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 Jan. 1, 1996. The EPA allocates essential use allowances for production and import of a specific quantity of Class I substances solely for the designated essential purpose. Medical devices and laboratories are generally the two remaining exemptions.
The final rule became effective June 24, 2009.
