* Board calls for Calif. to adopt "safety case" system
* Recommendations in wake of Chevron 2012 refinery blaze
* Calif. officials weigh possible new rules for refineries

HOUSTON, Dec 16 The U.S. Chemical Safety Board
on Monday called on California officials to adopt new rules for
crude oil refineries that would force owners to prove they can
operate their plants at the lowest risk practicable, the federal
investigative agency said.
An interagency working group representing California state
agencies recommended similar action to California Gov. Jerry
Brown in July.
The board said the recommended move to a "safety case"
system like that in the United Kingdom and Australia grew out of
the board's probe of the Aug. 6, 2012 fire at Chevron Corp's
San Francisco Bay-area refinery in Richmond, California.
A Chevron spokeswoman, in a statement on Monday afternoon,
did not address the CSB's recommendations for changes in the
system for regulating California refineries.
"Chevron U.S.A. Inc. will continue to work with the U.S.
Chemical Safety Board, the City of Richmond, Contra Costa County
and other regulatory agencies and industry groups to implement
appropriate measures that enhance safety at our Richmond
facility," said Chevron's Melissa Ritchie.
The Aug. 6, 2012 fire sent a gigantic plume of thick black
smoke and particles into the sky over the Bay area, leading
15,000 people to seek medical treatment in the days afterward.
"Refinery safety rules need to focus on driving down risk to
the lowest practicable level, rather than completing required
paperwork," said CSB Chairman Rafael Moure-Eraso on Monday.
"Companies, workers, and communities will all benefit from a
rigorous system like the safety case. I believe California could
serve as a model for the nation by adopting this system."
The board has no regulatory or enforcement authority, but
only investigates incidents that fall under the jurisdiction of
the U.S. Clean Air Act. The CSB makes recommendations to
government and industry as it deems necessary.
Worker safety regulation in California is performed by a
state agency, the California Division of Occupational Safety and
Health (Cal/OSHA), in contrast with most states where safety
rules are enforced by the U.S. Occupational Safety and Health
States can carry out worker safety regulation if their rules
are equal to or more strict than that of the federal OSHA.
California's rules are seen as more stringent than the federal
The board warned switching from the current activity-based
system like that enforced by Cal/OSHA would require a
"well-funded," "technically competent" regulator with a
compensation system that can attract and retain well-trained and
The CSB did not say how much more the new system would cost.
Critics have previously said the recommended safety case
system would essentially be a form of self regulation if there
are not government inspectors who audit refineries and carry
The CSB also said the safety case could also be dynamic
reacting to changes in industry standards and discoveries about
refinery risk more quickly than the current system.
In a report issued in April, the CSB said that the Aug. 6
2012 fire at the 245,000 barrel-per-day (bpd) refinery sprang
from a leak of hydrocarbon coming from a pipe on the refinery's
sole crude distillation unit.
Board investigators found Chevron bypassed several
opportunities to replace the pipe, which had become dangerously
thin prior to the fire due to corrosion caused by the sulfur
found in crude oil.
The crude distillation unit, which does the initial refining
of crude oil coming into the refinery and provides feedstock for
all other production units, was shut for nine months after the
blaze, cutting gasoline production by at least 50 percent.
Chevron has since replaced the damaged pipes on the crude
unit with corrosion resistant piping. The company continues to
carry out investigations on pipes at the refinery, replacing
piping as needed, Chevron has said.
In January, Cal/OSHA issued 25 citations for worker safety
violations to Chevron related to the Aug. 6, 2012 blaze, with
fines totaling $963,200.
"We provided approximately $10 million to affected community
members and local government agencies in Richmond and West
Contra Costa County for medical and response-related costs,"
The CSB recommendations issued on Monday will not be final
until the board formally approves them at a meeting in January.
