Protection of Stratospheric Ozone: Amendment to HFO-1234yf SNAP Rule for Motor Vehicle Air Conditioning Sector


This action would update a rule requirement in the SNAP rule for HFO-1234yf to use the latest edition of a standard from SAE (Society of Automotive Engineers) International. The revised standard would require use of a more robust fitting that is less likely to leak than that currently cited in the March 29, 2011, SNAP rule (76 FR 17488). Updating the standard would reduce emissions and ensure consistency with industry standards.
