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be rescinded unless the facilities are installed, maintained, and operated in a manner which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.

6. Adequate measures shall be taken to divert storrnwater 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.
IL DPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
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

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 holidays,
and must properly manage and document daily operation and maintenance of the facility
and must comply with all other conditions of Title 15A, Chapter 8A, .0202.
3. The application rates to the disposal fields shall not exceed:

0.3 gallons per day per square foot on Field B
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.

reporting schedule shall be followed.
2. The low pressure lines shall be maintained as necessary (including purging of the lines and
pressure testing) in order to ensure that they remain free of obstructing materials and that
the pressure head on the laterals remains within the design specifications. The highest and
lowest laterals on each subfield shall be checked (and adjusted as necessary) annually to

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
maintenance shall be maintained by the Permittee.
These records should include but are not limited to the following:
