Division personnel have reviewed and approved your request for modification 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 Statutes 143-215.1 and the Memorandum of Agreement between North
Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as subsequently amended).
Based on effluent guidelines from 40 CFR 410.70 Subpart G and a monthly average production value of
24000 lb/day (which will be used in the calculation of both daily maximum and monthly average limits), the
revised limits are as follows:
• Sulfide = 2.9 lbs/day (Monthly average); 5.8 Ibs/day (Daily maximum)
• Phenol =1.4 Ibs/day (Monthly average); 2.9 Ibs/day (Daily maximum)
• Total Chromium = 1.4 Ibs/day (Monthly average); 2.9 Ibs/day (Daily maximum)
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days
following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of
the North Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service
Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and
binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Quality or permits required
by the Division of Land Resources, the Coastal Area Management Act or any other Federal or Local

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 T14P313 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

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 (pounds/month) =. 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 otitfall
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/ month)
8.34 = conversion factor, from (mg& x MG) to pounds
(b) Annual 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 1 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 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.

BASIS FOR PERMIT MODIFICATION
Pharr Yarns has requested that the limits for sulfide, phenols, and total chromium that were assigned in
the January 21, 2005 permit be reevaluated. A review of the spreadsheet used in calculating limitations
based on plant production data and effluent guidelines from 40 CFR 410.70 Subpart G STOCK AND
YARN FINISHING SUBCATEGORY shows that limits were assigned based on only a percentage of plant
process flow. The correct effluent limits for sulfide, phenols and total chromium, while calculated on the
attached spreadsheet, were not assigned in the 2005 permit. This abbreviated fact sheet recommends a
modification in the limits for the three parameters. The previous permit writer had conferred with EPA
about the monthly average production value that should be used and it was decided that 24000 pounds
per day would be appropriate for calculation of daily maximum and monthly average limits. This
modification is to apply the appropriate limits as calculated by effluent guidelines. The correct limits
are listed below and all limits should be in lbs/day

CHANGES TO THE PERMIT
Revised limits for sulfide, phenols and total chromium will be given based on monthly
average production value of 24000 lbs/day projected for 2005. This monthly average
production number was used to calculate both the monthly average and daily maximum
limits. There should be no adjustment for percentage of process flow. The revised limits
will be higher than those given in 2005 permit.
COMPARING WATER QUALITY LIMITS AND EFFLUENT LIMITATION GUIDELINE (ELG)
Reasonable potential analysis (RPA) was performed for sulfide, chromium and phenol at both the outfall
in North Carolina waters and at the State line in South Carolina waters. The RPA at the borderline was
based on a very conservative estimate of the summer 7Q10 (223 cfs) of the South Fork Catawba River.
See the attached RPA spreadsheet for details.
The Tables below compare water quality limits in both States to the effluent limitation guideline, and the
most stringent limits of the two are applied in this permit with the exception of the SC standard and the
corresponding allowable for sulfide. The comparative limits in Tables 3-6 are all in mg/L.

