A.(5.) CALCULATION OF TOTAL NITROGEN LOADS
(a.) The Permittee shall calculate monthly and annual TN Loads as follows:
(1.) Monthly TN Load (lb/mo) = TN x TMF x 8.34
where:
(h)
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 (lb/yr) = Sum of the 12 Monthly TN Loads for the calendar year
The Permittee shall report monthly Total Nitrogen results (mg/L and lb/mo) in the discharge
monitoring report for that month and shall report each year's annual results (lb/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.)
Allowable changes include those resulting from purchase of TN allocation from the
Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation between the
Permittee and other dischargers; regionalization; and other transactions approved by the
Division.
(ii.) The Permittee may request a modification of the TN Load limit in this Permit to reflect
allowable changes in its TN allocation. Upon receipt of timely and proper application, the
Division will modify the permit as appropriate and in accordance with state and federal
program requirements.
(iii.) Changes in TN limits become effective on January 1 of the year following permit
modification. The Division must receive application no later than August 31 for changes
proposed for the following calendar year.
(iv.) Application shall be sent to:
NCDWQ / NPDES Unit
Attn: Neuse River Basin Coordinator
Mail Service Center
Raleigh, NC 27699-1617
(d.) If the Permittee is a member and co-permittee of an approved compliance association, its TN
discharge during that year is governed by that association's group NPDES permit and the TN
limits therein.
(i.) The Permittee shall be considered a Co-Permittee Member for any given calendar year in
which it is identified as such in Appendix A of the association's group NPDES permit.
Part I, Page 6 of 21

Permit No. NC0003760
(ii.) Association roster(s) and members' TN allocations will be updated annually and in
accordance with state and federal program requirements.
(iii.) If the Permittee intends to join or leave a compliance association, the Division must be
notified of the proposed action in accordance with the procedures defined in the
association's NPDES permit.
(A) Upon receipt of timely and proper notification, the Division will modify the permit as
appropriate and in accordance with state and federal program requirements.
(B) Membership changes in a compliance association become effective on January 1 of the
year following modification of the association's permit.
(e.) The TN monitoring and reporting requirements in this Permit remain in effect until expiration of
this Permit and are not affected by the Permittee's membership in a compliance association.
A.(7.) 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 1.9%.
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 Branch
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

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.
A.(8.) 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

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 shall 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).

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.
Part I, Page 13 of 21

Permit No. NC0003760
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
Part I, Page 14 of 21

Permit No. NC0003760
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 shaII be kept on -site for a period of five years and made available
to the Director or his authorized representative immediately upon request.

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.

Permit No. NC0003760
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 capacity of greater than 1,320 gallons.
14. Municipal Separate Storm Sewer System
A stormwater collection system within an incorporated area of local self-government such as a
city or town.
17. Point Source Discharge of Stormwater
Any discernible, confined and discrete conveyance including, but not specifically limited to, any
pipe, ditch, channel, tunnel, conduit, well, or discrete fissure from which stormwater is or may
be discharged to waters of the state.
18. Representative Storm Event
A storm event that measures greater than 0.1 inches of rainfall and that is preceded by at least 72 hours
in which no storm event measuring greater than 0.1 inches has occurred. A single storm event may
contain up to 10 consecutive hours of no precipitation. For example, if it rains for 2 hours without
producing any collectable discharge, and then stops, a sample may be collected if a rain producing a
discharge begins again within the next 10 hours.
19. Representative Outfall Status
When it is established that the discharge of stormwater runoff from a single outfall is representative
of the discharges at multiple outfalls, the DWQ may grant representative outfall status.
Representative outfall status allows the permittee to perform analytical monitoring at a reduced
number of outfalls.
20. Rinse Water Discharge
The discharge of rinse water from equipment cleaning areas associated with industrial activity.
Rinse waters from vehicle and equipment cleaning areas are process wastewaters and do not
include washwaters utilizing any type of detergent or cleaning agent.

SUMMARY
Unifi submitted their request for modification of their permit on 12/01/2005. The
modification required significant input from Stormwater Unit, which caused
significant delay in processing the request. Comments from Stormwater Unit were
received on 05/25/2006.
PROPOSED CHANGES
1. Stormwater was added to Outfall 001 and Outfall 003 as a permitted discharge.
2. Steam Condensate was added to Outfall 001 as a permitted discharge.
3. Outfall 002 was relocated to a location downstream in order to incorporate the
potential additional stormwater runoff over the C8&D and Ash Landfills New
outfall coordinates are: Lat. 350 19' 26", Long. 770 08' 56"
4. Stormwater Outfalls 004 (Lat. 350 20' 09", Long. 770 28' 51"), 005 (Lat. 350 19'
59", Long. 770 28' 10"), and 006 (Lat. 350 19' 35", Long. 770 28' 18") were
added to the permit.
5. Low -flow leachate from Old Landfill (SWMU3), Original Ash Landfill and New
Ash Landfill was permitted to be treated at WWTP and subsequently discharged
through Outfall 001. Total estimated flow from these sources is 0.15 gpm.
Leachate Source and Description - Sample Location 9
The two inter -connected leachate collection areas, collectively identified as Sample Location 9, consists of
the Boil Out Neutralization Chamber (SWMU 23) which is an in -ground concrete sump and chamber
constructed from reinforced concrete. The sump is in close proximity to an earthen lined open ditch
formerly used as a process wastewater discharge channel (SWMU 12). It is our understanding that the
source of the leachate largely originates from a formerly utilized residue landfill and associated burning

