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. Mail the Certification to the Permits and Engineering Unit, P.O. Box
29535, Raleigh, NC 27626-0535.
2. The Winston-Salem Regional Office, phone no. 919/896-7007, shall be notified at least
forty-eight (48) hours in advance of backfilling of the installed facilities so that an in-place
inspection can be made. Such notification to the regional supervisor shall be made during
the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
3. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those
as may be required by this Division, such as construction of additional or replacement
wastewater treatment or 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. 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be rescinded unless the facilities are installed, maintained, and operated in a manner which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.
b. 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 public or private water supply including
wells
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
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 Ieakage test shall be performed on the septic tank and oil/water separator 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.
II. OPERATION AND MAINTENANCE REQUIREMENTS

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 of the
wastewater treatment facilities. The operator must hold a certificate of the type and grade at
least equivalent to the classification assigned to the wastewater treatment facilities by the
Certification Commission. Once the facility is classified, 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.
