3 Pa. Stat. § 111.51
In addition to any other remedies provided for in this act, the Attorney General, at the request of the secretary, may initiate in the Commonwealth Court or the court of common pleas of the county in which the defendant resides or has his place of business, an action in equity for an injunction to restrain any and all violations of this act or the rules and regulations promulgated hereunder or any order issued pursuant to this act from which no timely appeal has been taken or which has been sustained on appeal. In any such proceeding, the court shall, upon motion of the Commonwealth, issue a preliminary injunction if it finds that the defendant is engaging in unlawful conduct, as defined in section 28 of this act, or is engaging in conduct which is causing immediate or irreparable harm to the public. The Commonwealth shall not be required to furnish bond or other security in connection with such proceedings. In addition to an injunction, the court, in such equity proceedings, may levy civil penalties as provided insection 30 of this act.
