Other notes
- Bring loads over 25 gallons or 25 items to the landfill facility rather than a mobile site. Damaged or bulging lithium-ion batteries must go to the landfill facility, not mobile sites.
- Electric car batteries are not accepted; return them to a dealer.
- Mobile sites take e-waste under 27 inches (plus LED flat screens); larger electronics go to the landfill Recovery and Diversion Area.
- Source conflict: the HHW contact page lists 208-577-4736 for questions, while the hours and hazardous waste pages list 208-577-4737 for the HHW office. 208-577-4736 is also listed for the Landfill Environmental Compliance Manager.
