Summary of Enforcement Case Status

Corrective Action Orders

This table shows the year-by-year status of enforcement cases involving a Corrective Action Order. A Corrective Action Order usually addresses issues resulting from an accident, spill, or other significant, immediate, or imminent safety or environmental concern. For example, in 2002 PHMSA issued 7 Corrective Action Orders. To date, 7 (100%) of these CAOs have been closed, and 0 (0%) are still open. Sometimes Corrective Action Orders require long-term actions by operators and thus may be open for extended periods of time.

Cases Involving Corrective Action Orders: 2002–2024(1)


The 2006 Pipeline Inspection, Protection, Enforcement, and Safety Act gave PHMSA the authority to include a new enforcement tool - the Safety Order, and a final rule was published on January 16, 2009. Training in the use of this new tool was completed in June 2010.
