Deactivated gas line inspection program (DGLI)

Project overview

PSE’s deactivated gas line inspection program (DGLI) inspected retired natural gas services across our system to confirm they were properly deactivated. This included evaluating active, above ground services to help ensure they were not susceptible to damage such as tampering or vandalism.

PSE crews began inspecting our deactivated pipelines in summer 2017. Their work concluded in December 2020, after completing over 40,700 site inspections. Through the DGLI program, we confirmed that all of PSE’s retired natural gas services were properly deactivated.

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. When improving and operating our system, we follow or exceed strict federal and state safety requirements related to pipeline safety. Check Gas Safety Tips for more information on natural gas safety.
