The debarring official may debar a person for any of the causes in
Sec. 98.305, using procedures established in Secs. 98.310 through
98.314. The existence of a cause for debarment, however, does not
necessarily require that the person be debarred; the seriousness of the
person's acts or omissions and any mitigating factors shall be
considered in making any debarment decision.
