HIGH RATE INFILTRATION SYSTEM PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended,
and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Carolina Water Service, Inc. of NC
Carteret County
continued operation of a 67,000 GPD wastewater rotary distributor facility consisting of 67,000 GPD wastewater
rotary distributor facilities consisting of an inlet bar screen and flow splitter box, a dual path treatment plant each
with a S0,000 gallon aeration basin and an 8,400 gallon clarifier, two 402 cfm blowers, a 7,500 gallon aerated
sludge holding tank, a 2,800 gallon chlorine contact tank, two tertiary filters each six feet in diameter, a 4,935
gallon mudwell, a 4,241 gallon clear well, and two rotary distributors each 100 feet in diameter, a 100 kW
automatically self -activated standby power unit, approximately 1,065 linear feet of eight inch gravity sewer,
approximately 2,300 linear feet of four -inch force main, and with all the associated piping, valves, and
appurtenances to serve Ilestron Park with no discharge of wastes to the surface waters, pursuant to the application
received November 1, 2004, 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 February 28, 2010, shall void Permit No.
WQ0003271 issued May I5, 2000, and shall be subject to the following specified conditions and limitations:
PERFORMANCE STANDARDS
1. 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.
2. 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rescinded unless the facilities are installed, maintained, and operated in a manner which will protect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.
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.
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.
The following buffers shall be maintained:
a. 10 feet between high rate infiltration unit and any on -property residential units that are to be sold
(e.g,, condominiums, subdivisions),
b. 500 feet between high rate infiltration unit and any impounded public surface water supply or
public shallow (less than 50 feet deep) ground water supply,
c. 100 feet between high rate infiltration unit and any private or public water supply source,
d. 200 feet between high rate infiltration unit and any streams classified as WS or B,
e. 200 feet from mean high water between high rate infiltration unit and any "SA" or "SB" classified
surface waters,
f. 200 feet from normal high water between high rate infiltration unit and any other stream, canal.,
marsh, or coastal waters,
g_ 200 feet from normal high water between high rate infiltration unit and any Class 1 or Class 11
impounded reservoir used as a source of drinking water,
h. 200 feet between high rate infiltration unit and any other lake or impoundment,
i. 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,
j. 50 feet between high rate infiltration unit and property lines,
k. 50 feet between treatment units and property lines, and
1. 50 feet between high rate infiltration unit and public right of ways.
Some of the buffers specified above may net 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
pen -nit modification.
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.
11. OPERATION AND MAINTENANCE REQUIREMENTS
The facilities shall be properly maintained and operated at all times.
2. Upon classification of the wastewater treatment and spray irrigation facilities by the Water Pollution
Control System Operators Certification Commission (WPCSOCC), the Permittee shall designate and
employ a certified operator to be in responsible charge (ORC) and one or more certified operator(s)
to be back-up ORC(s) of the facilities in accordance with 15A NCAC 8G .0201. The ORC shall visit
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.

3. The application rates for the high rate infiltration system shall not exceed 10 GPDIft'.
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 that 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.
9. The application of chemicals to the distribution field(s) is expressly prohibited.
10. An automatically activated standby power source shall be on site and operational at all times. If a
generator is employed as an alternate power supply, it shall be tested weekly by interrupting the
primary power source.
11. Diffusers shall be cleaned as needed to ensure that adequate aeration is provided. Records of this
maintenance shall be maintained by the Permittee.
12. The chlorine tablets used in the disinfection facility shall be of the kind and type specified in the
plans and specifications approved by the Division.
I11. MONITORING AND REPORTING REQUIREMENTS
