Vermont Gas pipeline investigation expands

State regulators are investigating whether Vermont Gas Systems buried a pipeline in Addison County as deeply as required by its permit.

The attorney who requested the investigation said the pipeline burial depth was too shallow in numerous locations.

The pipeline’s 2013 permit required it to be buried at least 4 feet deep in a 2,500-foot section near New Haven, but in at least 18 locations along that length, the pipe was not buried that deeply, which Vermont Gas has acknowledged. The pipeline was completed in April.

The pipeline is buried under as little as 3 feet of earth in spots along parts of that stretch, the Department of Public Service has claimed. Department officials have said that the pipe is nevertheless buried deeply enough to be safe.

Vermont Gas representatives have filed a request with the Public Utility Commission (formerly the Public Service Board) asking for a retroactive amendment to the pipeline permit that would treat the burial-depth discrepancy as an insubstantial change from the original permit’s terms.

The commission on Friday opened an investigation into whether the burial-depth discrepancies are insubstantial, as Vermont Gas claims.

If the deviations are found to be non-substantial, Vermont Gas could be required to complete some paperwork to make the permit current. If the deviations are found to be substantial, the commission may impose fines or other penalties, including requiring the pipeline be reburied.

But the attorney who requested this investigation now claims he has evidence that Vermont Gas failed to meet burial depths required in the pipeline’s permit at far more locations than the 18 that the commission is looking into.

Jim Dumont, a Bristol lawyer representing pipeline opponents, filed a second request asking the Public Utility Commission to expand its investigation to include the pipeline’s burial depth beneath waterways and beneath residential areas. Dumont said he and others have found documents that appear to show Vermont Gas didn’t bury the pipe in these areas as deeply as the permit required as well.

The permit requires the pipe to be buried at least 7 feet deep beneath streams, and 4 feet deep in residential areas. Dumont said construction documents show a 5-foot depth between dozens of streams and suggest that the pipe is buried under as little as 3 feet of earth in residential areas.

Vermont Gas spokeswoman Beth Parent repeated the same answer twice when asked if the pipeline was buried deeply enough.

Parent said only that “this pipeline is built safely and adequately, period.”

She added: “We’re proud of the work we’ve done” in providing Addison County residents with the option of buying natural gas.

Federal pipeline regulations generally require the pipe to be buried at least 3 feet underground, and Parent has said before that the pipeline does meet that standard.

Dumont said it was on the town of Monkton’s website where he and his clients found the construction documents that appear to show the burial-depth discrepancies.
