1. What is the purpose of this rule?

The Clean Air Act requires EPA to establish standards to control HAP emissions from source categories identified under section 112(c) of the Act.  An initial source category list was published by EPA in 1992.  This list identified Printing, Coating, and Dyeing of Fabrics and Other Textiles as a source category because it contains major source of HAP emissions. EPA estimated that there are over 135 major source facilities. The principal HAP emitted by these sources includes toluene, methyl ethyl ketone (MEK), methanol, xylenes, methyl isobutyl ketone (MIBK), methylene chloride, trichloroethylene, and formaldehyde. The purpose of this rule is to reduce nationwide organic HAP emissions from these major sources. It is expected that approximately 60 percent of nationwide organic HAP emissions from facilities in this source category will be eliminated.
