Leaving waste unattended while we are closed is considered illegal dumping. These facilities are under 24 hour surveillance and you will be fined for the illegal dumping that is putting surrounding residents and workers in harms way.
We do not have appropriate staff available everyday, so please respect our posted hours and days of service found here.
Thank you for properly managing your household hazardous waste!
We get life happens, and you may want to come earlier or later than your appointment time or on a day that works better for your schedule. That is why we welcome walk in’s during operating hours and fluctuating your appointment time with no advanced notice! You are also not required to print a confirmation sheet!

HHW Recycling Tips
How to Prepare HHW for Transport
- Pack waste carefully in a box or plastic storage container to prevent spillage during transport
- Do not mix chemicals! Arrange similar chemicals together when packing your car. Put pesticides together, solvents together, paints together in their own boxes
- Make sure chemicals are not leaking and lids are tightly sealed. If they are not sealed, place them in a separate container for transport
- Keep products in their original container. Label materials that are not in their original container. If you do not know what the substance is, transport it in its own box and let us know it is an unknown substance
- Place your box of household hazardous waste in the trunk of your car or in the bed of your truck
- Drive directly to the HHW disposal site carefully and let staffed personnel unload your chemicals once you arrive
