Pesticide Waste Management Requirements
• First determine if pesticides are considered “waste” à still a “product” if legitimate use is viable option
• Pesticide wastes fall under Oregon & federal rules – Streamlined requirements for pesticide wastes if …
• Meet conditions outlined in rules: – Keep the waste in a closed, non-leaking container – Label the waste container with the words “Pesticide
Waste” or “Universal Waste - Pesticides” – Contain and cleanup any leak or spill – Ensure delivery to appropriate collection site or facility
![Page 4: Chemical)Applicators)ShortCourse) · Calibration Project (Hood River, OR) The Patternator B. Yamhill SWCD: “Tunnel Sprayer” for spray optimization & drift reduction on small fruit](https://reader033.fdocuments.in/reader033/viewer/2022051923/60108c9084a7ad3545754dfb/html5/thumbnails/4.jpg)
Where Can You Take Waste Pesticides?
• County-Run Hazardous Waste Facilities or Collection Events – Most county facilities that take household haz waste will
accept commercial wastes under certain quantities – Small businesses and ag producers must pre-register and
bring in waste on designated days – Most counties charge businesses and ag producers a per
pound or per gallon fee (except in Hood, Wasco and Sherman) - $1.00 to $2.00 per pound

Managing Empty Pesticide Containers
• Empty pesticide containers must be triple-rinsed before being recycled or disposed as solid waste
• If product remains, manage as chemical waste (small containers will be “lab-packed”)
• Where to take empty triple-rinsed plastic pesticide containers? – Agri-Plas à Oregon pesticide
container recycler (503) 390-2381 – Contact pesticide product distributors – Some pesticide waste collection events
![Page 9: Chemical)Applicators)ShortCourse) · Calibration Project (Hood River, OR) The Patternator B. Yamhill SWCD: “Tunnel Sprayer” for spray optimization & drift reduction on small fruit](https://reader033.fdocuments.in/reader033/viewer/2022051923/60108c9084a7ad3545754dfb/html5/thumbnails/9.jpg)
How Are Collected Pesticide Wastes Ultimately Disposed?
• Most pesticide wastes are destroyed through high temperature incineration – Facilities outside Oregon
that follow strict air and waste control permit requirements
• A few types are disposed at hazardous waste landfills – e.g., lead arsenate, other
metal-bearing wastes
![Page 10: Chemical)Applicators)ShortCourse) · Calibration Project (Hood River, OR) The Patternator B. Yamhill SWCD: “Tunnel Sprayer” for spray optimization & drift reduction on small fruit](https://reader033.fdocuments.in/reader033/viewer/2022051923/60108c9084a7ad3545754dfb/html5/thumbnails/10.jpg)
• Buy only what you need - use what you purchase
• Reuse rinsates whenever possible as make-up water
• Will distributor take back unused pesticides in original containers as reusable product?

Managing Pesticide Spills
• Oregon spill rules apply to any spill of a hazardous material to the environment
• If spill occurs, do the following: 1. Activate alarms or otherwise warn
persons in the immediate area 2. Undertake every reasonable method
to stop the spill and contain it; and 3. If there is a medical emergency or
public safety hazard call 911; and 4. Report the spill if required à approx.
25 gals of pesticides, but…. when in doubt, REPORT! 1-800-452-0311 – Oregon Emergency Response
![Page 18: Chemical)Applicators)ShortCourse) · Calibration Project (Hood River, OR) The Patternator B. Yamhill SWCD: “Tunnel Sprayer” for spray optimization & drift reduction on small fruit](https://reader033.fdocuments.in/reader033/viewer/2022051923/60108c9084a7ad3545754dfb/html5/thumbnails/18.jpg)
Additional Actions to Take When Spills Occur
ü Move away or upwind from the spill if you detect an odor and are unsure if it is safe
ü Avoid contact with liquids or fumes. ü Keep non-emergency people out of the area ü If deemed safe, clean up what you can as soon as practical ü Remove clean up materials to an approved facility or discuss
use or reuse with a DEQ cleanup project manager.

What are the Pathways for Pesticides to Enter Environment?
Spills à to surface or groundwater Leaching à from soil into groundwater Runoff à water transport to surface water Erosion of soil à sediments to surface water Aerial Drift à direct to surface water or runoff Volitilization à ambient air (e.g., soil fumigants)