pits identified as SWMU 7 that is situated approximately 1200 ft due west of Sample Location 9. SWMU
7 is comprised of a series of four capped trenches, or pits, and an adjacent 1.5 acre capped landfill.
SWMU 7 is currently listed in the Facility's RCRA Part B Permit Renewal Application which was most
recently filed with the NCDENR Division of Waste Management on August 31, 2005.
Some leachate may also be collected from SWMU 1, located approximately 1625 ft west of Sample
Location 9, which consists of four or five capped glycol pits formerly operated on -Site; however, this
potential source of leachate is believed to be a minor contributor, if at all, to the small amount of leachate
collected at Sample Location 9.

Sergei...here is the response to the remaining question (#2) presented in your email dated June 26, 2006. A brief
description for the source of the leachate that is being collected at the two leachate collection areas, designated as
Sample location 9, and which is described in our letter dated November 9, 2005 is provided as follows.
Leachate Source and Description - Sample Location 9
The two inter -connected leachate collection areas, collectively identified as Sample Location 9, consists of the Boil
Out Neutralization Chamber (SWMU 23) which is an in -ground concrete sump and chamber constructed from
reinforced concrete. The sump is in close proximity to an earthen lined open ditch formerly used as a process

originates from a formerly utilized residue landfill and associated buming pits identified as SWMU 7 that is situated
approximately 1200 ft due west of Sample Location 9. SWMU 7 is comprised of a series of four capped trenches,
or pits, and an adjacent 1.5 acre capped landfill. SWMU 7 is currently listed in the Facility's RCRA Part B Permit
Renewal Application which was most recently filed with the NCDENR Division of Waste Management on August

To: Gil Vinzani <[e-mail]>
Reference the Fact Sheet we were discussing on the phone. Though I could not find it while we were on the phone, I had
previously read on page 1, last paragraph, the reference to "In 1999, DuPont modified one of its production lines did
not require modifications to the permit," and had inferred that this statement was in reference to the new production line that
used acrolein and that they notified us of the change. (on the phone with you, I paraphrased this as saying I though there was
some reference to acrolein in the fact sheet, evidently because I was surmising from this statement that we would have
known what the process chemicals were). If they notified us of the acrolein line and it was an accurate representation of what
they were doing, then our fact sheet statement, "that the process change did not require modifications to the permit,"
indicates we do not need to consider the issue I brought up about would we have increased monitoring and other parameters
analyzed for.

SUBJECT: Notification! Requirements; NPDES Permit NC0003760
This purpose of this letter is follow up to the phone can between you and Sergio Macieisa 1-27-06, and to comply
with the requirements of part 3 section C of the NPDES permit # NC0003760. Unifi has reason to believe that an
activity occurred which resulted in the discharge of acrolein at a concentration ccceeding 200 ug/1.
Testing for the OCPSF was completed on an effluent sample from outfall 001 collected on December 21,2005.
Environment 1 Inc. ran the scans needed for the 4 compounds to be reported. Environment 1 Inc. ran all compounds
on the sett and reported all compounds. Acrolein had a detection of 273 ug/1. Test results from 2002,2003,and
early 2005 indicated acrolein concentrations below the laboratory detection limit at 100 ug/l. Please note that there
have been no violations ions of the effluent limitation for chronic toxicity.
Unifi has =eluded that the source is DuPont's 3G2 process that operates on the Unifi Kinston site as a tenant that
existed prior to Unifi Kinstoa's acquisition of the site in September 2004. The 3G2 process began operation in May
of 2000. Unifi has been unable to find doc unemation indicating that DuPont notified the DWQ about the new
manufactining process.
DuPont provided Unif with a copy of a report "BIOLOGICAL TREATABILITX STUDY TO ASSESS TIE
IMPACTS OF TREATMENT OF N-125 (3GT) WASTEWATER IN KINSTON'S WASTEWATER
TREATMENT PLANT', DuPont Engineering March 27,1998. A copy of the report is attached to this letter.
DuPont intends to expand the 3GT manufacturing facilities. Unifi is investigating the potential impact to the
WWI? operations. Unifi requests assistance from DWQ to determine the requirements to update our current
NPDES peanut for the effluent of the 3C2 process and the future expansion plans for 3G3.
If 1 can be of airy more assistance on this subject I can be contacted at 252-522-6443

BIOLOGICAL TRI"ATABILITY STUDY TO ASSESS THE IMPACTS OF TREATMiENT OF N-125
WASTEWATER IN KINSTON'S WASTEWATER TREATMENT PLANT
A biological wearability study was conducted by Engineering at the Glasgow Wastewater Lab to assess
the potential impacts of treating wastes from the N125 process in Kinston's existing wastewater ncasnievt
system. Pilot runs for the N125 process were conducted at Kinston, and generated wastes anticipated to
be typical of full-scale operations. Representative samples of these wastes were collected for use w
conducting this treatability study_ This material was fed to test units in conjunction with samples of the
current influent to Kinston's wastewater treatment plant
The results of the mcatability study showed that a microorganism population taken frcno the Aston
site's wastewater treatment plant was able to treat wastes from N125 pilot runs in combination with other
site wastewater with )3o observed adverse effects under all conditions tested. Nearly identical resulta
ware obtained for COD and BOD removal in the control unit (Unit 1), which received t' feed consisting
aoiely of tate wastewater treatment plant influent, and the two test units (Units 2 and 3), which received
site wastewater with varying amounts of wastewater from N125 pilot Hans added, COD and BOD
MnayaiAPROIcd big t run Unit 3 during pbase.2 o(t sttudy when the N125 wastewater was added at
twice the pxvjected els, and in Units 2 and-3 in phase 3 when acrolein and alkyl alcohol were added in
twcxvasing amounts.
No difference in total phosphorus removal was observed between the control unit and test units, though
no signfflcRnt removal occurnxl in any of the units. Feed and effluent TKN and nitrate concentrations
indicate significant nitrification occurred in each of the units throughout the study, with the exception of
*Period of apparent ixtbiition in Unit 1. Biomass production autos appeared to be minimal in all of the
mks. Grim the relatively short duration of the study, no attempt to determine yield coefficients was

the biosobOds in the teat units did not differ significantly from chose of the control unit biosolids.'
Effluent samples collected from each of the test units during phases 1 and 2 of the study were tested for •
acme find chronic toxicity to CeriodapIuiiadubia. The samples were diluted to several concentrations
using moderately hard reconstituted water for the testing. Them were no effects observed for arty of the
unit effluents at even the 100% effluent concentration, indicating no acute or chronic toxicity to the test
species.
Overall„ the study proceeded well with very positive results. Indications are that the N125 wastes can be
treated in the site's wastewater trea :neat system without impacting the facility's ability to treat other sire
wastes. Results from phase 2 of the study suggest that this is true at up to twice the projected flows of
• N125 wastewater. Phase 3 of the study sbowed no major short terra impacts of introduction of acrr leis
and allyl alcohol, compounds identified as being of potential concern, at concentuations much higher than
would be expected in Cbe site's wastewater treatment plant influent. The two compounds were
biodegraded or otherwise transformed to below detection levels in the test unit effluent scrams.

BIOLOGICAL TREATABXLfTY STUDY TO ASSESS TBE IMPACTS OF TREATMENT OF
N-125 WASTEWATER IN KINSTON'S WASTEWATER TREATMENT PLANT
don
The purpose of this treatabiliry study was to assess the potential impacts of treating wastes fxona the
N125 process in Kinston's existing wastewater treatment system. Pilot runs for the N125 prnccss weft
conducted et Kinston, and generated wastes anticipated ro be typical of full .scale operations.
Representative samples of these wastes were collected for use in conducting this wearability study. This
material was fed to test units in conjunction with samples of the current influent to KIDStpn s wastewater
treatment plant. -
The following key perforcmmu a criteria were monitored during the study to allow the assessment of
impacts to be made:
the ability to maintain high COD/BOD removal
- effluent concentrations of constituents of concern
- system response to batch/cyclic exposure to the test streams
- system capabilities for handling slugs of above -average
concentrations of constituents of concern
- phosphorus removal end effluent concentrations
biomass production rates and the settleability of the biosolids
-effluent toxicity.
Metkoctsisei
The original scope of work for the study is included as Attachment 1; minor revisions west made to this
plan during the course of the study, After receipt at the WWI,, sampling, andcharacterization, a sample
of biomass forts IGaston's wwtp was divided among three 7.SL Eckeofelder continuous flow units.
During au initial stabilization period, the prehusinary test units were fed Kinston wwtp influent. After
this stabilization period, the biomass from the three writs was combined and then redistributed. The vomits
wute agitated and aerated with supplied air, and maintaincui at an average tetuperatwre of-20°C. A
combination of sludge age (--30 days) and food -to -microorganism (F/M) ratio (0.07-0.15) was used to
control the mixed liquor volatile suspended solids (MLVSS) concentrations in the units through solids
wasting as needed.
The following gives the approximate flow and COD content of the Kinston wwtp influent (see attached)
and N125 waste states;

These flaws were scaled down to the test unit volumes to give hydraulic reteztrion times (HR'r) and
compositions comparable to those projected for the full scale plant. Feed recipes for the control and two
test units were generated accordingly (see Attachment i for details). Feed *fixtures were made up daily

utilizing samples of wwtp influent and N-125 waste supplied by the site. Each of the waste samples used
by me tan were sampled and analyzed for a number of pacatneters for characterization pYuposes. Results
of this characterization work are summarized in Attachment 2_
Throughout the test, the feed to the control unit (Unit 1) remained unmodified site wwtp influent. The
feeds to the two test units (Unit 2 and Unit 3) were varied during the various phases of the testing to
allow'information to be collected for different potential impacts. During phase 1 (9/5 - 10/12197), the
test units were fed mixtures of wwtp influent and N-125 wastewater (vacuum jet barwe)T overflow
wager). Addition of the jet hotwell water to Unit 2 was ramped to the projected levels over the course of
a week, while it was started immediately at this level in Unit 3. About midway through phase I, fire jet
hotwell water feed, to Unit 3 was cycled off fora week and then back on again- Deering phase 2 (10/13 -
10/2S/97), the. feeds to Units 1 and 2 remained the same as in phase I while the rurnount of jet hvtwell

