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

A. (3.) CHRONIC TOXICITY MONITORING/LIMIT — O.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, quarterlu 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 valu for multiple concentration tests will be determined using the geometric mean of the
highest concentr tion 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 testin results required as part of this permit condition will be entered on the Effluent
Discharge Monit ring Form (MR-1) for the months in which tests were performed, using the
parameter code GP3B for the pass/fail results and THP3B 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

1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water 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 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 Mast 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) Annial Mass Loading (lb/yr) = E (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 ha 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 2H.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 egulations 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):

Monitoring Report (eDMR) interne application.
Page 7 of 9

Permit NC0004812
Monitoring results obtained during the previous month(s) shall be summarized for each month
and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the
state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
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 of 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 last day of the month following
the commencement of discharge.
2. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B. (11.)

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be
representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days. These samples shall be representative of
the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which is
not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or
(3)
Version 11/09/2011

NPDES Permit Standard Conditions
Page 2 of 18
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
> Influent samples shall not be collected more than once per hour.
> Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.
> Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWQ or "the Division"
The Division of Water Quality, Depailinent of Environment and Natural Resources.
Effluent
Wastewater discharged following all treatment processes from a water pollution control facility or other point source
whether treated or untreated.
EMC

EPA
The United States Environmental Protection Agency
Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Version 11/09/2011

Instantaneous flow measurement
The flow measured during the minimum time required for the flow measuring device or method to produce a result in
that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab
samples required for the same sampling period so that together the samples and flow are representative of the discharge
during that sampling period.
Monthly Average (concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal
coliform or other bacterial parameters or indicators, the geometric mean of such discharges.
Permit Issuing Authority

approved under 40 CFR 136, unless otherwise specified in 40 CFR 503, unless other test procedures have been
specified in this permit [40 CFR 122.41].
To meet the intent of the monitoring required by this permit, all test procedures must produce minimum detection
and reporting levels that are below the permit discharge requirements and all data generated must be reported down
to the minimum detection or lower reporting level of the procedure. If no approved methods are determined
capable of achieving minimum detection and reporting levels below permit discharge requirements, then the most
sensitive (method with the lowest possible detection and reporting level) approved method must be used.
5. Penalties for Tampering
The CWA provides that any person who falsifies, tampers with, or knowingly renders inaccurate, any monitoring
device or method required to be maintained under this permit shall, upon conviction, be punished by a fine of not
more than $10,000 per violation, or by imprisonment for not more than two years per violation, or by both. If a
conviction of a person is for a violation committed after a first conviction of such person under this paragraph,
punishment is a fine of not more than $20,000 per day of violation, or by imprisonment of not more than 4 years,
or both [40 CFR 122.41].

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and (j) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
(3)
(5)
(7)
(8)
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Permittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the
investigation into possible sources; the period of the discharge, including exact dates and times; if the
discharge has not ceased, the anticipated time it is expected to continue; and steps taken or planned to reduce,
eliminate, and prevent reoccurrence of the noncompliance,

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 quality in 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 Yam 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 02/01/2009 through 02/01/2014. Facility has a very
negative compliance record (please see attached).
Pharr Yarns lias 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.
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 instream 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 specify that, if a state does not establish a system to receive such submittals, then permittees
must subilnit DMRs electronically to the Environmental Protection Agency (EPA). The Division
anticipates that these regulations will be adopted and is beginning implementation.
The requ}rement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) interne application has been added to the permit.

Actual treatment capacity of current facility (current design capacity): 1.0

e. Description of existing or substantially constructed WWT facilities: The existing
WWT facilities consist of an influent bar screen with pH control (sodium hydroxide)
followed by an aeration basin with fixed floating aerators, polymer and alum addition,
two (2) clarifiers, defoamer and sodium hypochlorite addition, flow measurement
(continuous flow recording device with totalizer), three (3) mixed media pressure
filters, a sludge thickening tank, an aerobic sludge digester, a sludge centrifuge, a belt
filter press, tablet chlorine disinfection with dual chlorine contact basins, and
dechlorination.
PART III - OTHER PERTINENT INFORMATION
1. Special monitoring or limitations (including toxicity) requests: None at this time.
PART IV - EVALUATION AND RECOMMENDATIONS
Pharr Yarns (PY) requests renewal of the subject Permit. There have been no changes to the
existing WWT facility or the NPDES permit since the permit was last renewed.
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.

SLUDGE MANAGEMENT PLAN
Pharr Yarns runs a one million gallon per day activated sludge wastewater treatment
plant. Sludge generated in the plant is controlled by doing daily settleability tests, sludge
blanket checks on the clarifier(s), and weekly MLSS tests. The sludge is wasted as
needed to one million gallon aerobic digester. The digested sludge is then land applied
to farm lan under permit No. WQ0035988 by Southern Soil Builders.
