FERC: Alternative Trench Protection Measures Can Be Used on Atlantic Bridge Project

Posted on

FERC has approved Enbridge’s request to use alternative trench excavation protection measures on Berkshire Drive and Maple Ridge road in Danbury, Connecticut along the Southeast to Oxford Take-up and Relay Segment of the Atlantic Bridge Project.

According to FERC’s Alisa M. Lykens, Enbridge’s alternative measures include the use of chain-link fence panels to enclose the perimeter of open trench, locate security personnel onsite, and use steel plates to maintain access to landowner driveways.

Once completed, the Atlantic Bridge Project will provide additional capacity on Enbridge’s Algonquin Gas Transmission and Maritimes & Northeast Pipeline systems to transport reliable, economical natural gas into New England and to specific end use markets in the Canadian Maritime provinces.

The project includes:

  • Construction of approximately 6.3 miles of 42-inch diameter mainline take-up and relay pipeline within Algonquin’s existing footprint in New York and Connecticut
  • Construction of a new compressor station with 7,700 horsepower in Weymouth, Massachusetts
  • Addition of two new compressor units, for a total of 14,000 additional horsepower, at two existing compressor stations in Connecticut
  • Replacement of two existing compressor units, for a total of 1,500 additional horsepower, at an existing compressor station in Connecticut
  • Uprate capacity in one compressor unit, for a total of 3,300 additional horsepower, at an existing compressor station in New York
  • Construction of a new meter station in Connecticut and modifications to existing meter stations in New York, Connecticut, Massachusetts and Maine

The project is expected to be in service in November 2017.
