Subject: Draft NPDES Permit Renewal
Permit NC0023965
James A. Loughlin(Northside)WWTP
New Hanover County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Waldroup:
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:
• As the receiving stream is PNA waters and more restrictive limitations for BODs, TSS
and NH3 as N are required under 15A NCAC 02B .0224 than the historical limits identified
for when the facility was rated for 8.0 MGD, Special Condition A.(7.) Historical Permit
Limits has been removed from the permit.
• As the federal Anti-backsliding rule exceptions are outlined in Section 402(o)(2) of the
Clean Water Act, Special Condition A.(8.)Anti-Backsliding has been removed from the
permit.
• As the facility has demonstrated consistent capability of achieving compliance with TSS
limits required under 15A NCAC 02B .0224 for High Quality Waters, the TSS limits have
been revised to reflect the appropriate requirement.
• Based on review of instream data and discussion with the Basin Planning Branch,
instream monitoring for ammonia, TKN,NO2+NO3, TP and pH has been added to the permit
[See A.(1.)].
• Total Residual Chlorine (TRC) limits and monitoring requirement have not been in the
permit, as the facility uses UV for disinfection. However, in the event of an emergency where
chlorination is required as a backup or temporary means of disinfection at the facility, a TRC
limit and monitoring requirement have been added to the permit. Please note that TRC
monitoring is only required when chlorine is used at the plant.
• To assess contribution of PFAS from the Northside WWTP to the Cape Fear River Basin
and assess levels of PFAS compounds in the facility influent and effluent, Special Condition
A.(5.) has been added to the permit. Please review each paragraph carefully.

• Some of the wording has changed in Special Condition A.(2.), Chronic Toxicity Permit
Limit, please review each paragraph carefully.
• Special Condition A.(3.)has been modified to include the specific three years in which the
Effluent Pollutant Scan shall be performed (2025, 2026, and 2027). 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.
• 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.
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

A.(2.) CHRONIC TOXICITY PERMIT LIMIT(QUARTERLY)
[15A NCAC 02B .0200] [15A NCAC 02B .0500 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 4.8%.
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
February,May,August,and November.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 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,ATForms.ATB@deq.nc.gov.
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 fmal 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.
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.(6.) STIPULATION OF PARALLEL FORCE MAINS
[G.S. 143-215.1 (B)]
By Authorization to Construct(A to C)for expansion to 16 MGD,the Division approved a new effluent
force main and outfall(Outfall 002 with diffuser)approximately parallel to the existing effluent force
main.The Permittee shall sample final treated effluent upstream of any flow split to effluent pump
stations or discharge force mains.The Division acknowledges separate outfalls,however due to their
proximity and the single sampling regime conducted prior to splitting,the Division shall designate and
regulate this discharge as a single outfall(Outfall 001).The Division may reopen this permit to designate
separate outfalls.
A.(7.) FILTER BYPASS PROHIBITION IN A PRIMARY NURSERY AREA(PNA)
[15A NCAC 02B .0220]
This outfall discharges to a segment of the Cape Fear River classified as a primary nursery area(PNA)
[15A NCAC 03R.0103(19)(a)].Therefore,at no time shall the effluent bypass the tertiary filters.
However,the number of filters which are on-line at any given time may be adjusted for routine

A.(8.) ELECTRONIC REPORTING- DISCHARGE MONITORING REPORTS
[G.S. 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 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
Page 9 of 14
Permit NC0023965
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 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.
Monitoring results obtained during the previous month(s)shall be summarized for each month and
reported via the eDMR system no later than the last calendar day of the month following
g the
completed reporting period. 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; and
• 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)].
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.federalregister.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 facilitywould be required
under this permit to begin submitting monitoring data and reports. The duration of a temporary
Page 10 of 14
Permit NC0023965
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://deq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B.(11.) (b)and Supersedes Section B. (11.)(d)1
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:
http://deq.nc.gov/about/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall make
the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION
WILL BE ACCEPTED:
"1 certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the information,
the information submitted is, to the best of my knowledge and belief true, accurate, and complete. I
am aware that there are significant penalties for submitting false information, including the
possibility of Ernes and imprisonment for knowing violations."
5. Records Retention [Supplements Section D. (6.)1
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions.
These records or copies shall be maintained for a period of at least 3 years from the date of the report.