OvetalI, the testing proceeded relatively smoothly. No upsets occurred during the test period, and no
operational problems were experienced. The slight changes in performance observed were largely the
result of variability in the site.'a wwtp influent. No foaming or other problems were noted in the daily
visual observations of the units.
MLVSS levels (Figures 4, 5, and 6) were maintained in the range of 1000-2000 mg/L. In each of the
reamers throughout the study, and were typically between 1000 and 1500 naglt.. Initially, solids were
washed in an effort to achieve a sludge age of 3D days. With relatively low biomass production in each of
the unite. MLVSS levels dropped to —1000 mg/L and wasting was discontinued. The F/M ratio (based on
soluble COD and 143,VSS, fgJday COD)/rg MLVSSJ) for each unit is shown in Figure 7. These values
varied over the course of the study, largely as the result of changes in Kinston wwtp influent drum
samples. The F/M ratio averaged 0.11 in Units 1, 2. and 3.
Specific oxygen ups rate (SOUR) data for the test units is given in Figure 8. The SOUK, or
resphation rate, is the amount of oxygen used per unit mass of ni cnnorganisms as they degrade
conatimerts in the wad stream. It provides a measure of biological activity. Values for the units ranged
from Ic s than 1 mg OA Ml.VSS/hr in Units 2 and 3 near the start of the study to 16 tug Os/g MLVSs/l,r
in Unit 3 at the start of phase 2. With the exception of Unit 2 in phase 3, no significant differences in
SOUR were observed betweea, the ,control and test units. During phase 3, Unit 2 received iiocreasiug
arodunis of acrolein added to its feed strcrun and bad an average SOUR somewhat higher than the other
two units. The SOUR averaged 9.80 mg Oz/g MLVSS/hr in Unit 2 during phase 3 compared to 4.89 and
6.83 mg O,/g IVIi.VS5/hr in Units 1 and 3, respectively.

- COD and DOD Removal
Soluble COD levels in the feed and effluent of each of the reactors axe given in Figures 9, 10, and 1.1.
Despite the variable nature of the COD content of the feed streams. which were generally higher at the
start of a new dnnn of wwtp influent and decreased over the time period die drum was in service, the
efflueet COI) levels were consistcut!y low in each of the test units. In Unit 1, the COD of tie feed
averaged 348 rng/t. over the course of the study; fn Units 2 and 3 it was slightly lower at 323 and 327
nog/L, respectively. This deflects the fact that the jet hotwelt water, had a low= COD content than the
wwtp influent. Effluent COD averaged 20 mg/L for Unit 1., and 17 mg/L in both Unit 2 and Unit 3.
Soluble COD removal efficiencies for the three units are shown in Figure 12. For all units, > 85% COD
removal was observed throughout the test, with values typically 90% or greater. COD removal averaged
.93% in Unoit 1 and 94% in Units 2 and 3. These values are consistent with the average COD removal
• efficiency of 93% observed in the site's wwtp during approximately the same time period (g/1/97 -
12J31/97).
Trends in the data for soluble 5-day biochemical oxygen demand (BOW were similar to that for COD.
Figures 13, 14, and 15 show feed and effluent HOD, levels for the test units, and Figure 16 shows
removal efficiencies. The effluent BODY levels for all three units were consistently very Low throughout
the test, averaging less than 4 mg& for each. Over the coarse of the study, soluble BODY, was removed
with an average of 97.7% efficiency in Unit 1., 97,8% efficiency in Unit 2, and. 97.9% in Unit 3..
Note; M deacribed above, the values for COD and BOD5 include only the soluble portion of these
parameters. Susded solids present typically result in sorxze amount of COD and BODs. and as such
would add to the values reported.

Nitrogen $alance and Nitrification
' Concentrations of total kjcldahl (organic + ammonia) nitrogen (TKN) in the feed and effluent of each of
the test units are shown in Figures 20, 21. and 22. Relative to soluble COD and BODs. feed TKN levels
for each unit were more consistent from the start to the finish of a wwtp influent drum. as well as from
drum to drum. The feed to Units land 2 averaged 18 mg/L of TKN, while that to Unit 3 averaged 20
mg/L.. Residual levels of TKN in the Effluent of Units 2 and 3 were low thriughout the test, averaging 2
mg/L in both cases. In Unit 1, however, effluent TKN Ievels were low initially but thenincreased to
Levels nearly comparable to that of the feed before decreasing to relatively low concentrations once again
near the end of the study. This fluctuadon in the effluent concentration can largely be attributed to
chagges in nitrification tares in the unit,
Though it is not a significant process in the operation of Kinston's full-scale wwtp, nitrification did play
a amyor role in the nitrogen balance in the three test units. Figtucs 23, 74, and 25 show the feed and
effluent levels of NO3, the end product of nitriftcation, for each of the test units. he data are reported as
nitrogen. Nitrite avOJ, an intermediate product in the overall nitrification process, was else monitored
in each unit's feed and effluent but wan found only et very tow concentrations. As can be seen, the •
effluent NO, concentrations are generally much higher than the feed concentrations, indicative of
nitrification occurring. The exception, to this is in Unit 1 during the period corresponding to the higher
TKN effluent levels when feed and effluent NO;-N Levels were'essentially equivalent. It appears that the
nitrification process Was inhibited during this time. The calve not 1 a
readily apparent as parameters
such as temperature and pH which can impact nitrification raves remained steady during this tune. The
Phase in performance did seem to generally correlate with the change in influent drums which occurred
on 10/10/97.
On tb.e average, the increase in NO3 levels in the test units can account for -60% of the decrease in TIN
levels. The remaining 5-7 mg/L of Tlel removed represent a relatively low amount of nitmgen
'utilization for the amount of soluble BOD3 removed. A typical ratio for utilization of nitrogen with the
removal of BOD is 100:5 for BOD:nitrogen on a weight basis. The actual ratios observed were 100:2.3
in Unit I,100:3.0 in Unit 2, and 100:3.2 in Unit 3.

