Subject: Issuance of NPDES Permit NC0040797
Hickory -Henry Fork WWTP
Catawba County
Dear Mr. Kirby:
Division personnel have reviewed and approved your application for 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 May 9, 1994 (or as
subsequently amended.)
The following modifications have been added to the final permit:
• The Division may re -open this permit to require weekly average limits for ammonia. After
calculating allowable concentrations, the Division will perform an analysis of past ammonia data
to determine if there is a reasonable potential for this discharge to exceed these potential limits.
If there is, this permit will be re -opened. If there is not, the permit will not be re -opened, but
will contain weekly average limits for ammonia upon renewal.
• The requirement for instream monitoring at the downstream location (at N.C. Highway 10 at
the South Fork Catawba River) has been deleted. This monitoring location was eliminated
because the Division has an ambient monitoring station at that location. Hickory must continue
to monitor for temperature, dissolved oxygen and conductivity at State Road 1143.
The following modifications were made to the Hickory -Henry Fork WWTP draft permit and remain
a part of the final permit:
• A limit for total cadmium remains in the permit. A reasonable potential analysis of effluent data
predicts that the effluent has the potential to cause a violation of the water quality standard. A
daily maximum limit of 15 µg/1 and a weekly average of 6 µg/1 will be placed in the permit.
(Please note that the daily maximum limit has changed from 22 µg/l, which was a typographical
error that was inadvertently placed in the draft permit.)
• Limits for total nickel (258 µg/L weekly average and 261 µg/L daily maximum) have been added
to the permit. A reasonable potential analysis of effluent data predicts that the effluent has the
potential to cause a violation of the water quality standard.

•
• A daily maximum MBAS limit of 1467 µg/L has been added to the permit based on results of
the reasonable potential analysis.
• A total selenium limit of 14.7 µg/L (daily maximum) has been added to the permit based on
results of the reasonable potential analysis.
• A fluoride limit of 5283 µg/L (daily maximum) has been added to the permit based on results of
the reasonable potential analysis.
• The total chromium limit has been deleted. A reasonable potential analysis of effluent data
predicted that the effluent concentration does not have potential to cause a violation of the
water quality standard. Chromium monitoring will remain in the Long Term Monitoring Plan
under Hickory's pretreatment program.
• The total lead limit has been deleted. A reasonable potential analysis of effluent data predicted
that the effluent concentration does not have potential to cause a violation of the water quality
standard. Lead monitoring will remain in the Long Term Monitoring Plan under Hickory's
pretreatment program.
• The total cyanide limit has been deleted. A reasonable potential analysis of effluent data
predicted that the effluent concentration does not have potential to cause a violation of the
water quality standard. Effluent monitoring for cyanide will continue at 2/month.
• The total mercury limit has been deleted. A reasonable potential analysis of effluent data
predicted that the effluent concentration does not have potential to cause a violation of the
water quality standard. Mercury monitoring will remain in the Long Term Monitoring Plan
under Hickory's pretreatment program.
• The bis (2-ethylhexyl) phthalate limit has been deleted based on current information that the
presence of this substance may be laboratory contamination.
• The addition of color monitoring and reduction requirements based on results of AWARE
Environmental study, the DWQ Color Permitting Policy, and findings and recommendation of
the Color Discharger Public Hearing held August 28, 2001.
The City of Hickory has requested the North Carolina water quality standard on color be furnished
to them. The standard for color is a narrative standard from the North Carolina regulation 15A NCAC 2B
.0208(f): "Oils, deleterious substances; colored or other wastes: only such amounts as shall not render the
waters injurious to public health, secondary recreation or to aquatic life and wildlife or adversely affect the
palatability of fish, aesthetic quality or impair the waters for any designated uses; for the purpose of
implementing this Rule, oils, deleterious substances, colored or other wastes shall include but not be limited
substances that cause a film or sheen upon or discoloration of the surface of the water or adjoining
shorelines....".
The effluent from Hickory's WWTP affected the aesthetic quality and discolored the surface of the
water in the Henry Fork River. Therefore, the following special condition has been added to the permit
This facility has been classified as a Tier 3 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.

Permit NC0040797
Page 3
The permittee will prepare a Pollution Prevention/Best Management Practices (BMPs) report. This
report will address the potential for the facility to reduce effluent color by incorporating pollution
prevention measures and/or BMPs prior to treatment. This report could include an evaluation of
the dyeing process, looking at the potential for dye substitution, improving dyeing efficiencies, etc.
The report could also investigate whether any BMPs could be implemented that would reduce the
amount of color discharged to the treatment plant. The permittee could do this work
independently, or request voluntary assistance from the North Carolina Division of Pollution
Prevention and Environmental Assistance. The permittee will also prepare a Color Reduction
Study, which will involve an end -of -pipe treatment evaluation that develops cost estimates for
reducing effluent color by 75% and 90%. Both reports will be submitted within 24 months of the
permit effective date.
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.
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 a demand is made, this permit
shall be final and binding.
Please take notice that this permit is not transferable. 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, Coastal Area Management Act, or any other Federal or Local governmental permits may
be required.
If you have any questions or need additional information, please contact Ms. Jacquelyn Nowell at

