Dear Mr. Thomas:
In consideration of the Contentnea MSD and DuPont -Kinston s July 1, 2010, joint request for permit
modifications, the Division is forwarding herewith the revised NPDES permit for the DuPont - Kinston
WWTP. The enclosed pages should be inserted in your permit and the corresponding pages from the
previous version discarded. 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 October 15, 2007.
The Division received no public comments on the draft permit. The final permit includes the following
changes, as proposed in the September 15 draft:
• Total Nitrogen (TN) Limits. The facility's nitrogen discharge limit in Condition A.(1.) is decreased
from 30,493 lb/yr to 25,493 lb/yr, reflecting the transfer of 5,000 Ib/yr of discharge allocation (3,500
lb/yr as estuary allocation) from the Kinston Plant to the MSD. The new TN limit becomes effective
on January 1, 2011.
• TN Allocation. Condition A.(7.), Total Nitrogen Allocations, is also revised to reflect the transfer of
allocation.
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

A.(5.) CALCULATION OF TOTAL NITROGEN LOADS
(a.) The Permittee shall calculate monthly and annual TN Loads as follows:
(i.) Monthly TN Load (Ib/mo) = TN x TMF x 8.34
where:
TN = the average Total Nitrogen concentration (mg/L) of the composite
samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the month
(MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
(ii.) Annual TN Load (Ib/yr) = Sum of the 12 Monthly TN Loads for the calendar year
(b.) The Permittee shall report monthly Total Nitrogen results (mg/L and Ib/mo) in the discharge monitoring
report for that month and shall report each year's annual results (Ib/yr) in the December report for that year.
A.(6.) ANNUAL LIMITS FOR TOTAL NITROGEN
(a.) Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse River basin are
annual limits and are applied for the calendar year.
(b.) For any given calendar year, the Permittee shall be in compliance with the annual TN Load limit in this
Permit if:
(i.) the Permittee's annual TN Load is less than or equal to said limit, or
(ii.) the Permittee is a Co-Permittee Member of a compliance association.
(c.) The TN Load limit in this Permit (if any) may be modified as the result of allowable changes in the
Permittee's TN allocation.
(i.)

A.(8.) 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 9.9%.
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 January, April, July, and October. 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 THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
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 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 Section 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.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such monitoring
shall be included in the calculation and reporting of the data submitted on the DMR and all AT Forms submitted.
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.

A.(9.) BIOCIDES
The Permittee shall not use any biocides in its cooling systems except those approved by the Division of Water
Quality in conjunction with the permit application. The Permittee shall notify the Director in writing not later than
ninety (90) days prior to planned use of any additional biocide which may be toxic to aquatic life, other than those
previously reported to the Division. Such notification shall include submittal of a completed Biocide Worksheet
Form 101 and a map locating the discharge point and receiving stream.
A.(10.) INSTREAM MONITORING
Instream monitoring requirements in this NPDES permit shall be provisionally waived so long as the Permittee
remains a member of the Lower Neuse Basin Association and the Association continues to function as approved
by the Division and the 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.(11.) NON -DETECTION REPORTING AND DETERMINATION OF COMPLIANCE
When pursuant to this permit a pollutant analysis is conducted using an approved analytical protocol with the
appropriate minimum detection level and a result of "non -detectable" or "below quantitation limit" is obtained, the
Permittee shall record that result as reported. For the purpose of determining compliance with a permit limit for
the pollutant, the numerical value of that individual analytical result shall be zero.
A.(12.) PRODUCTION MODIFICATIONS
Should the facility's idle production become active, or if new production is added, and/or is resold during the
permit cycle, the permittee must submit to the Division:
1. proposed process description with impacts to each outfall
2. projected complete plant water balance schematic with impact to each ouffall
3. projected production information.
The required information must be provided 180 days prior to the production changes. A permit modification
application is required for any production changes to allow evaluation and calculation of modified permit limits.
During the next scheduled permit renewal the permittee is to include actual production data based on EPA
guidelines.

