Proposal for the “Algonquin” Gas Transmission (AGT) pipeline, a division of Enbridge
AGT’s PROJECT MAPLE PROPOSAL
• OPEN SEASON FOR BIDS Ended November 17th, 2023
Enbridge sought bids from buyers for increased capacity on its “Algonquin” Gas Transmission (AGT) pipeline. The proposed “Project Maple” plan would have supplied an increase of up to 750,000 dekatherms a day (Dth/d), depending on customer need. It was proposed as an expansion of the existing AGT pipeline system, most likely to be along the G and J laterals.
Open Season closed in November 2023. This project has not been filed with FERC.
OTHER AGT PROJECTS COMPLETED
Other projects were filed, approved and completed concurrently with Project Maple proposal time.
Since the end of the bidding season for Project Maple, Enbridge filed two projects with FERC, adding capacity on lateral lines of the main Algonquin Gas Transmission (AGT) line, the same G and J Laterals that were the focus of Maple. We believe these are a means to getting small portions of what was technically “Project Maple” approved more easily. This practice has been ruled in court cases on other projects as “impermissible segmentation”.
Both of these projects were filed with FERC, and asked for “blanket authority” under an existing permit from 1987. Filing this way, these projects would have received automatic approval if no protests were filed in response. Opposing organizations were able to get protests filed on both dockets in time to trigger review by FERC, but they were subsequently approved by FERC and have been constructed.
Other projects completed:
– Coventry CT Regulator – FERC docket #CP24-21: a regulator facility added to an injection site on the E-1 lateral in Coventry, CT
– Sakonnet River Replacement – FERC docket #CP24-49: replacement of existing 6″ pipeline with a 12″ pipeline under the Sakonnet River in RI (part of Narragansett Bay). Like many of Enbridge’s projects, this one experienced “frac out”, and accidental leak of drilling mud at a Horizontal Directional Drilling (HDD) site.
*Both of these increased capacity on the existing AGT system.
– Lincoln Meter Station upgrade. This project was small enough to not require filing with FERC or state agencies. It was a re-bolstering of an existing meter station at Lincoln, MA, replacing its rotting wooden foundation and protecting it with further weatherization enclosure. Cutting of trees for temporary work space in the buffer zone of the local aquifer prompted tree-sitting protests. Some trees were saved, others not.
