Service list. The APO/Dockets Unit will maintain and make available a public service list for each segment of a proceeding. The service list for an application for a scope ruling is described in § 351.225(n).

With the exception of a petitioner filing a petition in an investigation, all persons wishing to participate in a segment of a proceeding must file a letter of appearance. The letter of appearance must identify the name of the interested party, how that party qualifies as an interested party under § 351.102(b)(29) and section 771(9) of the Act, and the name of the firm, if any, representing the interested party in that particular segment of the proceeding. All persons who file a letter of appearance and qualify as an interested party will be included in the public service list for the segment of the proceeding in which the letter of appearance is submitted.
