Debate Grows Over Expansion of New York’s Largest Landfill

A major environmental fight is unfolding in New York over the future of the Seneca Meadows Landfill in Seneca Falls — the largest landfill in the state.

The landfill, originally expected to close in 2025, is now seeking state approval to remain open and expand operations through 2040. For environmental advocates, the proposal is about far more than one community. They argue it is a test of whether New York will continue relying on mega-landfills or move toward a different model of waste management.

To discuss the issue, Radio Catskill’s Patricio Robayo spoke with Yvonne Taylor, vice president of Seneca Lake Guardian.

Taylor described Seneca Meadows as a massive facility that already takes in about 6,000 tons of waste a day from 47 counties in New York, along with trash from other states and Canada. If approved, she said, the landfill would grow another seven stories higher and expand by 47 acres — becoming even more dominant over the surrounding landscape.

“This is already an enormous mountain of garbage,” Taylor said. “The proposal would make it even bigger, even taller, and keep it operating for another 15 years.”

For people living nearby, Taylor said the impacts are immediate and constant. Residents have long complained about overpowering odors, and she said schools located within a few miles of the landfill are sometimes forced to deal with the smell both outside and inside classrooms. She said families, teachers and students have reported headaches, nausea and difficulty concentrating.

But Taylor said the concerns do not stop at Seneca Falls.

She pointed to the landfill’s production of leachate — contaminated liquid created when rainwater filters through garbage. That leachate can contain PFAS, often called “forever chemicals,” along with other pollutants. According to Taylor, millions of gallons are shipped to wastewater treatment plants around New York, even though those facilities are not designed to remove many of those contaminants.

“This waste doesn’t just stay in one place,” Taylor said. “It moves through communities and into waterways across the state.”

She also argued the landfill’s methane emissions make it a broader climate issue. Methane is a potent greenhouse gas, and Taylor said large landfills like Seneca Meadows undermine New York’s climate goals while prolonging dependence on a throwaway waste system.

The proposed expansion is now being reviewed by the New York State Department of Environmental Conservation through the state environmental review process. Taylor said the agency has sent the application back for more information multiple times, but a final public comment period has still not yet begun.

When it does, advocates expect the fight to intensify.

Taylor said opponents want the landfill to close when it reaches capacity, not be allowed to expand again. She argues New York already has the framework for a different path, pointing to the state’s solid waste management plan, which calls for stronger recycling, waste diversion and a move toward a more circular economy.

“This is really a question about what kind of future New York wants,” Taylor said. “Do we keep expanding mega-landfills, or do we finally start reducing the waste stream and building a better system?”
