A. (3.) TOTAL NITROGEN MONITORING
[G.S. 143-215.1(b)]
The permittee shall calculate total annual nitrogen mass loading as the sum of monthly loadings,
according to the following equations:
(1) Monthly Loading(pounds) =Days x TN x Qw x 8.34
where:
Days=the number of days of discharge in that month
TN = the average total nitrogen concentration(mg/L)of the
composite samples collected during the month
Qw =the average daily waste flow(MGD) for the month
8.34 =conversion factor, from(mg/L x MGD)to pounds
(2) Annual Mass Loading (pounds/year) = Sum of Monthly Loadings(pounds per month)for the
calendar year
Each month, the permittee shall report the total nitrogen concentration for each sample and the monthly
mass loading in the appropriate discharge monitoring report(DMR); and report the annual total nitrogen
mass loading in the December DMR each year.
A. (4.) LIMITS FOR TOTAL ANNUAL NITROGEN
[G.S. 143-215.1(b)]
A total annual nitrogen limit is applied annually for compliance purposes. The total annual nitrogen load
limit has been calculated using a total nitrogen concentration of 5.5 mg/L at 15.0 MGD. This annual load
is subject to change should water quality in the vicinity of this discharge indicate that more stringent
controls for nutrients are warranted.
A. (5.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
[15A NCAC 02B.0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Mysidopsis bahia at an effluent concentration of 5%.
The permit holder shall perform at a minimum, quarterly monitoring using procedures described below
to establish compliance with the permit condition. 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. 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. The test procedure will be based on EPA Method 1007.0, Mysid,
Mysidopsis bahia, Survival, Growth, and Fecundity Test, as described in Short-Term Methods for
Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms,
Third Edition, EPA-821-R-02-014. The procedure will be performed as written with the following
exceptions:
Page 6 of 14

Permit NC0063029
• The test treatments will consist of a control and a 5% effluent concentration.
• Mortality for pass/fail tests will be evaluated using the t test described in Section 11.3 in
Methods for Measuring the Acute Toxicity of Effluents to Freshwater and Marine
Organisms, Fifth Edition. EPA-821-R-02-012, October 2002, applying an alpha level
of 0.05.
• The growth endpoint for pass/fail tests will be determined using Appendix G of Short-Term
Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine
and Estuarine Organisms, Third Edition, EPA-821-R-02-014, October 2002, applying an
alpha level of 0.01.
• Mortality and growth endpoints for multiple-concentration tests will be determined using
hypothesis testing as described in EPA Method 1007.0,Mysid,Mysidopsis bahia,Survival,
Growth, and Fecundity Test, as described in Short-Term Methods for Estimating the
Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms,
Third Edition, EPA-821-R-02-014, October 2002.
• Fecundity will not be evaluated.
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. For pass/fail results,
report using the parameter code TGP3E and the DWR Form AT-4 (original), which is to be sent to the
address below.

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, monitoring
will be required during the following month.Upon submission of a valid test,this monthly test requirement
will revert to quarterly in the months specified above. 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.

to the NPDES Permitting Unit.
A. (7.) TACTICAL WATER PURIFICATION SYSTEM TESTING
The facility may discharge effluent from a mobile tactical water purification system (TWPS) as needed
under the following conditions:
• The separated treated water stream and the saline brine stream must be combined prior to discharging
back to the original water source.
• Any backwash from the reverse osmosis element and the microfiltration filter must be collected and
treated at the Camp Lejeune Advanced Wastewater Treatment Plant, in accordance with the terms and
conditions of this permit.
• The only chemical allowed to be added to the water during TWPS testing is an antiscalant. It must be
captured in the backwash waste stream.
• The objective of the training exercise is to practice operating the mobile water purification unit,rather
than generating potable water for actual consumption.
Page 9 of 14

Permit NC0063029
• The chlorine injection system included with each TWPS unit will be exercised by passing water,rather
than liquid calcium hypochlorite, into the TWPS product water.
• The permittee must discuss any deviations from these conditions with the Division prior to discharge.
• Written notification of proposed TWPS testing must be made to the Division's Wilmington Regional
Office, Surface Water Protection Section at least two weeks prior to the testing. This notification must
include the location and dates scheduled for the testing.
A. (8.) GROUNDWATER REMEDIATION DISCHARGES RESTRICTION

[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.) (all
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, 2025, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
Page 11 of 14

Permit NC0063029
• 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: htips://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
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.

Briefly describe the proposed permitting action and facility background:United States Marine Corps Base,
Camp Lejeune(MCB CAMLEJ),herein called MCP CAMLEJ or Permittee,applied for an NPDES permit
Major Modification for Camp Lejeune Advanced Wastewater Treatment Plant(WWTP).The modification
is necessary to incorporate a waste stream from the mobile PFAS treatment system. The system will be
moved around the site to treat aqueous PFAS impacted construction or operational wastes, including
groundwater and rinsate from cleaning contaminated tanks/systems.
The wastewater will be pre-treated for iron, as necessary, followed by GAC, and Ion Exchange treatment
for PFAS.The wastewater will be run through the system until PFAS are below EPA health advisory levels
(PFOA + PFOS < 70.0 ng/L). The treatment system will operate in batches and will utilize frac tanks to
allow effluent sampling prior to discharge. The proposed flow rate is 10 gpm. The effluent from the PFAS
treatment system shall be discharged via Internal Outfall 002 to Outfall 001.
Camp Lejeune Advanced WWTP is a state-of-the-art facility that began operation in 1998 and consolidated
seven discharges.The facility serves Marine Corps Base Camp Lejeune and Marine Corps Air Station New
River with a total population of 148,000. The facility's average discharge for the period of January 2014
through June 2019 was 4.4 MGD which accounts for—29%of the plant's capacity.
MCP CAMLEJ receives waste streams from Onslow Water and Sewer Authority (ONWASA), Naval
Medical Center(NMC),Oil Water Separators(OWS),Municipal Solid Waste Landfill Facility(MSWLF)
leachate, Solid Waste Compost Facility (SWCF) runoff, four Water Treatment plants (WTPs) filter
backwash and seven remedial treatmentplants. The remediation systems include: Installation Restoration
(IR) Site 78 North, IR Site 78 South, AS-4141, HPFF South East Compound, New River PPV, TC-341
Pipeline and Rapid Refueler (attached the description of each site). RCRA Sites AS-4141 and Rapid
Refueler have been shut down since the discovery of Per-and Polyfluoroalkyl Substances(PFAS)in their
effluent.No other sources of PFAS have been identified flowing to the facility.
According to 2007 White Oak River Basin Plan,Nutrient enrichment has been a significant problem in the
estuarine portions of the New River, and periodic elevated fecal coliform bacteria l v l
s also appear to be
a recurring problem in this subbasin(03-05-02). High nutrient levels were being discharged by the City of
Jacksonville as well as Camp Lejeune. In 1998, Jacksonville removed its discharge from the upper New
River estuary and Camp Lejeune consolidated its seven discharges into one tertiary treatment facility.These
discharges were considered a major source of nutrients into the upper estuarine portions of the New River.
As a result,a reduction of nitrogen and phosphorous, 57 and 71 percent respectively,has occurred.
