With this action, EPA is allocating essential use allowances for import and production of Class I ozone-depleting substances for calendar year 2009. Essential use allowances enable a person to obtain controlled Class I ozone depleting substances as part of an exemption to the regulatory ban on the production and import of these chemicals, which became effective January 1, 1996. EPA allocates essential use allowances for production and import of a specific quantity of Class I substances solely for the designated essential purpose. The allocation in this action is 63.0 metric tons of chlorofluorocarbons for use in metered dose inhalers for 2009.
