Landfill Expansion

Valley Neighbors for Environmental Quality and Safety

The information on this website is current as of 3.15.22.

UPDATE 3-15-22: Republic Services has withdrawn their appeal, but plans to file a NEW application for expansion in the near future. We will update this site as we learn more.

Meanwhile, we will keep the information here about their first application so that people new to the process can learn the history.

Valley Landfills / Republic Services has applied for
a Conditional Use Permit (CUP)

to expand the Coffin Butte Landfill
at the intersection of Highway 99W and Coffin Butte Road,
north of Corvallis and close to Adair Village.

This proposed expansion brings a number of risks and drawbacks to the county, the local region, and the surrounding environment.

  • It would eliminate Coffin Butte Road, a publicly owned and maintained road that is used for everyday travel and is a key emergency evacuation route

  • It would increase traffic congestion and dangers throughout Benton County and surrounding counties

  • More Trash = More Litter, More Noise, More Dust, More Odors, More Risks to Water, More Methane Leakage

What Might This Look Like?

This diagram is a cross-section of Coffin Butte Landfill with the new proposed disposal cell in green. As you look at this diagram, you are standing at the intersection of 99W and Coffin Butte Rd.
The Benton County Courthouse and Statue of Liberty provide a sense of scale to give you a
sense of the anticipated height of the proposed cell.

Why should people living in Benton County, Corvallis, and Adair Village
have to put up with all of these risks and drawbacks?
