Algonquin Natural Gas Compressor Station, Weymouth

Algonquin Gas Transmission LLC, a subsidiary of Spectra Energy Corp., is proposing to build and operate a natural gas compressor station in the Fore River area of Weymouth.

Air Quality Plan Approval

On January 11, 2019, MassDEP issued a Non-Major Comprehensive Air Quality Plan Approval to Algonquin Gas Transmission LLC, a subsidiary of Spectra Energy Corp., for construction and operation of its proposed natural gas compressor station in the Foe River Area of Weymouth. This facility would support capacity upgrades to, and expansion of, Algonquin’s natural gas transmission pipeline system.

The agency's review of Algonquin's Air Quality Plan Application was limited to air pollution control issues only and its approval does not relieve the company of complying with any other regulatory requirements.

In July 2017, Governor Baker directed MassDEP and the Department of Public Health (DPH) to perform a comprehensive health impact assessment of the Fore River area before MassDEP issued any air permits for the proposed compressor station.

MassDEP had issued a proposed Air Quality Plan Approval for the project in March 2017, and in response to a petition and public interest, held a public comment period which concluded in May 2017.