Frame 26 gives the results of the sludge volume index (SVI) analyses nm on sales from the three units
during the study. The SVI analysis provides a measure of how compactly the solids in a sludge settle
within a prescribed time interval (30 minutes). Sludges with good settling characteristics typically have
an SVI gf 1M0 mUg or less. As can be seen ill Figure 2b, all of the SVI data for the three mita are well
above 100 fig. The data for each of the units largely tracked that of the others for much of die study.
During the second ham of the study, however, the control unit (Unit 1) generally had higher results than
either of the tesc units,
In Figure 27, the zone settling velocity (;ASV) data for each of the unirs-are$Novvrs' AS 'data be-atpedid,
the data show an inverse relationship with the MLSS concentration in each unit; the high esi ZSV values
occur at the lowest MLSS concentrations and the lowest ZSV values at higher MLSS concentrations.
This is as *result of the hindered ability of displaced water to pass through the sealing bulk solids layer
in the zone seating regime as the solids content of that layer increases. The exception to this occurred in
Unit 2 during phase 3 of the study, when relatively stable MLSS concealsations corresponded to
inctRasing ZSV values, This is indicative of improving settling charactctistips. Unit 2 ZSV values began
to approach hose in Unit 3 in phase 4 of the study when each of the units received the same feed.

The results of the dreatability study showed that a microorganism population taken from the Kinston
she's wastewater treatment plant was able to treat wastes from N 1.25 pilot runs in combination with other
site wastewater with no observed adverse effects under all conditions rested, Nearly identical results
were obtained for COD and BOD removal, ire the control wont, (Unit 1) which received a feed consisting
solely of site wastewater treatment plant influent, and the two test units (Units 2 and 3) which received
site wastewater with varying amounts of wastewater from N125 pilot runs added. For all of the units,
average soluble COD removal efficiencies of 93-94% and soluble BOD removal efficiencies of 97+%
were observed. COD and BOA removal remained at these levels is Unit 3 during phase 2 of the stay
when the N125 wastewater was added at twice the projected levels, and in Units 2 and 3 in phase 3 when

Phosphorus removal is an imporraut capability of the Kinston wastewater treatment systeni and thus the
mat onus were monitored to determine if this ability was affected by the introductiou of the N125 wastes.
No difference in total phosphorus removal was observed between the control nail and test units. No
significant removal occarred in any of the units. Though not cuxreody a critical process in Kinston's

Re: Resubmittal of Application for Modification of NPDES Permit # NC0003760
Unifi Kinston LLC
Post Office Box 800
Kinston, North Carolina 28502
Lenoir County
Unifi Kinston LLC (Unifi) is submitting this application for certain modifications of the existing
NPDES Permit issued for the Kinston Facility on March 10, 2003 (NPDES Permit # NC0003760).
This application provides follow-up documentation to the original Application for Permit
Modification which was submitted by INVISTA S.a.r.l. on September 28, 2004. As you are
aware, Unifi subsequently purchased the facility after the original request for modification was
submitted.
EPA Forms 1 and 2 F are attached pursuant to previous discussions with North Carolina
Department of Environment and Natural Resources (NCDENR) staff including Mr. Tom
Belnick - NPDES Permitting Unit - and Mr. Bradley Bennett and Mr. Ken Pickle - Stormwater
Permitting Unit. Forms 2C and 3, are not required for this submittal as directed by NCDENR
personnel pursuant to 15A NCAC 02H.0105(a). Based on our discussions, Unifi understands
that the permit modifications, it is seeking at this time, are considered minor modifications.
Unifi is providing representative analytical data for the additional stormwater outfall locations
referenced in this application as Outfalls 004, 005, and 006. Pursuant to recent discussions with
Mr. Ken Pickle of Stormwater Permitting Unit and Mf.Sergei Cherrulcov of the NPDES Unit, the
analytical dataset includes the specific samplir ; requirements set forth in previous
communications and memoranda issued by NCDENR concerning this permit modification
We have attached Table 1 and Figure 1, which present the analytical results and locations of
samples taken during June 2005 for the additional stormwater outfall locations addressed by
this permit modification request.

