A new report from the EPA Office of Inspector General (May 6) highlighted that the U.S. Chemical Safety Board (CSB) is currently operating at only 40% board capacity (two out of five members), which restricts its ability to formally approve investigation reports and safety recommendations. The Clean Air Act Amendments of 1990 established that the CSB’s board shall consist of five board members, including a chairperson, who are appointed by the president and confirmed by the Senate. The board is responsible for major budgeting decisions, strategic planning and direction, general oversight of the CSB, and approval of investigation reports and studies. The CSB is challenged in meeting its mission to “drive chemical safety excellence through independent investigations to protect communities, workers, and the environment” while operating without a full board.
