Summary
Waste Management presented a plan to expand Pine Tree Acres landfill by roughly 240 acres to extend capacity about 25 years; staff placed a resolution on the consent agenda and council approved consent items without separate roll call.
Waste Management (WM) representatives and city public‑works staff briefed the Sterling Heights City Council on a proposed expansion of Pine Tree Acres landfill as part of a county solid‑waste plan amendment.
Mike Moore, the city's Department of Public Works director, introduced WM Area Public Works Manager Katie Gordon, who described Pine Tree Acres as the only municipal solid‑waste landfill in Macomb County and said the existing footprint has an estimated five to seven years of remaining disposal capacity at current volumes. Gordon said the proposal adds about 240 acres of WM‑owned property adjacent to the existing site, with roughly 140 acres proposed to be lined and used for disposal; WM estimated the expansion would provide about 25 years of capacity at current tonnage levels.
Gordon addressed community concerns that have surfaced in other jurisdictions, including whether Pine Tree Acres accepts Canadian waste. She stated on the record that Pine Tree Acres accepts Canadian waste and that, by her estimate, about 68% of a particular tonnage breakdown she referenced was Canadian in origin. She also highlighted benefits WM says come with an established facility: opportunities for landfill gas capture and renewable energy generation (WM said existing gas‑to‑energy facilities at Pine Tree support enough generation to power an estimated 19,000 homes) and potential siting of transfer or recycling facilities.
Council members asked about traffic and long‑term plans. Gordon said there is no definitive plan beyond the roughly 25‑year extension; when the site eventually closes WM has experience capping landfills and can maintain gas extraction for decades afterward. City staff noted the issue had been presented to the Sustainability Commission the prior week and that the item was included as part of the consent agenda for council action that evening.
Outcome: the resolution related to Pine Tree Acres was placed on the consent agenda and adopted as part of council's consent‑agenda vote.
Notes and context: the landfill is regulated by the Michigan Department of Environment, Great Lakes and Energy (EGLE) and the proposal was described as an amendment to Macomb County's solid waste management plan. WM characterized the expansion as more efficient than siting a new landfill and noted potential transfer‑station alternatives would come with large capital costs.
