Subject: NPDES Permit Issuance
Permit No. NC0003573
Fayetteville Works
Bladen County
Division personnel have reviewed and approved your application for renewal of the
subject permit.. Accordingly, we are forwarding the attached NPDES discharge permit.
This permit 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 May 9, 1994 (or as subsequently amended).
The following modifications from your draft permit are included in the final permit:
• Sampling frequency for conductivity was corrected to weekly.
• The waiver for instream sampling that was inadvertently omitted in the draft
permit is included in the footnotes for Outfall 002.
• Monthly monitoring for PFOA was added to outfall 002 to gather effluent and
instream data for this parameter.
If any parts, measurement frequencies or sampling requirements contained in this
permit 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
Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is
made, this decision shall be fmal and binding.
Please note that this permit is not transferable except after notice to the Division. The
Division may require modification or revocation and reissuance of the permit. This
permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Water Quality or permits required by the Division of Land
Resources, the Coastal Area Management Act or any .other Federal or Local
governmental permit that maybe required.

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
Permit NC0003573
Beginning on the effective date of this permit and lasting through the expiration date, the Permittee is authorized
to discharge from Outfall 002 (boiler blowdown, once -through cooling water, and treated wastewater from
outfall 001) Such discharges shall be limited and monitored by the Permittee as specified below:
Notes:
1. Upstream shall be at the Permittee's river pump station; downstream shall be at the boat ramp approximately
4500 feet downstream at Prospect Hall Landing.
As a participant in the Cape Fear River Basin Association, the instream monitoring requirements as stated
above are waived. Should your membership in the agreement be terminated, you shall notify the Division
immediately and the instream monitoring requirements specified in your permit shall be reinstated.
2. The temperature of the effluent shall be such as not to cause an increase in the temperature of the receiving
stream of more than 2.8°C and in no case cause the ambient water temperature to exceed 32°C.
3. Daily shall be defined as every day except Saturdays, Sundays, and legal holidays. Instream temperature
sampling shall be conducted weekly.
4. The samples for fluoride shall be taken downstream of the 001 discharge, unless or until, all neutralized
Nafion area streams are discharged entirely into the cooling water outfall, 002. Instream fluoride monitoring
shall be conducted monthly and shall coincide with effluent monitoring.
5. PFOA (Perfluorooctanoic acid) - The Cape Fear River water intake may be sampled for PFOA on a monthly
basis and reported as an upstream parameter in DWQ Form - MR -3.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN TRACE
AMOUNTS. '

A. (4) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) - OUTFALL 001
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 3.3%.
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 II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions. The tests will be performed during the months of February, May, August, and November. 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.
Ali 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 THP313 for the Chronic Value. Additionally, DWQ Form AT -3 (original) is to be sent to the
following address:
Attention: Environmental Sciences Section
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 Section 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 an
d 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 monitori
ng 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 Section at
the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitori
ng is required, monitoring will be
required during the following month.
Should any test data from this monitori
ng 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 organ
ism
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.
Permit NC0003573
A. (5) RE -OPENER CONDITION
This permit shall be modified, or revoked and reissued to incorporate additional toxicity limitations and
monitoring requirements in the event toxicity testing or other studies conducted on the effluent or receiving
stream indicate that detrimental effects may be expected in the receiving stream as a result of this discharge.
A. (6) BIOCIDE CONDITION
The permittee shall not use any biocide except those approved in conjunction with the permit application. The
permittee shall notify the Director in writing not later than ninety (90) days prior to instituting use of any
additional biocide used in cooling systems which may be toxic to aquatic life other than those previously reported
to the Division of Water Quality. Such notification shall include completion of Biocide Worksheet Form 101 and a
map locating the discharge point and receiving stream.
