WQ0009910 issued December 27, 1994, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be
rescinded unless the facilities are installed, maintained, and operated in a manner which will
protect the assigned water quality standards of the surface waters and ground waters.
In the event that the facilities fail to perform satisfactorily, including the creation of nuisance
conditions, the Permittee shall take immediate corrective action, including those actions that may
be required by the Division of Water Quality (Division), such as the construction of additional or
replacement treatment or disposal facilities.
The issuance of this permit shall not relieve the Permittee of the responsibility for damages to
surface or groundwaters resulting from the operation of this facility.
4. Any residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the Division.

II. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Water Pollution Control Systems Operators Certification
Commission (WPCSOCC), the Permittee shall employ a certified wastewater treatment plant
operator to be in responsible charge (ORC) of the wastewater treatment facilities. The operator
must hold a certificate of the type and grade at least equivalent to or greater than the classification
assigned to the wastewater treatment facilities by the WPCSOCC. The Permittee must also
employ a certified back-up operator of the appropriate type and grade to comply with the
conditions of 15A NCAC 8A .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of 15A NCAC 8A .0202.
3. The facilities shall be effectively maintained and operated as a non -discharge system to prevent
the discharge of any wastewater resulting from the operation of this facility.
III. MONITORING AND REPORTING REQUIREMENTS
Any monitoring deemed necessary by the Division to insure surface and ground water protection
will be established and an acceptable sampling reporting schedule shall be followed.
2. Noncompliance Notification:
The Permittee shall report by telephone to the Raleigh Regional Office, telephone number 919-
571-4700, 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 groundwater remediation facility which results in the treatment of
significant amounts of contaminated groundwaters 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 renders the groundwater
treatment and disposal system incapable of adequate treatment and disposal, 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; or
d. Any time that self -monitoring information indicates that the groundwater treatment and
disposal system is not in compliance with any specified permit Iimitations.
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.

noncompliance with a permit condition of malfunction of the system which may cause fluid
migration outside the infiltration zone or area. The information shall be provided to the Raleigh
Regional Office orally within 8 hours of the occurrence and as a written submission within five
days of the occurrence. The written submission shall contain a description of the noncompliance
and its cause, the period of noncompliance, including exact dates and times, and if the