2. Stormwater Management Plan. The stormwater management plan shall contain a narrative description of
the materials management practices employed which control or minimize the exposure of significant
materials to stormwater, including structural and nonstructural measures. The stormwater management
plan, at a minimum, shall incorporate the following:
a. FeasibilityStudy. A review of the technical and economic feasibility of changing the methods of
operations and/or storage practices to eliminate or reduce exposure of materials and processes to
stormwater. Wherever practical, the permittee shall prevent exposure of all storage areas, material
handling operations, and manufacturing or fueling operations. In areas where elimination of
exposure is not practical, the stormwater management plan shall document the feasibility of diverting
the stormwater runoff away from areas of potential contamination.
b. Secondary Containment Requirements and Records. Secondary containment is required for: bulk
storage of liquid materials; storage in any amount of Section 313 of Title III of the Superfund
Amendments and Reauthorization Act (SARA) water priority chemicals; and storage in any amount of
hazardous substances, in order to prevent leaks and spills from contaminating stormwater runoff. A
table or summary of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to stormwater
conveyance systems, the connection shall be controlled by manually activated valves or other similar
devices (which shall be secured closed with a locking mechanism), and any stormwater that
accumulates in the containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by any material. Records
documenting the individual making the observation, the description of the accumulated stormwater,
and the date and time of the release shall be kept for a period of five years.
c. BMP Summary. A listing of site structural and non-structural Best Management Practices (BMP)
shall be provided. The installation and implementation of BMPs shall be based on the assessment of
the potential for sources to contribute significant quantities of pollutants to stormwater discharges
and data collected through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the selected site BMPs.
The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall incorporate an
assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel (or
the team) responsible for implementing the SPRP shall be identified in a written list incorporated into the
SPRP and signed and dated by each individual acknowledging their responsibilities for the plan. A
responsible person shall be on -site at all times during facility operations that have the potential to
contaminate stormwater runoff through spills or exposure of
Part I, Page 16 of 19

(Continued)
materials associated with the facility operations. The SPRP must be site stormwater specific. Therefore, an
oil Spill Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP, but may
not be sufficient to completely address the stormwater aspects of the SPRP. The common elements of the
SPCC with the SPRP may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and good
housekeeping program shall be developed. The program shall list all stormwater control systems,
stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial activity areas
(including material storage areas, material handling areas, disposal areas, process areas, loading and
unloading areas, and haul roads), all drainage features and structures, and existing structural BMPs. The
program shall establish schedules of inspections, maintenance, and housekeeping activities of stormwater
control systems, as well as facility equipment, facility areas, and facility systems that present a potential for
stormwater exposure or stormwater pollution. Inspection of material handling areas and regular cleaning
schedules of these areas shall be incorporated into the program. Timely compliance with the established
schedules for inspections, maintenance, and housekeeping shall be recorded in writing and maintained in
the SPPP.
5. Employee Training. Training programs shall be developed and training provided at a minimum on an annual
basis for facility personnel with responsibilities for: spill response and cleanup, preventative maintenance
activities, and for any of the facility's operations that have the potential to contaminate stormwater runoff.
Facility personnel (or team) responsible for implementing the training shall be identified, and their annual
training shall be documented by the signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific position(s)
responsible for the overall coordination, development, implementation, and revision to the Plan.
Responsibilities for all components of the Plan shall be documented and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in design, construction,
operation, or maintenance which has a significant effect on the potential for the discharge of pollutants to
surface waters. All aspects of the Stormwater Pollution Prevention Plan shall be reviewed and updated on
an annual basis. The annual update shall include an updated list of significant spills or leaks of pollutants for
the previous three years, or the notation that no spills have occurred. The annual update shall include
written re -certification that the stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. Each annual update shall include a documented re-evaluation of the effectiveness of the BMPs
listed in the BMP Summary of the Stormwater Management Plan.
8. The Director may notify the permittee when the Plan does not meet one or more of the minimum
requirements of the permit. Within 30 days of such notice, the permittee shall submit a time schedule to the
Director for modifying the Plan to meet minimum requirements. The permittee shall provide certification in
writing (in accordance with Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the
changes have been made.
9. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of the
Preventative Maintenance and Good Housekeeping Program at a minimum on a semi-annual schedule,
once during the first half of the year (January to June), and once during the second half (July to December),
with at least 60 days separating inspection dates (unless performed more frequently than semi-annually).
These facility inspections are different from, and in addition to, the stormwater discharge characteristic
monitoring required in Part I of this permit.
10. Implementation. The permittee shall implement the Plan. Implementation of the Plan shall include
documentation of all monitoring, measurements, inspections, maintenance activities, and training provided
to employees, including the log of the sampling data and of actions taken to implement BMPs associated
with the industrial activities, including vehicle maintenance activities. Such documentation shall be kept on -
site for a period of five years and made available to the Director or the Director's authorized representative
immediately upon request.

