On Sunday evening, the plant initiated 'controlled ignitions' of remaining chemical trailers to "minimize the impacts to the community." The company said the remaining six containers storing organic peroxide products have now largely burned themselves out.

The company will open an assistance center at Crosby High School on Sept. 4 from 9 a.m. to 5 p.m. The company says they will provide help with temporary housing, filing claims and more.

Air quality testing will continue near the plant. Officials say so far there is no evidence of issues in those results, but nearby residents should not touch any ash they find from the plant.

Anyone with questions or concerns can contact the company 1-877-4ARKEMA.
