Subject: NPDES Permit Modification
Permit Number NC0003760

Dear Mr. Proctor:
Division personnel have reviewed your October 24, 2005 request for modification of the subject permit.
Accordingly, we are forwarding the attached final NPDES discharge permit. Please place the amended permit pages in
permit and discard the old pages. 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 May 9, 1994 (or as subsequently amended).
The expiration date was changed in error when the name change took effect in October 2004 and has been corrected
in this modification. In regard to the change in the metals monitoring, quarterly monitoring has been eliminated from
Condition A.(1.) of this permit for Chromium, Copper, Lead, Nickel, and Zinc; however, annual monitoring requirements for
these parameters remain in Condition A.(2.). Please note that in the event that the analysis for any parameter listed in
Condition A.(2.) equals or exceeds its Practical Quantitation Limit, the monitoring frequency for that parameter shall
immediately increase to once per quarter. When 12 consecutive quarterly samples using appropriate laboratory methods
do not detect the parameter, the monitoring frequency for that parameter shall immediately return to once per year.
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 permit shall be final and binding.
Please take notice that this permit is not transferable. 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, Coastal Area Management Act, or any other Federal or Local governmental permits which may be required.
If you have any questions or need additional information, please do not hesitate to contact Maureen Crawford of my
staff at [phone], extension 538.
Sincerely,
led

I'm working with Mr. Ed Warren at the Regional office in Washington. I'm requesting that the quarterly monitoring
removed from 001 sample point based on reasonable potential analysis due to annual monitoring not having had any
problems with 001 for metals. The permit has metals already listed under annual sampling with proposed limits in
place. This situation has caused problems with the NC's database system.
Also in the last inspection it was brought to our attention that the permit due date was changed on the first couple
pages to as different renewal date. It appears a copy and paste error was in place.

To: Sergei Chernikov <[e-mail]>
Sergei,
1. I have attached the INVISTA permit additions to cover stormwater at the three
newly -identified stormwater outfalls. I have arranged them mostly page by page in
the order of the 2003 permit. I'm sending them to you for review.
2. I'll be glad to insert the stormwater portions into your permit text, if you will
send me the permit text. Or, if it's easier for you, you can insert my additions
into the text. Either way is ok with me.
3. I have not received a signed EPA Form 2F from INVISTA. I spoke to Jay Vincent
about it earlier this week, and he reports contacting INVISTA. Until we get a
response from INVISTA and Jay, I don't want to issue the permit.
4. I apologize for delaying this for so long.

INVISTA TRANSMITTAL LETTER 9/28/04
(Sergei, I see on p. 3 of their 9/28/04 letter that CRA says, "It is INVISTA's understanding
that, after review of the permit modification information submitted herein, the NPDES unit,
in consultation with the Stormwater Permitting unit, will establish parameters for
monitoring, after which the facility will have one year to perform sampling and submit the
analytical results required by NCDENR." What I think I remember was more like DWQ is
always receptive to a reduction in monitoring requirements based on new data. I don't
have any notes or correspondence supporting my vague recollection, however. Our current
procedure is to require twice per year stormwater monitoring on constituents that we
suspect may be on site. The applicant has not provided us with sufficient information to
reduce the list of pollutants, so I have relied on the wastewater parameters in A(1), A(2),
A(3), and A(4), and on selected parameters identified in the tables attached to EPA Form
2F.
EPA FORM 2F
Unsigned by applicant. Signatures are required in part V.B. certifying the absence of non-
stormwater flows in each stormwater outfall, and in part X. certifying the accuracy of the
submittal information. I have spoken with Jay Vincent, CRA, and requested a fax copy,
signed. Jay is also going to clear up some minor errors in the lat and long, and in the
narrative description of Outfalls 004 and 006. I suggest that we do not issue the
permit until INVISTA signs EPA Form 2F, as required by the instructions for that
form.
PERMIT COVER SHEET
... INVISTA S.a r.I.
is hereby authorized to discharge wastewater and stormwater from a facility located at
INVISTA Kinston Fiber Plant
SUPPLEMENT TO PERMIT COVER SHEET
3. Discharge stormwater into an unnamed tributary to Beaverdam Branch (Outfall
004), and discharge stormwater into an unnamed tributary to the Neuse River
(Outfall 005), and discharge stormwater into an unnamed tributary to the
Neuse River (Outfall 006), all of which are Class C NSW waters in the Neuse
River Basin, at the locations specified on the attached map.
VICINITY MAP
(Note that item 2. of the SUPPLEMENT TO PERMIT COVER SHEET references the outfall
locations shown on the attached map, which should be modified to reflect the relocation of
Outfall 002 and the locations of new Outfalls 004, 005, and 006.)

