BENICIA – The Bay Area Air Quality Management District announced Thursday that it had discovered continued violations at the Valero Benicia refinery during its investigation into years of toxic releases.
Specifically, the air district said that Valero had failed to install required pollution control equipment on eight pressure relief devices, safety devices that prevent extreme over pressurization that could cause a catastrophic equipment failure. The violations led to 165 tons of illegal emissions, the air district said. [Emph. added by BenIndy contributor.]
The air district said it is seeking an abatement order from its independent hearing board that would require Valero to immediately correct the violations.
“The extensive violations discovered at Valero’s Benicia refinery are of great concern,” air district chief counsel Alexander Crockett said in a statement. “Our priority is to protect the health and well-being of our communities, and we will vigorously pursue enforcement measures to achieve cleaner and safer air for all residents of the Bay Area.”
A Valero spokesperson did not immediately respond to a request for comment.
Benicia Mayor Steve Young said in a statement that Valero’s alleged continued pattern of emissions violations is “particularly concerning” and “should bother all Benicia residents.”
“The City is also waiting, with increasing impatience, to see how the separate, bigger, case of 16 years of unreported hydrogen emissions will be ultimately resolved,” Young said. “The citizens of Benicia deserve much more transparency from the refinery about these operational deficiencies than we have been receiving.”
The air district discovered the violations during its investigation into the release of toxic emissions from a hydrogen vent at the refinery that went on for nearly 20 years. The air district separately obtained an abatement order for those violations last year, though by the time it revealed the excess emissions publicly, it had already worked with Valero to correct them for some time.
Those excess emissions were first detected by Valero in 2003 when it started measuring output from the hydrogen vent, but the air district believes it likely had been going on even earlier and has no measurements from that time.
Since 2003, the air district estimates that the vent was releasing about 4,000 pounds of hydrocarbons per day, far more than state regulations allow. Overall, the district found that Valero released more than 10,000 tons of excess hydrocarbons over 16 years, including 138 tons of toxic air contaminants ethylbenzene, tolyrene, zolerine and the especially carcinogenic benzene.

The EG.5 “Eris” variant is now the dominant COVID-19 strain in the U.S. Here’s what to know about transmission and symptoms.
A new COVID-19 variant called EG.5 is sweeping across the United States as cases and hospitalizations rise. The fast-spreading new COVID subvariant, also referred to as Eris, is now the dominant strain circulating in the U.S., health officials say.
As of last week, EG.5 accounted for the largest proportion of COVID-19 infections in the country compared to any other variant, according to the latest data from the U.S. Centers for Disease Control and Prevention,
Eris is also on the rise in several other countries around the globe. On Wednesday, Aug. 9, the World Health Organization decided to classify EG.5 as a “variant of interest.”
The new subvariant, which experts nicknamed “Eris” on social media, started circulating in the U.S. earlier this spring. Last month, EG.5 quickly overtook the prevailing omicron XBB subvariants, which had been driving the largest share of cases in the country.
During a two-week period ending on Aug. 5, Eris accounted for an estimated 17.3% of new confirmed COVID-19 cases in the U.S., up from 12% two weeks prior, according to the latest CDC data.
Many are wondering if the EG.5 subvariant is more transmissible or severe, and whether it’s causing different symptoms.
What is EG.5 , aka Eris?
EG.5 is a descendant of the omicron XBB sublineage of the virus (specifically, XBB.1.9.2), but it has an extra mutation in its spike protein, according to a WHO risk evaluation report.
“When we look at its sequence, EG.5 is really similar to the other XBB variants that are circulating right now, with a couple of small changes,” Dr. Andrew Pekosz, a virologist at Johns Hopkins University, tells TODAY.com.
The WHO added EG. 5 to its list of variants under monitoring on July 19, 2023, but the variant was first detected in February 2023. “Scientists have known about this variant, and it’s been present in other countries, as well,” says Pekosz.
So far, EG.5 has been reported in 51 countries and there has been a steady increase in prevalence globally — the majority of sequences are from China, followed by the U.S., South Korea, Japan and Canada, per WHO.
XBB.1.16, also called the “Arcturus” variant, remains the most prevalent strain of COVID-19 worldwide.
