Sept. 29: Last Day (This Year) for Free Noxious Weeds Disposal

San Juan County's 2025 Noxious Weeds Disposal program ENDS September 30, 2025. That means the last day to bring qualifying noxious weeds to the Lopez Dump for no-charge disposal will be Monday, September 29.

Residents across the county take advantage of this program to control and dispose of noxious weeds in a way that prevents spread — so much so that this year's funds for the program have been used up! SJC hopes to offer the program again in 2026.

Starting October 3 and for the remainder of the year, noxious weeds will need to be paid for with your regular garbage. Alternatively, the county has shared this link to a resource describing methods of responsible control and disposal: https://www.nwcb.wa.gov/pdfs/Noxious_weed_disposal_2012-1.pdf.

According to SJC's recent press release, "If you think you have noxious weed lurking in your spaces but you aren’t sure, check out the weed ID tab on our page or send us a photo by email:  noxiousweeds@sanjuancountywa.gov." You can also call 360-376-3499.
