The state Supreme Court is considering whether Connecticut officials were wrong not to study the potential environmental impacts of a major natural gas expansion plan they approved in 2013.
The court's review comes in a lawsuit filed by an association representing gasoline and heating fuel marketers.
The association alleges state environmental officials and utility regulators violated state law by approving the gas expansion plan without performing an environmental impact evaluation. The group claims the plan will increase greenhouse gas emissions.
The plan calls for expanding natural gas service to 300,000 more homes and building 900 miles of gas mains over the next decade.
A lower court judge dismissed the lawsuit. The association appealed to the Supreme Court, which heard arguments last week.
It's not clear when the court will rule.
