Pipeline Pathways

PG&E's top priority is the public safety of our customers and our employees. We are taking steps every day to strengthen our natural gas transmission pipeline system and become the nation’s safest and most reliable gas utility.

As part of this commitment to safety, PG&E is checking the area above our 6,750-mile natural gas transmission pipeline system and working cooperatively with cities, neighborhoods and property owners to enhance safety by reducing risks to the integrity of the pipeline and improving access for PG&E to do safety work. This access will allow us to more safely maintain, inspect and operate the system. It's an industry best practice and one of our many ongoing pipeline safety program upgrades and improvements taking place across our service area.

The Pipeline Pathways Program

  • A five-year system-wide gas safety program to enhance the safety of our natural gas pipelines—paid for by PG&E shareholders.
  • Allows PG&E to better maintain our high-pressure natural gas system and conduct important inspection, operation and maintenance of our pipelines.
  • Follows an established best practice supported by national pipeline safety organizations, such as the Pipelines and Informed Planning Alliance.

Enhancing the Safety of Our Pipelines

We are checking the area above our pipelines for items like sheds, patios, and trees. If structures are built or trees grow in above the pipeline, they can interfere with our ability to maintain, inspect and safely operate the system.

Trees can prevent us from getting to the pipeline in an emergency, and their roots can damage the protective coating around the pipe, which is the first layer of protection against corrosion.

In some circumstances, tree roots can wrap themselves around the pipe and in a situation where there are high winds, uproot the pipe which can rupture and cause dangerous gas leaks.

We are committed to working cooperatively with cities and property owners to discuss any necessary removals and conduct this work in a manner that balances the need to keep our communities both safe and beautiful. Most private properties do not have an underground natural gas transmission pipeline on their property. You can get more information about where our pipeline network runs by viewing a searchable pipeline map.

Marking for Safety

Marking for Safety Pipeline markers indicate the location of the underground pipe and are an important reminder to property owners, the community and our employees to use extra care around gas transmission pipelines. PG&E is in the process of replacing damaged or aging gas pipeline markers, and in some cases, placing new markers above the pipeline.
