The notification generation logic will always select the highest ranked notification that matches the criteria of the entity to which the notification relates (e.g. program area, entity type, etc).
Imagine three scenarios:
Submission Status Change Notification - Program Area = (none) , Action Type filters = (none) (generic) - Priority = 3
Submission Status Change Notification - Program Area = "Resources", Action Type filter = (none) (more specific) - Priority = 2
Submission Status Change Notification - Program Area = "Resources", Action Type filter = "Renewal" (very specific) - Priority = 1
So if a submission's status changes for a Resources permit whose Action Type = "New" then #2 will be sent since it does not meet the criteria of #3. So if a submission's status changes for a NPDES permit then #1 will be sent since it does not meet the criteria of #2 or #3
