RALEIGH
SURFACE 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
Caswell County Schools
Caswell County
FOR THE
continued operation of a 3,500 GPD surface irrigation treatment and disposal facility consisting of a 11,000 gallon
septic tank, a 413,610 gallon two compartment lagoon (30 days treatment in one, storage in other), a chlorinator
and all pumps, valves and appurtenances necessary for surface irrigation to approximately 3.12 acres to serve
Stoney Creek Elementary School, with no discharge of wastes to the surface waters, pursuant to the application
received October 22, 2002, 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 December 31, 2007, shall void Permit No.
WQ0006941 issued July 31, 1997, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1_ The surface irrigation 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 there
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.
3. 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 lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainage ways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between treatment/storage units and any wells, and
g) 50 feet between treatment units and property lines.
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 that 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
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.
6. The disposal system shall be connected to a rain or moisture sensor, if a certified operator is NOT
designated, that shall indicate when wastewater application is not appropriate in accordance with
Condition 11(4) of this permit.
II. OPERATION AND MAINTENANCE REQUIREMENTS
The facilities shall be properly maintained and operated at all times.
2. Upon classification of the wastewater treatment and irrigation facilities by the Water Pollution
Control System Operators Certification Cornmission (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 SG .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.
3. A suitable year round vegetative cover shall be maintained.
4. Irrigation shall not be performed during inclement weather or when the ground is in a condition that
will cause runoff.
Adequate measures shall be taken to prevent wastewater runoff from the irrigation 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.
7. The application rate shall not exceed a cumulative loading of 18.72 inches over any twelve (12)
month period at an instantaneous application rate not to exceed 0.3 inches per hour.
No type of wastewater other than that from Stoney Creek Elementary School shall be irrigated onto
the irrigation area.
9. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while
normal maintenance is being performed.
10. 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.
11. Freeboard in the lagoon shall not be less than two feet at any time.

12. 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 liquid 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.
13. 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,

otherwise controlled and accessible.

necessary by the Division to insure surface and ground water protection will be established and an
acceptable sampling reporting schedule shall be followed.
2. Influent flow shall be continuously monitored and daily average flow values shall be reported on
Form NDMR. Flow may be estimated from water use records provided water use is metered. Daily
average values shall be calculated by dividing monthly flow volume by the number of days in the
month.
3. The effluent from the subject facilities shall be monitored by the Permrttee at the point prior to
irrigation every May, September and January for the following parameters:
BOD5 TSS
Fecal Coliform pH
