c) Waiver of filing requirements

1. 1) Requests for waivers from these filing requirements shall be filed with the Commission at least 60 days prior to the filing of the plan for which the waiver would be effective, if granted. Requests for waivers will be acted on by the Commission or, if directed by the Commission, the Manager of the Administrative Law Judge (ALJ) Division or his or her appointed representative (Administrative Law Judge) and shall be in writing.

2. 2) A request for a waiver of any of the provisions of these filing requirements shall be in writing, verified, and must set forth the specific reasons in support of the request. The Commission or ALJ (where directed by the Commission) shall grant the request for a waiver upon good cause shown by the carrier. In determining whether good cause has been shown, the Commission or ALJ shall consider, among other things:

   1. A) Whether other information the carrier would provide if the waiver is granted permits the Commission Staff to review the filing in a complete and timely manner;
   2. B) The degree to which the information that is the subject of the waiver request is maintained by the carrier in the ordinary course of business or is available to it from the information that it maintains; and
   3. C) The expense to the carrier in providing the information that is the subject of the waiver request.
3. 3) Proprietary and confidential information. Any data, information or studies that is confidential, proprietary or trade secret in nature shall be so marked by the carrier. The carrier shall separate from its filing that information marked as confidential, proprietary or trade secret in nature from the material that is to be made public.
