The attorneys representing the Massachusetts Department of Environmental Protection, Algonquin Gas Transmission and a group of residents presented final arguments in a department adjudicatory proceeding over the waterways license of the company’s natural gas compressor station in Weymouth.

In a blow to local environmental justice groups, the D.C. Circuit Court of Appeals dismissed challenges to FERC's authorization of the Weymouth Compressor Station.

FERC’s Republican minority is arguing that the commission’s recent decision on the Weymouth Compressor Station is leading to uncertainty for gas developers.

FERC said it could not reverse its OK of a controversial compressor station, but Democrats pledged to consider environmental justice in future gas cases.

The site of the Weymouth natural gas compressor station previously hosted both a coal facility and a fuel storage tank. 

Enbridge says using a gas-fired turbine for the Weymouth Compressor station is more cost-effective than an electric motor, but stakeholders disagree.
