This document is a fact sheet about proposed air toxics rule for Rubber Tire Manufacturing. The rulemaking proposes to apply MACT (maximum achievable control technology) requirements to major sources that produce rubber tires and/or their components. There are 43 major sources in this source category owned by 14 companies. The emission sources include rubber processing, cement and solvent usage, tire cord production, and puncture sealant application. Hexane, toluene, formaldehyde, styrene, and methanol are the primary pollutants emitted by these sources. The proposed standards are based on the minimum control requirements of section 112 of the Clean Air Act (i.e., the MACT floor). The largest emissions source at these
plants is the use of solvents and cements to hold the tire components together during the manufacturing process until the tire is formed and cured. The proposed standards for this source are based on the use of pollution prevention techniques to reduce the use of air toxic-containing solvents and cements to almost zero.
