Cases Initiated: These are the yearly total of civil administrative enforcement actions that PHMSA has brought against pipeline owners and operators. It does not reflect those cases which the agency has referred to other Federal officials for criminal prosecution, nor does it include more egregious civil cases that are referred to the U.S. Department of Justice for judicial enforcement. The table shows the total number of Corrective Action Orders, Notices of Probable Violations, Notices of Amendment, Warning Letters, and Notices of Proposed Safety Orders issued in a given year.

Cases Resolved: These are the yearly total of PHMSA actions taken to resolve the various types of enforcement actions against operators. This includes the number of Corrective Action Orders, Final Orders, Notices of Amendment, and Consent Orders that have either been closed or issued in a given year. When an enforcement action is shown as "closed", PHMSA has verified that all of the corrective actions have been successfully completed and that any inadequate procedures that were identified successfully addressed. Enforcement actions shown as "issued" mean that corrective actions have been established that are acceptable to PHMSA, and that civil penalty assessments have been finalized.
