EPA is taking direct final action to list substitutes for ozone-depleting substances (ODSs) in the fire suppression and explosion protection sector as acceptable subject to use restrictions under the EPA's Significant New Alternatives Policy program. This program implements Section 612 of the Clean Air Act, as amended in 1990, which requires EPA to evaluate substitutes for ozone-depleting substances and find them acceptable where they pose comparable or lower overall risk to human health and the environment than other available substitutes.
