This document amends EPA's existing labeling regulations by adding an exemption from the labeling requirements regulations when controlled substances are destroyed, adding an exemption for spare parts that are used in repair, making revisions to clarify the labeling of waste, and making several other minor clarifying revisions. EPA is promulgating these revisions in response to numerous comments, in order to recognize and alleviate the burden placed on specific parties whose activities contribute no additional emissions of ozone-depleting substances. While these changes provide additional flexibility to the regulated community, they in no way compromise the environmental goals and benefits of protecting public health through the labeling regulation.
