surface waters, pursuant to the renewal request received March 16, 1993, 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 April 30, 1998, shall void Permit No.
WQ0000267 issued December 5, 1988 and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. 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 absorb the wastewater, the Pernuttee shall take such immediate
corrective action to correct the problem, including actions as may be required by the
Division of Environmental Management.
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.
3. The sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.

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,

f) 100 feet between wastewater treatment units and wells,
g) 50 feet between wastewater 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 permit
modification.
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 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 11, 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.
3. A suitable vegetative cover shall be maintained.
4. Irrigation shall not be performed during inclement weather or when the ground is in a
condition that will cause runoff.
5. Adequate measures shall be taken to prevent wastewater runoff from the spray field
6. 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.
7. The average annual weekly application rate shall not exceed 1.0 inches at an instantaneous
application rate not to exceed 0.3 inches per hour.
S. No type of wastewater other than that from NCDOC`s Gates Correctional Center shall be
sprayed onto the irrigation area.
2

9. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
10. 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.
11. Freeboard in the treatment/storage lagoon shall not be less than two (2) feet at any time.
12. The facility shall expand the subject spray irrigation area to utilize the entire 7.0 acres that
was originally permitted in Permit No. WQ0000267 before November 21, 1993. In
addition, stormdrains within the prison complex which drain into the wastewater treatment
and disposal system shall be rerouted by November 21, 1993,

5. Noncompliance Notification:
The Permittee shall report by telephone to the Washington Regional Office, telephone no.
[phone] as soon as possible, but in no case more than 24 hours or on the next
working day following the occurrence or first knowledge of the occurrence of any of the
following:
a. Any occurrence at the wastewater treatment facility which results in the treatment of
significant amounts of wastes which are abnormal in quantity or characteristic, such
as the dumping of the contents of a sludge digester, 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 render the facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, aerators, compressors, etc.
C. Any failure of a pumping station, sewer line, 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.
d. Any time that self-monitoring information indicates that the facility has gone out of
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 days following first knowledge of the occurrence. This report must outline
the actions taken or proposed to be taken to ensure that the problem does not recur.
IV. CzROUNDWATER ,REQUIREMENTS
The four (4) existing monitor wells shall be sampled every March, July and November for
the following parameters:
NO3 Total Dissolved Solids
TOC pH
Ammonia Nitrogen Chloride
Water Level Fecal Coliforms
Volatile Organic Compounds - In November only (by Method 1 or Method 2 below)
Method 1: Method 6230D (Capillary - Column), "Standard Methods for the
Examination of Water and Wastewater", 17th edition, 1989
Method 2: Method 502.2 "Methods for the Determination of Organic Compounds in
Drinking Water", United States Environmental Protection Agency - 600/4-
88/039
The measurement of water level must be made prior to sampling for the remaining
parameters. The depth of water in each well shall be measured from the surveyed point on
the top of the casing.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide relative elevations of the measuring point for each of the monitoring wells.
4

If TOC concentrations greater than 10 mg/l are detected in any downgradient monitoring
well, additional sampling and analysis must be conducted to identify the individual
constituents comprising this TOC 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.
If any volatile organic compounds are detected by method 6230D, or the equivalent method
502.2, then EPA methods 604 and 611 must also be run to detect other organic compounds
which may be present. The results of all analysis specified in the monitoring requirements,
including 604 and 611 if required, must be submitted simultaneously.
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management, Post Office Box 29535, Raleigh, N.C. 27626-0535 on Form
GW -59 (Compliance Monitoring Report Form) every April, August and December.
2. The -Compliance „BQundarX for the disposal system is specified by regulations in 15 NCAC
2L, Groundwater Classifications and Standards. An exceedance of Groundwater Quality
Standards beyond the Compliance Boundary is subject to penalty provisions applicable
under General Statute 143-215.6(1)a.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the lagoon and sprayfield, or 50 feet within the
property boundary.
Any sale or transfer property which affects the location of the compliance boundary shall be
reported immediately to the Director. The permittee shall not transfer land within an
established compliance boundary unless the permittee has satisfied all the requirements of
15A NCAC 2L .107 (e and f).
The REVIEW BOUNDARY for the disposal system is specified by regulations in 15
NCAC 2L, Groundwater Classifications and Standards. A REVIEW BOUNDARY is
established around disposal systems midway between the Compliance Boundary and the
perimeter of the waste disposal area. When the concentration of any substance equals or
exceeds the maximum allowable concentration of that substance at the REVIEW
BOUNDARY, as determined by monitoring, the permittee shall giLher (i) demonstrate,
through predictive calculations or modeling, that natural site conditions, facility design and
operational controls will prevent a violation of standards at the Compliance Boundary; or,
(ii) submit a plan for the alteration of existing site conditions, facility design or operational
controls that will prevent a violation of standards at the Compliance Boundary, and
implement that plan upon its approval by the Director.
3- 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.
5

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

request to the Division of Environmental Management or other permitting authority.
3. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the disposal site and facility at any reasonable time for the
purpose of determining compliance with this permit; may inspect or copy any records that
must be kept under the terms and conditions of this permit; or may obtain samples of
groundwater, surface water, or leachate.
This permit shall become voidable unless the facilities are constructed in accordance with
the conditions of this permit, the approved plans, specifications, and other supporting data.
2. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
3. This permit is not transferable. In the event there is a desire for the facilities to change
ownership, or there is a name change of the Permittee, a formal pennit request must be
submitted to the Division of Environmental Management 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 Environmental Management in
accordance with North Carolina General Statute 143-215.6A to 143-215.6C.
5. The issuance of this permit does not preclude the Permittee from complying with any and
all statutes, rules, regulations, or ordinances which may be imposed by other government
