7. Noncompliance Notification:
The Permittee shall report by telephone to the Wilmington Regional Office,
telephone no. [phone], 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.
1. Within 90 days of permit issuance, four (4) monitor wells, one (1) upgradient and
three (3) downgradient, must be installed to monitor groundwater quality. The
wells shall be constructed such that the water level is never above or below the
screened (open) portion of the well at any time during the well. 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.
2. The monitor wells must be sampled initially after construction (and prior to waste
disposal operations) and thereafter every March, July, and November for the
following parameters:
NOS (10.0) `IDS (500.0)
TOC pH ( 6.5-8.5 standard units)
Ammonia Nitrogen Chlorides (250.0)
Water Level Total Coliforms (1/100 ml)
SO4(250.0)
Volatile Organic Compounds - In November 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 -
600/4-88/039
The measurement of water level must be made pilar to sampling fog the remain;n
parameters.
AUG p9

The measuring points (top of well casing) of all monitoring wells shall be
surveyed relative to mean sea level (M.S.L.). The depth of the 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 million.
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 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.
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 April, August, and December.
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, the Compliance Boundary is
established at the lesser of 250 feet from the perimeter of the waste disposal area, 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-cgAdAU>i!4l�ejlilx
design or operational controls that will prevent a violationadd � tat;t e 1
Compliance Boundary, and implement that plan upon its appro �Is�b'y the Director.'F= {;1

4. Any additional groundwater quality monitoring as deemed necessary by the Division
shall be provided.
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 Pen- ittee 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.
