Pipeline operators get more time to install automatic shut-off valves
What happened
The US pipeline safety agency proposes to give pipeline operators more time to install automatic shut-off valves. This means companies will have longer to comply with a rule meant to reduce damage from pipeline ruptures.
Why it matters
Automatic shut-off valves, called rupture-mitigation valves, are designed to stop the flow of gas or liquid quickly after a pipeline breaks. This reduces the amount of material spilled and the potential for explosions. Giving operators more time to install these valves means the safety benefits will take longer to materialize across the pipeline network.
The signal
Watch for the final rule to see if the extended timeframes are adopted as proposed, or if public comments push for a shorter deadline.
