Subject: Draft NPDES Permit Renewal
Permit NCO021865
Chadbourn WWTP
Columbus County
Grade III 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, but demonstrating a predicted maximum
concentration that is greater than 50% of the allowable discharge concentration, total
copper limits have been removed from to the permit and monthly monitoring has been
reduced to a quarterly frequency [See A.(1.)].
• Based on the reasonable potential analysis (RPA) demonstrating that reasonable potential
to violate state water quality standards exists using a limited data set with fewer than two
samples exceeding allowable discharge concentrations, quarterly monitoring for total
nickel has been added to the permit [See A.(1.)].
• Per the results of instream waste concentration (IWC)-based calculations for ammonia
nitrogen, ammonia nitrogen limits have been revised [See A.(1.)].
• Per 15A NCAC 02B .0508, monitoring requirements for total nitrogen, total phosphorous,
TKN and NO3-N + NO2-N have been changed from quarterly to monthly [See A.(1.)].
• The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the
NC Environmental Management Committee (EMC) on November 13, 2014. The US EPA
subsequently approved the WQS revisions on April 6, 2016 with some exceptions. The NC
Division of Water Resources NPDES Permitting Unit is required to implement the new
dissolved metal standards in all permits public noticed after April 6, 2016. The new
standards for most metals include acute standards. Further, the freshwater standards for
several metals are expressed as the dissolved form of the metals, and seven metals have
hardness -dependent equations. As a result, 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. Effluent
hardness and instream hardness sampling, upstream of the discharge, have been added to
the permit at a monitoring frequency of quarterly [See A. (1.)].

• The Town reported Total Silver and Total Selenium at less than detection, with a detection
level < 5 µg/L and < 10 µg/L, respectively, in their effluent pollutant scans. The Town's
chronic allowable discharge concentration is 0.066 µg/L for Total Silver and 5.5 µg/L for
Total Selenium. DWR's laboratory identifies the target Practical Quantification Limits
(PQL) as 1.0 µg/L for both Total Silver and Total Selenium. 15A NCAC 213 .0505 (e) (4)
requires that all test procedures must produce detection and reporting levels that are below
the permit discharge requirements. If no approved methods are capable of achieving a
detection level below the permit discharge requirement (or allowable concentration) the
method with the lowest detection level must be used. The Town shall test for Total Silver
and Total Selenium down to a PQL below the allowable discharge concentration. While no
monitoring requirement has been added to the permit for Total Silver or Total Selenium at
this time, the Division would add limits during the next renewal if this regulation is not
satisfied.
• 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 (2022, 2023, and 2024). In addition, at the end
of the Special Condition, 2nd species Toxicity Testing Requirements for municipal permit
renewals per Federal Regulations [40 CFR 122.210)(5)] have been added.
• A notation was made concerning the Electronic Reporting Rule — Phase 2 Extension. EPA
is proposing to extend the Phase 2 deadline from December 21, 2020, to December 21,
2025. The current compliance date will be extended if the implementation date is extended
as a final regulation change in the federal register.
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A.(L)].
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
h Vs://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 Columbus County area, soliciting public comments on this draft permit.
Please provide any written comments you may have to the following: NCDEQ/DWR, NPDES
Permitting Branch, 1617 Mail Service Center, Raleigh, NC 27699-1617 no later than 30 days
after receipt of this draft permit.
Following the 30-day public comment period, the Division will review all pertinent comments
and take appropriate action prior to issuing a final permit. If you have questions concerning this
draft permit, please contact me at (919) 707-3609 or by email at nick.coco@ncdenr.gov.

Footnotes (continued
4. 2/ Week sampling must occur on any two non-consecutive days during the calendar week.
5. The Division shall consider all effluent total residual chlorine values reported below 50 ug/1 to be in compliance
with the permit. However, the permittee shall continue to record and submit all values reported by a North
Carolina certified laboratory (including field certified), even if these values fall below 50 ug/l.
6. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent metals
(cadmium, copper, lead, nickel, silver, and zinc).
7. Chronic Toxicity (Ceriodaphnia) P/F @ 90%, March, June, September, December; See Special Condition A.(2.).
8. The Permittee shall perform three Effluent Pollutant Scans during the term of this permit [see A.(1)].
9. The Permittee shall sample instream hardness, upstream of the facility's discharge. The sample shall be
representative of the hardness in the receiving stream. If the Permittee is a member of the Monitoring Coalition
Program, sampling for instream hardness may be waived as long as the Monitoring Coalition agrees to sample
hardness at the nearest upstream location, at a minimum frequency of quarterly, and the Permittee has obtained
approval from DWR - NPDES Permitting Unit that the upstream station being monitored by the Coalition is
representative of the receiving stream for this discharge. The Permittee is responsible for submitting instream
hardness test results with its permit renewal application package. If Coalition membership is cancelled or the
Coalition terminates instream hardness sampling at the approved station, the Permittee will immediately notify the
Division and resume sampling for instream hardness, upstream of its discharge.
b. There shall be no discharge of floating solids or visible foam in other than trace amounts.
A.(2.) 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, uag rterl monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or "North Carolina Phase I1 Chronic Whole Effluent Toxicity Test Procedure"
(Revised- December 2010) or subsequent versions. 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 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:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1623
Or, results can be sent to the email, ATForms.ATB@ncdenr
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
Page 4of11
Permit NC0021865
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.
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.(3.) EFFLUENT POLLUTANT SCAN
[G.S.143-215.1(b)]
a. The Permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed
below. One scan must be performed in each of the following years: 2022, 2023, and 2024.
Analytical methods shall be in accordance with 40 CFR Part 136 and shall be sufficiently sensitive
to determine whether parameters are present in concentrations greater than applicable standards
and criteria. Samples should be collected with one quarterly toxicity test each year, and must
represent seasonal variation [i.e., do not sample in the same quarter every year]. Unless
otherwise indicated, metals shall be analyzed as "total recoverable."

Supplemental-Form
d. 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
122.210)(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
Or, results can be sent to the email, ATForms.ATB@ncdenr. og_v.
Contact the Divisions 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.(4.) NOTIFICATION OF WASTEWATER DIVERSION TO HOLDING PONDS
[G.S. 143-215.1(b)]
To facilitate efficient tertiary filters operations, high flow surges of wastewater are occasionally
diverted to the holding ponds and thus relieve potential overflow at the tertiary filter. Eventually the
wastewater is returned to the treatment process. The permittee must alert the Wilmington Regional
Office, Surface Protection Group by phone within 48 hours of each diversion event at (910) 796-7215.
The permittee caller may be connected to the Wilmington Regional Office voice mail system. At a
minimum the permittee shall report the following:
a) State: " I am alerting the Surface Water Protection Group about a holding pond diversion event
at Chadbourn WWTP"
b) State the person's name making this call
c) State the date, time, and duration of the diversion event
d) State, if known, the anticipated date, time, and duration to return the collected wastewater in
the pond(s) back to the treatment process.
The Wilmington Regional Office may request additional information or conduct further follow up.

Permit NCO021865
A.(5.) ELECTRONIC REPORTING OF 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 I1 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 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

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.
NPDES Electronic Reporting Rule - Phase 2 Extension. EPA is proposing to extend the Phase 2
deadline from December 21, 2020, to December 21, 2025. The current compliance date will be
extended if the implementation date is extended as a final regulation change in the federal register.
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 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
