Subject: Final NPDES Permit Renewal
Permit NC0020401
Northeast WWTP
Catawba County
Class IV Facility
Dear Mr. Berry:
Director
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between
North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently
amended).
The following modifications were made to the draft permit of June 14, 2016.
• The Division has updated the guidance for NPDES implementation of Ammonia Criteria in July,
2016 following the approval of Triennial Review of Water Quality Standards (2007-2014) by
EPA in April, 2016. Monthly and weekly average limits for ammonia nitrogen have been added
to the final permit using the NH3/TRC Waste Load Allocation spreadsheet to protect receiving
waters from ammonia toxicity.
• Quarterly monitoring for cadmium and silver was added to the final permit. The Division
guidance for water quality standards for hardness dependent dissolved metals requires permittees
to monitor cadmium and silver at their Practical Quantification Level (PQL) i.e. 0.5 and 1.0 µg /1
respectively. Northeast WWTP is currently reporting cadmium at 1.0 µg/I and silver at 5 µg/1.
Hence, quarterly monitoring requirements at PQL were added for these two metals in the final
permit. Footnotes 7 and 8 were added to A. (1) Effluent Limitations and Monitoring
Requirements in Part I to report effluent lab test results at PQL level. Footnote 6 was also updated
to coincide sampling for cadmium and silver with the sampling for hardness and other metals.
This final permit contains the following changes from your previous permit:
• The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Commission (EMC) on November 13, 2014. The US EPA
subsequently approved the WQS revisions on April 6, 2016 with some exceptions. The NC
Division of Water Resources NPDES Permitting Unit is required to implement the new dissolved
metal standards in all permits public noticed after April 6, 2016.

Page 12
The new standards for most metals include acute standards. Further, the freshwater standards for
several metals are expressed as the dissolved form of the metals, and seven metals have hardness -
dependent equations. As a result, the NPDES Permitting Unit will need site -specific effluent
hardness data and instream hardness data, upstream of the discharge, for each facility monitoring
these metals in order to calculate permit limitations. Effluent hardness has been added to this
permit at a quarterly monitoring frequency. Footnote 7 was added to A. (1) Effluent Limitations
and Monitoring Requirements in Part I to require hardness sampling in conjunction with metal
sampling.
• As a result of Reasonable Potential Analysis, effluent monitoring requirement for cyanide was
removed as this parameter did not show any reasonable potential to violate the quality of water in
the Catawba River.
• Bis (2-ethylhexyl) phthalate was detected in one of the PPAs. This parameter showed reasonable
potential to violate water quality. Quarterly monitoring requirements were added to the permit due
to limited data set and none of the PPA results were greater than the allowable concentration for
this parameter.
• Daily effluent monitoring requirements for conductivity were added to the permit as the facility
receives wastewater from industrial dischargers as well.
• Instream monitoring of fecal coliform was removed as Catawba River is not impaired for fecal
coliform as per 303d list published in 2016.
• Sampling frequency for effluent pollutant scan was modified to three times during the permit
cycle. Special condition A.(3) was also modified to include narrative for additional toxicity test
requirements for permit renewal.
• The facility is required to continue implementing the Mercury Minimization Plan (MMP) in the
next permit period. Special condition A. (4) was modified to include narrative for this requirement.
• Starting December 21, 2016, federal regulations require electronic submittal of all discharge
monitoring reports (DMRs) and specify that, if a state does not establish a system to receive such
submittals, then pennittees must submit DMRs electronically to the Environmental Protection
Agency (EPA). The final NPDES Electronic Reporting Rule was adopted and became effective
on December 21, 2015.
The requirement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) intemet application has been added to your
fmal NPDES permit. [See Special Condition A. (5)] For information on eDMR, registering for
eDMR and obtaining an eDMR user account, please visit the following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr.
For more information on EPA's final NPDES Electronic Reporting Rule, please visit the
following web site: http://www2.epa.gov/compliance/final-national-pollutant-discharge=
elimination-system-npdes-electronic-reporting-rule.
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
fmal 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 Resources or any other Federal,
State, or Local governmental permits that may be required.

A. (2) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
[15A NCAC 02B .0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 13%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent versions
or "North Carolina Phase 11 Chronic Whole Effluent Toxicity Test Procedure" (Revised- December 2010) or
subsequent versions. The tests will be performed during the months of January, April, July and October.
These months signify the first month of each three-month toxicity testing quarter assigned to the facility.
Effluent sampling for this testing must be obtained during representative effluent discharge and 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 -December 2010) 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, DWR Form AT-3 (original) is to be sent to the
following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center

facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to additional
toxicity testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5) and EPA Municipal
Application Form 2A. The US EPA requires four (4) toxicity tests for a test organism other than the test species
currently required in this permit. The second species tests should be conducted either quarterly for a 12-month
period prior to submittal of the permit renewal application, or four tests performed at least annually in the four
and one half year period prior to the application. The second species tests must be multiple concentration (5
concentrations plus the control). These tests shall be performed for acute or chronic toxicity, whichever is
specified in this permit. POTWs performing NPDES chronic Ceriodaphnia testing should perform chronic
Fathead minnow testing. POTWs performing NPDES acute Fathead Minnow testing should perform acute
Ceriodaphnia testing. POTWs performing NPDES chronic Mysid shrimp testing should perform chronic
Silverside Minnow testing.
The second species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following
address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the additional

NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted
electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and
submit DMRs electronically using the internet. Until such time that the state's eDMR application is
compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be
required to submit all discharge monitoring data to the state electronically using eDMR and will be required
to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the
computer printed eDMR to the following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being
physically located in an area where less than 10 percent of the households have broadband access, then a
temporary waiver from the NPDES electronic reporting requirements may be granted and discharge
monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or alternative forms approved by
the Director. Duplicate signed copies shall be submitted to the mailing address above. See "How to Request
a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a Waiver
from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of each
electronic submission. The permittee should use the EPA's website resources to identify the initial recipient
for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity (EPA or
the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving
electronic NPDES data [see 40 CFR 127.2(b)].

I. SUMMARY
The Northeast Wastewater Treatment Facility, one of the three WWTPs of the City of Hickory is currently
serving a population of 23410. The plant is designed to treat 6.0 MGD of domestic and industrial
wastewater. The annual average daily flow rate varied from 2.83 to 3.03 MGD from 2012 to 2014. The
city has a separate sewer system. The plant consists of bar screens, influent lift station, grit removal
system, anaerobic and anoxic basins, oxidation ditches, secondary clarifiers, chlorination / dechlorination
system, aeration, belt thickeners and holding tanks for sludge. It treats domestic and industrial wastewater
before discharging it to the Catawba River (Lake Hickory).
The facility has a full pretreatment program and a Long Term Monitoring Program (LMTP) as it receives
flow from 5 non -categorical Significant Industrial Users (SIUs). The permitted industrial flow is 0.367
MGD and the actual flow was 0.314 MGD in 2013-14. The facility should continue to implement the
pretreatment program in the next permitting cycle.
II. RECEIVING STREAM
The receiving stream is the Catawba River (Lake Hickory) which is classified as WS-V and B at the
discharge point in Upper Catawba watershed in the Catawba River Basin. Lake Hickory is a runoff river
impoundment located between Lake Rhodhiss and Lookout Shoals Lake on the Catawba River. Lake
Hickory in sub basin 03-08-32 is not listed in 2016 303d impaired streams list.

B. Compliance History
The compliance history from January, 2013 to February, 2016 was also reviewed. The facility had
received two notices of violation for not meeting the TSS limits during this period. No actions were taken
in April, 2013 for exceeding weekly average limit for TSS as the mitigating actions taken by the permitee
were found satisfactory. In 2014, the facility received the notice of violation for not meeting weekly
average limit for TSS. DWR took the enforcement actions for this violation and the facility paid penalty
for noncompliance. The compliance inspection was conducted in January, 2015. The facility was found
compliant with the NPDES permit requirements.
C. Mercury Evaluation
A mercury evaluation was conducted in accordance with the permitting guidance developed for the
implementation of the statewide Mercury TMDL to determine the need for a limit and/or Mercury
Minimization Plan (MMP). Table 2 summarizes the available mercury data used to determine permit
limit.

Page 2 of 6

The water quality based effluent limitation (WQBEL) for mercury is 89.4 ng/1 and the technology
based effluent limit (TBEL) is 47 ng/1. None of the annual averages exceeds the WQBEL or
TBEL. Therefore, no limit will be implemented as per mercury TMDL guidance. However, all
the mercury sample results were above 1 ng/1 during previous permit period. Since, this is a major
municipal facility with greater than 2 MGD flow, the city is required to continue implementing its
existing MMP.
The current MMP includes recycling of fluorescent lamps, batteries and mercury containing
products. The City of Hickory surveyed all the SIUs in 2015 and area industries in 2013 to
identify the potential sources of mercury. SIUs discharging their wastewater to the Northeast
WWTP including the hospitals were monitored for lower level of mercury on yearly basis. Other
control measures included organizing residential hazardous waste collection events, collaborating
with the Catawba county to collect electronics and hazardous household wastes at the landfill and
disposing off mercury thermometers through a waste disposal service. The city will continue
mercury monitoring as a part of its Pretreatment Long Term Monitoring Program (LIMP)
D. Priority Pollutant Analysis (PPA)
The facility had included results of three priority pollutant analyses (2011-2013) in the permit renewal
application. Additional 3 PPA results from 2014-2016 were also reviewed to investigate the presence of
priority pollutants in the effluent. Metals such as copper, lead, mercury, cyanide and zinc, total phenolic
compounds, chloroform, dichlorobromomethane and bis (2-ethylhexyl) phthalate were detected in the
effluent pollutant scans. A reasonable potential analysis was conducted for these parameters. None of
these parameters except bis(2-ethylhexyl) phthalate showed reasonable potential to violate the state's
water quality standard. Effluent monitoring requirements were added for bis(2-ethylhexyl) phthalate due
to limited data set and none of the sample results were higher than the allowable concentration (See RPA
results).
E. Reasonable Potential Analysis
With the approval of Triennial Review (2007-2014) of the NC Water Quality Standard (WQS) by
the NC Environmental Management Commission (EMC) in 2014 and US -EPA (with some
exclusions) on April 6, 2016, NPDES Permitting Unit of the NC Division of Water Resources is
required to implement the new dissolved metal standards in all permits public noticed after April
6, 2016.
A reasonable potential analysis using the updated NC WQS was conducted on effluent toxicant data
collected between January, 2013 and February, 2015. Based on this analysis, the following permitting
actions are proposed for this permit:
• Monitoring Only: The following parameters will receive a monitor -only requirement since they
did not demonstrate reasonable potential to exceed applicable water quality standards/criteria, but
the maximum predicted concentration was >50% of the allowable concentration: Copper, Zinc
and Bis (2-ethylhexyl) phthalate
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring, since
their concentration was below detection level or their maximum predicted concentration was
<50% of the allowable concentration: Arsenic, Cadmium, Chloroform, Chromium, Cyanide,
Lead, Molybdenum, Nickel, Selenium, Silver, Total Phenolic Compounds and
Dichlorobromomethane. The facility will continue monitoring of these heavy metals under
pretreatment LTMP. (See attached spreadsheet with RPA results)
Page 3 of 6

