President Barack Obama is ordering federal agencies to review safety rules at chemical facilities in response to the deadly April explosion at a Texas fertilizer plant.
In an executive order announced Thursday, Obama tasks agencies with identifying new ways to safely store and secure ammonium nitrate, the explosive chemical investigators say caused the blast. Agencies are also being told to determine whether additional chemicals should be covered by federal regulatory programs.
The massive explosion at the plant in the community of West, Texas, killed 15 people and leveled hundreds of structures, including three of the town's four schools. It also prompted new scrutiny of regulations at chemical plants and the risks posed by deadly chemicals to people living in surrounding areas.
While the explosion is still being investigated, preliminary findings have been presented to Congress. A report sent to the Senate Environment and Public Works Committee in June showed that the decades-old standards used to regulate fertilizer chemicals are far weaker than those used in other countries.
The report concluded that the safety of ammonium nitrate fertilizer storage "falls under a patchwork of U.S. regulatory standards and guidance -- a patchwork that has many large holes.
