Subject:    BAAQMD oversight and enforcement of Regulation 12 – Rule 15, the Petroleum Refining Emissions Tracking Rule.

Dear Chair Rod Sinks, Vice Chair Cindy Chaves, Secretary Karen Mitchoff and Direrctors

I’m writing  as a 34-year resident of Benicia and a founding active member of the Good Neighbor Steering Committee, [“GNSC”] which was organized in 2000 to address public concerns and protect community health and safety as related to operations of the Valero refinery. I’d hope to express the following concerns at the Special Meeting held as a webinar today, but was unable to do so.

On August 1st, the Board received emailed letters from Jay Gunkelman and myself, outlining problems to date with refineries’ fenceline monitoring systems’ performance and reliability.

As you recall, Rule 15 was adopted in April, 2016. It required Bay Area refineries to install new, best technology fenceline monitoring systems, with raw data to be collected in real time at 5 minute intervals, and with a website provided for public access to that data.

After 4 years since Rule 15’s adoption, for the sake of public health and community safety, we would have expected by now that the Air District would have enforced standards for reliable performance of fenceline monitoring systems at all Bay Area refineries, and that data quality would be assured. Yet, to date, as per Rule 15 protocols, the District has not yet signed off on—e.g., given final approval of— the refineries’ fenceline monitoring and quality assurance plans. This is an unacceptable situation.

Today, we encourage the board and staff to fully address the various problems associated to Rule 15’s implementation at all Bay Area refineries. 

Pertinent to the Benicia community, Valero recently asserted that their Benicia refinery will be “the last man standing” among Bay Are refineries, and will continue to refine crude oil and produce petroleum products. Emissions tracking and fenceline monitoring will continue to be of particular concern to Benicians. The reliability of Valero’s fenceline systems’ performance is in serious doubt. 

In 2017, as per Rule 15 Guidelines, the GNSC submitted substantial comments to the District on Valero’s plans that had been created by Sonoma Tech for Valero.

In late 2019, the Benicia City Council voted to encourage Valero to get their fenceline systems installed and up and running before the District’s original deadline. Valero complied, installing 3 pathway systems and creating a public website to provide access to the data collected. Later, when public questions began to arise, Valero said that the new Hydrogen Sulfide monitoring system they’d purchased had never been field tested. After a year’s worth of data collection, data reliability remains questionable even for “signature” gases, including benzene. According to the Federal EPA’s Benzene Fenceline Monitoring Program, Valero’s benzene emissions were not only found to be the highest in the Bay Area; Valero’s total benzene emissions are four times greater than the four other refineries in the region.

It is implausible that there would be so few reportable detections, as the website routinely reports. Repeatedly, the website indicates that instruments are offline, or data is “pending final review.” Whose review? There is apparently no public access to archived data. Good science requires independent validation of data. Credibility of the systems and the data collection is at stake. Without independent review, public confusion and doubt about the sytems’ reliability will persist.

Right now, there is no independent, 3rd party data analysis required by the Air District. Yet verification of data for accuracy is crucial to public trustUnfortunately, in our casethe District has still not yet approved Valero’s fenceline monitoring system plan including the required quality assurance plan as mandated by Rule 12-15.

In the meantime, concerned Benicia residents formed a non-profit, incorporated in 2019, to provide an independently operated, community-based air-monitoring station for Benicia, called Benicia Community Air Monitoring Program. The system will be operated by solar, and will meet international standards for data quality. (Funding was appropriated through GNSC’s urging amendments to the  Settlement Agreement negotiated with Valero and City of Benicia.) We expect the new station will be operational by the end of 2020.

How is it possible that a small community group in Benicia can locate, configure and install an array of air monitoring equipment in less than a year, while the refineries in the Bay Area are still installing technologically inferior fenceline systems four years after they were told by the BAAQMD that these systems had to be approved and proven reliable, thus producing accurate data by now? 

I reiterate my request made in my letter of August 1st: 

We ask the Board to compel Valero to present all of the data associated with these systems to the public as soon as possible. In addition, we would like to see all raw data produced by the fenceline system at Valero so that it can be reviewed by independent experts. We ask that the  public have access to all District staff comments on refineries’ monitoring plans including quality assurance plans.