A. (1). EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
(continued)
Notes:
3 The Division may re -open this permit to require weekly average limits for ammonia. After calculating allowable
concentrations, the Division will perform an analysis of past ammonia data to determine if there is a reasonable
potential for this discharge to exceed these potential limits. If there is, this permit will be re -opened . If there is
not, the permit will not be re -opened, but will contain weekly average limits for ammonia upon renewal.
4 The daily average dissolved oxygen effluent concentrations shall not be less than 5.0 mg/L.
5 The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units.
6 Limitation and monitoring requirement applies only if chlorine is added during treatment.
7 Chronic Toxicity (Ceriodaphnia) P/F @ 34%; February, May, August and November. See A. (2.).
8 The quantitation limit for cyanide shall be 10 pg/L (10 ppb). Levels reported as "<10 gg/L" shall be considered
zero for compliance purposes.
9 Color samples will be analyzed for ADMI color at natural pH. Samples will be analyzed by a state certified
laboratory. See A. (3).
There shall be no discharge of floating solids or visible foam in other than trace amounts.
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 34 %.
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: NC DENR DWQ / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days
after the end of the reporting period for which the report is made.
(continued on ncxt page)

Permit NC0040797
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
(continued)
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 Branch at the address cited
above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include
alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid
test and will require immediate follow-up testing to be completed no later than the last day of the month following the
month of the initial monitoring.
A. (3.) COLOR PERMITTING REQUIREMENTS FOR TIER 3 FACILITY
This facility has been classified as a Tier 3 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.
The permittee will prepare a Pollution Prevention/Best Management Practices (BMPs) report. This report will address
the potential for the facility to reduce effluent color by incorporating pollution prevention measures and/or BMPs
prior to treatment. This report could include an evaluation of the dyeing process, looking at the potential for dye
substitution, improving dyeing efficiencies, etc. The report could also investigate whether any BMPs could be
implemented that would reduce the amount of color discharged to the treatment plant. The permittee could do this
work independently, or request voluntary assistance from the North Carolina Division of Pollution Prevention and
Environmental Assistance. The permittee will also prepare a Color Reduction Study, which will involve an end -of -pipe
treatment evaluation that develops cost estimates for reducing effluent color by 75% and 90%. Both reports will be
submitted within 24 months of the permit effective date.
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.

We have received the Henry Fork WWTP Draft Permit from your office. The Public Services
Manager, Senior Plants Supervisor, Plant Operator in Responsible Charge, Pretreatment Coordinator
and Regional Lab Supervisor have all reviewed the contents of the Draft Permit and are acceptable
with the proposed effluent limitations and monitoring requirements.
Color monitoring and reduction requirements are an addition to this permit and we are requesting
some clarification. Mr. James Kirby, Senior Plants Supervisor, recently spoke with you by telephone
and we still have the following concerns:
• What are the Water Quality Standards related to Color?
• What period of time and data requirements is necessary to request a permit modification in
regard to color?
• Should that section read effluent instead of influent color reduction in order for us to
realistically calculate plant reduction by 75% and 90%?
Also, we are respectfully requesting the elimination of the downstream sampling location at NC
Highway 10. On our present permit and on the draft permit we are required to have two downstream
sampling locations. We feel that there has been sufficient data recorded to be able to exclude the
pig sampling point at this time. Another factor is that the traffic volume on Highway 10 has increased
v„4 , ,s dramatically over the past several years. The bridge where the samples are taken is very hazardous
,.-• in itself. Please consider our petition to exclude the downstream sample location at NC Hwy. 10 at
the South Fork Catawba River.

Hello Marshall, in response to your comments.
Item #1, there needs to be a correction here. The previous limits for
cadmium were daily maximum limits of 7.8 ug/1 at 6.0 MGD and 6.0 ug/1 upon
expansion to 9.0 MGD. These limits were based on the NC water quality
standard and dilution under summer 7Q10 flow conditions. These limits were
based on chronic criteria, but were placed in the permit as a daily maximum
limit to protect for both acute and chronic effects. A weekly average
limit had been requested by some dischargers to be more reflective of the
chronic basis.
In April 28 1999, DWQ developed new guidance to modify toxicant limits by
including new daily maximum limits equal to one half of the Final Acute
Value established by EPA and a weekly average limit for protection of
chronic effects. The previously assigned daily maximum limit would become
the weekly average limit. Since the Hickory Henry Fork WWTP has expanded
to 9.0 MGD, at this permit renewal, the new guidance for these limits went
into effect. A weekly average limit of 6.0 ug/1 was assigned for
protection of chronic and a daily maximum limit of-22 ug/1 was assigned for
protection of acute effects. The 22 ug/1 limit should be corrected to 15
ug/1, the 1/2 FAV value for cadmium in non -trout waters. (22 ug/1 is the
1/2 FAV for cyanide).
Item #2 -NH3 - in the resolution stages
.Item #3 - Will add "total" to metals.
Please advise if any additional questions.

