📋 Permit Cycle Assessment

The permit action (UIC Permit Renewal UICSWD1142 effective 2025-08-27) is fully explained by contemporaneous documents: a Sundry Notice requesting renewal, an AOR map showing no new wells, proof of landowner notifications, and explicit regulatory approval citing those submissions. The operator change (Grayson Mill to Devon) is documented via Form 15 and is a separate but necessary regulatory action for the permit to be effective under the new operator.
