Subject: NPDES PERMIT ISSUANCE
NPDES Permit NCO085553
Bald Head Island WTP
Class PCNC
Brunswick County
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached final NPDES discharge permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15,
2007 (or as subsequently amended).
The final permit includes the following significant changes from the existing permit:
➢ Section A. (4) has been added to require electronic submission of effluent data, and a footnote
has been added in Section A. (1). Federal regulations require electronic submittal of all
discharge monitoring reports (DMRs).
➢ Regulatory citations have been added to the permit.
➢ Outfall map has been updated.
➢ The facility name has been updated on the permit cover sheet to reflect the Divison's records.
➢ Language has been updated on the Supplement to Permit Cover Sheet based on current NPDES
permit formatting.
➢ Flow measurement frequency has been changed from weekly to continuous and sample type
changed from recorder to recording based on the maximum monthly average flow between April
2014 and April 2017 per the current water treatment plant strategy. Membrane technology water
treatment plants require continuous recording monitoring for facilities discharging > 50,000
GPD.
➢ Monitoring for temperature is no longer required, therefore it has been removed from Section A.
(1).
➢ Monitoring, limits, and an associated footnote have been added for total residual chlorine per the
current water treatment plant strategy.
➢ Monitoring has been added for turbidity per the current water treatment plant strategy
➢ Measurement frequency for pH at the effluent has been changed to 2/month per current water
treatment plant strategy.

Mr. Chris McCall
NC0085553 Issued Permit
➢ Limits have been added for Total Copper and Total Zinc based on a reasonable potential to
exceed water quality standards, and monitoring frequency has been changed to monthly.
➢ Monitoring has been added for Total Nitrogen and Total Phosphorus per the current water
treatment plant strategy.
➢ "Monitor & Report" has been added to Whole Effluent Toxicity Monitoring in the effluent table
in Section A. (1).
➢ The footnote for toxicity in Section A. (1) has been updated.
➢ A Discharge Alternatives Evaluation has been added as Section A. (3) due to a history of failed
toxicity tests.
The final permit includes the following significant changes from the draft permit:
➢ Instream monitoring for pH has been separated from effluent monitoring and the instream
monitoring frequency reduced to monthly per the current water treatment plant strategy.
Whole Effluent Toxicity test results submitted during the past three years have demonstrated that the
Water Treatment Plant's effluent is showing potential for causing aquatic toxicity in the receiving
stream. As a result, the Village of Bald Head Island shall perform a Discharge Alternatives Evaluation
as described in Section A. (3) of this permit. This evaluation is being requested to determine whether
there are any economical and technologically feasible alternatives available to the Village of Bald Head
Island to comply with all NC Water Quality Standards. The permittee will be given approximately one
permit cycle to evaluate and document possible treatment/discharge alternatives to eliminate aquatic
toxicity. The evaluation shall be submitted with the permittee's next permit renewal application and will
be carefully reviewed by the Division and the results will be used in the development of a compliance
schedule or possible variance request for the Village of Bald Head Island.
With the renewal application, a cover letter requested the removal and/or reduction of upstream and
downstream sampling requirements for conductivity and salinity. Per the current water treatment plant
strategy, monthly monitoring is required of conductivity and salinity. Therefore, these parameters will
remain in the permit at a measurement frequency of monthly.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such
demand is made, this permit shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain any other Federal, State, or Local governmental permit that may be required.
If you have any questions or need additional information, please do not hesitate to contact Brianna
Young of my staff at [phone].