DEC-14-2001 11:28 FROM DEM WATER QUALITY SECTION TO 88282941740 P.02/02
AMENDMENT TO NPDES PERMIT APPLICATION
Background
In mid-2001 the US. Environmental Protection Agency, which oversees North Carolina's
NPDES permit program, determined that the state's application form for major municipal
dischargers is inadequate. The EPA indicated that the form does not require a summary of the
applicant's wastewater characteristics, as EPA's standard form does, and does not
provide the necessary public record for permit issuance. Since July 2001, EPA has objected to
the issuance of approximately forty permit renewals until the permittees provide complete
applications.
In recent discussions with the Division of Water Quality, the EPA recently agreed that the
Division may provide the monitoring information on each permnittee's behalf rather than require
the facilities to complete new applications. The permittees have already submitted discharge
monitoring reports (DMRs) under the terms of their NPDES permits, and the Division
can easily produce summaries for each facilty. However, the Division does not have the legal
authority to amend a facility's application; each pennittee must give its consent in order for the
Division to submit this information on its behalf. North Carolina will provide a summary of
discharge monitoring reports as additional documentation to ensure the record is complete.
The statement below is designed to give the Division the authority to submit this data on behalf
of the permittee for this one instance. Other than signing the statement below, no further
action will be required on the part of the permit holder. Furthermore, this will not
change the substance of the draft permit already issued by the Division.
PLEASE SIGN AND RETURN THE FOLLOWING STATEMENT AS SOON AS
POSSIBLE. THIS STATEMENT WILL CONSTITUTE AN OFFICIAL PERMIT
AMENDMENT. In order to expedite the renewal of your permit, please fax the signed
form to (919)-733-0719 and send the original to:

Permit No. NC0040797
Hickory -Henry Fork WWTP
Catawba County
Dear Mr. Kirby:
The Division of Water Quality (DWQ) has drafted a NPDES permit for the above
referenced facility. The Director of the Division, pursuant to NCGS 143-215.1(c)(3) and
Regulation 15 NCAC 2H, Section .0100 has determined that it is in the public interest that a
meeting be held to receive all pertinent public comment on whether to issue, modify or deny the
permit. The primary issue of the public meeting is the discharge of colored effluent from the
Hickory -Henry Fork WWTP. This meeting will be held Tuesday, August 28, 2001 at 7:00 p.m. at
the Citizens Resource Center, 1303 Cherryville Highway in Dallas, N.C. We will be calling within
the next few weeks to schedule a facility site visit prior to the public meeting.
The following modifications have been made to the Hickory -Henry Fork WWTP draft
permit and are as follows:
• A limit for cadmium remains based on reasonable potential analysis that predicts that the
effluent has the potential to cause a violation of the water quality standard. A daily maximum
limit of 22 ug/1 and a weekly average of 6 ug/1 will be placed in the permit.
• A nickel limit of 258 ug/1(weekly average) and 261 ug/1 (daily maximum) will be added to the
permit based on results of the reasonable potential analysis that predicts that the effluent has
the potential to cause a violation of the water quality standard.
• A MBAS limit of 1467 ug/1 (daily maximum) will be added to the permit based on results of
the reasonable potential analysis.
• A selenium limit of 14.7 ug/1 (daily maximum) will be added to the pexmit based on results of
the reasonable potential analysis.
• A fluoride limit of 5283 ug/1 (daily maximum) will be added to the permit based on results of
the reasonable potential analysis.
• The chromium limit of 147 ug/1 will be dropped based on results of the reasonable potential
analysis that predicted that the effluent concentration does not have potential to cause a
violation of the water quality standard. Chromium monitoring will be continued in the Long
Term Monitoring Plan under Hickory's pretreatment program

Draft Permit
• The lead limit of 73 ug/1 will be dropped based on results of the reasonable potential analysis
that predicted that the effluent concentration does not have potential to cause a violation of the
water quality standard. Lead monitoring will be continued in the Long Term Monitoring Plan
under Hickory's pretreatment program.
• The cyanide limit of 15 ug/1 will be dropped based on results of the reasonable potential
analysis that predicted that the effluent concentration does not have potential to cause a
violation of the water quality standard. Recommend that continuation of effluent monitoring
for cyanide will be 2/month.
• The mercury limit of 0.04 ug/1 will be dropped based on results of the reasonable potential
analysis that predicted that the effluent concentration does not have potential to cause a
violation of the water quality standard. Mercury monitoring will be continued in the Long
Term Monitoring Plan under Hickory's pretreatment program
• The Bis (2-ethylhexyl) phthalate limit of 77 ug/l will be dropped based on current DWQ
information that the presence of this substance may be laboratory contamination.
• The addition of color monitoring and reduction requirements based on results of AWARE
Environmental study.
This facility has been classified as a Tier 3 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.
The permittee will prepare a Pollution Prevention/Best Management Practices (BMPs) report.
This report will address the potential for the facility to reduce effluent color by incorporating
pollution prevention measures and/or BMPs prior to treatment. This report could include an
evaluation of the dyeing process, looking at the potential for dye substitution, improving dyeing
efficiencies, etc. The report could also investigate whether any BMPs could be implemented
that would reduce the amount of color discharged to the treatment plant. The permittee could
do this work independently, or request voluntary assistance from the North Carolina Division
of Pollution Prevention and Environmental Assistance. The permittee will also prepare a Color
Reduction Study, which will involve an end -of -pipe treatment evaluation that develops cost
estimates for reducing influent color by 75% and 90%. Both reports will be submitted within
24 months of the permit effective date.
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.