Sulfide — NC has no water quality standard so ELG limit will be protective in NC. In regards to SC water
quality standards, there will likely be no presence of sulfide at the NC/SC State line, assuming
dissipation of sulfide and also taking into account 8.5 miles distance from the outfall to the State line.
Total Chromium — Both NC and SC water quality standards are less stringent than the ELG limit
so ELG limit is applied in this permit.
Phenol — NC has no water quality standard for phenol. SC's standard is above the ELG so ELG
limit is applied in this permit.
The Division of Water Quality has determined that the increased limits will not result in
contravention of applicable water quality standards or loss of the river's designated uses. An
alternative analysis was not performed because there was no increase in wasteflow or change in
the effluent characteristics from the facility.
Due to the stringency of the limits, the instream waste concentration of 0.62 % under 7Q10
conditions and the discharge point 8.5 miles above the month of the South Fork Catawba River
before its confluence into the Catawba River, DWQ does not believe that the discharge of
sulfide, phenols or total chromium. from Pharr Yarns will affect the water quality in South
Carolina. The distance to the NC/SC'State line and the amount of stream flow makes it unlikely
that the SC standards for these parameters will be violated.
WHOLE EFFLUENT TOXICITY (WET) TEST
Type of Toxicity Test: Chronic-P/F, (Quarterly)
Existing Limit: 001: Chronic P/F @ 0.62%
Recommended Limit: 001:, Chronic. P/F @ 0.62%
Monitoring Schedule: January, April, July, and October.
The permittee has passed all of the nineteen WET tests from January 2002 to July 2006. See the
attached WET testing summary.
CONCLUSION
Pharr Yarns, Inc., an embattled textile industry has done an excellent job passing all its toxicity
tests for the past four years. Sulfide will likely not be considered parameter of concern at the
State line where instream waste concentration (IWC) is 0.35% because at the outfall where IWC
is 0.62%, there is no indication of toxicity problem.
Research indicates that when soluble sulfide is discharged into water, it readily reacts with
hydrogen ions and dissociates into equal forms of HS and HZS at pH 7 (NAS 1974). The fact that
HzS is oxidized in well -aerated water by natural biological systems to sulfates or is biologically
oxidized to elemental sulfur has caused investigators to minimize the toxic effects of HZS on fish
and other aquatic life (Quality Criteria for Water, July 1976).
Based on the above theory and the fact that the permittee. has passed all its toxicity tests at the
outfall and assuming dissipation of sulfide, also considering that the discharge has to be
transported 8.5 miles from the outfall to the State line, NC strongly believes that sulfide will
most likely not be detected at the State line.

CC: Susan Wilson <[e-mail]>
Melinda, ,
Pharr Yarns WWTP's permit modification has been re -assigned to
Nowell had to go on medical leave. We apologize for the delay
in addressing SC concerns on this modification. I will like to
to address all your concerns so that the permit can be issued
delays.
me because Jackie
take this opportunity
without further
Just a recap of the key issues with this permit, NC DWQ issued a permit to Pharr
Yarns, Inc. in January 2005 with miscalculated limits which were developed from 40
CFR Part 410.10 Subpart G. The permittee was issued civil penalties and after further
review of the limits we�realized the error. The permit was then drafted with the
correct permit limits, noticed and EPA approved the draft. SC had concerns about the
new limits as to whether it would protect SC waters.
Based on a very conservative estimate of the summer 7Q10 (223 cfs) of the South Fork
Catawba River at the NC/SC border line with a discharge flow of 0.5 MGD,
approximately 8.5 miles from the outfall, a reasonable potential analysis was
performed for sulfide, chromium and phenol using SC water quality standards.
Considering all the variables involved in this situation, NC believes that SC waters
will be protected (See data for details). Although the permit includes an effluent
limitation page for 1.0 MGD, NC believes that the permittee will never reach that
capacity within this permit cycle based on the last two years effluent data and the
known volatility history of textile industry. See the attachment for all the data
used.
Please let me have your comments as soon as possible (preferably by Nov. 24th). For
your convenience, we will be happy to schedule a conference call with you if you
like. If no comment is.received by the said.date, we will move forward with a final
permit. Thanks a lot for your cooperation on this matter. If you have any questions,
please feel free to give me a call at [phone] ext. 508 or you can always reach
me by an email. Thanks a lot.

