5. Noncompliance Notification:
The Permittee shall report by telephone to the Washington Regional Office as soon
as possible, but in no case more than 24 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.
IV. GROUNDWATER REQUIREMENTS
1. Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
2. Prior to beginning waste disposal operations, six (6) monitor wells, one (1)
upgradient and five (5) downgradient, must be installed to monitor groundwater
quality. The location and construction details for these wells must be approved by
the Washington Regional Office, from which a well construction permit must be
obtained.
El

3. The monitor wells must be sampled initially after construction (and prior to waste
disposal operations) and thereafter every April, July, September and November for
the following parameters;
NO3 Ammonia Nitrogen
TDS TOC
Total Coliforms pH
Chloride TOX (in November only)
Water Level
The measurement of water level must be made prior to sampling for the remaining
parameters. The measuring points for water levels on all wells shall be surveyed and
their elevation referenced to mean sea level, the measurements taken shall be accurate
to ± 0.01 feet.
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/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 and monitor well exceeds 10 mg/1, this concentration will
be taken to represent the naturally occurring TOC concentration. Any exceedances
of this naturally occurring TQC 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 May, August, October and December.
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 disposal fields, 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.
i

The REVIEW BOUNDARY for the disposal system is specified by regulations in 15
NCAC 2L, Groundwater CIassifications 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 BQUNDARY, as determined by monitoring, the Permittee shall
either (i) demonstrate, through predictive calculations or modeling, that natural site
conditions, facilit} 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. Prior to beginning waste disposal operations, any water wells (except monitor wells)
located within 200 feet of the subsurface disposal fields shall be abandoned in
accordance with requirements of 15 NCAC 2C (NC Well Construction Standards).
5. Any additional groundwater quality monitoring, as deemed necessary by this
Division, shall be provided.
V. INSPECTIQNS
I . 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.
3. Any duly authorized officer, employee, or representative of the Division of
Environmental Management may, upon presentation of credentials, enter and inspect
any property, premises or place on or related to the disposal site and facility at any
reasonable time for the purpose of determining compliance with this permit; may
inspect or copy any records that must be kept under the terms and conditions of this
permit; or may obtain samples of groundwater, surface water, or leachate.
