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 Washington Regional Office, telephone
number 919/ 946-6481 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;
b. Any process unit failure, due to known or unknown reasons, that renders 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
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 facility is not in compliance
with its permit limitations.
