Project overview

At PG&E, our most important responsibility is the safety of our customers and the communities we serve. As part of that responsibility, we will be performing a strength test on our underground natural gas transmission pipeline in the East Bay. This routine safety testing work is mandated by the California Public Utilities Commission (CPUC) and is a type of integrity management testing conducted every seven years. The strength test will confirm the gas pipeline’s integrity and operating pressure.

From February 2019 through November 2019, we will test seven segments of our natural gas system from San Leandro to San Pablo. During this test, we empty the pipeline of gas, fill it with water and pressurize it to a level higher than normal operating pressure. We then repair or replace any section of the pipeline that does not meet safety standards. Mobilization and testing will take place intermittently over the course of three to four months in each area, with full restoration occurring soon after the completion of work.

You may see PG&E and contractor trucks and other heavy equipment as part of our work. There may also be a controlled and safe release of a small amount of natural gas. You may hear a loud steady noise and notice the smell of gas.
