A huge explosion early Wednesday has injured three people at a Texas chemical plant, and the strength of the blast shattered windows and damaged doors of nearby homes, startling sleeping residents.
Dark smoke continued to billow from the plant in Port Neches even after sunrise, at least five hours after the 1 a.m. blast, local news channel KBMT showed. Residents within a half mile of the petrochemical plant were under a mandatory evacuation order, and the Port Neches Fire Department encouraged everyone downwind of the smoke to shelter in place.
“We had some windows blow out and there are quite a few other places dealing with it, but not everyone,” Avenue Coffee Cafe co-owner David Pool told the Houston Chronicle while cleaning up damage. “The tenant closest to the explosion is perfectly fine.”
The explosion is the latest in a string of industrial incidents in the region. The Houston area saw three fires at chemical facilities in a month-long span in March and April — including an explosion at the KMCO plant in Crosby that killed a worker, as Houston Public Media’s Florian Martin reported. In July, more than 30 people were treated for minor injuries after a fire at an Exxon Mobil refinery in Baytown.
The plant is owned by the Houston-headquartered petrochemical company TPC Group, which said at 10 a.m. local time that “emergency responders are still working to bring the event under control, and are doing so as quickly and safely as possible.”
Those who were injured – two TPC employees and one contractor – were transported to a nearby hospital and to one in Houston, according to the company.
Images broadcast on KBMT show minor destruction to nearby homes caused by the blast, including ripped-off roofing shingles and mangled doors and windows. The local broadcaster showed footage captured by a doorbell camera, in which the dark sky is suddenly filled with bright white flames.
TPC has not said exactly what caused the massive explosion, saying only that it involved “a processing unit.”
The Texas Commission on Environmental Quality said it was responding to the explosion and is conducting handheld air monitoring. As of Wednesday morning, it was predicting “moderate” air quality in the Beaumont-Port Arthur area and said that “no impacts to water quality have been reported.”
The state environmental agency said it has requested EPA support, and federal personnel were heading to the site.
On its website, the TPC Group describes itself as “a leading producer of value-added products derived from petrochemical raw materials.”
A search of Texas Commission on Environmental Quality records shows that this year, TPC Group has been ordered to pay more than $378,000 in fines over multiple environmental violations at two facilities, in Port Neches and in Houston.
The largest penalty — more than $214,000 — was levied in January over issues at the Houston plant. Investigators found that the site was emitting more volatile organic compounds than allowed by law from its wastewater aeration ponds, among other violations including emissions of nitrogen oxides and carbon monoxide. The environmental regulator said that since then, the company had taken some steps to remedy those issues.
The most significant penalty involving the Port Neches facility this year was $13,688, issued in February. An investigator found the company “failed to prevent unauthorized emissions” by releasing 108 pounds of butadiene gas in June 2017 and 54 pounds several months later. Both releases “could have been avoided thorough better operational and maintenance practices,” the state environmental agency concluded. According to the agency’s records, TPC “generally denies” the
