To dispose of empty, nonrefillable containers as nonhazardous waste, they should be what?

The correct procedure for disposing of empty, nonrefillable containers as nonhazardous waste is to ensure they are triple rinsed or pressure washed. This process effectively ensures that any residue of the herbicide or chemical that might remain in the container is thoroughly removed. Triple rinsing involves filling the container three times with water, shaking it, and then pouring the rinsate out in accordance with the label instructions or local regulations. Pressure washing achieves a similar outcome, using high-pressure water jets to eliminate any remaining substances.

These practices minimize the risk of contamination in landfills and help adhere to environmental regulations aimed at preventing hazardous waste from entering the waste stream. Following this method is crucial for maintaining safety and compliance with regulatory standards regarding waste disposal.
