Step-by-step explanation:
When there is a change of Person in Charge (PIC), the Bureau of Prisons (BOP) must be notified of the change. The specific timeframe for this notification can vary depending on the regulations of the institution and jurisdiction, but it is typically required to be done promptly to ensure compliance and maintain operational integrity. Immediate notification is generally advised to avoid any disruptions in communication or responsibilities that could impact the institution's functioning.
