Local and regional decisions about waste management continue to evolve rapidly, with implications for environmental compliance, public accountability, and long-term planning.
Solid Waste Management & Coffin Butte Landfill
Following the filing of a Notice of Intent to Appeal with the Land Use Board of Appeals (LUBA) by Benton County residents, the Benton County Board of Commissioners took procedural action to withdraw its prior approval of the Coffin Butte Landfill expansion. At the December 16, 2025, Board meeting, Commissioner Nancy Wyse moved to withdraw the decision for reconsideration, and County Appointed Counsel subsequently filed a formal notice of withdrawal with LUBA.
On January 20, 2026, the public record for Land Use Case LU-24-027 was reopened to admit a November 6, 2025, Oregon Department of Environmental Quality (DEQ) pre-enforcement notice. That notice, issued two days after the Board’s original approval, identified significant compliance concerns related to landfill gas emissions.
On January 26, 2026, the League of Women Voters of Corvallis submitted testimony to the Benton County Board of Commissioners during the Coffin Butte Landfill Reconsideration Hearing. The testimony requested a denial of the Conditional Use Permit to expand the landfill. The testimony is part of the public record (BOC4_T0746, January 25, 2026).
The Reconsideration Hearing and Board deliberations have been continued to the March 3, 2026, regular Board of Commissioners meeting. Adoption of findings is tentatively scheduled for March 17, 2026.

Joint Task Force on Municipal Solid Waste in the Willamette Valley
The Joint Task Force on Municipal Solid Waste in the Willamette Valley, established under House Bill 3794, held its first organizational meeting on December 16, 2025. That meeting provided an overview of the legislation and reviewed the regional Sustainable Materials Management Plan developed through the 2025 Benton County–funded SMMP Task Force.
The second Task Force meeting, held January 30, 2026, was largely informational and included presentations from the Oregon Department of Environmental Quality. Benton County Solid Waste Coordinator Bailey Payne presented research on transfer station models in Oregon and the Pacific Northwest, illustrating options that could be considered in Benton County following the eventual closure of the Coffin Butte Landfill.
Representative Sarah Finger McDonald, sponsor of HB 3794 and a Task Force member, asked detailed questions regarding facility costs and potential impacts on garbage rates. A Task Force member from Marion County Environmental Services described Marion County’s recovery systems and shared a comparative financial context.
According to DEQ’s 2022 Oregon Material Recovery and Waste Generation Rates Report, Lane County has the highest recovery rate among Oregon county-defined waste sheds at 52.9%, followed by Marion County at 46.7%. Linn County ranks third at 44.3%, while Benton County ranks eighth at 31.5%. Marion County is the largest contributor of waste to the Coffin Butte Landfill (just over 20%), followed by Linn County at approximately 16%.
The next Task Force meeting, scheduled for March 2026, will feature a presentation from Lane County on its county-owned landfill, recovery operations, and long-term sustainable materials management planning.
These proceedings raise important questions about environmental oversight, public process, and long-term planning for waste management in our region.
