Seven Oregon Counties Team Up On Garbage
What that means for Benton County and Coffin Butte...
The Coffin Butte landfill expansion issues have been well covered, but now a proposal is being discussed by seven Oregon counties. This is a new development.
The proposal could change how garbage and recycling are managed across much of the Willamette Valley, with Benton County and Coffin Butte finding themselves at the center of the conversation.
County leaders are exploring the idea of creating a new regional authority to oversee long-term solid waste planning. The effort comes as communities across western Oregon face the same problem… landfill space has become increasingly limited.
As Marion County Commissioner Danielle Bethell put it, “The status quo is not an option.”
For us, that discussion will carry extra weight because one of Oregon’s largest regional landfills sits just north of town.
Coffin Butte Serves More Than Benton County
People think of Coffin Butte Landfill as Benton County’s landfill, but it has operated as a regional disposal site for decades.
Originally established during the Camp Adair era in the 1940s, the landfill later became part of a regional waste system serving much of the mid-Willamette Valley. Today, garbage arriving at Coffin Butte doesn’t just come from Corvallis or Philomath. Waste is transported from multiple counties, including Marion, Linn, Polk, Yamhill, and portions of the Oregon Coast.
That regional role is one reason discussions taking place in Salem could eventually have a direct impact on our county.
Why Counties Are Planning Now
Officials say the region needs a long-term strategy before existing landfill capacity becomes a crisis. In other words, they are trying to solve a problem… before it becomes a problem… and it’s already a problem.
Building an entirely new landfill has become more and more difficult due to environmental regulations, permitting requirements, land availability, and public opposition. No one wants a landfill in their backyard. See the recent article (here) by NPR (KLCC) about Bit By Bit Adaptive Riding and the effects the landfill has had on them. This is an important read… and NPR covered it quite well.
County leaders are exploring a new regional organization that would coordinate disposal capacity, recycling programs, and future infrastructure rather than having each county solve the problem independently.
As one official noted, “If we don’t work together, we’re all going to fail together.” While this statement is true and holds weight, it’d be a shame if Benton County continued to bear most of the burden. We have our solution, we have a landfill, and they don’t. So are we all really going to fail together?
The Future of Coffin Butte
Republic Services has spent years seeking approval to expand the landfill in order to extend its operating life. Supporters arguing the expansion is necessary to maintain regional disposal capacity, while opponents have raised concerns about odors, methane emissions, groundwater protection, truck traffic, and the long-term environmental impacts of continued growth.
After initially approving the expansion in late 2025, the Benton County Board of Commissioners revisited the decision and ultimately reversed course earlier this year, denying Republic Services’ application. That decision remains tied up in ongoing legal and regulatory proceedings.
The proposed expansion would have relocated roads and operational facilities while opening additional disposal areas south of Coffin Butte Road, extending the usable life of the landfill.
A Regional Problem
The discussions happening now acknowledge a reality that extends beyond Benton County.
Every day, thousands of tons of waste generated throughout western Oregon need somewhere to go. Coffin Butte has handled most of that responsibility, making it one of the region’s most important pieces of public infrastructure. Whether the proposed seven-county partnership ultimately moves forward remains to be seen.
It’s hard to draw many conclusions at this point until more information becomes available about the proposed regional authority.
One thing we can conclude is that Republic Services welcomes waste transported from other counties. It brings in additional revenue… additional profits… and more customers. From their perspective, their current “storefront” is too small and they need a bigger space.
It’s also safe to conclude that it adds a burden to our county… and shortens the lifespan of the landfill located in our community.
We shouldn’t be selfish… we are all Oregonians. But should we also protect ourselves, and not bear the burden? It’s a tough one.
