Hazardous Materials: Risk-Based Adjustment of Transportation Security Plan Requirements

Summary: PHMSA, in consultation with the Transportation Security Administration (TSA) of the Department of Homeland Security (DHS), is modifying current security plan requirements applicable to the commercial transportation of hazardous materials by air, rail, vessel, and highway. Based on an evaluation of the security threats associated with specific types and quantities of hazardous materials, the final rule narrows the list of materials subject to security plan requirements and reduces associated regulatory costs and paperwork burden. The final rule also clarifies certain requirements related to security planning, training, and documentation.
