Review – CSB Updates Accidental Chemical Release Reporting Data – 6-1-26

Yesterday the CSB updated their published list of reported chemical release incidents. They added 38 new incidents that occurred since the previous version was published in March 2026. These are not incidents that the CSB is investigating; these are incidents that were reported to the CSB under their Accidental Release Reporting rules (40 CFR 1604) through END DATE. 

The table below shows the top five states based upon the number of reported incidents since the December update was published. In this case, with the short time frame since the last update, these were the only states that had reported incident.
