Customer growth throughout the greater Tacoma and west Pierce County areas is straining the natural gas system. In order to maintain the current reliability of the natural gas system in the area and ensure we can continue to provide our customers with dependable service in the future, PSE plans to strengthen and upgrade the natural gas system in the area.

These system improvements will ensure that PSE can continue to reliably provide natural gas to current and future customers, especially on the coldest days of the year when gas is in highest demand. During such periods, the LNG facility will convert LNG back to natural gas, inject it with a strong odorant called mercaptan, which gives the gas its familiar rotten-egg smell, and deploy it into the gas distribution system.

PSE installed approximately four miles of 16-inch natural gas distribution pipeline in Fife, Tacoma and the Port of Tacoma in order to supply natural gas to and deliver it from the Tacoma LNG facility.


At PSE, we know our customers, employees and the communities we serve expect to live and work around a safe and reliable natural gas system. Safety is our top priority when it comes to designing, constructing, operating and maintaining the natural gas system serving more than 800,000 PSE customers. When improving and operating our system, we follow or exceed strict federal and state safety requirements related to pipeline safety. Click here for more information on natural gas safety.

How does natural gas get to my home or business?

Natural gas is a fossil fuel composed almost entirely of methane. Interstate pipelines transport natural gas to regional natural gas systems, where it is metered and delivered through a network of local mains, service lines and, ultimately, to customer homes and businesses.

Committed to keeping you informed

PSE will continue to provide updates to the community. We'll notify residents and business near the project area when construction will occur. We aim to complete this work with as little disruption as possible.
