Title: Protection of Stratospheric Ozone: Listing of Substitutes in the Motor Vehicle Air Conditioning Sector Under the Significant New Alternatives Policy (SNAP) Program
Abstract: The Clean Air Act provides for the review of alternatives to ozone-depleting substances and the approval of substitutes that do not present a risk more significant than other alternatives that are available. Under that authority, the Significant New Alternatives Policy (SNAP) program, the EPA is expanding the list of acceptable substitutes for ozone-depleting substances (ODS). The substitute addressed in the first final rule (R-152a) is for the motor vehicle air conditioning (MVAC) end-use within the refrigeration and air-conditioning sector. This substitute does not pose significantly more risk than other substitutes that are available in this end use. Additionally, this substitute is a non ozone-depleting gas and consequently does not contribute to stratospheric ozone depletion. 2nd Final Action: EPA plans to finalize the use of R-744 in the MVAC end-use within the refrigeration and air-conditioning sector. This substitute does not pose significantly more risk than other substitutes that are available in this end use. Additionally, this substitute is a non ozone-depleting gas and consequently does not contribute to stratospheric ozone depletion.
