  • Cleaners – Store cleaning products where they are protected from rain, and prevent spills from reaching the storm drain system.
  • Chemicals – Any materials used or waste generated must be managed according to state regulations. Use secondary containment to prevent accidental discharge or leaks.
  • Equipment – Store materials like batteries and machinery in trays or with drip pans to contain potential leaks and spills.
  • Trash – Keep dumpster lids closed and place covers on all waste containers. Never put liquid waste into a dumpster. Store outdoor waste receptacles under cover to reduce exposure to rain that could wash pollutants into the storm drain system.

  • Surface Cleaning – Regularly sweeping parking lots and areas around your business prevents pollution. Hosing oil, grease, soap and other pollutants into the storm drain system can result in a fine.
  • Wash Water – Even if labeled non-toxic or biodegradable, all cleaning solutions can harm wildlife and our watersheds. Dispose of all non-hazardous wash water into indoor drains like sinks and toilets.
  • Hazardous Spills – Keep spill kits near stored chemicals or bulk cleaning agents. Use absorbent mats or socks to prevent accidental spills from reaching the street or storm drain system.
  • Parts/Equipment – Use self-contained sinks and tanks when cleaning parts with degreasing solvents. Consider switching to a water-based cleaning solution. Use pans to catch leaks when working on engines or machinery.
