Notices, Terminations & Suspensions

An approval document can only be issued if there is a specific approval citation in the Hazardous Materials Regulations (49 CFR). If there is no specific approval citation, the relief sought from the HMR must be in the form of a special permit.

The Office of Approvals and Permits may modify, suspend or terminate a special permit or approval.  This action is taken based on a finding that:

  • Based on circumstances, the permit or approval is no longer needed
  • The application contained inaccurate information, and the permit or approval would not have been granted if accurate information had been presented
  • The application contained deliberately inaccurate or incomplete information
  • The special permit or approval holder violated a term of the special permit or approval or an applicable requirement of the regulations demonstrating the holder is not fit to conduct the activity authorized
