surface waters, pursuant to the application received April 8, 1999 and in conformity with the project plan,
specifications, and other supporting data subsequently filed and approved by the Department of Environment and
Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until January 31, 2002, shall void Permit No.
WQ00021.61 issued February 13, 1997, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. Upon completion of construction and prior to operation of the new facilities for the multipurpose center, a
certification must be received from a professional engineer certifying that the permitted units have been
installed in accordance with this permit, the approved plans and specifications, and other supporting
materials. Mail the Certification to the Non -Discharge Permitting Unit, Division of Water Quality, 1617
Mail Service Center, Raleigh, NC 27699-1617.

2. The Raleigh Regional Office, telephone number 919-571-4700 shall be notified at least forty-eight (48)
hours in advance of operation of the newly installed facilities so that an in -place inspection can be made.
Such notification to the regional supervisor shall be inade during the normal office hours from 8.00 a.m.
until 5:00 p.m. on Monday through Friday, excluding State Holidays.
3. The spray irrigation 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.
4. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or
graundwaters resulting from the operation of this facility.
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.
Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
7. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under separate
ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between wastewater treatment units and wells, and
g) 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 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 spray 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.
8. A leakage test shall be performed on the new septic tank and new pump station to insure that any
exfiltration occurs at a rate which does not exceed twenty (20) gallons per twenty-four (24) hours per
1,000 gallons of tank capacity. The engineer's certification will serve as proof of compliance with this
condition.
H. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.

2. Upon classification of the facility by the Water Pollution Control System Operators Certification
Commission (WPCSOCC), 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 certifica
of the type and grade at least equivalent to or greater than the classification assigned to the wastewater
treatment facilities by the WPCSOCC. The Perrnittee must also employ a certified back-up operator of the
appropriate type and grade to comply with the conditions of 15A NCAC 80 .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 15A NCAC 8G .0202.
3. A suitable year round vegetative cover shall be maintained.
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 spray 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 52 inches over any twelve (12) month period
at an instantaneous application rate not to exceed 0.25 'inches per hour.
8. No type of wastewater other than that from Carolina Friends School shall be sprayed onto the irrigation
area.
9. No traffic or equipment shall be allowed on the disposal area except while installation occurs or whi'
normal maintenance is being performed.
10. Public access to the land application sites shall be controlled during active site use. Such controls may
include the posting of signs showing the activities being conducted at each site.
III. MONITORING AND REPORTING RE UIREMENTS
Any monitoring (including groundwater, surface water, soil or plant tissue analyses) deemed necessary by
the Division to insure surface and ground water protection will be established and an acceptable sampling
reporting schedule shall be followed.

(2) 50 feet within the property boundary, whichever is closest to the waste disposal area. An exceedance
of Groundwater Quality Standards at or beyond the Compliance Boundary is subject to immediate
remediation action in addition to the penalty provisions applicable under General Statute 143-
215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal systems
midway between the Compliance Boundary and the perimeter of the waste disposal area. Any exceedance
of standards at the Review Boundary shall require remediation action on the part of the permittee.
