17 CFR 201.302: Record of hearings.

(a) Recordation. Unless ordered otherwise by the hearing officer or the Commission, all hearings shall be recorded and a written transcript thereof shall be prepared.

(b) Availability of a transcript. Transcripts of public hearings shall be available for purchase at prescribed rates. Transcripts of nonpublic proceedings, and transcripts subject to a protective order pursuant to § 201.322, shall be available for purchase only by parties; provided, however, that any person compelled to submit data or evidence in a hearing may purchase a copy of his or her own testimony.

(c) Transcript correction. Prior to the filing of post-hearing briefs or proposed findings and conclusions, or within such earlier time as directed by the Commission or the hearing officer, a party or witness may make a motion to correct the transcript. Proposed corrections of the transcript may be submitted to the hearing officer by stipulation pursuant to § 201.324, or by motion. Upon notice to all parties to the proceeding, the hearing officer may, by order, specify corrections to the transcript.
