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 recur.
IV. GROUNDWATER REQUIREMENTS_
Prior to beginning waste disposal operations at the new disposal fields, 5 new
monitor wells, shall be installed to monitor groundwater quality. The wells shall be
constructed such that the water level in the well is never above or below the screened
(open) portion of the well at any time during the year. 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.
5

2. All monitor wells must be sampled initially after construction and thereafter every
April, August and December for the following parameters:
NO3 (10.0) Ammonia Nitrogen
TDS (500.0) TOC
pH (6.5-8.5 standard units) Chloride (250.0)
Total Coliforms (1/100m1) Water Level
Orthophosphate
Volatile Organic Compounds - In December Only (By method 1 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 "Method For The Determination Of Organic Compounds
In Drinking Water", U.S. EPA - 600/4-88/039
The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (top of well casing) of all new monitoring wells shall be
surveyed relative to mean sea level (M.S.L.). The depth of water in each well shall
be measured from the surveyed point on the top of the casing. The water level
elevations shall then be determined relative to M.S.L.
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 mullion.
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 backgrognd 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.
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.
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.
3. 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 on or after December 30, 1983, (new fields 1,2,3, and 4) the
Compliance Boundary is established at the lesser of 250 feet from the perimeter of
the subsurface disposal fields, or 50 feet within the property boundary.
For facilities permitted before December 30, 1983, (existing fields 2,3, and 4) the
Compliance Boundary is established at a distance 500 feet from the disposal fields,
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 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.
4. Monitoring wells designated to be abandoned shall be abandoned in accordance with
15A NCAC 2C (Well Construction Standards).
5. Line sinks (drainage ditches) shall be constructed on the northern and western
portions of the new disposal fields as recommended by Russnow, Kane and
Andrews.
6. Any additional groundwater quality monitoring, as deemed necessary by the
Division, shall be provided.
V. INSPECTIONS
l . 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.
