These are lists of interested parties that the Office of the Secretary prepares in investigations that facilitate the exchange of documents among the parties of record. Interested parties are expected to serve other interested parties on the list with copies of all documents filed with the Commission. In certain proceedings, the Office of the Secretary maintains two service lists: one that lists the interested parties they may receive only documents containing publicly available information, and a second list that contains the names of interested parties who may receive documents that contain business proprietary/confidential business information obtained under an administrative protective order.
