Activists are pushing against a pipeline project by Columbia Gas running from Holyoke to Agawam.
The Northampton City Council voted to oppose the project at its meeting on Thursday, while those in attendance criticized Columbia for the gas-fueled explosions that occurred in northeastern Mass last month.
Protesters also marched to Holyoke yesterday to deliver a letter to Holyoke Gas and Electric and city officials.
The addition to the pipeline would include a two mile loop from Agawam to Holyoke.
Some residents say they are scared after the explosions in Andover and in Lawrence.
