Subject: NPDES Permit Issuance
Permit No. NC0040797
Hickory Henry Fork WWTP
Catawba County
Dear Mr. Berry:
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 permit authorizes the City of Hickory to discharge up to 9.0 MGD of
treated wastewater from the Henry Fork WWTP to Henry Fork River, a class C
water in the Catawba River Basin. The permit includes discharge limitations /or
monitoring for flow, biochemical oxygen demand (BOD), total suspended solids
(TSS), fecal coliform bacteria, total residual chlorine, cyanide, chromium, lead and
chronic toxicity.
The following modifications listed in the October 26, 2005 draft permit remain
the same:
• The effluent limits for cadmium, fluoride, nickel, selenium and MBAS
have been deleted from the permit based on an analysis of submitted
effluent monitoring data, that indicated there is no reasonable potential
to exceed the water quality standard. Cadmium, fluoride, nickel, and
selenium will continue to be monitored in the Pretreatment Program's
Long Term Monitoring Plan.
• Effluent monitoring for chloride has been deleted based on the results of
the reasonable potential analysis that indicated that there was no
potential to exceed the N.C. action level standard. The twice per month
monitoring will be dropped.

• A total lead limit at a daily maximum of 34 ug/1 has been added. The
limit is based on an analysis of submitted effluent monitoring data that
indicated there is reasonable potential to exceed the water quality
standard.
• Total cyanide limits at a daily maximum of 22 ug/1 and a weekly average
of 15 ug/1 have been added. The limits are based on an analysis of
submitted effluentmonitoring data that indicated there is reasonable
potential to exceed the water quality standard.
• A total chromium limit for a daily maximum of 147 ug/1 has been added.
The limit is based on an analysis of submitted effluent monitoring data
that indicated there is reasonable potential to exceed the water quality
standard.
• Based on a review of effluent data, the submittal of a color reduction
study, and the recommendation of Division staff, the color monitoring
requirements of the City of Hickory Henry Fork have been modified. 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.
• An annual effluent pollutant scan has been added to fulfill EPA's
application requirement for major municipal wastewater treatment
facilities. Special Condition A. (4.) of this permit details this
requirement.
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.

A. (1). EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
(continued)
Notes:
3 The daily average dissolved oxygen effluent concentrations shall not be less than 5.0 mg/L.
4 The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units.
5 Limitation and monitoring requirement applies only if chlorine is added during treatment.
6 Chronic Toxicity (Ceriodaphnia) P/F @ 34%; February, May, August and November. See A. (2.).
7 The quantitation limit for cyanide shall be 10 µg/L (10 ppb). Levels reported less than 10 µg/L shall
be considered zero for compliance purposes.
8 Color samples will be analyzed for ADMI color at natural pH. Samples will be analyzed by a state
certified laboratory. See A. (3.).
9 Effluent Pollutant Scan shall be conducted annually. Refer to Condition A. (4).
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 next 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
The permittee will conduct color monitoring of instream stations (upstream, downstream) on a monthly
basis during summer season (April -October). The permittee will record whether a color plume was
observed around the outfall pipe during the monthly instream sampling events, and include that
information on the monthly discharge monitoring report. Effluent samples will be collected monthly for
color on a year-round basis. Color samples will be analyzed for ADMI color at natural pH. Effluent
samples will consist of 24-hour composites, while instream samples will be collected as grabs. Samples
will be analyzed by a state certified laboratory.
If data show that water quality standards for color are being violated by the discharge permitted by the
terms of this permit, then the Director may reopen this permit for the purpose of imposing additional
requirements pursuant to 15A NCAC 2H.0114. Alternatively, if future conditions change and color is no
longer a component of the influent wastestream, then the. permittee may request a permit modification
to remove color permit requirements.

A. (4.) EFFLUENT POLLUTANT SCAN

Hello Marshall,
Hope that you are doing well.
Regarding #1 - Our records have historically shown that bis (2-ethylhexyl)phthalate
is a laboratory contaminant and that is why is shows up in the PPAs. We have not
limited any facilities for this constituent since it is not discharged from the
facility but is added during the lab sampling process. We do not recommend a limit
or monitoring for this parameter.
#2 - Will change from "residue" to "solids"

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
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.
Hickory currently has an active pretreatment program with Long Term Monitoring Program.
There are sixteen significant industrial users (SIU) discharging to the system. The facility has
an average industrial flow of 1.6 MGD. The permitted industrial flow is 2.65 MGD.
It is recommended that the pretreatment program and Long Term Monitoring Plan be continued
during the next permit cycle.

