The Permittee shall report by telephone to the Raleigh Regional Office, telephone
no. 919/ 733-2314, 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.
3

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 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.
1. The three (3) existing monitor wells must be sampled every March, July, and
November for the following parameters:
NO3 (10.0)
TOC
Ammonia Nitrogen
Water Level
Total Suspended Solids
Volatile Organic Compounds -
TDS (500.0)
pH ( 6.5-8.5 standard units)
Chloride (250.0)
Fecal Coliforms (1/100 ml)
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 - 600/488/039
The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (top of well casing) of all monitoring wells shall be
surveyed to provide relative elevations of the measuring point for each of the
monitoring wells. The depth of water in each well shall be measured from the
surveyed point on the top of the casing.
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.
12

If any volatile organic compounds are detected by method 6230D, or the equivalent
method 502.2, then EPA methods 504 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.
2. The m li n BgUndgy,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 143-215.6A. The sale of
property, by the Permittee, which is within or contiguous to the disposal system
site may alter the 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 subsurface disposal system, 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 delineated on the attached site map for the disposal
system is specified by regulations in 15 NCAC 2L, Groundwater Classifications
and Standards. A REVMVy BOJ]NDARY 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, 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.
3. Any additional groundwater quality monitoring as deemed necessary by the Division
of Environmental Management shall be provided.
1. 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.
1-0

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.
1. This permit shall become voidable unless the facilities are constructed in accordance
with the conditions of this permit, the approved plans, specifications and other
supporting data.
2. This permit is effective only with respect to the nature and volume of wastes
described in the application and other supporting data.
3. This permit is not transferable. In the event there is desire for the facilities to
change ownership, or there is a name change of the Permittee, a formai permit
request must be submitted to the Division of Environmental Management
accompanied by an application fee, documentation from the parties involved, and
other supporting materials as may be appropriate. The approval of this request will
be considered on its merits and may or may not be approved.
4. Prior to any transfer of this land, a notice shall be given to the new owner that gives
full details of the materials applied or incorporated at this site.
5. A set of approved plans and specifications for the subject project must be retained
by the applicant for the life of the project, if available upon issuance of this permit
6. The annual administering and compliance fee must be paid by the Permittee within
thirty (30) days after being billed by the Division. Failure to pay the fee
accordingly may cause the Division to initiate action to revoke this permit as
specified by 15A NCAC 2H.0205 (c)(4).
7. Failure to abide by the conditions and limitations contained in this permit may
subject the Permittee to an enforcement action by the Division of Environmental
Management in accordance with North Carolina General Statute 143-215.6A to
143-215.6C.
S. The subject wastewater treatment and disposal facilities shall be connected to an
operational publicly owned wastewater collection system within 180 days of its
availability to the subject facilities, if the subject wastewater treatment or disposal
facilities are in noncompliance with the terms and conditions of this non -discharge
permit or the governing statutes or regulations.
Prior to the initiation of these connection activities, appropriate approval must be
received from this Division.
9. The issuance of this permit does not preclude the Permittee from complying with
any and all statutes, rules, regulations, or ordinances which may be imposed by
other government agencies (local, state, and federal) which have jurisdiction.
��

10. The Permittee, at least six (b) months prior to the expiration of this permit, shall
request its extension. Upon receipt of the request, the Commission will review the
adequacy of the facilities described therein, and if warranted, will extend the permit
for such period of time and under such conditions and limitations as it may deem
appropriate_
