A group that opposes a natural gas pipeline to extend service to Vermont’s Addison and Rutland counties protested Tuesday morning outside Vermont Gas headquarters in South Burlington. Members of Rising Tide Vermont said the pipeline will increase reliance on fossil fuels responsible for climate change. One woman chained herself to the front door. Vermont Gas said a female worker suffered an arm injury as protesters pushed her out of the way. Steve Wark of Vermont Gas told WCAX-TV that the group is out of step with the majority of Vermont residents, who really want natural gas. Police issued trespass notices to the protesters.
