Protection of Stratospheric Ozone: Extension of Global Laboratory and Analytical Use Exemption for Essential Class I Ozone Depleting Substances

EPA is taking final action to extend the global laboratory and analytical use exemption for production and import of class I ozone- depleting substances from December 31, 2005, to December 31, 2007, consistent with recent actions by the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer. The exemption allows persons in the United States to produce and import controlled substances for laboratory and analytical uses that have not been already identified by EPA as nonessential.
