The University of North Carolina at Chapel Hill contracts with Hepaco, Inc. and EPS of Vermont,
Inc. for its sludge disposal services. The Cogeneration facility’s basins are monitored regularly
for sludge accumulation and are generally cleaned on a semi-annual basis. The non-hazardous
sludge is removed and transported to Hoh Corporation, 1701 Vargrave St., Winston Salem, North
Carolina for disposal by entering it into their bulk solidification program. If you have any
questions regarding our sludge management practices, please contact Timothy Aucoin at
919.962.1309.

THE UNIVERSITY
of NORTH CAROLINA
at CHAPEL HILL
The University the North Carolina at Chapel Hill (UNC-Chapel Hill) is hereby requesting renewal
of NPDES Permit No. NC0025305, issued for the treatment and discharge of wastewater from the
UNC-Chapel Hill Cogeneration Facility. Please note that UNC-Chapel Hill operates the process
wastewater treatment facility at Cogen in a non-discharge mode (i.e., no treated process
wastewater is discharged to the receiving stream). Instead, all treated process wastewater is
discharged to the Orange Water and Sewer Authority (OWASA). However, UNC-Chapel Hill is
seeking to renew its NPDES permit so that, in the event of an emergency, or if OWASA does not
have the capacity to accept the treated process wasterwater, UNC-Chapel Hill continues to have
the option to discharge treated process wastewater to the stream. There have been no
occasions in the last five years when there was a discharge from the facility to the receiving
stream. The original and two copies of the application for renewal are enclosed.

separate sheet of paper with the system description.
Attached Figure F-l provides a water balance schematic for the UNC Cogeneration facility. The
principal wastewater generating processes are threefold: (1) an estimated 15,000 gallons per
day (gpd) of water from miscellaneous facility uses, (2) an estimated 12,000 gpd of stormwater
run-off from the coal pile, and (3) and estimated 28,600 gpd of stormwater run-off from the fuel
oil containment area and general process area. Collectively, these flows represent
approximately 55,600 gpd of low strength wastewater treated by the on-site system. All
sanitary wastewater is discharged directly to the local publically-owned treatment works, the
Orange Water and Sewer Authority (OWASA).

UNC operates the process wastewater treatment facility as a non-dischage facility with the
option to discharge to the stream in an emergency situation if OWASA (local POTW) is unable
to accept the wastewater flow. The emergency once-through cooling water loop shown in the
previous permit application has been removed and is no longer available for use. Sludge
disposal is described in the sludge management letter included with this application.

In normal operation, the Cogeneration Facility produces steam and electric energy that is 100% used
on the UNC campus. The facility is not covered in the Steam and Electric Power category' under 40
CFR Part 423. Coal and natural gas are used as the energy' source for combustion with No. 2 Fuel Oil
used as a back-up energy source. A process flow diagram is attached. Permit applications have been
filed to allow' the combustion of torrified wood, wood chips, or pelletized woody biomass if these
materials become available as alternative fuels. Use of these fuels, if it occurs, will be to reduce
greenhouse gas emissions.
