Auto Repair Shop Permit Requirements in Los Angeles, CA

1. EPA/RCRA Hazardous Waste Generator Requirements

   California is stricter than federal law: used oil and most spent antifreeze are hazardous wastes under state law, and California does not recognize the federal very-small-quantity-generator exemption — nearly all auto repair shops generating hazardous waste must obtain an EPA ID number through DTSC before waste is transported. Check DTSC guidance for your shop's specific waste streams.
