7. For the initial sampling of the well as specified elsewhere in the permit, the permittee shall
submit a copy of the GW-1 Form (Well Completion Form) with the Compliance
Monitoring Form (GW-59) for that well. Compliance Monitoring Forms that do not
include copies of the GW-1 form will be returned to the permittee without being processed.
Failure to submit these forms as required by this permit may result in the initiation of
enforcement activities pursuant to NC General Statutes 143-215.6.
8. Monitor wells MW-1, MW-2, MW-3, MW-4, and MW-5, shall be sampled initially after
construction (and prior to waste disposal operations) and thereafter every February, rune,
and October for the following parameters:
TOC Water Level
pH TDS
TS S Cl
Total Phosphorous NO2
NO3 NH3
Method 6230D - In October only
Method 6230D (Capillary - Column), "Standard Methods For The Examination of
Water and Wastewater", 17th ed., 1989
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 mg/l 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 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.

and Compliance Unit, P.O. Box 29578 Raleigh, N.C. 27626-0578 on Form GW-59
[Compliance Monitoring Report Form] every March, July, and November.
9. The water levels in Monitor Wells MWA, MW-2, and MW-3 shall be measured once each
week for the first two months of waste disposal operations. Water levels shall be taken in
these three wells monthly thereafter.
The water level measurements shall be converted to equivalent MSL elevations and the
necessary calculations performed to ascertain the depth of the water table beneath the
surface of the ground at the respective location of each monitor well. This information
shall be kept at the site at all time and also sent to the groundwater supervisor at the
Wilmington Regional Office every month.
10. No land application of waste activities shall be undertaken when the seasonal high water
table is less than three feet below land surface.
11. Any exceedance of the Groundwater Standards at or beyond the Review Boundary, as
specified by the regulations in 15A NCAC 2L, Groundwater Classifications and Standards,
as detected during the monitoring which will be performed after the initial sampling of
Monitoring Wells MW-4 and MW-5, will mandate the institution of a Corrective Action in
accordance with 15A NCAC 2L .0106. Such action may include the installation of a liner
along the interior surfaces of the proposed irrigation pond. If this is implemented by the
Permittee, the interior surfaces of the irrigation pond shall be lined with a synthetic material
of sufficient thickness to exhibit structural integrity and a hydraulic conductivity of no
greater than 1 x 10-6 cm/sec. Following installation and inspection of the lagoon liner, and
prior to waste disposal operations, verification of the liner's compliance with hydraulic
conductivity and thickness specifications must be provided to the Division of
Environmental Management, Groundwater Section, by the project engineer.
12. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
13. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
