amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Holiday Island Property Owners Association
Perquimans County
FOR THE
continued operation of a 10,000 GPD constructed wetlands wastewater treatment facility which consists
of the following facilities: a collection system, an influent pump station, a 10,000 GPD extended
aeration package wastewater treatment plant with residuals holding, a 10,000 gallon aerated holding
tank, dual tertiary filters, dual effluent pumps with high water alarm, and approximately 2,700 linear feet
of four inch force main; and the construction and operation of a constructed wetlands system which
consists of a flow splitter box, three identical parallel constructed wetland cells consisting of
approximately 8,500 square feet each with a total of three cells (each cell is 80 feet by 106 feet) with cell
walls having a permeability of 10-6 cm/sec. and a clay liner on the bottom, with effluent collection and
distribution lines and all other piping, valves and appurtenances to serve the Holiday Island Property
Owners Association facilities with no discharge of wastes to the surface waters, pursuant to the
application received March 17, 1998, 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 August 31, 2003, shall void Permit
No. WQ0002519, which was issued October 11, 1994, and shall be subject to the following specified
conditions and limitations:
I. PERFORMANCE STANDARDS
1. The Washington Regional Office, telephone number 919-946-6481, 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.
2. 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 and disposal facilities.
3. 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.
4. 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.
5. Adequate measures shall be taken to divert stormwater from the disposal area and prevent
wastewater runoff from the disposal area.
6. 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.
7. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
8. The following buffers shall be maintained:
a) 100 feet between disposal area and any public or private water supply including wells
b) 100 feet between disposal area and "SA and SB" classified surface waters
c) 50 feet between disposal area and any stream, lake, river or natural drainageway
d) 50 feet between disposal area and property lines
e) 10 feet between disposal area and surface water interceptor drains or diversions
(upslope)
f) 25 feet between disposal area and surface water interceptor drains or diversions
(downslope) and groundwater drainage systems..
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
facilities 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.
II. OPERATION AND MAINTENANCE REQUIREMENTS
1. 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 Permittec 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
letter to the Certification Commission which designates the operator in responsible
charge within thirty days after the wastewater treatment facilities are 50% complete.
3. The application rates to the wetland cells shall not exceed 0.93 GPD per square foot, or
an application rate which will not result in a discharge to surface waters, whichever is
less.
2
4. 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.
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 screenings removed from the wastewater treatment plant shall be properly disposed
in a sanitary landfill.
7. The Division maintains the right to require that appropriate dual source, dual feed, or
standby power provisions be included for these facilities, should one of these options
become necessary for the protection of the health of the citizens of North Carolina or its
natural resources.
8. 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
the calibration, including all information pertinent to the calibration, shall be available
during any inspection by Division staff.
9. Diffusers shall be cleaned as needed to assure adequate aeration. Records of maintenance
shall be maintained by the permittee.

protection will be established and an acceptable sampling reporting schedule shall be
followed.
2. Adequate records shall be maintained by the Permittee, which shows all maintenance
performed at the wastewater treatment and disposal facilities.
3. As an indicator of proper operation and maintenance, the facility shall produce and

15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary
is for the disposal system constructed after December 31, 1983 is established at either (1)
250 feet from the waste disposal area, or (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.
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.
V. INSPECTIONS
Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.

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
