A means to prevent inadvertent intrusion on the source (e.g., the setting of a whipstock or other deflection device), unless the source is not accessible to any subsequent drilling operations, and c. The mounting of a permanent identification plaque, at the surface of the well, containing the appropriate information required by § 11.7.4 of this Part; 2. Notify the Agency, by telephone, of the circumstances that resulted in the inability to retrieve the source, and: a. Obtain Agency approval to implement abandonment procedures; or b.
