Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Lauren Armeni, Dan Boss, Melanie Kemp, and Mara Chamlee, with the Asheville Regional Office,
conducted a Compliance Evaluation Inspection of Waynesville WWTP on April 10, 2023. This
inspection was conducted to determine whether the facility is being operated and maintained in
compliance with NPDES Permit No. NC0025321. Mr. Jeff Evans (ORC) was present and assisted in
the inspection.
On December 31, 2020, the Environmental Management Commission entered into the subject
Special Order by Consent (SOC) whereby Waynesville WWTP was granted relaxed effluent limitations
from those imposed by the NPDES Permit, in exchange for Waynesville’s commitment to a schedule
of wastewater treatment plant improvements that will return the WWTP to compliance with the terms
of the NPDES Permit. As of the April 2023 SOC Quarterly Report, the construction road was complete
and Harper Construction is on-site starting construction of the Headworks of the plant.
The following items/upgrades were noted during the inspection:
Operations & Maintenance: Overall, the plant is unable to maintain adequate solids handling due to
increased flow to the WWTP from I&I and outdated infrastructure, which causes chronic exceedances
of TSS and BOD.
Flow Measurement - Influent: The facility cannot accurately measure flows above 6 MGD. Per the
Authorization to Construct (ATC) for the plant upgrades, a new influent Parshall flume will be installed.
Mr. Evans indicated that a new influent flow meter will also be installed that can interface with the
effluent composite sampler.
Bar Screens: Screenings from the bar screen go directly into a wheelbarrow and are then dumped
into a skid steer and placed into a dumpster once a week. Per the ATC for the plant upgrades, two
mechanical bar screens (each rated for 15 MGD at peak hourly flow) and one manual bar screen will
be installed. The new mechanical bar screens will have an auger that dewaters the screenings.
Grit Removal: Per the ATC for the plant upgrades, a new vortex grit removal unit rated for 15 MGD at
peak hourly flow will be installed.
Primary Clarifier: At the time of the inspection, scum removal in the south primary clarifier did not
appear adequate due to excessive scum and grease floating in the scum trough. Mr. Evans indicated
this issue is from excessive rain which causes the lines to get clogged. There are two sludge pits, one
for each clarifier, that are pumped out by a septage hauler and dumped into the grit chamber. There
is also one scum pit in the center of the sludge pits that is pumped out and into the grit chamber. Per
the ATC for the plant upgrades, three primary disc filter units each rated for 7.5 MGD at peak hourly
flow will be installed and the primary clarifiers will eventually be taken offline.
Aeration Basins: Per the ATC for the plant upgrades, the aeration basins will be rehabilitated which
includes the replacement of the existing diffusers with new fine bubble disc diffuser grids and the
construction of four 2,330 SCFM rotary screw blowers.
Secondary Clarifier: The secondary clarifiers are in the same state as previous inspections. The
clarifiers are rectangular and undersized, and scum removal of the trac-vac system has not been in
operation for awhile. There is still inadequate detention time due to the clarifiers not being deep
enough, which doesn't allow solids to adequately settle out, and therefore a significant amount of
solids are carried through to the chlorine contact chamber. Per the ATC for the plant upgrades, the
secondary clarifiers will be rehabilitated which includes raising the walls by 4' to get 12-foot side water
depth, and installing a new chain and flight rake system for solids removal as well as new effluent
weirs.

Compliance Evaluation
Disinfection - Gas: Heavy flows continue to cause excessive solids to discharge from the chlorine
contact chamber and into the effluent, which creates a significant chlorine demand. Per the ATC for
the plant upgrades, the existing gas chlorination will be converted to a liquid chlorination disinfection
system, including construction of two 4,000-gallon sodium hypochlorite storage tanks.
De-chlorination: Per the ATC for the plant upgrades, the existing gas dechlorination will be converted
to a liquid de-chlorination system, including construction of two 500-gallon sodium bisulfite storage
tanks. Following de-chlorination, the effluent is reaerated via cascades prior to discharge.
Solids Handling Equipment: Sludge from the primary clarifiers is pumped to the primary thickener.
Sludge from the secondary clarifiers is pumped to the secondary thickener. The sludge is thickened
before entering the digester and the first aeration basin. Mr. Evans indicated that as long as the belt
press is running it is not necessary to pump sludge into the first aeration basin. Per the ATC for the
plant upgrades, the belt filter press will be rehabilitated, specifically everything will be replaced except
for the frame.
Aerobic Digester: At the time of the inspection, the sludge holding tank was not aerated, and
therefore is not functioning as intended. Per the ATC for the plant upgrades, the previous anaerobic
digester will be converted to an aerated sludge storage tank, which will include the installation of a
membrane tube diffused aeration system, one rotary lobe blower, and all necessary piping and
controls. The conversion has begun, but the aeration system has not been installed yet.
Effluent Sampling: At the time of the inspection, effluent composite sampling was not flow-proportional
and hasn't been for awhile because the influent flow meter does not interface with the composite
sampler. As previously mentioned, a new influent flow meter will be installed that can interface with
the effluent composite sampler.
Standby Power: The current generator cannot power the entire plant during an outage. Per the ATC
for the plant upgrades, two 600 kW backup generators will be installed that will be able to power the
entire plant during an outage.
The following violations were noted during the inspection:
1. Flow Measurement - Influent: The facility cannot accurately measure flows above 6 MGD.
2. Primary Clarifier: The scum removal from the primary clarifiers is inadequate.
3. Secondary Clarifiers: Scum removal of the trac-vac system is not in operation and retention time is
inadequate, leading to the discharge of high levels of solids.
4. Disinfection - Gas: The chlorine contact chamber has excessive solids.
5. Effluent Sampling: Effluent composite sampling is not flow-proportional.
6. Aerobic Digester: The current sludge holding tank is not being aerated.
7. Standby Power: The generator cannot power the bar screen or blowers during a power outage,
and therefore the wastewater cannot be adequately treated during such an event.
