Subject: Final NPDES Permit Renewal
Permit NCO020401
Northeast W WTP
Catawba County
Grade IV Biological WPCS
SIC Code 4952
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 change was made to the draft permit sent to you on March 24, 2021:
• The parameter code for Chronic Toxicity was corrected to TGP3B; see A. (l.).
The Division acknowledges the updated low flow 7Q10 of 100 cfs for the receiving water based
on the minimum flow release according to the FERC relicensing agreement of 2006 and its
Revision 2 of 2018. However, the original estimate of 60 cfs was used in limit development in
order to avoid backsliding, which is prohibited under Sections 402(o)(2) and 303(d)(4) ofthe CWA
and federal regulations under 40 CFR 122.44(I).
The final permit maintains the following significant changes identified in the letter sent on
March 24, 2021:
a Based on the reasonable potential analysis (RPA) showing no reasonable potential to
violate state water quality standards, the monitoring requirements for -Total Cadmium and Total
Silver have been removed from the permit [See A. (I.)].
a Based on NPDES guidance regarding the reduction of monitoring frequencies in NPDES
permits for exceptionally performing facilities, monitoring requirements for BOD,, NM-N,
Total Suspended Solids and Fecal Coliform have been reduced to twice per week [See A.

• The City of Hickory reported Bis (2-ethylhexyl) phthalate at less than detection of all
samples tested, among which one was at detection level < 50.0 µg/L and another at < 25.0
µg/L in the DMR results). The City's allowable discharge concentration for Bis (2-ethylhexyl)
phthalate is 8.1 µg/L. DWR's laboratory identifies the target Practical Quantification Limit
(PQLs) for Bis (2-ethylhexyl) phthalate as 10.0 µg/L. 15A NCAC 2B .0505 (e) (4) requires
that all test procedures must produce detection and reporting levels that are below the permit
discharge requirements and all data generated must be reported to the approved detection level
or lower reporting level of the procedure. If no approved methods are capable of achieving a
detection level below the permit discharge requirement (or allowable discharge concentration)
the method with the lowest detection level must be used. The City should use sufficiently
sensitive test methods for all pollutants, including when performing Effluent Pollutant Scans.
Quarterly monitoring for Bis (2-ethylhexyl) phthalate has been maintained.
Instream monitoring parameters have been removed from the Effluent sheet [A. (I.)] and
placed as a separate Special Condition [See A. (2.)].
• Some of the wording has changed in Special Condition A. (3.), Chronic Toxicity Permit
Limit, please review each paragraph carefully.
• Special Condition A. (4.) has been modified to include the specific three years in which
the Effluent Pollutant Scan shall be performed (2023, 2024, and 2025).
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and program reports. The requirement to continue reporting discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet
application has been added to your NPDES permit [See A. (5.)].
A notation was made concerning the Electronic Reporting Rule — NPDES Electronic
Reporting Rule — Phase 2 Extension. EPA extended the Phase 2 deadline to December 21,
2025 [See A. (5.)].
Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
and Instream Monitoring Requirements [See A. (I.) and A. (2.), respectively].
• Regulatory citations have been added to the permit.
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 ofthis letter. This request must be in the form of written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714).
Unless such demand is made, this decision shall be final and binding.
The NPDES standard conditions (Parts 11, 111, and IV) that are a part of the permit are not included
in this document (cover, map, and Part 1). The conditions are the same as in your previuos permit
except that agency and division names have been updated. The latest version is available at
https://bit.ly/3k5NFal. and can be viewed online or downloaded as a PDF file.
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 regulations.

A. (3.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) [15A NCAC 02B .0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriadaphnia 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 H 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 electronically using the
Division's eDMR system 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:

Or, results can be sent to the email, ATForns.Al'B nc lenrg_ov
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the pennittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the
facility name, permit number. pipe number, county, and the month/year of the report with the notation of "No
Flow" in the comment area of the form. The report shall be submitted to the Water Sciences Section at the address
cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month. Assessment of toxicity compliance is based on the toxicity testing quarter,
which is the three month time interval that begins on the first day of the month in which toxicity testing is required
by this permit and continues until the final day of the third month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Resources indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include
alternate monitoring requirements or limits.

Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)I
The Permittee shall report discharge monitoring data electronically using the 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 monthly electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. The eDMR system may be
accessed at: https://deci.nc.gov/about/divisions/water-resources/edmr.
If 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. I, 2, 3) or alternative
forms approved by the Director. Duplicate signed copies shall be submitted 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
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 and continue monthly, or in the case of a new facility, on the last day of
the month following the commencement of discharge.
Starting on December 21, 2025, 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.