A.(1.) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
- Outfall 001
During the period beginning on the effective date of this permit and lasting until expiration,
the Permittee shall be authorized to discharge treated process and sanitary wastewaters,
remediated groundwater, non -contact cooling water, and stormwater from Outfall 001
subject to the effluent limitations and monitoring requirements below and in Condition A.2.
of this permit:(minor mod, as requested by the permittee) (Sergei, note that footnote 3 on
this page references A(4) and A(5), which don't match up on my copy of the permit.)
A.(2.) ADDITIONAL EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
- Outfall 001
(Sergei, FYI - - I don't have any stormwater requirements to add to this page, but I do have
a question. INVISTA submitted an EPA Form 2F and indicated in part VILE. the onsite
presence of O&G, acetaldehyde, ally/ alcohol, formaldehyde, xy/ene, acrolein, Hg, and
cobalt, none of which are present in the current wastewater permit limitations pages. I
don't know whether or not these parameters were considered in the wastewater evaluation,
or perhaps were in earlier versions of the permit and then removed based on confirmed
absence in the discharge.)
A.(3.) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
- Outfall 002
(No stormwater additions.) (Sergei, it looks like the preliminary RPA recommendation
included arsenic, but I don't see arsenic in the permit. I was going to include it in the
stormwater portion. Is there a reason that arsenic was left out of the permit?)
A.(4.) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
- Outfall003
During the period beginning on the effective date of this permit and lasting until expiration,
the Permittee shall be authorized to discharge non -contact cooling water, steam
condensate, and stormwater from Outfall 003 subject to the following effluent limitations
and monitoring requirements: (minor mod, as requested by the permittee) (Sergei, it looks
like the preliminary RPA recommendation included arsenic, but I don't see arsenic in the
permit. I was going to include it in the stormwaterportion. Is there a reason that arsenic
was left out of the permit?)
A.(5.) CALCULATION OF TOTAL NITROGEN LOADS
A.(6.) ANNUAL LIMITS FOR TOTAL NITROGEN
(No stormwater additions. Sergei, I don't think we should add stormwater from Outfalls
004, 005, and 006 into this calculation, right?)
A.(7.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
(No stormwater additions.)

A.(8.) BIOCIDES
A.(9.) INSTREAM MONITORING
A.(10.) NON -DETECTION REPORTING AND DETERMINATION OF COMPLIANCE
(No stormwater additions.)
NEW A.(11.) EFFLUENT LIMITATIONS AND MONITORING REOUIREMENTS
- Outfall 004
(Note that I've added the new sections at the end, rather than in sequence with Outfalls
001, 002, 003, so that we won't have to make additional changes to footnotes and text
references.)
During the period beginning on the effective date of this permit and lasting until
expiration, the Permittee shall be authorized to discharge stormwater from Outfall
004 subject to the following monitoring requirements. All analytical monitoring
shall be performed during a representative storm event.

NEW A.(14.) QUALITATIVE STORMWATER MONITORING
Qualitative monitoring requires a visual inspection of each stormwater outfall
(Outfalls 004, 005, 006) regardless of representative outfall status and shall be
performed as specified below. Qualitative monitoring is for the purpose of
evaluating the effectiveness of the Stormwater Pollution Prevention Plan (SPPP)
and assessing new sources of stormwater pollution. No analytical tests are
required. The Permittee shall conduct qualitative monitoring during a stormwater
discharge, but not necessarily during a stormwater discharge resulting from a
representative storm event.
In the event an atypical condition is noted at a stormwater discharge outfall, the
Permittee shall document the suspected cause of the condition and any actions
taken in response to the discovery. This documentation will be maintained with
the Stormwater Pollution Prevention Plan.
All qualitative monitoring will be performed twice per year, once in the spring
(April - June) and once in the fall (September - November).