Subject: NC0003760-DuPont Kingston and NC0032077-Contentnea MSD
Mr. Templeton (Mike),
Marshall Hyatt transferred these 2 permits to me when the change of
oversight was made a couple of weeks ago.
The intentions of NCDENR to modify these permits (NC0003760-DuPont
Kingston and NC0032077-Contentnea MSD) to reflect the transfer of total
nitrogen allocation from DuPont -Kingston to the MSD seems clear and
concise. EPA Region 4 has no comments pertaining to that matter. The
other revisions to the Contentnea MSD WWTP permit to update the
Effluent Limitations and Monitoring Requirements also seems appropriate.
Please proceed with issuing these permits as your scheduling allows,
and please forward a copy of the final, signed and dated permits to me
when they become available. Electronic copies are welcomed.
Thank you,

I. PROPOSED PERMIT ACTION
The Contentnea MSD and DuPont -Kinston Plant requested modification of their respective NPDES
Permits NC0030716 and NC0003760 to reflect the transfer of nitrogen allocation from the Kinston Plant
to the MSD. The Division made a tentative determination to modify the permits as requested.
II. BACKGROUND
The DuPont -Kinston Plant WWTP is located in Lenoir County in the Neuse River basin and was
assigned Total Nitrogen (TN) allocation under the Neuse River Basin Nutrient Management Strategy rule
for Wastewater Discharges (T15A NCAC 02B .0234), or "the Neuse rule."
In 2007, the previous owner, UNIFI-Kinston, sold the MSD an option to purchase up to 5,000 Ib/yr of
discharge allocation (3,500 Ib/yr as estuary allocation). On March 17, 2010, the MSD purchased the
entire amount. The MSD and the Kinston Plant are both located in the 70% transport zone of the Neuse
River basin. Thus, both the estuary and discharge allocations transfer from one facility to the other on a
pound -for -pound basis.

The transfer would reduce the Plant's TN discharge allocation to 25,493 Ib/yr (17,845 Ib/yr as estuary
allocation). In 2009, the Plant discharged 5,040 Ib of nitrogen, and from mid-2009 to mid-2010 it
discharged 4,780 Ib. The low loadings are due in large part to the fact that production at the facility has
been minimal since DuPont resumed ownership. The company will limit future production as necessary
to ensure it does not exceed the remaining allocation.
III. DESCRIPTION OF PERMIT CHANGES
The draft permit includes the following changes:
• Total Nitrogen (TN) Limits. The facility's nitrogen discharge limit in Condition A.(1.) is decreased from
30,493 Ib/yr to 25,493 Ib/yr. The proposed change in the TN limit would become effective on January
1, 2011, that is, at the beginning of the upcoming calendar year.
• TN Allocation. Condition A.(7.), Total Nitrogen Allocations, is also revised to reflect the transfer of
allocation.
PUBLIC COMMENTS
The Division published notice once each in The Daily Reflector (Pitt County) on September 17, 2010,
and in the Goldsboro News-Argus (Wayne County) on September 22, 2010, inviting public comment on
the draft permits. No comments were received except for EPARegion IV's concurrence with the
proposed modifications.
FINAL ACTION
The Division is issuing the permits as proposed, with the following dates:

Re: NPDES Permit Modification
Contentnea Metropolitan Sewerage District (NC0032077)
Dupont -Kinston, Inc. (NC0003760)
Dear Mr. Templeton:
On March 17, 2010 the Contentnea Metropolitan Sewerage District and Unifi Kinston entered
into an agreement in which 3,500 pounds, at the Estuary, of annual mass loading limit for total
nitrogen would be sold. Under the agreement, the Contentnea Metropolitan Sewerage District
purchased said Total Nitrogen Allocation from Unifi Kinston for a purchase price of $1,400,000.
An Asset Purchase and Sale Agreement between DuPont and Unifi dated February 29, 2008
conferred to Unifi the right to sell the Offered TN Allocation and to keep the sales proceeds.
Please find attached Bill of Sale which addresses this matter.
By authority of this letter, the Contentnea Metropolitan Sewerage District and DuPont -Kinston
are requesting that their respective NPDES permits be modified to reflect this transaction. It is
requested that NPDES Permit NC0032077 (Contentnea Metropolitan Sewerage District) be
increased 3,500 pounds at the Estuary and NPDES Permit NC0003760 (DuPont -Kinston) be
