at least forty-eight (48) hours in advance of operation of the installed facilities so that
an in -place inspection can be made. Such notification to the regional supervisor shall
be made during the normal office hours from 8:00 a.m. until 5.00 p.m. on Monday
through Friday, excluding State Holidays.
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, 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

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.
8. The system must be operated to prevent bottom solids accumulations in the storage
cell of the existing treatment lagoon which could carry-over of settled solids to the
storage lagoon, and no appreciable accumulations of settled solids in the storage
lagoon.

the 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, P.O. Box 29578, Raleigh, NC, 27626-0578,

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.
8. If any volatile organic compounds are detected by the methods listed, then the Yy)q4
Regional Office Groundwater Supervisor, telephone number *)WY, 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.
9. 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.

10. 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.
11. 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
