New York Gov. Andrew Cuomo (D) rejected a permit to build a controversial pipeline that would lock the nations largest city into decades of dependence on fracked gas when scientists say the world needs to rapidly wean off fossil fuels.

The proposal for the Northeast Supply Enhancement Pipeline better known as the Williams Pipeline, after the Oklahoma company behind the project is to lay a new conduit under Lower New York Bay to carry gas from hydraulic fracturing sites in Pennsylvania to homes in Brooklyn, Queens, Staten Island and Long Island. Methane, the primary component in fracked gas, produces potent emissions that, at least in the short term, trap more heat in the atmosphere than carbon dioxide.

Late Friday afternoon, the state Department of Environmental Conservation denied the companys second application for a permit to extend the pipeline from New Jersey via Raritan Bay through the southern portion of New York Bay. In an 18-page letter , Daniel Whitehead, director of the agencys Division of Environmental Permits, cited the apparent lack of need for the Project, as well as its increased impacts to water quality as compared to identified alternatives to reject the proposal with prejudice, meaning the company cannot reapply.

Thats the end of the line, said Suzanne Mattei, a former regional director at the New York State Department of Environmental Conservation, who campaigned against the project. A denial with prejudice means the department has determined the environmental impacts of the pipeline are unacceptable and that the company has not given it reason to believe that it can make changes to its proposal that would convert it into an acceptable proposal.

But the rejection could spur new challenges from the Trump administration, which last year sought to limit the states ability to use the federal Clean Water Act to block projects like the pipeline.