Footnotes:
A This water quality criterion was derived from data for arsenic (III), but is applied here to total arsenic, which might imply that arsenic (III) and arsenic (V) are equally toxic to aquatic life and that their toxicities are
additive. In the arsenic criteria document (EPA 440/5-84-033, January 1985), Species Mean Acute Values are given for both arsenic (III) and arsenic (V) for five species and the ratios ofthe SMAVs for each species
range from 0.6 to 1.7. Chronic values are available for both arsenic (III) and arsenic (V) for one species; for the fathead minnow, the chronic value for arsenic (V) is 0.29 times the chronic value for arsenic (III). No
data are known to be available concerning whether the toxicities of the forms of arsenic to aquatic organisms are additive.
B This criterion has been revised to reflect The Environmental Protection Agency's ql * or RfD, as contained in the Integrated Risk Information System (IRIS) as of May 17, 2002. The fish tissue bioconcentration factor
(BCF) from the 1980 Ambient Water Quality Criteria document was retained in each case. -
C This criterion is based on carcinogenicity of 10-6 risk. As prescribed in Section E of this regulation, application of this criterion for permit effluent limitations requires the use annual average flow or comparable tidal
condition as determined by the Department.
D Freshwater and saltwater criteria for metals are expressed in terms of total recoverable metals. As allowed in Section E of this regulation, these criteria may be expressed as dissolved metal for the purposes of deriving
permit effluent limitations. The dissolved metal water quality criteria value may be calculated by using these 304(a) aquatic life criteria expressed in terms of total recoverable metal, and multiplying it by a conversion
factor (CF). The term "Conversion Factor" (CF) represents the conversion factor for converting a metal criterion expressed as the total recoverable fraction in the water column to a criterion expressed as the dissolved
fraction in the water column. (Conversion Factors for saltwater CCCs are not currently available. Conversion factors derived for saltwater CMCs have been used for both saltwater CMCs and CCCs). See "Office of
Water Policy and Technical Guidance on Interpretation and Implementation of Aquatic Life Metals Criteria", October 1,1993, by Martha G. Prothro, Acting Assistant Administrator for Water, available from the Water
Resource center, USEPA, 401 M St., SW, mail code RC4100,Washington, DC 20460; and 46CFR§ 131.36(b)(1). Conversion Factors can be found in Attachment 1 — Conversion Factors for Dissolved Metals.
E The freshwater criterion for this metal is expressed as a function of hardness (mg/L) in the water column. The value given here corresponds to a hardness of 25 mg/L as expressed as CaCO3. Criteria values for other
hardness may be calculated from the following: CMC (dissolved) = exp{mA [ln(hardness)]+ bA) (CF), or CCC (dissolved) = exp{mc [In (hardness)]+ bc) (CF) and the parameters specified in Attachment 2 —
Parameters for Calculating Freshwater Dissolved Metals Criteria That Are Hardness -Dependent. As noted in footnote D above, the values in this appendix are expressed as total recoverable, the criterion may be
calculated from the following: CMC (total) = exp{mA [In( hardness)]+ bA), or CCC (total) = exp{mc [In (hardness)]+ bc).
F Freshwater aquatic life values for pentachlorophenol are expressed as a function of pH, and are calculated as follows: CMC = exp(1.005(pH)-4.869); CCC = exp(1.005(pH)-5.134). Values displayed in table
correspond to a pH of 7.8.
G This criterion is based on 304(a) aquatic life criterion issued in 1980, and was issued in one of the following documents: Aldrin/Dieldrin (EPA 440/5-80-019), Chlordane (EPA 440/5-80-027), DDT (EPA 440/5-80-
038), Endosulfan (EPA 440/5-80-046), Endrin (EPA 440/5-80-047), Heptachlor (440/5-80-052), Hexachlorocyclohexane (EPA 440/5-80-054), Silver (EPA 440/5-80-071).. The Minimum Data Requirements and
derivation procedures were different in the 1980 Guidelines than in the 1985 Guidelines. For example, a "CMC" derived using the 1980 Guidelines was derived to be used as an instantaneous maximum. If assessment
is to be done using an averaging period, the values given should be divided by 2 to obtain a value that is more comparable to a CMC derived using the 1985 Guidelines.
H No criterion for protection of human health from consumption of aquatic organisms excluding water was presented in the 1980 criteria document or in the 1986 Quality Criteria for Water. Nevertheless, sufficient
information was presented in the 1980 document to allow the calculation of a criterion, even though the results of such a calculation were not shown in the document.
I This criterion for asbestos is the Maximum Contaminant Level (MCL) developed under the Safe Drinking Water Act (SDWA) and the National Primary Drinking Water Regulation (NPDWR).
J EPA has not calculated a 304(a) human health criterion for this contaminant. The criterion is the Maximum Contaminant Level developed under the Safe Drinking Water Act (SDWA) and the National Primary .
Drinking Water Regulation (NPDWR). 44

