2. Duke Kentucky shall respond to all requests for information propounded by
   Commission Staff, whether identified on the procedural schedule or otherwise, as provided in those requests.

   schedule shall also show good cause for being untimely. If the untimely motion is granted, the movant shall accept and abide by the existing procedural schedule.

2. Any hearing scheduled in this matter shall be held on the designated day or
   days and continue until called from the bench by the presiding officer.