PART IV - EVALUATION AND RECOMMENDATIONS
The City of Hickory requests reissuance of the subject permit. Additional WWT facilities
approved in the ATC dated March 2, 1994 have been constructed, which increased the WWTP's
design capacity from 6.0 MGD to 9.0 MGD. During expansion process, the City converted the
WWTP to an activated sludge process and eliminated the rotating biological contactors.
Color continues to dominate the influent to this facility. WWTP staff have, however, been
able to effectively reduced effluent color through adjustments in the biological treatment process.
These operational adjustments have effectively reduced effluent color to a level that only slightly
increases in -stream color at the point of discharge, and is almost non-existent a few hundred yards
downstream.
Pending a review and approval of the WLA, it is recommended that the permit be renewed as
requested.

Before you start assigning Catawba files to folks, there are some facilities that may require additional
background info noted below. I'll put a copy of this email into those files, to tip off permit writer about
issues to address.
• Color Dischargers- Currently 8 facilities in Color Alliance, plus Newton which did not join. There
will be some language to add in cover letter and possibly permit for these facilities regarding color
study. Charles- I'll give you a hardcopy list of these facilities, and I'm o.k. if you assign them to me.
• Valdese WWTP- At the ESB meeting this week on Lakes James/ Rhodhiss/Hickory, there was
concern about the increasing TP loading from this facility. Although the load does not appear to
impact Lake Rhodhiss, we don't know how much will be exported downstream to Lake Hickory,
since Rhodhiss doesn't appear to be a TP sink. No need for limits, but Coleen thought we should put
something in permit cover letter asking them to evaluate why TP load is increasing; indicate that
there is concern about downstream lake; and possibly have them do TP optimization study. Michele
W. is looking into how much TP is exported from Lake Rhodhiss to Lake Hickory. Forest W. will
have Jim Reid discuss TP situation with facility.

PROPOSED SANIPLING PLAN FOR
SOUTH FORK CATAWBA RIVER COLOR STUDY
Background
The South Fork Catawba River Water Quality Alliance Inc. (Alliance) has initiated a program
to evaluate the discharge of color and the effect of the color discharges on the South Fork
Catawba River (South Fork). The objectives of this program are:
1. To provide a high quality database on South Fork color; and
2. To determine if there is a color problem in the South Fork, and if so, if it is related to
any of the Alliance discharges.
There are eight (8) dischargers involved in this color study. They are:

This study will provide a long-term data baseline from which to evaluate the color in the river.
A detailed sampling protocol and quality control program will be implemented in conjunction
with this program to ensure representative data. The color monitoring procedures for this
program will utilize the procedures recommended by the North Carolina Department of
Environment and Natural Resources (NCDENR) and laboratories certified by the State of
North Carolina to conduct these analyses. This report presents the proposed plan for the
conduct of this study.
Monitoring
To develop the required data a detailed monitoring plan is proposed. Monitoring will include
effluent and river samples for ADMI color, pH and temperature. The river samples will
include upstream and downstream samples of all Alliance discharges, samples at NCDENR
monitoring locations, and samples from selected river locations. All river samples will be
monitored for turbidity. Pictures will be taken of the river at the point of the discharge in

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
Because of the number of textile mills that discharge into the Henry Fork WWTP, there
has been a complaint about its colored discharge into the Henry Fork River. A public
hearing on the renewal of the permit has been requested by the Catawba River
Foundation and will be held inflate August 2001.
ate,
The City of Hickory is requesting renewal of the Henry Fork WWTP. The WWTP discharges into
Henry Fork River, a class C stream, in CTB35 subbasin. The use support rating for the
segment of Henry Fork where Hickory discharges is rated Fully supporting from SR1124 to SR
1143. There are some problem parameters of fecal coliform and turbidity with the major
sources being nonpoint. A segment of Henry Fork below the Hickory discharge point is listed
on North Carolina's 2000 303(d) list. From SR1143 to the South Fork Catawba River, an
eight -mile stretch of Henry Fork is rated fully supporting with the problem parameters of Y4-
turbidity. *This is an updated use support rating and the segment is no longer impaired for
fecal coliform based on new physical/chemical data. 1.; ,..•- wfr-VI

INSTREAM MONITORING:
Upstream Site: Henry River
Downstream Site #1: Bridge on State Road 1143
Downstream Site #2: Bridge on Highway 10 1' `-
Facility currently monitors instream for temperature, DO, fecal coliform and conductivity.
Reviewed instream data for months of April through October for years 1998 through 2000.
Most instream data showed -the protection - of DO standard of 5 mg/1 below the discharger, and
exceedances of fecal coliform standard of 200/ 100m1. In June and July 1999, there were
instances where the DO was substandard with values as low as 3.7 mg/1 being reported. Ct'''
However, the monthly averages for DO in both June and July 1999 were above the 5-mg/1
standard.
Recommendation: continuation of all existing instream parameters.
Color issues must be addressed in the South Fork Catawba River. Instream monitoring l t'(D 13.
for color may be required per results of color study.
PROPOSED CHANGES:
The following modifications have been made to the permit:

Aware Environmental study.
This facility has been classified as a Tier 3 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.
The permittee will prepare a Pollution Prevention/Best Management Practices (BMPs) report.
This report will address the potential for the facility to reduce effluent color by incorporating
pollution prevention measures and/or BMPs prior to treatment. This report could include an
evaluation of the dyeing process, looking at the potential for dye substitution, improving
dyeing efficiencies, etc. The report could also investigate whether any BMPs could be
implemented that would reduce the amount of color discharged to the treatment plant. The
permittee could do this work independently, or request voluntary assistance from. the North
Carolina Division of Pollution Prevention and Environmental Assistance. The permittee will
also prepare a Color Reduction Study, which will involve an end -of -pipe treatment evaluation
that develops cost estimates for reducing influent color by 75% and 90%. Both reports will
be submitted within 24 months of the permit effective date.
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.
ALL OTHER EXISTING PERMIT LIMITS AND MONITORING REQUIREMENTS WILL REMAIN
THE SAME.

