SAN FRANCISCO, Dec. 18, 2012

SAN FRANCISCO, Dec. 18, 2012 /PRNewswire/ --Building on its commitment to
natural gas pipeline safety, Pacific Gas and Electric Company (PG&E) announced
that it validated the safe operating pressure of an additional 194 miles of
natural gas transmission pipeline in 2012, through hydrostatic pressure
testing and rigorous records validation.

These activities were completed in areas throughout Northern and Central
California as part of PG&E's Pipeline Safety Enhancement Program (PSEP) and
through regularly scheduled projects to verify the integrity of natural gas
transmission lines—the large-diameter pipes that carry gas across long
distances. Since PSEP projects launched in 2011, PG&E has successfully tested
a total of 409 miles of gas transmission pipeline.

PG&E also started construction on a state-of-the-art gas control center at its
new Gas Operations headquarters at Bishop Ranch in San Ramon, Calif. The
center will serve as a central location from which PG&E will monitor the safe
and reliable operation of its 6,700 miles of transmission pipeline and 42,000
miles of smaller-diameter distribution mains. Completion of the gas control
center is expected in Q2 2013.

"There is nothing more important than working to make our natural gas system
safer in the communities we serve. We've made tremendous progress, but the
work we've done is just the beginning," said Nick Stavropoulos, executive vice
president of Gas Operations for PG&E. "Our goal is to operate the safest and
most reliable natural gas system in the country."

Hydrostatic pressure testing is one of several important measures PG&E is
taking to enhance the safety and strength of its natural gas system. Through
the end of 2014, phase one of the PSEP program, the utility plans to pressure
test or validate 783 miles of gas transmission pipeline, replace 185 miles of
pipeline, automate more than 220 valves, and upgrade nearly 200 miles of
pipeline to accommodate advanced in-line inspection tools known as "smart

"PSEP is a multi-year program that will enhance the safety and reliability of
our natural gas transmission pipelines in communities throughout our service
area. It will help us to assess our pipeline system and improve the delivery
of safe, reliable and affordable natural gas to our customers," said Jesus
Soto Jr., senior vice president of Gas Transmission Operations for PG&E.

This year, in addition to validating the safe operating pressure of 194 miles
of pipeline, PG&E has made significant progress in improving transmission
pipeline safety and reliability including: 

  oInstalling more than 34 miles of new transmission pipeline in urban areas.
  oInstalling 37 automated valves in urban or active seismic fault crossing
    areas to allow for remote or automated shut-off in the event of a rupture.
    Fifty valves have been completed since the program commenced in 2011. 
  oRetrofitting 78 miles of pipeline to accommodate state-of-the-art in-line
    inspection tools known as "smart pigs." 

In 2013, the utility plans to further increase its pipeline safety actions,
with plans to strength test more than 200 miles of pipeline, replace more than
60 miles of pipeline and automate 75 valves – all in addition to work
completed to date.
