On April 17, 2013, a massive explosion at a fertilizer facility in West, Texas killed 15 people, 12 of whom were volunteer firefighters. This tragedy brought the dangers of chemical facilities to the national consciousness. On August 1, 2013, President Obama issued an Executive Order, which directed the EPA to issue new rules to prevent future chemical facility disasters. New rules were issued on January 13, 2017 but the Trump administration suspended and overturned them.
Chemical facility incidents continue to occur and often result in evacuations, shelter-in-place, closure of local businesses, injury to employees, community residents and sometimes death.
In 2021 the Biden administration will consider whether to issue a comprehensive disaster prevention rule that truly protects workers and communities from an estimated 150 serious incidents that occur each year in the U.S. We periodically update this list based on news reports.

It happened when two workers were extracting THC using cannabis that was soaked with butane and then heated to boil off liquid and create hash. The method is looked down on as unsafe by many in the industry because of the highly flammable nature of butane that is heated during the extraction process. At the time, New Mexicann Natural Medicine was fined $13,500 by OSHA and cited for at least 12 violations, which were considered serious by the state.”

Hurricane Laura incidents
August 27, 2020
“According to a WWNO/WRKF analysis of publicly-available reports and emails from the Louisiana Department of Environmental Quality (LDEQ), while the majority of facilities emerged unscathed from the Category 4 hurricane, nine out of the 138 facilities that were inspected suffered critical damage.”
Plains All American reported a leak of an unknown amount of crude oil from a 40,000 barrel storage tank. EPA said it received 31 reports of oil and chemical spills in the wake of Hurricane Laura.
Critical damage was reported at the Lotte Chemical plant in Lake Charles and Equistar Chemicals facility in Westlake. The Chemical Waste Management facility in Lake Charles, according to WWNO/WRKF, reported “severe” damage, including the potential “total loss” of a transfer facility.
The most significant incident occurred at the BioLab chemical plant in Lake Charles (below).A massive fire consumed this swimming pool chemical plant after being damaged by Hurricane Laura. The fire burned for two days and shut down Interstate 10. EPA found chlorine above detection limits in nine neighborhood locations. BioLab reportedly stores 835 tons of the chemical trichloroisocyanuric acid. A U.S. Chemical Safety Board investigation is ongoing, as of January 20, 2021.
In addition, according to New Orleans Public Radio, “The EPA is investigating potential damage at two Superfund sites in Louisiana — possible leaching of creosote-laden soil at American Creosote in DeRidder, and another incident at Marion Pressure Treating in Marion.”
Reform Austin reported that the pollution began before the Category 4 hurricane struck the Gulf Coast. “ “With Hurricane Laura threatening the Gulf Coast region, the oil refineries and petrochemical plants that stretch across the Houston area and Southeast Texas took their customary precautions of shutting down operations. In doing so, they released about 4 million pounds of pollutants into the air.”
Aug. 27, 2020
Valero reportedly released 840 pounds of sulphur dioxide around its Port Arthur operations during shut down procedure for Hurricane Laura.
Aug. 27, 2020
“In Texas, refineries were rushing to shut down as Laura came barrelling toward the coast. But shuttering these plants actually involves releasing millions of pounds of additional pollution. As part of shutdown procedures, these facilities often need to release and burn off (or flare) various unprocessed chemicals and gases,” reported Grist magazine. “In fact, when Laura made landfall in southeast Texas, a report by the Texas Commission on Environmental Quality showed that Motiva’s Port Arthur refinery, the largest oil refinery on the continent, had a chemical leak on a process line during the shutdown.” According to publication Reform Austin, “Motiva’s emissions totaled nearly 90 tons, including a half-ton of benzene. The plant reported releasing more hazardous pollutants during the hurricane than it did in all of 2018.”
Aug. 18, 2020
A tank fire was reported at Pasadena Refining Systems, adjacent to Buffalo Bayou. The product in the tank was “unknown,” according to a NOAA report.

The refinery has several regulated flammables, such as hydrogen, methane, ethanes, propanes, butanes, and pentanes. In addition, the refinery uses chlorine for algae control in cooling towers and hydrogen fluoride in the making of gasoline, which are also regulated substances.”
