Storing Materials Outside

Containers stored outside must have lids to prevent rainwater from filling and causing contents to overflow onto the ground. Some containers are not well sealed, and rainwater “washes” the contents away causing pollutants to drip or drain out of cracks or holes.

Waste containers must be able to securely confine their contents and must have tight-fitting lids. Keeping these containers under cover and in a tub or on a spill pallet designed to catch drips is a good measure to help prevent stormwater contamination.
