2060-AV25 202110 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2060 Office of Air and Radiation OAR 2000 Environmental Protection Agency EPA Protection of Stratospheric Ozone: Listing of HFO-1234yf Under Significant New Alternatives Policy Program for Motor Vehicle Air Conditioning in Nonroad Vehicles and Servicing Fittings for Small Cans

EPA has received a number of manufacturers' submissions concerning listings of substitutes under the Significant New Alternatives Policy program. This rule would propose listings based upon EPA's evaluation of one of these substitutes, HFO-1234yf, for use in motor vehicle air conditioning (MVAC). Such a listing would provide additional flexibility for industry stakeholders to use HFO-1234yf in MVAC systems of certain newly manufactured nonroad vehicles and would allow for the safe and effective servicing of MVAC systems with refrigerant contained in small cans.
