A coalition of environmental, labor and public safety groups are calling on US lawmakers to reject the Trump administration’s move to eliminate a federal unit that investigates chemical accidents, citing risks to more than 170 million people who lives in zones at risk for such events. In a July 17 letter to leaders in the US House and Senate, the coalition said the White House plan to eliminate the US Chemical Safety and Hazard Investigation Board (CSB) comes at a time when there have been at least 105 “serious chemical disasters” reported so far this year.
