How to dispose of pressure-treated wood (including decking and fence boards)

Put treated wood in your black cart as garbage.
Wood that's been stained, chemically treated, pressure treated, painted and/or has nails, screws or other hardware attached is considered treated wood.
Treated wood pieces must be less than:
- 15 cm (six inches) in diameter
- 1.25 m (four feet) in length
Larger sizes or quantities of treated wood
Take larger pieces or amounts of treated wood to a City landfill. Landfill charges will apply.
