Permit: WO0033770 Owner - Facility:Old North State Water Company LLC
Inspection Date: 03/10/2021 Inspection Type : Compliance Evaluation
Reason for Visit: Routine
Inspection Summary:
A routine compliance inspection of the Carolina Plantation WWTF was conducted on March 10, 2021. The purpose of the
evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit
W00033770. Jeff Jarman was present during the inspection.
The Carolina Plantation WWTF is a 150,000 gpd as built extended aeration treatment plant with four high -rate infiltration
basins for disposal. The current permit expires on December 31, 2021. A reminder that a renewal application is required to
be submitted six months prior to the expiration date.
This facility has had many issues that have not been addressed in several years. The last inspection on August 29, 2019
requested a written response of plans or measures to be taken to address these issues noted below. A response was not
received by our office.
1. The installation of the static fine screen with auger and dewatering press, which was part of the major modification in
2015, was never completed.
2. The effluent flow has been between 80-90% of the permitted flow of 150,000 gpd in 2016, 2017, 2018. In 2019-2020, the
flow has exceeded the limit or has been over 90% of permitted flow.
3. The bank of the infiltration basins continue to show signs of erosion.
4. Fecal coliform counts at the GW lowering system pump station have been sporatically high in 2019-2020. There is no
limit at this sampling site, but there is concern of the water quality protection of the two amenities ponds and ultimately to
Half Moon Creek.
These issues were still observed during this inspection and/or file review. Further more, Schedule 1.1 in the current permit
states that within 90 days of the effective date (April 1, 2017), the Permittee shall submit an Engineering Certification for the
modifications to the Phase 1 wastewater treatment facility that were permitted January 5, 2015. The majority of the
modification items do not appear to be completed and no certification has been received.
The facility is noncompliant with Non -Discharge Permit W00033770. A Notice of Violation will be issued. Please respond in
writing to this office within 30 days of your receipt of this letter regarding plans or measures to be taken to address the above
issues.

dewaterinq press assembly, EQ mixers, replacement of recycle aerobic tank pumps and
aerobic digester flat sheet membrane modules have not been added.

Comment: The effluent flowmeter was calibrated on 5-28-2020 by Delta Systems as well as all four
flowmeters measuring flow to each infiltration basin.

quarterly. During inspection, power was interupted and generator was activated and transferred
power to plant.

Comment: The manual bar screen requires alot of maintenance because it is located after the EQ basin.
Solids appear to escape the bar sceen and build up along the edge of every treatment unit.
Approximately every six weeks, floating solids are removed from the EQ basin and the treatment
units by vac truck. The installation of a static fine screen with auger and dewatering press was
part of the major modification permit issued on 1-15-2015 but was never installed. The inspector
from the last inspection on 8/29/2019 requested plans to address this issue. No response was
received.

Comment: A freeboard gauge in Basin #2 needs to be reinstalled. The banks of the infiltration basins need
maintenance to address erosion control. No response was received from last inspection on
plans or measures taken to address this issue as requested. A file review of fecal results of the
GW lowering for 2020 show many high values as found in the last inspection on 8-29-2019.
There is no permit limit for fecal for this sampling site. However, there was a request from the
inspector in the 8-29-2019 inspection report for measures planned or taken to address 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. No response was
received.
