Idaho Department of Environmental Quality (DEQ)

About us

The Idaho Department of Environmental Quality (DEQ) was created by the Idaho Environmental Protection and Health Act (Idaho Code §39-1).
DEQ implements state environmental programs pursuant to state laws and rules. In general, Idaho’s environmental programs meet the requirements of the major federal environmental protection laws, including the Clean Air Act, Safe Drinking Water Act, Resource Conservation and Recovery Act, and a portion of the Clean Water Act. DEQ is authorized to administer state programs in lieu of the US Environmental Protection Agency (EPA) administering these federal acts.
To implement these programs, DEQ engages in a broad range of activities:
Assessing environmental problems
Overseeing compliance by facilities that generate air, water, and hazardous waste pollution
Monitoring Idaho’s air and water quality
Overseeing cleanup of contaminated sites
Responding to hazardous materials and emergency response calls
Issuing permits and authorizations for new and expanding businesses and manufacturing facilities
Administering grant and low-interest loan programs to fund wastewater and drinking water facilities
DEQ does not discriminate on the basis of race, color, religion, sex (including pregnancy and gender identity), national origin, political affiliation, sexual orientation, marital status, disability, genetic information, age, membership in an employee organization, retaliation, parental status, military service, or other non-merit factors in its program or activities.
