Pollutants have been released from refineries operated by Exxon, Shell and other companies as torrential rains damaged storage tanks and other industrial facilities on the Texas Coast.
Shell told state regulators this week that a floating roof over a tank at its oil refinery in Deer Park, Texas, partially sank during the heavy rainfall. The company said 100 pounds of benzene and 100 pounds of toluene were released.
A similar event happened at Exxon Mobil Corp.’s refinery in Baytown, Texas. David Gray, a spokesman for the Environmental Protection Agency, said the company reported the release of 15 pounds of benzene. The EPA classifies benzene as a carcinogen. Toluene, a solvent, is less toxic.
A Shell spokesman did not immediately respond to a request for comment.
“This is an unprecedented storm, and we have taken every effort to minimize emissions and safely shut down equipment,” said Exxon spokeswoman Charlotte Huffaker. She said the Irving, Texas-based company was monitoring emission levels and was committed to complying with environmental laws.
