Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
A routine compliance inspection of the Lake Waccamaw Wastewater Treatment Plant (WWTP), was
performed on March 6, 2024. The purpose of the inspection was to verify that the facility is operating
in compliance with the conditions and limitations specified within Permit NC0021881. Gregory Milliken,
facility Operator in Responsible Charge (ORC) and Talon Jacobs, back-up ORC were present during
the inspection.
The facility is a Grade II biological WWTP, currently permitted to receive up to 0.4 million gallons per
day (mgd) of wastewater and had an average daily flow of approximately 0.193 mgd in 2023. The
WWTP has:
- Manual bar screen & grit chamber
- Influent flow meter(for internal purposes) and composite sampler
- Activated sludge extended-aeration basin with 2 floating mechanical aerators
- Clarifier with sludge return (RAS) and sludge wasting (WAS)
- Two polishing ponds in series with a floating aerator in second pond
- Gaseous chlorine disinfection with contact chamber
- Dechlorination chamber (liquid calcium thiosulfate injection)
- Effluent flow meter and composite sampler
- Two aerated sludge holding tanks
- Sludge drying beds (backup)
- Emergency diesel-powered generator
The town has received grants and loans from DWI to complete three wastewater related projects, as
noted below:
1. The completion of a wastewater Asset Inventory Assessment (AIA)which is to include the
development of an Asset Management Plan (AMP)with Capital Improvement Plan (CIP), Operation
and Maintenance Plan, clean 10,000 LF of collection lines and video the lines, etc.
2. Lift Station Mitigation &WWTP Rehabilitation Project to include installation of generators at lift
stations A, 2, 13, 14 & 15 as well as improvements to the aeration basin including replacement of
shotcrete liner with 60 mm geomembrane liner, installation of two aerators in the polishing basin and
associated controls.
3. Phase 6 Sewer Improvements Project to include collection system repairs and WWTP upgrades.
The collection system repairs are to include the replacement of pump Stations A, B, C, 2, 13, 14, 15,
16, 17, replacement of 1,300 linear feet (LF) of 8" and 1,850 LF of 10" gravity sewer, replacement of
300 LF of 4"force main (@ PS#11), replace 13-4' manholes, and rehabilitation of 50-4' manholes.
The WWTP upgrades portion of the project is to include the replacement of the headworks consisting
of mechanical bar screen grit removal system and distribution box and installation of secondary
treatment train to include aeration basin (i.e., conversion of existing polishing basin), installation of a
new second clarifier and improvement to operations building.
Since the last inspection of 4/11/2019, the system has been issued violations for the following
exceedances; five for ammonia nitrogen (7/2020, 6/2021, 7/2021, 6/2023 & 7/2023); three for
coliform (9/2020, 10/2020 &4/2021); two for fecal coliform (9/2021 & 7/2023); and, two for BOD
(8/2023 & 9/2023). Based on the presence of foam or algae in the aeration pond as well as the two
ponds and the permit exceedances mentioned above, steps should be taken to remove and prevent
the buildup of foam and/or algae in the structures.
The operators were knowledgeable of the facility and their assistance during the inspection was
appreciated. Records were reviewed and found to be detailed, well organized and complete. The
facility is generally compliant with the terms and conditions of the permit. Please review the comment
sections of the inspection report for more details.

Permit: NCO021881 Owner-Facility: Lake Waccamaw WWTP
Inspection Date: 03/06/2024 Inspection Type: Compliance Evaluation
Influent Sampling Yes No NA NE
Comment: The current permit requires weekly composite samples of the influent for BOD and
TSS. The composite sampler was inspected and found to draw water from the existing
headworks, after the manual bar screen and grit chamber. The tubing needed to be
replaced and a dedicated thermometer was needed within the sample storage area.
An insect nest (likely a bee nest)was also located adjacent to the influent composite
sampler and this nest needs to be removed to prevent worker injury.
Equalization Basins Yes No NA NE
Is the basin aerated? 0 ❑ ❑ ❑
Is the basin free of bypass lines or structures to the natural environment? 0 ❑ ❑ ❑
Is the basin free of excessive grease? 0 ❑ ❑ ❑

Are all pumps operable? ❑ ❑ ■ ❑
Are float controls operable? ❑ ❑ 0 ❑
Are audible and visual alarms operable? ❑ ❑ 0 ❑
# Is basin size/volume adequate? ❑ ❑ ❑
Comment: The WWTP has a shotcrete lined aeration basin with 2 floating aerators that gravity
drain to the clarifier. Solids were recovered from the basin in August/September 2023.
The basin is not equipped with high level alarms. Foam covered a large area within
the basin, except where there was direct contact with liquid being recirculated by the
aerators; however, the foam was mostly contained in the basin and only a small
amount had entered the clarifier. The foam is believed to be associated with the
presence of older sludge, meaning that wasting of sludge from the basin might be
recommended.

Is the lagoon free of short circuiting? 0 ❑ ❑ ❑
Comment: Flow from the clarifier enters holding basin and then travels into an aerated polishing
basin, set up in series. Both basins have sheet piling installed a few feet from the
perimeters, but each have earthen sidewalls and bottoms. A relatively thin laver of
foam covered almost the entire surface of each of the basins; however, foam was not
present in any of the downgradient structures (manholes, Cl contact or dechlorination
chambers) nor at the eventual outfall.
