Abstract:
The zipped file 'polymact.zip' contains 2 WordPerfect files: (1) a Preamble describing the issues and basis for the proposal;(355KB and ~204 pages) (2) a Propsed Rule containing the regulatory language as published in the Federal Register (200KB and ~69 pages). The proposed rule will reduce emissions of hazardous air pollutants (HAP) from existing and new facilities that manufacture polyether polyols and are located at major source plant sites. The analyses used in the Preamble are based on 78 plant sites producing 10 tons or more/yr. of polyether polyols. Polyether polyols are used to make a variety of products. Urethane grade polyether polyols are used as raw material in the production of polyurethanes, including slabstock and molded flexible foams, rigid foams, and other polyurethanes including microcellular products, surface coatings, elastomers, fibers, adhesives, and sealants. Nonurethane polyether polyols are used as surfactants, lubricants, degreasing agents, hydraulic fluids, cosme tics, and pharmaceuticals.
In the production of these polyols, HAP are used primarily as reactants or extraction solvents. The HAP emitted by the facilities covered by this proposed rule include ethylene oxide (EO), propylene oxide (PO), hexane, toluene, and incidental emissions of several other HAP. Some of these pollutants are considered to be probable human carcinogens when inhaled and all can cause toxic effects following exposure. The proposed rule is estimated to reduce emissions of these pollutants by 1,810 Mg/yr. Because all of the pollutants are also volatile organic compounds (VOC), which are precursors to ambient ozone, the proposed rule would aid in the reduction of tropospheric ozone.