Permit NCO020401
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(I)(9), the pennittee 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)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at:
https://www.federalrepister.gov/documents/2015/ 10/22/2015-24954/national-pollutant-discharge-
el imination-system-nodes-electronic-reporting-rule.
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Reauest a Waiver from Electronic Reporting
The Permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a pennittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data
and reports shall be submitted electronically to the Division unless the pennittee re -applies for and
is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
kitty://deci.nc.pov/about/d iv i sions/water-resources/ed n1 r.
4. Signatory Requirements ISupplements Section B. 0I.) (b) and Supersedes Section B. 01.) (d)I
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part
11, Section B. (I I .)(a) or by a duly authorized representative of that person as described in Part 11,
Section B. (1 I.)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.

PART 1V
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [I 5A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [I 5A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that (I 5A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
Section C. Municipal Control of Pollutants from Industrial Users.
Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
2. Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which
cause or contribute to Pass Through or Interference as defined in 15A NCAC 02H .0900 and 40 CFR 403. [40
CFR 403.5(a)(1)]

Footnote.
1. 'I he fact sheet for the 2016 permit lists an estimated 7Q 10 of 60 cfs and estimated average flow of 225 cfs.
These flow estimates were first established in the 2011 permit tact sheet based on the historical minimum
release of 40 cfs from the dam below Lake Rhodhiss and estimated flows of —20 cfs at the mouths of
Gunpowder Creek and Little River, in consideration that the Federal Energy Regulatory Commission (FERC)
license for the Catawba River dams had not been renewed. and updated minimum releases were not final at
that time. The FERC Catawba-Wateree Hydro Project relicensing agreement had since been finalized in
December 2006, with an amended Revision 2 of the agreement approved by FERC in January 2018. The
average river flow in Lake Hickory is 1,307 MGD (843 cfs) according to the 2006 agreement (Appendix H),
and the critical flow is 100 cfs per Revision 2 (p. C-6). These updated flows are cited here but are not applied
in permit limit development in order to comply with anti -backsliding regulations.
The receiving water of Catawba River (Lake Hickory) is meeting all criteria per the 2018 NC Integrated
Report. This segment of the Catawba River is classified both as a waterbody used for primary recreation
(e.g.. swimming) (Class B) and a water supply water (Class WS-IV). The receiving water is in a critical
area for water supply (Subclass CA) as it lies within '/, mile of the Lake Hickory water supply intake per
15A NCAC 02B .0202 (19).

High BOD and TSS values on April 24. 2017 are associated with high rainfall according to notes on that
month's DMR. A low pH value of 5.8 was recorded in October 2017. determined not to be representative
of the actual effluent pH after investigation with lab control pH meters.
4. Instream Data Summary
Instream monitoring may be required in certain situations, for example: I ) to verify model predictions when
model results for instream DO are within I mg/L of instream standard at full permitted flow; 2) to verify
model predictions for outfall diffuser; 3) to provide data for future TMDL; 4) based on other instream
concerns. Instream monitoring may be conducted by the Permittee, and there are also Monitoring Coalitions
established in several basins that conduct instream sampling for the Permittee (in which case instream
monitoring is waived in the permit as long as coalition membership is maintained).
/fapplicable, summarize anj, instream data and what instream monitoring trill be proposed for this permit
action: The 2016 permit required instream monitoring for Dissolved Oxygen (DO). Temperature and
Conductivity. In addition, instream Total Hardness monitoring, upstream of the discharge, was added to the
permit in 2016 to calculate dissolved metals limits via Reasonable Potential Analysis (RPA; see Section 6
below). Instream monitoring locations in the current permit include one upstream at the NC Hwy 127 bridge
and one downstream at about 1 mile from the outfall.
Instream data from January 2017-December 2020 were obtained from submitted DMR reports and
compared against state water quality standards where applicable. As the data were sampled synchronously
at both locations, up- to downstream differences were tested by paired two -sample t-test for means. Instream
data review findings for each parameter are summarized in Table 2 below.

I. For water supply waters (Class WS I - IV).
Dissolved O.x gen (DO) - DO remains in the permit as a parameter of concern for aquatic life. Reviewed
instream DO data showed near constant readings of 6.5 mg/L from January to May 2017. which was due
to a technician issue that was resolved according to the facility lab supervisor. Seasonal patterns of summer
lows and winter highs were evident after this period. Upstream summer minima were above the 5 mg/L
daily average water quality standard for non -trout waters (15A NCAC 02B .021 1): however, downstream
minima were below it in 2017, 2018 and 2019 with I, 1 and 3 occurrences in the respective years. All
relevant effluent data (DO. BOD. Ammonia and Fecal Colifonn) ofthe individual days of low downstream
DO were not outside their permit limits (Table 3). Statistically significant differences were detected
between average DO values of the two instream locations. Concurrent effluent DO appeared on average
lower than either up- or downstream DO but with no occurrences below the stream standard.

