Hazardous Waste FAQ

NEVER pour or flush left-over chemicals down the storm drain, sink or toilet. Storm drain water is never treated and enters local creeks and water supplies which leads to contamination. When in doubt, schedule a drop-off. Please call us at 674-8461 to schedule a time to drop off chemicals.

You can reach the Solid Waste Division Monday – Saturday from 7:30 AM – 5:30 PM at (307) 674-8461.

If the product label reads “use with caution”, “flammable” or “keep away from children”, it is most likely a hazardous substance. If you are unsure, it is best to ask before disposing of the product.  Please call the Landfill at 674-8461.

We ask that you please call the Landfill at 674-8461 and make an appointment to drop off hazardous waste. This allows us to manage storage for the type and amount of household wastes being dropped off at the facility.  Currently, we are accepting Household Hazardous Waste on Wednesdays by appointment only.  Due to the amount of Household Hazardous Waste that we have been receiving, same day appointments are not usually possible.  Please contact us at least the day before to schedule an appointment time at 674-8461.

The cost for dropping off household hazardous waste is free to all residents of the City of Sheridan and Sheridan County, but businesses (including non-profit or government) are required to pay a fee. Please call the facility at (307) 674-8461 for more information on the cost for businesses.