WHO considers the public health risk posed by EG.5 to be “low” and similar to that of XBB.1.16 and other variants of interest.
Is EG. 5 more transmissible?
The EG.5 variant is very similar to other omicron variants, which means it’s highly transmissible, Dr. Albert Ko, an infectious disease physician and professor at Yale School of Public Health, tells TODAY.com.
However, EG.5 is likely more transmissible than other XBB variants, Dr. Sharon Nachman, chief of the division of pediatric infectious diseases at Stony Brook Children’s Hospital, tells TODAY.com.
“If it was equally transmissible, then we wouldn’t see it gaining strength number-wise compared to some of the other variants,” says Nachman, adding that EG.5 quickly pushed out other XBB variants in the U.S., which were dominant over the summer.
Why exactly EG.5 is more transmissible is not yet known, Ko says.
“Whether it’s escaping population immunity or it has some intrinsic factor that makes it better able to transmit from one person to another … it’s hard to separate,” he adds.
According to WHO, EG.5 has increased immune escape properties compared to other variants. “EG.5 may cause a rise in case incidence and become dominant in some countries or even globally,” WHO said in a report.
However, Pekosz notes that the EG.5 variant may not be the sole reason for the U.S. summer uptick. “When you have a new variants, and cases creeping up, there’s always concern about whether that variant could be driving the increase,” says Pekosz.
“Right now, it doesn’t look like that variant alone is driving the case increases (in the U.S.) … there’s still a lot of other variants co-circulating,” he adds.
According to CDC estimates, EG.5 accounted for about 17% of COVID-19 cases in the U.S. during the two-week period ending on Aug. 3. — after EG.5, the next most common variants were XBB.1.16, XBB.2.3, and XBB.1.5, which accounted for 15%, 11% and 10% of cases, respectively.
“We’re keeping an eye on (EG.5) because of the uptick in cases, but it doesn’t look like there’s anything particularly concerning about this variant,” says Pekosz.
More data is needed to understand how EG.5’s transmissibility compares to other strains. However, decreased levels of testing and genomic sequencing are making it harder to accurately track new COVID-19 cases and which variants are driving them, Pekosz notes.
“Right now, there’s an awful lot of guesswork,” he says.
Is EG.5 more severe?
The data available do not indicate that EG.5 causes a more severe infection compared to other variants, the experts note.
In its risk assessment of EG.5, WHO said, “There have been no reported changes in disease severity to date.”
Although the U.S. recently saw the first increase in COVID-19 hospitalizations of the year, there isn’t evidence that EG.5 is causing this uptick or that it’s more likely to cause hospitalizations in general, Nachman notes.
“The people that are getting hospitalized often have lots of co-morbidities, and they’re at-risk no matter what COVID strain they get,” says Nachman.
However, it’s possible that hospitalizations could increase even more because of more people getting infected with EG.5, says Ko. “There’s no clear evidence of that at this point, but we have to keep on evaluating,” Ko adds
Population immunity from vaccination and prior infection should protect people from severe illness as EG.5 continues to circulate.
What are the symptoms?
There isn’t enough clinical data about the most common symptoms of EG.5 yet, NBC News previously reported.
“There’s no change in EG.5 symptoms right now,” says Pekosz. So far, the symptoms of EG.5 look very similar to the standard omicron symptoms, says Ko. These include:
Cough
Sore throat
Runny nose
Sneezing
Fatigue
Headache
Muscle aches
Altered sense of smell
“It may progress to some more significant feelings of difficulty in breathing as the infection spreads into your lungs,” says Pekosz.
Certain groups are at higher risk of developing severe illness or complications, including people over 65 and those who are immunocompromised or have underlying medical conditions.
Can COVID-19 tests detect EG.5?
All COVID-19 tests — including PCR tests performed by a medical provider and rapid at-home antigen tests sold over-the-counter — should be detecting EG.5, says Pekosz.
The experts emphasize the importance of getting tested as COVID-19 cases increase, and especially during the fall when viruses that cause similar symptoms (such as flu and RSV) are circulating.
“If you’re in one of the high-risk groups for getting severe COVID, you really shouldn’t hesitate to get a test,” says Pekosz, adding that early detection and treatment is key. COVID-19 antivirals such as Paxlovid are effective against EG.5 and other variants, but they work best when taken early, he adds.
