The discharge from the Troy wastewater treatment facility flows to Densons
Creek (7Q10 of 0.35 cfs flow, as according to the Whole Effluent Toxicity
Testing Self -Monitoring Summary --- see attachment), classified as Class C
waters --- which promotes aquatic life propagation and survival, fishing, wildlife,
secondary recreation, and agriculture. Densons Creek flows into Little River,
and on to the Pee Dee River.
PART II - DISCRIPTION OF WASTES AND TREATMENT WORKS
Volume of wastewater to be permitted:
(Ultimate Design Capacity)
What is the current permitted capacity of the Wastewater Treatment facility?
1.2 MGD
1.2 MGD
Actual treatment capacity of the current facility (current design capacity)?
1.2 MGD
Please provide a description of the existing or substantially constructed
wastewater treatment facility:
Flow enters the headworks of the plant. If the flow is greater than 1.2 MGD, the
excess flow is diverted to a 10-acre lagoon (EQ Basin) and it is later sent back
into the WWTP for treatment. The untreated wastewater noinially flows through
a "low flow" type mechanical bar screen, then to an aerated grit chamber and grit
removal system. The material removed is disposed at the Uharrie Landfill as
needed. An influent Parshall Flume with an ultrasonic flow meter then meters
flow. Flow then travels to the two oxidation ditches arranged series rather than
parallel, then to two secondary clarifiers. The clarifier effluent flows to through
UV disinfection light bank, then to Densons Creek.. All Waste Activated Sludge
solids that are removed from the plant enter a sludge transfer tank, then into an
aerobic digester, and on to land application by Synagrow.
e. Possible toxic impacts to the surface waters:
None

2. Residuals handling and utilizing/disposal scheme:
a. If residuals are being land applied, please specify the DWQ Permit No.

transfer tank, then into an aerobic digester, and on to land application by
Synagrow.
3. Treatment plant classification (attach completed rating sheet):
Grade III (see attachment)
4. Alternative Analysis Evaluation: Has the facility evaluated all of the non -discharge
options available: Please provide the regional perspective for each of the options that
were evaluated.
Connection to Regional Sewer System:

PART IV — EVALUATION AND RECOMMENDATIONS
1. The applicant is not requesting modification of the facility or increasing flow at this time.
2. A review of the compliance data did not reveal any significant violations.
3. Based upon the previous Compliance Evaluation Inspection (CEI) that was conducted on
January 13, 2009, all units were in service, and "this facility continues to maintain a high
standard for wastewater treatment".
4. This Office recommends continuation the Special Conditions for Whole Effluent Toxicity
monitoring and Pretreatment Programs.
5. Based upon the above information, this Office recommends reissuance of the said peiinit
for the continued operation of an existing 1.2 MGD wastewater treatment facility
consisting of flow equalization, mechanical bar screen, grit removal, Parshall Flume, dual
oxidation ditches, dual secondary clarifiers, aerobic sludge digester transfer tank and
aerobic digester, UV disinfection, chlorination/dechlorination (back-up) located at the
Town of Troy's wastewater treatment plant on Glenn Road, northeast of Troy in
Montgomery County.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The ORC set up and calibrated the flow proportional sampling for the 24-hour effluent composite sampler.
The ORC performed the annual calibration check of the influent ultrasonic flow meter. An operator
routinely visited the POTW every day of the week (7 days/week). Donna Mills was the Back -Up ORC for
this POTW. The SCATA system phoned the ORC first, then proceeded to other operators until someone
answered the call and the problem at the POTW, such as: #1 was the high level sludge alarm, #2 was the
high temperature alarm for the influent pumps, #3 was the overtorque alarm for the grit classifier, and #4
was the alarm for the UV unit power. As a reminder and to ensure compliance with this part of the permit,
please review the NPD,ES Permit, Part II, Section A, Composite Sample, concerning each grab sample in
the composite not being less than 100 mL in volume, and "the preset gallon interval between sample
collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system" for Variable
time/constant volume.

(If units are separated) Does the chart recorder match the flow meter?
Comment:
Effluent Pipe
Is right of way to the outfall properly maintained?

