hours or on the next working day following the occurrence or first knowledge of the
occurrence of any of the following:
a. Any occurrence at the wastewater treatment facility which results in the
treatment of significant amounts of wastes which are abnormal in quantity or
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 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 directly to receiving waters without treatment 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 reoccur.

2. After thirty (30) days of operation, and thereafter in March, July and October a
sample of the effluent immediately prior to discharge into the nitrification field (either
at the effluent end of the septic tank or at the distribution box, if accessible) shall be
taken and analyzed for the following parameters:
NO3 (10.0) MBAS
Ammonia Nitrogen Orthophosphate
pH (6.5-8.5 standard Units) Sodium
TOC
Volatile Organic Compounds - in October only (by Method I or 2 below)
Method 1 ; Method 6230D (Capillary -Column), "Standard Methods For
the Examination 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 - 60014-881039
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.
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 background 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.
The results of the sampling and analysis shall be sent to the NC Division of
Environmental Management, Groundwater Section, Mooresville Regional Office, by
the end of the month which follows the month in which the samples were obtained
(i.e. analyses for samples taken in March should be submitted by the end of April).
Based upon subsequent review of the effluent analytical data, monitoring wells may
be required in order to monitor groundwater quality.
