Hazardous Waste Generators Map

There are approximately 2,400 locations in Missouri that generate enough hazardous waste to be regulated by HWP. Click the map to see where these hazardous waste generators are located. 

HWP maintains information regarding the location and waste generation history of companies that generate hazardous waste in Missouri or ship waste to Missouri. The program uses this information to support the collection of fees and taxes.

Hazardous waste, by definition, poses a threat to human health or the environment because of its quantity or characteristics. It may be a liquid, sludge, solid or gas.
