Subject: Draft NPDES Permit NC0083321
Hubert WTP
Grade I Physical Chemical WPCS
Onslow County
Dear Mr. Hudson:
The Division has reviewed your request to renew the subject permit. Please review this draft carefully
to ensure your thorough understanding of the information, conditions, and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
1. Language has been updated in Section A. (1) and Section A. (5)to require electronic submission
of effluent data. Federal regulations require electronic submittal of all discharge monitoring
reports(DMRs).
2. Outfall map has been updated.
3. Regulatory citations have been added.
4. The permit expiration date has been updated to be in line with the basin schedule. The permit is
being short-cycled due to this.
5. Language on the Cover Sheet and Supplement to Permit Cover Sheet has been updated.
6. The facility grade has been added in Section A. (1).
7. Parameter units and codes have been added in Section A. (1).
8. The weekly average for total suspended solids in Section A. (1) has been changed to a daily
maximum as weekly averages are not used in water treatment plant permits.
9. Monitoring for temperature has been removed in Section A. (1) as this is no longer required per
the current water treatment plant guidance.
10. The pH monitoring frequency has been increased to 2/month in Section A. (1) per the current
water treatment plant guidance.
11. Instream pH monitoring has been added in Section A. (1) per the current water treatment plant
strategy, and was mistakenly removed during the previous permit renewal.
12. Instream monitoring for salinity and conductivity has been separated from effluent monitoring in
Section A. (1).
13. The effluent sample type for salinity and conductivity has been changed to composite in Section
A. (1). Per the current water treatment plant guidance, for Ion Exchange water treatment plants,
salinity and conductivity samples collected at the effluent should be composite samples.

14. Monitoring for total dissolved solids has been reduced and the sample type changed to composite
in Section A. (1). Per the current water treatment plant strategy, for Ion Exchange water
treatment plants,total dissolved solids collected at the effluent should be a composite sample.
15. Limits have been added for total copper and monitoring increased to monthly in Section A. (1)
based on a reasonable potential to exceed water quality standards.A compliance schedule has
been added as Section A. (3).
16. Limits have been added for total zinc and monitoring increased to monthly in Section A. (1)
based on a reasonable potential to exceed water quality standards. A compliance schedule has
been added as Section A. (3).
17. Monitoring and limits have been added for lead in Section A. (1) based on a reasonable potential
to exceed water quality standards. A compliance schedule has been added as Section A. (3).The
previous permit removed lead monitoring based on a reasonable potential analysis; however,this
analysis did not account for the high quality waters(HQW)classification of the receiving stream.
Removal can be considered at the next permit renewal.
18. Updated the footnotes in Section A. (1).
19. Updated permit conditions under effluent table in Section A. (1).
20. Updated toxicity test in Section A. (2). Due to an extended history of failed toxicity tests,the
toxicity test has been changed from a monitor only test to a limit test.
21. The discharge alternatives evaluation in Section A. (3)has been updated.
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 Onslow Water and Sewer Authority 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 Onslow
Water and Sewer Authority to comply with all NC Water Quality Standards. The permittee will be
given six(6) months from issuance of the final permit to evaluate and document possible
treatment/discharge alternatives to eliminate aquatic toxicity.The evaluation shall be submitted and
will be carefully reviewed by the Division.
Please note that the practical quantitation limits(PQLs) for Total Copper and Total Lead are 2 µg/L, and
the PQL for Total Zinc is 10 µg/L (per the Inorganic Chemistry Branch of the Division of Water
Resources Water Sciences Section)and monitoring data should be reportable down to these levels. Per
North Carolina 15A NCAC 02B Water Quality Standards for Surface Waters, the current limits for class
SA;HQW waters for copper are 2.90 µg/L (acute) and 1.85 µg/L (chronic), for lead are 110.40 µg/L
(acute)and 4.25 µg/L (chronic), and for zinc are 47.6 µg/L (acute)and 42.8 µg/L (chronic). Limits for
water treatment plants are determined by evaluating DMR data submitted to the Division, along with a
dilution factor(if applicable)and the maximum monthly average flow reported in the previous 3 years at
the time the review is completed.
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, has been added to this permit at a monitoring frequency of quarterly. See Section A. (1)
Effluent Limitations and Monitoring Requirements.
With this notification, the Division will solicit public comment on this draft permit by publishing a
notice in newspapers having circulation in the general Onslow County area, per EPA requirements.
Please provide your comments,if any,to me no later than 30 days after receiving 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 the draft, please
contact me at 919-707-3619, or via e-mail [[e-mail]].

Permit NC0083321
A. (2) ACUTE TOXICITY PASS/FAIL 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 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 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
Page 5 of 10

Permit NC0083321
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. (3) DISCHARGE ALTERNATIVES EVALUATION
[15A NCAC 02H .0105]
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).
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: https://deq.nc.gov/about/divisions/water-resources/water-quality-permitting/npdes-
