Federal Court Nullifies New Jersey Approval for $1B Gas Pipeline to New York City

The project, targeting Q4 2027 completion, aims to add 400,000 dekatherms/day capacity. Williams plans to address the court's concerns, while environmental groups praise the decision. The court noted unresolved compliance measures and technical issues in the state's certification.