Thank you for your timely consideration of these matters.

Solano County Says Valero Benicia Refinery Violated State Regulations in March Shutdown

Valero Benicia Refinery facing stiff fines

Solano County inspectors documented a long list of shortcomings and inadequate procedures at Valero’s Benicia oil refinery that contributed to a major pollution release from the facility earlier this year, newly released county documents show.

The county’s Department of Resource Management documented violations of eight separate state regulations. The infractions included failure to fix important sensors in a refinery furnace unit, infrequent inspections of key equipment, and failure to have an operating plan in place to deal with unexpected refinery conditions.

Solano’s probe relied in part on Valero’s root cause analysis of the shutdown, which found that one of the worst refinery incidents in the Bay Area in years was caused by a mistake made months earlier.

Both reports focused on tubes in the refinery’s furnace that heat up crude oil before it’s routed to other parts of the facility for processing. County and refinery officials say those furnace tubes were damaged during maintenance work last November, which caused the devices to fail and contributed to the plant’s malfunctions in March.

The Valero complex ended up belching out a massive amount of black sooty smoke, which led to health concerns for people living nearby.

The refinery’s subsequent closure contributed to a statewide spike in gasoline prices and prompted investigations by several government agencies, renewing attention on the refinery two years after a power outage caused a major release of toxic sulfur dioxide in the area.

Valero spokeswoman Lillian Riojas declined to comment directly on the company’s violations. Instead, she pointed to the company’s May filing with the Securities and Exchange Commission in which it reported it’s facing more than $342,000 in fines in connection with the incident. The company told the SEC it expects to face $242,840 in proposed penalties from Solano County and $100,000 from the Bay Area Air Quality Management District.

Valero’s root cause analysis, completed in July, examines a series of problems that led to the refinery malfunctions.

Company inspections during the refinery shutdown found that furnace tubes were bulging and leaking. Valero says when the facility was restarting a unit last November, a safety valve improperly “lifted,” allowing crude oil to bypass one of the refinery’s furnaces.

Valero says “it was not appreciated at the time” that allowing the bypass “exposed the furnace tubes to elevated temperatures.” Extreme heat gradually deformed the tubes and allowed a solid substance called petroleum coke to form inside. Valero’s analysis concedes that the deteriorating conditions were “not timely identified and mitigated, leading to the tubes’ subsequent failure” and the March refinery malfunctions.

Solano County’s investigation reported that carbon monoxide and oxygen sensors in the refinery furnace were not operational for at least three years.

“Proper functioning sensors would have provided an indication that the furnace was malfunctioning to Valero staff, allowing them to act sooner to correct the condition and prevent additional release,” said Terry Schmidtbauer, the county’s assistant director of resource management, in an email.

“The issue with the furnace upset the system,” Schmidtbauer said.

Those system issues became more evident in early March as two other refinery components experienced problems. One was a fluid coker, which heats up and “cracks” the thickest components of crude oil processed at the refinery. Another, a flue gas scrubber, removes fine particles before gases are released from the facility’s smokestacks.

Malfunctions with those devices led to an increase in carbon monoxide levels, according to Valero, To reduce those levels, refinery crews ended up increasing the temperature on the furnace tubes, thus accelerating their deterioration.

There was little liquid in the tubes, which puts them at risk of damage, according to Professor Eric Smith of Tulane University’s Energy Institute, who specializes in refinery operations.

“One result is thermal degradation of the metal tube,” said Smith, who reviewed company and county findings. “Another effect is that the liquid that does make it through the tube is converted into petroleum coke.”

That dynamic led to the release of sooty smoke and resulted in elevated levels of particulate matter and a health advisory.

County inspectors discovered several problems with lines that carry petroleum coke. On the day the refinery was shut down, one was leaking. Valero staff told Solano officials in April another line had failed five times in the last three years.

The county’s Department of Resource Management has ordered Valero to make a series of changes, some of which it has already completed. They include orders to reduce petroleum coke releases, new procedures for preventing the overheating of furnace tubes and increased training.

Solano County’s Schmidtbauer said the department was still assessing what penalties it will levy against the refinery.

