Exigent Circumstances It will not be a violation of this MI if the Postal Service does not provide PAS to an employee for whom the RAC has approved PAS when such failure is due to an exigent circumstance. Exigent circumstances include, but are not limited, to the following: Cancellation or failure of a qualified PAS provider to appear as scheduled. Security breaches or acts of terrorism. Natural disasters. Actions or omissions by the employee that prevent PAS from being provided. Other incidents beyond the control of the Postal Service. The Postal Service will provide or restore any PAS required under this MI as soon as is reasonably possible after the exigent circumstance passes, after the effects of the exigent circumstance can reasonably be corrected by the Postal Service, or both, all as determined on a case-by-case basis.
