Petition To Delist Hazardous Air Pollutant: 2-Butoxyethyl Benzoate (2-BEB)

The U.S. Environmental Protection Agency (EPA or Agency) is proposing to grant a petition to remove 2-Butoxyethyl benzoate (2-BEB) (Chemical Abstract Service (CAS) No. 5451-76-3) from the glycol ethers category in the list of hazardous air pollutants (HAP) in Clean Air Act (CAA). The EPA proposes to find that there are adequate data on the health or environmental effects of 2-BEB to support the request for removal. This action also details a streamlined approach to the review process of future petitions.
