You are receiving this notice because you currently operate a fish farm or fish packing / rinsing facility
covered under the subject General Permit. NCG530000 will expire on July 31, 2007. Federal (40 CFR 122.41)
and North Carolina (15A NCAC 2H.0105(e)) regulations require that permit renewal applications be filed at
least 180 days prior to expiration of the current permit. To satisfy this requirement, the Division must receive
a renewal request postmarked no later than February 1, 2007.
The Certificate of Coverage (CoC) specific to your property was last issued on August 1, 2002. The
Division needs information from you to determine if coverage under NCG550000 is still necessary.
➢ If your property still has a wastewater system like the ones described in the enclosed Technical
Bulletin, you must renew the subject CoC.
➢ If you are not sure what type of system your property has, contact Larry Frost in the NC DENR
Asheville Regional Office at [phone]. That person [or other staff members] can help you
determine if you should renew your CoC.
If you know that your facility no longer discharges to a waterbody, contact me at the address or
phone number listed below to request rescission of the CoC.
The attached application form shows the information the Division has on file for your property. Please
verify that the provided information is correct, or make corrections on the form. Complete the additional
questions, then sign and date the form. The completed form should be submitted to the address listed below
the signature block.
If you have any questions concerning this matter, please contact me at the telephone number or e-mail
address listed below. (If it is difficult to reach me, please be aware that your facility is one of over 1400 that I
am contacting regarding the renewal of several General Permits.) Thanks f your attention to this matter.

Subject: NPDES Wastewater Permit Coverage Renewal
Tusquittee Trout Ranch Incorporated
COC Number NCG530130
Clay County
Dear Permittee:
Your facility is currently covered for wastewater discharge under General Permit NCG530000. 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
Office at 828-251-6208 or Aisha Lau of the Central Office Stormwater Unit at [phone], ext. 578

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Duke Energy's Mission Hydroelectric Powerhouse consists of a dam, powerhouse generation equipment,
central powerhouse sump and tailrace. The tailrace discharges to the Hiwassee River, The plant has
permitted discharges of generator thrust bearing cooling water and central powerhouse sump.
Mr. Keith Haynes and Mr. tarry Frost performed the inspection. The facility appeared to be wel
and operating properly. There were no Lin -permitted discharges noted during the inspection. l maintained
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
upstrearn sampling site should be the darn inlet to the powerhouse, the effluent site from the tailrace and the
downstream tream at a predetermined (sate access) site downstream of the tailrace discharge point to the stream.
Possible sites were discussed during the inspection; it is recommended that those 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 notrequired to be submitted to the State, the inspectors recommend that Duke Energy
use common units of measure for this type industry (examples discussed were; DFS 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 Fitts for his assistance during the inspection,

Subject: NPDES Permit NCG500000 renewal
Certificate of Coverage (CoC) NCG500128
Mission Hydroelectric Plant
Clay 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.
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,
VU07-

COC Number NCG500128

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
Office at 828-251-6208 or Delonda Alexander of the Central Office Stormwater Unit at [phone], ext. 584