Temperature - Temperature remains in the permit as a parameter of concern for aquatic life. Reviewed
instream temperature data showed seasonal patterns of summer highs and winter lows at both locations.
Summer temperature maxima exceeded the water quality standard of 29°C for upper piedmont and
mountain waters (15A NCAC 02B .021 I) at both locations in 2017, 2018 and 2019. Statistically significant
differences were detected between average temperature values of the two instream locations. Review of
paired up- to downstream temperatures found no exceedances of the 2.8°C increase standard (15A NCAC
02B .0211). The concurrent effluent temperatures averaged lower overall than either up- or downstream
temperatures. but with higher winter minima. the effluent does not appear to affect the receiving stream
temperature.
Conductivi0, Conductivity remains in the permit as a parameter of concern due to industrial discharges;
the WWTP has a pretreatment program with 5 SIUs. Reviewed instream conductivity data found
statistically significant differences in averages of the two instream locations. Concurrent effluent
Conductivity data averaged substantial ly higher than either instream conductivity. Comparisons of the three
data sets suggest that the effluent may be impacting the instream conductivity.
Fecal C'olif n-nt was removed from the instream monitoring requirements in the 2016 permit as the receiving
water was not impaired for Fecal C'olifornt and effluent concentrations were within permit limits. The
receiving water is a Class B waterbody. which would require instream monitoring according to Division
guidance. However, the receiving water remains unimpaired, and review of effluent Fecal Coliform data
found them to be well within the limits with an overall geometric mean oft cfu/l00 mL. Therefore, instream
monitoring for Fecal Coliform is not needed and was not added to the permit.
Total Hardness is in the permit at upstream only to aid in calculating total metals in RPA (see Section 6
below). However, there is an instream standard of 100 mg/L for water supply (Class WS) waters, and the
receiving stream is classified WS-I V. While both the upstream and effluent data are well below the standard.
the effluent's impact potential is assessed via RPA and found no reasonable potential to exceed the instream
standard (see Section 6 below).
No changes were made to instream requirements.
Is this facility a member of a Monitoring Coalition with waived instream monitoring (YIN): NO.
Name of Monitoring Coalition: N/A.

6. Water Quality -Based Effluent Limitations (WQBELs)
Dilution and Mixing Zones
]it accordance with 15A NCAC 213.0206, the following streamflows are used for dilution considerations
for development of WQBELs: I Ql0 streamflow (acute Aquatic Life); 7Q10 streamflow (chronic Aquatic
Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH).
Ijapplicable, describe any other dilution factors considered (e.g., based on CORMLYmodel results): NA.
Ifapplicable, describe ani, mixing zones established in accordance with 15A NCAC 1B.0204(b): NA.
Oxygen -Consuming Waste Limitations
Limitations for oxygen -consuming waste (e.g., BOD) are generally based on water quality modeling to
ensure protection of the instreatn dissolved oxygen (DO) water quality standard. Secondary TBEL limits
(e.g., BOD = 30 mg/L for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.
If permit limits are more stringent than TBELs, describe hot, limits were developed: Year-round BOD
limits in the 2016 permit are based on the TBEL of 30/45 mg/L monthly average/weekly average. The
original BOD limit of 30 mg/L was recommended from a lake model run in 1983. The current limits are
maintained in the permit.
Ammonia and Total Residual Chlorine Limitations
Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of
1.0 mg/L (summer) and 1.8 mg/L (winter). Acute ammonia limits are derived from chronic criteria, utilizing
a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non -Municipals.
Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection
of aquatic life (17 µg/L) and capped at 28 µg/L (acute impacts). Due to analytical issues, all TRC values
reported below 50 µg/L are considered compliant with their permit limit.
Page 6 of 14