If effluent (diffuser pipes are required) are they operating properly?
Comment:
Drying Beds
Is there adequate drying bed space?
Is the sludge distribution on drying beds appropriate?
Are the drying beds free of vegetation?
# Is the site free of dry sludge remaining in beds?
Is the site free of stockpiled sludge?
Is the filtrate from sludge drying beds returned to the front of the plant?

Owner - Facility: Troy WWTP
Inspection Type: Compliance Evaluation
Bar Screens
Is the screen free of excessive debris?
Is disposal of screening in compliance?
Is the unit in good condition?
Comment: The flow through the manual bar screen (with approximately 1 to 2 inch
openings) was in series with the mechanical bar screen (installed approximately two
years ago). The manual bar screen does not allow large material to pass through to
the mechanical bar screen (a stainsless steel "low -flow screen" that was manufactured
by Jones & Atwood). Screening went to the Uharrie Landfill.
Grit Removal
Type of grit removal
a.Manual
b.Mechanical
Is the grit free of excessive organic matter?
Is the grit free of excessive odor?
# Is disposal of grit in compliance?
Comment:. The grit removal equipment used a chamber that was -periodically aerated,
then an air lift pump carried the grit up a pipe to the grit classifier for dewatering, then to
a dumpster and to the Uharrie Landfill.
Equalization Basins
Is the basin aerated?
Is the basin free of bypass lines or structures to the natural environment?
Is the basin free of excessive grease?
Are all pumps present?
Are all pumps operable?
Are float controls operable?
Are audible and visual alarms operable?
# Is basin size/volume adequate?
Comment: When the influent exceeded 1.2 MGD, then flow entered the ten -acre EQ
(lagoon) by excessive flow through a valve -less pipe from the influent wet well. Each of
the two influent pumps were capable of handling 1.2 MGD of flow.. They alternated
each time that they came on. The flow to the EQ was later fed back into the WWTP
for treatment.

Is the DO level acceptable?(1.0 to 3.0 mg/I)
Are settelometer results acceptable?(400 to 800 ml/I in 30 minutes)
Comment: In addition, there were two horizonal mixers in the oxication ditches. The
target MLTSS was 3,500: mg/L. The two oxidation ditches were operated in series,
rather than in parallel.
Disinfection - UV
Are extra UV bulbs available on site?
Are UV bulbs clean?
Is UV intensity adequate?
Is transmittance at or above designed level?
Is there a backup system on site?

Is the generator tested under load?
Was generator tested & operational during the inspection?
Do the generator(s)have adequate capacity to operate the entire wastewater site?
Is there an emergency agreement with a fuel vendor for extended run on back-up power?
Is the generator fuel level monitored?
Comment: , No automatic switchover, only a manually operated generator. The
generator was tested under load approximately twice per year.

Classification of Biological Water Pollution Control Treatment Systems:
Grade I Biological WPCS
- Septic tank/sand filter systems.
- Biological lagoon systems
- Constructed wetlands and associated appurtenances
Grade II Biological WPCS
- Systems that utilize an activated sludge or fixed growth process with a peiniitted flow
less than or equal to 0.5 million gallons per day (mgd)
Grade III Biological WPCS
- Systems that,utili7e an activated sludge or fixed growth process with a permitted flow
of greater than 0.5 through 2.5 million gallons per day (mgd)
- Grade II systems that are required to achieve biological nutrient reduction
Grade IV Biological WPCS
- Systems that utilizing an activated sludge or fixed growth process with a permitted flow
of greater than 2.5 Million gallons per day (mgd)
- Grade III systems. that are required to achieve biological nutrient reduction *
* Biological Nutrient Reduction -
The reduction of total nitrogen or total phosphorous by an activated sludge or fixed growth
process as required by the facilities permit.

Classification of Collection Water Pollution Control Systems:
(whichever provides lowest grade)
Same grade as biological water pollution control system. Grade of system:
Based on population served:
1,500. or Less = Grade I
1,501 to 15,000 = Grade II
15,001 to 50,000 = Grade III