MEMORANDUM
To: Tommy Stevens
Through: Coleen Sullins
Bill Reid
Dave Goodrich
From: Tom Belnick
Subject: NPDES Color Permitting Policy
Catawba River Basin Color Dischargers
This NPDES Color Permitting Policy addresses eight color dischargers in the South Fork
Catawba River watershed (subbasins 030835 and 030836) . The policy provides for a tiered
permitting approach, ranging from color monitoring for facilities showing no color plume, up to
color reduction limits for facilities exhibiting major color plumes and downstream aesthetic
impacts.
Background. The South Fork Catawba River watershed was identified in previous basin plans
as having a high concentration of textile dischargers, along with public concerns and
complaints regarding color from such discharges. In August 1999 the Division met with
selected color dischargers in the watershed to address the color issue. As a result of this
meeting, eight color dischargers (Pharr Yarns, Delta Mills, Yorkshire, Cramerton, Lincolnton,
Gastonia -Long Creek, Hickory, and Cherryville) elected to form the South Fork Catawba River
Water Quality Alliance and undertake a comprehensive color monitoring study to identify
current color problem areas in the watershed. The color monitoring was conducted twice per
month from April through November 2000, and included color monitoring of effluent,
upstream and downstream stations, as well as reference sites. The study included analytical
color measurements (ADMI units), visual observations, and photographs. The study period
included an extremely dry summer, and should represent worst case conditions. In addition,
the study represents the most current assessment of color conditions in the watershed, given
the changing nature of textile facilities across the state. The Alliance submitted individual
reports to the Division for each sampling event, as well as a Final Color Study Report (AWARE
Environmental, Inc., March 2001). One color discharger in the watershed (City of Newton)
elected to evaluate color independently from the Alliance members, using similar monitoring
protocols.
Color Regulation. According to state regulation [15A NCAC 02B.0211(3)(f)], colored effluent is
allowed in "only such amounts as shall not render the waters injurious to public health,
secondary recreation or to aquatic life and wildlife or adversely affect the palatability of fish,
aesthetic quality or impair the waters for any designated uses." To date, there are no data to
show that the colored effluent is posing a human health concern, or that color is a source of
impact on the aquatic biota. Therefore, aesthetic concerns are the primary issue associated
with the narrative color standard.
NPDES Color Permitting Policy
Page 1 of 5

Data Evaluation. The evaluation of color as an aesthetic impact is difficult since it is a
subjective determination. In addition, a host of factors, such as hue, instream turbidity,
suspended matter, dilution, light conditions, and downstream access all play a part in
determining when a color impact might be perceived by the public.
The ADMI method used to measure color quantitatively in the study takes into account the
entire visible spectrum, and was originally developed to be related to visual perceptibility.
During data review, it was realized that ADMI color measurements do not always predict the
potential for a color impact. For example, a color plume with downstream aesthetic impact
was observed at Cherryville on several sampling events, although the effluent ADMI color was
low (summer average = 63 ADMI) and similar to upstream values. The plume was likely due to
the particular hue of the effluent and the low instream dilution, rather than an absolute ADMI
value. In this situation, consideration of a numerical instream ADMI color standard would be
ineffective. However, requiring some percentage reduction in effluent color would help to
minimize the size of the color plume. Conversely, some facilities with greater colored effluent
(e.g., Pharr Yarns and Yorkshire with summer averages of 844 and 3449 ADMI units,
respectively) did not produce major instream color plumes, most likely due to the effluent hue
as well as the large dilution available. Therefore, in order to evaluate the data, it was realized
that no single criterion, but rather a combination of ADMI measurements, photographs, and
plume descriptions were needed to fully assess the instream color conditions.
Specific data utilized from the Final Color Study Report submitted by the Alliance included: 1)
frequency of plumes observed at the outfall (see Appendix A, Table 5-2); 2) frequency of
visual color change at the downstream station (see Appendix A, Table 5-1); and 3) statistical
color difference between upstream and downstream stations during summer (see Appendix A,
Table 4-2) . The study reported that Pharr Yarns was the only facility that did not produce a
color plume at the outfall at any time during the study, while for the remaining facilities, color
plumes were reported observed at the outfalls from 60% to 100% of the time. The study also
reported that visual changes in downstream color were observed at the following frequencies:
Hickory (20%), Cherryville (60%), Delta Mills (87%), and 0% for the remaining facilities.
Finally, the study reported the largest measured summer increases in ADMI color at the
downstream station at the following facilities: Gastonia -Long Creek (23% increase), Hickory
(31% increase), and Delta Mills (58% increase). Downstream stations were located between 0.5
to 2.5 miles below the outfalls, generally at accessible bridge locations. Thus, comparison of
various downstream impacts must be made with this fact in mind.
The data from the report was supplemented with visual observations made by Division staff
during an August 22, 2000 site visit to all outfalls and downstream stations. The consensus
from the site visit was that significant color plumes were evident at outfalls from Delta Mills,
Cherryville, Hickory, and Gastonia -Long Creek. These were not single incidents, as report
photographs attest to their recurrence during the study. Color pictures of these plumes taken
from various sampling dates are included in Appendix A. Color plumes at the other facility
outfalls were either nonexistent or much less noticeable.
Tiered Classification. The NPDES Color Permitting Policy establishes four tiers of action
based on varying aesthetic color impacts to the receiving waters. The tier groupings were
based on the data reported in the Final Color Study Report, as well as field observations made
by Division staff. The Tier 1 facility showed no visible color plume during the color study. Tier
2 facilities showed minor color plumes at the outfall and limited downstream color impact.
Tier 3 facilities showed significant color plumes at the outfall and at times greater downstream
NPDES Color Permitting Policy
Page 2 of 5

