The 2017 Arkema plant explosion was an industrial disaster that took place during Hurricane Harvey in Crosby, Texas. Flooding from the hurricane disabled the refrigeration system at the plant which manufactured organic peroxides.[1][2]

A 2016 analysis done by the Houston Chronicle and Texas A&M[3] identified the Arkema facility as a facility posing a high potential for harm to the public. The analysis and subsequent series by the newspaper revealed major flaws in the regulation of chemical facilities in the U.S.[4]

2017 OSHA fines[edit]

In February 2017, OSHA issued safety fines regarding general safety and maintenance in the sum of $91,724.[5]


A 12-person ride out crew was assigned to manage the Arkema facility during the hurricane. According to the staff log, the employees were assuming minor flooding at the site.[6] Instead, flooding rapidly outpaced the company's disaster plans.

The plant flooded up to six feet deep, refrigeration was lost on August 29 and people within a 1.5-mile radius were evacuated the following day. Ignited by a runaway reaction of the organic peroxides, the first explosions took place around 1:00 am on August 31.[7]

As flood waters receded, officials decided to stop the waiting for the Crosby community of 2300 by igniting the remaining trailers, on Sunday, September 3, 2017.[8][5] The evacuation zone was lifted on September 4, 2017.[9]

In addition to the explosions, two wastewater tanks overflowed during the storm, releasing more than 23,000 pounds of contaminants that were carried by floodwaters into nearby homes. Noxious toxins including heavy metals, polycyclic aromatic hydrocarbons, dioxins and semi-volatile organic compounds have been identified in homes and soil in neighborhoods near the plant. It is uncertain what proportion of the chemical residues originated in gases released by the plant, and what proportion flowed out of the flooded wastewater tanks.[10]


On Thursday, August 31, 2017, the same day as the first fire, the U.S. Chemical Safety Board announced an investigation.[11] As of September 2017, this board was targeted for defunding by the Trump administration.[12]

The Environmental Protection Agency began formally asking questions of Arkema on September 7, 2017.[13]

Fight over public records[edit]

When Arkema North American CEO Richard Rowe[14] announced at a press conference that nothing could prevent an explosion at the Crosby facility, reporters requested documents about the plant.[15] The company repeatedly refused to disclose detailed chemical inventories, facility maps and other documents about the Crosby site to the public, citing concerns about terrorism.[16]

Many of the documents were later released to reporters after Freedom of Information requests.[6] Arkema's 2016 and 2017 detailed chemical inventories, also known as Tier IIs, remain secret.

Legal proceedings[edit]

In September, emergency workers who responded to the explosion filed a lawsuit against the plant for damage to their health caused by the negligence of plant management.[17][18][13]

In September, the civil attorney for Harris County (Houston area) has announced an investigation, and the criminal district attorney announced a pending lawsuit against Arkema.[19][20]
