  SUMMARY: On 6 October 2021, the U.S. Environmental Protection Agency issued a supplemental 
proposed rulemaking under the Significant New Alternatives Policy program to list  certain substitutes 
to ozone - depleting substances in the foam blowing sector, extruded polystyrene: Boardstock and 
billet end -use, as acceptable, subject to narrowed use limits, from the effective date of a subsequent 
final rule until 1 January 2023. Thi s followed EPA's 12 June 2020, initial proposal which proposed to 
list three foam blowing agents, which are hydrofluorocarbon blends, as acceptable. Taking into 
consideration information available to EPA since issuance of that initial proposal, EPA propose d 
narrowed use limits and time -limited use of the substitutes in the supplemental proposal. Based on 
further information available to EPA, EPA is now withdrawing the proposed listings for the three foam 
blowing agents described in the initial and supplemen tal proposals. This document summarizes the 
proposed listings and provides an explanation for the Agency's decision not to finalize the proposed 
actions.
