excluding State Holidays.
3. In the event that the facilities fail to perform satisfactorily, including the creation of

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. 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be rescinded unless the facilities are installed, maintained, and operated in a manner which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 Carolina Division of
Environmental Management.
8. A usable reserve area shall be maintained for wastewater disposal. The reserve area shall
have the capability of accommodating the average daily flow of the facility being served
without exceeding the loading rates of the reserve area while meeting all 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 existing public or private water supply
including wells as of this date excluding any potable wells constructed by the Wake
County Public School System,
b) 100 feet between disposal area and "SA and SB" classified surface waters,
C) 50 feet between disposal area and any stream, lake, river or natural drainageway,
d) 50 feet between disposal area and property lines,
C) 10 feet between disposal area and surface water interceptor drains or diversions
(upslope), and
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)
hour per 1,000 gallons of tank capacity. The engineer's certification will serve as proof of
compliance with this condition.
1. The facilities shall be properly maintained and operated at all times.

Certification Commission. Once the facility is classed, the Permittee must submit a letter
to the Certification Commission which designates the operator in responsible charge within
thirty days after the wastewater treatment facilities are 50% complete.

allowed with concurrence from the Raleigh Regional Waster Quality Supervisor at (919)
733-2314.

necessary to the highest and lowest laterals, the remaining laterals in that subfield shall also
be checked and adjusted to the approved specifications. Adequate records showing all