F. Aquatic Toxicity Testing
Permit holder is required to perform quarterly Whole Effluent Toxicity (WET) tests using Ceroidaphnia
Dubia at an effluent concentration of 13%. Total 13 WET tests were performed from January, 2013 to
February, 2016. The facility passed all the toxicity tests. The permit renewal application included four
second species toxicity tests with passing results.
G. Instream Monitoring
The permittee is required to monitor dissolved oxygen, temperature and conductivity upstream and
downstream of the discharge point in the next permit cycle. It also requires to collect upstream hardness
data on quarterly basis to calculate the permit limitations for hardness dependent dissolved metals.
The upstream monitoring station is located at NC Hwy 127 Bridge and downstream station is one mile
south of the outfall. Instream data was reviewed from January, 2013 to February, 2015. The facility had
collected samples for temperature, DO, pH, fecal coliform and conductivity. It was observed that pH
remained between 6 to 9 S.U. and DO was above 6 mg / 1 in all the upstream and downstream samples. It
was observed that fecal coliform count was higher during the summer months in 2013 and 2015 and in
September and November in 2014. However, the effluent fecal coliform counts were within permit limit.
Therefore, the discharge from the facility is not responsible for higher fecal coliform counts in the
Catawba River which currently is not impaired for fecal coliforms.

Addendum to the fact sheet
Following changes were made to the draft permit.
1. Monthly and weekly average limits for ammonia nitrogen have been added to the final
permit as per the updated guidance for NPDES implementation of Ammonia Criteria.
These limits i.e. 6 µg/1 and 18 14/1 were calculated using the waste load allocation (WLA)
spreadsheet to protect receiving waters from ammonia toxicity.
2. Quarterly monitoring requirements were added for cadmium and silver in the final permit
according to the Division guidance for water quality standards for hardness dependent
dissolved metals. Northeast WWTP's reporting levels for cadmium and silver are < 1 µg/1
and < 5 µg /1 respectively. The permittee is required to report the results at the Practical
Quantification Level (PQL) i.e. 0.5 µg/1 for cadmium and 1.0 µg/1 for Silver. Footnotes 7
and 8 were added to A. (1) Effluent Limitations and Monitoring Requirements in Part I to
report effluent lab test results at PQL level. Footnote 6 was also updated to coincide
sampling for cadmium and silver with the sampling for hardness and other metals.

PROCESS FLOW NARRATIVE
NORTHEAST WWTP, NC0020401
PERMIT RENEWAL — CATAWBA BASIN
The Northeast Wastewater Treatment Facility is a secondary treatment plant utilizing the Oxidation
Ditch process. The Plant is designed to treat 6.0 MGD of municipal and industrial wastewater flows from
served areas in Northern Hickory and Southern Alexander County. The plant is equipped with two back-
up generators that are designed to run all plant processes in case of power failure.
Flow enters the plant via a 42-inch gravity sewer line and immediately enters a main channel which
splits into two parallel channels, each containing an automatic mechanical bar screen. After flowing
through the bar screens the two channels rejoin and flow through a parshall flume, which provides
measurement of the influent, before entering the influent lift station. The influent lift station pumps
sewer to the headworks structure containing the grit removal system. Wastewater flows from the grit
removal system and enters one of two oxidation ditches equipped with aeration equipment. The
oxidation ditch is a three stage ditch, designed for biological nutrient removal. Wastewater overflows
the effluent weir gate and enters a splitter box before being routed to secondary clarifiers. Settled
sludge is pumped from the clarifiers to the oxidation ditch as return activated sludge or to the truck
loading station as waste activated sludge from the RAS/ WAS pump station. Effluent from the clarifiers
flows to the chlorine contact chamber for chlorination. At the end of the chlorine contact chamber
sulfur dioxide is added prior to post aeration. The effluent then discharges into the outfall line and is
diffused before it is released into the receiving stream.
