Proposed RCW Discharge Point
The proposed discharge point for the reclaimed water is shown on the attached map (NAD 83
coordinates: N 782,865.09 E 1,987,011.41). The reclaimed water would be released into a 10' x 10'
box culvert located near Skipper Bowles Drive, on UNC-Chapel Hill's main campus. The box culvert is
located on a un-named tributary to Meeting of the Waters Creek, which is a tributary to Morgan Creek.
The tributary watershed above the box culvert is an extensively urbanized portion of the main campus.
Reclaimed water released into this box culvert would eventually flow right past the discharge point for
our Mason Farm WWTP, where that same water would have been released if our reclaimed water
system was not in operation or demands were very low.
lets discuss when you get a chance
thanks!

I am writing to request your written approval for OWASA to temporarily release to surface waters a
limited amount of reclaimed water for a limited time period in order for us to complete our performance
and operational testing for our new reclaimed water system. Information relating to this request is
provided below.
Proposed Rate and Time Period of Discharge
We request approval to discharge reclaimed water at this point in an amount up to 1,500 gpm for a
maximum of 8 hours a day for up to five days.

Danny:
This approval should come from you guys.
I have no problem with it. There does seem to be a lot of water released....! calculate a maximum of 720,000 GPD for
five days. If it is truly treated to reuse standards, then it should not be a problem. The limits at Mason Farm
WWTP are really tight in the summer: 4 mg/L BOD and 2.0 mg/L ammonia.

Purpose for Request
We have completed construction of our new reclaimed water system and are now conducting
performance tests for the automated controls, pumping station, and related components of the
system. Our system is quite unique in that our primary reclaimed water uses will be for make-up water
to UNC-Chapel Hill's cooling towers. Only a limited amount of reclaimed water will be used for irrigation
of landscaped areas and playing fields, and for toilet flushing in certain buildings on the campus.
Because of the special water quality requirements of the cooling towers, we need to operate the
reclaimed water system at a pH range of between 6.6 and 7.4 and an alkalinity range of 40 to 60. Our
reclaimed water treatment system includes a flow-paced acid feed system that gives us the ability to
trim pH and alkalinity. As part of our performance testing and related calibration of our monitoring and
control system, we need to test our system at the full range of reclaimed water flows.
Under normal conditions, when reclaimed water is actually being provided to and used in the cooling
towers, about 75 to 80% of the reclaimed water provided to UNC will be evaporated in the cooling
towers, and about 20% will be discharged to the sanitary sewer system through the cooling tower
blowdown sewer discharge points. However, in order to test the system at full demands and system
capacity, since we're not actually using the reclaimed water in the towers we must be able to
temporarily "waste" reclaimed water at much higher rates than the cooling tower sewer discharge
facilities and the gravity sewer lines on the south side of the main campus can normally handle.
Therefore, to complete the calibration and testing for the high demand condition, we need to
supplement our discharge of reclaimed water to the sanitary sewer system with a temporary reclaimed
water surface water discharge for the requested limited time period.
Quality of Reclaimed Water
Prior to discharging any reclaimed water, OWASA will de-chlorinate the water and ensure that it
otherwise meets the State's standards for reclaimed water as well as the permit limits applicable to the
Mason Farm WWTP discharge.
We believe that since the de-chlorinated reclaimed water will have undergone advanced treatment at
the Mason Farm WWTP, including multiple barrier disinfection steps, that water will be of considerably
better quality than the stormwater runoff that flows into this same box culvert.
We would immediately discontinue the temporary release in the event it appeared there could be a
problem with the reclaimed water quality.
Closing
We very much appreciate your understanding of our needs, and your consideration of this request for
approval for a temporary, limited, and controlled discharge of reclaimed water.
Our performance testing is now underway at low flows, and currently all of that water is being
discharged to the sanitary sewer system. With your near-term approval of this request, we will be able
to quickly complete the performance testing and calibration, and soon thereafter begin the beneficial
use of reclaimed water by UNC.

The facility is as described in the permit, but no wastewater has been discharged in the
last 12 months.
The following wastewater is discharged to the Mason Farms Wastewater Treatment Plant
with a maximum flow of 175,000 GPD monthly average flow:Liquid waste from the
cooling tower BD. the Cheek Clark Building and other sanitary discharge, the cooling
water from the steam quenching operation of the fly ash handling system exhausters, the
waste brine from boiler feed demineralization system, and process wastewater streams
discharged to the wastewater treatment plant (that can be pH adjusted) that include; the
discharges from the magnetic filters. No. 8 boiler building, fly ash silo washdowns,
blowoff tanks, steam traps, pump seals, and stormwater runoff from the emergency coal
pile and paved areas around the facility.
The wastewater inspection included a review of plant changes since the last inspection,
and a walk through of the plant and grounds to verify the above wastewaters discharge to
Owasa and what plans, available storage were in place should discharge need to be
retained at the UNC wastewater treatment plant on site.

The water that we are pumping off of our foundation drains has now been cleared as clean water. We can use it for
watering grass, or anything else we want. While still subject to normal NPDES permit testing, this also means we can
send it down the creek if we want to stop paying sewer charges to get rid of it.

If effluent (diffuser pipes are required) are they operating properly?
Comment During the last inspection "groundwater" was seen flowing out the outfall to
the UT to Morgan Creek. It did appear that the groundwater flow the day of this
inspection had increased significantly.
We had a recent rain event and it was explained that groundwater from the construction
of the new steam tunnel was exiting at the outfall. Since it is groundwater it was
determined that it is deemed permitted.
Comment: This facility keeps excellent records. The information was well organized
and documentation was readily available when requested for ^inspector's review.
