Subject: Draft NPDES Permit Renewal
Permit NC0025348
New Bern WWTP
Craven 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 copper and cyanide have
been removed from the permit [See A. (2.)].
• Based on the RPA predicting a maximum effluent zinc concentration that is greater than
half of allowable discharge concentration based on state water quality standards, quarterly
monitoring for zinc has been added to the permit [See A. (2.)].
• Based on RPA showing a reasonable potential to violate state quality standards from a
limited dataset (n < 8 samples with one exceedence), quarterly monitoring for
Bromodichloromethane has been added to the permit [See A. (2.)].
• Based on Mercury TMDL evaluation showing detection of mercury at levels > 1 ng/L,
Special Condition A. (12.) Mercury Minimization Plan has been reworded toward its
maintenance
• Total Silver limits of 0.10 µg/L monthly average and 2.2 µg/L daily maximum were added
to the permit with monthly monitoring. A footnote has been added to the Effluent Sheet for
Silver to test and report to the lower reporting level of the procedure [See A. (2.)]. DWR's
laboratory identifies the target Practical Quantification Limits (PQLs) for Total Silver as
1.0 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.
• Based on interpretation of instream conductivity data showing an increase downstream,
daily effluent Conductivity monitoring has been added to the permit [See A. (2.)].
• Based on Best Professional Judgement (BPJ) in consideration of the submitted
groundwater modeling results and the porosity of the bedrock below East Lake bordering the
Neuse River, a 50% TN credit is assigned to wastewater diversion to the East Lake High -Rate
Infiltration Disposal System that will expire upon the next permit cycle [See A. (5.)].
• For consistency with other instream monitoring parameters, vertical instream monitoring
for pH has been changed from top and bottom to every 1-foot interval throughout the water
column [See A. (6.)].
• Some of the wording has changed in Special Condition A. (10.), Acute Toxicity Permit
Limit, please review each paragraph carefully.
• Special Condition A. (12.) has been modified to include the specific three years in which
the Effluent Pollutant Scan shall be performed (2024, 2025, and 2026). In addition, at the end
of the Special Condition, 2na species Toxicity Testing Requirements for municipal permit
renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added.
• 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 Special Condition A. (13.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[See A. (1.) through A. (5.)] and Instream Monitoring Requirements [See A. (6.)].
• Regulatory citations have been added to the permit.
• The facility map has been updated to show instream monitoring locations.
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 cand can be viewed online or downloaded as a PDF file.

Permit NC0025348
A. (7.) CALCULATION OF TOTAL NITROGEN LOADS — NEUSE ESTUARY [NCGS 143-215.1(b)]
a. The Permittee shall calculate monthly and annual TN Loads as follows:
(i.) Monthly TN Load (lb/mo) = TN x TMF x 8.34
where: TN = the average Total Nitrogen concentration (mg/L) of the composite samples
collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the month
(MG/month)
8.34 = conversion factor, from (mg/L x MG) to pounds
(ii.) Annual TN Load (lb/yr) = Sum of the 12 Monthly TN Loads for the calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and lb/mo) in the discharge monitoring report
for that month and shall report each year's results (lb/yr) in the December report for that year.
A. (8.) ANNUAL LIMITS FOR TOTAL NITROGEN — NEUSE ESTUARY [NCGS 143-215.1(b)]
a. Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse River basin apply
on a calendar year basis.
b. For any given calendar year, the Permittee shall be in compliance with the annual TN Load limit in this
Permit if:
(i.) the Permittee's annual TN discharge is less than or equal to its TN Load limit, or
(ii.) the Permittee is a co-permittee member of a compliance association.
c. If the Permittee is not a co-permittee member of a compliance association and the Permittee's cumulative
annual TN discharge exceeds the effective TN Load limit in this permit at any point during the calendar
year, the Permittee is in violation of its TN Load limit, and each day of a continuing violation shall constitute
a separate violation.
d. The TN Load limit in this Permit (if any) may be modified as the result of allowable changes in the
Permittee's TN allocation.
(i.) Allowable changes include those resulting from purchase of TN allocation from the Wetlands
Restoration Fund; purchase, sale, trade, or lease of allocation between the Permittee and other
dischargers; regionalization; and other transactions approved by the Division.
(ii.) The Permittee may request a modification of the TN Load limit in this Permit to reflect allowable
changes in its TN allocation. Upon receipt of timely and proper application, the Division will modify
the permit as appropriate and in accordance with state and federal program requirements.
(iii.) Changes in TN limits become effective on January 1 of the year following permit modification. The
Division must receive application no later than August 31 for changes proposed for the following
calendar year.

A. (10.) SALTWATER -ACUTE TOXICITY PASS/FAIL LIMIT (QUARTERLY)
[15A NCAC 02B .0200] [15A NCAC 02B .0500 et seq]
The Permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North Carolina
Procedure Document entitled "Pass/Fail Methodology for Determining Acute Toxicity In A Single Effluent
Concentration" (Revised December 2010, or subsequent versions). The monitoring shall be performed as a Mysid
Shrimp (Mysidopsis bahia) 24-hour static test. The effluent concentration at which there may be at no time
significant acute mortality is 90% (defined as treatment two in the procedure document). The tests will be
performed during the months of March, June, September, and December. 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 (i.e., when including WTP discharge and not diverted to East
Lake) and shall be performed at the NPDES permitted final effluent discharge below all treatment processes.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
All toxicity testing results required as part of this permit condition will be entered electronically using the
Division's eDMR system for the month in which it was performed, using the parameter code TGE3E.
Additionally, DWR Form AT-2 (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, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this monthly test
requirement will revert to quarterly in the months specified above. 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 either these monitoring requirements 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 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. (13.) ELECTRONIC REPORTING — 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)]
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 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:
North Carolina Division of Water Resources
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.
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.
Page 14 of 17

DocuSign Envelope ID: 4FE2A421-DE4B-413C-A4AE-793BF2B0D4D8
Permit NC0025348
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 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)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:
"I 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 fines and imprisonment for knowing violations."
