Contra Costa Health (CCH) deployed a hazardous materials team to investigate a reported release of petroleum coke dust from Martinez Refining Company (MRC) about 11 a.m. Friday, Oct. 6.
The release ended soon after it was reported by MRC to Contra Costa County’s Community Warning System. CCH has not found evidence of any immediate risk to public health in surrounding communities.
MRC reported that the release began at 10:31 a.m. while workers were conducting maintenance, which was stopped due to the release.
CCH is aware of the Alhambra High School homecoming parade set for Friday evening. MRC confirmed there will not be additional maintenance on Friday, and they will use a different process to complete the work. [Emph. added by BenIndy.]
Following an assessment by our health officer, CCH believes the homecoming parade and other community events can proceed as planned.
CCH has asked the facility to provide a 72-hour report regarding the cause of the release, which will be posted at cchealth.org/hazmat.
[Note from BenIndy Contributor Nathalie Christian: The article makes need for independent air monitoring systems abundantly clear. Refineries can’t improve on what they can’t – or simply don’t – measure. Benicia’s Community Air Monitoring Program (BCAMP) is a tremendous resource worthy of our attention, acclamation and support.

It’s wonderful that BAAQMD staff will recommend that the Air District use a portion of these penalty funds in the Richmond community to support projects to improve air quality, but unspecific promises offer impacted communities very little in terms of holding both the refinery and the air district accountable to that easily made promise. Which programs? Exactly how much of the money?]
Air District fines Chemtrade $1,150,000 for air quality violations

Faulty monitors caused an underreporting of sulfur dioxide emissions
FOR IMMEDIATE RELEASE, July 27, 2023
SAN FRANCISCO – The Bay Area Air Quality Management District announced today that it has fined Chemtrade $1,150,000 for air quality violations at Chemtrade’s sulfuric acid manufacturing plant in Richmond. The penalty resolves seven notices of violation issued to Chemtrade for violations that occurred at its facility in Richmond.
The violations primarily involved Chemtrade’s continuous emissions monitoring system, which measures the plant’s sulfur dioxide emissions to ensure the facility complies with permit limits. Chemtrade failed to properly calibrate, operate and maintain this monitoring system over an eight- year period. This caused the monitoring system to under-report sulfur dioxide emissions by an estimated 33 percent per year on average.
“The substantial financial penalties for these violations send a clear message to Chemtrade that they must accurately monitor their sulfur dioxide emissions in compliance with all air quality regulations to help protect those living in the surrounding communities,” said Dr. Philip Fine, executive officer of the Air District. “Protecting air quality and the health of Bay Area residents is our top priority.”
Sulfur dioxide can have adverse impacts on the respiratory system and contributes to acid rain. The Air District’s audit did not find evidence that Chemtrade’s sulfur dioxide emissions exceeded the facility’s permit limits. But it did find that Chemtrade’s monitoring system was unable to reliably monitor the extent of the plant’s emissions.
The Air District’s Hearing Board previously issued an abatement order that required Chemtrade to address the problems with its monitoring system in April 2022. The assessment of this $1,150,000 fine adds a monetary penalty to that enforcement response. Agency staff will recommend that the Air District’s Board of Directors consider using a portion of these penalty funds in the Richmond community for projects to improve air quality.
In addition to the problems with monitoring system, the $1,150,000 penalty also covers violations for failure to use required abatement equipment to prevent emissions while unloading railcars at the facility; failure to properly start up the sulfuric acid plant, resulting in a visible yellow-brown plume from its main exhaust stack; and failure to report required information regarding these violations. All the violations that led to this settlement have been corrected.
The Air District issues Notices of Violation when facilities violate a specific air quality regulation or rule. Violators are generally required to respond to the notice within 10 days and submit a descriptionof the actions they will take to correct the problem. These actions can include shutting down certain operations immediately or changing operations or equipment to come into compliance.
The Bay Area Air Quality Management District is the regional agency responsible for protecting air quality in the nine-county Bay Area.
The health department said that hazmat teams did not immediately find evidence of coke dust in surrounding neighborhoods following the release. Coke dust is a black sooty substance chemically similar to charcoal that is created during the refining process.
The refinery first reported the release of coke dust, a byproduct of petroleum refining, at 6:04 p.m.
The Martinez Refining Company issued a statement on Facebook indicating that the release was contained within refinery grounds, and that there were not any “off-site impacts.” The statement said that the report was only issued out of an “abundance of caution,” and that the refinery “immediately contacted appropriate agencies and conducted community monitoring.”
“We apologize for any concern this may have caused our community,” the statement read.
After the previous release on July 11th, Contra Costa County health officials advised residents to avoid breathing the black dust released by the Martinez Refinery Company and to avoid making close contact with it until hazardous-materials teams were able to collect and test samples of the residue.
In that case, the health department ultimately concluded the release did not pose a long term health threat.

(KRON) — HazMat crews are responding to the Martinez Refining Company in Martinez after chemical dust was released into the air on Tuesday. The incident is being investigated by inspectors, according to the Bay Area Air Quality Management District. The agency said it is closely monitoring a petroleum coke release at the refinery and responding to complaints.
The agency is also documenting air quality violations and assisting first responders.
“Follow instructions from health officials,” the agency advised.
The Contra Costa Health Department’s HazMat team is also responding to the incident, which it described as the “release of dust” from Martinez Refining Company. Material from the release is visible on the ground in the surrounding neighborhoods, according to CCH.
Unlike a release of spent catalyst at the refinery last November that lasted from Thanksgiving night until the next day, MRC did notify CCH of the release at 10:22 a.m. Tuesday, according to CCH spokesperson Karl Fischer.
Tuesday’s release occurred at about 8:30 a.m. and lasted one minute. However, health officials expressed concern that it took nearly two hours for MRC to notify them.
“We are very concerned about the delayed notification to the Community Warning System,” said Contra Costa County Supervisor Federal Glover. “We are once again responding to a refinery incident and trying to determine the health impacts. We understand this is an ongoing concern for our community and timely notification is critical.”
“We do not yet know how much material was released, or how far it spread,” Fischer said. Sirens did not go off, as the refinery reported the release to the Community Warning System as a Level 1 incident, which doesn’t require the alarms. No area streets were closed for cleanup.
Like the November release, community members found dust particles on parked cars and on the ground.
Fischer said the material released was “coke dust,” which is a byproduct of the petroleum refining process. In November, the particles were “spent catalyst,” comprised of elevated levels of aluminum, barium, chromium, nickel, vanadium, and zinc, all of which can cause respiratory problems.
Health workers took samples for analysis Tuesday morning. CCH hazardous materials crews are investigating. Fischer said.
The public is advised to avoid breathing or coming into close contact with the material. CCH is collecting samples for lab analysis.
The refinery put out a statement on social media, describing the incident as a “brief release of Coke dust,” and saying that refinery personnel were conducting community monitoring.
The refinery urged anyone who had a claim or concern related to the release to contact a claims rep at 800-542-7113.
What is petroleum coke dust?
Petroleum coke is a carbon rich solid material that is a byproduct of oil refining. The substance is described as black in color and resembles soot. Health officials recommend using soap and water to clean impacted outdoor surfaces.
