An analysis finds more than 75 towns and cities with populations over 1,000 where, like Paradise, at least 90 percent of residents live within Cal Fire’s “very high fire hazard severity zones.”
The Facebook post could be a bit misleading if you assume Benicia is among the 10 California Communities identified in the KQED story. But if you dig in a bit, you find an interactive map. Drilling down into this map, you find Benicia’s Valero Refinery surrounded by a “High Fire Hazard Zone” (dark orange).
Expand the map a bit and scroll around the Bay Area and you find that refineries in Martinez and Rodeo are located near VERY High Fire Hazard zones (red).
Questions should be asked at the Council meeting to assure the public:
Are adequate preparations in place for cutting back combustible materials in and near Benicia’s Industrial Park?
Will adequate watch be undertaken by the two fire departments (Valero and City of Benicia) during California’s expanding fire season?
Are plans to fight wildfire in the eventuality of an outbreak detailed, robust, and well-rehearsed?
Of course, the lives of refinery workers and nearby Industrial Park workers, and indeed the lives and well-being of all Benicia residents are put at risk as climate change increases the odds for wildfires in our beautiful part of the world. Vigilance is required!
State workplace regulators, the region’s local air quality district and Solano County health officials are trying to find out why a problem at Valero’s Benicia refinery suddenly worsened over the weekend, leading to a release of petroleum coke dust that prompted fire officials to urge those with respiratory problems to stay indoors.
The incident led to a partial shutdown at the facility and represents the worst malfunction at the plant since a power outage caused a major pollution incident in 2017.
The releases of elevated levels of particulate matter led several residents to complain of breathing problems and prompted Benicia’s mayor to call on Valero to pay the city back for its work dealing with the emergency. The partial refinery shutdown is also expected to lead to a spike in higher gasoline prices throughout the state.
Mayor Elizabeth Patterson said she’s gotten a flood of phone calls and emails from residents wanting to know why it took so long for Valero to suspend refinery operations.
“There’s a lack of understanding about how coke particulates could be continuously emitted throughout a couple of weeks,” Patterson said. “There’s not a lot of information that’s readily available to the public.”
California’s Division of Occupational Safety and Health began a probe into Valero on Monday, the day after the company began the gradual shutdown of a significant portion of the refinery, according to agency spokesman Frank Polizzi.
Cal/OSHA becomes the latest government agency to look into the breakdown of a key piece of equipment inside the refinery that went down two weeks ago. The Bay Area Air Quality Management District and Solano County officials have launched probes as well.
Refinery Problems Started Two Weeks Ago
On March 11, the facility’s flue gas scrubber began malfunctioning. That meant the facility’s smokestacks began belching a sooty plume of petroleum coke dust — minute carbon particles that are a byproduct of the oil refining process.
The initial problem prompted the Bay Area Air Quality Management District to issue eight notices of violation against Valero.
The air district and Solano County health officials said during the following days that the flue gas scrubber had been fixed and the coke dust releases were intermittent and gradually coming to an end.
But the black smoke returned on Saturday. On Sunday, fire officials detected high levels of fine particulate matter, known as PM10, around the refinery and issued a health advisory urging people with respiratory issues to stay indoors.
“What we were seeing was dark gray, almost black smoke coming from the flue gas scrubber unit,” Benicia Fire Chief Josh Chadwick said Monday.
PM10 is particulate matter 10 micrometers or less in diameter — larger than PM2.5 many became familiar with during last November’s Camp Fire, when smoke from the huge Butte County blaze prompted health advisories throughout much of Northern California.
Like PM2.5, the larger particulate matter is regulated by the Environmental Protection Agency.
EPA spokeswoman Soledad Calvino said the agency would not comment on ongoing or potential investigations.
The agency has said that once inhaled, petroleum coke dust can affect the heart and lungs and cause serious health effects.
“The additional concern is that this is more toxic than the standard stuff you’d find in the atmosphere,” said Anthony Wexler, director of the Air Quality Research Center at UC Davis. “It’s probably similar in toxicity to diesel exhaust, which is a known carcinogen because it’s sooty in nature.”
On Sunday morning the wind in the Benicia area was blowing east to west at about 6 to 12 mph, according to meteorologist Jan Null.
That meant the coke dust was being blown toward residential neighborhoods, said Chadwick.
“That was one of the big concerns I had,” Chadwick said. “We had a wind shift … that really turned it back toward the city.”
Several Residents Complain of Breathing Problems
Chadwick said the Benicia Fire Department received two 911 calls for respiratory complaints. One of the calls was for one person who was transported to John Muir Medical Center in Concord. The other was for two people who told paramedics who showed up they didn’t need to be hospitalized.
The wind on Sunday also sent the coke dust toward parts of Contra Costa County, according to air district spokesman Ralph Borrmann. The agency received several complaints from people in Benicia and a few in Rodeo, Borrmann said.
Fire crews have been conducting air readings since Sunday morning and the levels of particulate are back to normal, Chadwick said.
Air district officials are expected to release the results of their testing later this week.
It’s unclear why the flue gas scrubber began malfunctioning again.
