Four cases, and the rule each one follows from.
Unmatched filings
Where the ID number on a filing does not match a utility we can identify, we list the filing as refused and give the reason.
Unsupported conclusions
We do not report a filing as passing or failing a water balance, because the source data does not support that conclusion.
Thresholds nobody set
We report a system as exceeding a threshold only where its regulator published one. Where none exists, we state that.
Our own errors
When we have published incorrect information, we publish the count, the cause and the correction.
