Listing of Ozone Depleting Substitutes in Foam Blowing Fact Sheet


On March 19, 2007, the U.S. Environmental Protection Agency (EPA) finalized a rule determining that two ozone depleting chemicals scheduled to be phased out in 2010, HCFC-22 and HCFC-142b, are unacceptable substitutes under the Significant New Alternatives Policy (SNAP) Program (section 612 of the Clean Air Act) as foam blowing agents for CFCs and HCFC-141b. This rule expedites the transition of HCFC-22 and HCFC-142b to alternatives which contributes to the accomplishments of the Montreal Protocol.

EPA issued this rulemaking as a result of progress within the insulation foam industry on adopting non-ozone depleting chemicals.
