Types of Releases?
Aboveground Storage Tank owners or operators are required by law to report confirmed, threatened or suspected releases. The type of release will determine the reporting requirements.
There are two different types of releases, “Confirmed” and “Suspected or Threatened”. All releases must be reported but depending on the type of release reporting requirements will vary.
- A “Confirmed” releases is defined as “verification that a substance has been discharged from the AST system components into the waters of the state or has escaped from secondary containment.”
- A “Suspected or Threatened” release means a potential exist that an unplanned or unintentional discharge of substance from an AST system may have occurred or, based upon information obtained from any source, may occur, such as substance from the AST observed in the secondary containment structure, testing, sampling, monitoring results from a release detection method or observed unusual operating conditions of an AST system. Releases from an AST into secondary containment should be treated as a suspected or threatened release.