K This criterion is based on a 304(a) aquatic life criterion that was issued in the 1995 Updates: Water Quality Criteria Documentsfor the Protection ofAquatic Life in Ambient Water, (EPA-820-B-96-001, September
1996). This value was derived using the GLI Guidelines (60FR 15393-15399, March 23, 1995; 40CFRI32 Appendix A); the difference between the 1985 Guidelines and the GLI Guidelines are explained on page iv of
the 1995 Updates. None of the decisions concerning the derivation of this criterion were affected by any considerations'that are specific to the Great Lakes.
L The CMC=1/[(f7/CMC 1) + (f2/CMC2)] where fl and f2 are the fractions of total selenium that are treated as selenite and selenate, respectively, and CMC 1 and CMC2 are 185.9 µg /1 and 12.82 ug /l, respectively.
M This criterion applies to total PCBs, (e.g., the sum of all congener or all isomer or homolog or Aroclor analyses.)
N The derivation of the CCC for this pollutant did not consider exposure through the diet, which is probably important for aquatic life occupying upper trophic levels.
O This state criterion is also based on a. total fish consumption rate of 0.0175 kg/day.
P This water quality criterion is expressed as Ecg free cyanide (as CN)/L.
Q This value was announced (61 FR58444-58449, November 14, 1996) as a proposed GLI 303 I aquatic life. criterion
R This water quality criterion for arsenic refers to the inorganic form only.
S This water quality criterion for selenium is expressed in terms of total recoverable metal in the water column. It is scientifically acceptable to use the conversion factor (0.996 - CMC or 0.922- CCC) thatwas used in
the GLI to convert this to a value that is expressed in terms of dissolved metal.
T The organoleptic effect criterion is more stringent than the value for priority toxic pollutants.
U This value was derived from data for heptachlor and the criteria document provides insufficient data to estimate the relative toxicities of heptachlor and heptachlor epoxide.
V There is a full set of aquatic life toxicity data that show that DEHP is not toxic to aquatic organisms at or below its solubility limit.
W This value was derived from data for endosulfan and is most appropriately applied to the sum of alpha-endosulfan and beta-endosulfan.
X This criterion is based on a 304(a) aquatic life criterion issued in 1980 or 1986, and was issued in one of the following documents: Aldrin/Dieldrin (EPA440/5-80-019), Chlordane (EPA 440/5-80-027), DDT (EPA
440/5-80-038), Endrin (EPA 440/5-80-047), Heptachlor (EPA 440/5-80-052), Polychlorinated Biphenyls (EPA 440/5- 80-068), Toxaphene (EPA 440/5-86-006). This CCC is based on the Final Residue value
procedure in the 1985 Guidelines. Since the publication of the Great Lakes Aquatic Life Criteria Guidelines in 1995 (60FR15393-15399, March 23, 1995), the EPA no longer uses the Final Residue value procedure for
deriving CCCs for new or revised 304(a) aquatic life criteria.
Y This water quality criterion is based on a 304(a) aquatic life criterion that was derived using the 1985 Guidelines (Guidelines for Deriving Numerical National Water Quality Criteria for the Protection ofAquatic
Organisms and Their Uses, P1385-227049, January 1985) and was issued in one of the following criteria documents: Arsenic (EPA 440/5-84-033), Cadmium (EPA 440/5-84-032), Chromium (EPA 440/5-84-029),
Copper (EPA 440/5-84-031), Cyanide (EPA 44015-84-028), Lead (EPA 440/5-84-027), Nickel (EPA 440/5-86-004), Pentachlorophenol (EPA 440/5-86-009), Toxaphene, (EPA 440/5-86-006), Zinc (EPA 440/5-87-
003).
Z When the concentration of dissolved organic carbon is elevated, copper is substantially less toxic and use of Water -Effect Ratios might be appropriate.
as The selenium criteria document (EPA 440/5-87-006, September 1987) provides that if selenium is as toxic to saltwater fishes in the field as it is to freshwater fishes in the field, the status of the fish community should
be monitored whenever the concentration of selenium exceeds 5.0 µg/L in salt water because the saltwater CCC does not take into account uptake via the food chain.
bb This water quality criterion was derived on page 43 of the mercury criteria document (EPA 440/5-84-026, January 1985). The saltwater CCC of 0.025 ug/L given on page 23 of the criteria document is based on the
Final Residue value procedure in the 1985 Guidelines. Since the publication of the Great Lakes Aquatic Life criteria Guidelines in 1995 (60FR15393-15399, March 23, 1995), the EPA no longer uses the Final Residue
value procedure for deriving CCCs for new or revised 304(a) aquatic life criteria.
cc This water quality criterion was derived in Ambient Water Quality Criteria Saltwater CopperAddendum (Draft, April 14, 1995) and was promulgated in the Interim Final National Toxics Rule (60FR22228-222237,
May 4, 1995).
dd This water quality criterion was derived from data for inorganic mercury (II), but is applied here to total mercury. If a substantial portion of the mercury in the water column is methylmercury, this criterion will
probably be under protective. In addition, even though inorganic mercury is converted to methylmercury and methylmercury bioaccumulates to a great extent, this criterion does not account for uptake via the food
chain because sufficient data were not available when the criterion was derived.
ee This criterion is a noncarcinogen. As prescribed in Section E of this regulation, application of this criterion for determining permit effluent limitations requires the use of 7Q10 or comparable tidal condition as
determined by the Department.
ff EPA is currently reassessing the criteria for arsenic.
gg This criterion applies to DDT and its metabolites (i.e., the total concentration of DDT and its metabolites should not exceed this value).
hh Although a new RfD is available in IRIS, the surface water criteria will not be revised until the National Primary Drinking Water Regulations: Stage 2 Disinfectants and Disinfection Byproducts Rule (Stage 2 DBPR) is
completed, since public comment on the relative source contribution (RSC) for chloroform is anticipated. -
ii Although EPA has not published a completed criteria document for phthalate, it is EPA's understanding that sufficient data exist to allow calculation of aquatic life criteria.

Subject: Re: Fw: a conf call on mon or tues
From: "Melinda Vickers" <[e-mail]>

To: <[e-mail] gov>, <[e-mail]>
Sorry, I was out yesterday. I have a meeting this morning (Tues) from 9-10.
Any time this afternoon work? I am open all day tomorrow (wed).
Here is a basic summary of what I need to see so Jackie can be thinking about it:
I was looking for the DMR data (basically the highest sample ever recorded) so I could
check into reasonable potential for chromium and sulfide. We have water quality
standards for both of these parameters that I wanted to compare to the guidelines
values to determine if the WQ limits are more stringent and to see if reasonable
potential exists. It appears that our sulfide WQ limits would be slightly more
restrictive than the guidelines.
Also, the limits derived for guidelines are much higher than the previous permit
limits. No justification was given for backsliding or any info on an antidegradation
review being performed to allow an increase in the limits.
See the attached spreadsheet for a summary of the values that I am using to make these
comparisons.

Back on June 16, I had asked Jackie Nowell for some DMR data so I could evaluate
sulfide,'chromium and phenols (I copied you on that email). It appeared from the
fact sheet that the SC WQ standards for these parameters were not considered (or if
they were, there was no indication of such) and I wanted to see whether RP exists or
not and what the derived WQ limits would be in comparison to the categorical limits.
It appeared that only the categorical guidelines were limited. I never got a reply
to my request from NC.
Maybe this is something you have evaluated in your review, but there was nothing in
what I was given to indicate such. I hope the permit has not moved forward. If it
has been issued, I would like to see the final version of the -permit and know the
appeal period for the permit. SC would be concerned if there were not limits
protective of water quality in the permit.

Hello Marshall,
We did not receive another request for DMR data from SCDHEC (Susan
asked you to mediate that request in a 6/16 email.) If you have not
gotten a response from them on your email, I am going to move forward
with finalizing the Pharr Yarns permit mod since you all have signed off

Re: NC0004812 Pharr Yarns effluent pages
have a water quality standard for sulfide, so the effluent guideline
limit that is given should be protective of the stream. The allowable
concentrations for phenols and chromium from the NC standards are less
stringent that the effluent guideline limits that are given. The limits
assigned in the permits from 1977 through 1996 were less stringent than
the limits that will be assigned in this modification.
1996 limits
2006 limits
Mon. Avg. Da. Max.
Mon. Avg. Da. Max.
sulfide 4.6 lbs/day 11.8 lbs/day
2.9 lbs/day 5.8 lbs/day

