Federal Waivers

In circumstances where absolute compliance with a pipeline safety regulation would not be appropriate and where sufficient alternative safeguards to the public safety are implemented, PHMSA, at it discretion, may grant an operator's petition for a waiver from the regulations applicable to interstate pipeline transportation.

State Waivers

A state agency certified under Natural Gas Pipeline Safety Act (NGPSA) or Hazardous Liquid Pipeline Safety Act (HLPSA) may waive compliance with a safety regulation applicable to intrastate pipeline transportation if, after receiving notice, PHMSA concurs in the action.
