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 [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 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 limitations.
