PART IV - EVALUATION AND RECOMMENDATIONS
The permittee is requesting that the existing permit for the subject facility be renewed.
The facility was well operated and maintained on the day of the site inspection. Significant
stormwater flows associated with infiltration and inflow have been identified within the facility's
collection system. During the previous 12 months, the average wastewater flow to the plant has
approached 70% of the permitted capacity. During the previous 4 months, the average
wastewater flow to the plant has exceeded 90%of the permitted capacity. The permittee is in the
process of securing funds for repairs to the collection system to reduce the flow associated with
I&I.
The permittee also indicated that the existing ultrasonic flow meter appears to be
reporting flows approximately 0.10 MGD above the actual flow. The parshall flume is located
within five feet downstream of a 90 degree bend in the wastewater influent channel. During the
inspection whirlpools were observed in the immediate vicinity of the parshall flume. Based on
these observations, it appears that the ultrasonic flow measurements are elevated but to what
extent remains to be determined. If flow continues to be recorded at the present levels, the
mechanism for monitoring flow through the plant may need to be altered,
It is recommended that the permit be renewed as requested.

Permit Notes
NC0021628
The Town of Norwood is requesting renewal of existing permit for its wastewater
treatment facility. The facility discharges to the Rocky River and the stream
classification is C. The segment of the Rocky River that Norwood discharges to is
not listed on the 1998 303(d) list. However, there is a segment upstream of Norwood
that is rated as nonsupporting for nonpoint pollution - from source to SR2420,
Mecklenburg Co. The problem parameters are fecal coliform, turbidity, and sediment.
The receiving stream is 80 to 120 feet wide, however the depth of the river could not be
determined because of its muddy red color. The plant has a design capacity of 0.750
MGD. MRO staff report states that permittee submitted a Preliminary Engineering
Report (PER) proposing several upgrades to the plant including an additional aerobic
digester, rehabbing the existing clarifiers, reconfiguring the influent flow meter, chlorine
contact basin, and addition of sludge drying beds.
Current limits for the design capacity of 0.750 MGD are:
BOD5 30 mg/I
NH3 monitor
TSS 30 mg/l
Fecal 200/I00ml
Chlorine monitor
Monthly monitoring for copper, lead, and zinc.
Chronic toxicity test @ 2.7 % in March, June, September,
and December.
Compliance Data Review
Qw average —0.554 MGD from 12/98 — 11/99.
Qw average —0.538 MGD from 12/97 — 1 1/98.
Qw average — 0.5045 MGD from 12/96— 11/97.
One TSS violation in January 1999. One BOD5 violation in March 1998and one TSS
violation in June 1998.
Plant appears to be well operated. There were only three permit violations within the past
three years. All other limitations are being consistently met. The facility's average flow
for the past three years is 0.532 MGD, which is below the design flow of 0.750 MGD.
Based on these flows. the Norwood WWTP is at nearly 71% of capacity.
Per conversation with Tom Poe of Pretreatment. Norwood has an inactive pretreatment
program.

r
Chronic Toxicity Results
Facility has a quarterly Chronic Toxicity Test @ 2.7%. Since 1995, facility has passed
all toxicity tests. One bad test in June 1999, followed by a PASS in September 1999.
Appears to have no problem meeting the toxicity limit.
Instream Monitoring Data
There is no recommended instream monitoring for this facility because of the size
of the receiving stream and amount of dilution.
Reasonable Potential Analysis (RPA) Results
Norwood currently has monthly monitoring for copper, zinc, and lead in its
permit. Results of the RPA indicate that none of these parameters shows a potential to
exceed the instream standards based on the concentrations being discharged. Data from
the past three years were analyzed and none of the predicted concentrations for the
parameters exceeded the allowable concentrations. Based on this information,
recommend the deletion of monitoring for copper, zinc, and lead.
2/25/2000— Conversation with Dana Folley of Pretreatment—we reviewed
facility's application and saw that they listed receiving industrial wastewater from three
dischargers. No additional effluent information was attached however the application did
indicate that the following substances were in the discharge: NH3, cadmium (TCLP
sludge data), chromium (TCLP sludge data), lead, copper, and zinc. Dana said that the
presence of Cd and Cr in the sludge does not necessarily indicate presence in the effluent.
Because of the size of the receiving stream, more than likely none would be found.
Indicated that she wanted additional info on the three industrial discharges and had talked
with John Leslie in the MRO who was going to contact the Town. She said we should
not change the permit recommendation on Cu, Zn, and Pb. Would look at data after
talking to MRO, she may added parameters to the pretreatment permits if any are ever
assigned. Norwood is currently inactive but they may have to be revised.
Recommend renewal of NPDES permit for 0.750 MGD and most of its
existing limits, with the deletion of monthly monitoring for copper, zinc, and lead.