TOXICITY TESTING:
Current Requirement: Chronic Toxicity P/F @ 34%; Feb May Aug Nov
Facility has had good record of consistently passing the toxicity test since April 2001 All
toxicity tests have been passed.
Recommendation: Renewal of existing Chronic tox test @ 34%.
REASONABLE POTENTIAL ANALYSIS:
Performed analysis on Discharge Monitoring Report data from January 2004 through July
2005 on the parameters, Arsenic, cadmium, chloride, chromium, copper, cyanide, fluoride,
lead, MBAS, mercury, molybdenum, nickel, selenium, silver, and zinc. Long term monitoring
data from the pretreatment program is included on the discharge monitoring reports. See
attached RPA results,
Results:
• The analysis of the following parameters did not show reasonable potential to exceed either
the acute or the chronic allowable concentrations. The maximum predicted concentrations
were less than the allowable concentration and therefore no limit or monitoring will be
required. These parameters will continue to be monitored quarterly in the Hickory- Henry
Fork Long Term Monitoring Plan (LTMP): Arsenic, cadmium, chloride, fluoride, MBAS,
mercury, molybdenum, nickel and selenium. (The existing limits for cadmium,
fluoride, MBAS, nickel and selenium will not be renewed.)
• The analysis of the following parameters did show reasonable potential to exceed the NC
action level, however per NCDWQ procedure for action level standards, no limit will be
recommended. In addition there are no chronic toxicity problems with the facility. It is
recommended that 2/month monitoring remain in the permit for these parameters: Copper,
silver and zinc.
• The analysis of the following parameters did show reasonable potential to exceed both the
acute and/or the chronic allowable concentrations. The maximum predicted
concentrations were greater than the allowables and therefore a limit will be required.
• A weekly average limit of 147 ug/1 for chromium.

• A weekly average limit of 15 ug/1 and a daily maximum limit of 22 ug/1 for cyanide.
• A weekly average limit of 73 ug/1 for lead.

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), pH, fecal coliform,
COD, conductivity, NH3, TSS, and color. Reviewed instream data for months of April through
October for years 2002 through 2005. Most instream data was greater than the DO standard
of 5.0 mg/1 below the discharge. There were few exceedances of fecal coliform standard of
200/ 100m1, either upstream or downstream of the Hickory discharge.
Recommendation: continuation of instream monitoring for temperature, dissolved
oxygen, fecal coliform and conductivity.

PROPOSED CHANGES:
The following modifications have been made to the permit:
• Existing limits for Cadmium, Fluoride, Nickel, and Selenium were dropped from the permit.
Results of the analysis showed that there was no longer reasonable potential to exceed the
allowable concentration.
• The limit for MBAS was dropped based on the NC water quality standard being modified
and the MBAS standard applies only to water supply classifications. The receiving stream,
Henry Fork, is a class C. Will recommend monitoring for MBAS
Hickory -Henry Fork WV\V'I'P 1=act. Sheet

Page 3

• A chromium weekly average limit of 147 ug/1 will be added based on results of the
reasonable potential analysis. The maximum predicted concentration exceeded the chronic
allowable concentration.
• A lead weekly average limit of 73 ug/1 will be be added based on results of the reasonable
potential analysis. The maximum predicted concentration exceeded the chronic and the
acute allowable concentrations.
• A weekly average limit of 15 ug/1 and a daily maximum limit of 22 ug/1 for cyanide will be
added based on results of the reasonable potential analysis. The maximum pre predicted
concentration exceeded the chronic and the acute allowable concentrations.
• Effluent and instream color monitoring will continue. 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 outran 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.
ALL OTHER EXISTING PERMIT LIMITS AND MONITORING REQUIREMENTS WILL REMAIN
THE SAME.

monies were used in the construction of this facility.
2. Special monitoring or additional limits requests: None have been requested at this time.
PART IV - EVALUATION AND RECOMMENDATIONS
The City of Hickory requests reissuance of the subject permit. There have been no changes to
the WWTP during the current permit term; however, there has been one modification to the NPDES
permit (addition of a weekly average limit for ammonia) since the permit was last renewed. There are
also additions to the WWTP's unit processes that were not included in the permit during the last
renewal (See Part II, No. 2).
During the term of the current permit, this facility was designated as a Tier 3 color discharger
due to the presence of a significant amount of color in the effluent. Since that time, effluent color has
been substantially reduced due to inproved color removal through adjustments in the biological
treatment process, and the closure of several of the industrial facilities that discharged colored
wastewater to the City's collection system. As a result of both the operational adjustments and the
elimination of the color producing sources, observed effluent color levels are such that a reevaluation
of the WWTPs position as a Tier 3 color discharger is recommended.
It is recommended that the NPDES permit be renewed as requested.

1. For bis (2-ethylhexyl)phthalate, the permit

EPA's organism only human health criterion is 5
be a limit for this parameter in the permit?
thanks Marshall
appl indicates an avg
based on 3 samples.
.9 ug/1. shouldn't there
2. In footnote 2 in A.1, recommend changing "total suspended residue" to
"total suspended solids".
Hello Marshall,
Hope that you are doing well.
Regarding #1 - Our records have historically shown that bis (2-ethylhexyl)phthalate
is a laboratory contaminant and that is why is shows up in the PPAs. We have not
limited any facilities for this constituent since it is not discharged from the
facility but is added during the lab sampling process. We do not recommend a limit
or monitoring for this parameter.
#2 - Will change from "residue" to "solids"

Hickory City Henry Fork WWTP
Hickory, North Carolina
HSMM Commission No. 60467
Dear Mrs. Bryant:
The City of Hickory's Henry Fork Wastewater Treatment Plant processes all of its sludge by
composting. Sludge is removed from the primary and secondary clarifiers and placed in a tanker
truck for transport to the Hickory Regional Compost Facility in Newton, NC, for further
processing into compost material. During the composting process, the sludge is stabilized
sufficiently to meet all vector attraction and pathogen reduction requirements. Once dry, the
cured compost is distributed to various entities to be used as a soil amendment.
If additional information is needed, please feel free to contact me at [phone].
