SACRAMENTO, Calif., Feb. 20, 2013 /PRNewswire/ --Pacific Gas and Electric
Company (PG&E) today hosted a Gas Safety Fleet Expo at its service center in
Sacramento for employees and the community to experience three of the new or
redesigned vehicles in use across its service area. Each of the vehicles
allows PG&E crews to better assess where improvements can be made to its gas
pipeline system in order to ensure safe and reliable gas operations. 

"We're giving our employees the tools they need to make our natural gas system
safer. That is why we're using state-of-the-art Picarro leak detection
technology, and getting our gas crews involved to redesign a truck that helps
them do their jobs more effectively and efficiently," said Kevin Knapp, vice
president, gas distribution maintenance and construction, PG&E. "Our gas crews
are using some of the most well-equipped vehicles to help ensure safe gas
operations across our service area. Our new mobile command vehicle increases
our response capability and provides on-site field support like never before."

Mounted on PG&E vehicles, the Picarro Surveyor™ devices are approximately
1,000 times more sensitive than traditional leak detection equipment. This
increased accuracy helps PG&E field crews quickly and efficiently identify
where potential leaks may exist. The easy-to-use analyzer and cloud-based
analytics send an alert to users and repair teams immediately upon detecting a
leak. In October 2012, PG&E deployed an additional six vehicles with the
Picarro Surveyor devices, bringing its total fleet to eight.

The first employee-designed Gas Crew Truck was delivered in October 2012 after
hundreds of PG&E employees provided input used to develop the new vehicles.
The redesigned truck features a host of improvements including: a more
advanced braking system, a roll-up compartment door for safer access on busy
streets, a loading device for heavy equipment and greater fuel economy.
Tracy-based American Truck & Trailer Body Company, Inc. will supply PG&E with
57 new Gas Crew Trucks, with plans to produce an additional 55 to 60 over the
next three years.

Additionally, PG&E's mobile command vehicle has been designed to handle
large-scale events that require crews to work in teams for extended periods of
time. The vehicles are built on a 40-foot bus chassis and can house a dozen
people for days or weeks, if needed, to address any emergency needs. These
units are some of the most technologically advanced vehicles in production and
help PG&E gas crews provide the right response capability direct to the scene.

"Picarro Surveyor is designed to help gas crews quickly identify potential
leaks with great accuracy and enhance the safety of PG&E's natural gas
system," said Mike Woelk, CEO of Picarro. "Our technology is the
first-of-its-kind used in the utility industry, and we applaud PG&E's
commitment to having the safest natural gas distribution in North America and
being the first to deploy Picarro's technology."

Picarro Surveyor, the redesigned Gas Crew Truck and the mobile command vehicle
are just three of many vehicles PG&E is currently using to enhance the safety
and reliability of its natural gas pipeline system. By deploying these and
other technologies across its service area, PG&E is driving innovation – all
in the name of safety.
