National Emission Standards for Hazardous Air Pollutants; Manufacture of Amino/Phenolic Resins

Короткий зміст

The proposed rule would reduce air emissions of hazardous air pollutants (HAP) from existing and new sources that manufacture amino or phenolic resins. The proposed rule would implement section 112 of the Clean Air Act Amendments of 1990 (Act) and is based on the Administrator's determination that amino/phenolic resin sources emit HAP identified on the EPA's list of 188 HAP. The resins covered by the proposed rule use formaldehyde as a primary feedstock. The major HAP emitted by sources covered by the proposed rule include formaldehyde, methanol, phenol, xylene, and toluene. Beginning with the first year after sources are required to comply with the proposed rule, the EPA concludes that the proposed rule is estimated to reduce HAP emissions from existing sources by 356 megagrams per year (Mg/yr) from a baseline level of 644 Mg/yr. This is a 55 percent reduction. The published list of source categories included the amino resins production source category and the phenolic resins production source category. These two products can broadly be classified as formaldehyde- based thermosetting resins. These two source categories are being combined into one source category (i.e., the amino/p