color impact. Finally, the Tier 4 facility showed significant plumes at the outfall and
significant downstream color impacts. The data are summarized in Table 1.
It should be noted that Gastonia -Long Creek was originally placed in Tier 3 based on color
study results. However, after the color study was completed, their major color discharger
(Fleishman's Yeast) was removed, resulting in a Tier 2 re -ranking. Also, Cherryville is
currently ranked as Tier 3 based on color study results, but is scheduled to lose their lone
textile discharger in July 2001. After this color source is removed, Cherryville can request a
re -ranking with subsequent reduction in permitting requirements.

Color Permitting Policy. All eight Catawba Basin facilities are currently up for permit
renewal, and the basin renewal schedule will extend the permits into 2005. Based on the tier
groupings, progressive permitting actions have been developed for these facilities, ranging from
color monitoring (Tier 1), pollution prevention studies (Tier 2), engineering cost studies for
end -of -pipe treatment (Tier 3), and finally color reduction limits (Tier 4). Color monitoring will
remain a baseline condition for all facilities, as long as color remains a component of the
discharge. Instream stations will be monitored for color monthly during summer, when low
flows represent the most likely period for instream aesthetic impacts.... Effluent will be
monitored for color monthly on a year-round basis, to track the consistency of the color input.
NPDES Color Permitting Policy
Page 3 of 5

All color dischargers will also receive a Color Reopener Special Condition, which will allow
permits to be reopened and additional restrictions imposed if color problems persist. The color
limits for the Tier 4 facility will be expressed as a 90% color reduction requirement between
influent and effluent. As discussed previously, a color limit expressed as a percentage
reduction in effluent color should significantly reduce the size of the instream color plume and
aesthetic impact, while avoiding the complications of any single numerical ADMI color limit.
The color permitting requirements are summarized in Table 2, and specific permitting
language is included in Appendix B.

Additional Facilities. As previously mentioned, the City of Newton (NC0036196) was
originally identified as a color discharger to the South Fork Catawba River watershed, along
with the Alliance members. However, the City of Newton elected to evaluate color conditions
independently from the Alliance. The Division conducted a site visit to the Newton WWTP
prior to permit renewal, and observed a minor color plume at the outfall. In the permit
renewal issued to Newton on March 2, 2001, the permit included monthly summer color
monitoring, as well as a Color Reopener Special Condition. Based on the current tiered
classification, Newton would rank as a Tier 2 facility. Therefore, it is recommended that the
NPDES Color Permitting Policy
Page 4 of 5

Newton permit be reopened, and color requirements consistent with Tier 2 facilities be
incorporated. This would include the additional requirement for a P2/BMP report.
One facility with colored effluent and a significant color plume which was not evaluated in the
color study is the City of Gastonia- Crowders Creek WWTP (NC0074268) . This discharge is
also located in the Catawba River Basin (subbasin 030837) . Several recent color complaints
have been received for this facility, and Division staff observed a significant color plume during
a recent site visit. This facility is also up for permit renewal. It is recommended that Tier 3
color requirements be placed in the permit renewal.
Conclusion. It is the overall goal of this permitting policy to reduce the magnitude of color
plumes to a level where aesthetic color complaints are infrequent. The Point Source Branch
requests your comments and concurrence with our permitting policy. Please feel free to call
me at extension 543 if you have any questions or comments.

