PERMISSION IS HEREBY GRANTED TO THE
N. C. Department of Correction
Currituck County
FOR THE
continued operation of a 25,000 GPD spray irrigation treatment and disposal facility consisting of an
influent bar screen, a 45 GPM pump station with duplex pumps, high water alarms, and approximately
810 linear feet of 3 -inch force main, a 1.5 million gallon treatment and storage lagoon, hypochlorination, a
9,393 gallon chlorine contact tank with turbine pumps, a 20 HP irrigation pump, and a 7.0 acre spray
irrigation field to serve the Currituck Correction Center #4120, with no discharge of wastes to the surface
waters, pursuant to the renewal request received October 30, 1997, 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 December 31, 2002, shall void Permit
No. WQ0000550 issued June 30, 1993, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
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 co-aditions 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.
2. 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 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. Diversion or bypassing of "the untreated wastewater from the treatment facilities is
prohibited.

5 . 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 wastewdO 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 pen -nit
modification.

the top of the casing.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide the relative elevation of the measuring point for each monitoring well.
If TOC concentrations greater than 10 mg are detected in any downgradient monitoring
well, additional sampling and analysis must be conducted to identify the individual
constituents comprising this=T OC concentration. If the TOC concentration as measured in
the background monitor well exceeds 10 mg/l, this concentration will be taken to represent
the naturally occurring TOC concentration. Any exceedances of this naturally occurring
TOC concentration in the downgradient wells shall be subject to the additional sampling
and analysis as described above.
