Waste Pesticide Collection Program

This program collects unwanted/unusable pesticides, spray mixtures, and unrinsed pesticide containers from agricultural or commercial operations. Household pesticides can be disposed of through the Household Hazardous Waste Program. Collection events will be posted here as they are announced.  

The March 16 collection event scheduled for Madras has been postponed until mid-April because of unprecedented snow accumulations in Jefferson County. The exact date, time and location for this rescheduled event will be posted here prior to March 22. 

Due to on going negotiations between the state and hazardous waste contractors (which have not yet been finalized), the Pesticide Stewardship Partnership has not scheduled any additional waste pesticide collections for the remaining period between March and June 30, 2019.

Many people have expressed interest in participating in a collection event in the near future. In recognization of this need, the Pesticide Stewardship Partnership is exploring alternative possibilities of holding an event at a location in the Willamette Valley in late April or early May 2019. Any progress toward establishing such an event will immediately be posted here. We apologize for this inconvenience, and are working diligently to provide this much valuable service to our customers in western Oregon. If you have any questions, please email Kirk V. Cook​ or call (541) 841-0074.
