In addition to any other remedies provided for in this chapter, 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 chapter or the regulations promulgated under this chapter or any order issued pursuant to this chapter 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 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 these proceedings. In addition to an injunction, the court may levy civil penalties as provided by this chapter.
