Published April 9, 2007. After gathering and incorporating comments from individuals, trade associations, companies, and numerous other entities, the CFATS regulation was published as an Interim Final Rule. Section 550 of the Homeland Security Appropriations Act of 2007 provided the Department with authority to promulgate “interim final regulations” for the security of certain chemical facilities in the United States. This rule establishes risk-based performance standards for the security of our Nation's chemical facilities, allows certain covered chemical facilities, in specified circumstances, to submit Alternate Security Programs (ASPs), and provides the Department with authority to seek compliance through the issuance of Orders, including Orders Assessing Civil Penalty and Orders for the Cessation of Operations.
