Permit No. WQ0023896
Dear Sir or Madam:
In accordance with the requirements of the subject permit, as specified in condition IV.14, please
find below an annual report summarizing the performance of the wastewater treatment plant
(WWTP) and drip irrigation system at The University of North Carolina at Chapel Hill's Bingham
Facility.
An electronic copy of this report has also been sent to Michael Hall of the North Carolina
Department of Environmental Quality (NC DEQ), Division of Water Resources, Raleigh Regional
Office.
Summary Description of Wastewater Treatment System
The wastewater treatment system provides secondary treatment for a permitted capacity of 3,556
gallons per day (GPD) of domestic wastewater generated from the three existing animal care
buildings at the Bingham Facility. Wastewater is conveyed to the AdvanTex secondary wastewater
treatment system via a gravity sewer collection system. The AdvanTex secondary wastewater
treatment system consists of an 8,000 gallon domestic wastewater septic tank, a 20 gallons per
minute (GPM) septic tank effluent pump station, and a 4,000 gallon AdvanTex recirculation tank
with two 55 GPM pumps to recirculate wastewater through the two AdvanTex textile media
wastewater treatment filter pods. Treated effluent from the AdvanTex system flows through a
chlorine contact tank with sodium hypochlorite injection for disinfection, an ultrasonic flow
monitoring system, and a duplex 80 GPM secondary effluent pump station to pump treated
wastewater to the 1,122,440 gallon clay -lined wet weather storage basin. A 75,843 gallon clay -
lined effluent storage basin is provided at the effluent pump station for secondary storage of
effluent. The wet weather storage basin includes a duplex 150 GPM irrigation pump station to
convey treated effluent to one of four drip irrigation zones for tertiary treatment in the soils via
uptake by the grass, trees, and shrubs in the drip irrigation fields and dispersal into the surficial
aquifer.

Beginning the week of October 10, 2022 until March 20, 2023, monitoring requirements
specified in Attachment A of the permit were not met due to a malfunction of the wastewater
system's recirculating tank. Details of the malfunction were reported to DEQ. With approval of
DEQ, pump and haul operations were initiated on October 11, 2022 and continued until March
20, 2023. Normal operations of the system restarted on March 21, 2023. There is no evidence
that partially treated wastewater reached surface waters.
Surface Water Monitoring
Analytical results of the two surface water sampling events in 2023 are included as Exhibit 1. The
NC DEQ permit for the facility does not specify limits for the parameters measured; therefore, no
exceedances were identified in 2023. Surface water quality standards are established in 15A
NCAC 2B (2B), and no exceedances of the 2B standards were identified in 2023.

Groundwater quality limits established by the NC DEQ permit for the facility, groundwater quality
standards established by 15A NCAC 2L, and exceedances identified in 2023 are shown in Tables

Groundwater at the facility has historically had low pH values. Additionally, monitoring wells
MW-3 and MW-4 have had groundwater quality exceedances for coliform since the wells were
first sampled in 2014, and it is unlikely that the exceedances are attributed to drip irrigation at the
facility. Lastly, MW-1 and MW-4 are located upgradient of the irrigation fields.
Permit Item IV.14.b. — Irrigation Meter Calibration
Irrigation meter calibration at the facility was conducted on August 7, 2023 and documentation is
included in Exhibit 3.
Permit Item IV.14.c. — Residuals
No residuals were generated in 2023.
Permit Item IV.14.d. — Soil Analysis
Attached as Exhibit 4 is a copy of the soil fertility analysis of representative soil samples taken
from the four drip irrigation fields in 2023.

Permit Item IV.14.e.- Priority Pollutant Analysis
Analytical results from a priority pollutant analysis of a sample from the wet weather storage basin,
collected on December 8, 2023, are included as Exhibit 5. The priority pollutant analyses identified
low concentrations of copper, total kjeldahl nitrogen, bromodichloromethane, chloroform,
hardness, total dissolved solids, total phosphorus, nitrite, and nitrate. These results are within
normal ranges for treated wastewater.

Sample Preservation, (Must be completed for any sample(s) incorrectly preserved or with headspace)
Sample(s) were received incorrectly preserved and were adjusted accordingly
by adding (circle one): H2504 HNO3 HCi NaOH
Time of preservation: if more than one preservative is needed, notate in comments below
Note: Notify customer service immediately for incorrectly preserved samples. Obtain a new sample or
notify the state lab if directed to analyzed by the customer. Who was notified, date and time:

Sample Preservation: (Must be completed for any sample(s) incorrectly preserved or with headspace)
j Sample(s) were received incorrectly preserved and were adjusted accordingly
by adding (circle one): H2SO4 HNO3 HCI NaOH
Time of preservation: If more than one preservative is needed, notate in comments below
Note: Notify customer service immediately for incorrectly preserved samples. Obtain a new sample or
notify the state lab if directed to analyzed by the customer. Who was notified, date and time:

Sample Preservation: (Must be completed for any sample(s) incorrectly preserved or with headspace)
Sample(s) were received incorrectly preserved and were adjusted accordingly
by adding (circle one): H2SO4 HNO3 HCI NaOH
Time of preservation: If more than one preservative is needed, notate in comments below
Note: Notify customer service Immediately for incorrectly preserved samples. Obtain a new sample or
