Protection of Stratospheric Ozone: Manufacture of Halon Blends, Intentional Release of Halon, Technician Training and Disposal of Halon and Halon-Containing Equipment

This final rule bans the manufacture of halon blends; prohibits the intentional release of halons during training of technicians and during testing, repair, and disposal of halon- containing equipment; requires appropriate training of technicians regarding emissions reduction; and requires proper disposal of halon and of halon-containing equipment. Release of halons to the environment contributes significantly to the depletion of the stratospheric ozone layer which, in turn, can lead to increased incidences of skin cancer and other ill effects. EPA proposed these requirements in response to a lawsuit filed by the Sierra Club. EPA understands that the manufacturers which have in recent years been engaged in the manufacture of halon blends will be minimally impacted by the ban, or may meet criteria for exemption from this ban. Furthermore, EPA understands that that entities using halons, driven in part by the economic value of halons, currently widely practice the kinds of precautions codified in this rule. This rule will more fully extend these practices throughout the industry and will ensure their continued implementation in the event of changes in halon market conditions. Thus, this rule will assure continued significant environmental benefits, while placing only minimal burdens on industry.
