The CleanSweep NY program is coming to region 5 this Spring (April 2016) and will accept old unwanted pesticides from agriculture and non-agriculture establishments (not homeowners) for proper disposal free of charge. They will also accept other chemicals for a nominal charge.
Their plan is to have at least 2 collection sites, 1 in Plattsburgh and 1 in Hudson Falls.
Registration is required but there’s no enforcement potential.
They can be reached at 1-877-793-3769 or www.cleansweepny.org
