and in conformity with the project plan, specifications, and other supporting data subsequently filed and
approved by the Department of Environment, Health and Natural Resources and considered a part of this
permit.
This permit shall be effective from the date of issuance until April 30, 2002, shall void Permit No.
WQ0006863 issued January 27, 1993, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective actions, including those
actions that may be required by this Division, such as the construction of additional or
replacement wastewater treatment or disposal facilities.
2. This permit shall become voidable if the soils fail to adequately assimilate 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may be rescinded unless the facilities are installed, maintained, and operated in a manner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. The ponding of wastewater on the surface of the distribution field when the dosing
cycle commences shall be considered as evidence of failure of the soils to adequately
assimilate the wastewater. Additionally, such failure shall be interpreted as a violation of
this permit condition.

3 . The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Water Quality.
4. Adequate measures shall be taken to divert stormwater from the high rate infiltration area
and to prevent wastewater runoff.
Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
6. The issuance of this permit shall not relieve the Perrnittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
7. The following buffers shall be maintained:
a) 400 feet between high rate infiltration unit and any habitable residence or place of public
assembly under separate ownership or which is to be sold,
b) 200 feet between high rate infiltration unit and any private or public water supply
source and any streams classified as WS or B,
c) 200 feet from mean high water between high rate infiltration unit and any "SA" or "SB"
classified surface waters,
d) 200 feet from normal high water between high rate infiltration unit and any other
stream, canal, marsh, or coastal waters,
e) 200 feet from normal high water between high rate infiltration unit and any Class I or
Class II impounded reservoir used as a source of drinking water,
f) 200 feet between high rate infiltration unit and any other lake or impoundment,
g) 200 feet between high rate infiltration unit and any Drainage systems (ditches, drains,
surface water diversions, etc.) and from any groundwater lowering and surface
drainage ditches,
h) 100 feet between high rate infiltration unit and property lines,
i) 50 feet between treatment units and property lines, and
j) 50 feet between high rate infiltration unit and other treatment units and public right of
ways.
Some of the buffers specified above may not have been included in previous permits for
this waste treatment and disposal system. These buffers are not intended to prohibit or
prevent modifications, which are required by the Division, to improve performance of the
existing treatment facility. These buffers do, however, apply to modifications of the
treatment and disposal facilities which are for the purpose of increasing the flow that is
tributary to the facility. These buffers do apply to any expansion or modification of the
high rate infiltration areas and apply in instances in which the sale of property would cause
any of the buffers now complied with, for the treatment and disposal facilities, to be
violated. The applicant is advised that any modifications to the existing facilities will
require a permit modification.
A usable green area shall be maintained for wastewater disposal. The green area shall have
the capability of accommodating the average daily flow of the facility being served without
exceeding the loading rates of the green area. A "green area", as defined in 15A NCAC 2H
.0404 (g)(7), is an area suitable for waste disposal, either in its natural state or which has
been modified by planting a vegetative cover of grasses or low growing shrubbery.
II, OPERATION AND MAINTENANCE REQUIREMENTS
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
the wastewater treatment facilities. The operator must hold a certificate of the type and
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 11, 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 facilities shall be effectively maintained and operated as a non -discharge system to
prevent the discharge of any wastewater outside of the high rate infiltration disposal area,
which result from the operation of this facility.
4. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
5. The rotary distribution fields shall be raked twice weekly during the months April through
October and once a week during the months of November through March.
6. The screenings removed from the wastewater treatment plant shall be properly disposed in
a sanitary landfill or by other means which have been approved by this Division.
7. Vegetative growth must be kept out of the rotary distribution areas at all times. All
vegetation must be removed manually so that minimal disturbance will occur to the disposal
area.
8. The application of chemicals to the distribution field(s) is expressly prohibited.
9. An automatically activated standby power source shall be on site and operational at all
times. If a generator is employed as an alternate power supply, it shall be tested weekly by
interrupting the primary power source.
10. The flow measurement device shall be calibrated annually by a representative of a firm
which is routinely engaged in the calibration of flow measurement devices. Records of this
calibration, including all information pertinent to the calibration, shall be available during
any inspection by Division staff.
