be rescinded unless the facilities are installed, maintained, and operated in a manner which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.
2. 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 as
may be required by this Division, such as the construction of additional or replacement
treatment or disposal facilities.
3. 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 sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.

5. Diversion or bypassing of the untreated groundwater from the treatment facilities is
prohibited.
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 Certification Commission, 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 Certification Commission. The Permittee must also employ a
certified back-up operator of the appropriate type and grade to comply with the conditions
of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class H, 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 Title 15A, Chapter 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 REVOSTING „REQUIREMENTS
Any monitoring deemed necessary by the Division of Environmental Management 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 Winston-Salem Regional Office, telephone
number [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
sigrificant 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.

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. Due to the possibility of generating chlorinated halocarbons, the permittee shall not
construct a chlorinator for disinfection. Instead an alternate means of disinfection should
be pursued if it is deemed necessary by the permittee.
2. Due to the fact that placement of the infiltration gallery may result in migration of
contaminants away from the recovery system, the permittee shall install carbon adsorption
to the treatment process to further decrease the levels of contaminants in the effluent.
