WM employs state-of-the-art odor control measures for the industry at the landfill, including more recent measures implemented and described in this update. We remain vigilant in our evaluation and implementation of best management practices and technology to enhance operations. WM continues its commitment to the Department and the community by continuing to conduct continuous ambient monitoring for hydrogen sulfide (H2S) at the South and North Monitoring Station and the Dudley/Northside School. The gas collection/control systems also continue to operate at high levels of efficiency this quarter. The data supports that landfill gas is being collected and not migrating off-site and that there is no indication that emissions pose any health concerns. The site’s gas collection and control system, operating records, odor control programs, off-site H2S monitoring data, enhanced quarterly surface scans, DEC notification hotline and follow-up data from a trained odor detection investigator, and DEC inspection reports, all indicate the landfill is operating in a manner that minimizes off-site odors to the greatest extent practicable.
High Acres Landfill & Recycling Center Construction & Operational Update
2nd Quarter 2026
Site Information
The High Acres Landfill began in 1971 and joined WM in 1972. The facility provides environmentally responsible solid waste management to the region. Located on approximately 1,500 acres, the facility offers many amenities. The permitted landfill consists of around 320 acres.
This update provides key enhancements that occurred on-site through the 2nd quarter of 2026. Going forward, WM will provide similar updates on a quarterly basis. Key aspects include community benefits, site construction and monitoring, environmental performance and compliance.

Community
Fairport Canal Days
WM is a proud supporter of the 2026 Fairport Canal Days. High Acres Landfill donates dumpster and garbage services for this amazing community event.
Reminder: The Residential Drop-Off Facility is intended to replace your at-home waste/recycling needs only. NOT FOR COMMERCIAL USE.
Site Construction Activities
Cell 14A (8.9 Acres)
Currently preparing the subgrade in Cell 14A. We will employ all necessary odor control measures. Our contractors understand that keeping odors to a minimum is a top priority, and we will provide appropriate oversight on construction activities.
(RNG) Renewable Natural Gas Facility
This nearly complete, state-of-the-art renewable natural gas (RNG) facility in Macedon will uses landfill gas that is generated when organic material decomposes in a landfill. It will reduce the current combustion of landfill gases on-site by converting LFG to RNG, which is pipeline-quality gas, thus reducing emissions. Existing on-site flares will continue to handle excess gas generation and act as redundant control combustion capacity. According to the USEPA, “Use of RNG can provide benefits in terms of fuel security, economic revenues or savings, local air quality, and greenhouse gas emission reductions.”
(RNG) Renewable Natural Gas Facility
The facility will process up to 8,000 scfm of landfill gas, which is equivalent to 2 million MMBtu of RNG delivered to the pipeline. (Serves the needs of approx. 30,000 households) The facility will provide a local greenhouse gas reduction equivalent to removing 21,000 cars from the road per year. (100,000 MT CO2e/year avoided emissions). This facility is scheduled to be commissioned in Q3 2026. The current landfill gas-to-electricity plant will then go offline after several decades of successfully managing landfill gas.
