Katherine Lemos, the chairperson of the U.S. Chemical Safety Board (CSB), has resigned from her position.
Shauna Lawhorne, a spokesperson for the CSB, confirmed Lemos’ departure, according to The Hill.
Lemos was the only member of the CSB appointed by the Trump administration and once she departs the only remaining members will be two Biden appointees. However, President Biden nominated a third member, Catherine J.K. Sandoval, in early June.
No official reason for the resignation was provided, but The Hill states that “Bloomberg reported Lemos cited ‘eroded confidence’ in the board’s ability to focus on its mission based on its ‘recent priorities,’ in a resignation letter to the White House.”
No completed investigations since September 2021
The CSB hasn’t posted any completed investigation reports on its website since it released final reports on the AB Specialty Silicones and Evergreen Packaging Paper Mill incidents on Sept. 24, 2021.
A public meeting on the investigation into the 2017 Loy Lange explosion was scheduled to take place on May 5, 2022, but was later cancelled.
