continued operation of a 300 GPD spray irrigation wastewater treatment and disposal system consisting of
a 1,000 gallon baffled septic tank, a distribution box, dual 150 ft2 subsurface sand filters, a chlorine

part of this permit.
This permit shall be effective from the date of issuance until April 30, 1998, shall void Permit No.
WQ0001280 issued May 9, 1989 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 absorb the wastewater, the Permittee shall take immediate
corrective action to correct the problem, including those as may be required by the Division
of Environmental Management.
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 sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.

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,
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.
1. The facilities shall be properly maintained and operated at all times.
2. A suitable vegetative cover shall be maintained.
3. Irrigation 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.
5. The weekly application rate shall not exceed 0.2 inches/acre/week.
6. 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. No type of wastewater other than that from Blair Residence shall be sprayed onto the
irrigation area.
8. In the event that the sprinkler heads fail to achieve the design diameter 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.
9. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
10. 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 proper spray pattern, that the soil is
absorbing the disposed treated wastewater with no surface runoff, and that no
objectionable odors are being generated.
1. Any monitoring deemed necessary by the Division of Environmental Management 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 II.10 for a minimum of five years. This
information shall be provided to the Division of Environmental Management upon request.
3. Noncompliance Notification:
The Permittee shall report by telephone to the Raleigh Regional Office, telephone no. (919)
571-4700 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 render the facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, spray heads, etc.
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 15 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.
IV. INSPECTIONS
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
2. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the disposal site and facility at any reasonable time for the
purpose of determining compliance with this permit; may inspect or copy any records that
must be kept under the terms and conditions of this permit; or may obtain samples of
groundwater, surface water, or leachate.

V . GENERAL CONDITIONS
1. This permit shall become voidable unless the facilities are constructed in accordance with
the conditions of this permit, the approved plans, specifications, and other supporting data.
2. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
3. This permit is not transferable. In the event there is a desire for the facilities to change

submitted to the Division of Environmental Management accompanied by an application
fee, documentation from the parties involved, and other supporting materials as may be
appropriate. The approval of this request will be considered on its merits and may or may
not be approved.

wastewater treatment facilities shall be abandoned and all wastewater discharged into the
municipal or regional sewerage system.

7. The issuance of this permit does not preclude the Permittee from complying with any and
all statutes, rules, regulations, or ordinances which may be imposed by other government
agencies (local, state, and federal) which have jurisdiction.
8. This permit may be revoked if the Permittee fails to abide by the conditions of the operation
and maintenance agreement previously signed by the Permittee.
9. A set of approved plans and specifications for the subject project must be retained by the
Permittee for the life of the project.
10. The Permittee, at least six (6) months prior to the expiration of this permit, shall request its
extension. Upon receipt of the request, the Commission will review the adequacy of the
facilities described therein, and if warranted, will extend the Permit for such period of time
and under such conditions and limitations as it may deem appropriate.
