SUBJECT: Startup Inspection Report
Stateside WWTP
Non -discharge Permit No. WQ0035809
Onslow County
Dear Permittee:
The North Carolina Division of Water Resources conducted the startup inspection of the Stateside
WWTP on 8/29/2019 to verify that the facility can operate in compliance with the conditions and
limitations specified in Non -discharge Permit No. WQ0035809. The findings and comments noted
during this inspection are provided in the enclosed copy of the inspection report entitled "Compliance
Inspection Report". Please read carefully all the sections of the CIR in order to address in any items
that require attention.
Please respond in writing to this office within 30 days of your receipt of this letter regarding your plans
or measures to be taken to address the following issues:
*Evaluate thick cake layer on the surface of the tanks: On inspection day, it was observed a thick cake
layer on the surface of the pre -anoxic #I, membrane, and sludge holding tanks. The WiRO
recommends contacting the manufacturer to determine if the cake layer as formed, more particularly
on top of the membrane tank, reflects a normal operation. Because of the thickness of the cake layer,
mixing in the pre -anoxic tank #1 was almost imperceptible. Similarly, aeration in the sludge holding
tank was not apparent.
*Track high total phosphorus concentrations: Mr. Jeff Jarman (ORC) commented that total
phosphorus (TP) concentrations from two sample events were high (TP-7 mg/1- permit limit= 2 mg/1)

and that the plan was to start chemical addition (alum) for TP removal. It would be useful to
investigate if the cake thick layer (i.e. old sludge?) would be contributing to the high TP.
*Install staff gauge in high -rate infiltration basin #5: High -rate infiltration basin #5 started operation.
On inspection day, the staff gauge for freeboard recording had not been installed. Mr. Jarman
indicated that the provider requires 2 weeks for delivery. Once the staff gauge is available, levels in
the basin must be reshot. Please provide a picture of the gauges when installed.
•Update infiltration capacity calculations: Please provide updated calculations for the infiltration
capacity of basin #5. The calculation report in our files is from November 2011. Also, provide a
schedule of the plans for the evaluation of basins #3 and #4.
•Provide a map with the review and compliance boundaries: Please provide a map showing the
delineation of the review and compliance boundaries and the location of the water supply well that
was used to provide water for the basin's test. Determine if the water supply well is within the
compliance boundary. On 09/03/2018, Mr. Stewart provided a map with the approximate location
of the well. Verification of the location of the well related to the compliance boundary is required
since the well must be abandoned (if located within the compliance boundary) and records (GW-30)
submitted to the Wilmington Regional Office.
*Provide site -specific narrative for the operation of the Stateside WWTP and Operators training:
WiRO reviewed the O&M plan provided by the WWTP consultant, and noticed that the document is a
compilation of printouts from the manufacturers of the many components of the plant. It has a
general information section on mmf systems which does not describe the specific operating (i.e.
chemical addition, MLSS operating concentration, flow recirculation, etc.) conditions for the Stateside
WWTP. The writer requested on an e-mail to Envirolink on 09/26/2019, to provide a narrative
describing the operation of this system which would also help the operators' training in this new
membrane technology. The narrative must be tailored to this site. WiRO emphasizes the need of
the operators' training.
If you should have any questions, please do not hesitate to contact Morella Sanchez -King with the Water
Quality Regional Operations Section in the Wilmington Regional Office via email at
[e-mail].

Inspection Summary:
Two inspections (preliminary inspection: July 15 and start up inspection: August 29, 2019) were conducted to document the
progress of the membrane bioreactor (MBR) wastewater treatment plant towards full operation. On July 15, 2019 the
following personnel were present for the inspection, (1) for the permittee and its consultants: Robert Burgin, Chuck Donnel,
and Jeff Jarman, (2) for the Division of Water Resources/ Wilmington Regional Office (WiRO): Geoff Kegley, Helen Perez,
Morella Sanchez King, and Tom Tharrington. On August 29, 2019 the following personnel were present for the inspection: (1)
for the permittee and its consultants: Chuck Donnel and Jeff Jarman, (2) for the DWR/ WiRO: Morella Sanchez King and
Bryan Lievre. The Division of Water Resources appreciates Old North State staff and consultants for the assistance
provided during both inspections.
The Stateside WWTF comprises the wastewater treatment plant and three high -rate infiltration basins for effluent disposal.
Biological treatment is provided by a MBR, type: "Max Flow Membrane Filtration" (mmf). The treatment system consists of
the following components: contact fine screen, equalization, oxic, anoxic II, anoxic I, membrane (mmf system), sludge
holding, and pumps, blowers, SCADA system. On both inspection days, it seemed that all components of the system were
in place, as described in the permit. The disposal system consists of three high -rate infiltration basins (numbered: 3, 4, and
5). The three basins have been constructed, but only one is in operation.
The Stateside 100,000 GPD- WWTP received full certification by Robert G. Burgin, PE in January 2019 while the disposal
system was partially certified by Timothy M. Stewart, PE in June 2019. Mr. Stewart tested and certified basin #5 for a
capacity of 50,000 GPD. Basins 4 and 5 should not be used until tested and certified. Therefore, the capacity of the
system is limited to the disposal capacity of 50,000 gpd.
Below is a summary of the items that were discussed during the preliminary inspection on 7/15/2019 and that have been
resolved:
• Continue pumping and hauling. On inspection day, the plant was not ready to process domestic wastewater until its
start-up authorization.
• Further testing and process control adjustments should be performed with clean water. Since a startup inspection had not
been performed, sewage water could not be used during the testing period.
• Do not discharge to any of the infiltration basins. Infiltration Basin #5 could be used after certification and monitoring wells
sampling.
• Configure the groundwater lowering system discharge so that it discharges to the appropriate outlet structure and include
permanent abandonment of the temporary GW lowering discharge pipe (the discharge without the flow meter).
• Provide evidence of the calibration of all meters, probes, etc.
• Influent pump station: needed cleaning, there was an excess of grease/solids/debris covering 100% of the water surface.
Provide identification, address, and contact phone number at the gate of the pump station.
Timeline of activities after preliminary inspection on 07/15, towards the facility start up:
• The WWTP was seeded on July 31 st and the consulting engineers established automatic operation of the facility on that
date
• On August 1st Envirochem was on -site to take samples of WWTP effluent, monitoring wells and groundwater lowering
effluent. The Upstream and downstream samples from Margaret Branch could not be taken as it was dry.
• On August 1 st the flowmeters associated with the site were inspected and calibrated by a contract vendor.
• As of August 15th, results of the sampling event had not been received at the WiRO, but weekly conversations with the
ORC indicate the facility is operating as designed.
The startup Inspection on 08/29/2019 was to verify the operation of the WWTP, disposal area (basin #5), and sampling
points. Jeff Jarman (ORC) and Chuck Donnel with Envirolink provided assistance to DWR inspectors, Morella Sanchez King
and Bryan Lievre. We are providing the following observation and/or comments:

