Section D: Summary of Finding/Comments(Attach additional sheets of narra We and checklists as necessary)
Duke Energy's Cedar Cliff Hydroelectric Powerhouse consists of a pinstock to the powerhouse, powerhouse
generation equipment, central powerhouse sump and tailrace. The tailrace discharges to the Tuckaseegee
River. The plant has permitted discharges of generator thrust bearing cooling water and central powerhouse
sump.
Mr. Keith Haynes and Mr. Larry Frost perforated the inspection. The facility appeared to be well maintained
and operating properly. 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 the pinstock before it enters the turbine,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)treasure for this type industry (examples discussed were; CFS and MGD, 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.

Cedar Cliff Hydroelectric Plant

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.
If all discharge has ceased at your facility and you wish to rescind this CoC [or if you have other
questions], contact me at the telephone number or e-mail address listed below.
Sincerely,
Charles H.Weaver,Jr.

Dear Permittee:
Your facility is currently covered for wastewater discharge under General Permit NCG500000. This permit expires
on July 31,2002. Division of Water Quality(DWQ)staff is in the process of rewriting this permit with a
scheduled reissue in the summer of 2002. Once the permit is reissued,your facility would be eligible for continued
coverage under the reissued permit.
In order to assure your continued coverage under the general permit,you must apply to the DWQ for renewal of
your permit coverage. To make this renewal process easier,we are informing you in advance that your permit
coverage will be expiring. Enclosed you will find a general permit coverage renewal application form. This.
will serve as your application for renewal of your permit coverage. The application must be completed and
returned with the required information by February 01,2002 in order to assure continued coverage under the
general permit.There is no renewal fee associated with this process. Your facility will be invoiced for the annual
permit fee at a later date.
Failure to request renewal within this time period may result in a civil assessment of at least$250.00. Larger
penalties may be assessed depending on the delinquency of the request Discharge of wastewater from your facility
without coverage under a valid wastewater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to$10,000 per day.
If the subject wastewater discharge to waters of the state has been terminated,please complete the enclosed
rescission request form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
If you have any questions regarding the permit coverage renewal procedures please contact the Asheville Regional
