Footnotes:
1Grade (or class) is assigned initially, but may be up- or downgraded at a later date
2May be significantly later than the initial report date if the leak was ever up- or downgraded to a different class
3Reports before 2020 often report barhole reading, not leak extent
4Status is usually “Pending” until repair or elimination; details, if any, are in the Notes column
5G3SEI plans only provided starting in SQ report for CY 2019
6Planned repair date field is often empty in the absence of a concrete timeframe (e.g. “Through GSEP”)
7The SQ Report for CY 2014, which was the first to require leak reporting, collects unrepaired leaks from all preceding years
8Only provided from CY 2019 onward and only for repaired leaks, an elimination plan being unnecessary
