This permit shall be effective from the date of issuance until December 31, 2004, shall void Permit No.
WQ0009267 issued March 27, 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, _Vor 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 (Division), such as the construction of additional or replacement wastewater
treatment and disposal facilities.
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 residuals generated from these treatment facilities must be disposed in accordance with General
Statute 143-215.1 and in a manner approved by the Division.
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) 50 feet between wetted area and any interceptor drains and/or surface water diversions (both upslope
and downslope),
e) 50 feet between wetted area and any groundwater lowering and surface drainage ditch as well as any
other stream, canal, marsh or coastal waters
f) 50 feet between wetted area and public right of ways,
g) 100 feet between wastewater treatment units and wells, and
h) 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.
11. OPERATION AND MAINTENANCE REQUIREMENTS

(E) Another method with prior approval by the Groundwater Section Chief
Any method used must meet the following qualifications:
(1) A laboratory must be DWQ certified to run any method used.
(2) The method used must, at a minimum, include all the constituents listed in Table VIII of
Standard Method 6230D.
(3) The method used must provided a PQL at 0.5 ug(L or less which must be supported by
laboratory proficiency studies as required by the DWQ Laboratory Certification Unit.
Any constituents detected above the MDL but below the PQL at 0.5 ug/L must be qualified
(estimated) and reported.
If any volatile organic compounds are detected by the methods listed, then the Wilmington Regional
Office Groundwater Supervisor, telephone number 910-395-3900, 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 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.
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.

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 Uni*
1636 Mail Service Center, Raleigh, North Carolina 27699-1636 on -or before the last working day
the month following the sampling month.

elevation of the measuring point for each monitoring well.
4. Within sixty (60) days of permit issuance, 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. The surveyor shall
establish a horizontal control monument on the property of the waste disposal system and determine
the latitude and longitude of this horizontal control monument to a horizontal positional accuracy of
+/- 10 feet. All other features listed in a. through e, above shall be surveyed relative to this
horizontal control monument. The positional accuracy of features listed in a, through e. above shall
have a ratio of precision not to exceed an error of closure of 1 foot per 10,000 feet of perimeter of t
survey. Any features located by the radial method will be located from a minimum of two points.
Horizontal control monument shall be installed in such a manner and made of such materials that
the monument will not be destroyed due to activities that may take place on the property. The map
shall also be surveyed using the North American Datum of 1983 coordinate system and shall indicate
the datum on the map. All bearings or azimuths shall be based on either the true or NAD 83 grid
meridian. If a Global Positioning System (GPS) is used to determine the latitude and longitude of
the horizontal control monument, a GPS receiver that has the capability to perform differential GPS
shall be used and all data collected by the GPS receiver will be differentially corrected.
The maps and any supporting documentation shall be sent to the Permits and Compliance Unit,
Groundwater Section,1636 Mail Service Center, Raleigh, NC, 27699-1636.

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 exceedarn
of standards at the Review Boundary shall require remediation action on the part of the permittee.