Whether your insurance covers COVID-19 testing may have changed since the end of the U.S. federal public health emergency in May, TODAY.com previously reported, so check with your insurer if you have questions about testing costs.
It’s also important to check the expiration date of at-home tests. The shelf life of rapid tests ranges from four to 24 months, according to the U.S. Food and Drug Administration, but the expiration dates of some tests have been extended.
Will I need a COVID-19 booster this fall?
The experts encourage everyone to stay up to date on COVID-19 vaccines, which may include a new booster dose in the coming months. In June 2023, the FDA advised vaccine manufacturers to update their boosters to target omicron XBB.1.5, which was the dominant strain at the time.
These shots haven’t been approved yet, but the FDA could authorize Pfizer’s booster shot by the end of August, NBC News reported.
Although the new boosters will not include the EG.5 strain, they may still provide protection, the experts note. “If I vaccinate you with the vaccine that contains XBB, you will make antibodies that are specific to XBB and pretty close to EG.5,” says Nachman.
“Right now, EG.5 looks like it’s very closely matched to the vaccine that’s going to be available this fall,” says Pekosz.
However, the CDC has not yet released any firm guidance or recommendations around booster doses for the fall.
“The message is to pay attention to the COVID vaccine program that’s going to come out in the fall. … It’s a vaccine that many people (especially high-risk individuals) should consider taking,” says Pekosz.
How to protect yourself from EG.5:
In addition to staying up to date on COVID-19 vaccinations, the experts emphasize taking precautions to protect yourself and curb transmission of COVID-19, including:
Requested abatement order would require the refinery to install pollution control equipment

FOR IMMEDIATE RELEASE: August 10, 2023 CONTACT: communications@baaqmd.gov
SAN FRANCISCO – The Bay Area Air Quality Management District announced today that it is seeking an abatement order from the agency’s independent Hearing Board to require Valero Refining Co. to cease ongoing violations of Air District regulations at its Benicia refinery.
The Air District is seeking an abatement order to require Valero to install pollution control equipment on eight pressure relief devices, or PRDs, installed on the refinery’s hydrogen compressor unit. PRDs are safety devices used to prevent extreme overpressures that could cause catastrophic equipment failure – not unlike the pressure relief valve on a home pressure cooker, but on an industrial scale.
Air District regulations require pollution control equipment to be installed on PRDs that experience two or more releases within five years. Valero’s PRDs have been subject to these requirements for years, and in some cases for over a decade, but Valero has failed to install the required pollution control equipment.
“The extensive violations discovered at Valero’s Benicia refinery are of great concern and the Air District is seeking an abatement order to ensure that Valero takes action to prevent harmful emissions from impacting the communities surrounding the refinery,” said Alexander Crockett, the Air District’s chief counsel. “Our priority is to protect the health and well-being of our communities, and we will vigorously pursue enforcement measures to achieve cleaner and safer air for all residents of the Bay Area.”
PRDs release emissions during upset conditions and not on a day-to-day basis. However, when PRDs releases do occur, the emissions go directly to the atmosphere unless they are captured and/or abated. The Air District is seeking this abatement order to require abatement equipment to prevent emissions from going into the atmosphere if and when any PRDs do experience releases.
Air District staff discovered these PRD violations in connection with an investigation into a series of widespread violations involving Valero’s hydrogen system, including extensive emissions from a hydrogen vent for which the Hearing Board issued an abatement order in 2022. Valero is required to report releases from its hydrogen system PRDs to the Air District, but it failed to do so for over ten years. As a result, these ongoing violations did not come to light until the Air District conducted further investigations after it found the hydrogen vent violations.
The Air District’s Hearing Board is an independent tribunal created by state law with the power to order violators to cease operating until they come into compliance with Air District regulations. Hearing Board proceedings are open to the public, and the public is encouraged to participate and comment when the Hearing Board holds a hearing to consider issuing the requested abatement order. Once the hearing is scheduled, a link will be posted on the Air District’s website at www.baaqmd.gov. The public can also sign up for Hearing Board updates at https://www.baaqmd.gov/contact-us/sign-up-for-information.
