Stormwater Pollution Prevention

Businesses can contribute to storm drain pollution mainly through improper use of cleanup practices that allow wastes such as food particles, oil and grease, paint, pesticides and/or cleaning products to flow into the street, storm gutter, or storm drain.

For important information on how to prevent such pollution, please see Stormwater Info.
