This report provides a high level summary of PHMSA's overall enforcement activity. It indicates how many enforcement cases are both initiated ("opened") and "closed" in a given year. PHMSA generally initiates enforcement cases in response to an accident or when an inspection identifies one or more probable violations of the pipeline safety statutes or regulations. These same cases are "closed" only after PHMSA has determined that the required corrective actions have been completed by the operator, and after any corresponding civil penalties have been paid. In some cases, the corrective actions are so extensive or the agency's monitoring period is so protracted that the case may remain open for months or even years. This means that many of the cases which are shown as "closed" in a given year may have been initiated in prior years.
|Year||Cases Initiated||Cases Closed|

Cases shown as closed in a given year may have been originally initiated in prior years, reflecting a multi-year time period of PHMSA follow-up.
