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 December 31, 1997, shall void Permit
No. 7036R issued March 14, 1988 and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. Upon completion of the mansonary wall, a certification must be received from a
professional engineer certifying that the permitted facility has been installed in accordance
with this permit, the approved plans and specifications. Mail the Certification to the
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
2. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action to correct the
problem, including actions as may be required by this Division, such as the construction of
additional or replacement wastewater treatment or disposal facilities.
3. This permit shall Become voidable if the soils fail to adequately absorb 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be rescinded unless the facilities are installed, maintained, and operated in a manner which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.
Ponding of wastewater on the surface of the distribution field when the dosing cycle
commences shall be considered evidence of failure of the soils to adequately absorb the
wastewater. Additionally, such failure shall be interpreted as a violation of this permit
condition.
4. 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.
5. Adequate measures shall be taken to divert stormwater from the high rate infiltration area
and to prevent wastewater runoff.
6. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
7. 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.
8. The following buffers shall be maintained:
a) 500 feet between high rate infiltration unit and any public works surface supply or
public shallow potable water well.
b) 100 feet between high rate infiltration unit and any "SA" classified surface waters.
c) 50 feet between high rate infiltration unit and any other surface waters.
d) 100 feet between high rate infiltration unit and property lines.
e) 50 feet between treatment units and property lines.
f) 50 feet between high rate infiltration unit and other treatment units and public right
of ways.
g) 200 feet between high rate infiltration unit and surface or groundwater drainage
systems.
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.
9. 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 15 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.
10. A fixed mansonry wall shall be constructed around each rotary distributor within 120 days
after issuance of this permit.

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 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. The facilities shall be effectively maintained and operated as a non -discharge system to
prevent the discharge of any wastewater outside the high rate infiltration disposal area
resulting from the operation of this facility.
4. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
5. The rotary distribution fields shall be raked twice weekly during the months April to
October, and once a week during the months of November to March.
6. The screenings removed from the wastewater treatment plant shall be properly disposed of
in a sanitary landfill.
7. The distribution field(s) shall be kept free of vegetation at all times. There shall be no rotor
tillers used on the rotary distribution field(s). Vegetation must be removed from the field(s)
manually.
8. The application of chemicals to the distribution field(s) is expressly prohibited.

1. Within 90 days of permit issuance one (1) downgradient monitor well shall be installed to
monitor groundwater quality. The well shall be constructed such that the water level in the
well is never above or below the screened (open) portion of the well at any time during the
year. However, the exact location and construction details for these wells shall be
approved by the Wilmington Regional Office, from which a well construction permit must
be obtained.
2. The monitor wells shall be sampled initially after construction and thereafter every March,
July, and November for the following parameters:
NO3
TOC
Ammonia Nitrogen
Water Level
Total Suspended Solids
Volatile Organic Compounds -
TDS
pH
Chloride

The measurement of water level must be made prior to sampling for the remaining
parameters.
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 well. These
elevations shall be provided to the Regioal Hydrogeologist within 60 days after well
construction. The depth of water in each well shall be measured from the surveyed point
on the top of the casing.
If TOC concentrations greater than 10 mg/1 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/1, 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 on Form GW-59 (Compliance Monitoring Report Form) every
April, August and December.

3. The Compliance Boundary delineated on the attached site plan for the disposal system is
specified by regulations in 15 NCAC 2L, Classifications and Water Quality Standards
applicable to the groundwater of North Carolina. An exceedance of Groundwater Quality
Standards beyond the Compliance 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 rotary distributors 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 BQ.INDARY for the disposal system is specified by regulations in 15
NCAC 2L, Groundwater Classifications and Standards. A IEW BQUNDARY 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 RE V IE W
BQUNDARY, as determined by monitoring, the permittee shall either (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.
4, 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.
