Back in 1956, the California utility company Pacific Gas &
Electric laid a new gas pipeline, designated "132", to supply the
growing needs of San Francisco and cities to its south along the
peninsula. The 30-inch-diameter
pipeline's sections were welded together, and in one length near the town of
San Bruno, a lengthwise seam was welded in one section.
For many years, the pipeline carried natural gas northward to
San Francisco and surrounding communities, and as the population grew, PG&E
increased the pressure the pipeline carried so as to keep up with growing
demand. In 1956, weld-inspection
methods were fairly crude, and no one knew for sure how much pressure the
pipeline could stand.
PG&E is regulated by the California Public Utility
Commission (CPUC), so its profits and mode of operation are a creature of
government as much as a product of private industry. It is also a large publicly held corporation, ranking at 183
on the Fortune 500 list in 2014.
Under law, PG&E was obliged to take numerous safety measures to
ensure that its aging pipelines were not a public hazard. At one point, the firm got
authorization to collect a special fee to be spent on safety improvements and
upgrades. Somewhere along the
line, some of this safety-fee money was diverted instead to increases in
executive salaries. PG&E was
also supposed to keep up-to-date GIS (geographic information system) records of
the location and conditions of its pipelines, including seams such as the one
in the section lying under San Bruno.
In many cases, it failed to do so, as PG&E staffer Bill Manegold
found when he joined the company in 2005.
In 2008, instead of performing a laborious pipeline-inspection
procedure that would have involved shutting down the line, the firm
intentionally "spiked" the pressure on Line 132, in a mistaken belief
that if they failed to test it in this way, federal regulators would lower the
maximum allowable pressure the line could carry. According to state regulators, such spiking in turn required
an inspection of the line for damage, an inspection that PG&E never performed. In 2007 and again in 2010, PG&E
asked the CPUC for permission to spend $5 million on upgrading sections of Line
132, but the work was not carried out.
Given this background, it may come as no surprise to you that on
Sept. 9, 2010, residents of San Bruno heard a loud whooshing noise, followed by
a tremendous explosion and fire.
The seam-welded portion of the line had ruptured. In the ensuing holocaust in the middle
of the residential neighborhood that had grown up around the pipeline, 38 homes
were destroyed, dozens of people were injured, and eight persons died. One of those killed, Jacqueline Greig,
worked for the CPUC and had spent part of the summer investigating PG&E's
plans to replace outdated pipelines.
Hundreds of lawsuits were filed against PG&E, and on April 9
of this year, the firm agreed not to contest a $1.6 billion fine levied against
it by the CPUC. (That amount is
twice the company's total profits for 2014, incidentally.) Reportedly, PG&E has in the
meantime undertaken a massive effort to improve its safety and
pipeline-inspection practices, but the CPUC is considering whether to break up
the combined electric-gas utility into smaller pieces.
What went wrong here?
How could a large, supposedly competent organization of engineers and
managers allow an old pipeline to be put at such risk that it explodes and
destroys part of a neighborhood?
The National Transportation Safety Board, which investigated the accident,
sums it up by saying it was an "organizational accident" that was the
direct result of operational and managerial deficiencies.
The CPUC is not innocent in this case either. As the public entity charged with the
responsibility of ensuring that private firms such as PG&E operate safely,
it has come in for a lot of criticism as well. Levying a fine that is twice a company's annual profits is
something, but the real changes that have to happen are in the way PG&E
operates. And while fines are a
form of punishment that companies understand, probably the most that fines can
do is cause turnover in the executive suite, as disgruntled shareholders seek
new leaders who won't let such a fiasco happen again. There is no guarantee that the new managers will be any more
competent than the previous set, except possibly in the matter of avoiding
fines.
In all the words written about this disaster, I didn't see one
that I think holds the key to avoiding such disasters in the future: character. You don't hear much discussion about character in the face
of organizational failures, because we are trained to think of organizations
like physicists think of air molecules:
as collections of particle-like people who will behave according to laws
we can manipulate.
There is something to the idea that even good people in a flawed
organizational structure will end up doing bad things. But even the best organizational
structures cannot function well if the organization's people do not have
strength of character, and a healthy respect, if not fear, of what can go wrong
if their jobs are not done well.
The kind of fear that is needed was expressed well by a driver's
ed instructor I had in high school, back in the days when high schools had
driver's ed instructors. She
looked me straight in the eye and said, "You're about to sit behind the
wheel of a machine that can kill people.
Every time you drive, you will be personally responsible for the safety
of all the other drivers and pedestrians around you." It put the fear of God in me with
regard to how serious a matter driving was. While I have not always lived up to that instructor's ideal,
that fear I felt was a good thing in that it made me take driving seriously.
The ideal PG&E, and CPUC for that matter, would be composed
of individuals whose memory of the San Bruno tragedy is never very far from
their minds. Not everyone working
for those organizations is directly involved in safety matters. But safety ought to be built into the
consciousness of every employee to the extent that when those who are
technically qualified to speak about safety say something's wrong and needs to
be fixed, the entire organization should support all reasonable measures to
ensure that those safety needs are addressed. This includes things like replacing old lines when you get
the money to do it, and spending ratepayer's money designated for safety on
safety expenses, not extra pay for executives.
It's a shame that eight people had to die to reveal the
rottenness within the utility organizations responsible for the safety of
California residents. But
sometimes, that's what it takes to bring strength of character back where it
belongs.
