A subsidiary of Berkshire Hathaway, in partnership with TC Energy, is facing significant public resistance to its proposed Iroquois gas pipeline expansion in Brookfield, Connecticut. On October 14, 2025, it was reported that Connecticut's Department of Energy and Environmental Protection (DEEP) received over 190 comments, all opposing the project's permits. The proposed expansion of a compressor station has raised concerns among residents and local groups due to its proximity to a middle school and the potential for increased pollution in an area already facing ozone challenges. The Brookfield Board of Selectmen and other coalitions have formally petitioned for a public hearing on the matter. The strong community opposition could create regulatory hurdles for the project's approval.