November 09, 2005
2 - Reference No. 37006
Table 1 also contains stormwater outfall sampling data from the original permit modification
request. In order to establish baseline monitoring data for the stormwater at the locations
addressed by this permit modification request, the facility conducted a sampling effort in
September 2004. As noted in the original application for modification, not all of the September
2004 samples represented valid data due to a lack of spacing between rainfall events and some
quality control issues. Accordingly, the 2004 data should be viewed only as qualitative data
that may not represent actual conditions.
The request for modification of the existing NPDES permit includes the following components:
1) Modification of the existing permit to include stormwater discharge at Outfalls 001 and
003. At present, the facility's NPDES permit does not specifically provide for
stormwater discharge to these outlets. The facility recently conducted a facility
stormwater evaluation that identified the potential for small volumes of stormwater to
enter these outfalls. Outfall 001 receives small volumes of stormwater that enters a
grated process drain near a chemical tank farm in a on to small flows within the
area of tTie WWTP at the southern end of Basin A. Similarly, Outfall 003 includes
amage from asin as w as flows from the parking lot and common entrance area.
0 ow for minor stormwater
discharges to the existing outlets.
2) Re-desi tion of the dischar : e ' oint for Outfall 002 to a location downstream of the
currentl desi ted Outfall 002, in order to incorpo . - e potential additional
stormwater runoff over the C&D and Ash Landfills. As you are aware, these two
landfills have undergone soil cap construction. Both -the C&D and Ash Landfills have
recentclosure-cedification by NCDENR. The downstream relocation of
Outfall 002 would also require moving the current sampling location to the new Outfall
002 discharge point. These changes will allow the facility to incorporate potential
stormwater flows from these areas into its existing sampling program.
3) Addition of Outfalls 004, 005, and 006 to provide for stormwater discharge at these
locations. The areas that each of these outfalls will dram of stormwater are more fully
described in Part IV-B of the enclosed Form 2F and the Form 2F Additional Information.
The potential discharges at these locations are expected to consist of stormwater only.
4) Addition of low -flow leachate from three collection areas to the industrial wastewater
,treatment plant WifflriardNalarges to Outfall 001. Two of the leachate collection
areas, iden ' e as p e Location 9, are located within Basin B and discharge -to -the
IWWTP. Basin C also contains a leachate collection area id ntifi as Sami lP Inc lion
0, which sts of o r rconnected collection ps. This area appears to collect
lea ate om the on and the newer Ash Landfill. The original Ash
Landfill was dosed during the mid 1970s and was formerly used for disposal of ash

November 09, 2005

generated from the coal-fired powerhouse boilers. The new Ash Landfill is a completely
separate landfill that was recently capped as part of the permitted closure process.
Analytical data for Sampling Locations 9 and 10 are included in Table 3. This data was
obtained during the September, 2004 sampling event. The locations for these two
sampling points are also depicted in Figure 1.
In preparation for closure of the C&D Landfill and new Ash Landfill, the facility
previously requested approval to route the resulting leachate of less than 5 gallons per
minute (gpm) to its IWWTP for treatment and disposal. As noted in the Department's
conditional approval letter, dated November 13, 2003, the low flow associated with
dewatering operations is considered minor pending characterization of the leachate.
The facility requests inclusion of the three other leachate collection source flows
described above, with each having n estimated flow of apgroCimateely 0.05 gpm, in the
approved discharge through Outfall 001 following collection and onsite treatment at the
IWWTP.
Finally, please note that the facility is modifying some of its steam condensate lines to discharge
condensate into either the process wastewater line, which is treated by the IWWTP and
discharged via Outfall 001, or to Outfalls 002 and 003, where untreated steam condensate is
currently permitted to discharge. Unifi's understanding of the authorized discharge for Outfall
001 is that it includes all wastewaters generated by the facility's industrial operations, including
boiler blowdown and steam condensate, as long as the wastewaters are treated at the IWWTP
prior to discharge via Outfall 001. Unifi requests confirmation of its understanding of the
permit, or a permit modification to specifically authorize dischar 001, if
necessary. Unifi intends to proceed with a project to pipe the steam con ensate to Outfall
or to Outfalls 002 and/or 003 in the near future, based on its understanding of the current
permit's authorizations.

electrical equipment, process, or operating equipment. Figure 3 shows the facility
layout, and provides the locations of each of the oil and chemical storage areas. Please
note that Figure 3 contains storage and industrial areas that are not exposed to
stormwater. Table 2 contains a list of storage and industrial areas that have currently
been identified for potential exposure to stormwater.
Fuel oil No. 6 is contained in a 1,000,000-gallon capacity AST (#300) in the Powerhouse
Area. Fuel oil No. 6 is pumped into two 12,000-gallon ASTs (#298 & #299) and into two
3,500-gallon ASTs (#257 & #258) for storage. Fuel oil No. 6 is also pumped through
heaters for use in boilers, vaporizers, and the Factory Engine Room. Fuel oil No.6 is

