Seneca Meadows is New York State's largest active landfill. Considered a mega-landfill, Seneca Meadows occupies over 350 acres and is located in the Towns of Seneca Falls and Waterloo on a portion of the approximately 2,400 acres of land privately owned by Seneca Meadows, Inc., a subsidiary of Texas-based Waste Connections. Seneca Meadows stands almost 300 feet tall, making it one of the tallest man-made structures in Upstate New York.

Seneca Meadows is owned and operated by Waste Connections, Inc., a private waste management company located in Texas. It operates under permits issued by the New York State Department of Environmental Conservation (NYSDEC).

Seneca Meadows accepts waste from across the state, neighboring states like Massachusetts, Pennsylvania, New Hampshire, Vermont, Rhode Island and Connecticut, and has even accepted waste from Canada; while nearly three-quarters of its waste comes from New York City, Long Island, and lower Hudson Valley suburbs.

This has raised concerns about upstate communities shouldering the burden of downstate and out-of-state waste.

Currently, Seneca Meadows rises to approximately 280 feet above grade in some areas. If the Valley Infill Expansion is approved, the landfill could reach over 300 feet, making it a dominant visual feature in the flat Finger Lakes landscape.

Yes. Seneca Meadows operates a landfill gas recovery system that captures methane and transmits it to a facility that converts it into electricity and renewable natural gas (RNG). While this is promoted as a sustainability initiative, some experts caution that landfills can still release significant amounts of fugitive (uncontrolled) emissions. These experts argue that capturing a portion of these emissions does not offset the broader environmental harm caused by landfilling and may even slow progress toward more meaningful waste reduction solutions by incentivizing the continued disposal of large amounts of waste in landfills.

The first documented waste disposal on the Seneca Meadows property began in 1958, and  includes the Tantalo Waste Disposal Area, which  is an approximately 26-acre area originally listed by the NYSDEC as a Class 2 Inactive Hazardous Waste Disposal Site, as it received various municipal and industrial waste streams from 1958 until 1972.

Seneca Meadows assumed control of the landfill in 1983 and has operated the Facility since that time under a series of NYSDEC permit renewals and modifications, as detailed below.

Seneca Meadows takes in up to 6,000 tons of waste per day, totaling around 2 million tons per year.

This is the name given to the proposed expansion of the Seneca Meadows facility. The project intends to add approximately 15 years to the landfill's lifespan by increasing its vertical height and creating new disposal areas within a valley, specifically over a listed inactive hazardous waste disposal site.

The Valley Infill Expansion would:

This proposal is currently under environmental review by NYSDEC, and it faces heavy public and legal opposition.

NYSDEC is the lead agency reviewing the potential environmental impacts of Seneca Meadows' proposed expansion under the State Environmental Quality Review Act. NYSDEC is responsible for determining whether the expansion has unavoidable environmental impacts.

No. As of now, the expansion has not been approved. Seneca Meadows has submitted a proposal to expand operations through 2040, but it must undergo a State Environmental Quality Review and public review process. Approval would require NYSDEC permits and would likely be subject to legal challenges.

Yes. The expansion process requires environmental review, including a Draft Environmental Impact Statement and public comment period. Local residents, environmental groups, and elected officials are encouraged to submit comments and attend hearings to voice concerns.

Residents living near the Seneca Meadows Landfill are primarily concerned about potential health risks, environmental contamination, and quality of life issues related to the landfill's operation. Specifically, they are worried about odors, increased truck traffic, potential groundwater contamination, and the release of landfill gases like methane and hydrogen sulfide. Some residents also express concerns about the possible impact of the landfill on local lung cancer rates and other health issues. Residents are also concerned about the landfill's proposed expansion and the potential for increased environmental and health risks associated with it. Opponents believe the landfill detracts from the Finger Lakes region's potential for tourism and quality of life.

