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.
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.
IV. GROUNDWATER REQUIREMENTS
Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
2. Within 90 days of permit issuance, existing monitor well No. 1 shall be properly
abandoned according to procedures outlined in 15 NCAC 2C {Well Construction
Standards).
3. Within 90 days of permit issuance, one downgradient monitor well shall be installed
in the vicinity of existing monitor well No. 1 (to be abandoned) to monitor
groundwater quality. The location and construction details for these wells must be
approved by the Wilmington Regional Office, from which a well construction
permit must be obtained.
3. The new monitor well must be sampled initially after construction (and prior to waste
disposal operations) and thereafter every March, July, and November for the
following parameters:
NO3 (10.0)
Ammonia Nitrogen
TDS (500.0)
pH (6.5-8.5 standard units)
TOC
Water Level
Chloride (250.0)
Total Coliforms
NO2 (1.0)
TOX (in November only)
Orthophosphate
The measurement of water level must be made prior to sampling for the remaining
parameters.
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.
5

... .. .......—L%s .ACM
The analytical methods used for TOX must be capable of detecting the total of all
halogenated organic compounds present at a concentration of 5.0 parts per billion
(ppb) or greater. In the event that a TOX concentration of 5.0 ppb or greater is
detected, any individual halogenated organic compound(s) present at a concentration
at or above the method detection limit (MDL) must be identified and quantified
utilizing EPA methods 601, 602, 604, and 611.
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 backjLmnd 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 N,C. Division of
Environmental Management on Form GW-59 (Compliance Monitoring Report
Form) every April, August, and December.
The Compliance Boundary 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 prior to December 30, 1983, the Compliance Boundary is
established at a distance 500 feet from the low pressure subsurface disposal field, 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 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 VIEW 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.
V. INSPECTIONS
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
A

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
