House Bill No. 3472 amends the Oklahoma Used Tire Recycling Act by modifying the definition of "used tire processing." The bill specifies that, for a five-year period ending on July 1, 2031, tire pyrolysis will be classified as used tire processing. However, after this period, tire pyrolysis will no longer be considered as such. Additionally, the bill clarifies that any tire pyrolysis facility will not be categorized as an advanced recycling facility but rather as a used tire recycling facility, subject to all relevant statutes and regulations.

The bill also includes various definitions related to the recycling of used tires, such as "end use," "tire-derived product," and "used tire," among others. The effective date for this legislation is set for November 1, 2026. Overall, the bill aims to enhance the regulatory framework surrounding used tire recycling in Oklahoma, particularly concerning the treatment of tire pyrolysis within the recycling process.
