be subject to the following specified conditions and limitations:
1. PERFORMANCE STANDARDS
1. Upon completion of construction and prior to operation of this permitted facility, a

damages to surface or groundwaters resulting from the operation of this facility.
5. This permit shall become voidable if the soils fail to adequately absorb the wastes
and may be rescinded unless the facilities are installed, maintained, and operated in a
manner which will protect the assigned water quality standards of the surface waters
and ground waters.
6. Adequate measures shall be taken to divert stormwater from the disposal area and
prevent wastewater runoff from the subsurface disposal field.
7. 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

required buffer requirements.
9. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
10. The following buffers shall be maintained;
a) 100 feet between disposal area and any public or private water supply including

c) 50 feet between disposal area and any stream, lake, river or natural drainageway
d) 50 feet between disposal area and property lines
e) 10 feet between disposal area and surface water interceptor drains or
diversions (upslope)
f) 25 feet between disposal area and surface water interceptor drains or diversions
(downslope) and groundwater drainage systems.
11. 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.
II. OPERATION AND MAINTENANCE REQUIREMENTS
I . The facilities shall be properly maintained and operated at all times.
2. The application rates to the disposal field shall not exceed 0.5 GPD per square foot.
3. 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.

characteristic, such as the dumping of the contents of a basin or tank; 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
