PHMSA's regulations include two methods for operators to submit notifications.

Operators should provide pertinent information about the reason for the notification and the pipeline system, or systems, relevant to the notification. Operators are reminded that PHMSA regulations require operators to provide certain notifications to State pipeline safety agencies.