The Hearing Board is not empowered to impose monetary penalties for violations of Air District regulations. The Air District will take separate enforcement action to assess penalties for these violations to the maximum extent provided for by law. The purpose of this abatement order request is to seek an order requiring Valero to cease its ongoing violations with respect to these PRDs and immediately come into compliance.

Air pollution is helping to drive a rise in antibiotic resistance that poses a significant threat to human health worldwide, a global study suggests.
The analysis, using data from more than 100 countries spanning nearly two decades, indicates that increased air pollution is linked with rising antibiotic resistance across every country and continent.
It also suggests the link between the two has strengthened over time, with increases in air pollution levels coinciding with larger rises in antibiotic resistance.
“Our analysis presents strong evidence that increasing levels of air pollution are associated with increased risk of antibiotic resistance,” researchers from China and the UK wrote. “This analysis is the first to show how air pollution affects antibiotic resistance globally.” Their findings are published in the Lancet Planetary Health journal.
Antibiotic resistance is one of the fastest-growing threats to global health. It can affect people of any age in any country and is already killing 1.3 million people a year, according to estimates.
The main drivers are still the misuse and overuse of antibiotics, which are used to treat infections. But the study suggests the problem is being worsened by rising levels of air pollution.
The study did not look at the science of why the two might be linked. Evidence suggests that particulate matter PM2.5 can contain antibiotic-resistant bacteria and resistance genes, which may be transferred between environments and inhaled directly by humans, the authors said.
Air pollution is already the single largest environmental risk to public health. Long-term exposure to air pollution is associated with chronic conditions such as heart disease, asthma and lung cancer, reducing life expectancy.
Short-term exposure to high pollution levels can cause coughing, wheezing and asthma attacks, and is leading to increased hospital and GP attendances worldwide.
Curbing air pollution could help reduce antibiotic resistance, according to the study, the first in-depth global analysis of possible links between the two. It also said that controlling air pollution could greatly reduce deaths and economic costs stemming from antibiotic-resistant infections.
The lead author, Prof Hong Chen of Zhejiang University in China, said: “Antibiotic resistance and air pollution are each in their own right among the greatest threats to global health.
“Until now, we didn’t have a clear picture of the possible links between the two, but this work suggests the benefits of controlling air pollution could be twofold: not only will it reduce the harmful effects of poor air quality, it could also play a major role in combatting the rise and spread of antibiotic-resistant bacteria.”
Although air is recognised as being a direct pathway for disseminating antibiotic resistance, there is limited data on the different pathways that antibiotic resistant genes are carried via air pollution.
Potential pathways include hospitals, farms and sewage-treatment facilities that emit and spread antibiotic-resistant particles through the air and then across wide distances.
Until now, there was limited data on how much influence PM2.5 air pollution – which is made up of particles 30 times smaller than the width of a human hair – has on antibiotic resistance globally.
Sources of PM2.5 include road traffic, industrial processes and domestic coal and wood burning. Data indicates 7.3 billion people globally are directly exposed to unsafe average annual PM2.5 levels.
The authors created an extensive dataset to explore whether PM2.5 was a key factor driving global antibiotic resistance, using data for 116 countries from 2000 to 2018. The data sources included the World Health Organization, European Environment Agency and the World Bank.
The findings indicate antibiotic resistance increases with PM2.5, with every 10% rise in air pollution linked with increases in antibiotic resistance of 1.1%.
The association has strengthened over time, with changes in PM2.5 levels leading to larger increases in antibiotic resistance in more recent years. The analysis indicates antibiotic resistance resulting from air pollution was linked to an estimated 480,000 premature deaths in 2018.
A modelling of possible future scenarios indicates that if there were no changes to current policies on air pollution, by 2050 levels of antibiotic resistance worldwide could increase by 17%. The annual premature death toll linked to antibiotic resistance could rise to about 840,000. [Emph. added by BenIndy Contributor.]
The authors acknowledged limitations to their study. A lack of data in some countries may have affected the overall analysis, they said.
The study was observational, so could not prove cause and effect. Future research should focus on investigating the underlying mechanism of how air pollution affects antibiotic resistance, they said.
A second study published in the journal BMJ Mental Health found that exposure to relatively high levels of air pollution was associated with increased use of community mental health services by people with dementia. The long-term study focused on a large area of London with heavy traffic.
