I. PERFORMANCE STANDARDS
Upon completion of construction and prior to operation of this permitted facility, a
certification must be received from a professional engineer certifying that the permitted
facility has been installed in accordance with this permit, the approved plans and
specifications, and other supporting materials. Mail the Certification to the Water Quality
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.

the normal office hours from 8:00 a.m, until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
3. The drip 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
Environmental Management, such as the construction of additional or replacement
wastewater treatment and disposal facilities.

4. 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.
5. 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
Environmental Management.

d) 25 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.
8. A leakage test shall be performed on the septic tank and dosing tank to insure that any
exfiltration occurs at a rate which does not exceed twenty (20) gallons per twenty-four (24)
hours per 1,000 gallons of tank capacity. The engineer's certification will serve as proof of
compliance with this condition.
9. The drip irrigation area shall be fenced with at least a two strand wire fence to help control
public access and protect the irrigation tubing. The engineer's certification will serve as
proof of compliance with this condition.
10. If excavation into bedrock is required for the installation of the septic tank or sand filter, the
pit shall be lined with a 10 mil synthetic liner.
II. OPERATION AND MAINTENANCE REQUIREMENTS
The facilities shall be properly maintained and operated at all times.
2. A suitable vegetative cover of hardwood trees shall be maintained.
3. The drip lines shall be staked to prevent mobility.
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 drip irrigation
field.
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. The application rate shall not exceed 23 inches per year at an instantaneous application rate
not to exceed 0.25 inches per hour.
No type of wastewater other than that from the Kenneth Marks Residence shall utilize the
drip irrigation area.

d. The drip irrigation system shall be inspected weekly to make certain of the emitters
proper operation, that the vegetative growth does not impede operation, that the soil is
assimilating the disposed treated wastewater with no surface runoff, and that no
objectionable odors are being generated.
III. MQNITORING AND REPORTING. REQUIREMENTS
1. Any monitoring (including groundwater, surface water, soil or plant tissue analyses)
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 IL 10 for a minimum of five years. This

hazardous substance through the facility, or any other unusual circumstances;
b. 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

directly to receiving waters without treatment of all or any portion of the influent to
such station or facility; or
d. Any time that self -monitoring information indicates that the facility has gone out of
compliance with its permit limitations.
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.

1. Any groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.

2 The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary
for the disposal system constructed after December 31, 1983, is established at either (1)
250 feet from the waste disposal area, or (2) 50 feet within the property boundary,
whichever is closest to the waste disposal area. An exceedance of Groundwater Quality
Standards at or beyond the Compliance Boundary is subject to immediate remediation
action in addition to the penalty provisions applicable under General Statute 143-
215.6A(a)(1).
3. In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the
disposal systems midway between the Compliance Boundary and the perimeter of the
waste disposal area. Any exceedance of standards at the Review Boundary shall require
remediation action on the part of the Permittee.
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

premises or place on or related to the disposal site or facility at any reasonable time for the
purpose of determining compliance with this permit, may inspect or copy any records that
must be maintained under the terms and conditions of this permit, and may obtain samples
of groundwater, surface water, or leachate.
VI. GENERAL CONDITIONS
This permit shall become voidable unless the facilities are constructed in accordance with
the conditions of this permit, the approved plans and 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

appropriate. The approval of this request will be considered on its merits and may or may
not be approved.

The following definitions shall apply ihroughoul this Subchaplor,
(1) Adivated Carbon Beds. A physical/chomical rrrlhod for reducing soluble organic material from wasiewater ellluent; The column -type beds used in this
method Kill have a flow rate varying from Iwo to eight gallons per minute per square foot and may be eaher upllow or downflow carbon beds. Carbon may
may not be reganeraled on the wastewater treatmanl plan[ site;
(2) Ae --led Lagoons, A basin in which all solids are maintained in suspension and by which biological oxidation or organic manor is reduced through ariifi&
accelerated transfer of oxygen on a flow -through basis;
(3) Aeralicn. A process of bringing about intimate contact between air or high purity oxygen in a liquid by spraying, agitation or ditfusion;(3a) Exionded
