SINGLE FAMILY SPRAY IRRIGATION 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
William L. Robinson
Craven County
FOR THE
continued operation of a 360 GPD spray irrigation wastewater treatment and disposal system consisting of
a 1,000 gallon baffled septic tank, a 77 ft2 recirculating sand filter, a tablet chlorinator, dosing tank, and a
9,474 ft2 spray irrigation area to serve the Robinson Residence, with no discharge of wastes to the surface
waters, pursuant to the application received August 26, 1997, and in conformity with the project plan,
specifications, and other supporting data subsequently filed and approved by the Department of
Environment, Health and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until August 31, 2002, shall void Permit
No. WQ0007288, issued March 24, 1993, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
The spray 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 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, 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 North Carolina Division of
Water Quality.
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 drainageways 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.
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.
H. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of
the wastewater treatment facilities. The operator must hold a certificate of the type and
grade at least equivalent to or greater than the classification assigned to the wastewater
treatment facilities by the Certification Commission. The Permittee must also employ a
certified back-up operator of the appropriate type and grade to comply with the conditions
of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter 8A, .0202.
3. A suitable 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.
5. Adequate measures shall be taken to prevent wastewater runoff from the spray field.
6. The application rate shall not exceed 0.038 GPD per square foot.
7. 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.
8. No type of wastewater other than that from the Robinson Residence shall be sprayed onto.
the irrigation area.
9. In the event that the sprinkler heads fail to achieve the design diameter feet due to
obstructions, the obstructions shall be removed or the sprinkler heads shall be raised and
supported to such height that the design diameter is achieved.

1 D. No traffic or equipment shall be allowed on the disposal area except while installatiork
occurs or while normal maintenance is being performed.
11. The spray irrigation field shall be fenced with at least a two strand wire fence.
12. The Permittee is responsible for the operation and maintenance of the entire treatment and
disposal system including, but not limited to, the following items:
a. The septic tank shall be checked annually and pumped out as needed.
b. The tablet chlorinator shall be checked every week. Tablets shall be added so as to
provide proper chlorination.
c_ The storage, pump, and alarm systems shall be inspected weekly. The scum layer shall
be removed at the same interval as the septic tank is cleaned out.
d . The spray system shall be inspected weekly to make certain of the sprayers proper
operation, that the vegetative growth allows a proper spray pattern, that the soil is
assimilating the disposed treated wastewater with no surface runoff, and that no
objectionable odors are being generated.
III. MONITORING AND REPORTING REQUIREMENTS
Any monitoring deemed necessary by the Division of Water Quality to insure surface and
ground water protection will be established and an acceptable sampling reporting schedule
shall be followed.
2. The Permittee shall maintain records of all maintenance performed on the system and
irrigation area, as required in Condition 11 12 for a minimum of five years. This
information shall be provided to the Division of Water Quality upon request.
3. Noncompliance Notification:

number [phone], as soon as possible, but in no case more than 24 hours or on the
next working day following the occurrence or first knowledge of the occurrence of any of
the following:
a. Any process unit failure, due to known or unknown reasons, that renders the facility
incapable of adequate wastewater treatment, such as mechanical or electrical failures of
pumps, spray heads, etc.; or
b. Any failure of a pumping station or treatment facility resulting in a by-pass directly to
receiving waters without treatment of all or any portion of the influent to such station or
facility.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within five (5) days following first knowledge of the occurrence. This report must
outline the actions taken or proposed to be taken to ensure that the problem does not recur.

disposal system including, but not limited to, the following items:
a. The septic tank shall be checked every six (6) months and pumped out as required.
b. The tablet chlorinator shall be checked every week until the actual usage rate is established
and thence on a monthly basis. Tablets shall be added so as to provide proper chlorination_
c. The storage system, pump system, and alarm system shall be inspected monthly. The
scum layer shall be removed at the same interval as the septic tank is cleaned out.
d. The spray system shall be inspected monthly to make certain of the sprayers proper
operation, that the vegetative growth allows proper spray patterns, that the soil is absorbing
the disposed treated wastewater with no surface runoff, and that no objectionable odors are
being generated_
2. Failure of the Permittee to properly operate this system is subject to a penalty up to $10,000 per
day.
3. Failure to meet permit conditions or violation of the State's surface or groundwater regulations
will require cessation of occupancy of the residence.
