PERMISSION IS HEREBY GRANTED TO
Caroline Water Service, Inc. of NC
Currituck County
• ..
continued operation of a 4,000 GPD infiltration pond system consisting of an existing infiltration pond with a
surface area of 3,000 square feet for the disposal of backwash from greensand filters located at the Corolla Light
Water Treatment Plan, with no discharge of wastes to the surface waters, pursuant to the application received July
7, 1995 and renewal request received April 26, 2000, 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 September 30, 2005, shall void Permit No.
WQ0011284 issued December 18, 1995, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
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 this 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rescinded unless the facilities are installed, maintained, and operated in a manner which will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.
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. Adequate measures shall be taken to divert stormwater from the infiltration area and to prevent
runoff.
5. 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_

6. Diversion or bypassing of the backwash from the infiltration pond is prohibited except for the
diversion of the backwash to the existing wastewater treatment facility.
The following buffers -shall be maintained:
a) 200 feet between the infiltration pond and any private or public water supply source and any
streams classified as WS or B,
b) 200 feet from mean high water between the infiltration pond and any "SA" or "SB" classified
surface waters,
c) 200 feet from normal high water between the infiltration pond and any other stream, canal,
marsh, or coastal waters,
d) 200 feet from normal high water between the infiltration pond and any Class I or Cass II
impounded reservoir used as a source of drinking water,
e) 200 feet between the infiltration pond and any other lake or impoundment,
f) 200 feet between the infiltration pond and any Drainage systems (ditches, drains, surface
water diversions, etc.) and from any groundwater lowering and surface drainage ditches,
g) 100 feet between the infiltration pond and property lines,
h) 50 feet between the infiltration pond and other treatment units and public right of ways.
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 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 permit modification.
II. OPERATION AND MAINTENANCE RE UIREMENTS
1 _ The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Water Pollution Control Systems 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
certificate of the type and grade at least equivalent to or greater than the classification assigned to the
wastewater treatment facilities by the WPCSOCC. The Permittee must also employ a certified back-
up operator of the appropriate type and grade to comply with the conditions of 15A NCAC 8G .0202.
The ORC of the facility must visit each Class I facility at least weekly and each Class II, Ili, and IV
facility at Ieast 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.
The facilities shall be effectively maintained and operated as a non -discharge system to prevent the
discharge of any backwash outside of the infiltration disposal area which result from the operation of
this facility.
4. The application rates for the infiltration system shall not exceed 1.33 gallons per day per square foot.
No traffic or equipment shall be allowed on the disposal area except while normal maintenance is
being performed.

landfill or by other means which have been approved by the Division.

contents of a basin or tank, the known passage of a slug of hazardous substance through the
facility, or any other unusual circumstances;
b. Any process unit failure, due to known or unknown reasons, that renders the facility incapable of
adequate wastewater treatment, such as mechanical or electrical failures of pumps, aerators,
compressors, etc.;
Any failure of a pumping station, sewer Iine, or treatment facility resulting in a by-pass directly to
receiving waters without treatment of all or any portion of the influent to such station or facility;
or

or proposed to be taken to ensure that the problem does not recur.
IV. GROUNDWATER RE UIREMENTS
Existing monitor well, MW-1 and MW-2 shall be sampled every March, July, and November for
the following parameters:
Chloride Iron
TDS Water Level
pH Lead

2. The measurement of water levels must be made prior to sampling for the remaining parameters.
The depth to water in each well shall be measured from the surveyed point on the top of the

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.
5. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
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 groundwater recovery and treatment facilities to
