Subject: Draft NPDES Permit Renewal
Permit NC0026611
Morehead City WWTP
Carteret County
Facility Class IV
SIC Code 4952
Dear Mr. Whitlow:
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 facility detected no di-n-butyl phthalate in its discharge monitoring reports and used
a method of analysis more sensitive than the target method identified by the DWR Water
Sciences Laboratory, the monitoring requirement for di-n-butyl phthalate has been removed
from the permit[See A.(1)].
• Based on the reasonable potential analysis (RPA) showing reasonable potential to violate
state water quality standards,total copper,total nickel and total zinc limits have been added to
the permit and the quarterly monitoring requirement has been changed to monthly
monitoring[See A.(1)].
• To provide an opportunity for the Town to develop a plan to assess sources of total copper,
total nickel and total zinc in order to come in compliance with the limits in Section A.(1),a 5-
year schedule of compliance has been added to the permit [See Special Condition A. (5)
Schedule of Compliance for Total Copper,Total Nickel and Total Zinc Limitations].
• Based on Mercury TMDL evaluation showing all reported mercury values at levels< 1
ng/L, Special Condition A.(7)Mercury Minimization Plan has been removed from the
permit.
• The Town of Morehead City reported Total Arsenic,Total Cadmium,Total Lead,and
Total Silver at less than detection,with detection levels< 10.0 µg/L for each parameter in
the Effluent Pollutant Scans. The Town's allowable discharge concentrations are 5.0 µg/L,
4.45 µg/L,4.25 µg/L,and 0.05 µg/L for Total Arsenic,Total Cadmium,Total Lead,and
Total Silver,respectively.DWR's laboratory identifies the target Practical Quantification
Limits(PQLs) for Total Arsenic,Total Cadmium,Total Lead,and Total Silver as 2.0 µg/L,
0.5 µg/L,2.0 µg/L, and 1.0 µg/L,respectively. 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 Town should use sufficiently sensitive test methods for all pollutants,including when
performing Effluent Pollutant Scans.
• Some of the wording has changed in Special Condition A. (3), Chronic Toxicity Permit
Limit,please review each paragraph carefully.
• Special Condition A.(6)has been modified to include the specific three years in which the
Effluent Pollutant Scan shall be performed (2020, 2021, and2022). In addition, at the end of
the Special Condition, 2"d 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. (6)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A. (1)].
• Regulatory citations have been added to the permit.
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/2BZ4xxx and can be viewed online or downloaded as a PDF file.
Concurrent with this notification the Division is publishing a notice in a newspaper having
circulation in the general Carteret County area, soliciting public comments on this draft permit.
Please provide any written comments you may have to the following: NCDEQ/DWR,NPDES

A. (3) ACUTE TOXICITY PASS/FAIL LIMIT(QRTRLY)
[15A NCAC 02B .0200 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 February, May, August, and November.
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.
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 on the Effluent Discharge
Monitoring Form (MR-1) 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:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,NC 27699-1621
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.
Page 5 of 12
Permit NC0026611
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests,as well as all dose/response data.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 facilityduringa month in which g 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. (4) CALCULATION OF TN AND TP LOADS
[G.S. 143-215.1(b)]
a. The permittee shall calculate monthly and annual TN Load and TP Load as follows:
i. Monthly TN(or TP)Load(lbs/month)=TN(or TP)(mg/L)x TMF x 8.34
where:
TN = the average Total Nitrogen(or Total Phosphorus)
(or TP) concentration(mg/L)of the composite samples collected
during the month
TMF = the Total Monthly Flow of wastewater discharged during
the month(MG/mo)
8.34 = conversion factor, from(mg/L x MG)to pounds
ii. Annual TN(or TP) Load(lbs/year)=Sum of the Monthly TN(or TP)Loads
for the calendar months January through December.
b. The permittee shall report monthly TN Load (QM600) and TP Load (QM665) results
(lbs/month) on the last day of the appropriate discharge monitoring report for each
calendar month(January through December). Annual TN Load (QY600) and TP Load
(QY665) results (lbs/year) shall be reported on December 31 st discharge monitoring
report for that calendar year.

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal
facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to
additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5). The US EPA
requires four(4)toxicity tests for a test organism other than the test species currently required in this permit.
The multiple species tests should be conducted either quarterly for a 12-month period prior to submittal of
the permit renewal application,or four tests performed at least annually in the four and one half year period
prior to the application. These tests shall be performed for acute or chronic toxicity,whichever is specified
in this permit. The multiple species toxicity test results shall be filed with the Aquatic Toxicology Branch at
the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the
additional toxicity tests and reporting requirements. Results should also be summarized in Part E(Toxicity
Testing Data) of EPA Municipal Application Form 2A,when submitting the permit renewal application
to the NPDES Permitting Unit.
A. (7)NOTIFICATION OF RELEASE
[G.S. 143-215.1(b)]
The permittee shall notify the Shellfish Sanitation and Recreational Water Quality Section of any release
of partially treated wastewater or untreated wastewater into Calico Creek. The notification shall be made
within three hours of the spill to the North Carolina Division of Marine Fisheries communication center at
(252) 726-7021. This notification does not relieve the permittee of other spill notifications procedures as
required by other agencies.
A. (8)TEMPORARY MEANS OF DISINFECTION
[G.S. 143-215.1(b)]
In the event that the wastewater treatment plant's ultraviolet (UV) disinfection system should fail,
underperform, or otherwise be removed from effective service, the permittee or his agent should
immediately inform the Surface Water Protection Section staff of the Wilmington Regional Office of this
development and discuss temporary,alternate means for disinfection of the effluent.
If chlorine compounds are used as temporary means of disinfection, the total residual chlorine (TRC)
concentration of the effluent must be monitored on a daily basis while this method of disinfection is in use,
and values must be reported on the discharge monitoring report. TRC in the effluent shall not exceed the
recognized minimum measurable TRC of 50 µg/L,all values shall be reported even when less than 50 µg/L;
therefore, dechlorination methods may also be necessary to ensure protection of water quality in the
receiving stream.
Use of a disinfection system other than the permitted UV system during circumstances not deemed as
emergency and/or temporary(replacement of lamps,lamp cleaning or maintenance,etc.)will be considered
a violation of the terms of this permit.

A. (9)ELECTRONIC REPORTING OF 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)I
The pennittee shall report discharge monitoring data electronically using the NC D W R'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 intemet. Until such time that the state's eDMR
application is compliant with EPA's Cross-Media Electronic Reporting Regulation(CROMERR),
pennittees will be required to submit all discharge monitoring data to the state electronically using
eDMR and will be required to complete the eDMR submission by printing,signing,and submitting one
signed original and a copy of the computer printed eDMR to the following address:
NC DEQ/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
If a pennittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband access,
then a temporary waiver from the NPDES electronic reporting requirements may be granted and
discharge monitoring data may be submitted on paper DMR forms(MR 1, 1.1,2,3)or alternative forms
approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See
"How to Request a Waiver from Electronic Reporting"section below.
Regardless of the submission method,the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility,on the last day of the month following the
commencement of discharge.
Starting on December 21,2020,the permittee must electronically report the following compliance
monitoring data and reports,when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports;and
• Clean Water Act(CWA)Section 316(b)Annual Reports.
The permittee may seek an electronic reporting waiver from the Division(see"How to Request a Waiver
from Electronic Reporting"section below).
Page 10 of 12
Permit NC0026611
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 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.
