El

The measurement of water level must be made prior to sampling for the remaining
parameters.
The measurin1.71
g points (top of well casing) of all monitoring wells shall be surveyed to
provide relative elevations of the measuring point for each of the monitoring wells. The
depth of water in each well shall be measured from the surveyed point on the top of the
casing.
The numbers in parentheses represent the maximum allowable concentrations in
L[Gro,roundwater for the various analytical parameters, as specified in 15 NCAC fl-
[Groundwater
undwater Classifications and Standards]. Unless otherwise noted, the concentrations
are expressed as milligrams per liter.
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 TQC 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 TQC 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 EPA methods 604 and 511 must also be run to detect other organic compounds
which may be present. The results of all analysis specified in the monitoring requirements,
including 604 and 611 if required, must be submitted simultaneously
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management on Form GW -59 (Compliance Monitoring Report Form) every
April, August, and December.
4. The Compliance Boundary delineated on the attached site plan for the disposal system is
specified by regulations in 15 NCAC 2L, Classifications and Water Quality Standards
applicable to the groundwater of North Carolina. An exceedance of Groundwater Quality
Standards beyond the Compliance Boundary is subject to penalty provisions applicable
under General Statute 143-215.6(1)x. The sale of property, by the Permittee, which is
within or contiguous to the disposal system site may alter location of the Compliance
Boundary.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the subsurface disposal fields, or 50 feet within
the property boundary.
If the title to any property which may affect the location of the Compliance Boundary is
changed, the permittee shall notify the Division Director within 14 days. The Director shall
then establish a modified Compliance Boundary which will be. done as a modification to the
Permit.
The REVIEW BOUNDARY delineated on the attached site plan for the disposal system is
specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. A
REVIEW BOUNDARY is established around disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. When the
concentration of any substance equals or exceeds the maximum allowable concentration of
that substance at the REVIEW BOUNDARY, as determined by monitoring, the permittee
shall either (i) demonstrate, through predictive calculations or modeling, that natural site
conditions, facility design and operational controls will prevent a violation of standards at
the Compliance Boundary; or, (ii) submit a plan for the alteration of existing site
conditions, facility design or operational controls that will prevent a violation of standards
at the Compliance Boundary, and implement that plan upon its approval by the Director.
