characteristic, such as the dumping of the contents of a basin or tank, the known
passage of a slug of hazardous substance through the facility, or any other.unusual
circumstances;
b. Any process unit failure, due to known or unknown reasons, that renders the
groundwater treatment and disposal system incapable of adequate treatment and
disposal, such as mechanical or electrical failures of pumps, aerators, compressors,
etc.;
2

c. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-pass
directly to receiving waters without treatment of all or any portion of the influent to
such station or facility; or
d. Anytime that self-monitoring information indicates that the groundwater treatment and
disposal system is not in compliance with any specified permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in Ietter
form within five (5) days following first knowledge of the occurrence. This report must
outline the actions taken or proposed to be taken to ensure that the problem does not recur.

following parameters:
Water Level
EPA Methods 601, 602, and 610
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.
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

infiltration gallery. If the treatment system fails to consistently achieve this standard,
additional treatment units or changes in operational methods, may be required.
8. Isoconcentration (lines connecting points of equal concentration) maps in both the vertical
and horizontal directions shall be developed using the September groundwater monitoring
data for benzene. A water level contour map must also be developed on a yearly basis.
Two copies of these maps shall be submitted along with all other monitoring data for that
period to the Groundwater Section, NC Division of Water Quality, P.O. Box 29578

for the disposal system constructed after December 31, 1983 is established at either (1) 250
feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is
closest to the waste disposal area. An exceedance of Groundwater Quality Standards at or
beyond the Compliance Boundary is subject to immediate remediation action in addition to
the penalty provisions applicable under General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the
