. experienced a release of an oily water discharge from Outfall 003 at the
Santeelah Powerhouse. The release caused a sheen to form on Cheoah Lake at the base
of the Powerhouse. Facility personnel became aware of the sheen at 8:00 AM on January
1 Oth and made the verbal report to the NCDENR on that date which satisfied the 24 hour
notification requirement. The release was also reported to the National Response Center
and Graham County Emergency Management on January 1 Oth.
The oil sheen was caused by a water line break that flooded the floor of the Santeelah
power house and washed residual oils off the floor. The oily water drained into a sump
located in the floor of the powerhouse. The oily water was pumped out through Outfall
003. It was estimated that less than 1 gallon of oil was released.
When the release was discovered on January loth, the sump was immediately shut off.
Members of the Santeelah Mechanical Crew responded by using boats to stretch booms
across the lake to contain the oil sheen. Once the sheen was captured, oil absorbent
booms were used to absorb the oil and remove it from the water's surface.
