Auto Repair Shop Permit Requirements in Tucson, AZ

1. EPA/RCRA Hazardous Waste Generator Requirements

   Auto repair shops that generate hazardous waste (spent solvents, contaminated absorbents, some paint wastes) must determine their generator category under RCRA rules, administered in Arizona by ADEQ. Very small quantity generators (100 kg/month or less) are exempt from the EPA ID requirement; small quantity generators (100-1,000 kg/month) must obtain an EPA ID number. Used oil and antifreeze are generally managed under separate recycling rules rather than as hazardous waste — check ADEQ guidance for your shop's specific waste streams.
