excluding State Holidays.

4. 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.
5. 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.
6. This permit shall become voidable if the soils fail to adequately absorb the wastes and may
he. reccinded 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.

wastewater runoff from the subsurface disposal field.
8. 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.
9. A usable reserve area shall be maintained for wastewater disposal. The reserve area shall
ilavt the capability of accommodating the average daily flow of the facility being served
V iawat exceeding the loading rates of the reserve area while meeting all required buffer
requirements.
10. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
11. 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.
12. 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.
2

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 (ORC) of

grade at least equivalent to or greater than the classification assigned to the wastewater
treatment facilities by the Certification Commission. The Permittee must also employ a
certified back-up operator of the appropriate type and grade to comply with the conditions
of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and

treatment facilities are 50% complete.
3. The application rates to the disposal field shall not exceed 0.40 GPD/ft2.
4. 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.
5. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
6. A suitable cover shall be maintained on the disposal area and the disposal area shall be
routinely mowed. The clippings shall be periodically removed to prevent the build-up of
thatch.
7. The pressure heads on the two (2) manifolds shall be inspected periodically to ensure even
distribution to all of the force main lines.
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 nitrification lines shall be maintained as necessary (including purging of the lines) in
order to ensure that they remain free of obstructing materials. Adequate records showing
all maintenance shall be maintained by the Permittee.
3. A record shall be maintained of all residuals removed from this facility. This record shall

municipality agreeing to accept the residuals, date the residuals were hauled, and volume of
residuals removed.

applicant for the life of the project.
5. The annual administering and compliance fee must be paid by the Permittee within thirty
