IGNORING DISASTERSRefinery Fires, Other Chemical Disasters May No Longer Get Safety Investigations
The typically thorough investigative process of chemical disasters, conducted by the Chemical Safety and Hazard Investigation Board (CSB), will not happen in the case of the October 2025 disaster at a Chevron refinery in El Segundo, California, because of the federal government shutdown and lack of funding for the organization. The CSB will be eliminated entirely under the proposed 2026 federal budget, raising the risk of more, and more serious, chemical disasters, not just in the U.S. but around the world.
When fire erupted at the Intercontinental Terminals Co. bulk liquid petroleum storage terminal, large plumes of dark smoke billowed into the clear skies over Deer Park, Texas. Despite the efforts of site staff and local firefighters, more than 70 million gallons of petroleum products burned or were otherwise released into the environment over the following three days in March 2019.
Even while the fire was still burning, investigations began looking into what had happened and what was still happening. The Environmental Protection Agency tested air and water samples to determine how much pollution was being released – both to determine cleanup efforts and to assess fines. The Occupational Safety and Health Administration reviewed what had happened, but found that with no workers injured, there was no reason to investigate further or impose fines or other penalties on the company.
A third federal agency, the Chemical Safety and Hazard Investigation Board, often known as the CSB, got to work figuring out what had gone wrong, without assigning legal or financial responsibility, but rather seeking to learn from this disaster how to prevent future accidents. It’s an approach much like the National Transportation Safety Board takes toward airplane crashes, train derailments and other transportation-related tragedies: document what happened and identify every opportunity to prevent or reduce the chances of it happening again.
That deep investigative process reportedly will not happen in the wake of the October 2025 explosion and fire at a Chevron refinery in El Segundo, California, because of the federal government shutdown and lack of funding for the organization.
As scholars of chemical disasters, we believe this absence – and the potential for the board to be eliminated entirely under the proposed 2026 federal budget – raises the risk of more, and more serious, chemical disasters, not just in the U.S. but around the world.
Many Serious Incidents
The CSB investigation of that 2019 fire that burned 15 petroleum tanks at the Intercontinental Terminals Co., near the Port of Houston, yielded key recommendations to the company, OSHA and the EPA. They included necessary updates to safety management systems, the need for flammable-gas detectors to identify leaks, and remotely operated emergency shutoff valves so workers could close tanks containing hazardous material without exposing themselves to danger. The company has addressed the first recommendation and is reportedly working on the next two.
