Subject: Final NPDES Permit Renewal
Permit NC0047597
South Durham WRF
Durham County
Grade IV Biological WPCS
SIC Code 4952
Dear Ms. Westbrook:
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).
No changes were made to the second draft permit sent to you on October 19, 2022, as no comments
were received from any party.
The final permit maintains the significant changes made to the first draft permit sent to you on
September 9, 2022:
• Corrections were made to the system component list on the Supplement to Cover Sheet.
• Effluent monitoring for BOD, TSS, Ammonia and Fecal Coliform were reduced from daily to
2/week based on the facility meeting criteria for Reduction of Monitoring Frequencies in NPDES
Permits for Exceptionally Performing Facilities (Division guidance document, 2012) [See A. (1.)].
• Instream monitoring for Fecal Coliform was removed based on review of the data (effluent values
are much lower than instream values) and that the receiving stream is neither Class B nor impaired
for Fecal Coliform [See A. (2.)].
• Twelve-month rolling average Total Nitrogen and Total Phosphorus loads were removed from the
permit as mass nutrient limits are established as calendar -year limits per the Jordan Water Supply
Nutrient Strategy (15A NCAC 2B .0270) [See A. (7.)].
• Clarifying language was added to the Nutrient Optimization special condition so that if
optimization steps are not deemed necessary to meet the limits at the design flow, they will not be
required [See A. (8.)(b.) and (c.)].
• WER-related deadlines in the Schedule of Compliance for Copper, Silver and Zinc were extended
to allow more time for the City to prepare and implement a WER study [See A. (11.)].

• For clarification purposes, the definition of Daily Monitoring is Monday through Friday except
holidays (see Permit Part II, Standard Conditions, Section A. Definitions, under "Daily Sampling").
No additional changes are necessary.
This final permit maintains the following significant changes identified in the letter sent on
September 9, 2022:
• The topographic map was updated to show instream monitoring locations.
• The system component list was updated (see Supplement to Cover Sheet)
• Regulatory citations have been added to the permit.
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements sheet
[See A. (1.)], Instream Monitoring Requirements [See A. (2.)] and the Effluent Pollutant Scan [See
A. (4.)] sections.
• Based on the implementation of nutrient (TN and TP) load limits, their effective dates have been
removed from the permit [See A. (1.)].
• The Division is implementing dissolved metals standards in all permits, per the 2016 revisions to
State water quality standards. As such, 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. However, because the receiving stream 7Q10
is effectively 0 at 0.15 cfs, instream hardness sampling, upstream of the discharge, is not needed.
Effluent hardness has been added to the permit at a monitoring frequency of quarterly [See A. (1.)].
• Based on the reasonable potential analysis (RPA) showing reasonable potential to violate state
water quality standards, Total Copper, Total Silver, and Total Zinc limits have been added to the
permit and the quarterly monitoring requirements have been changed to monthly monitoring [See
A. (1.)].
• Based on the RPA predicting a maximum effluent Nitrate -Nitrogen (NO3-N) and Total Dissolved
Solids (TDS) concentration that is greater than the allowable discharge concentration based on state
water quality standards, quarterly monitoring for NO3-N and TDS have been added to the permit
[See A. (1)].
• To provide an opportunity for the Town to develop a plan to assess sources of total copper, total
silver and total zinc in order to come in compliance with the limits in Section A. (1.), a schedule of
compliance with a WER option has been added to the permit [See Special Condition A. (10.)
Schedule of Compliance for Total Copper, Total Silver and Total Zinc Limitations].
• Based on limited dataset from the investigative sampling in 2019 indicating detectable levels in the
influent, monthly effluent monitoring for 1,4-Dioxane has been added to the permit [See A. (1.)
and A. (2.)].
• Based on Mercury TMDL evaluation showing no individual results exceeded the TBEL of 47 ng/L
and no annual average exceeded the WQBEL of 12.0 ng/L, Mercury limits have been removed
from the permit.
• Based on Mercury TMDL evaluation showing detections > 1 ng/L and the design flow is > 2 MGD,
a Mercury Minimization Plan (MMP) special condition has been added to the permit. [See A. (9.)].
• To provide nutrient data year-round, instream monitoring for TP, PO4, TKN, NO3+NO2 has
changed from 1/week, June 1—September 30, to 1/month year-round. [See A. (2.)].
• Wording in Special Conditions A. (3.) Chronic Toxicity Permit Limit, and A. (4.) Effluent Pollutant
Scan have been updated to allow for electronic submittal and to clarify second species toxicity
testing. Please review each special condition carefully.
• Special Condition A. (4.) — Effluent Pollutant Scan has been modified to include the specific three
years in which the Effluent Pollutant Scans shall be performed (2024, 2025, and 2026). In addition,
at the end of the Special Condition, 2nd species Toxicity Testing Requirements for municipal permit
renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added.
• Monthly monitoring for 1,4-Dioxane was added to the permit.

• A permit reopener special condition has been added to modify 1,4-Dioxane monitoring, treatment
and/or compliance [See A. (11.)].
• A special condition to monitor effluent PFAS chemicals quarterly has been added to the permit, to
be effective six (6) months after EPA has a final wastewater method in 40 CFR 136 method
published in the Federal Register [See A. (12.)].
• 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. (13.)].
Pretreatment updates in response to NPDES permit renewal:
• On June 5, 2023, 180 days after the effective date of this NPDES permit renewal, the City is
required to submit to the Division a written technical evaluation of the need to revise local limits
(i.e., an updated IWS/HWA-AT/L-STMP, or documentation of why is not needed). This action
may include revising, updating, or adding to the list of SIUs regardless of timeframe.
o Submit the updated Long -Term Monitoring Plan (LTMP)
• If there are new industries within the service area, submit an updated Industrial
Waste Survey (IWS)
• Review pollutants of concern (POCs) and update the LTMP to reflect pollutants in
industrial user permits (IUPs) and sludge management permit.
o As part of the local limits assessment, please submit the updated Headworks Analysis
(HWA).
The NPDES standard conditions (Parts II, III, and IV) that are a part of the permit are not included in this
draft document (cover, map, and Part I). The conditions are the same as in your current 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.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable
to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following
receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of
the North Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail
Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be
final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect the legal requirements
to obtain other permits which may be required by the Division of Water Resources or any other Federal,
State, or Local governmental regulations.

A.(3.) FRESHWATER CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
[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 90%.
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 II 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 Chronic Value
(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 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:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Or, results can be sent to the email, [e-mail] .
Completed Aquatic Toxicity Test Forms shall be filed with the Water 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 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 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.

Permit NC0047597
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.
If the Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Form
submitted.
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.(14.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[NCGS 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports.
The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this permit
(Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
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 monthly DMRs electronically using the internet. The eDMR system may be accessed at:
https://deq.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 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 following address:
NC 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 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.

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)].
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:
http s://www. federalregi ster. gov/documents/2015/ 10/22/2015-24954/national-pollutant-discharge-elimination-
system-npdes-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 five (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://deq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)l
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section
B. (11.)(a) or by a duly authorized representative of that person as described in Part II, Section B. (11.)(b). A
person, and not a position, must be delegated signatory authority for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user account and
login credentials to access the eDMR system. For more information on North Carolina's eDMR system,
registering for eDMR and obtaining an eDMR user account, please visit the following web page:
