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 treatment plants. 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 levels 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.