Despite modern design standards, landfills remain a threat to environmental and public health:

The landfill emits gases like methane, carbon dioxide, hydrogen sulfide, and volatile organic compounds as well as hazardous air pollutants. While gas collection systems are in place, not all emissions are captured. Residents have reported:

Leachate is a toxic liquid created when water passes through buried waste. At Seneca Meadows, some leachate is treated on-site via a reverse osmosis process and then sent to the Seneca Falls Wastewater Treatment Plant for further treatment and discharge into the Cayuga-Seneca Canal. A significant portion of the leachate is also transported to other sewage treatment plants in Buffalo, Watertown and Amsterdam for treatment before being discharged to other important waters of the state. Critics argue this merely shifts pollution to other municipalities that may not be equipped to handle industrial-strength leachate, particularly regarding the removal of PFAS chemicals.

Common hazardous materials found in landfills include:

These substances can leach into soil and water, affecting nearby ecosystems and human health. In addition, landfills such as Seneca Meadows can accept industrial wastes, incinerator ash, sludge, and contaminated soil, which harbor hazardous constituents.

PFAS (per- and polyfluoroalkyl substances) are synthetic “forever chemicals” found in products like non-stick cookware, food wrappers, and industrial waste. They don’t break down and can contaminate water. PFAS has been found in leachate from many landfills, including those in New York. While treatment systems may remove some PFAS, many facilities receiving landfill leachate are not equipped to fully eliminate them.

Thousands of trucks bring waste to Seneca Meadows each month. This results in:

Many trucks come from long distances, highlighting the regional waste burden being concentrated in one community.

A landfill is a site where waste is buried or piled. While engineered to contain trash, landfills are still a major source of pollution, greenhouse gas emissions, and environmental injustice. In New York State, landfills continue to affect local ecosystems, air and water quality, and nearby communities.

A mega-landfill is a very large disposal site for waste, often handling a disproportionate amount of trash, including waste imported from distant cities and states, making them a focal point for regional waste management. They are distinguished by their large size and the enormous volume of waste they process, sometimes exceeding 5,000 tons daily. Some notable examples include the Frank R. Bowerman Landfill in California and the Seneca Meadows landfill in New York, both of which are known for their enormous size and the amount of waste they accept and manage.

Mega-landfills can generate significant pollutants, as well as odors, primarily from hydrogen sulfide and ammonia, impacting the quality of life for nearby residents. The massive size of these facilities necessitates large land areas, often leading to habitat destruction and potential biodiversity loss. Because mega-landfills often serve extensive regions, waste needs to travel longer distances, resulting in increased greenhouse gas emissions from transportation as well as landfill off-gassing.

Yes. Environmental justice communities—often low-income and less-populated neighborhoods—are disproportionately impacted by waste infrastructure, including landfills. These communities face higher health risks and fewer opportunities to shape local environmental decisions. Seneca Falls and Waterloo have been designated “Economically Disadvantaged Communities” by NYSDEC under the CLCPA. Our organization, CCSC, works to amplify their voices and demand equity in waste planning.

The Finger Lakes is known for clean water, agriculture, and tourism. Many residents and advocates argue that hosting the state’s largest landfill is incompatible with the region’s environmental values, public image, and economic future.

Many cities, towns, villages, and organizations in the Finger Lakes have formally opposed the landfill’s continued operation and expansion. They argue it is inconsistent with the region’s identity as a hub for eco-tourism, clean agriculture, and wine production.

Yes, reputationally, so say the wineries, themselves. The Finger Lakes is home to award-winning wineries and organic farms, many of which rely on clean air, healthy soil, and uncontaminated water. Odors, truck traffic, and potential water and air pollution all threaten this identity—and some businesses report tourist complaints linked to the landfill’s presence.

To quote Doug Hazlitt, co-owner of Hazlitt 1852 Vineyards, and member of a seventh generation farm and wine producing family in the Finger Lakes:

“The landfill is a massive threat to our economy. Farms and tourism, the backbone of our heritage that some have spent generations building, risk losing their appeal if the perception of Seneca County — and by extension, the region — shifts from one of natural beauty to one associated with waste disposal. The landfill, if expanded, will affect our property values and future investments in the region. . . .”

