Tennessee Creek Hydroelectric Station
Certificate of Coverage NCG500123
Jackson County
Dear Permittee:
The Division has renewed the subject General Permit. We appreciate your patience during the
longer-than-expected renewal period. The Division hereby issues the updated version of Certificate of
Coverage (CoC) NCG500123 under General Permit NCG500000. It is issued pursuant to the requirements
of North Carolina General Statue 143-215.1 and the Memorandum of Agreement between North Carolina
and the US Environmental Protection agency dated October 15, 2007 [or as subsequently amended].
If any parts,measurement frequencies or sampling requirements contained in this General Permit
are unacceptable to you,you have the right to request an individual permit by submitting an individual
permit application. Unless such demand is made, the certificate of coverage shall be final and binding.
Please take notice that this Certificate of Coverage is not transferable except after notice to the
Division. The Division may require modification or revocation and reismance of the certificate of coverage.
Contact the Asheville Regional Office prior to any sale or transfer of the Permitted facility.
Regional Office staff will assist you in documenting the transfer of this Cod).
This permit does not affect the legal requirements to obtain any other State, Federal,or Local
governmental permit that may be required. If you have any questions concerning the requirements of the
General Permit,please contact Charles Weaver of the NPDES staff[919 807-6391 or

Mechanical cleaning operations which do not contribute any wastewater to the discharge are not limited by this permit.
Non-discharging cleaning operations may be conducted as often as necessary to ensure safety and proper facility
operation.
All non-contact cooling water sample locations shall provide representative samples of the discharge and require sampling
prior to discharge commingling with any other waters or substances, such as stormwater or surface water to enable
characterization of a pollutant of concern.
All samples collected should be from a representative discharge event,a measurable discharge event that results in an

There shall be no discharge of floating solids or visible foam(ether than trace amounts)in the effluent.
A(4) DISCHARGE ADDITIVE RESTRICTIONS
This permit does not authorize the discharge of water treatment or chemical additives(including but not limited to
chromium,zinc or copper)other than chlorine and approved de-chlorinating reagents without written approval from

SECTION B. SCHEDULE OF COMPLIANCE
i
I. The Perrmttee shall comply with Final Effluent Limitations by the effective date of the Certificate of Coverage. i
2. Pem»ttee shall at all times provide the operation and maintenance necessary to operate the existing facilities in accordance
with Standard Conditions for NPDES Permits Section C.2.of this permit.
'3. Permittee shall operate the existing facilities such that constituents and/or characteristics of the discharge qualify for
Certificate of Coverage under the General Permit in accordance with 15A NCAC 02H.0127.In accordance with NPDES
regulations at§ 122.45, allowing detection of a pollutant:Instances could arise where the combination of process and
non-process wastewaters result in dilution of a pollutant of concern such that it would not be detectable using approved
analytical methods.Internal monitoring would enable characterization of the pollutant before dilution with other
wastewaters.
4. The upstream location for the natural water temperature shall be interpreted as the influent to the penstock or other
appropriate location in the impounded waterbody. Effluent is the outflow from the powerhouse. The temperature
change between these two values is considered the heat added and judged for compliance with Note i of the permit
and 16A NCAC 2H.0211.6).
SECTION C. APPLICABILITY
This pernnt is applicable to the following types of discharges defined below:
1. Non-contact cooling water and open recirculation cooling water systems used in industrial processes for the sole
purpose of cooling machinery and other equipment. Non-contact cooling water is defined as water used for cooling
which does not come into direct contact with any raw material, intermediate product, waste product or finished
product. Contact cooling water is defined as cooling water that comes into contact with raw material,intermediate
product, finished product,byproduct or waste product. Open recirculating cooling water systems,continuously reuse
the cooling water which passes through the heat transfer equipment. Open recirculating cooling water system
discharges to a Water Supply water body may require an individual NPDES permit. Contact cooling water discharges
require an individual NPDES permit.
2. Condensate wastewater from atmospheric cooling systems..

Section D: Summary of Finding/Comments(Attach additional sheets Df narrativeand checklists as reccssary)
Duke Energy's Tennessee Creek Hydroelectric Powerhouse consists of a pinstock to the powerhouse,
Powerhouse generation equipment, central powerhouse sump and tailrace. The tailrace discharges to
Tennessee Creek. The plant has permitted discharges of generator thrust bearing cooling water and central
powerhouse sump.
Mr. Keith Haynes and Mr. Larry Frost performed the inspection. The facility was in the midst of an outage at
the time of the inspection, for maintenance. The Pinstock had recently been painted. There were no
un-permitted discharges noted during the inspection.
The purpose of the permit is to protect the receiving stream:therefore, the inspectors recommend that
Upstream, Effluent and Downstream sampling points be re-evaluated for this facility. The recommended
upstream sampling site should be upstream of the tailrace discharge, the effluent site from the tailrace and
the downstream at a predetermined (safe access) site downstream of the tailrace discharge point to the
stream. Possible sites were discussed during the inspection; it is recommended that these sites be
established by written policy.
Once the sampling sites are established, then the monitoring requirements and monitoring frequency for
each site should re-evaluated.
The proper reporting of flow from the powerhouse was discussed at length, during the inspection. Since
monitoring data is not required to be submitted to the State, the inspectors recommend that Duke Energy
use common units of measure for this type industry (examples discussed were; CFS and MOD, however
some other unit may be more appropriate)with regards to flow. If you should have any questions regarding
this issue please contact one of the inspectors.
Finally, a special word of thanks to Mr. Marcus Pitts for his assistance during the inspection.

Certificate of Coverage(CoC)NCG500123
Tennessee Creek Hydroelectric Plant
Jackson County
Dear Permittee:
The facility listed above is covered under NPDES General Permit NCG500000. NCG500000 expires
on July 31,2007. Federal(40 CFR 122.41)and North Carolina(15A NCAC 2H.0105(e))regulations require
that permit renewal applications must be filed at least 180 days prior to expiration of the.current permit. If
you have already mailed a renewal request,you may disregard this notice.
To satisfy this requirement,the Division must receive a renewal request postmarked no later than
February 1.2007. Failure to request renewal by this date may result in a civil penalty assessment. Larger
penalties may be assessed depending upon the delinquency of the request.This renewal notice is being sent
well in advance of the due date so that you have adequate time to prepare your application.
If any discharge previously covered under NCG500000 will occur after July 31,2007, the
CoC must be renewed. Discharge of wastewater without a valid permit would violate North Carolina
General Statute 143-215.1;unpermitted discharges of wastewater may be assessed civil penalties of up to
$25,000 per day.
I£all discharge has ceased at your facility and you wish to rescind this CoC for if you have other
questions],contact me at the telephone number or e-mail address listed below.
