Hazardous Materials

Many items that are regularly used around the house can pose a serious threat to your family's health and/or environment if they are not used and disposed of properly. Kootenai County provides a Household Hazardous Waste (HHW) Collection facility at both of our transfer stations to responsibly dispose of these household chemicals.

Kootenai County's HHW program is provide in conjunction with Idaho Department of Environmental Quality (Idaho DEQ) and Panhandle Health District (PHD)


Each facility allows residents of Kootenai County to drop off up to 10 gallons of HHW per collection day. This free program is only available to residential customers; no commercial customers are allowed to use this service. 

When bringing in material for hazardous waste drop off, please alert the inbound scale house attendant that you have material to drop off. 

After arriving at the hazardous waste area, please turn off your vehicle and no smoking. Please stay in your vehicle, an attendant will be with you shortly. Be prepared to inform the attendant of the type, quantity and location of the waste within your vehicle. The attendant will either remove the hazardous waste from your vehicle or communicate with you on the preferred method of removal.

Household Hazardous Waste Exchange Program

The household hazardous waste exchange program are in the hazardous waste area at both transfer stations, check out our free exchange program. Attendants sort through the material collected in the hazardous waste program and offer up useable material to the general public on a specified cart near hazmat receiving. Residents of Kootenai County, over the age of 18, who sign a waiver, can utilize this service by selecting up to five free products to be reused per day. The reuse program operates at the same times as the hazardous waste program at each site. This program is available only to residential customers; no commercial businesses may utilize this program.
