Dear Mr. Davis:
Division personnel have reviewed and approved your application for a renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued
pursuant to the requirements- of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated October
15, 2007 (or as subsequently amended).
It is the Division's understanding that Pharr Yarns has entered into a contractual
agreement with the City of Gastonia to pump all of the nffs wastewater into the City's
collection system. This effort is anticipated to be completed during this permit term. Please
contact the Division to request permit rescission following connection.
The following changes have been incorporated into this renewal:
• Limits for BOD, COD, TSS, Sulfide, Phenols, and Total Chromium have been
recalculated based on the most recent production data in the permit application.
• Proposed federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and specify that, if a state does not establish a system to receive such -submittals, then
permittees must submit DMRs electronically to the Environmental Protection Agency (EPA).
The Division anticipates that these regulations will be adopted and is beginning
implementation.
The requirement to begin reporting discharge monitoring data electronically using the NC
DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added
to your final NPDES permit. [See Special Condition A. (7.)] For information on eDMR,

A. (3.) CHRONIC TOXICITY MONITORING/LIMIT — 0.5-MGD
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 0.62%.
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 THP313 for the Chronic Value. Additionally, DWR
Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621

30 days after the end of the reporting period for which the report is made.
ti
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 Water 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 Resources indicate potential impacts to the receiving stream,
this permit may be re -opened and modified to include alternate monitoring requirements or limits. If`
the Permittee monitors any pollutant more frequently then required by this permit, the results of
such monitoring shall be included in the calculation & reporting of the data submitted on the"DMR &
all AT Forms submitted.
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 NC0004812
A.(5.) TOTAL NITROGEN AND PHOSPHORUS MONITORING
The Permittee shall calculate the annual mass loading of total nitrogen as the sum of monthly
loadings, according to the following equations:
(a) Monthly Mass Loading (lb/mo.) = TN/TP x Q x 8.34
where: TN = the average total nitrogen concentration (mg/ L) of the
composite samples collected during the month at the
outfall
TP = The average total phosphorus concentration (mg/L) of the
composite samples collected during the month at the
outfall
Q = the total wastewater flow discharged during the month at
the outfall(MG/mo.)
8.34 = conversion factor, from (mg/L x MG) to pounds
(b) Annual Mass Loading (lb/yr) = Y_ (Monthly Mass Loadings) for the calendar year
The Permittee shall report the total nitrogen and total phosphorus concentration for each sample
and the monthly mass loading in the appropriate self -monitoring report and the annual mass
loading of total nitrogen and total phosphorus in the December self -monitoring report for the
year.
A. (6.) COLOR PERMITTING REQUIREMENTS FOR TIER I FACILITY
This facility has been classified as a Tier 1 color discharger. The permittee will conduct color
monitoring of instream stations (upstream, downstream) on a monthly basis during summer season
(April -October). The permittee will record whether a color plume was observed around the outfall
pipe during the monthly, instream sampling events, and include that information on the monthly
discharge monitoring report. Effluent samples will be collected monthly for color on a year-round
basis. Color samples will be analyzed for ADMI color at natural pH. Effluent samples will consist of
24-hour composites, while instream samples will be collected as grabs. Samples will be analyzed by
a state certified laboratory.
If data show that water quality standards for color are being violated by the discharge permitted by
the terms of this permit, then the Director may reopen this permit for the purpose of imposing
additional requirements pursuant to 15A NCAC 211.0114. Alternatively, if future conditions change
and color is no longer a component of the influent wastestream, then the permittee may request a
permit modification to remove color permit requirements:
A. (7.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees
must submit DMRs electronically to the Environmental Protection Agency (EPA). The Division
anticipates that these regulations will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):

ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 21699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1,
1.1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be
submitted to the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date
the facility would be required under this permit to begin using eDMR. Temporary waivers shall
be valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be
submitted electronically to the Division unless the permittee re -applies for and is granted a new
temporary waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http: / /portal.ncdenr.org/web/wq/admin/bog/ipu/edmr
Regardless bf the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the'1last day of the month following

