Protection of Stratospheric Ozone: Listing of Global Warming Potential for Ozone-Depleting Substances

Resumo

With this proposed action, the Environmental Protection Agency (EPA or the Agency) lists the global warming potentials for ozone- depleting substances that are included as class I and class II controlled substances, or have been added as class I or class II controlled substances, under authority of section 602(e) of the Clean Air Act Amendments of 1990 (CAA). Class I and class II controlled substances are more fully described in a final rule previously published in the Federal Register on May 10, 1995. To meet EPA's statutory obligation under the CAA, this proposed listing cites the global warming potentials contained in the document, Scientific Assessment of Ozone Depletion: 1994, published by the United Nations Environment Programme (UNEP) in early 1995. As stated in the CAA, the listing of global warming potentials for class I and class II controlled substances ``shall not be construed to be the basis of any additional regulation under this Act.''
