The land conservation community was stunned five years ago when the private, for-profit PennEast pipeline company announced plans to build a gas pipeline from Luzerne County, Pa. across the Delaware River to New Jersey, cutting through thousands of acres of preserved open space and farmland.

Many locals, including those of us at the New Jersey Conservation Foundation, were shocked that they would seek to cut across so much preserved land.

In January 2018, over objections from landowners, PennEast obtained conditional approval from the U.S. Federal Energy Regulatory Commission to build the pipeline. PennEast had sued in federal district court to use the federal government’s eminent domain power to condemn the 131 properties along the route in New Jersey under the U.S. Natural Gas Act, which was granted in December of last year.

But they won’t able to move forward thanks to an appeal of that decision by the State of New Jersey. On Sept. 10, the Third Circuit of the U.S. Court of Appeals overturned the lower court’s decision, ruling that PennEast cannot legally condemn land preserved by the state.

The court found that the state’s “sovereign immunity” under the Eleventh Amendment protects it from federal lawsuits — like condemnations — brought by private companies. The court rejected PennEast’s claim that the Federal Energy Regulatory Commission can delegate its authority to condemn state lands to a private company.

The decision means that the company can no longer use eminent domain to seize 42 properties preserved by the state, many of them in partnership with counties, municipalities and private land trusts.

The ruling is a major victory for New Jersey Attorney General Gurbir Grewal, and for New Jersey taxpayers, who have invested billions of dollars in preserving open space and farmland for future generations. The ruling has implications beyond New Jersey, as it applies to all state-preserved lands where the state is not a willing partner in condemnation proceedings.

While the decision reduces the chance that the PennEast pipeline will be built, the company has said they are reviewing the decision and their options. An appeal would require petitioning the Third Circuit to reconsider, or petitioning the U.S. Supreme Court.

Forty-two of the 131 properties targeted for condemnation — nearly a third — are state-preserved farmland and open space. They include special places like the Ted Stiles Preserve at Baldpate Mountain, the Milford Bluffs, the Wickecheoke Creek Greenway, and some of the state’s first preserved farms in the Rosemont Valley.

Many New Jersey officials and landowners were struck throughout the process by how much of the pipeline route would cut through preserved lands.

But the new court decision puts an end — at least for now — to the company’s right to access and take state-preserved properties. It also leaves the company’s permit application with the New Jersey Department of Environmental Protection in limbo.

It’s been five years since the project was announced. Since then, many studies have shown that the pipeline is not needed and would have severe impacts to water, land, and communities.

It’s now time for the companies behind PennEast to scrap the pipeline project. Gas experts have clearly demonstrated that the PennEast pipeline is not needed. New Jersey has more than enough pipeline capacity even during periods of peak demand, and the project has no proven public benefit.

For more than 60 years, voters in the nation’s most densely populated state have supported open space and farmland preservation, voting to spend billions of dollars to acquire land that grows our food, safeguards our water supplies, protects wildlife, and provides public recreation.

These precious preserved lands should never be sacrificed for a private company’s profit-making endeavor.