Describe any proposed changes to anononia and/or TBC limirs.lor this permit renewal: Ammonia limits
in the 2016 permit are toxicity -based, first placed in the permit in 2016. Ammonia was reviewed in the
attached Wasteload Allocation (WLA) sheet using the now design of6.0 MGD and receiving stream low
floss of 7Q10 = 60 efs (estimate). The updated 7Q10 of 100 efs was not used to avoid backsliding. The
resulting allowable concentrations were found to be as protective of ammonia toxicity as the current ones.
The current limits are maintained in the permit.
WLA calculations for 1'RC cap the allowable concentration at 28 µg/l., same as the 2016 permit limit. This
limit is maintained in the permit.
Reasonable Potential Analysis (RPA) for Toxicants
Ifopplicable, conduct RPA analysis and complete information below.
The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality
standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent
effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The NC
RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of zero
background; 3) use of '/2 detection limit for "less than" values; and 4) streantflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Insn-earn Dissolved Metals Standards, dated June 10, 2016.
Effluent and upstream Total Hardness monitoring requirements are in the 2016 permit to aid in calculating
effluent metals limits for hardness -dependent dissolved metals per the 2016 Division guidance document.
Submitted DMR data were reviewed for use in the RPA, finding the average upstream Total Hardness =
14.8 mg/l, (range: 12.0-18.1 mg/L; sample size = 17). Since this average is below the default value of 25
mgrL Total Hardness, the default value was used for upstream hardness in the RPA.
A reasonable potential analysis was conducted on effluent toxicant data collected from January 2017
through December 2020. Pollutants of concern included toxicants with positive detections and associated
water quality standards/criteria. Based on this analysis, the following permitting actions are proposed for
this permit:
• Effluent Limit with Monitoring. The following parameters will receive a water quality -based
effluent limit (WQBEL) since they demonstrated a reasonable potential to exceed applicable water
quality standards/criteria: None.
• Monitorine 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-.
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring, since
they did not demonstrate reasonable potential to exceed applicable water quality standards/criteria
and the maximum predicted concentration was < 50% of the allowable concentration: Arsenic,
Berrilimn. Cadmium, Toted Chromium, Total Phenols, ('vanide, Lead, llohhcknuln, Nickel,
.Selenium. Silver.
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for
additional pollutants of concern.
o The following parameter(s) will receive a water quality -based effluent limit (WQBEL)
with monitoring, since as part of a limited data set, two samples exceeded the allowable
discharge concentration: None.
o The following parameter(s) will receive a monitor -only requirement, since as part of a
limited data set, one sample exceeded the allowable discharge concentration: None.
o The following detected parameters will not receive a limit or monitoring, since they did
not demonstrate reasonable potential to exceed applicable water quality standards/criteria
Page 7 of 14

and the maximum predicted concentration was < 50% of the allowable concentration:
Broniglbrm, Chloroform. Dichlorohromonuetuane, Toluene.
If applicable, attach a spreadsheet of the RPA results as well as a coPy of the Dissolved Metals
Implementation Fact Sheet.for,fi•eshwater/saltwater to this Fact .Sheet. Include a printout of the RPA
Dissolved to Total Metal Calculator sheet if this is a Municipality with a pretreatment Program.
Toxicity Testing Limitations
Permit limits and monitoring requirements for Whole Effluent Toxicity (WET) have been established in
accordance with Division guidance (per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits
issued to Major facilities or any facility discharging "complex" wastewater (contains anything other than
domestic waste) will contain appropriate WET limits and monitoring requirements, with several exceptions.
The State has received prior EPA approval to use an Alternative WET Test Procedure in NPDES permits,
using single concentration screening tests, with multiple dilution follow-up upon a test failure.
Describe proposed toxicity test requirement: The facility is a Major POTW with a chronic WET limit at
13% effluent, which will continue at a quarterly frequency. The WET limit is based on the Instream Waste
Concentration (I WC) as calculated from the design flow of 6.0 MGD and the receiving stream 7Q 10 of 60
cfs (NIET Perminitw Limits and Monitoring Requirements guidance memo. 8/2/1999). The updated 7Q10
of 100 cfs was not used to avoid backsliding.
Mercury Statewide TMDL Evaluation
There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply with
EPA's mercury fish tissue criteria (0.3 mg/kg) for human health protection. The TMDL established a
wasteload allocation for point sources of 37 kg/year (81 lb/year), and is applicable to municipals and
industrial facilities with known mercury discharges. Given the small contribution of mercury from point
sources (-2% of total load), the TMDL emphasizes mercury minimization plans (MMPs) for point source
control. Municipal facilities> 2 MGD and discharging quantifiable levels of mercury (> I ng/L) will receive
an MMP requirement. Industrials are evaluated on a case -by -case basis, depending if mercury is a pollutant
ofconcem. Effluent limits may also be added if annual average effluent concentrations exceed the WQBEL
value (based on the NC WQS of 12 ng/L) and/or if any individual value exceeds a TBEL value of 47 ng/L.
Describe proposed permit actions based on mercho7, evaluation: A Mercury Minimization Plan (MMP)
special condition is in the 2016 permit. Submitted low level mercury data from January 2017 through
December 2020 were reviewed for TMDL evaluation. All data except one were detected with no annual
averages exceeding the TBEL of 47 ng/L and no individual values exceeding the WQBEL of 89.42 ng/L
(Table 5). Because the design flow is > 2 MGD and mercury was detected (> I ng/L) in the effluent. an
MMP is required. The MMP special condition has been reworded toward its maintenance.

Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Ntnrient Management Strategies and their implementation within
this permit: NA.
Page 8 of 14

Other WOBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs: The receiving water is
classified WS-IV, and is subject to instream water supply -related standards for the following parameters:
Bis (2-ethylhexyl) phthalate. Nitrate -Nitrogen (NO N) and Total Hardness. A supplemental RPA was run
for these parameters, yielding the following results: a reasonable potential was found for Bis (2-ethylhexyl)
phthalate but not for Nitrate -Nitrogen or Total Hardness. The reasonable potential found was based on two
high non -detects (among all data that were non -detects); quarterly monitoring for Bis (2-ethylhexyl)
phthalate is maintained with a note to test and report to the lower reporting level of the procedure.
In addition, chlorinated phenols, to which a standard of I µg/L for WS waters applies, was addressed via
review of the effluent data. Review of the three PPAs yielded no detects of any individual chlorinated
phenols tested (2-Chlorophenol. 2.4-Dichlorophcnol. Pentachlorophcnol, 2.4.6-Trichlorophcnol), each at <
5 µg/L. No changes are proposed regarding chlorinated phenols. No other changes were made regarding
these parameters.
If applicable, describe any special actions (HQW or ORW) this receiving stream and classification shall
comply with in order to protect the designated waterbodv: NA.
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with 15A
NCAC 2H.0107(c)(2)(B), 40CFR 122.47, and EPA May 2007 Memo: NA.
If applicable, describe any water quality standards variances proposed in accordance with NCGS 143-
215.3(e) and 15A NCAC 2B.0226 for this permit renewal: NA.
7. Technology -Based Effluent Limitations (TBELs)
Municipals (if not applicable, delete and skip to Industrials)
Are concentration limits in the permil at least as stringent as seconday treatment requirements (30 mg/L
BOD-ITSS for Monthly Average, and 45 mg/L for BOW- MS for Weekly Average). YES.
IfNO, provide a justifrcaion for ahernative limitations (e.g., waste stabilization pond). NA.
Are 85% removal requirements for BOD.MS included in tine permit? YES.
IfNO, provide a justification (e.g., waste stabilization pond). NA.
8. Antidegradation Review (New/Expanding Discharge)
The objective of an amidegradation review is to ensure that a new or increased pollutant loading will not
degrade water quality. Permitting actions for new or expanding discharges require an antidegmdation
review in accordance with 15A NCAC 2B.0201. Each applicant for a new/expanding NPDES permit must
document an effort to consider non -discharge alternatives per 15A NCAC 2H.0105(c)(2). In all cases,
existing instrearn water uses and the level of water quality necessary to protect the existing use is maintained
and protected.
If applicable, describe the results of the antldegradation review, including the Engineering Alternatives
Analysis (FAA) and any water quality modeling results: NA.
9. Antibacksliding Review
Page 9 of 14

Sections 402(o)(2) and 303(d)(4) of the CWA and federal regulations at 40 CFR 122.44(I) prohibit
backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a
reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations
may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL
limits, or WQBELs may be less stringent based on updated RPA or dilution).
Are any effluent limitations less stringent than previous permit (YES/NO): No. DWR was informed that
the 7Q10 was revised from 60 cfs (estimate) to 100 cfs (minimum release below Lake Hickory) based on
the relicensing agreement approved by the FERC for the Catawba River lakes, signed in 2006 and amended
in 2018. The updated flows were not used in pennit limit development in order to maintain compliance
with anti -backsliding regulations.
If YES, confirm that antibackslidingprovisions are not violated: NA.
10. Monitoring Requirements
Monitoring frequencies forNPDES permitting are established in accordance with the following regulations
and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500; 2) NPDES
Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance, Reduced
Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best Professional
Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not considered
effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti -backsliding
prohibitions would not be triggered by reductions in monitoring frequencies.
All parameters in the current permit are monitored according to 15A NCAC 2B .0500. The City included
in the renewal application a request for reduced monitoring frequencies for BED, TSS, Fecal Coliform and
Ammonia-N, providing justification and statistical analysis results. Review of effluent data from January
2018 through December 2020 for each parameter found that the data criteria of I ) three-year mean below
50% of the monthly average limit, and 2) no more than 15 (20 for Fecal Coliform) sampling results greater
than 200% of that limit, were met (Table 6).

11. Electronic Reporting Requirements
The US EPA NPDES Electronic Reporting Rule was finalized on December 21, 2015. Effective December
21, 2016, NPDES regulated facilities are required to submit Discharge Monitoring Reports (DMRs)
electronically. Effective December 21. 2020, NPDES regulated facilities will be required to submit
additional NPDES reports electronically. This permit contains the requirements for electronic reporting,
consistent with Federal requirements.

