Town of Weymouth v. Massachusetts Department of Environmental Protection, No. 19-1794 (1st Cir. 2020)Annotate this Case
The First Circuit vacated an air permit granted by the Massachusetts Department of Environmental Protection (DEP) for a proposed natural gas compression station set to be built in Weymouth, Massachusetts as part of Algonquin Gas Transmission, LLC's Atlantic Bridge Project, holding that the DEP did not follow its own established procedures for assessing whether an electric motor was the Best Available Control Technology (BACT).
The Atlantic Bridge Project is a natural gas pipeline connecting the Northeastern United States and Canada. The DEP approved Algonquin's non-major comprehensive plan application for the station and granted the station's air permit, certifying its compliance with the Massachusetts Clean Air Act (CAA), Mass. Gen. Laws ch. 111, 142A-142F. Petitioners, nearby municipalities and two citizen-petition groups, argued that DEP violated the CAA and related laws and regulations. The First Circuit (1) vacated the air permit and remanded to DEP for it to conduct further proceedings, holding that the DEP's final decision excluding an electric motor was arbitrary and capricious; and (2) resolved the remaining issues in favor of DEP.
