  "definition": "1. The area around a deep injection well that must be checked for artificial penetrations, such as other wells, before a permit is issued. Well operators must identify all wells within the AoR that penetrate the injection or confining zone, and repair all wells that are improperly completed or plugged. The AoR is either a circle with a radius of at least 1/4 mile around the well or an area determined by calculating the zone of endangering influence, where pressure due to injection may cause the migration of injected or formation fluid into a USDW.\n\n2. In the UIC program, the area surrounding an injection well that is reviewed during the permitting process to determine if flow between aquifers will be induced by the injection operation.",