Local air regulators issued 12 notices of violation against Valero. Ralph Borrmann, a spokesman for the air district, said the agency’s probe is not yet complete.

An investigation by California’s Division of Occupational Safety and Health, Cal/OSHA, is expected to wrap up in the coming weeks, according to agency spokesman Frank Polizzi.

Bay Area Air District lawsuit: Clearing out the file cabinets, but not necessarily the air

Lawsuit by Agency Whistleblower Alleges Widespread Document Destruction at Bay Area Air Quality Management District.

A veteran employee of the Bay Area Air Quality Management District has filed a lawsuit charging that the district destroyed important public records about air pollution, then fired him because he objected.

Through interviews and court documents, Michael Bachmann and coworker Sarah Steele describe an agency culture that accommodated large polluters, shredded records of emission violations, withheld such documents from the public, and violated a legal agreement to preserve its data. A spokesperson for the district declined to comment on the case.

Bachmann had worked for the air district for more than a dozen years when he was asked, in 2014, to take charge of a massive overhaul of the agency’s records. The district was planning to move its headquarters and wanted to inventory, streamline, and digitize its files in preparation for the move.

To help with this task, Bachmann hired his longtime friend Steele, who had experience creating and managing records systems. While she organized paper and microfilm documents, he worked with photographic images stored on computers, creating a digital system to organize and digitize them so they would be searchable.

“My goal was to make sure everybody could see the history,” Steele said. Air District planners need records of past experience to guide future decisions about controlling air pollution. In addition, the district is required by law to retain many types of documents as public records. Steele said part of her motivation for this work came from growing up in El Sobrante, unaware of how pollution from nearby refineries was harming the health of her community. “So few people are aware of the horrific pollution going on in our backyards.” She said it’s important for people to know the history of pollution on a particular piece of land — such as the site of the notorious Berkeley polluter, Pacific Steel Casting, which recently closed.

Bachmann is now restricted from discussing his suit by a recent court-imposed confidentiality rule, but he told his story in interviews before the rule was put into effect. His attorneys, Gary Gwilliam and Jayme Walker, provided additional details in the brief they filed in August 2017 in Contra Costa Superior Court against the district and six senior staff members. Steele, who also was fired in February 2016, was originally part of the lawsuit, but in June of this year she accepted a cash payment to settle her case. Steele and Bachmann, now a couple, were struggling financially after both losing their jobs, and Steele wanted to be free to talk about the case.

As Bachmann and Steele worked on organizing the records, they began noticing things that disturbed them. In the summer of 2015, she said, “giant dumpsters began to appear” in the office. When Steele looked in the dumpsters, she found, among other things, reports of refinery “flaring” incidents, notices of violations of air-pollution standards, and documents pertaining to current litigation — all records that she thought should be kept. In August, according to the lawyers’ brief, an employee in the enforcement division also told Bachmann that documents related to litigation against Pacific Steel Casting were being improperly destroyed.

At around the same time, Steele was working on sending paper and microfilm records to a contractor to digitize. According to the lawyers’ brief, one day air district Director of Enforcement Wayne Kino and attorneys Brian Bunger and Bill Guy “approached [Steele] in an aggressive manner and told her they wanted to destroy microfiche documents containing many records of violations of air quality.” Steele thought that request was illegal and reported it to Bachmann.

In November, Bachmann told senior executives that records were being illegally destroyed and asked that they send documents to him first, rather than putting them straight into dumpsters. In an interview before the confidentiality order was imposed, Bachmann said Bunger overruled this request. He quoted the lawyer as saying, “If staff accidentally destroys these records, that’s OK, because they can only hurt us in the long run.”

Meanwhile, Steele said, boxes of paper and microfilm documents were being shipped to a storage facility in Richmond. But some records were withheld from these shipments, sometimes with explanations, sometimes not. She said the process seemed “haphazard.” She continued to send records to be digitized, but senior officials told her not to digitize certain documents, including records in one huge, locked cabinet that Steele nicknamed the “magic cabinet.”

Steele said Rochelle Reed, public records coordinator, stated in a deposition to the court that the cabinet had not been opened in more than ten years. After the cabinet was moved to Richmond, a staff member sawed off the lock. Inside, Steele found records of asbestos pollution, refinery flares, inspection reports, and settlements between the air district and companies that had been charged with violations. She expressed concern that these documents had not been made available for public records requests. Asked if she felt the district was withholding information from the public, Steele said, “Hell, yeah.”

