Narrative:

Aircraft X was an IFR departure with an edct (expect departure clearance time). The clearance was issued before I took the position. The pilots called ready for taxi ahead of their edct time and went to wait near the runway for the edct time. Once they were within the window to depart; local control coordinated the departure with pbi approach and it was accepted. After the aircraft departed pbi called to clear up if the aircraft was released due to a crash fire rescue equipment program to [destination] via certain routes on top of the edct. This is something I'm pretty sure I've never seen before and didn't even think to see if the aircraft had additional flow programs related to their flight with already having an edct in place. Pick one flow program or the other. Having to get a release defeats the whole purpose of having an edct time and can cause controllers to become focused on meeting the edct window and overlooking a crash fire rescue equipment effecting an aircraft like this situation caused.
