EPA new proposed SNAP rule

On July 9, 2014, the U.S. EPA issued a proposed rule which would change the listing status for certain substitutes under the Significant New Alternatives Policy Program (SNAP).

Under this proposed rule, various hydrofluorocarbons (HFCs) and HFC-containing blends that were previously listed as acceptable alternatives to ozone-depleting substances (ODS) will be listed as unacceptable for some uses. This proposed rule is part of the Significant New Alternatives Policy (SNAP) program, under which the EPA continuously reviews alternatives to ODS to find substitutes that pose less overall risk to human health and the environment. As safer alternatives become available for particular applications, the list of acceptable substitutes is evaluated and revised.

Among the proposed changes is the following:

For motor vehicle air conditioning systems in newly manufactured, light-duty vehicles

• HFC-134a as unacceptable starting with model year (MY) 2021; (emphasis added) and

• The refrigerant blends SP34E, R-426A (also known as RS-24), R-416A (also known as HCFC Blend Beta or FRIGC FR12), R-406A, R-414A (also known as HCFC Blend Xi or GHG-X4), R-414B (also known as HCFC Blend Omicron), HCFC Blend Delta (also known as Free Zone), Freeze 12, GHG-X5, and HCFC Blend Lambda (also known as GHG-HP) as unacceptable starting with MY 2017.

Following is a link to the EPA website that contains copies of the proposed rules.
