3. 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rescinded unless the facilities are installed, maintained, and operated in a manner which will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.
4. 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.
6. 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.
7. Diversion or bypassing of the untreated groundwater from the treatment facilities is prohibited.
II. OPERATION AND MAINTENANCE REQUIREMENTS

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 ll, 1II, and IV facility at least daily, excluding weekends and

will be established and an acceptable sampling reporting schedule shall be followed.
2. Noncompliance Notification:
The Permittee shall report by telephone to the Winston-Salem Regional Office, telephone number
336-771-4600, 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;
2

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 limitations.
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.
IV. GROUNDWATER REQUIREMENTS
