of Environment, Health and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until August 31, 2000, shall void Permit
No. WQ0003396 issued August 31, 1995, 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 assimilate the wastewater, the Permittee shall take immediate
corrective actions including those actions that may be required by the Division of Water
Quality, such as the construction of additional or replacement wastewater treatment and
disposal facilities.

2. The issuance of this pem-iit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
3. The residuals 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 Water Quality.
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 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
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. A suitable vegetative cover shall be maintained.
4. Irrigation shall not be performed daring 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.

such station or facility; or
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 five (5) 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. GROUNDWATER REQUIREMENTS
1. Monitor wells SMW-3, SMW-4, SMW-5, SMW-8, SMW-9 and SMW-18 shall be
sampled every March, July and November for the following parameters:
NO3 Ammonia Nitrogen
TDS TOC
pH Water Level
Chloride Orthophosphate
Formaldehyde - In November Only
Volatile Organic Compounds - In November only by the method below
Method 6230D (Capillary - Column), "Standard Methods For The Examination of
Water and Wastewater", 17th ed., 1989
4

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 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 mg1l 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, then the Raleigh
Regional Office Groundwater Supervisor, telephone number [phone], must be
contacted immediately for further instructions regarding any additional follow-up analyses
required. The results of all initial and follow-up analyses must be submitted
simultaneously.
The results of the sampling and analysis must be received on Form GW-59 (Groundwater
Quality Monitoring: Compliance Report Form) by the Groundwater Section, Permits and
Compliance Unit, P.O. Box 29578 Raleigh, N.C. 27626-0578 on or before the last
working day of the month following the sampling month.
2. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is
for the disposal system constructed after December 31, 1983 is established at either (1) 250
feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is
closest to the waste disposal area. An exceedance of Groundwater Quality Standards at or
beyond the Compliance 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.
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 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 period
