List of Hazardous Air Pollutants, Petition Process, Lesser Quantity Designations, Source Category List; Petition To Delist of Ethylene Glycol Monobutyl Ether

The EPA is amending the list of hazardous air pollutants (HAP) contained in section 112(b)(1) of the Clean Air Act (CAA) by removing the compound ethylene glycol monobutyl ether (EGBE) (2-Butoxyethanol) (Chemical Abstract Service (CAS) No. 111-76-2) from the group of glycol ethers. This action is being taken in response to a petition to delete EGBE from the HAP list submitted by the Ethylene Glycol Ethers Panel of the American Chemistry Council (ACC) (formerly the Chemical Manufacturers Association) on behalf of EGBE producers and consumers. Petitions to delete a substance from the HAP list are permitted under section 112(b)(3) of the CAA. Based on the available information concerning the potential hazards of and projected exposures to EGBE, EPA has made a determination pursuant to CAA section 112(b)(3)(C) that there are "adequate data on the health and environmental effects [of EGBE] to determine that emissions, ambient concentrations, bioaccumulation, or deposition of the substance may not reasonably be anticipated to cause adverse effects to human health or adverse environmental effects."
