Compliance Inspection Report
Troy WWTP
NPDES WW Permit No. NCO028916
Montgomery County
Dear Mr. Brantley:
WOPOS
FA'IETTE-in, i OFFIC,=
We appreciate this opportunity to provide clarifidation as to why the damage inflicted on the Town wastewater
treatment plant (WWTP) equalization (EQ) basin by Hurricane Florence on September 181, 2018, has not been fully
resolved and a status update on the Town's interim and permanent repair efforts.
On or about September 26, 2018, the Town placed a row of sandbags across the invert area of the breach as an interim
breach closure/abatement measure. Those sandbags have remained in place since that time.
A permanent repair of the damage has been a matter of continual effort on the part of the Town in conjunction with
FEMA and NC DPS Emergency Management from the time a claim for the damage was submitted to FEMA after
Montgomery County was included as part of the Hurricane Florence National Disaster declaration area. The Town is
currently awaiting a response from FEMA on a revised damage repair design concept and opinion of cost which was
submitted to FEMA by the Town last month. The Town has already submitted a request to FEMA so that once a
damage repair design approach and estimate is mutually agreed upon by FEMA and the Town, those funds can be
allocated to the Town for use on an Alternate Project under Section 428. Under the Section 428 program, the Town
will then submit a plan to FEMA for restoration of the EQ basin as a mitigation project.
The actual project being planned for implementation, which will be presented to your office for approval once the
funding arrangements are fmalized with FEMA, will consist of the construction of a berm -enclosed area located in
the northwest area of the existing EQ basin. The berm will impound approximately 2.3 acres of area and provide an
initial EQ basin volume of approxir-iately 1 million gallons. The remaining portion of the existing EQ basin,
comprising approximately 11 acres, will be abandoned in accordance with NCDWR guidelines. The estimated cost
for construction of the replacement, reduced -size EQ basin is approximately $0.5 million.
The anticipated timeline for completion will be totally dependent on access to FEMA funds and the FEMA process,
but the current expectation is that funding arrangements should be completed by end of the year. Design and
permitting is anticipated to require 3 months and construction possibly 4 to 5 months. We will do everything in our
power to compress this timeline as much as is possible while remaining in compliance with FEMA requirements.
Please let us know if you have any questions.
Sincerely,
Greg Zephir

Dear Permittee:
The North Carolina Division of Water Resources conducted an inspection of the Troy.WWTP on
9/17/2019. .This inspection was conducted to verify that the facility is operating in compliance.with the
conditions and limitations specified in NPDES WW Permit No. NC0028916. The findings and comments
noted during this inspection are provided in the enclosed copy of the inspection report entitled
"Compliance Inspection Report". -
Please respond in writing to this office within 30 daysof your receipt of this letter regarding your plans

On September 17, 2018 the dam on the equalization basin was breached due to heavy rains and flooding from
Hurricane Florence. Since then, the Town of Troy has been in contact with their engineering firm on how to
repair this structure. However, during periods of high flows, wastewater is still allowed to enter the
equalization basin. This wastewater has the potential to discharge through the breach into Spencer Creek,
which runs behind the equalization basin. This discharge of wastewater would be considered a by-pass of the
wastewater treatment system. The Town of Troy could then be assessed a civil .penalty for an unpermitted
and illegal discharge of wastewater to Waters of the State.
The Fayetteville Regional Office suggests that the town permanently or temporarily fix the breach in the
equalization basin to prevent an unpermitted discharge of wastewater that entered the basin from the
collection system or stormwater mixing with residuals (then stormwater becomes wastewater). If the town
valves off the line leading to the equalization basin then, during high flows, wastewater will then exit the
collection system at the lowest spot and that bypass/SSO would need to be reported to the regional office, as
required, by the facility's NPDES permit or the Town's Collection System permit.
Please have a structural evaluation performed on the Equalization Basin by a North Carolina Licensed
Professional Engineer to ensure the integrity of this treatment unit.
Comments
*Need to move the bisulfite drip to a location upstream of the effluent sampling location: As a reminder
the effluent sample should be taken after all treatment.
*The June 2019 eDMR was compared to laboratory bench sheet. Please correct the data in the
temperature column and on June 26, 2019 the BOD result was reported as >2 mg/I but the laboratory
sheet reported*the BOD as <2 mg/I. Please the correct the errors on the eDMR and submit a revised
copy.
If you should have any questions, please do not hesitate to contact Mark Brantley with the Water
Quality Regional Operations Section in the Fayetteville Regional Office at 910-433-3300 or via email at
