Comparison: State vs. Federal
• Rules. "Hazardous substances" is a broad classification that includes hazardous wastes, toxic pollutants, hazardous air pollutants, and certain hazardous chemical substances or mixtures. Arizona does not specifically regulate hazardous substance storage. See the national section HAZARDOUS SUBSTANCE STORAGE for additional guidance.
Arizona has adopted by reference the Uniform Fire Code governing ASTs. See the state section ABOVEGROUND STORAGE TANKS for a discussion of AST requirements in Arizona.
The state's UST program follows the federal rules, with some additional requirements for notification, leak detection, release reporting, corrective action, and closure. See the state sections LEAK DETECTION and UNDERGROUND STORAGE TANKS
