SHREVEPORT, LA (KSLA) - Calumet says they've determined the cause of the chemical release on Thursday morning and issued an apology to residents in the community.
According to a statement released on Friday, the release was because of a piping failure. Samples of the pipe will be sent to a lab for analysis to determine why it failed.
The leak was discovered at 10:30 a.m. Thursday at Shreveport's Calumet Lubricants Company refinery located on Jewella Avenue. It happened on the west side of the refinery's campus.
The company says a total of 500 barrels of Isomerate were released.
Isomerate is a component of gasoline. The chemical can come out as a mist and create a vapor cloud. Concentrated, prolonged or deliberate inhalation of isomerate is commonly known as a naphtha or petroleum naphtha, may cause brain or nervous system damage, according to the materials data sheet. The chemical also is a skin and eye irritant.
According to the company, measures were taken to minimize the evaporation of Isomerate included both water mist and application of foam. Monitoring stations set up along the plant's fence line monitored the exposure levels of the hazardous materials. It was determined that not enough of the chemical was released to pose a threat to the community.
Authorities blocked off Jewella Avenue between Doris Street and Midway Avenue for Shreveport Fire Department crews to assist with clean up.
Calumet said that the released chemical has been cleaned up. The water used for the cleanup will be treated by the plant's onsite wastewater treatment system.
