of Water and Wastewater", 17th ed., 1989.

,
Method 2: Method 502.2 "Methods For The Determination of Organic Compounds in
Drinking Water", U.S. EPA - 600/4-88/039.
The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring 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
groundwater for the various analytical parameters, as specified in 15 NCAC 2L
[Groundwater Classifications and Standards]. Unless otherwise specified, the units for
these concentrations are expressed as milligrams per liter.
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/1, 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 EPA methods 604 and 611 must also be run to detect other organic compounds
which may be present. The results of all analyses 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
May, September, and January.
3. The Compliance Boundary delineated on the attached site map for the disposal system is
specified by regulations in 15A NCAC 2L, Groundwater Classifications and Standards.
An exceedance of Groundwater Quality Standards beyond the Compliance Boundary is
subject to the penalty provisions applicable under General Statute143-215.6(1)a. The sale
of property, by the Permittee, which is within or contiguous to the disposal site, may alter
the location of the Compliance Boundary.
For facilities permitted prior to December 30, 1983, the Compliance Boundary is
established at the lesser of 500 feet from the rotary distributors, or the property boundary,
whichever is less.
If the title to any property which may affect the location of the Compliance Boundary is
changed, the Permittee shall notify the DEM 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 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,
( ) 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.
4. Any additional groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
V . INSPECTIONS
l . Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
