last year but did discover one unauthorized discharge that we promptly corrected.
As required by NC General Statutes Chapter 143-215.1C (a), the attached report has
also been distributed to wastewater collection system users on campus. If you have
questions regarding the report, please contact Jenny Kelvington at 919-513-7176 or

WASTEWATER COLLECTION SYSTEM
2021 PERFORMANCE REPORT
For Distribution to NC State University Wastewater Collection System Users
Annual Performance
During the calendar year 2021, NC State University operated and maintained its wastewater
collection system in accordance with Permit No. WQCS00371 and State and Federal laws with
no violations.
Sanitary Sewer Overflows
No sanitary sewer overflows (SSOs) occurred during 2021.
Unauthorized Discharge
One unauthorized discharge totaling approximately 720 gallons occurred in the spring of 2021. A
drain line from two greenhouses clogged with soil and a plug was removed to divert the watering
plants overflow from the wastewater collection system to the stormwater collection system. Most
of this overflow collected in a retention basin. Upon discovery on May 14 2021, the Utilities
Distribution Shop promptly replaced the plug and informed the greenhouse staff of why it needed
to remain in place. The N.C. Division of Water Resources Raleigh Regional Office determined
that this unauthorized discharge was not a reportable release.
Background
Wastewater collection systems are governed by North Carolina General Statute 143-215.1 C and
North Carolina Administrative Code Title 15A Chapters 2 and 8. Permit No. WQCS00371, issued
by the NC Division of Water Resources, allows NC State University to operate and maintain more
than 20 miles of sewer lines and associated piping, valves, and appurtenances required to make
a complete and operational wastewater collection system to serve the campus in an
environmentally sound manner. The sewage and wastewater collected by this system are
discharged into the City of Raleigh's wastewater collection system and treated at its Neuse River
Facility. SSOs that release more than 1,000 gallons to the ground or any amount to surface water
(including through ditches and storm drains) must be reported to the state.

A key to preventing SSOs is keeping fats, oils and grease (FOG) out of the wastewater collection
system. NC State encourages allowing FOG to cool and then be placed in a suitable container
for recycle or disposed in the trash to keep FOG out of drains. Waste Reduction and Recycling
in partnership with University Housing provides plastic "Cease the Grease" containers for FOG
collection.
NC State maintains a 24-hour Facilities Operations number [[phone]] to receive reports
of sanitary sewer overflows and dispatches emergency personnel to minimize the environmental
impact. It is likely that a SSO would be reported promptly as most sanitary sewer manholes on
campus are clearly visible to students and staff.
