Waste Management Permits and Applications

DEQ issues permits and certifications for certain types of facilities that treat, store, or dispose of wastes as well as for ore processing facilities that use cyanide in their mineral extraction processes. DEQ also oversees these permits and ensures the facilities meet and comply with all applicable laws and permit conditions.

  • Landfills
  • Cyanidation
  • Hazardous Waste Permit
  • Hazardous Waste Siting

Landfills are areas of land or excavations in which wastes are placed for permanent disposal. Certain regulations apply to all municipal solid waste landfills in the state, while others such as ground water monitoring requirements are based on the volume of waste managed. All nonmunicipal solid waste landfills are regulated on the basis of volume and characteristics of waste managed and classified as Tier I, II, or III facilities. Responsibility for regulating municipal and nonmunicipal solid waste landfills in the state is shared between DEQ and the seven public health districts in Idaho. 

Cyanidation is a method of extracting metals from ore using a cyanide solution. Under the “Rules for Ore Processing by Cyanidation” (IDAPA 58.01.13), ore processing facilities that use cyanide in mineral extraction processes are required to obtain a permit from DEQ for construction, operation, and closure. DEQ reviews and approves plans and specifications for all new facilities and modifications or expansions to existing facilities. This ensures that process water and process-contaminated water are safely contained, controlled, and treated to protect human health and the environment.


To construct a new commercial hazardous waste treatment, storage, or disposal facility (TSDF) or expand an existing TSDF in Idaho, the owner must first submit a hazardous waste siting license to DEQ for approval. The siting license includes information about the proposed facility or expansion and details such as description of the types of waste to be handled at the facility, engineering and hydrogeologic information, and emergency and risk management information. A fee is required for each siting license application.

The siting license application requirements are found in Idaho Code § 39-58.

Hazardous Waste Siting License Application Process

The facility siting license fee schedule is provided in the “Rules and Standards and for Hazardous Waste” (IDAPA 58.01.05).
