The House on Tuesday passed a bill by voice vote that would authorize the Department of Homeland Security to establish standards protecting chemical facilities from terrorism.

Standards developed under the legislation would not be disclosed publicly. But the information could be shared with state and local government officials with security clearances.

Additionally, chemical facilities would be audited and inspected to ensure compliance with the security standards outlined by DHS.
