IV. GROUND31ATER REQUIREMENTS
Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
2. The two (2) existing monitoring wells shall be sampled every November for the
following parameters:
Total Dissolved Solids (500.0)
Total Suspended Solids
PH (6.5-8.5 standard units)
Water Level
Volatile Organic Compounds - by Method 1 or Method 2 below
Method 1: Method 6230D ( Capillary - Column), "Standard Methods for the
Examination of Water and Wastewater", 17th edition, 1989
Method 2: Method 502.2 " Methods for the Determination of Organic
Compounds in Drinking Water", United States Environmental Protection
Agency - 60014-881039
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
hemonitoring 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 15A NCAC 2L
[Groundwater Classifications and Standards]. Unless otherwise noted, the
concentrations are expressed in parts per million.
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 analysis specified in
the monitoring requirements, including 604 and 611 if required, must be submitted
simultaneously.
4

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 December.
The Compliance Boundary 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
penalty provisions applicable under General Statute 143-215.6(1)a. The sale of
property, by the Permittee, which is within or contiguous to the disposal system
site may alter the location of the Compliance Boundary.
4. For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the subsurface disposal field, or 50 feet
within the property boundary.
5. 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.
6. The REyIEW BOUNDARY for the disposal system is specified by regulations in
15A 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 _BQUNDARY, 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.
7. Oil drained from engine crankcases, antifreeze, paint, or degreasing solvent wastes
shall not be discharged into the disposal system.
V. INSPECTIONS
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee
to insure proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal
facilities to prevent malfunctions and deterioration, operator errors and discharges
