The U.S. Environmental Protection Agency wants to list a number of flammable refrigerants as acceptable substitutes for ozone-depleting substances, and wants to exempt the listed substitutes from venting/disposal restrictions.
The EPA's July 9, 2014 Notice of Proposed Rulemaking, under its Significant New Alternatives Policy (SNAP) program, proposes to list acceptable substitutes and their end-use applications, including:
• residential refrigerators and freezers
• stand-alone commercial refrigerators and freezers
• very low temperature refrigeration
• non-mechanical heat transfer
• vending machines
• room air-conditioners
The EPA also proposes to exempt these substitute refrigerants, under certain conditions, from Clean Air Act Section 608's prohibition on venting, release, or disposal the hydrocarbon refrigerant substitutes.
The EPA said it is proposing this exemption on the basis of evidence that venting, release, or disposal would not pose a threat to the environment.
