The problem occurred while maintenance was being performed on one of two banks on the U.V. system.
A mechanic locked out the ballasts and bulbs on one bank of the U.V. system, leaving the other bank on­
line. With the bulbs retracted, the wipers began to extend. In this position the bulbs and sleeves would be
pushed into the walkway and potentially cause injury or damage to eguipment. The mechanic
immediately began pulling relays from the power panel to stop the wiper movement. One of the relays
the mechanic pulled was improperly replaced and caused the U.V system to go into low level alarm
condition. The unit is designed not to operate in low level alarm condition. It took approximately an hour
to diagnose the problem and return the unit to operation.

The relay was put back in the right location and the U.V. system was returned to normal operation. While
the U.V. system was off, operations staff began filling an empty clarifier to minimize water flow to the
U.V. system and effluent channel. The U.V. outfall gate was closed to allow the reuse system to operate
from the reclaim storage tank.
The Operator SOP book was updated with additional procedures, giving specific measures to take when
and if the U.V. system fails in the future. The manufacturing representative for the U.V. system was
contacted by maintenance staff to get a complete understanding of the wiper system and to ensure that it
stays off during future maintenance events. A statement was added in the computerized maintenance
monitoring system to ensure the wiper system is deactivated before any maintenance work is performed
on either U.V. bank.

In response to this situation the third BNR train was put on line, a 4th clarifier was put on line and chemical feeds were
turned up to help the process. The UV outfall gate was closed to the reclaim system and the storage tank is being used
for source water.

Subject: RE: 5 Day WWTP Bypass Report
Process control testing was done at 2100 on 1/10/14 and the NH3 , NO3 and PO4 numbers were in normal ranges and
INF and EFF pH values on SCADA were in normal ranges. The next set of process control samples was completed around
0200 on 1/11/14 and the NH3 numbers were unusually high in the plant. This trend continued until 1400 today and the
NH3 numbers are starting to return to normal parameters.
It appears that either a slug of ammonia or something impacting the nitrification process passed through the plant
possibly related to the high pH event of 1/10/14. We have done everything we can do at the plant maximize treatment
and will closely monitor the plant with process control testing over the rest of the weekend.

I wanted to update you on the high influent pH event at the Triangle WWTP that we reported to you on 1/10/14. To
recap, at 1410 on 1/10/14 the plant SCADA system gave us a high pH alarm of 8.5 and the number increased to 8.9 and
then went back out of alarm at 1451. Multiple pH samples were collected by lab staff and the highest recorded pH
number was 8.4.
I have attached the newest 5-day report dated 2009, you can use this form going forward.
Thank you again,
Autumn

The attached spreadsheet shows the Triangle WWTP in Durham County is currently at 91.60% capacity.
We know that a plan should be in place to address capacity issues, once 90% capacity is met.
To that end, please note the attached letter from the Town of Cary, indicating their timeline for discontinuing their
discharge to the Triangle WWTP.
This plan shows that over the next few months, our flow will be reduced by ~40%, and our capacity issue will be
resolved.

The lab, Meritech, had some of the June 11, 2014 sample stored and reran the analysis. The new analysis indicates a
much lower TN at 3.03 mg/l which is a reasonable value based on my knowledge of wastewater treatment and our
facility. Attached is a copy of the revised lab report and an updated spreadsheet. We will ask Meritech for an
explanatory letter, and based on their letter may report the revised value on our DMR with an explanatory note.
Thank you for your persistent process control efforts and proactive approach©
Sincerely,
Autumn

Subject: RE: Wastewater Lab Data Anomaly
The Triangle Wastewater Treatment Plant lab data for June 11, 2014 for Total Nitrogen shows an atypical concentration
of TN (7.63 mg/l). Our Ammonia data from the same time period is <0.01 mg/l, but the TKN is 5.17 mg/l. This would
indicate a Organic Nitrogen concentration close to 5.17 mg/l. Our average Organic Nitrogen for the previous twelve
months is 0.66 mg/l (excluding the 5.17 mg/l outlier). A nitrogen species evaluation spreadsheet is attached. (Please
note the ammonia values is the average from the day before and the day after the sampling event). We have asked the
laboratory, Meritech, to review their labwork.
We have reviewed our operator logs and process information, and have not found any potential TWWTP cause for a
high Organic Nitrogen concentration. We are also unaware of any industrial discharge change which could explain this
value. Last week, we pulled two sets of samples for TN to determine if the problem is recurring.
I do not believe this one data point is an exceedance of a permit limitation; however, recurrence could present a
problem with our compliance with our annual nitrogen load. We will continue to monitor the situation closely. I will
include a note about this datapoint in the DMR.

Subject: August 6, 2014 toxicity split test review results
Mr. Pearce,
Pat McCrory
Governor
A review of sampling, testing, and laboratory' documents and procedures was completed to
investigate the difference in test results. This review showed no obvious cause for the disagreeing
results. We did learn, however, during a telephone conversation with Stephanie Brixey of Durham
County Triangle WWTP, that facility staff perform the splitting of the composite sample by mixing
the sample and then filling the first laboratory sample bottle completely before mixing the sample
again and filling the next laboratory sample bottle.
The test result from Meritech. Inc. will stand as the official result and a result of “pass” has been
recorded for the August 6, 2014 Durham County Triangle WWTP toxicity test. If you have any
questions regarding this split test review please contact us at 919-743-8401.

This letter is in reference to the Durham County Triangle WWTP whole effluent toxicity split test
dated August 6, 2014. Chronic Ceriodaphnia dubia pass/fail split testing was performed by
Meritech, Inc. and Pace Analytical Services. The test completed by Meritech, Inc. passed and the
test completed by Pace Analytical failed.
For toxicity testing we highly recommend the following procedure be used to ensure that a
thoroughly mixed and evenly portioned sample is obtained. First, mix the composite sample and
rinse each of the sampling containers. Then, mix the composite sample again and fill the first
sample bottle ‘A full. Next, mix the composite sample again and fill the second sample bottle ‘A full.
Repeat this mixing and pouring in % increments, while alternating between the two sample bottles,
until both sample bottles are filled leaving minimal headspace.

Autumn,
On Monday, the Town of Cary transferred the flow from their Morris Branch pump station away from the Triangle
WWTP. Due to the lower flow and load, we removed one of three trains from service. Based on process data, it
appears the plant is running well on two trains.
"Knock on wood",
Joe
