Subject: Draft NPDES Permit
Permit NC0003816
USMCAS Cherry Point WWTP
Craven County
Grade IV WPCS
SIC Code 4952
Enclosed with this letter is a copy of the Draft NPDES permit 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:
• Effluent mercury data was reviewed from March 2015 to March 2019. In accordance with
the 2012 Mercury TMDL NPDES Guidance the Permittee needs to show annual average
effluent concentrations below the Water Quality Based Effluent Limitation (WQBEL) and
the individual mercury sample result below the Technology Based Effluent Limitation
(TBEL). A review of the data showed that both criteria were met; therefore, mercury
limitations and monitoring have been removed from the permit [See A. (L) and A. (2)].
• Based on the Mercury TMDL evaluation, Mercury Minimization Plan (MMP) special
condition has been removed from the permit.
• Total Residual Chlorine (TRC) daily maximum limit for outfall 001 has been changed to
13 µg/L based on the US EPA NRWQC for saltwater aquatic life protection [See A. (L)
and A. (2)]. Please note that the Division shall consider all effluent TRC values reported
below 50 µg/L to be in compliance with the permit.
• The Permittee reported Total Copper and Total Zinc at less than detection, with detection
levels < 50.0 µg/L for Total Copper and Total Zinc. The allowable monthly discharge
concentrations for your facility are 26.4 µg/L for Total Copper and 575.6 µg/L for Total
Zinc. DWR's laboratory identifies the target Practical Quantification Limits (PQLs)
for Total Copper and Total Zinc as 2.0 µg/L and 10.0 µg/L, respectively. In accordance
with 15A NCAC 2B .0500 all test procedures must produce minimum detection and
reporting levels that are below the allowable discharge concentration and all data generated
must be reported down to the minimum detection level or lower reporting level of the
North Carolina Department of Environmental Quality I Division of Water Resources

procedure. The Permittee should use sufficiently sensitive test methods when analyzing
effluent data, including performing Effluent Pollutant Scans. Following is a link to DWR's

• Some of the wording has changed in Special Condition A. (6), Chronic Toxicity Permit
Limit, please review each paragraph carefully.
• Language of Special condition A. (10.), Electronic Reporting of Discharge Monitoring
Reports, has been updated. Please review each paragraph carefully.
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
and Instream Monitoring Requirements [See A. (1.), A. (2), A. (3), A. (4.) and A. (5)].
• Regulatory citations have been added to the permit.
The NPDES standard conditions (Parts II and III) 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 Craven 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) 707-3607 or by email at Qais.Banihani@ncdenr.gov.

WWTP (Outfall 001) and WTP (Outfall 002) effluent discharge at Outfall C01 shall at no time exhibit
observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent
concentration of 7 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or "North Carolina Phase II 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 on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter
code TGP3B for the pass/fail results and THP311 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
1623 Mail Service Center
Raleigh, NC 27699-1623
Or, results can be sent to the email, ATForms.ATB(ancdenr.gov.
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
Page 11 of 17
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. (7.) CALCULATION OF TOTAL NITROGEN LOADS
[G.S. 143-215.1(b)]
a. The Permittee shall calculate monthly and annual TN Loads as follows:
Monthly TN Load (pounds/month) = TN x TMF x 8.34
where: TN = the average Total Nitrogen concentration (mg/L) of the composite
samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the month
(MG/month)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN Load (pounds/year) = Sum of the 12 Monthly TN Loads for the calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and pounds/month) in the
appropriate discharge monitoring report for each month and shall report each year's results
(pounds/year) with the December report for that year.
A. (8.) ANNUAL LIMITS FOR TOTAL NITROGEN
[G.S. 143-215.1(b)]
a. Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse River
basin apply on a calendar year basis.
b. For any given calendar year, the Permittee shall be in compliance with the annual TN Load limit in
this Permit if. V
i. the Permittee's annual TN discharge is less than or equal to its TN Load limit, or
ii. the Permittee is a co-permittee member of a compliance association.
C. If the Permittee is not a co-permittee member of a compliance association and the Permittee's
cumulative annual TN discharge exceeds the effective TN Load limit in this permit at any point
during the calendar year, the Permittee is in violation of its TN Load limit, and each day of a
continuing violation shall constitute a separate violation.
Page 12 of 17
d. The TN Load limit in this Permit (if any) may be modified as the result of allowable changes in the
Permittee's TN allocation.
i. Allowable changes include those resulting from purchase of TN allocation from the Wetlands
Restoration Fund; purchase, sale, trade, or lease of allocation between the Permittee and other
dischargers; regionalization; and other transactions approved by the Division.
ii. The Permittee may request a modification of the TN Load limit in this Permit to reflect
allowable changes in its TN allocation. Upon receipt of timely and proper application, the
Division will modify the permit as appropriate and in accordance with state and federal
program requirements.
iii. Changes in TN limits become effective on January 1 of the year following permit
modification. The Division must receive application no later than August 31 for changes
proposed for the following calendar year.
iv. Application shall be sent to:
NCDWR / NPDES Programs
Attn: Neuse River Basin Coord'
1617 Mail Service Center
Raleigh, NC 27699-1617 .,
e. If the Permittee is a member and co-permittee of an approved compliance ciation, its TN
discharge during that year is governed by that association's group NPDES permit and the TN limits
therein.
i. The Permittee shall be considefed a Co-Pennittee Member for, any given calendar year in
which it is identified as such in Appendix A of the association group NPDES permit.
ii. Association roster(s) and members' TN allocations will be updated annually and in
accordance with state and federal program requirements.
iii. If the Permittee intends to join or leave a compliance association, the Division must be
notified of the proposed action in accordance with the procedures defined in the association's
NPDES permit.
(A) Upon receipt of timely and propernotification, the Division will modify the permit as
appropriate and in accordance with state and federal program requirements.
(B) Membership changes in a compliance association become effective on January 1 of the
year following modification of the association's permit.
f. The TN monitoring and reporting requirements in this Permit remain in effect until expiration of
this Permit and are not affected by the Permittee's membership in a compliance association.
A. (9.) TOTAL NITROGEN ALLOCATIONS
[G.S. 143-215.1(b) ]
a. The following table lists the Total Nitrogen (TN) allocation(s) assigned to, acquired by, or
transferred to the Permittee in accordance with the Neuse River nutrient management rule (T15A
NCAC 02B .0234) and the status of each as of permit issuance. For compliance purposes, this table
does not supersede any TN limit(s) established elsewhere in this permit or in the NPDES permit of

A. (10.) 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 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 ISugersedes Section D. (2.) and Section E. (5.) (a)1
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 electronicalIL, using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and si#6t 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), p�ennittees 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
Page 14 of 17
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 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.federalre i� ster.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.
