Dear Vice Chancellor Gray:
John E. Skvarla, !II
Secretary
Subject: Permit No. WQ0023896
UNC-CH Bingham Facility
Wastewater Irrigation System
Orange County
In accordance with your permit major modification request received August 18, 2011, and
subsequent additional information received November 14, 2011 and January 31, 2013, we are forwarding
herewith Permit No. WQ0023896 dated April 12, 2013, to The University of North Carolina at Chapel
Hill for the operation of the subject wastewater treatment and irrigation facilities.
The modifications to the subject permit are as follows:
➢ Decommissioning of the existing 8-inch gravity sewer; the ultraviolet (UV) disinfection
system; the secondary effluent storage basin pump station; the 75,843 gallon lined effluent
storage lagoon; and the 2.12 acre irrigation area composed of one field with 16 nozzles.
➢ Refurbishment of the 171,500 gallon lined effluent storage lagoon into a 125,724 gallon clay
lined secondary effluent storage basin.
➢ Reconstruction of the existing animal wastewater treatment system storage basin and
irrigation pump station.
➢ Construction and operation of an 8-inch gravity sewer system, a liquid sodium bypochlorite
disinfection system, a 525 gallon chlorine contact tank; a secondary effluent pump station and
5.72 acres of irrigation area.
Please note that on August 5, 2009, Session Law 2009-406, entitled "An Act to Extend Certain
Government Approvals Affecting the Development of Real PropertyWithin. the State," was enacted by
the General Assembly and signed into law. The Act, known as the Permit Extension Act of 2009, extends
the expiration date of certain government approvals and permits. In addition, Session Law 2010-177
extended the Act by another year. Permit No. WQ0023896 falls within the scope of this Act and is
therefore being extended until September 30, 2015. A renewal application must still be submitted six
months in advance of the extended expiration date.

lockable cap in order to reasonably ensure against unauthorized access and use. A compatible
watertight cap or seal shall be placed onto the riser pipe of the monitoring wells to prevent potential
contamination from entering the well.
6. Gauges to monitor waste levels in the wet weather storage and secondary effluent storage basins shall
be installed after their rehabilitation and prior to their operation. Caution shall be taken not to
damage the integrity of the liner when installing the gauges.
No later than six months prior to the expiration of this permit, the Permittee shall request renewal of
this permit on official Division forms. Upon receipt of the request, the Division will review the

NCAC 02T .0105(d) requires an updated site map to be submitted with the permit renewal
application.
111. PERFORMANCE STANDARDS
The subject non -discharge facilities shall be effectively maintained and operated at all times so there
is no discharge to surface waters, nor any contravention of groundwater or surface water standards.
In the event the facilities fail to perform satisfactorily, including the creation of nuisance conditions
due to improper operation and maintenance, or failure of the irrigation areas to adequately assimilate
the effluent, the Permittee shall take immediate corrective actions including Division required actions,
such as the construction of additional or replacement wastewater treatment or irrigation facilities.
2. This permit shall not relieve the Permittee of their responsibility for damages to groundwater or
surface water resulting from the operation of this facility.
All wells constructed for purposes of groundwater monitoring shall be constructed in accordance with
15A NCAC 02C .0108 (Standards of Construction for Wells Other than Water Supply), and any other
jurisdictional laws and regulations pertaining to well construction.
4. Effluent limitations shall not exceed those specified in Attachment A.
5. Application rates, whether hydraulic, nutrient or other pollutant, shall not exceed those specified in
Attachment B.
6. The irrigation system shall be connected to a rain or moisture sensor, which shall indicate when

7. The compliance boundary for the disposal system shall be specified in accordance with 15A NCAC
02L .0107(b). This disposal system was individually permitted on or after December 30, 1983;
therefore, the compliance boundary is established at either 250 feet from the effluent disposal area, or
50 feet within the property boundary, whichever is closest to the effluent disposal area. An
exceedance of groundwater standards at or beyond the compliance boundary is subject to remediation
action according to 15A NCAC 02L .0106(d)(2) as well as enforcement actions in accordance with
North Carolina General Statute 143-215.6A through 143-215.6C.
8. In accordance with 15A NCAC 02L .0108, the review boundary is established midway between the
compliance boundary and the effluent disposal area. Any exceedance of groundwater standards at the
review boundary shall require action in accordance with 15A NCAC 02L .0106.
9. The Pernnittee shall apply for a permit modification to establish anew compliance boundary prior to
any sale or transfer of property affecting a compliance boundary.

abnormal in quantity or characteristic, including the known passage of a hazardous substance.
b. Any process unit failure (e.g., mechanical, electrical, etc.), due to known or unknown reasons,
rendering the facility incapable of adequate wastewater treatment.
c. Any facility failure resulting in a by-pass directly to receiving surface waters.
d. Any time self -monitoring indicates the facility has gone out of compliance with its permit
limitations.
e. Ponding in or runoff from the irrigation sites.
Any emergency requiring immediate reporting (e.g., discharges to surface waters, imminent failure of
a storage structure, etc.) outside normal business hours shall be reported to the Division's Emergency
Response personnel at telephone number [phone], [phone], or [phone].
Persons reporting such occurrences by telephone shall also file a written report in Ietter form within
five days following first knowledge of the occurrence. This report shall outline the actions taken or
proposed to be taken to ensure the problem does not recur.

1. 4 x Year monitoring shall be conducted in March, June, September & December; Annual monitoring shall be conducted every December.
2. The measurement of water levels sball be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measurement
of pH shall be made after purging and prior to sampling for the remaining parameters.
3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top
of casing) of all monitoring wells shall be surveyed relative to a common datum.
4. Volatile Organic Compounds (VOC) - In December only, analyze by one of the following methods:
a. Standard .Method 6230D, PQL at 0.5 µg/L or less
b. Standard Method 621OD, PQL at 0.5 µg/L or less
C. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 µg/L or less
e. Another method with prior approval by the Aquifer Protection Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWQ certified to run any method used.
b. The method used must, at a minimum, include all the constituents listed in Table VM of Standard Method 6230D.
C. The method used must provide a PQL of 0.5 µg/L or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents
detected above the MDL but below the PQL of 0.5 µg/L must be qualified (estimated) and reported.
5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Raleigh Regional Office Aquifer Protection Supervisor, telephone number
[phone], must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. If TOC concentrations greater than 10 mg/L are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents
comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/L, this concentration will be taken to represent the naturally occurring
TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above.
7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure I and this attachment