Inspection Date: 08/29/2019 Inspection Type : Compliance Evaluation Reason for Visit: Routine
• The influent pump station is now working. On inspection day, it looked well maintained, with signage for contact
information at the gate. The high water alarm and generator worked well when a high water and power shutoff were
simulated. Water supply at the P.S. needs to be installed.
• The plant was seeded at the aerated equalization basin with sludge from the Carolina Plantations WWTP (WQ0033770).
High water alarm in the equalization basin did not operate on inspection day. Flow through the plant is averaging 17,000 gpd.
On inspection day, the flow was—14,000 gpd.
• Flow is being diverted from the equalization basin directly to pre -anoxic tank I, then flow is pumped to the membrane tank
where it has two options (1) flow continues through the membrane treatment; or (2) flow can return via gravity to the
pre -anoxic I, and pumped back to the membrane tank (making an anoxic -membrane cycle -anoxic). Pre -anoxic tank II and
oxic tanks have not been used.
• It was observed a thick cake layer on the surface of the pre -anoxic I, membrane, and sludge holding tanks. The WiRO
recommends contacting the manufacturer to determine if the cake layer as formed, more particularly on top of the
membrane tank, reflects a normal operation. Because of the thickness of the cake layer, mixing in the pre -anoxic tank I was
almost imperceptible. Similarly, aeration in the sludge holding tank was not apparent.
• Mr. Jarman commented that total phosphorus (TP) concentrations from two sample events were high (TP-7 mg/1- permit
limit= 2 mg/1) and that the plan was to start chemical addition (alum) for TP removal. It would be useful to investigate if the
cake thick layer (i.e. old sludge?) would be contributing to the high TP.
• DO and pH measurements are taken with portable meters. MLSS range is from 6,000-7,000 mg/I. Please check with the
manufacturer the ideal range of operation for MLSS, TSS, excess sludge removal.
• There are no (current) plans for carbon addition (Micro C).
• Sampling points for the effluent (PPI 001) and groundwater lowering system were inspected (the surface water sampling
points on Margaret Branch were not visited). The two LIV units for disinfection were in operation. The effluent looked clear
and odorless.
• High -rate infiltration basin #5 started operation. On inspection day, the staff gauge for freeboard recording had not been
installed. Mr. Jarman indicated that the provider requires 2 weeks for delivery. Once the staff gauge is available, levels in
the basin must be reshot.
• Please provide a map showing the location of the water supply well and the delineation of the review and compliance
boundaries. Determine if the water supply well is within the compliance boundary. If so, the well must be abandoned and
records (GW-30) submitted to the Wilmington Regional Office. On 09/03/2018, Mr. Stewart provided the approximate
location of the well which was used to provide water to the basins. Verification of the location of the well related to the
compliance boundary is required since the well must be abandoned, if it is located within the compliance boundary.
• Please provide updated calculations for the infiltration capacity of basin #5. The calculation report in our files is from
November 2011. Also, provide a schedule of the plans for the evaluation of basins #3 and #4.
• WiRO emphasizes to read and familiarize with the permits for the collection system and wastewater treatment plant to
ensure compliance. Attachments A, B, and C of the WWTF permit list the sampling points or reporting requirements for the
facility (effluent, groundwater lowering system, surface water monitoring at points upstream and downstream on Margaret
Branch, and high rate infiltration sites). For clarifications on the interpretation of the permit, location of sampling points,
recording requirements, or if non-compliance issues are foreseen, please contact Helen Perez (910 796 7323).
• WiRO also emphasizes the need of the operators' training in this new membrane technology for this specific site. WiRO
reviewed the O&M plan provided by the WWTP consultant, and noticed that the document is a compilation of printouts from
the manufacturers of the many components of the plant. It has a general information section on mmf systems which does
not describe the specific operating (i.e. chemical addition, MLSS operating concentration, flow recirculation, etc.) conditions
for the Stateside WWTP. The writer requested on an e-mail to Envirolink on 09/26/2019, to provide a narrative describing
the operation of this system. The narrative must be tailored to this site.
