As a result, “R441A may be sold in new vending machines as of May 23, 2012”, and EPA will initiate the rule-making procedure, with R441A expected to be listed on the Federal Register within the next 24 months.
According to A.S. Trust & Holdings, use conditions will likely limit the charge to 150 g.
EPA also recently indicated that a draft rule on the use of CO2 in vending machines will be prepared by the end of 2012.
Over 3 million vending machines are currently in operation in the US.
