Chaffee Landfill
Sardinia / Chaffee
Long-running landfill complex on Olean Road containing closed disposal areas alongside an active permitted operation. Unlike the atlas's completed brownfields, Chaffee remains an operating solid-waste facility; its historic cells, current cells, leachate and gas systems, permits, and proposed expansions must be kept distinct.
The documented story
What happened here?
Chaffee Landfill has accepted waste on Olean Road since 1958, but the facility is not one uniform mound. Its oldest 36-acre disposal area was built before modern liner rules and placed waste directly on native clay and glacial till. A later 15-acre addition used a two-foot clay liner and leachate collection, and subsequent Western and Valley Fill expansions added separately engineered capacity.
That sequence matters because every era has a different environmental defense. The unlined original area depends heavily on its perimeter leachate collection and final cover; newer cells add liners and secondary collection; closed grades receive geomembrane-bearing final cover; and landfill gas is collected from the old and newer waste areas for engines or other control devices.
Chaffee remains an active municipal solid-waste facility on a roughly 700-acre property, not a completed brownfield. Its permit allows municipal waste plus approved non-hazardous commercial or industrial material, while air permits govern methane collection, flares, and the renewable-energy engines. Monitoring and annual reports are therefore operating evidence, not postscript.
DEC completed environmental review and issued permit materials for multiple expansions, but the names can mislead. The Western Expansion and Valley Fill appear in current operating records; the separate Southern Expansion proposal described in 2022 and 2023 included a 20-acre lateral cell, additional valley fill, and vertical capacity. WNYAtlas keeps proposed and operating footprints distinct unless a later construction record proves otherwise.
Chronology in context
Turning points in the public record
1958 onward
Waste disposal began in an unlined 36-acre area; the property later passed through CID, Chaffee Landfill, and Waste Management ownership.
1981–1999
State permits added perimeter leachate controls, expanded the permitted footprint to about 51 acres, and increased capacity and placement rates.
Western Expansion era
A separately engineered landfill added about 8.3 million cubic yards of non-hazardous-waste capacity and expanded gas collection and energy recovery.
2022–2023
DEC reviewed the Southern Expansion and issued a five-year Title V permit governing landfill-gas and renewable-energy equipment.
2024 operating record
The annual report documented continuing activity in the Western and Valley Fill areas, with leachate, gas, groundwater, capacity, and closure reporting.

A major expansion proposal enters public permit review
DEC released draft solid-waste and air permits for a proposed 20-acre southern cell, 10 acres of valley fill and vertical expansion, making public comment part of the operating landfill's continuing history.
New York State Department of Environmental Conservation ↗Environmental review closes while a renewed air permit governs active landfill gas
DEC accepted the final supplemental environmental impact statement for the Southern Expansion and issued a Title V permit through 2028. The air permit regulates gas collection and energy equipment; it is not by itself proof that every proposed disposal footprint was constructed.

Documented impacts
- The original 36 acres are unlined; later areas use clay or composite liner systems, so leachate and groundwater results must be read by cell and monitoring location.
- Landfill leachate and methane are expected decomposition products requiring collection, measurement, treatment or disposal, and air-pollution controls.
- The separate legacy hazardous-waste record for CID/Chaffee and its completed vapor review do not turn every modern operating cell into a State Superfund site.
Response
Cleanup and controls
- Liners, leachate collection, daily and intermediate cover, geomembrane-bearing final caps, and stormwater controls limit releases from the applicable cells.
- A network of vertical wells and horizontal collectors sends landfill gas to the renewable-energy facility or approved control equipment.
- Groundwater monitoring, annual reporting, inspections, financial assurance, closure estimates, and post-closure care apply across the appropriate operating and closed units.
Then and now
The site today
Chaffee remains operating waste infrastructure with a 1958 landfill embedded inside it. The page therefore names the unit and date behind each claim: an unlined original area, later lined cells, operating Western and Valley Fill capacity, and a separately reviewed Southern proposal. That is more accurate than calling the entire property either an old dump or a modern lined landfill.
