Dear Mr. Ogburn:
Based on an agreement between the State of North Carolina and the Environmental Protection Agency.
this permit is being re -opened to require a weekly average limit for ammonia. After calculating allowable
concentrations and analyzing past ammonia data, the Division has set this limit at three times your
monthly average concentration (not to exceed 35 mg/L).
Enclosed please find the modified permit. This permit modification is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between
North Carolina and the U. S. Environmental Protection Agency dated December 6, 1983.
Please note that effluent monitoring for conductivity was erroneously added to the permit issued to you
on June 14, 2002 and has been deleted from this permit. Please refer to A.(1.) to review this change.
If any parts, measurement frequencies or sampling requirements contained in this permit modification
are unacceptable to you. you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition.
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mall Service Center, Raleigh, North Carolina 27699-6714). Unless such
demand is made, this decision shall be final and binding.
Please take notice that this permit is not transferable. Part [I. E.4. addresses the requirements to be
followed in case of change in ownership or control of this discharge. This permit does not affect the legal
requirement to obtain other permits which may be required by the Division of Water Quality or permits
required by the Division of Land Resources. Coastal Area Management Act or any other Federal or Local
government permit that may be required.

SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (2) PROVISIONAL WAIVER OF INSTREAM MONITORING REQUIREMENTS
Instream monitoring requirements in this NPDES permit shall be provisionally waived so long as
the Permittee remains a member of the Upper Cape Fear River Basin Association and the
Association continues to function as approved by the Division and Environmental Management
Commission. If the Permittee does not participate in the Association or if the Association ceases
to function, the instream monitoring requirements in this permit become. effective immediately;
and the Division may reopen this permit by administrative letter to establish additional instream
monitoring requirements, it deems necessary to adequately characterize the effects of the
discharges on water quality in the receiving stream.
A (3). CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures
outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised
February 1998, or subsequent versions or "North Carolina Phase H Chronic Whole Effluent
Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be
performed during the months of March, June, September, and December. Effluent sampling for
this testing shall be performed at the NPDES permitted final effluent discharge below all
treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or Chv
below the permit limit, then multiple -concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean
of the highest concentration having no detectable impairment of reproduction or survival and the
lowest concentration that does have a detectable impairment of reproduction or survival. The
definition of "detectable impairment," collection methods, exposure regimes, and further

statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and TB P3B for the Chronic Value. Additionally,
DWQ Form AT-3 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch
no later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements
and all concentration/response data, and be certified by laboratory supervisor and ORC or
approved designate signature. Total residual chlorine of the effluent toxicity sample must be
measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity
monitoring is required, the permittee will complete the information located at the top of the
aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county,
and the month/year of the report with the notation of "No Flow" in the comment area of the
form. The report shall be submitted to the Environmental Sciences Branch at the address cited
above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be
re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival, minimum control organism reproduction, and appropriate
environmental controls, shall constitute an invalid test and will require immediate follow-up
testing to be completed no later than the last day of the month following the month of the initial
monitoring.

Per our telephone conversation, I have attached the correct limits pages for
NC0028118 and NC0023876 for your review. I will await your comments on these two
permits.
Also, there were three permits (NC0020184, NC0025241 and ft0026123),in which
I erroneously added summer AND winter limits. To date, I have not received any
comments from the permit holders or from the public regarding the modifications. As
such, at the end of the comment period (assuming no comments are received), I will
issue the permits as drafted. If comments are received, they will be addressed on an
individual basis.
Also, please note that ONE permit modification was not completed with the last batch
of modifications (NC0021474 - City of Mebane). However, this one will be modified
and sent to public notice on December 11, 2002.
Please let me know if you have questions or concerns.
Thanks again for your patience.

Christie,
This email summarizes our phone conversation regarding the permit renewals for
Asheboro (NC0026123) and High Point Eastside (NC0024210).
ASHEBORO TNC0026123f��
1) Effluent conductivity monitoring as not r quire m the previous NPDES permit
(1996-2001). It was required in the permit issued in July 2002. I must have missed it
when I reviewed the draft for the 2002 permit renewal. I don't not see a need for
effluent conductivity monitoring.
HIGH POINT EASTSIDE (NC0024210)
1) Footnote #3 needs to be removed from the effluent limits page for "expansion above
16.0 MGD".
2) Are the dual limits for total nitrogen and total phosphorous (mg/1 and lbs/day)
equivalent based on design flow of 26.0 MGD? If so, is there a specific reason for dual
limits? Which form will the facility be required to report, mg/1 or lbs/day?
Other than those items mentioned above, the permits appear to be ready for renewal.
If I discover any further issues, I'll forward them ASAP. Thanks for your assistance
with these.
Have a great dayl

Concerning NCO026441: I noticed sections A(2) and A(3) were -not attached

Concerning NCO030716: IWC's are not calculated consistently with
permitted flows. I believe the problem lies with the 7Q 10. Our data
base has it listed at 184 and the permit has it at 170. Can you review
the calculations and forward the correct 7Q 10 for our records?
I have no comments with the other facilities at this time. Thanks for
allowing us to participate in the review process.

3 The daily average dissolved oxygen effluent concentration shall not be less than 6.0 mg/l.
4 The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units.
5 Chronic Toxicity (Cedodaphnia) P/F at 90%; March, June, September and December; See Supplement to Effluent Limitations Page A (3).
There shall be no discharge of floating solids or visible foam in other than trace amounts.

Permit NCO026123
SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (2) PROVISIONAL WAIVER OF INSTREAM MONITORING REQUIREMENTS
Instream monitoring requirements in this NPDES permit shall be provisionally waived so long as
the Permittee remains a member of the Upper Cape Fear River Basin Association and the
Association continues to function as approved by the Division and Environmental Management
Commission. If the Permittee does not participate in the Association or if the Association ceases
to function, the instream monitoring requirements in this permit become effective immediately;
and the Division may reopen this permit by administrative letter to establish additional instream
monitoring requirements, it deems necessary to adequately characterize the effects of the
discharges on water quality in the receiving stream.
A (3). CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures
outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised
February 1998, or subsequent versions or "North Carolina Phase R Chronic Whole Effluent
Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be
performed during the months of March, June, September, and December. Effluent sampling for
this testing shall be performed at the NPDES permitted final effluent discharge below all
treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple -concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean
of the highest concentration having no detectable impairment of reproduction or survival and the
lowest concentration that does have a detectable impairment of reproduction or survival. The
definition of "detectable impairment," collection methods, exposure regimes, and further

s
J
statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and TIP3B for the Chronic Value. Additionally,
DWQ Form AT-3 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch
no later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements
and all concentration/response data, and be certified by laboratory supervisor and ORC or
approved designate signature. Total residual chlorine of the effluent toxicity sample must be
measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity
monitoring is required, the permittee will complete the information located at the top of the
aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county,
and the month/year of the report with the notation of "No Flow" in the comment area of the
form. The report shall be submitted to the Environmental Sciences Branch at the address cited
above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be
re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival, minimum control organism reproduction, and appropriate
environmental controls, shall constitute an invalid test and will require immediate follow-up
testing to be completed no later than the last day of the month following the month of the initial
monitoring.
