Asbestos
Asbestos material is accepted at Knott Landfill on Wednesday only. Department approval is required at least 24 hours prior to disposal. There are special packaging requirements for asbestos material (call the Office for different instructions if you only have siding asbestos), and the Department of Environmental Quality ASN-4 form must also be submitted to this department. You can download an application for disposal of Non-Friable  or  Friable asbestos. The minimum charge for asbestos material is $100.00 for up to 2000 pounds. Each additional pound over 2000 is $.05.

Contaminated Soil
Contaminated soil is accepted at Knott Landfill. Like asbestos, department approval is required at least 24 hours in advance. We must also receive a laboratory report showing what contaminates are in the soil and what the levels of those contaminates are. Call the Solid Waste Department at 317-3163 to request a special waste application. The fee to dispose of contaminated soil is $.0175 per pound.

Paint
If the paint is dried and the can is open and exposed, it can be accepted at the disposal sites. We cannot accept any liquids at any of the county disposal sites. The Department of Solid Waste is sponsoring the "Paint Smart" program, which allows county residents to bring their new or used oil and latex-based paint, also stains, to three convenient locations in Deschutes County.

Antifreeze is not accepted at any of our disposal sites. You may take it to Deschutes Recycling at Knott Landfill.  Please call 388-1910 for pricing.  We would also suggest you hold your antifreeze for our Household Hazardous Waste Facility, which will accept items (2) two Fridays and Saturdays per month.  Call 317-3163 to make an appointment.

Other Household Liquid Waste
We are not authorized to accept any liquids. Small household quantities may be absorbed with dirt or kitty litter before bringing them in for disposal.