1.4 lbs/day 2.9 lbs/day
Total Chromium 2.9 lbs/day 5.9 lbs/day 1.4
lbs/day 2.9 lbs/day
An antidegradation statement can be added to the factsheet that states
that The Division of Water Quality has determined that the increased
limits will not result in contravention of applicable water quality
standards or loss of the river's designated uses. An alternatives
analysis was not performed because there was no increase in wasteflow or
change in the effluent characteristics from the facility.
Due to the stringency of the limits, the instream waste concentration of
0.6 % under 7Q10 conditions and the discharge point 8.5 miles above the
mouth of the South Fork Catawba River before its confluence into the
Catawba River, DWQ does not believe that the discharge of sulfide,
phenols or total chromium from Pharr Yarns will effect the water
quality in SC. The distance to the NC/SC state line and the amount of
stream flow makes it unlikely that the SC standards for these parameters
will be violated.
Please contact me if there are any additional questions.

Michael, per the request in the April 27 letter from Mihir Mehta
regarding the subject facility. The permit modification is for the
revision of limits for sulfide, phenols, and total chromium based on
effluent guidelines for 40 CFR 410.70 Stock and Yarn Finishing Subcategory.
Attached is the draft cover letter, draft permit and factsheet for Pharr
Yarns. Pharr Yarns discharges into the South Fork Catawba River with a
7Q10 of 125 cfs and an average flow of 808 cfs. At 0.5 MGD, Pharr
Yarns has an instream waste concentration of 0.6 % . At the expansion
flow of 1 MGD, the instream waste concentration is 1.2 8. The distance
from the discharge point to the mouth of the South Fork Catawba River
where it enters the Catawba River is approximately 8.5 miles. North
Carolina has an action level standard for copper of 7 ug/l and the
allowable copper concentrations for Pharr Yarns at the end of pipe would
be 1136 ug/1 at 0.5 MGD and 572 ug/l at 1.0 MGD.
If the SC standard for copper of 2.9 ug/1 is applied, the allowable
concentration for copper at 0.5 MGD is 471 ug/l, and at 1.0 MGD, the
allowable concentration for copper is 237 ug/l. There was one value for
copper of 41 ug/l reported in the pollutant analysis done in Dec. 2004.
This data value is substantially less than the allowable concentrations
and would seem to indicate that copper is not a pollutant of concern for
Pharr Yarns. In addition, Pharr Yarns has consistently passed its whole
effluent toxicity test.
Regarding fecal coliform, the recommended and
the Pharr Yarns permit are 200/100ml (monthly
(daily maximum). Please contact me if there

Marshall - I'll talk to Melinda is necessary - but this really smacks of a lack of trust (it's starting to hurt
our feelings) and we don't really think it's necessary to provide them with this. Jackie was correct - there
is such an amount of dilution prior to the state line - that it shouldn't be an issue anyway. The other
thing is - we screwed up the permit before and we need to get it corrected (and we've gone through all
the proper .procedure to do so).
So - could you mediate this one a bit?
thanks!

apologize about the deletion of the effluent pages, I forgot that the

The limits for sulfide, phenols, and total chromium were revised by DWQ
after it was determined that the limits for these parameters were
incorrectly reduced during calculations from the effluent guidelines.
There was no increase in wasteflow from the facility or changes in
production to stimulate the limits revision. This is a correction of
our calculation and EPA has reviewed and approved the modification.

BASIS FOR PERMIT MODIFICATION
Pharr Yams has requested that the limits for sulfide, phenols, and total chromium that were assigned in
the January 21, 2005 permit be reevaluated. A review of the spreadsheet used in calculating limitations
based on plant production data and effluent guidelines from 40 CFR 410.70 Subpart G STOCK AND
YARN FINISHING SUBCATEGORY shows that limits were assigned based on only a percentage of plant
process flow. The correct effluent limits for sulfide, phenols and total chromium, while calculated on the
attached spreadsheet, were not assigned in the 2005 permit. This abbreviated fact sheet recommends a
modification in the limits for the three parameters. The previous permit writer had conferred with EPA
about the monthly average production value that should be used and it was decided that 24000 pounds
per day would be appropriate for calculation of daily maximum and monthly average limits. Pharr Yarns
is currently having compliance problems meeting the existing limits for sulfide, phenols, and total
chromium due to the stringency of those limits. This modification is to apply the appropriate limits as
calculated by effluent guidelines. The correct limits are listed below and all limits should be in lbs/day

CHANGES TO THE PERMIT
■ Revised limits for sulfide, phenols and total chromium will be given based on monthly
average production value of 24000 lbs/day projected for 2005. This monthly average
production number was used to calculate both the monthly average and daily maximum
limits. There should be no adjustment for percentage of process flow. The revised limits
will be higher than those given in 2005 permit.