NEW A.(15.) STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, hereinafter
referred to as the Plan. The Plan shall be considered public information. The Plan
shall include, at a minimum, the following items:
1. Site Plan. The site plan shall provide a description of the physical facility
and the potential pollutant sources that may be expected to contribute to
contamination of stormwater discharges. The site plan shall contain the
following:
(a) A general location map (USGS quadrangle map or comparable map),
showing the facility's location in relation to transportation routes
and surface waters, the name of the receiving waters to which the
stormwater outfalls discharge, or if the discharge is to a municipal
separate storm sewer system, the name of the municipality, and the
ultimate receiving waters, and accurate latitude and longitude of the
points of discharge.
(b) A narrative description of storage practices, loading and unloading
activities, outdoor process areas, dust or particulate generating or
control processes, and waste disposal practices.
(c) A site map drawn to scale with the location of industrial activities
(including storage of materials, disposal areas, process areas, and
loading and unloading areas), site property boundaries, drainage

structures, drainage area boundaries, total area for each outfall,
activities occurring in each drainage area, building locations, existing
BMPs, impervious surfaces, and the percentage of each drainage area
that is impervious. For each outfall, a narrative description of the
potential pollutants that could be expected to be present in the
stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at
the facility during the three previous years and any corrective actions
taken to mitigate spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the
presence of non-stormwater discharges. The certification statement
must be signed in accordance with the requirements found in Part III,
Standard Conditions, Section B, Paragraph 3.
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) Feasibility Study. 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 Schedule. A schedule to provide secondary
containment for bulk storage of liquid materials, storage of Section
313 of Title III of the Superfund Amendments and Reauthorization
Act (SARA) water priority chemicals, and storage of hazardous
substances to prevent leaks and spills from contaminating
stormwater runoff. If the secondary containment devices are
connected directly to stormwater conveyance systems, the
connection shall be controlled by manually activated valves or other
similar devices (which shall be secured 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 the material stored within the
containment area. 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 narrative description shall be provided of Best
Management Practices (BMPs) to be considered such as, but not

limited to, oil and grease separation, debris control, vegetative filter
strips, infiltration, and stormwater detention or retention, where
necessary. The need for structural BMPs shall be based on the
assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through
monitoring of stormwater discharges.
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 team)
responsible for implementing the SPRP shall be identified. 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
materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan 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 program shall be developed and implemented. The program
shall document schedules of inspections and maintenance activities of
stormwater control systems, plant equipment, and plant systems.
Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
5. Employee Training. Training schedules shall be developed and training
provided at a minimum on an annual basis on stormwater protection
principles, proper spill response and cleanup procedures, and preventative
maintenance activities for all personnel involved in 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.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify
the specific position(s) or person(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 that has a
significant effect on the potential for the discharge of pollutants to surface
waters. The Stormwater Pollution Prevention Plan shall be reviewed and
updated on an annual basis.
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 to the Director that the changes have been
made.

8. Facility Inspection Program. The Permittee must inspect all stormwater
systems on at least a quarterly schedule, once in the periods of January -
March; April - June; July - September; and October - December. The
inspection and any subsequent maintenance activities performed shall be
documented, recording date and time of inspection, individual(s) making
the inspection, and a narrative description of the facility's stormwater
control systems, plant equipment, and plant systems. Records of these
inspections shall be incorporated into the Stormwater Pollution Prevention
Plan.
9. Implementation. The Permittee shall document all monitoring,
measurements, inspections, maintenance activities, and training provided to
employees, a log of the sampling data, and a record of actions taken to
implement BMPs. Such documentation shall be kept on -site for a period of
five years and made available to the Director or his authorized
representative immediately upon request.

and complete. I am aware that there are significant penalties for submitting false
information, including the possibility of fines and imprisonment for knowing
violations."
III. C. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
3. Bypassing of Stormwater Control Facilities
Bypass is prohibited and the Director may take enforcement action against a
permittee for bypass unless:
a. Bypass was unavoidable to prevent Toss of life, personal injury or
severe property damage; and
b. There were no feasible alternatives to the bypass, such as the use of
auxiliary control facilities, retention of stormwater or maintenance
during normal periods of equipment downtime or dry weather. This
condition is not satisfied if adequate backup controls should have
been installed in the exercise of reasonable engineering judgment to
prevent a bypass which occurred during normal periods of equipment
downtime or preventive maintenance; and
c. The permittee submitted notices as required under, Part III, Section E
of this permit.
If the Director determines that it will meet the three conditions listed
above, the Director may approve an anticipated bypass after considering its
adverse effects.
M.D. MONITORING AND RECORDS
I. Representative Sampling
Samples collected and measurements taken, as required herein, shall be
characteristic of the volume and nature of the permitted discharge.
Analytical sampling shall be performed during a representative storm event.
Samples shall be taken on a day and time that is characteristic of the
discharge. All samples shall be taken before the discharge joins or is
diluted by any other waste stream, body of water, or substance. Monitoring
points as specified in this permit shall not be changed without notification
to and approval of the Director.
5. Representative Outfall
If a facility has multiple discharge locations with substantially identical
stormwater discharges that are required to be sampled, the permittee may
petition the Director for representative outfall status. If it is established
that the stormwater discharges are substantially identical and the permittee