Seneca Meadows is a regional and statewide issue:

The New York State Department of Environmental Conservation regulates landfill siting, construction, operation, and closure under 6 NYCRR Part 360 regulations. These regulations are meant to protect communities and the environment—but enforcement and oversight can vary.

DEIS: This stands for Draft Environmental Impact Statement. A DEIS is a document prepared as part of the environmental review process to evaluate the potential environmental effects of a proposed project like the proposed Valley Infill.

Local Law 3, passed by the Town of Seneca Falls in 2016, prohibits solid waste disposal in Seneca Falls, NY after December 31, 2025. The law reflects strong public desire to close the landfill. However, Seneca Meadows is actively seeking to override or bypass this law through permit extensions, expansion proposals, and lawsuits.

As of now, Seneca Meadows is seeking permits to expand and continue operations beyond 2025 despite the town’s 2016 closure law. The matter is unresolved and involves ongoing litigation, regulatory review, and public opposition.

A lawsuit has been filed against Seneca Meadows Landfill and the New York State Department of Environmental Conservation, alleging that the landfill's operations and the DEC's regulatory oversight violate New York's 2021 Green Amendment, which guarantees the right to clean air, water and a healthful environment. The lawsuit specifically focuses on the landfill's emissions, including noxious odors, and seeks to prevent the landfill's expansion.

The state Attorney General has argued that the Green Amendment does not alter the DEC's enforcement discretion, suggesting that the agency can still choose how to regulate the landfill.

The Seneca Meadows case is one of several lawsuits testing the interpretation and application of the Green Amendment in New York, particularly concerning the role of the DEC in regulating landfills.

Hundreds of entities have voiced opposition to the proposed expansion of the Seneca Meadows landfill, including regional governments, environmental groups, and over 500 local businesses. Specifically, the Schuyler and Tompkins County legislatures, the Town and City of Geneva, the Town and Village of Skaneateles, the Town of Ulysses, the Villages of Interlaken and Watkins Glen, and the city of Rochester have all expressed opposition. Additionally, the Haudenosaunee Confederacy—representing the Cayuga, Seneca, Onondaga, Mohawk, Oneida, and Tuscarora indigenous nations—has also joined the opposition.

To eliminate imported waste as a central feature of our economy, thus safeguarding our neighborhoods from related environmental and health hazards.

Residents and advocates can:

Public input can make a real difference in environmental review outcomes.

Advocates want to see:

If you are experiencing odors from the Seneca Meadows Landfill, there are several ways to file a complaint and ensure your concerns are heard:

Important Notes:

Yes. Residents have reported numerous and persistent air quality complaints and foul smells, particularly during warmer months, but no records can be located at present regarding whether Seneca Meadows has received notices from NYSDEC for odor violations, stormwater concerns, and operational issues.

If the 2025 closure date holds, the landfill would:

Closure would also end the annual host payments to the town, requiring a shift in local budgeting.

New York City and other regions could:

Keeping landfills like Seneca Meadows open is often the cheapest short-term option, but it may be the most harmful long-term.

Even after closure, Seneca Meadows will need active monitoring and maintenance for decades. Closed landfills can:

Post-closure care is required by law for at least 30 years, but some impacts may last far longer.  The EPA estimated that the duration of the hazard from a landfill would be "many thousands of years."

New York State can:

Examples include:

Seneca Meadows provides local host payments to the Town of Seneca Falls—millions of dollars annually—which are used to offset taxes and fund town operations. However, opponents argue these short-term financial gains are outweighed by:

The Town of Seneca Falls entered into a host community agreement with Seneca Meadows, allowing the landfill to operate through 2025 in exchange for annual payments. However, the town passed Local Law No. 3 in 2016 to prohibit waste disposal in Seneca Falls after2025—a move that has led to legal and political conflict.
