This permit shall be effective from the date of issuance until April 30, 2005, shall void Permit No.
WQ0003271 issued July 26, 1995, 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 the Division of Water Quality (Division), such as the construction of
additional or replacement wastewater treatment or disposal facilities.
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rescinded unless the facilities are installed, maintained, and operated in a manner which will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 Division.
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 Permittee 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 CIass
11 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.
8. 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.
Ile OPERATION AND MAINTENANCE REQUIREMENTS

facility at least weekly and each Class II, III, an IV facility at least daily, excluding weekends and
holidays.
3. The application rates for the high rate infiltration system shall not exceed 10 GPD/ft2.
4. 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.
5. No traffic or equipment shall be allowed on the disposal area except while installation occurs or
while normal maintenance is being performed.
6. 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.
7. 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.
8. 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.