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
Because of the number of textile mills that discharge into the Henry Fork WWTP, there
has been a complaint about its colored discharge into the Henry Fork River. A public
hearing on the renewal of the permit has been requested by the Catawba River
Foundation and will be held August 28, 2001.
The City of Hickory is requesting renewal of the Henry Fork WWTP. The WWTP discharges into
Henry Fork River, a class C stream, in CTB35 subbasin. The use support rating for the
segment of Henry Fork where Hickory discharges is rated Fully supporting from SR1124 to SR
1143. There are some problem parameters of fecal coliform and turbidity with the major
sources being nonpoint. A segment of Henry Fork below the Hickory discharge point is listed
on North Carolina's 2000 303(d) list. From SR1143 to the South Fork Catawba River, an
eight -mile stretch of Henry Fork is rated fully supporting with problem parameter of turbidity.
*This is an updated use support rating and the segment is no longer impaired for fecal coliform
based on new physical/chemical data.
The facility operates a 9.0 MGD plant consisting of a mechanical bar screen, continuous flow
measurement, an influent pump station, grit removal, flow equalization basin, 2 primary
clarifiers, two aeration basins, two secondary clarifiers, chlorine gas disinfection with contact
chamber, dechlorination, cascade aeration, defoamer additon, chemical oxidation of sludge,
sludge drying beds, aerated sludge holding basins, alum and polymer feed systems, and
standby power generator.
The plant services 14,650 residents in the City of Hickory, and also serves the Town of
Brookford with a population of 550 and the Town of Longview with a population of 3600.
Nearly, 19,000 people are served.

*Per the MRO staff report - Color dominates the effluent of the plant. WWTP staff have
been able to effectively reduce effluent color through adjustmenst in the biological
treatment process. These adjustment s have reduced effluent color to a level that only
slightly increases instream color at the point of discharge, and is almost nonexistent a
few hundred yards downstream.

. REASONABLE POTENTIAL ANALYSIS:
Performed analysis on Discharge Monitoring Report data from 1999 through August 2000 on
the parameters, Cd, Cr, Cu, Pb, Ni, Zn, As, Se, Ag, Hg, Cn, and Fluoride. Long term
monitoring data from the pretreatment program is included on the discharge monitoring
reports.
Existing limits and monitoring are as follows:
Cadmium = 6.0 ug/1 (daily max.)
Chromium = 147 ug/1 (daily max.)
Lead = 73 mg/1 (daily max.)
Cyanide = 15.0 ug/1 (daily max.)
Mercury = 0.04 ug/1 (daily max.)
Bis (2-ethylhexyl) phthalate = 77 ug/1 (daily max.)
2/month monitoring for copper, MBAS, chloride, silver and zinc.
Results of reasonable potential analysis:
• A limit for cadmium remains based on reasonable potential analysis that predicts that the
effluent has the potential to cause a violation of the water quality standard. A daily
maximum limit of 22 ug/1 (based on EPA's 1/2 FAV) and a weekly average of 6 ug/1 will be
placed in the permit.
• A nickel limit of 258 ug/1 (weekly average) and 261 ug/1 (daily maximum, based on 1/2 FAV)
will be added to the permit based on results of the reasonable potential analysis that
predicts that the effluent has the potential to cause a violation of the water quality
standard.
• A MBAS limit of 1467 ug/1 (daily maximum) will be added to the permit based on results of
the reasonable potential analysis that predicts that the effluent has the potential to cause a
violation of the water quality standard.
• A selenium limit of 14.7 ug/1 (daily maximum) will be added to the permit based on results
of the reasonable potential analysis that predicts that effluent has the potential to cause a
violation of the water quality standard.
• A fluoride limit of 5283 ug/1 (daily maximum) will be added to the permit based on results
of the reasonable potential analysis that predicts that the effluent has the potential to cause
a violation of the water quality standard.
• Chloride monitoring will be continued in the permit based on results of the reasonable
potential analysis that predicts that the effluent has the potential to cause an exceedance of
the N.C. action level. Effluent monitoring for chloride will be 2/month.
• Silver monitoring will be continued in the permit based on results of the reasonable
potential analysis that predicts that the effluent has the potential to cause an exceedance of
the N.C. action level. Effluent monitoring for silver will be 2/month
• The chromium limit of 147 ug/1 will be dropped based on results of the reasonable potential
analysis that predicted that the effluent does not have the potential to cause a violation of
the water quality standard. Chromium monitoring will be continued monthly in the Long
Term Monitoring Plan under Hickory's pretreatment program.
• The lead limit of 73 ug/1 will be dropped based on results of the reasonable potential
analysis that predicted that the effluent does not have the potential to cause a violation of
the water quality standard. Lead monitoring will be continued monthly in the Long Term
Monitoring Plan under Hickory's pretreatment program.
• The cyanide limit of 15 ug/1 will be dropped based on results of the reasonable potential
analysis that predicted that the effluent does not have the potential to cause a violation of
the water quality standard. Effluent monitoring for cyanide will be 2/month.
• The mercury limit of 0.04 ug/1 will be dropped based on results of the reasonable potential
analysis that predicted that the effluent does not have the potential to cause a violation of
the water quality standard. Analysis was done on 100 data points and all were below
detection. Mercury monitoring will be continued quarterly in the Long Term Monitoring
Plan under Hickory's pretreatment program.
• The Bis (2-ethylhexyl) phthalate limit of 77 ug/1 will be dropped based on current DWQ and
EPA information that the presence of this constituent may be based laboratory
contamination. Bis 2 is a plasticizer used in numerous plastic products, ie gloves, plastic
buckets, bottles. NC lab personnel state that this substance would have to be present in
very high levels (i.e. 100+ ug/1) to be considered problematic. Bis 2 values were below
detection in 8 Of 11 values reported.
• Arsenic was evaluated based on long term monitoring data for 1999 and 2000. Results of
the reasonable potential analysis that predicted that the effluent does not have the potential

