Auto Repair Shop Permit Requirements in Dallas, TX

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 federal RCRA rules. Very small quantity generators (100 kg/month or less) are exempt from the federal EPA ID requirement; small quantity generators (100-1,000 kg/month) must obtain an EPA ID number by notifying TCEQ, which administers the hazardous waste program in Texas. Used oil and antifreeze are generally managed under separate recycling rules rather than as hazardous waste — check TCEQ guidance for your shop's specific waste streams.