BACKGROUND
Pharr Yarns, Inc. WWTP treats industrial waste created at the McAdenville facility as well as domestic
waste from three Pharr Yarns plants (including the McAdenville plant). The domestic waste from the
three Pharr Yarns plants constitutes the majority (73%) of the wastestream, the remainder is process
wastewater from the yarn dying that occurs at the McAdenville plant.
As a discharger to the South Fork Catawba River, the facility is subject to the'nutrient limits and special
monitoring requirements pertaining to color in an effort to improve water qualityin that receiving stream.
TECHNOLOGY BASED EFFLUENT LIMIT DEVELOPMENT
Reasonable measure of actual production for the facility was established based on the EPA policy
(15,618 lb/day). BOD5, COD, and TSS are based on effluent guidelines (40 CFR 410.70 Subpart G Stock
and Yarn Finishing Subcategory) and have been recalculated to reflect the most current data available
(See attached spreadsheet). COD allocation for domestic wastewater component was calculated using
the formula 2.2 X BOD. The 2.2 multiplier was established during the permit renewal in 2000 using site -
specific factors and Best Professional Judgment.
The results of these calculations are slightly different than the limits in the current permit. Since the
facility has no plans to expand production in the foreseeable future (per the facility), it is recommended
that the new limits be implemented. In August 2013, Pharr yarns entered into a contractual agreement
with the City of Gastonia to pump all of the mill's wastewater into the city's collection system. The
project is estimated to be completed within 2 years.
TOXICITY TESTING
Current Requirement: Quarterly Chronic Toxicity @ 0.62%/1.2% JAN, APR, JUL, OCT
Recommended Requirement: Quarterly Chronic Toxicity @ 0.62%/1.2% JAN, APR, JUL, OCT. The
facility has been consistently passing its WET tests (please see attached).

COMPLIANCE SUMMARY
DMRs have been reviewed for the period from
negative compliance record (please see attached).
02/01/2009 through 02/01/2014. Facility has a very
Pharr Yarns has had operator and equipment issues and problems with slug loads (with high BOD) being
discharged into the plant's influent. They have changed over to a liquid chlorination system but fecal
violations continued. They requested a technical assistance visit, which was performed during the
summer of 2009. They have hired an engineering firm to go through the entire plant and discussed
making modifications to the plant. MRO has previously met with Pharr Yarns staff to discuss these
issues and the numerous limit violations. The facility has an EPA Administrative Order to bring the
facility into compliance. The decision to connect to the POTW should alleviate the existing compliance
issues. I.
INSTREAM MONITORING
The facility is required to conduct self -monitoring of the South Fork Catawba River at one location
upstream of the discharge and one location downstream of the discharge. The instrearn self -monitoring
includes: fecal coliform, temperature, conductivity, color and dissolved oxygen. An analysis of DO,
temperature and conductivity showed that the facility have negligible negative impact on the receiving
stream.
REASONABLE POTENTIAL ANALYSIS
Reasonable potential analysis was conducted for Chromium and Phenols at 0.5 MGD and 1.0 MGD
(please see attached). Based on RPA, no water quality based limits are recommended.
PROPOSED CHANGES
• Limits for BOD, COD, TSS, Sulfide, Phenols, and Total Chromium have been recalculated
based on the most recent production data in the permit application.
• Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specifythat, if a state does not establish a system to receive such submittals, then permittees
must submit DMRs electronically to the Environmental Protection Agency (EPA). The Division
anticipates that these regulations will be adopted and is beginning implementation.
The requirement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application has been added to the permit.

In August, Pharr Yarns entered into a contractual agreement with the City of Gastonia (the
City) to pump all of the Mill's wastewater into the City's collection system. Officials with Pharr
Yarns estimate it will take 18 — 24 months for the design, approval, and construction -of the
infrastructure necessary to make this connection complete. Phar Yarns had hoped that they could
partner with the Town of McAdenville on this venture, but negotiations broke down between the Mill
and the Town, so the Mill chose to move forward alone.
Pending receipt and approval of the WLA, it is recommended that the Permit be renewed as
requested.