to cause a violation of the water quality standard. Analysis was done on 23 data points and
all were below detection. Arsenic monitoring will be continued quarterly in the Long Term
Monitoring Plan under Hickory's pretreatment program.
COMPLIANCE SUMMARY:
Through April 2001, Avg. Qw = 3.3 MGD (approximately 55% of capacity), BOD5=13.5 mg/1,
NH3=7.3 mg/1, TSS=18.5 mg/1, TN=9.5 mg/ and TP=2.08 mg/1.
In 2000, Avg. Qw = 2.7 MGD (approximately 45% of capacity), BOD5=15.0 mg/1, NH3=11.9
mg/1, TSS=20.4 mg/1, TN=10.6 mg/ and TP=2.62 mg/1. One TSS violation in January and
one pH violation in December
In 1999, Avg. Qw = 3.05 MGD (approximately 51% of capacity), BOD5=13.0 mg/1, NH3=6.35
mg/1, TSS=16.6 mg/1, TN=7.7 mg/ and TP=1.51 mg/1.
In 1998, Avg. Qw = 3.27 MGD (approximately 55% of capacity), BOD5=12.5 mg/1, NH3=3.52
mg/1, TSS=14.7 mg/1, TN=9.8 mg/ and TP=2.32 mg/1. One flow violation in February and

mg/1, TSS=17.3 mg/1, TN=12.6 mg/ and TP=2.4 mg/1.
INSTREAM MONITORING:
Upstream Site: Henry River
Downstream Site #1: Bridge on State Road 1143
Downstream Site #2: Bridge on Highway 10
Facility currently monitors instream for temperature, Dissolved Oxygen(DO), fecal coliform and
conductivity. Reviewed instream data for months of April through October for years 1998
through 2000. Most instream data was greater than the DO standard of 5.0 mg/1 below the
discharge. There few exceedances of fecal coliform standard of 200/ 100m1, either upstream or
downstream of the Hickory discharge. Since October 1999, there has been only one instance
where the average downstream fecal coliform was greater than the standard of 200m1.
Recommendation: continuation of all existing instream parameters.
Color issues must be addressed in the South Fork Catawba River. Instream monitoring for
color may be required per results of color study.
PROPOSED CHANGES:
The following modifications have been made to the permit:
• A limit for cadmium remains based on reasonable potential analysis. A daily maximum
limit of 22 ug/1 (based on EPA's i/a FAV) and a weekly average of 6 ug/1 will be placed in the
permit.
• A nickel limit of 258 ug/1 (weekly average) and 261 ug/1 (daily maximum, based on '/2 FAV)
will be added to the permit based on results of the reasonable potential analysis.
• A MBAS limit of 1467 ug/1 (daily maximum) will be added to the permit based on results of
the reasonable potential analysis.
• A selenium limit of 14.7 ug/1 (daily maximum) will be added to the permit based on results
of the reasonable potential analysis.
• A fluoride limit of 5283 ug/1 (daily maximum) will be added to the permit based on results
of the reasonable potential analysis.
• The chromium limit of 147 ug/1 will be dropped based on results of the reasonable potential
analysis. Chromium monitoring will be continued in the Long Term Monitoring Plan under
Hickory's pretreatment program.
• The lead limit of 73 ug/1 will be dropped based on results of the reasonable potential
analysis. Lead monitoring will be continued in the Long Term Monitoring Plan under
Hickory's pretreatment program.
• The cyanide limit of 15 ug/1 will be dropped based on results of the reasonable potential
analysis. Recommend continuation of effluent monitoring for cyanide will be 2/month.

• The mercury limit of 0.04 ug/1 will be dropped based on results of the reasonable potential
analysis. Mercury monitoring will be continued in the Long Term Monitoring Plan under
Hickory's pretreatment program.
• The Bis (2-ethylhexyl) phthalate limit of 77 ug/1 will be dropped.
• The addition of color monitoring and reduction requirements based on results of AWARE
Environmental study.
This facility has been classified as a Tier 3 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.
The permittee will prepare a Pollution Prevention/Best Management Practices (BMPs)
report. This report will address the potential for the facility to reduce effluent color by
incorporating pollution prevention measures and/or BMPs prior to treatment. This report
could include an evaluation of the dyeing process, looking at the potential for dye
substitution, improving dyeing efficiencies, etc. The report could also investigate whether
any BMPs could be implemented that would reduce the amount of color discharged to the
treatment plant. The permittee could do this work independently, or request voluntary
assistance from the North Carolina Division of Pollution Prevention and Environmental
Assistance. The permittee will also prepare a Color Reduction Study, which will involve an
end -of -pipe treatment evaluation that develops cost estimates for reducing influent color by
75% and 90%. Both reports will be submitted within 24 months of the permit effective
date.
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.
ALL OTHER EXISTING PERMIT LIMITS AND MONITORING REQUIREMENTS WILL REMAIN
THE SAME.

To: Jackie Nowell
From: Valery Stephens
Date: 11/03/00
Re: Town of Hickory (NC0040797)
I did not enter RPA Data for Arsenic as all of the 20
recordings were <5 on the DMR's, and Mercury as all of the
87 recordings were <.2 on the DMR's.
The self -monitoring summary report indicated that this
facility LATE on the toxicity tests in November 1997.
