Brookhaven Seeks Landfill Extension Despite Toxic Plume, Community Anger

The Town of Brookhaven is asking state regulators to keep its 52-year-old landfill running until 2031, a request that has ignited protests at Town Hall and deepened mistrust over a 4-mile-long toxic plume that residents say officials have repeatedly sidestepped.

The New York State Department of Environmental Conservation said it is "actively reviewing" Brookhaven's extension application, which the town submitted on March 1, 2024. The requested five-year permit, if approved, would expire in 2031. The landfill's current operating permit expires July 11, though the DEC has not publicly confirmed the year attached to that deadline. Solid-waste experts say the agency is almost certain to grant the extension, pointing to DEC's history of approving a series of five-year renewals to keep the Brookhaven hamlet facility operating.

The landfill, opened in March 1974, sits at the center of a widening conflict between the town's financial interests and growing environmental pressure. It generates tens of millions of dollars in annual revenue that helps Brookhaven defray solid-waste disposal costs, taking in primarily ash from Long Island incinerators operated by New Jersey-based Reworld, along with construction and demolition debris in Cell 6, the facility's only active cell. The dump now consists of six compacted cells in total: four that previously accepted municipal solid waste were permanently closed after the Long Island Landfill Law halted MSW disposal in 1990, and Cell 5, which accepted C&D debris and ash, was recently capped and closed.

Town officials have announced four successive closure target dates, forecasting shutdown in 2024, then 2025, then 2027, and then 2028. Officials attributed the earlier slippage to COVID-19, arguing the pandemic cut the volume of construction and demolition waste entering the dump. The repeated postponements have sown distrust among residents, environmentalists, and solid-waste experts alike.

The environmental controversy has sharpened around the plume. DEC finalized and accepted the Plume Characterization Investigation Report in July 2025, a key step in the agency's Corrective Measures Assessment Program. But a public meeting to discuss corrective measures has not been scheduled. In December 2025, the town asked DEC to postpone that meeting and also requested the agency consider a legal filing, identified in DEC records as a "Summons with Notice," Index No. 627985/2025, filed with the Suffolk County Clerk on October 17, 2025. DEC granted the town an extension to the Corrective Measures Assessment deadline on January 8, 2026, and as of that date the town had still not finalized a meeting date. In February 2026, DEC responded to a separate town request asking whether the municipal exemption under Environmental Conservation Law Section 27-1323(2) applies to the Brookhaven Landfill, though the substance of that determination has not been made public.

Demonstrators gathered outside Brookhaven Town Hall last month to protest the postponed plume meeting, a visible sign of the frustration that has accumulated over years of delayed closures and unanswered environmental questions. With the permit deadline approaching and the corrective measures process still unresolved, the gap between the town's revenue calculations and its accountability to surrounding communities is becoming harder to ignore.