Another former air district employee, who asked not to be named, agreed that the district had mishandled public documents and destroyed many that should have been kept, but disagreed with Bachmann’s and Steele’s suspicions that this was being done intentionally to keep information from the public. The employee, who was familiar with the document-handling process, expressed the view that rather than “a conspiracy,” the records mishandling was due to “laziness and ineptitude.”

That person, however, also reported having the impression that senior air district officials were reluctant to clash with industrial polluters. If the district were to impose large fines for air-pollution violations, for example, “the refineries would fight tooth and nail — and they have the best lawyers.” The former employee said district officials “want to work with industry, to be on their good side, [to have] a symbiotic relationship.”

Steele believes this cozy relationship interferes with the public’s right to know about air pollution issues.

In December 2015, Bachmann made another disturbing discovery. Over the summer he had downloaded all the photographic images of documents from agency computers. Since then, he had developed a software system for digitizing them to be searchable. But at the end of the year, when he went back to the computers to double check, he found that thousands of these images had disappeared. They included records of violations of air quality standards, complaints and actions taken, asbestos records, and communications between executives and industry. Gaps in numbering showed that documents were missing.

In January 2016, Bachmann reported this to air district senior staff. His supervisor, Eric Stevenson, said later in a court deposition that Bachmann had been “ruffling feathers” of executive management: “He wanted … to be more in control of the documents system as opposed to … allowing the divisions to maintain control of that,” Stevenson said. Under further questioning he added that Bachmann wanted that control because “there was the potential that documents of records could be destroyed.”

Air district employees soon received a flyer with their paychecks reminding them that the office move was imminent and encouraging them to “clear out unwanted/unneeded items.” The flyer specified that “confidential documents” should go into shredder bins and other materials into recycling containers, with no direction about which records to retain. The flyer promised a pizza party to the division with the best-cleaned-out office.

The following month, Bachmann was summoned to a disciplinary meeting where he was told he was being suspended for a week without pay for violating the agency’s vehicle-use policy. Officials said he used an air district car in his commute, a widespread practice specifically allowed in the vehicle-use policy, Bachmann said.

His absence gave agency officials an opportunity to second-guess his work. “When a government employee is suspended without pay,” he noted, “the agency gets access to your computer.” When Bachmann returned after a week, he found that his whole software system for digitizing records had been wiped from his computer — along with all the digitized documents. Fortunately, he said, he had stored all the information on a hard drive and backed it up in the cloud.

On the same day Bachmann was suspended, Steele was told she was being let go because the project was finished. Yet after Steele and Bachmann were gone, she said, the district hired a contractor to continue the work they had been doing.

Even before he returned from his suspension, Bachmann was suspended a second time, this time with pay. However, he maintained access to a security camera at the Richmond storage facility. He showed the Express pictures he said were stills taken by that camera in May 2016. The pictures showed records chief Reed directing a crew that was dumping boxes of stored records into bins, then wheeling them out to a truck labeled “Shred-It.” This despite a 2001 agreement in San Francisco Superior Court in which the air district committed not to destroy any public documents without keeping a record of them.

Bachmann was finally fired in August 2017. At stake for him, as a career employee, was not only his salary but also his access to health care and other retirement benefits — although his retirement income is secure in the state employee pension fund. Reasons given for his firing were “misconduct,” “insubordination,” and “dishonesty.” The air district claimed he had misrepresented his military service and education on his employment application, but Bachmann said he has documents verifying these records.

As a career employee, Bachmann was entitled to due process in a “Skelly hearing,” named after a court case that established this right. According to law, the officer conducting the hearing is supposed to be impartial. But Steele pointed out that Bachmann’s hearing was conducted by Jeff McKay, one of the district officials charged in the lawsuit with destroying records.

The lawsuit is moving slowly, but scheduled to go to trial in December. So far the court has taken depositions from eleven air district staff members. Last April, Walker said, it imposed a fine on the district for “abusing the discovery process and not producing documents that they should have produced.”