Mike Montebello forwarded me the permit modification that you e-mailed him to review
because I handle the industrial discharges in SC. I noticed that your public comment
period ended on May 19. I just received this today and hoped my comments could still
be considered.
The permit that is attached does not include the limitations you referenced in your
letter. There seems to be a discussion of NET, nutrients and color, but not the
guideline parameters that were all d increased loadings. Could you send the
appropriate permit or permit pagqW to me for review?
Based on the Fact Sheet, I do not see any record of an antibackslding or
antidegradation review having been performed to show the need to relax the limits.
This may have been done, but justification was not provided in the fact sheet. If
this review was done, how was it decided that the additional load could be allowed?
In SC, our Water Quality Standards regulation requires we evaluate alternatives to
discharge (such as can they operate the system more efficiently to achieve existing
limits, can part or all of the wastewater be land applied or sent to a POTW, etc)
before increased loading will be allowed. We might also only allow a portion of the
increase rather than the entire amount allowed by guidelines. This allows for
additional protection of water quality.
Also, none of the attached documents discusses the water quality criteria for chromium
and sulfide in SC standards. I doubt with the dilution that it would be an issue, but
I wanted to make sure these were considered.

NC0004812 Pharr Yarns permit
Subject: NC0004812 Pharr Yarns permit
From: Jackie Nowell <[e-mail]>
Date: Fri, 02 Jun 2006 1.6:03:00 -0400
To: Michael Montebello <[e-mail]>, [e-mail]
Michael, per the request in the April 27 letter from Mihir Mehta regarding the subject
facility. The permit modification is for the revision of limits for sulfide, phenols,
and total chromium based on effluent guidelines for 40 CFR 410.70 Stock and Yarn
Finishing Subcategory.
Attached is the draft cover letter, draft permit and factsheet for Pharr Yarns. Pharr
Yarns discharges into the South Fork Catawba River with a 7Q10 of 125 cfs and an
average flow of 808 cfs. At 0.5 MGD, Pharr Yarns has an instream waste concentration
of 0.6 % . At the expansion flow of 1 MGD, the instream waste concentration is 1.2
%. The distance from the discharge point to the mouth of the South Fork Catawba River
where it enters the Catawba River is approximately 8.5 miles. North Carolina has an
action level standard for copper of 7 ug/1 and the allowable copper concentrations for
Pharr Yarns at the end of pipe would be 1136 ug/1 at 0.5 MGD and 572 ug/1 at 1.0 MGD.
If the SC standard for copper of 2.9 ug/1 is applied, the allowable concentration for
copper at 0.5 MGD is 471 ug/l, and at 1.0 MGD, the allowable concentration for copper
is 237 ug/l. There was one value for copper of 41 ug/l reported in the pollutant
analysis done in Dec. 2004. This data value is substantially less than the allowable
concentrations and would seem to indicate that copper is not a pollutant of concern
for Pharr Yarns. In addition, Pharr Yarns has consistently passed its whole effluent
toxicity test.
Regarding fecal coliform, the recommended and existing limitations in the Pharr Yarns
permit are 200/100ml (monthly average) and 400/100ml (daily maximum). Please contact
me if there are any further questions regarding the modification of the Pharr Yarns
permit.

RE: Notification of Intent to Renew NPDES Wastewater Permits for Pharr Yarns
(NC0004812), dated April 13, 2006.
Dear Ms. Bryant:
BOARD:
Carl L Beazell
Steven G. xisner
Paul C Aughtry, III
Coleman F. Bucki o se, MD
We are submitting comments regarding the above proposed NPDES permit modification,
which would continue the discharge of treated wastewater into the South Fork Catawba River.
Proposed discharge volume information was not provided in the above notice.
According to DHEC's latest approved 303(d) water quality assessment (2004), Lake
Wylie is impaired by copper levels above the Mill Creek arm at the end of SC Road 557 (CW-
197). Also, the Catawba River is impaired by copper levels at SC Road 5 above Bowater (CW-
041). South Carolina's standard for copper is 2.9 ug/l.
In addition, Lake Wylie (CW-027 located in the Crowders Creek arm at SC Highways 49
and 274) and the Catawba River (CW-014 at US Highway 21) are impaired by fecal colifonn
bacteria. South Carolina's standards for fecal coliform in the Catawba River are "not to exceed a
geometric mean of 200/100ml based on five day consecutive samples during any 30 day period;
nor shall more than 10% of the total samples examined during any 30 day period exceed
400/100m1 "
Please ensure that any permit modifications will not contribute to violations of South

