1 Pa. Code § 35.132
Corrections in the official transcript may be made only to make it conform to the evidence presented at the hearing and to speak the truth. No corrections or physical changes shall be made in or upon the official transcript of the proceeding, except as provided in this section. Transcript corrections agreed to by opposing attorneys may be incorporated into the record, if and when approved by the agency head or the presiding officer, at any time during the hearing or after the close of evidence, as may be permitted by the agency head, or by the presiding officer before the filing of his proposed report, but not less than 10 days in advance of the time fixed for filing final briefs. The agency head or the presiding officer may call for the submission of proposed corrections and may make disposition thereof at appropriate times during the course of a proceeding.
