58 Pa. C.S. § 3257
Nothing in this chapter stops the Commonwealth or a district attorney from proceeding in a court of law or in equity to abate pollution forbidden under this chapter or a nuisance under existing law. It is hereby declared to be the purpose of this chapter to provide additional and cumulative remedies to control activities related to drilling for, or production of, oil and gas in this Commonwealth, and nothing contained in this chapter abridges or alters rights of action or remedies existing, or which existed previously, in equity or under common or statutory law, criminal or civil. Neither this chapter, the grant of a permit under this chapter nor an act done by virtue of this chapter stops the Commonwealth, in exercising rights under common or decisional law or in equity, from suppressing a nuisance, abating pollution or enforcing common law or statutory rights. No court of this Commonwealth with jurisdiction to abate public or private nuisances shall be deprived of jurisdiction in an action to abate a private or public nuisance instituted by any person on grounds that the nuisance constitutes air or water pollution.