NPDES Implementation of Instream Dissolved Metals Standards - Freshwater Standards
The NC 2007-2015 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. Therefore, metal limits in draft
permits out to public notice after April 6, 2016 must be calculated to protect the new standards - as

General Information on the Reasonable Potential Analysis (RPA)
The RPA process itself did not change as the result of the new metals standards. However, application of
the dissolved and hardness -dependent standards requires additional consideration in order to establish the
numeric standard for each metal of concern of each individual discharge.
The hardness -based standards require some knowledge of the effluent and instream (upstream) hardness
and so must be calculated case -by -case for each discharge.
Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45(c). The
discharge -specific standards must be converted to the equivalent total values for use in the RPA
calculations. We will generally rely on default translator values developed for each metal (more on that
below), but it is also possible to consider case -specific translators developed in accordance with
established methodology.
RPA Permitting Guidance/WQBELs for Hardness -Dependent Metals - Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data, and calculate the allowable effluent concentrations, based on applicable
standards and the critical low -flow values for the receiving stream.
If the maximum predicted value is greater than the maximum allowed value (chronic or acute), the
discharge has reasonable potential to exceed the standard, which warrants a permit limit in most cases. If
monitoring for a particular pollutant indicates that the pollutant is not present (i.e. consistently below
detection level), then the Division may remove the monitoring requirement in the reissued permit.
1. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the
following information:
• Critical low flow of the receiving stream, 7Q10 (the spreadsheet automatically calculates
the 1 Q 10 using the formula 1 Q 10 = 0.843 (s7Q 10, cfs) 0.993
• Effluent hardness and upstream hardness, site -specific data is preferred
• Permitted flow
• Receiving stream classification
2. In order to establish the numeric standard for each hardness -dependent metal of concern and for
each individual discharge, the Permit Writer must first determine what effluent and instream
(upstream) hardness values to use in the equations.
The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for any
hardness data and contacts the Permittee to see if any additional data is available for instream
hardness values, upstream of the discharge.
If no hardness data is available, the permit writer may choose to do an initial evaluation using a
default hardness of 25 mg/L (CaCO3 or (Ca + Mg)). Minimum and maximum limits on the
hardness value used for water quality calculations are 25 mg/L and 400 mg/L, respectively.
If the use of a default hardness value results in a hardness -dependent metal showing reasonable
potential, the permit writer contacts the Permittee and requests 5 site -specific effluent and
upstream hardness samples over a period of one week. The RPA is rerun using the new data.
Page 2 of 4

Permit No. NCO020401
The overall hardness value used in the water quality calculations is calculated as follows:
Combined Hardness (chronic)
_ (Permitted Flow, cfs *Avg. Effluent Hardness, mg/L) + (s70 10, cfs *Avg. Upstream Hardness, mg/L)
(Permitted Flow, cfs + s7Q 10, cfs)
The Combined Hardness for acute is the same but the calculation uses the 1 Q 10 flow.
3. The permit writer converts the numeric standard for each metal of concern to a total recoverable
metal, using the EPA Default Partition Coefficients (DPCs) or site -specific translators, if any
have been developed using federally approved methodology.
EPA default partition coefficients or the "Fraction Dissolved" converts the value for
dissolved metal at laboratory conditions to total recoverable metal at in -stream
ambient conditions. This factor is calculated using the linear partition coefficients
found in The Metals Translator: Guidance for Calculating a Total Recoverable
Permit Limit from a Dissolved Criterion (EPA 823-13-96-007, June 1996) and the
equation:
Cdiss = I
Ctotal 1 + { [Kpo] [ss0+81 [10-6] }
Where:
ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L used,
and
Kpo and a = constants that express the equilibrium relationship between dissolved
and adsorbed forms of metals. A list of constants used for each hardness -dependent
metal can also be found in the RPA program under a sheet labeled DPCs.
4. The numeric standard for each metal of concern is divided by the default partition coefficient (or
site -specific translator) to obtain a Total Recoverable Metal at ambient conditions.
In some cases, where an EPA default partition coefficient translator does not exist (ie. silver), the
dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to
obtain a Total Recoverable Metal at ambient conditions. This method presumes that the metal is
dissolved to the same extent as it was during EPA's criteria development for metals. For more
information on conversion factors see the June, 1996 EPA Translator Guidance Document.
5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration
(permit limits) for each pollutant using the following equation:
Ca = (s7010 + Qw) (Cwgs) — (s7010) (Cb)
Qw
Where: Ca = allowable effluent concentration (itg/L or mg/L)
Cwqs = NC Water Quality Standard or federal criteria (µg/L or mg/L)
Cb = background concentration: assume zero for all toxicants except NH;* (µg/L or mg/L)
Qw = permitted effluent flow (cfs, match s7Q 10)
s7Q 10 = summer low flow used to protect aquatic life from chronic toxicity and human
health through the consumption of water, fish, and shellfish from noncarcinogens (cfs)
* Discussions are on -going with EPA on how best to address background concentrations
Flows other than s7Q 10 may be incorporated as applicable:
1Q10 = used in the equation to protect aquatic life from acute toxicity
Page 3 of 4