is granted representative outfall status, then sampling requirements may be
performed at a reduced number of outfalls.
6. Records Retention
Visual monitoring shall be documented and records maintained at the
facility along with the Stormwater Pollution Prevention Plan. Copies of
analytical monitoring results shall also be maintained on -site. The
permittee shall retain records of all monitoring information, including all
calibration and maintenance records and all original strip chart recordings
for continuous monitoring instrumentation, and copies of all reports
required by this individual permit for a period of at least 5 years from the
date of the sample, measurement, report or application. This period may be
extended by request of the Director at any time.
7. Inspection and Entry
The permittee shall allow the Director, or an authorized representative
(including an authorized contractor acting as a representative of the
Director), or in the case of a facility which discharges through a municipal
separate storm sewer system, an authorized representative of a municipal
operator or the separate storm sewer system receiving the discharge, upon
the presentation of credentials and other documents as may be required by
law, to;
a. Enter upon the permittee's premises where a regulated facility or
activity is located or conducted, or where records must be kept under
the conditions of this individual permit;
b. Have access to and copy, at reasonable times, any records that must
be kept under the conditions of this individual permit;
c. Inspect at reasonable times any facilities, equipment (including
monitoring and control equipment), practices, or operations regulated
or required under this individual permit; and
d. Sample or monitor at reasonable times, for the purposes of assuring
individual permit compliance or as otherwise authorized by the Clean
Water Act, any substances or parameters at any location.
III. E. REPORTING REQUIREMENTS
4. Non-Stormwater Discharges
If the storm event monitored in accordance with this individual permit
coincides with a non-stormwater discharge, the permittee shall separately
monitor all parameters as required under the non-stormwater discharge
permit and provide this information with the stormwater discharge
monitoring report.
VI. DEFINITIONS
3. Allowable Non-Stormwater Discharges

Non-stormwater discharges which shall be allowed in the stormwater
conveyance system are:
(a) All other discharges that are authorized by a non-stormwater NPDES
permit.
(b) Uncontaminated groundwater, foundation drains, air -conditioner
condensate without added chemicals, springs, discharges of
uncontaminated potable water, waterline and fire hydrant flushings,
water from footing drains, flows from riparian habitats and wetlands.
(c) Discharges resulting from fire -fighting or fire -fighting training.
4. Best Management Practices (BMPs)
Measures or practices used to reduce the amount of pollution entering
surface waters. BMPs may take the form of a process, activity, or physical
structure.
5. Bypass
A bypass is the known diversion of stormwater from any portion of a
stormwater control facility including the collection system, which is not a
designed or established operating mode for the facility.
6. Bulk Storage of Liquid Products
Liquid raw materials, manufactured products, waste materials or by-
products with a single above ground storage container having a capacity of
greater than 660 gallons or with multiple above ground storage containers
located in close proximity to each other having a total combined storage

The maximum 24-hour precipitation event expected to be equaled or
exceeded, on the average, once in 25 years.
PROPOSED PARAGRAPH TO BE INCLUDED IN THE PERMIT TRANSMITTAL LETTER
The permit requires stormwater monitoring for a fairly broad set of parameters
based on the constituents monitored in the wastewater discharges and based on
the constituents reported to be on site. In general, the September 2004 permit
modification request contained insufficient data to provide a basis for DWQ to
reduce the stormwater monitoring requirements. DWQ will consider any future
request from INVISTA to reduce the stormwater monitoring requirements for
specific parameters after the collection of one year of data, i.e., a minimum of two
semi-annual monitoring results.