Terry Schmidtbauer, Solano County’s assistant director of resource management, said his department’s investigation is focused on the scrubber unit, other refinery components that interact with the device and if refinery workers made a mistake in operating the unit.
It’s also uncertain how long it will take to shut down the affected parts of the refinery and how long that closure will last.
“I am not sure how long Valero intends to have the affected portion shut down,” Schmidtbauer said in an email.
Lillian Riojas, a Valero spokeswoman, did not answer questions about how long the shutdown should last.
On Sunday the company issued a statement about the refinery problem.
“There may be a visible plume and flaring as part of the shutdown,” Valero’s statement said.
Mayor Renews Call for More Refinery Regulations
Mayor Patterson has been calling for more regulation of Valero’s facility ever since the May 5, 2017, refinery incident — a push that so far has failed to result in action.
The City Council rejected her proposal to develop an industrial safety ordinance, similar to one in Contra Costa County, that provides more information to town officials about refinery problems.
The latest incident has prompted her to renew her call for action.
“We definitely need an industrial safety ordinance with the fees to cover the costs that it’s costing the city,” Patterson said. “When we are responding to these things, that means we’re not doing something else.”
Patterson said she planned to bring up the issue of compensation at a City Council session this Saturday.
A Bay Area environmental group critical of the oil industry and the agencies regulating it said the episode should raise concern about operations at other facilities.
“This is the latest sign that Bay Area refineries and our air quality officials can’t safely cope with current workloads, let alone the increased volume of oil processing planned by the industry,” said Hollin Kretzmann, an Oakland-based lawyer for the Center for Biological Diversity.

Chevron’s Richmond Refinery Flaring Incidents at Highest Level in More Than a Decade
By Ted Goldberg, Mar 18, 2019
The number of flaring incidents in 2018 at Chevron’s Richmond refinery was at its highest level in 12 years, according to data the Bay Area Air Quality Management District released Monday at a board of directors committee meeting.
The refinery experienced nine flaring events last year, more than any other refinery in the Bay Area. That’s the highest number of such incidents since 2006, when the Chevron refinery experienced 21 flaring events.
The Tesoro refinery in Pacheco experienced five flaring incidents last year, Valero’s Benicia refinery conducted four, Shell in Martinez had three and Phillips 66 in Rodeo had two, according to the air district.
The jump, which started in the last eight months, is connected to the start up of a new hydrogen plant that recently began operating at the facility, according to John Gioia, who represents the area of the refinery on the Contra Costa County Board of Supervisors and sits on the air district’s board of directors.
“All the sudden we saw this spike,” Gioia said in an interview. “There are some issues related to the new hydrogen plant and how it is integrated with the existing refinery.”
Gioia said it will probably take several months for Chevron to make fixes at the plant to reduce future flaring operations.
“For those of us who live in Richmond, we may continue to see some additional flaring while these issues are resolved,” he said.
Air regulators and oil industry officials emphasize that flares are used as safety devices to reduce pressure inside refineries by burning off gases during facility malfunctions as well as start up and shutdown operations.
Braden Reddall, a company spokesman, said late Monday that the refinery was flaring “due to startup activities at a processing unit.”
“The flaring does not pose any environmental or health risk to the community,” Reddall said in an email.
“We want to assure our neighbors that flares are highly regulated safety devices, designed to relieve pressure during the refining processes and help keep our equipment and plants operating safety,” he said, adding that the refinery continues to supply its customers.
But Reddall did not answer questions about the connection between the hydrogen plant and the refinery’s recent uptick in flaring incidents as well as what kind of fixes the company is putting in place.
Gioia said the refinery began using the hydrogen unit last fall.
In the first three months of 2019, there have been five malfunctions at Chevron, the most recent one on Sunday afternoon, according to Randy Sawyer, Contra Costa County’s chief environmental health and hazardous materials officer.
That incident sent black smoke into the air and lasted two-and-a-half hours, Sawyer said.
It came 11 days after the refinery suffered an outage that caused several processing units at the facility to shut down, prompting the facility to send gas through its flares.
The refinery also suffered outages on Feb. 2 and Jan. 17 and conducted a separate flaring operation on Feb. 24.
The air district is investigating most of those incidents, according to agency spokeswoman Kristine Roselius.
“We don’t think this is an acceptable situation,” said Jack Broadbent, chief executive officer of the air district, during Monday’s meeting before the district’s Stationary Source Committee.
Gioia said a significant portion of the gas coming from the refinery’s flares during the recent incidents has been pure hydrogen, which does not present the same health risk as other gases like sulfur dioxide and benzene, which tend to get released during other flaring operations.
Tar Sands Free SF Bay – Town Hall meeting Thurs Mar 7 2019, Rodeo Hills Elementary
Feb 27, 2019
This coming Thursday, refinery corridor residents and allies are presenting a community forum on Phillips 66’s very dangerous plans to expand tar sands refining at its Rodeo facility.
Increased use of tar sands in the P66 crude slate means vastly increased tanker traffic in the Bay, an increased risk of spills, and increased assaults on community health and our worsening climate. This town hall is an opportunity to learn about the two linked P66 proposals—the first Environmental Impact Report drops soon—and what we can do to stop them.
Please come out to listen, learn, and offer support to impacted community residents.