Permit No. NC0020401
QA = used in the equation to protect human health through the consumption of water,
fish, and shellfish from carcinogens
30Q2 = used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern.
Data entered must have been taken within four and one-half years prior to the date of the pen -nit
application (40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper
concentration of each pollutant. The Predicted Max concentrations are compared to the Total
allowable concentrations to determine if a permit limit is necessary. if the predicted max exceeds
the acute or chronic Total allowable concentrations, the discharge is considered to show
reasonable potential to violate the water quality standard, and a permit limit (Total allowable
concentration) is included in the permit in accordance with the U.S. EPA Technical Support
Document for Water Quality -Based Toxics Control published in 1991.
7. When appropriate, permit writers develop facility specific compliance schedules in accordance
with the EPA Headquarters Memo dated May 10, 2007 from James Hanlon to Alexis Strauss on
40 CFR 122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and
hexavalent chromium Water Quality Standards. As a cost savings measure, total chromium data
results may be used as a conservative surrogate in cases where there are no analytical results
based on chromium III or VI. In these cases, the projected maximum concentration (95th %) for
total chromium will be compared against water quality standards for chromium Ill and
chromium VI.
9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, are
inserted into all permits with facilities monitoring for hardness -dependent metals to ensure the
accuracy of the permit limits and to build a more robust hardness dataset.
10. Hardness and flow values used in the Reasonable Potential Analysis for this permit included:

Hickory, NC
Dear Sir or Madam,
Enclosed for your review and processing you will find the application package for the renewal of
the City of Hickory's — Northeast Wastewater Treatment Plant NPDES permit. Included in this
cover letter is a brief narrative explaining the biosolids management plan for the Northeast
Wastewater Treatment Plant, as well as a request for this plant to be designated as an
Exceptionally Performing Facility.
The application package includes the following:
• NPDES Form 2A

Part F
• Plant Flow Schematic / Narrative
• Attachment for Part B
• Attachment for Part E
• Attachment for Part F
• Exceptionally Performing Facility (EPF) Justification and Statistical Analyses
The City of Hickory's Northeast Wastewater Treatment Plant processes all of its sludge by
composting. Sludge is removed from the secondary clarifiers and dewatered by a gravity belt
thickener with the addition of polymer. The thickened solids are stored in a thickened sludge tank
before being loaded into tankers and taken to the Hickor/ Regional Compost Facility (Permit #
WQ0004563) in Newton, NC, for further processing into ;lass "A" 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 for use as a
soil amendment.

The City of Hickory is requesting reduced monitoring for this facility per the Exceptionally
Performing Facilities guidance. The Northeast WWTP facility meets all of the requirements for the
reduced monitoring. There were no civil penalties assessed during the past three years; the
permittee nor any of its employees have been convicted of criminal violations under the clean
water act within the last five years; the facility is not under an SOC; and the facility is not on the
EPA's Quarterly Noncompliance Report. Attached you will find the justification and statistical
analysis to support the designation of this plant as an Exceptionally Performing Facility.
Thank you in advance for your review. Should you have any questions regarding this submittal,
please do not hesitate to contact me at [phone] or via email at cbvnumahickorync.gov.

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
If no biomoniloring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to

Process Flow Narrative
Northeast WWTP, NC 0020401
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 flow from the Northern Hickory and Southern Alexander County service areas. The
plant is equipped with two backup generators that are designed to run all plant processes in the
event of power failure.
Flow enters the plant via a 42-inch gravity sewer line into the main influent channel. It is then
split into two parallel channels that each contain an automatic mechanical bar screen. After
flowing through the bar screens the two channels rejoin and flow through a parshall flume. This
provides a measurement of the influent flow before it enters the influent lift station. The influent
lift station pumps wastewater to the headworks structure, which also contains the grit removal
system. Wastewater flows from the grit removal system and enters one of the two oxidation
ditches. The oxidation ditch is a three stage ditch that includes aeration equipment, and is
designed for biological nutrient removal. Wastewater then overflows the effluent weir gates and
enters a splitter box before being routed to the secondary clarifiers. Settled sludge from the
secondary clarifiers enters the RAS/WAS pump station, and is either pumped beck to the
oxidation ditch as return activated sludge, or to the truck loading station as waste activated
sludge. The effluent from the clarifiers flows to the chlorine contact chamber for chlorination,
and at the end of the chamber sulfur dioxide is added prior to post aeration. The effluent then
discharges into the outfall line and is diffused before being released into the receiving stream.

Hi Gary,
The parameter code in the table should be TGP3B for the normal P/F quarterly sampling. It currently has the code
for ChV testing for after quarterly tests fail (THP38).
Everything else looks good, appears no changes to Tax.

