The facility contracts with Hepaco, Inc. for its sludge disposal services. The 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.

UNO 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. UNC may discharge once through cooling water (incoming
potable water source) from a closed loop cooling system for a short period of time, usually less
than 24 hours, if necessary during emergencies. See Process Description below.

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 closed loop cooling system is in place so that the boilers may be
operated during emergencies with once through non-contact cooling water to maintain steam to the
campus buildings, including the UNC Hospitals and to cool emergency generators. During such
emergency operation, the steam turbine generators are shut down. A process flow diagram is
attached.

Mr. Aucoin stated that there are plans to construct a new cooling tower. The new tower
will be constructed parallel to the current tower and, once in operation, the old tower will
be taken out of service. Mr. Aucoin estimated that the new cooling tower will require an
additional 35 GPM of flow that will be sent to OWASA.

The UNC Cogeneration facility produces steam and electric energy exclusively used by
the UNC Chapel Hill Campus. The facility is permitted to discharge 0.0922 MGD and
consists of: an oil/water separator, equalization basin, caustic rapid mix tank, polymer
feed system. 2 settling tanks, acid rapid mix tank. Parshall flume, and 2 stormwater
detention ponds. The permit, NC0025305. expires in July 2006 and the renewal
application has already been submitted to the State. The facility, however, has not
discharged under its permit since April 2001. as UNC has been diverting its water to
ASA. Mr. Aucoin stated that he would like to keep the permit active as a safety
precaution. The current plan has a back-up closed loop system where, in the case that
OWASA cannot accept flow, water will be discharged under NPDES mandated
guidelines. A diagram detailing the processes was included with the permit renewal.

Additionally, this letter provides notice that this office will recommend the assessment of civil penalties if
future reports are not received within the required time frame during the next twelve (12) reporting
months. The Division must take these steps because timely submittal of discharge monitoring reports is
essential to the efficient operation of our water quality programs. We appreciate your assistance in this
matter. If you have any questions about this letter or discharge monitoring reports, please contact me at
