Chevron’s El Segundo refinery has a historical past of security, environmental violations

The explosion and hours-long hearth at Chevron’s refinery Thursday night time in El Segundo deeply unnerved communities within the South Bay.

The blast despatched shock waves all through the refinery grounds, allegedly injuring not less than one employee, and jolting residents so far as a mile away. A 100-foot-tall pillar of fireside forged an orange glow over the night time sky. And towering plumes of smoke and acrid odors drifted eastward with the onshore winds.

Whereas native regulators are investigating the fireplace, environmental advocates lament that federal security businesses seemingly gained’t be becoming a member of within the effort to search out the reason for Thursday’s explosion — maybe stopping related hazardous chemical releases sooner or later. The incident was one of the crucial perilous occasions within the refinery’s 114-year historical past, including to a protracted listing of environmental and security violations, in accordance with public data reviewed by The Occasions.

Most workers on the Occupational Security and Well being Administration, the federal company tasked with investigating office security, just isn’t working due to the continued federal shutdown. The U.S. Chemical Security and Hazard Mitigation Board, which determines root causes from harmful chemical releases, can also be furloughed and will lose its funding due to proposed funds cuts by the Trump administration.

“The Trump administration has defunded the Chemical Security board, and the federal authorities is shut down proper now,” mentioned Joe Lyou, a resident of close by Hawthorne and president of the Coalition for Clear Air, a statewide nonprofit. “So there’s a excellent chance we’re by no means going to know what actually brought on this, as a result of the specialists in figuring these items out are not there to try this.”

With out clear solutions, labor unions are fearful {that a} related catastrophe may endanger hundreds of employees at California’s 15 refineries, that are largely clustered in Southern California and the Bay Space.

“Firms are making billions in income and nonetheless are making it practically unattainable to ensure we’re secure from horrible disasters,” mentioned Joe Uehlein, board president of the Labor Community for Sustainability. “In California, we’ve seen horrific accidents to employees and tens of hundreds of residents have needed to search medical consideration in refinery accidents. This time, we bought fortunate.”

The Chemical Security Board has recognized causes of scores of refinery incidents over its historical past, together with the 2015 explosion on the ExxonMobil refinery in Torrance that injured not less than two employees.

In that incident, the board’s investigation discovered a number of security failures, together with a severely eroded security valve that allowed flammable gases to dangerously seep into undesirable areas. The board additionally found that a big piece of particles nearly struck a tank of hydrofluoric acid, which may have resulted in a lethal launch of the extremely poisonous chemical, resulting in stress to stop utilizing the chemical.

However, for the Chevron refinery explosion, there is no such thing as a assure such an investigation will happen. The Trump administration proposed eliminating the funds for the Chemical Security Board this fiscal 12 months, beginning Oct. 1, sunsetting the 27-year-old federal company. Environmental advocates say that could be a mistake.

“They’re undermining our skill to stop these accidents by taking away the accountability mechanisms within the federal authorities,” mentioned Lyou. “That’s an enormous concern. It’s not politics. Democrats and Republicans reside across the Chevron refinery, they usually each wish to be sure that the refinery is working safely.”

Within the absence of federal regulators, the South Coast Air High quality Administration District is investigating potential violations of air high quality guidelines and allow situations. The refinery may even be required to submit a report analyzing potential causes and gear breakdowns inside 30 days.

Up to now, the air district has mentioned the fireplace originated within the refinery’s ISOMAX hydocracking unit, which makes use of hydrogen to refine oil into jet gasoline and diesel. The refinery’s air displays detected a spike in airborne chemical substances after the fireplace broke out, however air district officers say situations returned to regular ranges after a couple of hours.

Environmental advocates say the extent of the fallout will not be identified till there’s a bigger examination of air high quality displays.

“I used to be very stunned that the air district reported they weren’t seeing terribly excessive ranges of air pollution,” mentioned Julia Could, senior scientist for California-based nonprofit Communities for a Higher Atmosphere. “Typically in an enormous refinery hearth like this, it goes straight up. However then the smoke comes down in different areas. And that’s loads of air pollution that’s going someplace.”

The Chevron facility had been cited quite a few instances for environmental and security violations, in accordance with native and federal data.

The South Coast Air High quality Administration District has issued 13 notices of violations during the last 12 months, and 46 within the final 5 years. Most not too long ago, on Sept. 22, the air district cited the ability for a big chemical leak and failing to maintain its gear in correct working situation.

In August, Chevron representatives had additionally requested the air district for leniency in assessing compliance with air high quality guidelines whereas it was working to take away undesirable buildup inside its furnace tubes — situations that they mentioned risked gear overheating and probably failing.

OSHA data present the company performed not less than 15 inspections on the Chevron refinery in El Segundo during the last decade, figuring out 17 violations.

In September 2023, OSHA issued citations associated to warmth sickness prevention necessities, ladderway guardrails and a failure to conduct an intensive hazard evaluation — an inner evaluation supposed to regulate fires, explosions and chemical releases.

In October 2022, after conducting a deliberate inspection of the Chevron refinery, OSHA data present the company recognized a “severe” violation of an company normal requiring employers to “develop, implement and keep secure work practices to stop or management hazards,” corresponding to leaks, spills, releases and discharges; and management over entry into hazardous work areas.”

Throughout the federal government shutdown, it’s unclear if OSHA’s pared-down workers will likely be investigating Thursday’s refinery hearth. An OSHA media workplace telephone quantity went straight to a recorded message stating that the road just isn’t being monitored and “on account of a lack of funding, sure authorities actions have been suspended and I’m unable to answer your message presently.”

For some environmentalists, the Chevron refinery hearth has underscored why it’s essential to transition away from fossil fuels altogether.

“They [the refineries] have nice employees and nice hearth departments to reply, however that is an inherently harmful operation that handles lots of of hundreds of barrels per day of flammable explosive supplies below excessive temperature and excessive stress,” mentioned Could, the senior scientist for Communities for a Higher Atmosphere.

“When one thing goes unsuitable, you’ll be able to have a runaway hearth. They did an important job at getting it below management. However do we actually need antiquated soiled vitality in our communities?”
