This permit shall be effective from the date of issuance until July 31, 2003, shall void Permit No.
WQ0015052 issued August 24, 1998, and shall be subject to the following specified conditions and limitations:
T. PERFORMANCE STANDARDS
1. The reclaimed water utilization facilities shall be effectively maintained and operated at all times so
that there is no discharge to the surface waters, nor any contamination of ground waters which will
render them unsatisfactory for normal use. In the event that the facilities fail to perform
satisfactorily, including the creation of nuisance conditions or failure of the irrigation area to
adequately assimilate the wastewater, 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 and disposal facilities.
2. 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.

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. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
The following buffers shall be maintained:
a. 100 feet between wetted areas and water supply wells,
b. 100 feet between wetted areas and waters classified as SA,
c. 25 feet between wetted areas and surface waters not classified as SA,
d. 100 feet between wastewater treatment units and wells,
e. 50 feet between reclaimed water storage/irrigation ponds and property lines, and
f. 50 feet between wastewater treatment units and property lines.
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 that 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 irrigation 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.
6. Public access to the irrigation sites shall be controlled during active site use. Such controls may
include the posting of signs showing the activities being conducted at each site. A sign shall be
posted in plain sight in the club house showing these activities.
H. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the wastewater treatment and irrigation facilities by the Water Pollution
Control System Operators -Certification Commission (WPCSOCC), the Permittee shall designate and

the facilities in accordance with 15A NCAC 8G .0204 or as specified in this permit and shall comply
with all other conditions specified in these rules.
A suitable, year-round vegetative cover shall be maintained on the irrigation areas.
4. Irrigation shall not be performed during inclement weather or when the ground is in a condition that
will cause runoff.
5. Adequate measures shall be taken to prevent wastewater runoff from the irrigation field.
6. 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.
7. The application rate shall not exceed a cumulative loading of three inches per week.
8. No type of wastewater other than that from the residential subdivision shall be irrigated onto the
irrigation area.

9. All wastewater shall be routed to the rapid infiltration spray bed should the limit for fecal colifoTm
(daily maximum concentration of 25 per 100 mI) or turbidity (instantaneous maximum of 10 NTU)
