Permit No. NC0005762
A(3.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 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 February, May, August, and
November. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent
discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below
the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that
does have a detectable impairment of reproduction or survival. The definition of "detectable impairment,"
collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase
II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
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 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.
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.

Permit No. NC0005762``
A(4.) COLOR REOPENER AND MONITORING REQUIREMENTS
This permit will be modified or revoked and reissued to incorporate color limitations an/or revised monitoring
requirements in the event color testing or other studies conducted by the permittee or the Division indicate that
color has rendered or could render the receiving waters injurious to public health, secondary recreation, to
aquatic life and wildlife or adversely affect the palatability of fish, aesthetic quality or impair the water for any
designated use.
In addition to the reopener, the permittee shall immediately report by telephone any observable instream color
at downstream (post discharge) monitoring points noted to be visually dissimilar to background (upstream
monitoring point). Upon discovery of an observable instream color difference, the permittee shall notify the
Division at either [phone] or 1-800-662-7959 (weekends & holidays). The notification shall indicate
the ADMI color units for upstream and downstream monitoring points and the observed color (hue) in the
receiving waters. Should downstream color become apparent (as observed by the Division) the permittee shall
immediately initiate corrective actions necessary to eliminate the color episode.
Information relayed by telephone shall also be filed by a written report in letter form within 5 days following
the first knowledge of the occurrence and also reported on the Discharge Monitoring Report (DMR) post
marked no later the 30th day following the completed reporting period.
Color monitoring should consist of ADMI monitoring as previously specified (see below). Effluent should be
monitored seven (7) days per week during the summer months (low flow period) and five (5) days per week
during the winter months. Upstream and downstream monitoring for color should be monitored 3/Week during
the months of June through September and 1/Week the remainder of the year (see Footnote 1 of Special
Condition A.1.).. Flow measurements at the WestPoint Stevens gage upstream of the intake should be recorded
at the time color samples are collected. Monitoring frequency is based on previous color episodes originating
during weekend discharges affecting downstream usage two days later — based on travel time of the river. All
samples taken should have complete descriptive recordings of the color in the sample container such as hue
(distinctive characteristics and tint), clarity (clearness of the color sample) and luminance (brightness or
glowing quality) of the sample as it looks in the collection container. Descriptions of stream color should also
be recorded as color samples are collected.
Color samples should be analyzed as follows:
a) at natural pH
b) free from turbidity (True Color); and
c) Using a narrow -band scanning spectrophotometer to produce a COMPLETE spectral curve
of the visible spectrum (350-750 nm). Calculate and report results in ADMI color units from
the information indicated
All color data, which includes visual observations, should be included with the monthly DMRs.
A(5.) COLOR NOTIFICATION REQUIREMENT
The Division of Water Quality — Fayetteville Regional Office, the City of City of Lumberton Water Treatment
Plant, and the Robeson County Water Treatment Plant shall be notified whenever WestPoint Stevens, Inc.
personnel observe an instream color level could adversely affect normal water treatment operations.

BACKGROUND
The WestPoint Stevens operates a 7.0 MGD facility for the treatment of wastewater from the
manufacture of yarn, weaving, dyeing, finishing, and carpet dyeing and manufacturing. The yarn
is used to make towels. The carpet dyeing and manufacturing is part of a separate production
performed in a building co joined with WestPoint Stevens (and the WestPoint Stevens WWTP
receives dye wastewater from the carpet manufacturer). DWQ personnel performed a site visit
on April 21, 2005 in conjunction with the permit drafting.
WestPoint Stevens also discharges cooling water from two outfalls into Big Shoe Heel Creek.
The Permittee has submitted Standard Forms 1 & 2C in order to request renewal of the permit
and has not requested any changes to the permit.
Recent data indicate that WestPoint is discharging below its current limits. The newly calculated
limits based on production data supplied with the permit renewal and federal guidelines indicate
some values above, and others below, the current permit limits. Because this discharge largely
operates below its current limits (for parameters based upon production, there have only been
three daily maximum violations in the past three years), and the discharge goes into HQW, no
change will be made to the current limits where higher limits are indicated, and current limits
will be adjusted where lower limits are indicated. The anti deg rule 15A NCAC 2B 0201(d) has
been applied to this renewal by allowing no increase in existing permitted loading.
Verification of Existing Conditions and DMR Data Review
This facility discharges to subbasin 03-07-51 in the Lumber River Basin, to receiving waters that
are classified HQW WS-IV B-Sw. All waters in this subbasin are considered impaired on an
evaluated basis because of fish consumption advice for mercury. DMR data from January 2002
through December 2004 were reviewed. This information is summarized in Attachment 1. A
review of the metals and toxicants was also performed. With the exception of total residual
chlorine (TRC), these are discussed in the Reasonable Potential Analysis section. TRC values
for the past three years have all been below detection level (20µg/1).
Fact Sheet
NPDES NC0005762 Renewal
Page 1

Instream Monitoring
This facility also collects instream data for temperature, conductivity, dissolved oxygen, and
color. These are sampled 3/week and are summarized in Attachments 2-6. Review of the data
indicates no significant issues downstream. Therefore, no changes are recommended.
Compliance
The Fayetteville Regional Office (FRO) conducted several site visits during this permit term to
evaluate compliance. A Staff Report was also prepared in conjunction with the permit renewal.
FRO finds the facility to be in compliance with the NPDES permit and recommends renewal.
Toxicity Testing
Current requirement: Chronic P/F @ 9%, based on 7 MGD flow. The facility has been in
compliance with its toxicity limit since its last renewal in 2000.
Proposed requirement: Chronic P/F @ 9%, based on 7 MGD flow.
PERMITTING STRATEGY
Tables 1 through 3 present limits calculations per subpart. Renewal limits are additive, i.e., a sum of
all subparts (see summation, Table 4). Under each subpart, the Division used the Average Daily
Production figures indicated on the application (lbs / day) to calculate both Daily Maximums and
Monthly Averages.

* The limit for Total Phenol has historically been based on water quality standards rather than effluent guidelines, as this
is more stringent. Limit (daily max) was developed using the WQ standard of 1 µg/I, 30Q2 of 220 cfs, and the effluent flow
of 7.0 MGD, with the weekly average limit given as the equivalent loading at 4.5 MGD.
Recommend permitting at the previous permit limits for all current parameters except COD.
Recommend permitting with calculated limits for COD as they are slightly lower than previous
limits. Recommend no parameters be added or deleted.
Reasonable Potential Analysis (RPA)
The Division conducted EPA -recommended analyses to determine the reasonable potential for
toxicants discharged by this facility to exceed water quality standards, based on DMR data from
2002 to 2004. Calculations included parameters listed in the previous permit to include:
chromium, phenol, copper, and zinc. Results suggest reasonable potential for the facility to
exceed allowable levels of phenol, so the current limits/monitoring requirements will remain.
Results suggest reasonable potential for copper and zinc to also exceed allowable levels.
However, these parameters are action level parameters, and the facility has not failed any toxicity
tests since the last permit renewal in 2000; therefore no limits will be given, but monitoring will
remain. Results suggest no reasonable potential to exceed allowable levels of chromium (and no
detects); therefore, the current quarterly monitoring requirement will remain unchanged in the
renewal.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the following will be incorporated into the permit:
• Reduction of COD limits based on current production data and 40 CFR
• Decrease of monitoring frequency from 2/month to monthly for copper and zinc due to the
fact that the facility has passed all toxicity tests in this permit term.
