Texas firefighters battle gas pipeline explosion in Deer Park, US

A towering flame gradually subsided Tuesday, morning, 17 September 2024, in the aftermath of a massive pipeline explosion after a vehicle drove through a fence and struck an above-ground valve, officials said. Deer Park officials said police and local FBI agents initiated investigations and found no preliminary reports that would suggest a coordinated or “terrorist” attack and that “this appears to be an isolated incident.” The investigation included efforts to learn more about the driver of a vehicle that was incinerated by the pipeline explosion as flames scorched the ground across a wide radius, severed adjacent power transmission lines and ignited homes at a distance. Police did not provide any information about the person’s condition.
An evacuation area included nearly 1 000 homes and initial shelter orders included schools.
Operators shut off the flow of natural gas liquids in the pipeline but so much remained in the miles of tubing that firefighters could do nothing but watch and hose down adjacent homes.
Deer Park Mayor Jerry Mouton Jr described intense heat from a fire that endured for more than 12 hours as ladder trucks showered houses from above. “A lot of the house structures that are adjacent to that are still catching on fire even though we’re putting a lot of water on them,” Mouton said at an afternoon news conference. A spewing flame still lit up the sky at sunset Monday.
Firefighters initially were dispatched at 09h55am, after an explosion at a valve station in Deer Park, adjacent to La Porte, rattled homes and businesses, including a Walmart. Deer Park officials said an SUV drove into the valve after going through a fence on the side of the Walmart parking lot.
At the news conference, officials said only one person, a firefighter, sustained a minor injury. Later, Deer Park spokesperson Kaitlyn Bluejacket said four people were injured. She didn’t provide details about the severity of the injuries.
Harris County Judge Lina Hidalgo said in a statement that 32 kilometres of pipeline between the two closed valves had to burn off before the fire would stop.
Anna Lewis, who was walking into the nearby Walmart when the explosion happened, said it sounded “like a bomb went off.” She said everyone inside was rushed to the back of the store and then taken across the street to a grocery store before being bussed to a community centre “It scared me,” she said. “You really don’t know what to do when it’s happening.”
Geselle Melina Guerra said she and her boyfriend heard the explosion as they were having breakfast in their mobile home.
“All of a sudden we hear this loud bang and then I see something bright, like orange, coming from our back door that’s outside,” said Guerra, who lives within the evacuation area.
Guerra’s boyfriend, Jairo Sanchez, said they’re used to evacuations because they live close to other plants near the highway, but he hadn’t seen an explosion before in his 10 years living there.
“We just drove as far as we could because we didn’t know what was happening,” Sanchez said.
Houston, Texas’ largest city, is the nation’s petrochemical heartland and is home to a cluster of refineries and plants and thousands of miles of pipelines. Explosions and fires are a familiar sight in the area, including some that have been deadly, raising recurring questions about the adequacy of industry efforts to protect the public and the environment.
Letting the fire burn out is better, from an environmental perspective, than trying to attack the flames with some kind of suppressing foam or liquid, said Ramanan Krishnamoorti, a petroleum engineering professor at the University of Houston.
“Otherwise it’s going to release a lot of volatile organics into the environment,” he said.
Still, there will undoubtedly be negative environmental consequences, including a release of soot, carbons and organic material, he said.
The pipeline’s owner, Dallas-based Energy Transfer, said air monitoring equipment was being set up near the plume of fire and smoke, which could be seen from at least 16 kilometres away at one point.
A statement from Harris County Pollution Control on Monday afternoon said no volatile organic compounds had been detected. The statement said particulate matter from the smoke was moderate and not an immediate risk to healthy people, although “sensitive populations may want to take precautions.” The Texas Commission on Environmental Quality said it was also monitoring the air.
Natural gas liquids are used primarily in the manufacturing of plastics and basic and intermediate chemicals, Krishnamoorti said.
The fire burned through nearby power lines, and the website PowerOutage.us said several thousand customers were without power at one point in Harris County.
Krishnamoorti said the area’s extensive pipeline infrastructure will have to be closely inspected for damage beyond the explosion site, though the fire “won’t be a major disrupter of supply chains.”
The Railroad Commission of Texas, which regulates oil and gas in the state, said its safety inspectors were investigating.