Dear Mr. Chernikov:
1ti' FE3 27 ZOO
You may be aware that Pharr Yarns has been experiencing considerable difficulty
maintaining compliance with the current permit effluent limitations for sulfides. This
permit, issued March 1, 2005, contains sulfide limits of 0.8 lb/day, monthly average, and
2.3 lb/day, daily maximum.
Based on our experience, we have found that, if we have any detectable sulfide
concentrations in our effluent, the resulting calculated mass loadings (lb/day) will exceed
the mass effluent limits. Therefore, we have been reviewing this matter on several fronts
to get a better understanding of how these limits were derived.
In the course of this review, we have come across some interesting information that our
consultant, Mr. J. Thurman Horne, P.E. (Horizon Engineering & Consulting, Inc.)
discussed with you by phone on February 14, 2006. It is my understanding that, after
discussing this matter with Mr. Home, you agreed that it appears that the effluent limits
for sulfide, phenol and total chromium, may have been assigned incorrectly in the permit
due to a flaw in the derivation of the limits, and that this matter should be reviewed.
The key to this problem appears to be in the "Textile Effluent Limits Spreadsheet" that
was included with the Fact Sheet when the draft permit was first developed and sent to us
by letter dated November 24, 2004 (copy attached.) As you and Mr. Home have
discussed, the error appears near the bottom of the first page of the spreadsheet, where
calculations are made to allow for the contribution of BODS, TSS and COD attributable
to the domestic portion of the wastewater flow. The calculations correctly adjust the
calculated BODS, TSS and COD limits that were derived from the federal guideline (40
CFR 410.70 Subpart G) to account for the contribution of these constituents from the
domestic portion of the wastewater.
The problem is that, in the course of making these calculations, it appears that a mistake
was made wherein the limits calculated based on the federal guidelines for sulfides,
phenol and total chromium, were reduced to 27 % of the allowable limit. Whereas
compliance with this limit is determined by multiplying the concentration of the effluent
times the total flow (combined process and domestic wastewater) to determine the mass
effluent concentration, Pharr Yarns is currently being unfairly deprived of the full
federally allowable mass limits for sulfides, phenol and total chromium.

guidelines, should not have been reduced

Mike,

I have received -your letter with request to consider potential increase
in production. Accordingto your letter, it is expected that production
will increase 30% in 2005 compared to 2004. Production in 2004 was
19,499 lb/day (monthly average). Therefore, 2005 production level will
be 25,348 lb/day. EPA was not willing to accept thi� number, after
lengthy negotiation I was able to achieve their consepsus at the 24,000
lb/day and recalculated permit limits. Attached is the file with the new
limits. please let me know if these numbers are acceptable. I also had
to change methodology for calculating Daily Max. Limits due to EPA
objections.

Enclosed with this letter is a copy of the draft permit for your f"ry. Please review the draft very carefully
to ensure thorough understanding of the conditions and requirements it contains.
The draft pemlit contains the following significant changes from your current permit:
• The daily maxinnun total residual chlorine (TRC) limit has been added to the permit. See the
attached total residual chlorine policy memo for details. The facility is allowed 18 months from the
effective date of the permit to comply with the total residual chlorine limit. This time period is
Loved in order for the facility to budget and design/construct the dechlorination and /or
alternative disinfection systems.
• Limits for BOD, ODD, TSS and sulfide were changed due to the changes in production volume.
Please submit any comments to me no later than thirty days following your receipt of the draft. Comments
should be sent to the address listed at the bottom of this page. If no adverse comments are received from
the
005.ublic or from you, this permit will hkely be issued in early January, with an effective date of Febnrvy 1,
