210 Pa. Code § 69.211
When the Prothonotary receives a written communication that evidences an intention to appeal an adjudication of a state administrative agency but does not conform to the rules for an appellate petition for review, the Prothonotary shall time-stamp the written communication with the date of receipt. The Prothonotary shall advise the party by letter (1) of the procedures necessary to perfect the appeal and (2) that the date of receipt of the communication will be preserved as the date of filing of the appeal if that party files a fully conforming petition for review within 30 days of the date of the Prothonotary's letter. If the party fails to file a fully conforming petition for review within that period, the Prothonotary shall advise the party by letter that the Court will take no further action in the matter.
