Aboveground storage tanks (ASTs) – Idaho

Most regulations affecting ASTs are found at the state and local level. Check with your state and local agencies to see if there are more stringent AST requirements that you need to know about.

Petroleum ASTs in Idaho are regulated by EPA, under the federal Spill Prevention, Control, and Countermeasure (SPCC) rule. Although the Department of Environmental Quality (DEQ) does not regulate ASTs in Idaho, state rules require that the agency be notified within 24 hours if a petroleum release occurs from an AST to the environment.

Hazardous waste ASTs and ASTs utilized for used oil are regulated by DEQ’s Hazardous Waste Program. ASTs containing materials that are hazardous but not consider waste are regulated by other agencies.

Releases of hazardous materials must be immediately reported to DEQ. Local fire districts, cities, and counties may have additional AST ordinances or best management practices.
