Investigations have been launched following a massive fire at Intercontinental Terminals Company's Deer Park storage facility.
The blaze, which started on March 17, took more than three days to extinguish and engulfed 11 aboveground storage tanks containing a variety of hydrocarbons including naphtha and xylene.
Large plumes of black smoke could be seen covering parts of Houston and multiple orders were issued for community members to shelter in place. In addition, air quality warnings were also issued.
The US Chemical Safety Board has started an investigation into the cause of the blaze, which will include interviews as well as visiting the scene to collect evidence.
At the time of writing, the US Coast Guard remained unsure as to when the Houston Ship Channel, which was partly closed following the fire, would fully reopen as crews continue to clean up chemicals that seeped into the channel. Almost 20 miles of rubber barriers have been deployed to contain the spill.
In addition, the Labour Department's Occupational Safety and Health Administration has also launched an investigation.
Texas Attorney General Ken Paxton has also filed an environmental lawsuit against the company for air pollution in violation of the Texas Clean Air Act.
