Even though it's been approved by the Public Service Board, protestors want it stopped.
The project's approval means Vermont Gas can start building a pipeline to bring natural gas to Addison County.
But opponents worry about the health and environmental impacts.
"Today we're here again to stand united to bring together workers rights groups and environmental groups to say that we're going to stand united and that people are going to be taking a pledge of resistance. Which would say that if necessary the pledge to take civil disobedience in order to stop this pipeline."
Vermont Gas says the new pipeline will bring a cheaper, more environmentally-friendly fuel source to areas that currently don't have natural gas.
