Pipeline Update: Pennsylvania Commonwealth Court Allows Environmental Rights Amendment Challenge to Sunoco Pipeline’s Mariner East Project to Proceed
The Pennsylvania Commonwealth Court recently ruled that a challenge to Sunoco Pipeline L.P.’s (“Sunoco”) Mariner East Project under Article 1, Section 27 of the Pennsylvania Constitution (the “Environmental Rights Amendment” or “ERA”) may proceed. In Clean Air Council, et al. v. Sunoco Pipeline L.P., Docket No. 112 C.D. 2017 (Opinion issued April 30, 2018), the Court reversed, in part, the trial court’s denial of Sunoco’s motion for summary judgment, ordering an entry of summary judgment for Sunoco on all counts except for Plaintiffs’ claims brought under the ERA.
The case involves a challenge by Clean Air Council (“CAC”) and other individuals to Sunoco’s Mariner East Project, a pipeline construction project designed to transport natural gas liquids across Pennsylvania from the Marcellus and Utica basins to Marcus Hook in eastern Pennsylvania. Plaintiffs brought a variety of claims challenging Sunoco’s right and power to condemn property including a challenge to Sunoco’s public utility status as well as various constitutional claims, including an ERA claim, takings claims, and procedural due process claims. Plaintiffs are seeking declaratory and injunctive relief that would halt pipeline construction.
