Pipeline Project Scheduled For September In Glastonbury

GLASTONBURY, CT — Algonquin Gas Transmission, LLC this week said it will be conducting an "investigative project" in the Raymond Road area of Glastonbury.

The work is slated to begin on Sept. 18.

This project is officially on the books as, "Mainline System Anomaly Investigation Project, Milepost 1.25, Dig 5696."

The Raymond Road project is one of two projects Algonquin Gas Transmission, LLC will be conducting in Glastonbury during the month of September (Click here to read about the work being done on Thompson Street).

The following project description was provided in a recent letter submitted to local inland wetlands officials:

"As identified in the enclosed mapping, Algonquin is proposing an anomaly investigation project located in the Town of Glastonbury, which will be applied to Algonquin’s existing Mainline pipeline system. The proposed project will take place entirely within the existing Algonquin maintained ROW. Access to the workspace and staging area will come from Raymond Road and proceed east through the existing ROW to the anomaly investigation site. To minimize temporary impacts, appropriate erosion and sediment controls will be utilized to prevent sedimentation into wetlands. To investigate the anomaly, a medium-sized excavator will dig a trench to a depth of approximately 5-10 feet to expose the pipeline. The excavated material will be stockpiled within the temporary workspace located in Algonquin’s ROW. Following excavation, the pipe will be sandblasted to bare metal and the pipe surface will be visually inspected for evidence of corrosion defects. Depending on the severity of the corrosion identified during pipe inspection, remedial measures may include pipe recoating, installing a reinforcement sleeve or replacing a section of pipe. The repair will not require realignment or change in depth of the existing pipe."

Once the work is completed, workers will backfill the trench with the excavated material and restore the areas to original conditions in accordance with the company Erosion and Sedimentation Control Plan, officials said.

Algonquin officials said theprocess of excavation, investigation and remediation typically requires two weeks to complete depending on the site conditions and weather.