Page 3 of 9

Permit NCO085553
A. (2) ACUTE TOXICITY MONITORING (QUARTERLY)
[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). Effluent samples for self-monitoring purposes must be obtained during representative effluent
discharge below all waste treatment. The tests will be performed during the months of January, April,
July, and October. These months signify the first month of each three month toxicity testing quarter
assigned to the facility.
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, DWQ Form AT -2 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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
Environmental 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. Upon submission of a valid test, 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 Quality indicate potential impacts to the receiving stream, this permit may be re -opened
and modified to include alternate monitoring requirements or limits.
Page 4 of 9

Permit NCO085553
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation and reporting of the data submitted on the DMR and AT
Forms.
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.
USE OF A DIFFERENT TEST ORGANISM
The permittee may request the use of a different test organism upon documentation that the alternate test
organism would provide an equal or greater level of protection and is appropriate based on the
characteristics of the discharge and receiving stream. Such documentation would consist of one of the
following:
1. For saltwater classified streams, a fathead minnow may be assigned as the acute testing species if
the salinity of the receiving stream at the point of discharge is <5 ppt throughout the tidally
influenced cycle. This determination may be based on the best professional judgment of DWQ
staff or data collection provided by the permittee and approved by DWQ staff. This evaluation
should include vertical profiles of salinity/conductivity measurements at both high tide and low
tide over several 24 hr cycles.
2. Three consecutive "side-by-side" tests with results indicating that the alternate test organism is as
or more sensitive to the facility's effluent. Each test series would consist of two separate toxicity
tests conducted on the same sample of effluent with the length of exposure specified by the permit,
the only difference between the tests being the organism used.
3. An alternate plan developed by the permittee and approved by the Aquatic Toxicology Unit that
demonstrates an equal level of protection is offered by the test organism.
For items 2 and 3, it must also be demonstrated that viable and standardized culture techniques are
available for that organism and standardized testing methodologies have been developed and
validated. This demonstration should meet guidance provided by EPA in Section 6 of EPA -821-R-02-
012, Short Term Methods for Estimating the Acute Toxicity of Effluents and Receiving Waters to
Freshwater Organisms. Fifth Edition, 2002.
A. (3) DISCHARGE ALTERNATIVES EVALUATION
The Permittee shall assess potential alternatives to eliminate Whole Effluent Toxicity (WET) test failures.
This evaluation shall assess the feasibility of all the following alternatives.
1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged to a wastewater
treatment plant. Approval or disapproval from the plant operator should be acquired.
2. Obtain a Non -discharge permit: Eliminate the surface water discharge by obtaining a non -discharge
permit for spray irrigation, infiltration, or subsurface disposal (on-site drainfield,
infiltration gallery, injection wells).
Page 5 of 9

Permit NCO085553
3. Install Wastewater Treatment: Install improved wastewater treatment to enable the facility effluent to
consistently pass the WET test. If this is not technically feasible or cost prohibitive,
please explain and provide estimated costs.
4. Use Alternative Water Treatment Source: Obtain drinking water from another source (nearest
County, City, or Town or other wells) so the discharge or toxicity problem is
eliminated.
5. Use Alternative Water Treatment Method: Install alternative and/or innovative water treatment
methods or operational improvements that do not produce toxic wastewaters. For
example, install a recycle iron/manganese filtration system with no discharge or
combine discharge with WWTP or cooling water effluents.
6. Discharge to a Larger waterbodv/Perform a dilution model: Relocate the facility's discharge to a
larger receiving waterbody to eliminate or reduce toxic impacts to the receiving
waterbody given the increased dilution. If applicable, perform a dilution model to
receive allowance for stream dilution in WET test.
7. Combination of Alternatives: Employ any combination of the alternatives listed above that would
result in eliminating or decreasing toxicity until a more feasible solution becomes
available.
The evaluation shall include a present value of costs analysis for all technologically feasible options as
outlined in the Division's "Engineering Alternatives Analysis Guidance Document." This Document can be
found at: htti)://Portal.ncdenr.org/web/wq/sLvp/Ts/Udes/Termits.
This evaluation is being requested to determine whether there are any economical and technologically
feasible alternatives available to the Permittee to address aquatic toxicity in the plant effluent. Based upon
the evaluation, please identify viable alternatives and present an implementation schedule and project
timeline for the preferred alternative. The Permittee shall submit the Discharge Alternatives Evaluation to the
Division along with the submission of their next permit renewal application (due 6 months prior to permit
expiration on November 30, 2022) to:

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 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)].

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 the
