Permit NC0079057
Manteo WWTP
Dare County
Grade III Biological WPCS
SIC Code 4952
Dear Mr. Skinner:
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 NPDES guidance regarding the reduction of monitoring frequencies in NPDES
permits for exceptionally performing facilities, monitoring requirements for BOD5,NH3-
N, Total Suspended Solids and Enterococci have been reduced to twice per week [See
A.(1) and A.(2)].
• Based on instream sampling review, the summer instream monitoring frequency has been
reduced and modified to be consistent with the winter instream monitoring frequency.
• Based on the reasonable potential analysis (RPA) results, quarterly monitoring for nickel
has been added to the permit [See A.(1) and A.(2)].
• Based on the reasonable potential analysis (RPA) results, total copper limits and monthly
monitoring for total copper have been added to the permit [See A.(1) and A.(2)].
• To provide the Permittee time to assess causes of excursions above the allowable
discharge levels for Total Copper,Special Condition A. (4) Schedule of Compliance for
Total Copper Limitations has been added to the permit.
• Based on Wasteload Allocation (WLA) review, summer and winter ammonia limits
have been changed for the 1.0 MGD flow tire [See A.(2)].
• The Town of Manteo reported Total Arsenic, Total Cadmium, Total Lead and Total
Silver at less than detection, each with a detection level < 10 µg/L in the Effluent
Pollutant Scans. The Town's allowable discharge concentrations are 10.0 µg/L, 8.90
µg/L, 8.50 µg/L and 0.10 µg/L for Total Arsenic, Total Cadmium, Total Lead, and Total
Silver, respectively, based on the water quality standard and stream dilution. DWR's
laboratory identifies the target Practical Quantification Limit(PQL) for for Total Arsenic,
Total Cadmium, Total Lead and Total Silver as 2 µg/L, 0.5 µg/L, 2 µg/L and 1 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 shall be used. The Town of Manteo shall test for
Total Arsenic, Total Cadmium, Total Lead and Total Silver down to the target PQL,
including when performing Effluent Pollutant Scans. While no monitoring requirement
has been added to the permit for Total Arsenic, Total Cadmium, Total Lead or Total
Silver at this time, the Division can modify the permit and add a limit or add limits during
the next renewal if this regulation is not satisfied.
• The Permittee shall use EPA Method 1631E when sampling for Total Mercury,
including when performing Effluent Pollutant Scans.
• Some of the wording has changed in Special Condition A. (3), Acute Toxicity Permit
Limit, please review each paragraph carefully.
• Special Condition A. (5) has been modified to account for the Permittee potentially
expanding later within a permit cycle. 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.
• 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) and A. (2)].
• Regulatory citations have been added to the permit.
The NPDES Standard Conditions (Parts II, III, and IV)are not included with this draft. The latest
version is available at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF
file.

A. (3) ACUTE TOXICITY PERMIT LIMIT (Quarterly)
[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 Fathead Minnow (Pimephales promelas) 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. 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.
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 TGE6C. 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, North Carolina 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.
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 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.

Permit NC0079057
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) SCHEDULE OF COMPLIANCE FOR TOTAL COPPER LIMITATIONS
[NCGS 143-215.1 (b)]
1. Within one (1) year from the effective date of the permit, the Permittee shall submit

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. (6) 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)]
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. Until
such time that the state's eDMR application is compliant with EPA's Cross-Media Electronic
Page 10 of 12

Permit NC0079057
Reporting Regulation (CROMERR), permittees 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 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 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).
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

Permit NC0079057
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://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."
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. This period may be extended by request of the Director at any time[40 CFR
122.41].
