Substitute House Bill No. 6486, Public Act No. 23-62, is a legislative act that establishes a tire stewardship program in the state, effective from October 1, 2023. The program requires tire producers or their designees to join a tire stewardship organization, which is responsible for creating a plan to manage the collection, recycling, and education regarding discarded tires. The plan, which must be approved by the Commissioner of Energy and Environmental Protection, is funded by the producers and utilizes existing service providers and infrastructure. The bill does not modify existing legal language but introduces new provisions for the management of discarded tires.

The bill mandates that tire stewardship organizations submit an annual report on the tonnage of tires collected and recycled, and an evaluation of the program's effectiveness. Additionally, an audit of the program is required every two years or upon the Commissioner's request. The Commissioner is also responsible for evaluating the program three years after a plan's approval and may enforce provisions through civil action. The bill grants immunity from antitrust law claims to producers and organizations acting under this section, allows for collaboration with other states, and requires the Commissioner of Transportation to test tire-derived asphalt. Non-participating producers are prohibited from supplying tires in the state. The bill was approved on June 27, 2023.
