Some of the buffers specified above may not have been included in previous permits for this waste
treatment and disposal system. These buffers are not intended to prohibit or prevent modifications,
which are required by the Division, to improve performance of the existing treatment facility. These
buffers do, however, apply to modifications of the treatment and disposal facilities, which are for the
purpose of increasing the flow that is tributary to the facility. These buffers do apply to any
expansion or modification of the infiltration areas and apply in instances in which the sale of property
would cause any of the buffers now complied with, for the treatment and disposal facilities, to be
violated. The applicant is advised that any modifications to the existing facilities will require a permit
modification.

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 sludge digester; the known passage of a slug of hazardous substance through the
facility; or any other unusual circumstances including ponding in the irrigation field or runoff
from the irrigation fields.
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 disposal system resulting in a by-pass directly to receiving waters.
d. Any time that self-monitoring information indicates that the facility has gone out of compliance
with its permit limitations including, but not limited to, freeboard measurements, effluent
limitations, exceedances of groundwater standards, or overloading of any field.
For any emergency that requires immediate reporting (e.g., discharges to surface waters, imminent
failure of a storage structure, etc.) outside normal business hours must be reported to the Division's
Emergency Response personnel at telephone number [phone], [phone], or (919) 733-
3300. Persons reporting such occurrences by telephone shall also file a written report in letter form
within five (5) 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.
V. INSPECTIONS
1. Adequate inspection and maintenance shall be provided by the Permittee to ensure proper operation
of the subject facilities.
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 five years from the date of the inspection and shall be
made available upon request to the Division or other permitting authority.

3. Any duly authorized officer, employee, or representative of the Division may, upon presentation of
credentials, enter and inspect any property, premises or place on or related to the disposal site or
facility at any reasonable time for the purpose of determining compliance with this permit; may
inspect or copy any records that must be maintained under the terms and conditions of this permit,
and may obtain samples of groundwater, surface water, or leachate.
VI. GENERAL CONDITIONS
Failure to abide by the conditions and limitations contained in this permit may subject the Permittee
to V enforcement action by the Division in accordance with North Carolina General Statute 143-
215.6A to 143-215.6C.
2. This permit shall become voidable unless the facilities are constructed in accordance with the
conditions of this permit, the approved plans and specifications, and other supporting data.
This permit is effective only with respect to the nature and volume of wastes described in the
application and other supporting data. No variances to applicable rules governing the construction
and / or operation of the permitted facilities are granted unless specifically requested and granted in
this permit.
4. The Division accepts the data -based design flow rate of 237 gallons per day per residential unit
(gpdpRU) for the community served by this system. Regardless of the adjusted design daily
wastewater flow rate, at no time shall the wastewater flows exceed the limits defined in this permit
for the subject facility or exceed the capacity of the sewers downstream of any new sewer extension
or service connection(s).
The Permittee shall report the actual (measured) monthly average amount of wastewater flow
contributed per unit (gpdpRU) for the 12 months prior to renewal. If any of these values are within
20% OF THE APPROVED VALUES, the permittee shall re-evaluate the approved value using the
methodology used to determine the approved flow rate of 237 gpdpRU and submit this information
within eighteen months of renewal. The Division may change the design flow rate for connections to
the system at that time, and upon each renewal cycle, pending an evaluation of the submitted flow
information.
The issuance of this permit does not exempt 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) that have jurisdiction. Of particular concern to the Division are applicable river buffer
rules in 15A NCAC 02B .0200, erosion and sedimentation control requirements in 15A NCAC
Chapter 4 and under the Division's General Permit NCGO10000, and any requirements pertaining to
wetlands under 15A NCAC 02B .0200 and 02H .0500.
6. In the event there is a desire for the facilities to change ownership, or there is a name change of the
Permittee, a formal permit request must be submitted to the Division on official Division form(s),
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. The
Permittee of record shall remain fully responsible for compliance until a permit is issued to the new
owner.
7. The Permittee shall retain a set of approved plans and specifications for the life of the facilities
permitted herein.
The Permittee shall maintain this permit until all permitted facilities herein are properly closed or
permitted under another permit issued by the appropriate permitting authority.