received at the facility by truck at a transfer station located to the northwest of Tank 300,
and is either pumped into storage or directly to the boilers and Factory Engine Room. A
940-gallon AST is used as an oil/water separator for Tank 300.
Fuel oil No. 2 (Diesel) is received at the facility by truck at a transfer station located
northeast of Tank 3, a 130,000-gallon AST. Diesel is stored for use at the facility in
several ASTs including the following:
• 270-gallon emergency fire pump AST (#293)
• two new 550-gallon Detroit emergency fire pump ASTs
• 400-gallon emergency generator AST (#290)
• 300-gallon AST (A);
• two 550-gallon vehicle refill tanks (#285 & #286)
• 6,000-gallon yarn side furnace AST (#23); and
• 130,000-gallon new vaporizers alternate fuel AST (#308).
Gasoline (#282 & #283) and kerosene (#284) are stored at the vehicle refill station in 550-
gallon ASTs.
Four oil -filled transformers, two 6,265-gallon (#1 & #2) and two 10,505-gallon (#3 & #4)
are in use at the facility; however, these transformers are owned and maintained by
Carolina Power & Light Company. The following facility -owned and maintained
substations are also in use: two 1,030-gallon (12A & 12B); one 375-gallon (RR), and two
1,285-gallon (TT & UU).
Lubricating and hydraulic oils are in use in the two outside Factory Engine Room (FER)
air compressors (Area 22) with each having a volume of 150 gallons.
New and waste finish oils are stored at the facility in both the industrial area and tank
farm area. Industrial finish oil is stored in a 10,000-gallon AST (Tank 223). Waste finish
oil is also contained in a 4,000-gallon capacity AST and is treated in a 6,500-gallon waste
finish oil separator in the tank farm area. Finish oil is stored in a 10,000-gallon AST (L-
525), an 8,000-gallon AST (L-357) and an 8,000-gallon AST (K7164) within the tank farm.
Raw materials and other chemicals associated with manufacturing processes are also
stored within the tank farm and industrial area. These materials include ethylene glycol;
1,3 propanediol; triethylene glycol; methanol; and dimethyl terephthalate (powder).
Pesticides, herbicides, soil conditioners, and fertilizers are not applied at the Site except
for the limited use of Parmitol and Roundup in landscaping activities.

The Kinston facility has two former landfills that have undergone soil cap construction
and have recently received approval for closure by the NCDENR Division of Waste
Management - Solid Waste Section. The two former landfills are commonly referred to
as the new Ash Landfill and the C&D Landfill. The new Ash Landfill primarily contains
ash and residue from the coal fired boiler operations conducted at the facility
powerhouse. The C&D Landfill was predominately used for the disposal of
construction and other debris. A third landfill, the original Ash Landfill, is located
adjacent to and due east of the new Ash Landfill and was closed during the mid 1970's.
It is considered to be a separate solid waste management unit of the facility.
ITEM IV C
Structural Controls
The facility uses a variety of structural control measures to prevent and minimize
exposure of significant materials to stormwater runoff or discharge. Table 2 provides
information regarding these structural measures in minimizing exposure to the
proposed stormwater outlets in this application for modification. In addition, the
facility has constructed a 1 million gallon containment pond upstream of Outfall 002 to
prevent the release of significant materials to surface waters in the event of a
catastrophic spill or as a result of water released to combat a major fire incident.
Table 2 provides a summary of discharge or drainage controls such as secondary
containment around containers and other structures. Potential spills occurring at most
oil containing or process chemical ASTs, would be contained in their respective
secondary containment areas. Accumulated liquids in the secondary containment areas
are visually inspected for the presence of oil prior to releasing the contents either onto
the ground surface or into the process sewer. Only valves of manual, open -and -closed
design are in use at the facility for the drainage of diked areas. If oil is present in a
secondary containment area, the accumulated oils would be removed, treated, and
disposed.
The hazardous waste area located at the Site is currently undergoing closure by Dupont.
The hazardous waste area contains grated drains that discharge into sumps with no
drainage or other conveyances in order to prevent access to stormwater. The sumps are
visually inspected and the contents are tested for various parameters prior to removing
water or other liquids.
The Plant wastewater going to the wastewater treatment facility is monitored constantly
by two total organic carbon analyzers. Alarms and diversion facilities are online to

direct any chemicals or oil detected to an emergency retention pond to prevent releases
of significant materials from reaching the Neuse River. Drainage waters are treated
continuously in one treatment unit. No pump transfer is necessary, as the lift pump is
installed permanently. The wastewater plant has recently experienced a substantial
reduction in flow which currently ranges between approximately 450,000 to 600,000
gallons/ day.
Nonstructural Controls
The Site employs a variety of nonstructural measures and Best Management Practices
(BMPs) to prevent or minimize potential exposure to stormwater runoff including the
use of:
1) Materials management practices including chemical tracking and inventory control;
2) SPCC Plan implementation and updates;
3) Implementation of a Hazard Communication Program;
4) Training programs, including written procedures, for the transfer, management, and
disposal of significant materials;
5) Operator -attended transfers of petroleum products and other significant materials;
6) Trained emergency response personnel and written response procedures; and
7) Inspection, testing, and recordkeeping practices for AST's and other storage devices
including oil containing equipment and secondary containment.
Based on the types and quantities of materials used and stored at the Site, the Kinston
facility is subject to Emergency Planning and Community Right -to -Know Act (EPCRA)
requirements. The facility has a system in place for tracking chemicals on Site through
use of a chemical inventory. Chemical spills are addressed by the Site emergency
response team in accordance with the Site Chemical Emergency Response Plan.
The Site has also implemented a Spill Prevention, Control and Countermeasures (SPCC)
Plan. In addition, the plant has a Hazard Communication program that describes the
systems used to review and manage chemicals on the Site. Hazard communication
training is conducted on an annual basis by Unifi personnel. Hazard labeling is
conducted for the bulk storage containers at the Site.
In the event of a release, the facility has trained personnel and equipment available to
contain and clean-up minor volumes of oil. On -site equipment and materials include
spill kits, shovels, and sorbent materials (booms, pads, etc.) that may be used to dike,
contain, and remove minor releases.

