Gas pipeline operators must reconfirm pressure limits more often, in more places

US pipeline regulators are correcting rules for how gas transmission lines confirm their maximum operating pressure. This means operators will need to re-evaluate more pipelines, more frequently, to ensure they are safe.

For years, some gas pipelines could operate without regularly reconfirming their pressure limits, especially older lines or those in less populated areas. This correction closes some of those loopholes. It means operators will have to spend more money on inspections and maintenance for a wider range of their infrastructure.
