Landfills & Dumps in Idaho

Idaho's solid waste management operates through a shared responsibility between the Department of Environmental Quality (DEQ) and the state's seven public health districts. DEQ approves facility siting and design for all landfills, while public health districts provide day-to-day operational oversight and conduct regular inspections. This collaborative approach ensures both environmental protection and practical waste management across Idaho's diverse geography, from the Boise metropolitan area to remote mountain communities.

The state currently operates six lined municipal landfills meeting federal RCRA Subtitle D standards, along with approximately 17 unlined municipal landfills in less populated areas. As Idaho's population grows, DEQ encourages counties to regionalize solid waste operations and share resources, allowing smaller communities to benefit from modern technology that protects groundwater resources. Construction and demolition landfills, industrial waste facilities, and specialty disposal sites operate under separate regulations with DEQ approval.

Disposal fees vary significantly across Idaho's regions, typically ranging from $20 to $40 for a pickup truck load at most facilities. Some counties charge by weight while others use vehicle-based pricing. Many facilities offer reduced rates or free disposal for separated recyclables and yard waste, encouraging waste diversion. Regional facilities like Southern Idaho Solid Waste serve multiple counties, providing economies of scale that help keep costs manageable for rural residents.

Agricultural waste presents unique considerations in this farming state. Most facilities accept small amounts of farm waste from hobby operations, but large-scale agricultural operations require permitted facilities. Pesticide containers must be triple-rinsed before disposal at any facility. Contact your local public health district or county extension office for guidance on proper agricultural waste disposal options in your area.

Household hazardous waste collection varies by location. Boise and larger cities operate permanent collection sites accepting paint, chemicals, automotive fluids, and other hazardous materials. Rural communities rely on periodic collection events, often held in spring and fall. Check with your county or public health district for schedules. DEQ maintains information about all permitted facilities and can help locate appropriate disposal options for unusual waste types.