Good morning Mr. Bynum,
The 7Q10 value of 60 cfs was an estimate made in the preparation of the 2011 permit. To quote that
permit's fact sheet:
"Note: Since the Federal Energy Regulatory Commission (FERC) license for the Catawba River dams
has not been renewed and updated minimum releases are not final, the estimated s7Q10 flow of 60 cfs is
based on the historical minimum release of 40 cfs from the dam below Lake Rhodhiss and estimated
flows of —20 cfs at the mouths of Gunpowder Creek and Little River."
So yes, if this is inaccurate or outdated, I would consider the more recent information you have now
provided. Thank you for bringing it up.
If you have any other questions of comments regarding this permit draft, the Division would consider
them as well.
Thanks and stay safe,
Gary Perlmutter

Mail - Perlmutter, Gary - Outlook
After review of the Hickory NE W WTP draft permit we have a few concerns regarding the 7Q10 flow number used
in the analysis. Do you know what information was used to derive the flow of 60 cfs?
We understand that the 7Q10 is the lowest 7-day average flow that occurs (on average) once every 10 years.
However, since Lake Hickory is a run of the river impoundment controlled by flow from the Oxford Dam we feel
like that should be taken into account.
In the Comprehensive Relicensing Agreement for the Catawba-Wateree Hydro Project (FERC Project No. 2232) the
minimum continuous flow established for the Oxford Development is 150 cfs. From our understanding the only
time that flows may fall below that number is when Low Inflow Protocols are being followed. The critical flow
established by the Low Inflow Protocol for the Oxford Regulated Reach below the Oxford Development is 100 cfs.
Catawba-Wateree Relicensing - Duke Energy_(duke-energy.com)
Based on the requirements that Duke Energy must follow, we feel like the 7Q10 number in our permit should be
updated.
Let me know if you have any questions.

Permit NCO020401
Northeast WWTP
Catawba County
Grade IV Biological WPCS
SIC Code 4952
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains. There are several changes from the existing permit, including the following:
Based on the reasonable potential analysis (RPA) showing no reasonable potential to
violate state water quality standards, the monitoring requirements for Total Cadmium and Total
Silver have been removed from the permit [See A. (I.)].
Based on NPDES guidance regarding the reduction of monitoring frequencies in NPDES
permits for exceptionally performing facilities, monitoring requirements for BODt, NH.3-N,
Total Suspended Solids and Fecal Coliform have been reduced to twice per week [See A.
U A.
. The City of Hickory reported Bis (2-ethylhexyl) phthalate at less than detection of all
samples tested, among which one was at detection level < 50.0 µg/L and another at < 25.0
µg/L in the DMR results). The City's allowable discharge concentration for Bis (2-ethylhexyl)
phthalate is 8.1 µg/L. DWR's laboratory identifies the target Practical Quantification Limit
(PQLs) for Bis (2-ethylhexyl) phthalate as 10.0 µg/L. 15A NCAC 2B .0505 (e) (4) requires
that all test procedures must produce detection and reporting levels that are below the permit
discharge requirements and all data generated must be reported to the approved detection level
or lower reporting level of the procedure. If no approved methods are capable of achieving a
detection level below the permit discharge requirement (or allowable discharge concentration)
the method with the lowest detection level must be used. The City should use sufficiently
sensitive test methods for all pollutants, including when performing Effluent Pollutant Scans.
Quarterly monitoring for Bis (2-ethylhexyl) phthalate has been maintained.
Instream monitoring parameters have been removed from the Effluent sheet [A. (I.)] and
placed as a separate Special Condition [See A. (2.)].
• Some of the wording has changed in Special Condition A. (3.). Chronic Toxicity Permit

A. (3.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) [15A NCAC 02B .02001
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 Ceriodaplmia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent versions
or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised December 2010) or
subsequent versions. The tests will be perforated 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 11 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 electronically using the
Division's eDMR system for the months in which tests were performed, using the parameter code TGP3B for the
pass/fail results and THP311 for the Chronic Value. Additionally, DWR Fonm AT-3 (original) is to be sent to the

Monitoring Reports
I. Reportine Requirements ISunersedes Section D (2) and Section E. (5) (a)I
The Permittee shall report discharge monitoring data electronically using the 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. The eDMR system may be
accessed at: https:Hdeg.nc.gov/about/divisions/water-resources/edmr.
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 maybe submitted on paper DMR forms (MR I, 1.1, 2.3) or alternative
forms approved by the Director. Duplicate signed copies shall be submitted to the following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Centel -
Raleigh, North Carolina 27699-1617
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 new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2025, 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.

Perm it NC0020401
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(I)(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)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at:
httt s•//www federalrepister gov/documents/2015/10/22/2015-24954/national-pollutant-discharge-
elimination-system-nodes-electronic-reporting-rule.
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The Permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data
and reports shall be submitted electronically to the Division unless the permittee re -applies for and
is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
http://detA.nc.gov/about/divisions/water-resources/ediiir.
