Dear Mr. Cummings:
ATA 4:1
NCDENR
Enclosed you will find a copy of the Compliance Biomonitoring Inspection report for the
inspection conducted the week of February 5, 2001. The inspection included the same objectives as that
of a routine Compliance Evaluation Inspection (conducted on February 6, 2001) plus an Aquatic Toxicity
(AT) test to evaluate the biological effect of the facility's discharge on test organisms. As part of the
inspection a tour of the Wastewater Treatment Plant was conducted. All observations and
recommendations are in Part D: Summary of Findings/Comments of this inspection report. A 24-hour
effluent composite sample at Outfall 001 was collected on February 6 and February 9 by Dale Lopez and
Don Register of the Division of Water Quality for use in a chronic Ceriodaphnia dubia pass/fail toxicity
test. The aquatic toxicity analysis was completed by the Division of Water Quality Aquatic Toxicology
Laboratory, located on Reedy Creek Road in Raleigh. The pass/fail toxicity test, using these samples,
resulted in a Pass, indicating that the effluent would not be predicted to have water quality impacts on the
receiving waters. Additionally, on February 6, 2001, the above mentioned 24-hour Outfall 001
composite was sampled for the .following parameters: Biochemical Oxygen Demarid (BOD), Total
Suspended Solids (TSS), Ammonia as nitrogen, Total Kjeldahl Nitrogen, Nitrite plus Nitrate as nitrogen,
and Total Phosphorus. The results of these analyses will be forwarded to you when they are completed
by the Division of Water Quality Chemistry Laboratory, located on Reedy Creek Road in Raleigh.
If you have any questions or comments concerning this report or require clarification on part(s) of
this report, please feel free to contact me at 910/486-1541.

Pembroke Wastewater Treatment Plant (WWTP)
BIOMONITORING EVALUTATION INSPECTION
performed during the week of February 5, 2001
DESCRIPTION of Pembroke WWTP:
The 1.33 MGD wastewater treatment plant consists of a mechanical bar screen, grit removal, influent
pump station, dual oxidation ditches (one ditch is being used, 534,000 gallons capacity each), dual
clarification (both are being used, 206,000 gallons capacity each), chlorine contact chamber, de -
chlorination, cascade post -aeration, and sludge digestion.
SECTION D: SUMMARY OF FINDINGS/COMMENTS:
PLANT TOUR---
1. Measurements of the clarifier sludge blankets:
clarifier #
clarifier depth
sludge blanket depth
1
14 feet
7 feet
2
14 feet
9 feet
2. The Outfall 001 Discharger Monitoring Report (DMR) for October 2000, was cross-checked with the
laboratory bench sheets. There were 81 data points that were cross-checked for pH, residual
chlorine, Biochemical Oxygen Demand (BOD), ammonia nitrogen, Total Suspended Solids (TSS),
fecal coliform. All data were in agreement.
3. The grit pump was not operating in the automated mode, (needs mechanical repair).
4. The screenings, grit, and grease removal were hauled to the Robeson County Landfill.
5. The influent pump station has three pumps. VFD #2 was not operating, the drive unit has been out -
of service for the last six months.
6. One oxidation ditch was in operation. The dissolved oxygen was 0.8 to 1.0 mg/L. The most recent
Mixed Liquor Suspended Solids (MLSS) results were 4,000 mg/L.
7. Chlorine was flow paced and the sulfur dioxide was residual paced. The chlorine residual meter
readout was 0.4.
8. The effluent Outfall 001 was easily accessible.
9. CITI, LLC-Systems Integrator last calibrated the flow meter on February 28, 2000 ["Flow
measurement devices shall be accurately calibrated at a minimum of once per year": 15A NCAC 2B
.0505 (b)(1)].
10. Sludge is handled by Porter Environmental, permitted through Porter, to be land applied on land
owned by Porter, at a maximum of 100,000 gallons per month.
11. The aerobic sludge digester appeared to have a level over full.
12. The solids did not appear to be settling well. A 30-minute Settleability Test was performed on the
oxidation ditch's Mixed Liquor, and the solids remained in suspension (this indicates an old sludge
with a low F/M ratio).
13. Technical assistance is available at our office upon request.
14. Before the inspection, there was not a thermometer in the effluent compositor refrigerator. The
temperature of the effluent sample was routinely being recorded after it was received at the
laboratory, and the temperatures met the acceptable temperature rang' of 0 to 4. degrees Centigrade
(as according to the official storage temperature requirement published in 40 CFR Part 136.3(e),
Table II). During the inspection a thermometer was placed in the effluent compositor refrigerator,
and the temperature of the effluent compositor is now being recorded. It will be cross-checked
annually with an NIST certified thermometer.

15. The telescopic valve in the aerobic digester was under repair. As of Monday, February 12, it has
been repaired and put back into service for supernating..
LABORATORY TOUR---
1. Laboratory parameters that are analyzed on site: pH, Residual Chlorine, Biochemical Oxygen
Demand (BOD), Ammonia Nitrogen, Total Suspended Solids (TSS), Fecal Coliform, Dissolved
Oxygen, SOUR test, and temperature.
2. Mercury, Total Nitrogen, and Total Phosphorus are sent to Environmental Science Corporation in Mt.
Juliet, TN (NC Cert. #375).
3. Chronic Toxicity is analyzed by Meritech.
4. The pH buffer expiration dates are:
Buffer
Date
pH 4
10/01/01
pH 10
09/30/01
pH 7
11/30/01
5. The millivolts of the 7 pH buffer is 14.7 mV.
6. The pH, chlorine, and dissolved oxygen analyses are performed within fifteen minutes of collection.
7. TSS weights are measured on a Mettler AE 160. A 0.2 gram weight crosscheck is performed daily.
8. Laboratory temperatures:
Instrument
Temperature (degrees C)
BOD Incubator
21.0
Sample Refrigerator
0.5
TSS Drying Oven
105
Fecal Coliform
44.6
9. The pH meter is sloped with the pH 7 and pH 4 buffers. Afterwards, the 7 pH buffer is read. It
should read between 6.9 to 7.1 pH units.
10. An NIST crosscheck of all of the thermometers is performed and documented annually.

•
RECOMMENDATIONS---
1. Recommend that, in order to calculate the % error, the ultrasonic flowmeter calibration report for
the V-Notch Weir have the ultrasonic's reading before and after calibration, and the V-Notch
Weir's head measurement (in feet or meters at the ultrasonic flowmeter location). According to
15A NCAC 2B .0505 (b)(1): "Devices selected shall be capable of measuring flows with a
maximum deviation of less than 10 percent from true discharge volumes. Flow measurement
devices shall be accurately calibrated at a minimum of once per year and maintained to ensure
that the accuracy of the measurements is consistent with the accepted capability of that type of
device."
2. Considering that the VFD #2 has been out of service for over a year, and the apparent difficulty in
obtaining spare parts and repairs for the VFD pumps, it is suggested that the Town repair or
replace this pump immediately. Further, the Town should evaluate the feasibility of replacing
these pumps with equipment that can be repaired in a more timely manner.
