SUBJECT: Compliance Inspection Report
Carolina Plantation WWTP
Non -discharge Permit No. WQ0033770
Onslow County
Dear Permittee:
The North Carolina Division of Water Resources conducted an inspection of the Carolina Plantation WWTP on
8/29/2019. This inspection was conducted to verify that the facility is operating in compliance with the
conditions and limitations specified in Non -discharge Permit No. WQ0033770. The findings and comments
noted during this inspection are provided in the enclosed copy of the inspection report entitled "Compliance
Inspection Report". Please read the CIR in its entirety to address any issues noted. The facility is marginally
compliant with permit conditions.
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:
• Headworks: The current configuration of the headworks is problematic since the bar screen is located
after the equalization basin. Wastewater flow is pumped from the influent pump station to the
equalization basin and then to the bar screen. This requires daily scrapping of the bar screen, constant
cleaning of the EQ basin, and potential escape of solids to the clarifier. The installation of the static fine
screen with auger and dewatering press is still pending (also listed as pending in the September 2017
Inspection Report).
• Effluent Parameters (PI 001): WiRO performed a file review for the period 2016-2019. Except for flow
through the facility, the plant has been in compliance with the permit parameters. Regarding flow
violations, the facility exceeded the monthly average flow in June and July 2019 (168,964 and 151,185.61
gpd, respectively). The average flow from January through July is 96% of the permitted flow of 150,000
gpd for Phase I. In 2016, 2017, and 2018, the average calendar year flow was 88, 83, and 89% of the
permitted flow. Given these increasing flows, the DWR requests a report with the status of the plans for
expansion and a timeframe for execution.

• Infiltration Basins: The banks of the infiltration basin need maintenance: de -weeding and repairing areas
that are showing signs of erosion.
• GW Lowering System (PPI 002): Fecal coliform counts at the GW lowering system pump station are high.
In April, May, and Jun 2019 the FC counts were 291, 6706, and 157 col/100 ml, respectively (WiRO
acknowledges that there are no effluent limits at PPI 002). Given these high fecal coliform values, the
DWR requests taking measures (i.e. verify stormwater ponding at the entrance of the pump station,
disinfection, etc.) for the water quality protection of the two amenities ponds that receive water from the
GW lowering system that discharge into a man-made ditch, and ultimately to Half Moon Creek.
• GW level monitoring (piezometer reporting): Continue monitoring as indicated in the permit. To reduce
reporting, the WiRO suggests providing water level records three times a year, when sampling/reporting
the rest of the parameters.
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 at 910-796-7215 or via email at
[e-mail].

Inspection Date: 08/29/2019 Inspection Type : Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
A site inspection on August 29, 2019 and a file review were performed to verify if the facility was in compliance with the
conditions specified in permit WQ0033770. The following personnel were present during the site inspection: (1) for the
permittee: Chuck Donnel and Jeff Jarman, (2) for the DWR/ WiRO: Morella Sanchez King and Bryan Lievre. The Division of
Water Resources appreciates Mr. Donnel and Mr. Jarman for the assistance provided during the inspection.
Please review each section of the report. The following items need attention and a response:
1) Site Inspection
Headworks: The current configuration of the headworks is problematic since the bar screen is located after the equalization
basin. Wastewater flow is pumped from the influent pump station to the equalization basin and then to the bar screen. This
requires daily scrapping of the bar screen, constant cleaning of the EQ basin, and potential escape of solids to the clarifier.
The installation of the static fine screen with auger and dewatering press is still pending (also listed as pending in the
September 2017 Inspection Report).
Infiltration Basins: The banks of the infiltration basin need maintenance: de -weeding and repairing areas that are showing
signs of erosion.
2) File Review
Effluent Parameters (PI 001): WiRO performed a file review for the period 2016-2019. Except for flow through the facility, the
plant has been in compliance with the permit parameters. Reporting errors have been corrected. Regarding flow violations,
the facility exceeded the monthly average flow in June and July 2019 (168,964 and 151,185.61 gpd, respectively). The
average flow from January through July is 96% of the permitted flow of 150,000 gpd for Phase I. In 2016, 2017, and 2018,
the average calendar year flow was 88, 83, and 89% of the permitted flow. Given these increasing flows, the DWR requests
a report with the status of the plans for expansion and a timeframe for execution.
GW Lowering System (PPI 002): Fecal coliform counts at the GW lowering system pump station are high. In April, May,
and Jun 2019 the FC counts were 291, 6706, and 157 col/100 ml, respectively (WiRO acknowledges that there are no
effluent limits at PPI 002). Given these high fecal coliform values, the DWR requests taking measures (i.e. verify stormwater
ponding at the entrance of the pump station, disinfection, etc.) for the water quality protection of the two amenities ponds
that receive water from the GW lowering system that discharge into a man-made ditch, and ultimately to Half Moon Creek.
GW59: Groundwater monitoring: Except for sporadic TDS exceedances, all parameters are below the permitted limits.
GW level monitoring (piezometer reporting): Continue monitoring as indicated in the permit. To reduce reporting, the WiRO
suggests providing water level records three times a year, when sampling/reporting the rest of the parameters.

the equalization basin. Wastewater flow is pumped from the influent pump station to the
equalization basin and then to the bar screen. This requires daily scrapping of the bar screen,
constant cleaning of the EQ basin, and potential escape of solids to the clarifier. The installation
of the static fine screen with auaer and dewaterina press is still pendina (also listed in the

Comment: Flow (PPI-001): The permitted flow is 150,000 qpd (Phase 1). In 2019, The facility
exceeded the
monthly average flow in June (168,964 qpd) and July (151,185.61 qpd) the average
flow from
January- July is 96% of the permitted flow for Phase I. In 2016, 2017, and 2018, the average
calendar year flow was 88, 83, and 89% of the permitted flow. Given these increasing flows, the
DWR requests a report with plans for expansion and timeframe for execution.
GW Monitoring (GW-59). Except for sporadic TDS exceedances, all parameters are below the
permitted limits. GW level monitoring (piezometer reporting): continue monitoring as indicated
in the permit, but provide records three times a year, when sampling/reporting the rest of the
parameters.
GW Lowering System (PPI 002): Fecal coliform counts at the GW lowering system pump station
are high. In April, May, and Jun 2019 the FC counts were 291, 6706, and 157 col/100 ml,
respectively (Refer to the Summary section for details).
