The Hazardous Waste Inspections and Compliance Unit conducts inspections and follow-up compliance activities at facilities that generate hazardous waste. These facilities include:

• Large quantity generators (LQGs)
• Small quantity generators (SQGs)
• Treatment, storage & disposal facilities (TSDFs)
• Transporters

The purpose of inspection is to ensure that facilities are treating, storing and disposing of their generated hazardous waste in accordance with the hazardous waste regulations. The unit monitors the actions necessary for a facility to return to compliance and also initiates penalty actions for severe violations of the regulations. It also responds to citizen complaints dealing with improper storage and disposal of hazardous waste.

To file a complaint about possible improper storage and disposal of hazardous waste, please call (602) 771-4422 or toll-free at (800) 234-5677.

The Hazardous Waste Inspections and Compliance Unit receives approximately 100 to 125 complaints every year. In most cases, the unit responds to complaints with five working days.

Please note: The department is required to ask for the complainant's name in accordance with A.R.S. § 41-1010. However, if releasing a complainant's name could result in substantial harm, the name can remain confidential.
