CSB Cuts Report Back-Log by Two-Thirds in Just the Last Twelve Months

U.S. Chemical Safety and Hazard Investigation Board (CSB), July 24, 2023

The U.S. Chemical Safety Board (CSB) announced that it has released twelve final investigation reports since July 2022, thereby eliminating two-thirds of the agency’s backlog during the last twelve months.

CSB Chairperson Steve Owens said, “When I became the Interim Executive in late July 2022, the CSB had an enormous backlog of seventeen open investigations, some dating as far back as 2016. Reducing the backlog so significantly as we have done so quickly has taken an extraordinary effort by every employee at the CSB, working together as a team. The CSB has never before issued so many reports in such a short period of time.”

Owens became the CSB Interim Executive when the former CSB Chairperson resigned last year. He was nominated at that time by President Biden to be the new Chairperson and confirmed by the U.S. Senate in December 2022.

Additionally, the CSB is on track to close and issue final reports for the remaining five open investigations by the end of this calendar year. This would completely eliminate the long-standing backlog.

Board Member Sylvia Johnson said, “I look forward to our continued productivity. As a team, we have worked extraordinarily hard to meet our deadlines and I know that we will continue to issue reports, safety videos and onboard new staff as we close out this year.

Board Member Catherine Sandoval said, “This has truly been a landmark achievement for the CSB. I am honored to work with such a dedicated group of people and looking forward to continuing to advance chemical, environmental , worker, and public safety.

On July 27th at 2:00 pm the CSB will provide updates on a number of its recently released investigations. You can view our 4th quarter public business meeting here.
