Phaseout of Ozone-Depleting Substances

Many of more than 37,000 retail food establishments (such as supermarkets, grocery stores, supercenters, and wholesale clubs) in the United States use HCFC-22 (also known as R-22) as their primary refrigerant. HCFC-22 is an ozone-depleting substance (ODS), and it is subject to phaseout under the Montreal ProtocolExit, an international treaty to protect the stratospheric ozone layer. EPA regulations under the Clean Air Act (CFR Part 82, Subpart A) lay out a schedule to phaseout the production and import of ozone-depleting substances (ODS) to meet the requirements of the Montreal Protocol.

  • On January 1, 2003, EPA limited how much and who could import/produce HCFC-22.
  • On January 1, 2010, production and import of virgin HCFC-22 was banned in the United States. Exceptions are available for servicing of equipment made before this date (the so-called “servicing tail”), for export, and for processes resulting in transformation or destruction of the substances.
  • On January 1, 2020, all production and import of virgin HCFC-22 will be banned, with exceptions for export and for processes resulting in transformation or destruction.

EPA also bans the import of used HCFC-22 without prior approval from both EPA and the government representing the country of export.

Leak Repairs

Under Section 608 of the Clean Air Act, EPA has established mandatory leak repair requirements for refrigeration equipment that exceeds certain leak rates. On September 26th, 2016 EPA amended Section 608 regulations. These regulatory requirements may include equipment retirement, equipment repair, or conversion to non-ODS refrigerants.
