WASHINGTON, DC (February 21, 2014)- Congressman Scott Peters (CA-52) and Senator Chris Murphy (Connecticut) led their colleagues in a letter to Gina McCarthy, Administrator of the Environmental Protection Agency (EPA), calling on EPA to take more aggressive action to cut down on production of an industrial “super pollutant” that does 1,800 times more damage to the climate that carbon dioxide. The letter was signed by 17 Senators and 24 Members of the House of Representatives.
In December, EPA unveiled a new proposal to reduce production of HCFC-22, a refrigerant chemical that’s also a potent greenhouse gas. HCFCs — hydrochlorofluorocarbons — are currently being phased-down under the Montreal Protocol, a Reagan-era treaty to end the use of chemicals that harm the ozone layer. HCFCs are used in refrigerators, air-conditioning systems, and foam blowers.
The consensus among the letter’s signatories is that EPA’s initial proposal will still allow far too much new HCFC-22 to be produced, on top of a substantial existing stockpile of the environmentally harmful chemical.

On February 21st, ComfortStar announced that Choice R-421A is approved as the only acceptable R22 alternative refrigerant for all ComfortStar MIA/MIH-NCRdry-nitrogen-charged Air Conditioning units. We are very excited that Choice R-421A is the ONLY R-22 direct replacement covered under warranty for residential A/C by any OEM to date. We feel that this is a major step in the evolution and adoption of Choice R-421A as the preferred R22 replacement in the marketplace.
ComfortStar mentions the following reasons for approving R421A as the only acceptable R22 alternative refrigerant for use in their equipment-
-R421A is an environmentally friendly non ozone depleting replacement for R22
-R421A can replace R22 without modification-
-R421A no hydrocarbons such as butane, and is rated “A1” by ASHRAE
-R421A is non flammable and rated A1 by ASHRAE
-R421A can be used with Mineral, AB, or POE oils*
-R421A is comparable to R22 in terms of performance and pressures, approximately 1% higher at 95°F

*If there is a vertical height difference of 20 feet or more between the evaporator and condensor, the system must be converted to POE.
According to the EPA’s memo (2012 to 2014 Allocation Overview Memo), the EPA will continue to use the same HCFC-22 baseline as established in the 2011 Interim Final Rule. The Final 2012 – 2014 Allocation Rule will provide fewer HCFC-22 consumption allowances relative to the 2009 Final Rule and the same percentage of baseline for HCFC-22 production allowances relative to the 2009 Final Rule.

In HARDI’s December 21st E-Newsletter update entitled “HARDI Advocacy Advisory”, HARDI suggests that “Distributors should prepare for both another delay in the issuance of “no action assurance” letters by the EPA and a further reduction in the amount of R-22 which will be allocated. In 2012, approximately 55 million pounds of R-22 were allowed for production/importation in the United States and it is the recommendation of HARDI that distributors plan for another significant reduction in R-22 availability, likely to 45 million pounds nationally in 2013.”
