November 4, 1992, 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 January 31, 1998, shall void Permit
No. 16206 issued May 16, 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 there 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 Permittee 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 Perrnittee 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,
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,
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.
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 Pemuttee 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 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.
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 daily application rate shall not exceed 0.125 inches not to exceed thirty-
five (35) minutes per day.
2

8. No type of wastewater other than that from U.S. Naval Aerial Target Facilities at Piney
Island (BT-11) shall be sprayed onto the irrigation area.
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. Routine maintenance on at least a weekly basis must be performed on the sand filter units to
keep the surface free of vegetation and organic material. If clogging results in exessive
ponding of wastewater, the filter sand must be removed and replaced as necessary. The
sand must be maintained at a depth of at least 24 inches.
III. MQNITORING AND REPORTINCzREQUIREMENTS
1. Any monitoring (including groundwater, surface water, soil or plant tissue analyses)
deemed necessary by the Division of Environmental Management to insure surface and
ground water protection will be established and an acceptable sampling reporting schedule
shall be followed.
2. Adequate records shall be maintained by the Permittee tracking the amount of wastewater
disposed. These records shall include, but are not necessarily limited to the following
information:
a) date of irrigation,
b) volume of wastewater irrigated,
c) field irrigated,
d) length of time field is irrigated,
e) continuous weekly, monthly, and year-to-date hydraulic (inches/acre) loadings for
each field,
f) weather conditions, and
g) maintenance of cover crops.
3. The effluent from the subject facilities shall be monitored by the Permittee at the point prior
to irrigation every March, July and November for the following parameters:
BOD5 TSS
Fecal Coliform pH
NH3 as N
4. Three copies of all operation and disposal records (as specified in condition III 2) and all
effluent monitoring data (as specified in condition I11 3) and any other data as may be
required shall be submitted on or before the last day of the following month to the

Boundary is subject to penalty provisions applicable under General Statute 143-215.6A.
The sale of property, by the Permittee, which is within or contiguous to the disposal
system site may alter location of the Compliance Boundary.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the disposal system, or 50 feet within the property
boundary.
If the title to any property which may affect the location of the Compliance Boundary is
changed, the permittee shall notify the Division Director within 14 days. The Director shall
then establish a modified Compliance Boundary which will be done as a modification to the
Permit.
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 REVIE
BOUNDARY, as determined by monitoring, the permittee shall ie ther (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; 9rr,
(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.
