There are many different types of spills or discharges that can pollute the environment or create a health or safety hazard. Please report all discharges to storm drains, gutters, ditches and waterway! The discharges into a storm drain system that are not composed entirely of stormwater, prohibited by, with few exceptions, American Canyon Municipal Code 14.28, along with state or federal laws, prohibit the release of anything other than stormwater runoff to the storm drain system. Some examples of illegal discharges include: dumping car fluids, sewage, dirt, concrete, construction waste, paint and excess irrigation runoff. Please help keep our waterways clean!
