SAN RAMON, Calif. (AP) — Pacific Gas & Electric Co. has opened a new, $38 million natural gas monitoring center in the wake of the deadly 2010 gas line explosion in San Bruno.

PG&E spokeswoman Brittany Chord says the new center allows the utility to better monitor its gas transmission system and coordinate and respond in case of an emergency. In addition to 6,700 miles of gas transmission pipeline, the new center also monitors the utility's 42,000 miles of gas distribution pipeline. Distribution lines are the narrow-diameter pipes that serve individual homes and businesses.

The new center will also put the employees who dispatch PG&E workers in the field in the same room as the system monitors.

The center went online late last week.

Critics tell the Contra Costa Times PG&E must still do more toguarantee the system's safety.
