The explosion, reported on Monday, sent towering plumes of black smoke into the sky and was heard miles away, prompting emergency alerts for nearby communities. Officials have yet to confirm casualties, while response teams remain at the site to contain the situation and monitor air quality.

Witnesses have reported loud blasts that rocked car windows, per the Deep Dive.

Long-time resident recounts moment of explosion

A Port Arthur resident, John Beard, and an eyewitness said the Valero explosion was unlike anything he had experienced in nearly four decades in the industry.

He described the explosion as “tremendous” and mentioned seeing a “devastating fire.” He described the scene after the explosion was heard as “catastrophic.” The cars were scattering to drive away from the scene, per the resident.

Beard said that there was “a lot of mayhem, people in cars driving, wondering which way to go” as there was only a “highway that's the only way in and out.”

Beard further anticipated that the explosion may disrupt the entire refinery, citing other units catching fire and releasing massive amounts of gas.

He said, “It's probably going to cause a lot of those units to be down for a considerable period of time as they adjust to whatever this is that has happened.”

The Deep Dive shared another witness account where the resident described the presence of a pervasive rotten egg odor at the scene.

Videos and audio clips circulating on social media captured the intensity of the blast, with a loud shockwave heard seconds before flames and smoke engulfed parts of the facility.

“This comes at the worst possible time”

Mario Nawfal, a self-claimed journalist on X, wrote under Beard's account, “The facility processes roughly 395,000 barrels of crude oil per day, making it a critical piece of America's fuel supply chain. Port Arthur sits along the Gulf Coast refining corridor that handles nearly half of all U.S. refining capacity.”

Nawfal cites some consequences of the disruption that Beard predicted the explosion would produce. “This comes at the worst possible time,” he wrote.

The growing conflict between the United States and Iran has closed the Strait of Hormuz, forcing oil prices to skyrocket, reaching $100 already. Nawfal lists, “Iraq declared force majeure on its oil production. Qatar's LNG hub is damaged. Global crude is above $100.”

Nawfal further wrote about a potential shutdown of the refinery. “Even a temporary shutdown of a facility this size tightens domestic fuel supply at a moment when Americans are already paying $3.90+ at the pump,” he said.

The alert has also urged residents to remain in place until an “All Clear” message is issued by the emergency personnel.
