1 Pa. Code § 35.106
The order or notice initiating a hearing for a purpose other than rulemaking will set forth the authority and jurisdiction under which the hearing is to be held, will state the nature of the proceeding, and will specify the final date for the filing of protests to the authorization sought and for the filing of petitions and notices to intervene except in cases where such date has been fixed by a former notice. The order or notice initiating the hearing will not specify the date of hearing unless the agency deems it appropriate that it do so.
