Benicia asthma rate well above average – statistics

By Roger Straw, March 27, 2019

Yesterday, Benicia  Mayor Elizabeth Patterson circulated an E-Alert titled “Asthma Rates in Solano County.” She supported claims being made that Benicia asthma rates are high, showing a detailed chart published by the California Department of Public Health.

The Mayor was challenged, evidently, on the accuracy of claims that Benicia asthma rates are at 30%.  Patterson wrote, “Questions are being raised about the asthma rates in Solano.  A quick search to confirm the stated 30% corrects that information below. However, in other studies the rate was listed higher.  Here is the  link.”

Today, Mayor Patterson sent another email clarifying her original source for the 30% figure: a Solano County report, “Asthma Rate by Zip Code.”   That March 2016 report showed “Prevalence of ASTHMA among Solano County adult residents is 2.2X the prevalence among all Californians.  Solano County: 30.1%, California: 14.2%.  Source: Behavioral Risk Factor Surveillance System, Centers for Disease Control and Prevention.  Additional data analysis by CARES. 2011-2012.”

Patterson wrote, “You will see where I got my original 30% rate. Now [2018] the county shows approximately 24% for Benicia and so we are talking about a 6% difference.  The data from the County is based on data from medical facilities.  We have done presentations at the City Council and posted the information with various caveats. County Health is doing a good job and the information is getting updated. But at the end of the day, we have unhealthy air that contributes to asthma, cardio-vascular problems and diabetes.“

SF Chronicle editorial: On Benicia Refinery Safety

Clear the air

Benicia residents with respiratory ailments were warned to stay indoors for five hours Sunday because the Valero Refinery was filling the air with heavy smoke. The warning was lifted when Valero announced it was temporarily shutting down the refinery process.

Now the mayor has renewed her call to pass a Benicia industrial safety ordinance similar to the one that has guided refinery operations in Contra Costa County for decades. For the sake of clean air for all, the Benicia City Council should do so.

Benicia Mayor Elizabeth Patterson first sought a city safety ordinance after a May 5, 2017, power outage sent flames roaring from the refinery’s stacks and spread pollution into the air, prompting shelter-in-place and evacuation orders for the community of 28,000. Within weeks of that event, Valero was fined by regional regulators, and two state agencies and Solano County adopted regulations modeled on the Contra Costa County ordinance.

The Benicia City Council, however, voted 3-2 to monitor implementation of the county’s new ordinance rather than adopt its own. Now Patterson is trying again.

She has suggested the council seek third-party review of the draft ordinance, which would require refinery reports be shared with Benicia, not just the state and county, and include a way to collect fees to cover the city’s costs of review.

While air quality is an ongoing community concern, the refinery’s latest problem began two weeks ago and so far has netted Valero seven violations from regulators. A third of Benicians have respiratory ailments — three times higher than the state average. For them, emissions are a health concern.

“There’s a saying,” Patterson said. “You either have a seat at the table or you’re on the menu.”

After Weeks of Issues, Valero’s Benicia Refinery to Temporarily Shut Down

The Valero refinery is performing a controlled shutdown to “improve conditions and minimize risk,” according to a statement from Benicia city officials. The shutdown could last multiple days and result in visible flaring.

Earlier Sunday, city officials issued an advisory notice for residents with respiratory issues to stay inside after a two-week-old problem at the Valero refinery worsened.

But now that the refinery is shutting down, city officials and Solano County health officer Bela Matyas says the air quality is safe for residents.

The problem the Valero refinery began on March 11 when a malfunction involving one of the refinery’s units led to the release of petroleum coke dust.

A Valero representative said then that refinery’s flue gas scrubber was “experiencing operational issues.”

The releases prompted local air regulators to issue seven notices of violation against the refinery. 

Those problems eased after a few days but continued intermittently, air district officials said.

On Saturday several Benicia residents posted comments on the social media site, Nextdoor, expressing concerns about what appeared to be more black smoke coming from Valero’s stacks.

On Sunday, the particulate matter in the air increased.

“The concentration of particulate matter has become significantly higher over the past day. The emissions contain coke, a by-product of the refining process that is made up primarily of carbon particles,” the city’s statement says.

Benicia officials said testing of the coke dust released so far did not show heavy metals at harmful levels but warned that breathing in air from the releases could worsen underlying respiratory conditions like asthma.

“Inspectors are on scene working with the facility and with Solano County and making a determination if additional violations will be coming,” said Lisa Fasano, a spokeswoman with the Bay Area Air Quality Management District.

The Air District also deployed a monitoring van to drive throughout Benicia to “gather ground level emissions data.”
