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 render the facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, aerators, compressors, etc.
c. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass of all or any portion of the influent to such station or facility.
d. Any time that self -monitoring information indicates that the facility has gone out of
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 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.
IV. GROUNDWATER REQUIREMENTS
1. The three (3) existing monitor wells shall be sampled every April, August, and December
for the following parameters:
NO3 (10.0) TDS (500.0)
TOC pH ( 6.5-8.5 standard units)
Ammonia Nitrogen Chloride (250.0)
Water Level Fecal Coliforms (1/100 ml)
NO2 Total Suspended Solids
Volatile Organic Compounds - In December only (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 - 600/4-
8 8/039
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 paint 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 noted, the concentrations
are given in parts per million.
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 back round 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.
I.l

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
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.
2. 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)a. 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 perimeter of waste disposal 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 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.
Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
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 which may cause
or lead to the release of wastes to the environment, a threat to human health, or a nuisance.
The Permittee shall keep an inspection log or summary including at least the date and time
of inspection, observations made, and any maintenance, repairs, or corrective actions
taken by the Permittee. This log of inspections shall be maintained by the Permittee for a
period of three years from the date of the inspection and shall be made available upon
request to the Division of Environmental Management or other permitting authority.
5
