Revised On: March 14, 2024 - 3:07 p.m.

What Are Considered Waste/Used Tire Facilities?

Waste/used tire facilities are categorized by the number and type of tires stored on the site. There are two types of tires:

  1. Waste tires1 are a motor vehicle tires that are no longer suitable for their originally intended purpose due to wear, damage, improper repair or manufacturer recall.
  2. Used tires2 include any tires that have been used for more than one day on a motor vehicle.

Waste/used tire facility rules are enforced by ADEQ's Waste Tire Compliance/Enforcement Program. The program is primarily involved with waste/used tire disposal activities relating to complaints, inspections and enforcement actions.

If you suspect improper storage or disposal of waste tires, contact the Solid/Hazardous Waste Complaint Line at 602-771-4673.