i
The managers of oil storage areas are responsible for properly instructing their
personnel in the operation and maintenance of equipment to prevent the discharge of
oil, and applicable pollution control laws, rules, and regulations.
At a minimum, training is conducted annually or whenever new spill regulations are
promulgated, existing operating systems are modified, personnel responsibilities
change, or the SPCC Plan is amended. Attendance rosters and other training records
will be maintained in the main office for a period no less than three years.
In case of a larger release, specific response procedures have been developed. As part of
these procedures, internal and external resources (contractors) have been identified to
assist facility personnel. These contractors have the capabilities to provide emergency
response, industrial power vacuuming, building decontamination, excavation,
earthmoving, and waste transportation and disposal services.
Oil storage tanks and other storage devices including secondary containment are
regularly inspected, maintained, and tested for integrity. ASTs containing oil, chemicals,
and raw materials are subjected to quarterly inspections as detailed on the Quarterly
Fuel Oil Storage Tank Inspection Report and other documents. Quarterly inspections
include observations for tank, valve, and line conditions; blank and locked out valve
use; dike or wall conditions; operation of level indicators; leak or spill evidence;
overhead pipe and support conditions; and availability of sorbent material. Above
ground oil tanks are also subjected to periodic integrity testing, which includes
observations for leaks, and inspection of bolts, washer gaskets, welds, seam rivets, and
piping where practicable. Visual observations also include an inspection of the footings
for signs of settling.
Each oil storage container is also evaluated during the semi-annual dike inspection for
evidence of corrosion or deterioration. All above ground valves and pipelines are
regularly examined by operating personnel at which time the general conditions of
items such as flange joints, expansion joints, valve glands and bodies, catch pans,
pipeline supports, locking of valves, and metal surfaces are assessed. In addition
periodic pressure testing for pipes in areas where facility drainage is such that a failure
might lead to a spill event is performed if warranted.
Tank truck transfer lines and liquid level sensing devices are also tested regularly. All
inspections and test results are recorded as to dates, time, results, and corrective
maintenance. Any defective item is promptly corrected.
All oil storage dikes are inspected semi-annually in accordance with the Kinston Plant
Dike Inspection Checklist. Semi-annual inspections include visually assessing the

integrity of the walls, floor, seals, pumps, pipelines, and related appurtenances. The
position of each drain valve is confirmed to be in the closed position. Each oil storage
container is also evaluated during the semi-annual inspection for evidence of corrosion
or deterioration.
All outdoor tank dikes, with the exception of the main No. 6 fuel oil dike, must be
drained of rainwater periodically. Water will not be collected to a level that personnel
safety is jeopardized when entering a dike. Prior to draining a dike, the liquid will be
visually inspected for the presence of oil. If no oil or sheen is apparent, the dike may be
drained. If oil or sheen is present, the plant Environmental Group will be contacted for
instructions. Records of inspections and tests are kept with the SPCC Plan for a period
of 3 years.
The main No. 6 fuel oil tank (Tank 300) has an earthen dike, so any rainwater that enters
the dike percolates into the soil. Any spill or leakage is manually removed from the
diked area.
Facility -owned transformers are observed during work shifts by Power House
operations personnel. Observations of the transformers include corrosion, staining or
leaking. These inspection records are kept with the SPCC Plan. The five facility -owned
transformers are subjected to annual tests by an external contractor, and are overhauled
every 5 years.
The utility -owned oil -containing transformers and load tap changers are inspected every
5 years by Carolina Power and Light (Progress Energy) substation maintenance crews.
Inspections include looking for oil leaks, checking oil levels and testing the oil as
needed. Maintenance is performed on the load tap changer by the substation
maintenance crew every 3 years or 100,000 operations, whichever comes first.
Maintenance activities include checking oil levels, checking for leaks, and oil
replacement. Maintenance is performed on oil and gas circuit breakers once every six
months, or less as determined by other factors. Maintenance activities include removing
and replacing the oil from the breakers.
Solid wastes generated at the Site are segregated and stored primarily in bulk form in
dumpsters, open -top lugger boxes, drums, and tanks. Solid waste, currently
temporarily managed on Site, consists of the wastewater treatment plant sludge, which
is thin spread on the Site to dry, in accordance with the Site NPDES permit, prior to
transportation and disposal at the Waste Industries, Inc. landfill in Bertie County, North
Carolina. The remaining solid wastes are all transported off Site for disposal.

The Site is a Small Quantity Generator (SQG) of hazardous waste. It has been assigned
EPA ID #NCD 003 190 386. There is little hazardous waste generated from the
production processes. Most of the generated waste consists of fluorescent light bulbs
and miscellaneous wastes from maintenance, cleaning of vessels, decommissioning
activities, and laboratory operations. All hazardous wastes are packaged, labeled, and
transported off Site using manifests with third party licensed hazardous waste
transporters. The Site has a number of oil storage and satellite accumulation areas and
one 90-day hazardous waste accumulation area that is maintained in a secure location
away from the Site production areas.
Treatment Processes
The facility also conducts a variety of treatment processes as part of manufacturing
operations including wastewater treatment at the industrial wastewater treatment plant
(IWWTP) that discharges to Outfall 001. The IWWTP is authorized to discharge treated
process and sanitary wastewaters, remediated groundwater, leachate, and non -contact
cooling water from Outfall 001. Various treatment processes performed at the plant are
listed in the following table.
