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
