Energy and environmental lawyers across the state said a recent ruling by the U.S. Court of Appeals for the Second Circuit allowing the construction of a 39-mile long, 30-inch wide natural gas pipeline through Northern Pennsylvania to proceed provides some guidance as to the Federal Energy Regulatory Commission’s standard of review.

A number of environmental activist groups had opposed FERC’s order granting Central New York Oil and Gas Co. permission to build the pipeline, known as the MARC I, claiming FERC did not examine closely enough the possible environmental impact of the project.
