This permit shall be effective from the date of issuance until April 30, 2000, shall void Permit No.
WQ0001817 issued February 13, 1990, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. Prior to spray irrigation to the 65.61 acres of spray field, the field must be regraded and
reseeded and all of the spray nozzles must be checked and repaired (if needed). These
activities shall be approved by the Washington Regional Office.
2. Prior to spray irrigation the chlorinator and flow measurement device shall be connected to
the system.

3 . 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
Environmental Management, such as the construction of additional or replacement
wastewater treatment and disposal facilities.
4. 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.
5. 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 North Carolina Division of
Environmental Management.
6. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
7. 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 aiea 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,
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
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

and MW-8) shall be sampled every April, August and November for the following
parameters:
NO3 Ammonia Nitrogen
TDS TOC
pH Water Level
Chloride Fecal Coliforms
Volatile Organic Compounds - In November only (by Method 1 or 2 below)
Method 1: Method 6230D (Capillary - Column), "Standard Methods For The
Examination of Water and Wastewater", 17th ed., 1989
Method 2: Method 502.2 "Methods For The Determination Of Organic Compounds

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/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/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 the Washington 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 shall be sent to the Groundwater Section, Permits
and Compliance Unit, P.O. Box 29535 Raleigh, N.C. 27626-0535 on Form GW-59

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.
4. Within sixty (60) days of completion of all monitoring wells, the Permittee shall submit
two original copies of a scaled topographic map (scale no greater than 1":100') signed and
sealed by a professional engineer or a state licensed land surveyor that indicates all of the
following information:
a. the location and identity of each monitoring well,
b. the location of the waste disposal system,
c. the location of all property boundaries,
d. the latitude and longitude of the established horizontal control monument,
e. the relative elevation of the top of the well casing (which shall be known as the
"measuring point"), and
f. the depth of water below the measuring point at the time the measuring point is
established.

The survey shall be conducted using approved practices outlined in North Carolina General
Statutes Chapter 89C and the North Carolina Administrative Code Title 21, Chapter 56.
