ENVIRONMENTAL MANAGEMENT COMMISSION
DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES
RALEIGH
SPRAY IRRIGATION SYSTEM PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended,
and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
North Carolina State University
Wake County
FOR THE
continued operation of a 1000 GPD spray irrigation treatment and disposal facility consisting of a 30,000 gallon
lined anaerobic lagoon and a 29,025 sq. ft. spray irrigation field to serve North Carolina State University's
Animal Waste Management Facility, with no discharge of wastes to the surface waters, pursuant to the application
received March 9, 2005, and subsequent additional information received by the Division, and in conformity with
the project plan, specifications, and other supporting data subsequently filed and approved by the Department of
Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until August 31, 2010, shall void Permit No.
WQ0009896 issued November 1, 1999, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
The spray in-igation facilities shall be effectively maintained and operated at all times so that there is
no discharge to the surface waters, nor any contamination of ground waters which will render them
unsatisfactory for normal use. In the event that the facilities fail to perform satisfactorily, including
the creation of nuisance conditions or failure of the irrigation area to adequately assimilate the
wastewater, the Permittee shall take immediate corrective actions including those actions that may be
required by the Division of Water Quality (Division), such as the construction of additional or
replacement wastewater treatment and disposal facilities.
2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface
or groundwaters resulting from the operation of this facility.
The residuals generated from these treatment facilities must be disposed in accordance with General
Statute 143-215.1 and in a manner approved by the Division.
4. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
5. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under separate
ownership,
b) 150 feet between wetted area and property Iines,

c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between wastewater treatment units and wells, and
g) 50 feet between wastewater treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for this waste
treatment and disposal system. These buffers are not intended to prohibit or prevent modifications,
which are required by the Division, to improve performance of the existing treatment facility. These
buffers do, however, apply to modifications of the treatment and disposal facilities which are for the
purpose of increasing the flow that is tributary to the facility. These buffers do apply to any
expansion or modification of the spray irrigation areas and apply in instances in which the sale of
property would cause any of the buffers now complied with, for the treatment and disposal facilities,
to be violated. The applicant is advised that any modifications to the existing facilities will require a
permit modification.
G. Since the equipment required to be used for spray irrigation is no longer available, either an
application for Modification for this permit shall be submitted within 180 days from the date of
this permit to address the equipment needed for spray irrigation of the wastewater or an
application for Modification to an associated permit shall be submitted within 180 days from
the date of this permit to address the disposal of the wastewater from this source through
alternate means.
H. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the wastewater treatment and spray irrigation facilities by the Water Pollution
Control System Operators Certification Commission (WPCSOCC), the Permittee shall designate and
employ a certified operator to be in responsible charge (ORC) and one or more certified operator(s) to
be back-up ORC(s) of the facilities in accordance with 15A NCAC 8G .0201. The ORC shall visit
the facilities in accordance with 15A NCAC 8G .0204 or as specified in this permit and shall comply
with all other conditions specified in these rules.
I hrigation shall not be performed during inclement weather or when the ground is in a condition that
will cause runoff.
4. Adequate measures shall be taken to prevent wastewater runoff from the spray field.
The facilities shall be effectively maintained and operated as a non -discharge system to prevent the
discharge of any wastewater resulting from the operation of this facility.
6. Soil pH on all land application fields must be maintained in the optimum range for crop production.
7. A suitable year round vegetative cover shall be maintained.
8. The application rate shall not exceed a cumulative loading of 23.84 inches over any twelve (12)
month period at an instantaneous application rate not to exceed 0.25 inches per hour.
9. No type of wastewater other than that from North Carolina State University's Animal Waste
Management Facility shall be sprayed onto the irrigation area.
10. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while
normal maintenance is being performed.
11. Public access to the land application sites shall be controlled during active site use. Such controls
may include the posting of signs showing the activities being conducted at each site.

12. Freeboard in the wastewater lagoon shall not be less than two feet at any time.
13. A waste -level gauge, to monitor waste levels in the storage pond, shall be installed within 60 days of
issuance of this permit. - This gauge shall have readily visible permanent markings indicating the
maximum liquid level at the top of the temporary Iiquid storage volume, minimum liquid level at the
bottom of the temporary liquid storage volume, and top of the dam elevations. Caution must be taken
not to damage the integrity of the liner when installing the gauge.
14. A protective vegetative cover shall be established and maintained on all earthen basin embankments
(outside toe of embankment to maximum pumping elevation), berms, pipe runs, erosion control areas,
and surface water diversions. Trees, shrubs, and other woody vegetation shall not be allowed to grow
on the earthen basin dikes or embankments. Earthen basin embankment areas shall be kept mowed or
otherwise controlled and accessible.
15. Only those cleaning agents, soaps and disinfectants that are EPA approved, will not harm the cover
crop, and will not contravene the groundwater standards listed in 15A NCAC 2L may be utilized in
the subject facility. Instruction labels are to be followed when using cleaning agents, soaps and
disinfectants.
III. MONITORING AND REPORTING REQUIREMENTS
1. Any monitoring (including groundwater, surface water, soil or plant tissue analyses) deemed

contents of a sludge digester; the known passage of a slug of hazardous substance through the
facility; or any other unusual circumstances.
b. Any process unit failure, due to known or unknown reasons, that render the facility incapable of
adequate wastewater treatment such as mechanical or electrical failures of pumps, aerators,
