Green spill
Dumping of materials into the system is not only a bad idea: it's against the law. This includes the following:

  • Paint or solvents
  • Soaps and detergents
  • Chemicals (herbicides, pesticides, fungicides, fertilizer, industrial chemicals, cleaning chemicals, etc)
  • Household wastes (including cooking grease and oil)
  • Oil, grease, gasoline or other automotive fluids
  • Solids and trash
  • Concrete
  • Sewage
  • Yard waste
  • Swimming pool chemicals (for swimming pool or spa draining discharge, please call us at the number below for guidance on how to do it safely.)

If you see any of these unauthorized discharges (illicit discharges), please call the Spill Hotline during normal business hours, or make an Illicit Discharge Citizen Report. If you feel that this is an emergency, please dial 911 and dispatch will alert the appropriate personnel.
