NPDES Permit No. NC0050105
Cumberland County .
Dear Mr. Noland:
Enclosed you will find a copy of the Compliance Biomonitoring Inspection report for the
inspection conducted the week of May :15, 2006: The inspection included the same objectives as
tliat of a routine Compliance Evaluation Inspection 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. Alt observations and recommendations are in Part
D. Summary of Findings/Comments of this inspection report. A whole effluent sample was
collected at Outfall 001 from the 24-hour composite of May 16 and May.; 19 for use -in a chronic
Ceriodaphnia dubia pass/fail toxicity test. This .sample was sent to the "Division of Water Quality
(AT) Laboratory, (located on Reedy Creek Road in Raleigh). The Whole Effluent Toxicity pass/fail
test results using these samples resulted in a "Pass". Test results for these samples indicate that the
effluent would not be predicted to have water quality impacts on receiving water. The plant effluent
composite sample that was taken by DWQ-FRO at the Rockfish WRF Outfall 001 on May 16 were
analyzed by the Division of Water Quality Chemistry Laboratory, located on Reedy Creek Road in
Raleigh, for the following parameters (which are currently in your NPDES Permit): Total Suspended
Solids (TSS) = <5 mg/L, Ammonia Nitrogen =.0.15 mg/L, Total Kjeldahl-Nitrogen (TKN) = 1.6
mg/L, Nitrates + Nitrites. as Nitrogen = 13 mg/L, and Total Phosphorus = 2.6 mg/L.

The temperatures of the effluent composite refrigerator were not recorded adequately (please
refer to the checklist in the "Effluent Sampling" section for more details). In addition, some of the
temperatures exceeded the range of 1.0 to 4.4 degrees Celsius. Requirements --- please take
appropriate corrective actions concerning the inadequacies of the following:
#1) record the temperature of the effluent composite refrigerator each time that a
composite sample is collected,
#2) the acceptable temperature range of 1.0 to 4.4 degrees Celsius must not be
exceeded. As a temporary measure, please place the composite sample container in an
ice bath inside of the sample refrigerator during collection, until the refrigerator can be
repaired or replaced.
Please respond to this office by July 21, 2006 concerning the two above -mentioned requirements.
Based upon the overall tour of the wastewater treatment plant, record keeping, self-
monitoring/reporting, and maintenance, this facility appears to be well maintained. DWQ-FRO
appreciates the time and professional courtesy that was extended by your staff during the inspection.
If you have any questions or comments concerning this report, please contact me at [phone].

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
At the time of this inspection, a screw pump was being used as a RAS pump. There appeared to be
excessive foam on the surface of the aeration ditches. Routinely, there was chlorine going in at the clarifier
weirs for algae control. The third clarifier had been offline for approximately. three to four months; it is in
working order. There was a large amount of duckweed in this clarifier. The temperatures of the effluent
composite refrigerator were not. being recorded adequately (please refer to the checklist "Effluent Sampling"
for more details). In addition, some of the temperatures exceeded the range of 1.0 to 4.4 degrees Celsius.
Please take appropriate corrective actions concerning the inadequacies of the recording of temperatures at
the effluent composite refrigerator and the acceptable temperature range.

Effluent Sampling
Comment: Some of the temperature readings that were recorded atthe effluent
composite refrigeratorexceeded.4.4 degrees Celsius. In addition, there were not
sufficient readings that were recorded for the days in which samples were taken. For
example, the ledger for 2006 showed that January had 15 readings for refrigerator
temperature, February had 14, March had 17, and April had 16 readings. This facility is
required to collect composites fivedays per week. It follows that there should beat
least 20 days per month that the temperature for the effluent composite refrigerator was
recorded on the temperature ledger for the effluent composite refrigerator.

Corrective Action
Rockfish Creek WRF, PWC
Permit No. NC0050105
This letter is a follow up to the report you filed after completing the Compliance Biomonitoring
Inspection of the Rockfish Creek WRF. In your summary you noted two inadequacies relating to
the effluent composite refrigerated sampler. You found that there were dates that samples were
collected . biit;'the refrigerator temperature was not logged. You also found that there were
refrigerator, temperatures recorded that exceeded the acceptable. temperature range of 1.0 to 4.4
degrees Celsius.
I have used this report with staff to .reinforce the =requiremerits%‘:of sreVoiding the refrigerator
temperature each time a sample is collected • and the acceptable temperature range: The usual
practice was to record the temperature on an Equipment Operation Temperature Record form
attached to the sampler. I have now added an entry space for -this data on the daily sample
collection Chain of Custody to help ensure this requirement is met. Operations personnel have
also been made aware. that they can manually adjust the temperature setting for the refrigerator. If
that doesn't help maintain the acceptable temperature range they can utilize our work order
system and have maintenance personnel investigate the problem. I would like to also note that
maintenance personnel have checked the refrigerated sampler and found it to be functioning
properly.
The Rockfish Creek WRF has always worked to maintain compliance and hopes that our
corrective action taken in relation to the areas noted in your report will be found sufficient. If you
have any further concerns or questions please contact me at [phone].
