considered a part of this permit.
This permit shall be effective from the date of issuance until September 30, 2001, and shall be
subject to the following specified conditions and limitations:

1. PERFORMANCE STANDARDS
1. Upon completion of construction and prior to operation of this permitted facility, a
certification must be received from a professional engineer certifying that the permitted
facility has been installed in accordance with this permit, the approved plans and
specifications, and other supporting materials. Mail the Certification to the Water Quality
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
2. The Wilmington Regional Office, telephone number [phone], shall be notified at
least forty-eight (48) hours in advance of operation of the installed facilities so that an in -
place inspection can be made. Such notification to the regional supervisor shall be made
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, 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 groundwaters resulting from the operation of this facility.
5. 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.
6. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
7. The following buffers shall be maintained:
a) 100 feet between wetted area and water supply wells,
b) 100 feet between wetted area and waters classified as SA,
c) 100 feet between wastewater treatment units and wells,
d) 50 feet between wastewater treatment units and property lines, and
e) 25 feet between wetted area and surface waters not classified as SA.
8. 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. A sign shall be posted in plain sight in the club house showing these activities.
11. OPERATION AND MAINTENANCE REQUIREMENTS
The facilities shall be properly maintained and operated at all times.
2. A suitable vegetative cover shall be maintained on the spray irrigation areas.
3. Irrigation shall not be performed during inclement weather or- when the ground is in a
condition that will cause runoff.
4. Adequate measures shall be taken to prevent wastewater runoff from the spray field.
5. 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.

6. 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 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. Once
the facility is classified, the Permittee must submit a Ietter to the Certification Commission
which designates the operator in responsible charge within thirty days after the wastewater
treatment facilities are 50% complete.

an instantaneous application rate not to exceed 0.15 inches per dose
8. No type of wastewater other than that from the Sea Trail Corporation shall be sprayed onto
the irrigation area.
9. All wastewater shall be routed to the five-day holding pond should the limit for fecal
coliform (daily maximum concentration of 25 per 100 ml) or turbidity (instantaneous
maximum of 10 NTU) be exceeded, until such time that the problems associated with the
treatment capability of the wastewater treatment plant have been corrected. The wastewater
in the five-day holding pond shall be pumped back to the treatment plant for retreatment or
treated in the five-day pond prior to discharge to the storage pond.

inspection of the lagoon liner, and prior to waste disposal operations, verification of the
liner's compliance with hydraulic conductivity and thickness specifications must be
provided to the Division of Water Quality, Groundwater Section, by the project engineer.
V . INSPECTIONS
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal facilities
to prevent malfunctions and deterioration, operator errors and discharges which may cause
or lead to the release of wastes to the environment, a threat to human health, or a nuisance.
The Permittee shall keep an inspection log or summary including at least the date and time
of inspection, observations made, and any maintenance, repairs, or corrective actions taken
by the Permittee. This log of inspections shall be maintained by the Permittee for a period
of three years from the date of the inspection and shall be made available upon request to
the Division of Water Quality or other permitting authority.

submitted to the Division of Water Quality accompanied by an application fee,
documentation from the parties involved, and other supporting materials as may be
appropriate. The approval of this request will be considered on its merits and may or may
not be approved.
4. Failure to abide by the conditions and limitations contained in this permit may subject the
Permittee to an enforcement action by the Division of Water Quality in accordance with
North Carolina General Statute 143-215.6(a) to 143-215.6(c).
